BLUSH (HONG FEN) A film review by James Berardinelli Copyright 1996 James Berardinelli
RATING (0 TO 10): 6.0 Alternative Scale: **1/2 out of ****
China, 1994 U.S. Release Date: widely variable (limited) Running Length: 2:00 MPAA Classification: No MPAA Rating (Mature themes, sex) Theatrical Aspect Ratio: 1.66:1
Cast: Ji Wang, Zhiwen Wang, Caifei He Director: Shaohong Li Producer: Zhigu Cheng, Chen Kunming, Yi Liu, Jimmy Tan Screenplay: Ni Zhen and Shaohong Li based on the novel by Su Tong Cinematography: Nianping Zeng Music: Wenjing Guo U.S. Distributor: First Run Features In Chinese with subtitles
Many Chinese films exported during the past half-decade (or so) have shared a fondness for tragic melodrama. Titles such as JU DOU, RAISE THE RED LANTERN, FAREWELL MY CONCUBINE, TEMPTATION OF A MONK, TO LIVE, and SHANGHAI TRIAD all end bleakly. This isn't necessarily a bad thing (in fact, some of the above movies are excellent), but it creates certain expectations when viewing a motion picture originating from Mainland China. To a large extent, BLUSH delivers what we anticipate, although the ending isn't as joyless as those of its many predecessors.
BLUSH takes us back to the Communist "Liberation" of 1949, when Chairman Mao stormed into power and swept away the decadent old ways. Landowners' property was seized for distribution, wealth was confiscated, and those holding unproductive jobs were placed into "rehabilitation centers" to learn how to become workers. Unlike many of the movies that came before it (such as TO LIVE and FAREWELL MY CONCUBINE), BLUSH doesn't have a cynical or negative perspective of the Liberation. Shaohong Li, directing from a script based on a book by Su Tong (who also wrote the novel RAISE THE RED LANTERN), views these events as historical facts that form the backdrop for a story, not an opportunity for a political statement. Her depiction of the revolution and its aftermath is evenhanded.
The film opens as the prostitutes from the Red Happiness Inn in Shanghai are being herded like sheep into a re-training center. In the group are the strong-willed Qiuyi (Ji Wang), who refuses to go quietly, and her meek friend, Xiao'e (Caifei He). During the inevitable confusion caused by detaining so many women, Qiuyi escapes, then makes her way to the house of a wealthy former customer, Lao Pu (Zhiwen Wang), who takes her in as his mistress. Eventually, Lao's mother complains, and a pregnant Qiuyi is forced to leave. She goes to a nearby convent for sanctuary. Meanwhile, after being properly re-educated, Xiao'e, now a loyal worker, begins to spend time with Lao Pu. Her goal isn't subtle -- she wants to marry him.
Despite the subtitles, scrupulously accurate period details, and strong acting, BLUSH is basically a cinematic soap opera. There are betrayals, attempted suicides, unplanned pregnancies, tearful confessions, and jealous suspicions. All of these things take place in the shadow of the central love triangle between Lao Pu; his true love, Qiuyi; and the woman he marries, Xiao'e. Disappointingly, however, many of the most important events are not shown, but are instead related via a voiceover narration. This fundamentally unsatisfying method of presentation undercuts the film's dramatic power. The ending is especially weak because a key aspect of the denouement is described, but never depicted.
BLUSH's primary message is that, to survive, people can adapt to any situation. Like social chameleons, Qiuyi and Xiao'e are constantly changing. Qiuyi is transformed from a glamorous prostitute to a pampered mistress to a Buddhist nun to a humbled mother. For Xiao'e, the final destination is the same, but, because she is less stubborn and more manipulative, her route is less turbulent.
Really, it's the historical context that makes this movie worthwhile, although primarily for those with interest in the era. There's nothing remarkable about the storyline, and the tear-jerking is only marginally successful. Nevertheless, the movie affords us another perspective of a period in modern Chinese history that has already received much film exposure. BLUSH is well-paced and moderately entertaining, but it lacks the depth which has characterized many other, recent exports from that part of the world. Sadly, this basic deficiency makes for a largely unmemorable motion picture.

announcing free Orgs
Today, we’re excited to announce that npm Orgs, our collaboration tool for helping teams manage permissions and share their code, is free for all developers of open source packages. You may invite an unlimited number of collaborators to manage an unlimited number of public packages for $0.
We launched Orgs in 2015 for companies that needed to mix public and private code. They wanted an easy way to set permissions for multiple team members and multiple packages. Now, teams who don’t need private packages can use this functionality too.
