Just come back from a great weekend up the Lakes doing a solo Borrowdale Bash attempt. I had a great tale though diidn’t quite complete the rocky mammoth…
I drove up to the Hazelwood B & B in Keswick Friday evening from work. This confirmed my previously through travel time to the lakes as about 4 1/2 hours on a Friday evening for the 150 miles journey though I was surprised at the -5 degrees temperate reading as I drove down the A66. On arrival I secured my bike, unpacked, and snuggly donned the hat, gloves and an extra fleece as I braved the elements to conquer my first goal - battered sausage and chips from the Keswick chippy. Yum yum, especially when they got washed down with a Guiness. Anyhow, an early return to bed would set me up for the tough ride Saturday.
Saturday morning was very tough before I even got out of bed. I normally leave my curtains slightly open to allow sunlight to wake me. However, by 7.30 it was still dark, and only dawn at 8am. Really didn’t’ feel like getting up, but the thought of a full English was sufficient to get me dressed and downstairs. Breakfast munched, and biking clothes on, there was no longer an excuses, the slight rumbling doubt as to my abilities for a Lake District ride left quickly as I followed the road out of Keswick through Grange to Seatoller. Yep, first admission, I missed the Watendlath section, mainly due it containing over 1/2 of the total ascent of the proper route, and I didn’t think the knee was upto it, as I was later found to be correct. Instead, following the road eventually got me to the bus stop in Seatoller where I promptly despatched a Ginsters ham and cheese pastie. Oh, and I found out what the weird ‘wettish’ noise from the rear of the bike was - a slipping seatpost found my rear crud catcher catching against the tire - the resolution was to raise and twist the seatpost again to upright / straight, and tighten the quick release to steel bending pressures. Sorted.
Now then, enough faffing (my excuse was letting lunch ‘settle’), better start climbing the Honister Pass. For my wimpy being, this is real tough, harder than the Buttertubs, or at least steeper. Had to push the last 50 metres or so to the bridleway right. Onto the Allerdale Ramble which redefined the term Bridleway to me. I must have walked about 20% of this path down to Grange. The reason? Wet rocks * chance of broken teeth * my bravery equaled walking the sheer slate sections. the real bumpy stuff wasn’t so bad, but a few rock gardens were just too much for me. Unfortunately, as I tried walking (well, easy scrambling actually!) the knee packed in again. As soon as I got on the bike, it would be fine, but it was incredibly frustrating riding 100 metres to have to get off and push 10. Still, the last bit was a blast and I got truly thrown around on a couple of rocky bits, and nobody warned me there would be wet roots at the bottom also, though Cannock prepared me for those.
At Grange, I put away a couple of flapjacks and made my final decision - to avoid the last bit of the Allerdale Ramble incase it meant more walking. Instead the road ride back was a blast (downhill) and a struggle (uphill). Still a few nice photos were taken over Derwent Water and I might even post these when I get the Mac / Windows Mobile phono to talk nicely but enough of that in this post….
Got back to base at about 14:30 where I showered, changed and headed into Keswick for some grub. Went to the Bank Tavern as the Gun and Dog was rammed. I was very impressed with a tasty Lamb in mint gravy with jacket spud and veg. I don’t eat a whole load of lamb, but when in Rome…. This was honestly then nicest lamb I have ever eaten. Another pint of the black stuff put me in the desired sleepy state to mong at the B&B in front of saturday night telly.
This morning, I spent some time driving the Buttermere / Crummock Valley then down through Windermere back home. Great weekend and am thoroughly shattered, just right for work tomorrow :)

Detailed Description
MapGestureArea objects are used as part of a Map, to provide for panning, flicking and pinch-to-zoom gesture used on touch displays, as well as two finger rotation and two finger parallel vertical sliding to tilt the map.
A MapGestureArea is automatically created with a new Map and available with the gesture property. This is the only way to create a MapGestureArea, and once created this way cannot be destroyed without its parent Map.
The two most commonly used properties of the MapGestureArea are the enabled and acceptedGestures properties. Both of these must be set before a MapGestureArea will have any effect upon interaction with the Map. The flickDeceleration property controls how quickly the map pan slows after contact is released while panning the map.
Performance
The MapGestureArea, when enabled, must process all incoming touch events in order to track the shape and size of the "pinch". The overhead added on touch events can be considered constant time.
Example Usage
The following example enables the pinch and pan gestures on the map, but not flicking. So the map scrolling will halt immediately on releasing the mouse button / touch.
Map { gesture.enabled: true gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture }
Property Documentation
This property holds the gestures that will be active. By default the zoom, pan and flick gestures are enabled.
- MapGestureArea.NoGesture - Don't support any additional gestures (value: 0x0000).
- MapGestureArea.PinchGesture - Support the map pinch gesture (value: 0x0001).
- MapGestureArea.PanGesture - Support the map pan gesture (value: 0x0002).
- MapGestureArea.FlickGesture - Support the map flick gesture (value: 0x0004).
- MapGestureArea.RotationGesture - Support the map rotation gesture (value: 0x0008).
- MapGestureArea.TiltGesture - Support the map tilt gesture (value: 0x0010).
This property holds the rate at which a flick will decelerate.
The default value is 2500.
This property holds the maximum zoom level change per pinch, essentially meant to be used for setting the zoom sensitivity.
It is an indicative measure calculated from the dimensions of the map area, roughly corresponding how much zoom level could change with maximum pinch zoom. Default value is 4.0, maximum value is 10.0
This read-only property holds whether the pan gesture is active.
Note: Change notifications for this property were introduced in Qt 5.5.
This property holds whether the mouse events may be stolen from this MapGestureArea.
If a Map is placed within an item that filters child mouse and touch events, such as Flickable, the mouse and touch events may be stolen from the MapGestureArea if a gesture is recognized by the parent item, e.g. a flick gesture. If preventStealing is set to true, no item will steal the mouse and touch events.
Note that setting preventStealing to true once an item has started stealing events will have no effect until the next press event.
By default this property is false.
This read-only property holds whether the two-finger rotation gesture is active.
This QML property was introduced in Qt Location 5.9.
This read-only property holds whether the two-finger tilt gesture is active.
This QML property was introduced in Qt Location 5.9.
Signal Documentation
This signal is emitted when the map stops moving due to a flick.
The corresponding handler is onFlickFinished
.
This signal is emitted when the map is flicked. A flick starts from the point where the mouse or touch was released, while still in motion.
The corresponding handler is onFlichStarted
.
This signal is emitted when the map stops moving due to user interaction. If a flick was generated, this signal is emitted before flick starts. If a flick was not generated, this signal is emitted when the user stops dragging - that is a mouse or touch release.
The corresponding handler is onPanFinished
.
This signal is emitted when the map begins to move due to user interaction. Typically this means that the user is dragging a finger - or a mouse with one of more mouse buttons pressed - on the map.
The corresponding handler is onPanStarted
.
pinchFinished(PinchEvent event) |
This signal is emitted at the end of a pinch gesture.
The corresponding handler is onPinchFinished
.
See also pinchStarted and pinchUpdated.
pinchStarted(PinchEvent event) |
This signal is emitted when a pinch gesture is started.
The corresponding handler is onPinchStarted
.
See also pinchUpdated and pinchFinished.
pinchUpdated(PinchEvent event) |
This signal is emitted as the user's fingers move across the map, after the pinchStarted signal is emitted.
The corresponding handler is onPinchUpdated
.
See also pinchStarted and pinchFinished.
rotationFinished(PinchEvent event) |
This signal is emitted at the end of a two-finger rotation gesture.
The corresponding handler is onRotationFinished
.
This QML signal was introduced in Qt Location 5.9.

#consistent_read ⇒ Boolean
(rw)
A Boolean value that determines the read consistency model during the scan:
If
ConsistentRead
isfalse
, then the data returned fromScan
might not contain the results from other recently completed write operations (PutItem
,UpdateItem
, orDeleteItem
).If
ConsistentRead
istrue
, then all of the write operations that completed before theScan
began are guaranteed to be contained in theScan
response.
The default setting for ConsistentRead
is false
.
The ConsistentRead
parameter is not supported on global secondary
indexes. If you scan a global secondary index with ConsistentRead
set to true, you will receive a ValidationException
.

The primary key of the first item that this operation will evaluate.
Use the value that was returned for LastEvaluatedKey
in the
previous operation.
The data type for ExclusiveStartKey
must be String, Number or
::Aws::Binary
. No set data types are allowed.
In a parallel scan, a Scan
request that includes
ExclusiveStartKey
must specify the same segment whose previous
Scan
returned the corresponding value of LastEvaluatedKey
.

#expression_attribute_names ⇒ Hash
<String
,String
> (rw)
One or more substitution tokens for attribute names in an
expression. The following are some use cases for using
ExpressionAttributeNames
:
To access an attribute whose name conflicts with a
::Aws::DynamoDB
reserved word.To create a placeholder for repeating occurrences of an attribute name in an expression.
To prevent special characters in an attribute name from being misinterpreted in an expression.
Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:
Percentile
^
The name of this attribute conflicts with a reserved word, so it
cannot be used directly in an expression. (For the complete list of
reserved words, see Reserved Words in the Amazon ::Aws::DynamoDB
Developer Guide). To work around this, you could specify the
following for ExpressionAttributeNames
:
\{"#P":"Percentile"\}
^
You could then use this substitution in an expression, as in this example:
#P = :val
^
For more information on expression attribute names, see Specifying
Item Attributes in the Amazon ::Aws::DynamoDB
Developer Guide.