Why would we give away our most popular product? Making it easier to collaborate on open source projects is good for the whole community, and anything that reduces friction makes it easier for everyone to build amazing things.
Take a look at our Orgs docs to learn how these work, and create a free Org now to supercharge how you collaborate on development projects.
If you run into any questions, just drop a line to our support team at<EMAIL_ADDRESS>or tweet us @npmjs. We can’t wait to see what you build.


 I come from a really small town. I knew drugs existed but I never really saw them...well except pot which was grown all over. I found out a close friend of mine was heavy into crank and I always lectured her. But one day a long time after I learned she was using. I decided to use it myself because of the incredible high I learned it gave you and I was kinda wondering what it would be like and if it would be better than weed.
I thought I could do it and not become addicted. Well I tried it and loved it. I loved it! I kept doing it here and there and before I knew it I was doing it everyday. Every thing seemed to be going wrong in my life and crank seemed to make it better. My grandpa died last november.....I went to his memorial service spun out of my mind. I was going to school and working. Those got boring for me real quick. Pretty soon my mission in life was to get high. Me and my roomates would spend everyday searching for a quarter and smoke it (occasionally snort it but smoking it was our favorite). We never ever fought until we started doing crank.  It got to the point where we were scraping straws and bags and then licking them.
One night I had been up for almost 4 days and went to this party....smoked some more and did a little weed to come home and was completely paranoid. I swore there were people chanting and trying to get in my house. I thought they were out to get me. I was becoming so paranoid. This didn't only happen once but many times. Not as bad as that night of course. But I would be laying in bed trying to sleep and scared out of my mind that people would break in and kill us. I would alwasy be looking out the window. Finally I moved away just a couple of months ago. Here I don't know anyone and am living with my father who is a preacher. I don't have access to it. I could get it if I wanted it bad enough. But I know what it does to you.
But everyday I think about it. I know if it was in front of me I would do it in a minute. I crave it like crazy. As much as I know it is bad for you....I still want it. I am waiting for that to go away but I am afraid it never will. Whenever I did not have it for a few days or like the past few months. All I did was sleep and eat. I can not believe how much I slept. I went back and looked at all the effects and withdrawal sypmtoms and have been amazed and scared that some white powder has so much control over me.
I want out .....but I want more too. It is crazy to get started but once you do....It is hard to get out of it. It gives you such an incredible feeling that you think that nothing could be bad about it until you don't have it anymore or you have been doing it so long that it is the only thing you can think about and your life is in shambles. I don't suggest anyone to try it but I don't look down on those who can't seem to stop because I know how that feels. The key is to stop being around those who do it too. Once I did it, it was like entering a club. You suddenly know people who do it that you would have never thought and you can pick people out who do it and this is still when you quit. Save yourself and don't try or at least try not to.

“And send the godly in a pet to pray.”—POPE.
ARGUMENT.—Holy Willie was a rather oldish bachelor elder, in the parish of Mauchline, and much and justly famed for that polemical chattering, which ends in tippling orthodoxy, and for that spiritualized bawdry which refines to liquorish devotion. In a sessional process with a gentleman in Mauchline—a Mr.Gavin Hamilton—Holy Willie and his priest, Father Auld, after full hearing in the presbytery of Ayr, came off but second best; owing partly to the oratorical powers of Mr. Robert Aiken, Mr. Hamilton’s counsel; but chiefly to Mr. Hamilton’s being one of the most irreproachable and truly respectable characters in the county. On losing the process, the muse overheard him [Holy Willie] at his devotions, as follows:—
O THOU, who in the heavens does dwell,
Who, as it pleases best Thysel’,
Sends ane to heaven an’ ten to hell,
A’ for Thy glory,
And no for ony gude or ill
They’ve done afore Thee!
I bless and praise Thy matchless might,
When thousands Thou hast left in night,
That I am here afore Thy sight,
For gifts an’ grace
A burning and a shining light
To a’ this place.
What was I, or my generation,
That I should get sic exaltation,
I wha deserve most just damnation
For broken laws,
Five thousand years ere my creation,
Thro’ Adam’s cause?
When frae my mither’s womb I fell,
Thou might hae plunged me in hell,
To gnash my gums, to weep and wail,
In burnin lakes,
Where damned devils roar and yell,
Chain’d to their stakes.
Yet I am here a chosen sample,
To show thy grace is great and ample;
I’m here a pillar o’ Thy temple,
Strong as a rock,
A guide, a buckler, and example,
To a’ Thy flock.
O L—d, Thou kens what zeal I bear,
When drinkers drink, an’ swearers swear,
An’ singin there, an’ dancin here,
Wi’ great and sma’;
For I am keepit by Thy fear
Free frae them a’.