#expression_attribute_values ⇒ Hash
<String
,Types::AttributeValue> (rw)
One or more values that can be substituted in an expression.
Use the : (colon) character in an expression to dereference an
attribute value. For example, suppose that you wanted to check
whether the value of the ProductStatus
attribute was one of the
following:
Available | Backordered | Discontinued
You would first need to specify ExpressionAttributeValues
as
follows:
\{ ":avail":\{"S":"Available"\}, ":back":\{"S":"Backordered"\},
":disc":\{"S":"Discontinued"\} \}
You could then use these values in an expression, such as this:
ProductStatus IN (:avail, :back, :disc)

#filter_expression ⇒ String
(rw)
A string that contains conditions that ::Aws::DynamoDB
applies after the
Scan
operation, but before the data is returned to you. Items that
do not satisfy the FilterExpression
criteria are not returned.
FilterExpression
is applied after the items have already been
read; the process of filtering does not consume any additional read
capacity units.

#index_name ⇒ String
(rw)
The name of a secondary index to scan. This index can be any local
secondary index or global secondary index. Note that if you use the

#limit ⇒ Integer
(rw)
The maximum number of items to evaluate (not necessarily the number
of matching items). If DynamoDB processes the number of items up to
the limit while processing the results, it stops the operation and
returns the matching values up to that point, and a key in
LastEvaluatedKey
to apply in a subsequent operation, so that you
can pick up where you left off. Also, if the processed dataset size
exceeds 1 MB before ::Aws::DynamoDB
reaches this limit, it stops the
operation and returns the matching values up to the limit, and a key
in LastEvaluatedKey
to apply in a subsequent operation to continue
the operation. For more information, see Working with Queries
in the Amazon ::Aws::DynamoDB
Developer Guide.

#projection_expression ⇒ String
(rw)
A string that identifies one or more attributes to retrieve from the specified table or index. These attributes can include scalars, sets, or elements of a JSON document. The attributes in the expression must be separated by commas.
If no attribute names are specified, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.

#return_consumed_capacity ⇒ String
(rw)
Determines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:
INDEXES
- The response includes the aggregateConsumedCapacity
for the operation, together withConsumedCapacity
for each table and secondary index that was accessed.
Note that some operations, such as GetItem
and BatchGetItem
,
do not access any indexes at all. In these cases, specifying
INDEXES
will only return ConsumedCapacity
information for
table(s).
TOTAL
- The response includes only the aggregateConsumedCapacity
for the operation.NONE
- NoConsumedCapacity
details are included in the response.

#segment ⇒ Integer
(rw)
For a parallel Scan
request, Segment
identifies an individual
segment to be scanned by an application worker.
Segment IDs are zero-based, so the first segment is always 0. For
example, if you want to use four application threads to scan a table
or an index, then the first thread specifies a Segment
value of 0,
the second thread specifies 1, and so on.
The value of LastEvaluatedKey
returned from a parallel Scan
request must be used as ExclusiveStartKey
with the same segment ID
in a subsequent Scan
operation.
The value for Segment
must be greater than or equal to 0, and less
than the value provided for TotalSegments
.
If you provide Segment
, you must also provide TotalSegments
.

#select ⇒ String
(rw)
The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.
ALL_ATTRIBUTES
- Returns all of the item attributes from the specified table or index. If you query a local secondary index, then for each matching item in the index, DynamoDB fetches the entire item from the parent table. If the index is configured to project all item attributes, then all of the data can be obtained from the local secondary index, and no fetching is required.ALL_PROJECTED_ATTRIBUTES
- Allowed only when querying an index. Retrieves all attributes that have been projected into the index. If the index is configured to project all attributes, this return value is equivalent to specifyingALL_ATTRIBUTES
.COUNT
- Returns the number of matching items, rather than the matching items themselves. Note that this uses the same quantity of read capacity units as getting the items, and is subject to the same item size calculations.SPECIFIC_ATTRIBUTES
- Returns only the attributes listed inProjectionExpression
. This return value is equivalent to specifyingProjectionExpression
without specifying any value forSelect
.
If you query or scan a local secondary index and request only attributes that are projected into that index, the operation reads only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB fetches each of these attributes from the parent table. This extra fetching incurs additional throughput cost and latency.
If you query or scan a global secondary index, you can only request attributes that are projected into the index. Global secondary index queries cannot fetch attributes from the parent table.
If neither Select
nor ProjectionExpression
are specified,
::Aws::DynamoDB
defaults to ALL_ATTRIBUTES
when accessing a table, and
ALL_PROJECTED_ATTRIBUTES
when accessing an index. You cannot use
both Select
and ProjectionExpression
together in a single
request, unless the value for Select
is SPECIFIC_ATTRIBUTES
.
(This usage is equivalent to specifying ProjectionExpression
without any value for Select
.)
ProjectionExpression
parameter, then the value for
Select
can only be SPECIFIC_ATTRIBUTES
. Any other value for
Select
will return an error.

(rw)
For a parallel Scan
request, TotalSegments
represents the total
number of segments into which the Scan
operation will be divided.
The value of TotalSegments
corresponds to the number of
application workers that will perform the parallel scan. For
example, if you want to use four application threads to scan a table
or an index, specify a TotalSegments
value of 4.
The value for TotalSegments
must be greater than or equal to 1,
and less than or equal to 1000000. If you specify a TotalSegments
value of 1, the Scan
operation will be sequential rather than
parallel.
If you specify TotalSegments
, you must also specify Segment
.

Contributors
Pandas implements some matplotlib converters for nicely formatting the axis labels on plots with datetime or Period values. Prior to pandas 0.21.0, these were implicitly registered with matplotlib, as a side effect of import pandas.
datetime
Period
import pandas
In pandas 0.21.0, we required users to explicitly register the converter. This caused problems for some users who relied on those converters being present for regular matplotlib.pyplot plotting methods, so we’re temporarily reverting that change; pandas 0.21.1 again registers the converters on import, just like before 0.21.0.
matplotlib.pyplot
We’ve added a new option to control the converters: pd.options.plotting.matplotlib.register_converters. By default, they are registered. Toggling this to False removes pandas’ formatters and restore any converters we overwrote when registering them (GH18301).
pd.options.plotting.matplotlib.register_converters
False
We’re working with the matplotlib developers to make this easier. We’re trying to balance user convenience (automatically registering the converters) with import performance and best practices (importing pandas shouldn’t have the side effect of overwriting any custom converters you’ve already set). In the future we hope to have most of the datetime formatting functionality in matplotlib, with just the pandas-specific converters in pandas. We’ll then gracefully deprecate the automatic registration of converters in favor of users explicitly registering them when they want them.
DataFrame.to_parquet() will now write non-default indexes when the underlying engine supports it. The indexes will be preserved when reading back in with read_parquet() (GH18581).

public interface Document
The Document
is a container for text that serves
as the model for swing text components. The goal for this
interface is to scale from very simple needs (a plain text textfield)
to complex needs (an HTML or XML document, for example).
Content
At the simplest level, text can be modeled as a linear sequence of characters. To support internationalization, the Swing text model uses unicode characters. The sequence of characters displayed in a text component is generally referred to as the component's content.
To refer to locations within the sequence, the coordinates used are the location between two characters. As the diagram below shows, a location in a text document can be referred to as a position, or an offset. This position is zero-based.
In the example, if the content of a document is the sequence "The quick brown fox," as shown in the preceding diagram, the location just before the word "The" is 0, and the location after the word "The" and before the whitespace that follows it is 3. The entire sequence of characters in the sequence "The" is called a range.
The following methods give access to the character data that makes up the content.
Structure
Text is rarely represented simply as featureless content. Rather, text typically has some sort of structure associated with it. Exactly what structure is modeled is up to a particular Document implementation. It might be as simple as no structure (i.e. a simple text field), or it might be something like diagram below.
The unit of structure (i.e. a node of the tree) is referred to by the Element interface. Each Element can be tagged with a set of attributes. These attributes (name/value pairs) are defined by the AttributeSet interface.
The following methods give access to the document structure.
Mutations
All documents need to be able to add and remove simple text. Typically, text is inserted and removed via gestures from a keyboard or a mouse. What effect the insertion or removal has upon the document structure is entirely up to the implementation of the document.
The following methods are related to mutation of the document content:
Notification
Mutations to the Document
must be communicated to
interested observers. The notification of change follows the event model
guidelines that are specified for JavaBeans. In the JavaBeans
event model, once an event notification is dispatched, all listeners
must be notified before any further mutations occur to the source
of the event. Further, order of delivery is not guaranteed.
Notification is provided as two separate events,
DocumentEvent, and
UndoableEditEvent.
If a mutation is made to a Document
through its api,
a DocumentEvent
will be sent to all of the registered
DocumentListeners
. If the Document
implementation supports undo/redo capabilities, an
UndoableEditEvent
will be sent
to all of the registered UndoableEditListener
s.
If an undoable edit is undone, a DocumentEvent
should be
fired from the Document to indicate it has changed again.
In this case however, there should be no UndoableEditEvent
generated since that edit is actually the source of the change
rather than a mutation to the Document
made through its
api.
Referring to the above diagram, suppose that the component shown on the left mutates the document object represented by the blue rectangle. The document responds by dispatching a DocumentEvent to both component views and sends an UndoableEditEvent to the listening logic, which maintains a history buffer.
Now suppose that the component shown on the right mutates the same document. Again, the document dispatches a DocumentEvent to both component views and sends an UndoableEditEvent to the listening logic that is maintaining the history buffer.
If the history buffer is then rolled back (i.e. the last UndoableEdit undone), a DocumentEvent is sent to both views, causing both of them to reflect the undone mutation to the document (that is, the removal of the right component's mutation). If the history buffer again rolls back another change, another DocumentEvent is sent to both views, causing them to reflect the undone mutation to the document -- that is, the removal of the left component's mutation.
The methods related to observing mutations to the document are:
Properties
Document implementations will generally have some set of properties
associated with them at runtime. Two well known properties are the
StreamDescriptionProperty,
which can be used to describe where the Document
came from,
and the TitleProperty, which can be used to
name the Document
. The methods related to the properties are:

To ensure reasonable behavior in the face
of concurrency, the event is dispatched after the
mutation has occurred. This means that by the time a
notification of removal is dispatched, the document
has already been updated and any marks created by
createPosition
have already changed.
For a removal, the end of the removal range is collapsed
down to the start of the range, and any marks in the removal
range are collapsed down to the start of the range.
If the Document structure changed as result of the removal, the details of what Elements were inserted and removed in response to the change will also be contained in the generated DocumentEvent. It is up to the implementation of a Document to decide how the structure should change in response to a remove.