But yet, O L—d! confess I must,
At times I’m fash’d wi’ fleshly lust:
An’ sometimes, too, in wardly trust,
Vile self gets in:
But Thou remembers we are dust,
Defil’d wi’ sin.
O L—d! yestreen, Thou kens, wi’ Meg—
Thy pardon I sincerely beg,
O! may’t ne’er be a livin plague
To my dishonour,
An’ I’ll ne’er lift a lawless leg
Again upon her.
Besides, I farther maun allow,
Wi’ Leezie’s lass, three times I trow—
But L—d, that Friday I was fou,
When I cam near her;
Or else, Thou kens, Thy servant true
Wad never steer her.
Maybe Thou lets this fleshly thorn
Buffet Thy servant e’en and morn,
Lest he owre proud and high shou’d turn,
That he’s sae gifted:
If sae, Thy han’ maun e’en be borne,
Until Thou lift it.
L—d, bless Thy chosen in this place,
For here Thou hast a chosen race:
But G—d confound their stubborn face,
An’ blast their name,
Wha bring Thy elders to disgrace
An’ public shame.
L—d, mind Gaw’n Hamilton’s deserts;
He drinks, an’ swears, an’ plays at cartes,
Yet has sae mony takin arts,
Wi’ great and sma’,
Frae G—d’s ain priest the people’s hearts
He steals awa.
An’ when we chasten’d him therefor,
Thou kens how he bred sic a splore,
An’ set the warld in a roar
O’ laughing at us;—
Curse Thou his basket and his store,
Kail an’ potatoes.
L—d, hear my earnest cry and pray’r,
Against that Presbyt’ry o’ Ayr;
Thy strong right hand, L—d, make it bare
Upo’ their heads;
L—d visit them, an’ dinna spare,
For their misdeeds.
O L—d, my G—d! that glib-tongu’d Aiken,
My vera heart and flesh are quakin,
To think how we stood sweatin’, shakin,
An’ p—’d wi’ dread,
While he, wi’ hingin lip an’ snakin,
Held up his head.
L—d, in Thy day o’ vengeance try him,
L—d, visit them wha did employ him,
And pass not in Thy mercy by ’em,
Nor hear their pray’r,
But for Thy people’s sake, destroy ’em,
An’ dinna spare.
But, L—d, remember me an’ mine
Wi’ mercies temp’ral an’ divine,
That I for grace an’ gear may shine,
Excell’d by nane,
And a’ the glory shall be thine,
Amen, Amen!
HERE Holy Willie’s sair worn clay
Taks up its last abode;
His saul has ta’en some other way,
I fear, the left-hand road.
Stop! there he is, as sure’s a gun,
Poor, silly body, see him;
Nae wonder he’s as black’s the grun,
Observe wha’s standing wi’ him.
Your brunstane devilship, I see,
Has got him there before ye;
But haud your nine-tail cat a wee,
Till ance you’ve heard my story.
Your pity I will not implore,
For pity ye have nane;
Justice, alas! has gi’en him o’er,
And mercy’s day is gane.
But hear me, Sir, deil as ye are,
Look something to your credit;
A coof like him wad stain your name,
If it were kent ye did it.

The clachan yill had made me canty,
I was na fou, but just had plenty;
I stacher’d whiles, but yet too tent aye
To free the ditches;
An’ hillocks, stanes, an’ bushes, kenn’d eye
Frae ghaists an’ witches.
The rising moon began to glowre
The distant Cumnock hills out-owre:
To count her horns, wi’ a my pow’r,
I set mysel’;
But whether she had three or four,
I cou’d na tell.
I was come round about the hill,
An’ todlin down on Willie’s mill,
Setting my staff wi’ a’ my skill,
To keep me sicker;
Tho’ leeward whiles, against my will,
I took a bicker.
I there wi’ Something did forgather,
That pat me in an eerie swither;
An’ awfu’ scythe, out-owre ae shouther,
Clear-dangling, hang;
A three-tae’d leister on the ither
Lay, large an’ lang.
Its stature seem’d lang Scotch ells twa,
The queerest shape that e’er I saw,
For fient a wame it had ava;
And then its shanks,
They were as thin, as sharp an’ sma’
As cheeks o’ branks.
“Guid-een,” quo’ I; “Friend! hae ye been mawin,
When ither folk are busy sawin!”
I seem’d to make a kind o’ stan’
But naething spak;
At length, says I, “Friend! whare ye gaun?
Will ye go back?”