If the partialReturn property on the txt parameter is false, the data returned in the Segment will be the entire length requested and may or may not be a copy depending upon how the data was stored. If the partialReturn property is true, only the amount of text that can be returned without creating a copy is returned. Using partial returns will give better performance for situations where large parts of the document are being scanned. The following is an example of using the partial return to access the entire document:
int nleft = doc.getDocumentLength();
Segment text = new Segment();
int offs = 0;
text.setPartialReturn(true);
while (nleft > 0) {
doc.getText(offs, nleft, text);
// do someting with text
nleft -= text.count;
offs += text.count;
}

Typically there will be only one document structure, but the interface supports building an arbitrary number of structural projections over the text data. The document can have multiple root elements to support multiple document structures. Some examples might be:

Frequentist inference is the process of determining properties of an underlying distribution via the observation of data.
One of the main goals of statistics is to estimate unknown parameters. To approximate these parameters, we choose an estimator, which is simply any function of randomly sampled observations.
To illustrate this idea, we will estimate the value of \( \pi \) by uniformly dropping samples on a square containing an inscribed circle. Notice that the value of \( \pi \) can be expressed as a ratio of areas. $$\begin{matrix}S_{circle} = \pi r^2\\S_{square} = 4r^2\end{matrix} \implies \pi = 4 \frac{S_{circle}}{S_{square}}$$ We can estimate this ratio with our samples. Let \( m \) be the number of samples within our circle and \( n \) the total number of samples dropped. We define our estimator \( \hat{\pi} \) as: $$\hat{\pi} = 4 \frac{m}{n}$$ It can be shown that this estimator has the desirable properties of being unbiased and consistent.
|
\( m= \) 0.00 \( n= \) 0.00 |
\( \hat{\pi}= \) |
In contrast to point estimators, confidence intervals estimate a parameter by specifying a range of possible values. Such an interval is associated with a confidence level, which is the probability that the procedure used to generate the interval will produce an interval containing the true parameter.
Choose a probability distribution to sample from.
Choose a sample size \((n)\) and confidence level \((1-\alpha)\).
Start sampling to generate confidence intervals.
This visualization was adapted from Kristoffer Magnusson's fantastic visualization of confidence intervals.
Much of frequentist inference centers on the use of "good" estimators. The precise distributions of these estimators, however, can often be difficult to derive analytically. The computational technique known as the Bootstrap provides a convenient way to estimate properties of an estimator via resampling. In this example, we resample with replacement from the empirical distribution function (which is itelf generated by sampling once from the population) in order to estimate the standard error of the sample mean.
Choose a probability distribution from which we will sample once to generate the empirical distribution function.
Choose a sample (and resampling) size \((n)\) and sample from your chosen distribution.
Resample to get an idea of the spread of the sample mean's distribution.

话说，第二次工业革命时期，科学技术发展突飞猛进，新技术新发明层出不穷，工厂生产规模不断发展。相应的，对现代科学管理提出了更高的要求。这一时期涌现了一批研究管理方法的学者。比如有精准分析工人作业动作的 Frank
Gilbreth，他把工人的标准操作分解为所谓 Therblig 的 17 个动作，然后用秒表进行计时进行动作优化。
照理说，把动作结构、优化、再组合，工人的工作效率应该很高才对。可是，事实正好相反，反而是，越来越多的工人们消极怠工。这时候，有个叫 Frederick
Winslow Taylor 的人跳出来，说要解决这个问题。他后来被成为科学管理之父。在钢铁厂工作的时候，泰勒发现很多工人通过破坏工具等方法，故意降低生产效率。他将这种蓄意的工人们消极怠工、摸鱼、磨洋工的行为称为 soldiering：
Tayler witnessed many acts aimed at limiting or reducing production —
including having his tools destroyed — and it was he who coined the
term soldiering to describe this deliberate act. Working in the steel
industry, Taylor had observed the phenomenon of workers’ purposely
operating well below their capacity, that is, soldiering. He
attributed soldiering to three causes :
- The almost universally held belief among workers that if they became more productive, fewer of them would be needed and jobs would be eliminated.
- Non-incentive wage systems encourage low productivity if the
employee will receive the same pay regardless of how much is
produced, assuming the employee can convince the employer that the
slow pace really is a good pace for the job. Employees take great
care never to work at a good pace for fear that this faster pace
would become the new standard. If employees are paid by the quantity
they produce, they fear that management will decrease their per-unit
pay if the quantity increases.
- Workers waste much of their effort by relying on rule-of-thumb
methods rather than on optimal work methods that can be determined
by scientific study of the task.
他总结了工人之所以会 soldiering 的三个原因：
- 工人普遍认为，工作太积极，活儿会干完，大家会失业。
- 当时的薪酬系统不奖励工作效率的提升，工人担心太快地干活，会成为新的工作标准
- 工作方法多以经验为主，没有进行科学的优化
相应的，泰勒提出了科学管理的四个原则：
- 针对生产任务，以科学分析的方法替代经验判断
- 科学系统的选择培训员工而不是放任不管
- 协调工人们使用科学的工作方法
- 协调管理层和工人进行工作分配，互相支持，合理激励