“Sax thousand years are near-hand fled
Sin’ I was to the butching bred,
An’ mony a scheme in vain’s been laid,
To stap or scar me;
Till ane Hornbook’s ta’en up the trade,
And faith! he’ll waur me.
“Ye ken Hornbook i’ the clachan,
Deil mak his king’s-hood in spleuchan!
He’s grown sae weel acquaint wi’ Buchan
And ither chaps,
The weans haud out their fingers laughin,
An’ pouk my hips.
“See, here’s a scythe, an’ there’s dart,
They hae pierc’d mony a gallant heart;
But Doctor Hornbook, wi’ his art
An’ cursed skill,
Has made them baith no worth a f—t,
D—n’d haet they’ll kill!
“’Twas but yestreen, nae farther gane,
I threw a noble throw at ane;
Wi’ less, I’m sure, I’ve hundreds slain;
But deil-ma-care,
It just play’d dirl on the bane,
But did nae mair.
“Hornbook was by, wi’ ready art,
An’ had sae fortify’d the part,
That when I looked to my dart,
It was sae blunt,
Fient haet o’t wad hae pierc’d the heart
Of a kail-runt.
“I drew my scythe in sic a fury,
I near-hand cowpit wi’ my hurry,
But yet the bauld Apothecary
Withstood the shock;
I might as weel hae tried a quarry
O’ hard whin rock.
“Ev’n them he canna get attended,
Altho’ their face he ne’er had kend it,
Just —— in a kail-blade, an’ sent it,
As soon’s he smells ’t,
Baith their disease, and what will mend it,
At once he tells ’t.
“And then, a’ doctor’s saws an’ whittles,
Of a’ dimensions, shapes, an’ mettles,
A’ kind o’ boxes, mugs, an’ bottles,
He’s sure to hae;
Their Latin names as fast he rattles
As A B C.
“Calces o’ fossils, earths, and trees;
True sal-marinum o’ the seas;
The farina of beans an’ pease,
He has’t in plenty;
Aqua-fontis, what you please,
He can content ye.
“Forbye some new, uncommon weapons,
Urinus spiritus of capons;
Or mite-horn shavings, filings, scrapings,
Distill’d per se;
Sal-alkali o’ midge-tail clippings,
And mony mae.”
“Waes me for Johnie Ged’s-Hole now,”
Quoth I, “if that thae news be true!
His braw calf-ward whare gowans grew,
Sae white and bonie,
Nae doubt they’ll rive it wi’ the plew;
They’ll ruin Johnie!”
The creature grain’d an eldritch laugh,
And says “Ye needna yoke the pleugh,
Kirkyards will soon be till’d eneugh,
Tak ye nae fear:
They’ll be trench’d wi’ mony a sheugh,
In twa-three year.
“Whare I kill’d ane, a fair strae-death,
By loss o’ blood or want of breath
This night I’m free to tak my aith,
That Hornbook’s skill
Has clad a score i’ their last claith,
By drap an’ pill.
“An honest wabster to his trade,
Whase wife’s twa nieves were scarce weel-bred
Gat tippence-worth to mend her head,
When it was sair;
The wife slade cannie to her bed,
But ne’er spak mair.
“A country laird had ta’en the batts,
Or some curmurring in his guts,
His only son for Hornbook sets,
An’ pays him well:
The lad, for twa guid gimmer-pets,
Was laird himsel’.
“A bonie lass—ye kend her name—
Some ill-brewn drink had hov’d her wame;
She trusts hersel’, to hide the shame,
In Hornbook’s care;
Horn sent her aff to her lang hame,
To hide it there.
“That’s just a swatch o’ Hornbook’s way;
Thus goes he on from day to day,
Thus does he poison, kill, an’ slay,
An’s weel paid for’t;
Yet stops me o’ my lawfu’ prey,
Wi’ his d—n’d dirt:
“But, hark! I’ll tell you of a plot,
Tho’ dinna ye be speakin o’t;
I’ll nail the self-conceited sot,
As dead’s a herrin;
Neist time we meet, I’ll wad a groat,
He gets his fairin!”
But just as he began to tell,
The auld kirk-hammer strak the bell
Some wee short hour ayont the twal’,
Which rais’d us baith:
I took the way that pleas’d mysel’,
And sae did Death.

class
TSA.merging.AGNES.