■German Shepherds are medium to large-sized dogs.
■ The breed standard height at the withers is 60–65 cm (24–26 in) for males, and 55–60 cm (22–24 in) for females.
■German Shepherds are longer than they are tall, with an ideal proportion of 10 to 81⁄2.
■They have a domed forehead, a long square-cut muzzle with strong jaws and a black nose.
■The eyes are medium-sized and brown.
■The ears are large and stand erect, open at the front and parallel, but they often are pulled back during movement. A German Shepherd has a long neck, which is raised when excited and lowered when moving at a fast pace.
■Intelligence: ●German Shepherds were bred specifically for their intelligence. Coupled with their strength,this trait makes the breed desirable as police, guard and search and rescue dogs as they are able to quickly learn various tasks and interpret instructions better than other breeds.
■Temperament: ●German Shepherds are moderately active dogs and are described in breed standards as self assured.
■USE AS WORKING DOG : ●German Shepherds are a popular selection for use as WORKING DOG.
■Body: The body should have a powerful and muscular build.
■CHARACTERISTICS : ●They are especially well known for their POLICE WORK being used for tracking criminals, patrolling troubled areas and detection and holding of suspects. Additionally, thousands of German Shepherds have been used by the military.
■FOOD HABIT: ●Meat - 50%-70% content and should be low fat.
●Baked or boiled meat is the ideal food for a German Shepherd.
●Raw meaty bones, eggs.
●Cooked fish; pink salmon,trout,sardines, and jack mackerel.
●Organs such as liver should be included in the diet in a small quantity.
■HEALTH: ●Many common ailments of the German Shepherd are a result of the inbreeding practiced early in the breed's life.
●One such common ailment is HIP and ELBOW DYSPLASIA which may cause the dog to experience pain later on in life and may cause ARTHRITIS.


Derbyshire house with huge garden up for auction for just £55k - but it needs some work
A perfect opportunity for someone to invest in
by Hayley WatsonA Derbyshire home could be snapped up for a bargain price at auction next month.
The end of terrace house in Swadlincote has been listed for auction with SDL Auctions - with a starting price of just £55,000.
According to Rightmove, the average price of semi-detached properties sold in the town over the past year was £160,833.
The 'larger-than-average' property could make an ideal family home, with a generously-sized garden, offering the potential for an extention.
However, pictures show it will require some improvement before anyone moves in.
In an online listing for the property, the auctioneers say: "Requiring some improvement and upgrading is a larger than average two double bedroomed end-terraced property with the advantage of a driveway to the side and potential for an extension (subject to planning consent).
"Internally the property has the benefit of gas central heating and is mostly double glazed and in brief comprises generous sized lounge through diner measuring 27'6" x 13'5", fitted kitchen and walk-in pantry."
It continues: "To the first floor the passaged leads to two genuine double bedrooms and a spacious bathroom with three piece suite and shower.
"Outside there is a driveway to the side leading to a good sized enclosed garden enjoying a southerly aspect.
"The property is situated in the context of an established residential location always popular with first time buyers, young families and landlords.
"Swadlincote town centre is a short commute along with Burton town centre. Excellent freehold investment opportunity."
If a bit of home decor doesn't put you off, 78 Regent Street will feature in SDL Auction's upcoming event in Derby on December 13.
The auction takes place at The Pedigree Suite at Pride Park Stadium, starting at 11:30am.