AGNES
(features, join_by='max')¶ Clusters the given feature vectors by the AGNES algorithm
AGNES(features, join_by=’max’)
Parameters: - features (2d numpy array) – The features to cluster by with dimensions (n_samples, n_features). It is advised to input features with normalised distributions as they are not scaled here and this is a distance based clustering algoithm
- join_by (string (optional)) –
The method by which to recalculate distance to a new group after merging occures. Allowed options are:
- ’max’ takes the new clusters distance as the maximum of either of the joined vectors distances
- ’min’ same as above but with minimum distance
-
cluster_by_derivative
(n_std=3.0, plot=True)¶ Find the grouping by allowing all mergers up to a cutoff, here here determined by a vairation in the second derivative over the given numbers of standard deviation.
plot bool will plot the grouping projection in 2d.
-
cluster_by_distance
(cutoff_dist=1.0, plot=True)¶ Find the grouping by allowing all mergers up to a given join distance. Plot will plot the grouping projection in 2d.
-
cluster_by_index
(index, plot=True)¶ Find the grouping by allowing all mergers up to a given index, There will be N-index clusters where N is the number of samples (-1 from there being N-1 maximum joins is cancled by +1 from indexs starting at 0). Plot will plot the grouping projection in 2d.
-
cluster_distance_plot
(option='all', ax=None, last_few=True)¶ Plot the option vs iterations on the given axis
Parameters: - option (string (optional)) –
What to plot aginst iteration, choose from: - ‘dists’ plots the join distance - ‘1st’ plots the numerical first derivative - ‘2nd’plots the numerical second derivative - ‘all’ (default) plots plots all of the above
(ignores ax and last few) - ax (Matplotlib axis (optional)) – The axis to plot on, one is created if not given. If ‘all’ chosen then this setting is ignored
- last_few (bool (optional)) – Plot only the last 25 points (or all if less than 25 in total). If ‘all’ chosen then this setting is ignored
- option (string (optional)) –
-
iterate
()¶ Merge closest pairs until all datapoints are connected. This has to be done before any clustering may occure.
Segments¶
author: Richard Bonye (github Boyne272) Last updated on Tue Aug 27 18:37:15 2019
-
class
TSA.merging.Segments.
Mask_utilities
(mask, connected=True)¶ A collection of utilities for minipulating a mask, such as getting its outline or creating an rgba array for plotting
Mask_utilities(mask, connected=True)
Parameters: - mask (2d numpy array) – integer array to be used
- connected (bool, optional) – if true will enforce connectivity of each region in the mask via skimgs morphology package. Defaults to true.
-
class
TSA.merging.Segments.
segment
(cords, edges, index, group_obj)¶ A single segment which holds its constituent pixels, edge pixels and figures out its neighbours. This is to be used by the segment_group obj.
segment(cords, edges, index, group_obj)
Parameters: - cords (2d numpy array) – The cordinates of this segments pixels in shape (N, 2) where N is the number of pixels and the second axis is the X, Y cordinates
- edges (2d numpy array) – The cordinates of this segments edge pixels in the same shape as cords
- index (int) – The id of this segment used in the segment_group.seg_dict
- group_obj (segment_group obj) – The segment_group which holds all segment objects. This is used to access the locations of other segments in order to find neighbours
-
edge_mask
(arr)¶ Fill the given 2d arr at this segments edge values with this segments edge confidence at that boarder.
-
edge_plot
(ax)¶ Plot this pixles edges on the given axis with a different color for each edge and label with a legend.
-
fill_mask
(rgba, color=None, alpha=0.4)¶ Fill the given 3d rgba array with this segents cordinates using the given color values and given alpha (opaqueness).
-
class
TSA.merging.Segments.
segment_group
(mask)¶ Object that handles a feature extraction and merging of a segment mask though the use of segment instances. Upon initalisation these segments locate their neighbours, edges and enforce connectivity of each segment. Note the neighbour identification is a costly process.
segment_group(mask)
Parameters: mask (2d numpy array) – integer array of a mask governing a segmentation -
assign_clusters
(clusters)¶ Store the clusters of each segment for use in merge_by_cluster. This is done seperately so that the segments of each cluster can be plotted before the merging is done.
-
edge_confidence
(confidence_func, func_vars)¶ Loop over every segment with the confidence function to obtain the edge confidence between every neighbour pair. This confidence value is then stored on each segment and used in the merging functions.
Parameters: - confidence_func (callable) – callabel which accepts (X_cords, Y_cords, *func_vars) where cordinates are of the segment edge with one neighbour and returns a single value of the confidence of an edges presence. By default >1 is consider to be an edge and <-1 is considered to be no edge, however this can be overwritten in the mergeing functions. Note that X,Y is given in the visible sense (i.e. an array is indexed [y, x])
- func_vars (tuple of vairables) – vairable to be passed into the fucntion to evaluate the segments edge confidence. This is often some edge detected versions of the original image to be indexed at the segments cordinates
-
enforce_size
(min_size=50)¶ Merge small sections below the given area with their largest neighbour
-
feature_extraction
(extract_func, func_vars)¶ Loop over every segment with the extract function to obtain the feature vectors for each segement.
Parameters: - extract_func (callable) – callabel which accepts (X_cords, Y_cords, *func_vars) where the cordinates are of a single segment and returns a tuple of features of that segment. Note that X,Y is given in the visible sense (i.e. an array is indexed [y, x])
- func_vars (tuple of vairables) – vairable to be passed into the fucntion to evaluate the segments feaures. This is often some filtered versions of the original image to be indexed at the segments cordinates
Returns: feats – array of segment features with shape (n segments, n features)
Return type: 2d array
-
get_cluster_mask
()¶ Returns a mask of the cluster of each segment
-
merge_by_cluster
(edge_present=1.0)¶ After a clustering has been assigned this merges segments that are adjasent and of the same group.
If an edge_confidence has been calculated for the segments than the extra condition that the edge value is below the edge_present parameter is requiered.
-
merge_by_edge
(edge_absent=-1.0)¶ After an edge_confidence hsa been calculated merge any adjasent pairs with edge value less than the edge_absent parameter.
-
plot
(option='default', ax=None, **kwargs)¶ Plot the specified option on the axis if given. All of these are designed to be plotted over the original image, either by passing axis with this image already on it or by passing the image array as kwarg ‘back_img’.
Valid options are:
- ‘both’ or ‘default’
- shows the merged segments edges and the original segment edges in a different color so what has been merged is clear.
- ‘orig_edges’
- shows the original segments edges.
- ‘merged_edges’
- shows the merged segments edges.
- ‘cluster’
- plots a mask that is transparent only where segments belong to the cluster specified by the kwarg ‘cluster’.
- ‘cluster_all’
- plots every cluster as above on a multi axis figure. Must give back_img kwarg so that it can be put on each subplot.
- ‘segment’
- plots a mask that shades in the segment id given with the kwarg ‘segment’ a slighly translucent red.
- ‘segment_edge’
- plots the edges of the segment id given with the kwarg ‘segment’. These are colored and labeled different for each different neighbouring segment (if a pixel has more than one neighbour segment adjasent it is random which is indicated)
- ‘edge_conf’
- plot every segment edge in a color that represents its edge confidence value.
-

PicoContainer's scope hinges on parent/child container relationships. From a PicoContainer instance you can make a child container via makeChildContainer() or addChildContainer(..).
These hierarchies of container can be set up with parents and children refering to each other, or children referring to parents only, or parents referring to children only. This changes the way that things work considerably. If a child has its parent registered, then it can lean on it for component resolution (but not without). If a parent has its child registered asa child, then it can manage it (start, stop, dispose cascade into children).
Web frameworks that leverage PicoContainer typically construct a tree of containers. For example an application level container maintains components that can be shared across the application. The application container will have child containers to maintain session level components. These session level containers can resolve dependencies through their parent containers, but the application container will have no visibility into its children. Additionally these child container do not have visibility into their sibling containers. With this design, containers can easily be garbage collected at the end of their scope.
Here are examples of parent/child setup:
parent = new DefaultPicoContainer(); parent.addComponent(Apple.class); parent.addComponent(Orange.class); parent.addComponent(Pear.class); child = parent.makeChildContainer(); child.addComponent(DependsOnApple.class); // this is OK parent.start(); // cascades to child just fine
parent = new DefaultPicoContainer(); parent.addComponent(Apple.class); parent.addComponent(Orange.class); parent.addComponent(Pear.class); child = parent.addChildContainer(new DefaultPicoContainer()); child.addComponent(DependsOnApple.class); // this is NOT OK. child can't see parent parent.start(); // cascades to child just fine
parent = new DefaultPicoContainer(); parent.addComponent(Apple.class).addComponent(Orange.class).addComponent(Pear.class); child = parent.addChildContainer(new DefaultPicoContainer(parent)); child.addComponent(DependsOnApple.class); // this is OK parent.start(); // cascades to child just fine
parent = new DefaultPicoContainer(); parent.addComponent(Apple.class).addComponent(Orange.class).addComponent(Pear.class); child = new DefaultPicoContainer(parent); child.addComponent(DependsOnApple.class); // this is OK parent.start(); // does NOT cascades to child
There is no limit to the extent of the chained containers, for example - great grandparent, grandparent, parent, child, is OK.
Garbage collection is the standard way of disposing of scoped containers. If the children refer to the parents, then assign child to null just works. If the parents refer to the children too, then you'll have to do a removeChildContainer(..) first before it will be eligible for garbage collection.