COMING UP ROSES A film review by Jeff Meyer Copyright 1987 Jeff Meyer
Seen at the Seattle Film Festival: COMING UP ROSES (Great Britain, 1986) Director: Stephen Bayly Screenwriter: Ruth Carter Cast: David Hywel, Iola Gregory, Olive Michael, Mari Emlyn Subtitled
This is certainly one of the more unusual films to come along during the festival--a foreign language film shot in the heart of England. In other words, the film is about a community in Wales, and (properly) the actors speak in Welsh, with English subtitles. The story is reminiscent of the older Ealing comedies of the 1950s--it has the uniquely British low-key humor that permeated so many of Alec Guinness's and Peter Sellers's early films. It tells the story of the employees of an old movie theatre, the last of five in a Welsh mining village that is slowly dying from lack of work. The elderly owner is forced to sell it to a holding company, and the projectionist, a wonderfully honest character who has never wanted to do anything but show movies, is forced to find work elsewhere, along with the plucky concessions woman. As they both vainly try to find a job that they think is responsible, and watch their hopes of seeing the theatre refurbished and returned to its former glory die, they become more morose, until they come up with a scheme involving the vacant theatre with what they hope will allow them to make an "honorable living." This, a budding romance, some of the unlikeliest people you could mention, and the old theatre owner's last wish make for an excellent bit of drollery which fans of films like A PRIVATE FUNCTION should enjoy.
The director of the film appeared afterwards, and I admit that I enjoyed his discussion of the making of the film almost as much as the film itself. It turns out that the theatre that they used for the film was, in fact, abandoned and about to be torn down--it had been bought by the local bingo parlor so that it wouldn't provide competition. However, members of the town, in conjunction with the director, came together to get the theatre restored, and it is back in business, providing entertainment for a community where economic depression is a way of life. It is the first film ever made in Welsh, a project initiated by a government grant to create television and films for the Welsh audience. He wanted to make a film that reflected the "Welsh 'toughness of spirit'" that keeps their dignity and sense of humor in the face of intimidating day-to-day living conditions. In that, I think he has succeeded; this is both an amusing and affectionate tribute to this country.
GRADE: B for British understated humor buffs; may be less appealing to those who prefer Benny Hill to Bill Forsythe.

Given the choice between WW1 and WW2, most people would would think that WW2 was more impactful on our world today. However, WW1 created the league of nations, Brought in the use of chemical warfare only to limit its usage, dismissed the world's romanticized views on war , and created the longest lasting terms for a treaty in modern history.

In the previous sections, we set up the Meiosis pattern with function patches, and with Mergerino. In both cases, we created:
states
: a stream of application statesupdate
: a stream of updates to the application stateWe now have a way to manage application state. The next part of the pattern will be to wire up the application state to a view library. We will be looking at that in the next section. Before doing that, however, let's discuss a small but useful detail.
As it is now, we would need to pass states
-- or rather, states()
, that is, the current state --
and update
to our views. Views would have to pass them along to other views.
To make things simpler, let's pass a single parameter to our views.
I chose the name cell because in science, Meiosis has to do with cells.
Passing a single cell
parameter to our views makes it simpler later on to refactor if we want to
pass additional properties besides the current state and the update stream. We can add the
properties to the cell, and we won't have to change the parameters in all of our views.
We can also pass cell
to actions, making it easy for actions to access the current state and issue
updates.
Creating a stream of cells from the stream of states is simple. We can use map
:
const update = flyd.stream();
const createCell = (state) => ({ state, update });
const cells = states.map(createCell);
We now have a stream of cells. To get the current cell, we can call cells()
and pass that as a
cell
to views. Views can then access the state with cell.state
and issue updates by calling
cell.update(...)
. Finally, we can also pass cell
to actions which in turn can use cell.state
and cell.update(...)
.
In the following section, we will look at how to wire up the Meiosis pattern to three view libraries.

Aims & Scope Advisory Board Constitution DOAJ Team Partnerships
The Directory of Open Access Journals was launched in 2003 at Lund University, Sweden, with 300 open access journals and today contains more than 10000 open access journals covering all areas of science, technology, medicine, social science and humanities.
DOAJ is a membership organisation and membership is available in 3 main categories: Publisher, Ordinary Member and Sponsor. A DOAJ Membership is a clear statement of intent and proves a commitment to quality, peer-reviewed open access. DOAJ is co-author to the Principles of Transparency and Best Practice in Scholarly Publishing (Principles) and DOAJ members are expected to follow these principles as a condition of membership. DOAJ reserves the right to reject applications for membership, or revoke membership if a member or sponsor is found to contravene the Principles. Read more about membership here.
DOAJ is a white list of open access journals and aims to be the starting point for all information searches for quality, peer reviewed open access material. To assist libraries and indexers keep their lists up-to-date, we make public a list of journals that have been accepted into or removed from DOAJ but we will not discuss the details of an application with anyone apart from the applicant. Neither will we discuss individual publishers or applications with members of the public unless we believe that, by doing so, we will be making a positive contribution to the open access community.
DOAJ publishes Information for Publishers on this site to help Publishers to adhere to the Principles and to assist them in completing an application. DOAJ also publishes a list of FAQs relevant to all members of the publishing community, particularly libraries and authors. All information on this site is available to both members and non-members.
The aim of the DOAJ is to increase the visibility and ease of use of open access scientific and scholarly journals, thereby promoting their increased usage and impact. The DOAJ aims to be comprehensive and cover all open access scientific and scholarly journals that use a quality control system to guarantee the content. In short, the DOAJ aims to be the one-stop shop for users of open access journals.
DOAJ is a not-for-profit organisation managed by Infrastructure Services for Open Access C.I.C. (Community Interest Company) based in the United Kingdom. DOAJ relies entirely on the voluntary donations of its members and on sponsorship monies received. Currently, neither DOAJ or IS4OA receives grants or funding from any other source.
DOAJ has an Advisory Board, the members of which carry out their duties voluntarily.
DOAJ uses the services of approximately 100 voluntary editorial staff who review applications. Volunteers are bound by a Code of Conduct and an Agreement that they must sign and return to DOAJ before they can carry out their duties. At least two references are requested from everyone who volunteers and all volunteers are bound by the Code of Conduct to declare any conflicts of interest to the Managing Editors.