See web frameworks also.

Given a sequence a1, a2, ... of numbers, the finite sum a1 + a2 + ··· + an, where n is an nonnegative integer, can be written
If n = 0, the value of the summation is defined to be 0. The value of a finite series is always well defined, and its terms can be added in any order.
Given a sequence a1, a2, ... of numbers, the infinite sum a1 + a2 + ··· can be written
which is interpreted to mean
If the limit does not exist, the series diverges; otherwise, it converges. The terms of a convergent series cannot always be added in any order. We can, however, rearrange the terms of an absolutely convergent series, that is, a series for which the series also converges.
For any real number c and any finite sequences a1, a2, ..., an and b1, b2, ..., bn,
The linearity property is also obeyed by infinite convergent series.
The linearity property can be exploited to manipulate summations incorporating asymptotic notation. For example,
In this equation, the Θ-notation on the left-hand side applies to the variable k, but on the right-hand side, it applies to n. Such manipulations can also be applied to infinite convergent series.
For real x ≠ 1, the summation
is a geometric or exponential series and has the value
When the summation is infinite and |x| < 1, we have the infinite decreasing geometric series
For positive integers n, the nth harmonic number is
(We shall prove this bound in Section A.2.)
Additional formulas can be obtained by integrating or differentiating the formulas above. For example, by differentiating both sides of the infinite geometric series (A.6) and multiplying by x, we get
for |x| < 1.
For any sequence a0, a1, ..., an,
since each of the terms a1, a2, ..., an-1 is added in exactly once and subtracted out exactly once. We say that the sum telescopes. Similarly,
As an example of a telescoping sum, consider the series
Since we can rewrite each term as
we get

Search your POI vector data or map layer data¶
With GEE, you can perform simple text searches of your POI vector data or map layer data. If you have one or more text fields that you would like to query from vector or map layer data in a project, you can simply add those search fields to that vector data’s layer. You include the layer as part of the vector project that you want to include in the 2D or 3D database.
For example, you may be interested in displaying the US Census Bureau population statistics on your map or globe, based on county name. Once you have added the census data as a layer in a vector project, you can easily add the search fields to the individual population data layer in the vector project. You can also choose how you want the labels for the search results to appear on the map, such as search and display a field, or simply display it.
Add search fields to individual layers of your vector projects
After you have added a layer to a vector project, you can configure it to add search functionality. You use the Search tab in the Layer Properties dialog to specify one or more search fields to query your source data.
To add search fields to individual layers of a vector project:
In the Asset Manager, double-click the name of the project in which you want to modify layers. The Vector Project Editor displays the list of layers included in the project.
View the layer properties for a resource in a project by right-clicking the layer name in the Vector Project Editor and selecting Layer Properties from the context menu.
Click the Search tab in the Layer Properties dialog.
Click . The Add Search Field dialog appears.
Select the desired field from the Column Name drop-down list. Select an option from the Use drop-down list:
- Search Only - Google Earth EC searches against the selected field but does not display the results.
- Display Only - Google Earth EC displays the values of the selected field in the results but does not search against the selected field.
- Search and Display - Google Earth EC searches against the selected field and displays the results.
An example of search fields added to a layer in a vector project describes the use of US Census Bureau data and setting up fields to query the County name and display the population per county in the results shown in the client. See the tutorial lesson Specifying Search Fields for Individual Layers.
Repeat the steps above for each additional field you want to add to the search. Your selections appear on the list of search fields on the Search tab in the order in which you added them:
The order in which the fields appear on this list is the order in which they appear in the description balloon in the client. (The fields designated as Search Only do not affect the order in which the fields to be displayed appear.)
To change the order in which the fields appear, select a field and use the and arrows.
To remove a field, select it and click .
Click the OK button to save the Search field properties.
Select File > Save in the Vector Project Editor to save the changes to the layer.
Note
This search performs an exact match, which means that the Google Earth EC user must enter the value exactly as it appears in the database. It can also perform a wildcard search, so users can enter part of the text they want to match. For example, if a user enters “dakota” in a state search, the search results match “North Dakota” and “South Dakota”.
Once you have added your POI vector project to the database you want to publish, push it to GEE Server, then turn on POI Search when you publish.
Setting the +Enhanced Search to On will first perform a POI search against the vector data in your database, and if no results are found, perform an Enhanced Search using the GeocodingFederated search plug-in, searching your database for queried places or coordinates.
For example, if your query in Google Earth EC for a city name returned no results via the POI search plug-in, the GeoFederated search plugin would automatically search for that city name.