13.22. Release 0.220
General Changes
- Fix an issue where spatial joins executed after right outer joins would fail in certain cases. See #12672.
- Fix an issue where
TRY
cannot catch the failures in ROW
comparisons with NULL
fields and ARRAY
comparisons with NULL
elements.
- Improve scan performance for queries that read map columns but do not access individual keys.
Raptor Changes
- Add support for writing files with
ZSTD
compression. Add configuration property storage.orc.compression-kind
to switch between SNAPPY
and ZSTD
.
This is only applied when optimized ORC writer is turned on.
- Improve performance of the ORC writer in Raptor. Add configuration property
storage.orc.optimized-writer-stage
to enable the performance enhancement.
The optimized ORC writer is backward compatible with the Hadoop ORC writer, but the Hadoop ORC writer is not forward compatible with it.
Turning on the optimized ORC writer should work on an existing Raptor server. However, switching back to the Hadoop ORC writer may fail Raptor background job.
Hive Connector Changes
- Add
compression_codec
session property to set the compression codec when writing files. Possible values are NONE
, SNAPPY
, and GZIP
.
- Add experimental support for partial merge pushdown, which optimizes plans for queries joining over two tables with mismatched but compatible bucket counts.
This feature can be enabled by session property
experimental.optimizer.partial-merge-pushdown-strategy
, and is aiming to supersede hive.optimize-mismatched-bucket-count
.
See #12611.
- Improve query performance when writing bucketed tables.
MongoDB Connector Changes
- Add
mongodb.read-preference-tags
configuration property to configure mongodb read preference tags.
Tag sets are separated by an ampersand, and each tag set is specified as a comma-separated list of colon-separated key-value pairs.
For example, mongodb.read-preference-tags=dc:east,use:reporting&use:reporting
.
JDBC Driver Changes
- Fix incorrect precision and column display size in
ResultSetMetaData
for CHAR
and VARCHAR
columns.
Verifier Changes
- Fix an issue where Verifier would always mark floating point columns as mismatched if either the control checksum or test checksum was 0 while the other was close to 0.
Add configuration property
absolute-error-margin
to configure this threshold.
- Fix error messages for floating point column mismatches.
- Add configuration property
failure-resolver.enabled
to allow automatic failure resolution be disabled.
- Add control and test checksum query IDs to Verifier output event.
- Improve Presto query retries by allowing Verifier to recognize
JdbcErrorCode
and ThriftErrorCode
,
and by marking ABANDONED_TASK
, HIVE_WRITER_OPEN_ERROR
, JDBC_ERROR
, and THRIFT_SERVICE_CONNECTION_ERROR
as retryable errors.
SPI Changes
- Move
FunctionMetadata
to SPI.
- Add
FunctionMetadataManager
and StandardFunctionResolution
in ConnectorContext
.
The two interfaces allow connectors to obtain the metadata of a Presto system function as well as to resolve standard functions, such as add, minus, and, or, etc.
- Remove
distributedPlanningTime
from QueryStatistics
- Remove redundant offset parameter in
Block#getByte
, Block#getShort
, and Block#getInt
.


During the time I was working on the kata, I came across a lot of problems. I've come to realize that some of them
were small problems. The one mentionable problem was during an exercise where I needed to create a collection of
elements called an object. All I had to do was use two little symbols "{}" which indicates the creation of an object
and then place my elements in them e.g. name, age, and so on. I thought about it for a while, even going through
previous exercises and I Googled "How to return an object". When I looked at the solution I couldn't believe that
I slipped on something so simple...
There are many listed ways of problem solving:
Pseudocode, trying something, Rubber Ducky Method, Reading error messages, Console.logging, Googling,
Asking peers, Asking coaches, Improving by reflecting, and so on.
I'm still working through the error message method but at the very least I can decipher where my problem
is, and for the most part, what's missing. The only problem I have with asking peers or coaches is sometimes
they aren't available and not everyone is in the position to help. I'm a bit of a weirdo so talking to myself or
at
the wall/inanimate object has always been a problem solving method for everything. The most fun is just
trying
things and seeing what they do and seeing how I can use them to solve my problem.
I solved a problem that involved taking a statement that was written backwards, and putting it the right
way.
The smoothness of thought when solving this problem was just such a big moment for me. I'm not
saying I'm good at
coding. Nowhere near, but my thought process was extremely clear solving this one.
First, I remembered that there was a method that allowed me to seperate a statement into a list of
individual words called the .split method. I then thought, how can I reverse the order and, at the same
time reverse the words themselves. Turns out there's a method called the .reverse method. And then
straight away,
I remembered that in a previous exercise I practiced putting words and statements
together using the
.join method.
Hopefully comes a time where I have enough experience that moments of clicking together like this
happens more often but that was an elegant and smooth way of solving that particular problem.