Note
The POI Search option in the Publish dialog is only available if you build your database with POI data as a vector resource layer. If you want to perform a POI search on a database external to your globe or map, e.g., on a different server, you can use the POI Search tab or create your own custom search plug-in.
Once you have added the search fields, the main Search tab in Google Earth EC displays the POI search and includes the field(s) that you specified for your queries.
Specify POI Search tab settings
You can also modify the appearance of the POI search tab in Google Earth EC by editing the system search tab, POI Search, which sets the query parameters for the search fields you added to your vector layer, as well as specifying the labels for the tab, query field, and suggestion box.
To specify the settings of the POI Search tab:
In the GEE Server Admin console, click Search tabs.
Check the box next to POISearch, then click Edit.
The Edit Search Definition dialog appears.
Edit the name of the system search tab to create your own POISearch tab definition. You cannot modify system search tabs without changing the name.
Edit the label, specify any query parameters and modify the field label and suggestion box as required.
Click the Save button.
Click Databases to swtich to the list of available databases on GEE Server. Check the box next to the database you want to publish with search, then click Publish. The Publish dialog appears.
Change the POI Search option to On.
Setting the +Enhanced Search to On also will first perform a POI search against the vector data in your database, and then, if no results are found, perform an Enhanced Search using the GeocodingFederated search plug-in, searching your database for queried places or coordinates.
Click the Search tabs drop-down list to add your POI search tab.
Click the Publish button. A message appears to confirm the successful publishing process.

Brook Taylor, born at Edmonton on August 18, 1685, and died in London on December 29, 1731, was educated at St. John's College, Cambridge, and was among the most enthusiastic of Newton's admirers. From the year 1712 onwards he wrote numerous papers in the Philosophical Transactions, in which, among other things, he discussed the motion of projectiles, the centre of oscillation, and the forms taken by liquids when raised by capillarity. In 1719 he resigned the secretaryship of the Royal Society and abandoned the study of mathematics. His earliest work, and that by which he is generally known, is his Methodus Incrementorum Directa et Inversa, published in London in 1715. This contains [prop. 7] a proof of the well-known theorem
f (x + h) = f (x) + hf′ (x) + h2/2! f ″(x) + ... ,
by which a function of a single variable can be expanded in powers of it. He does not consider the convergency of the series, and the proof which involves numerous assumptions is not worth reproducing. The work also includes several theorems on interpolation. Taylor was the earliest writer to deal with theorems on the change of the independent variable; he was perhaps the first to realize the possibility of a calculus of operation, and just as he denotes the nth differential coefficient of y by yn so he uses y-1 to represent the integral of y; lastly, he is usually recognized as the creator of the theory of finite differences.
The applications of the calculus to various questions given in the Methodus have hardly received that attention they deserve. The most important of them is the theory of the transverse vibrations of strings, a problem which had baffled previous investigators. In this investigation Taylor shews that the number of half-vibrations executed in a second is
where L is the length of the string, N its weight, P the weight which stretches it, and D the length of a seconds pendulum. This is correct, but in arriving at it he assumes that every point of the string will pass through its position of equilibrium at the same instant, a restriction which D'Alembert subsequently shewed to be unnecessary. Taylor also found the form which the string assumes at any instant.
The Methodus also contains the earliest determination of the differential equation of the path of a ray of light when traversing a heterogeneous medium; and, assuming that the density of the air depends only in its distance from the earth's surface, Taylor obtained by means of quadratures the approximate form of the curve. The form of the catenary and the determination of the centres of oscillation and percussion are also discussed.
A treatise on perspective by Taylor, published in 1719, contains the earliest general enunciation of the principle of vanishing points; though the idea of vanishing points for horizontal and parallel lines in a picture hung in a vertical plane had been enunciated by Guido Ubaldi in his Perspectivae Libri, Pisa, 1600, and by Stevinus in his Sciagraphia, Leyden, 1608.

In this course, you will learn how to design technologies that bring people joy, rather than frustration. To do this, you'll learn techniques for rapidly prototyping and evaluating multiple interface alternatives — and why rapid prototyping and comparative evaluation are essential to excellent interaction design. You'll learn how to conduct fieldwork with people to help generate design ideas. You'll learn how to make paper prototypes and low-fidelity mock-ups that are interactive — and how to use these designs to get feedback from teammates, clients, and users. You'll learn principles of visual design, perception and cognition so that you can effectively organize and present information with your interfaces. And you'll learn how to perform and analyze controlled experiments online.
Through a series of weekly assignments, you will complete a quarter-long project in teams of three. Each week, in small design studios, you present and discuss work with peers. The setting for the course is mobile web applications. The constraints of this small form factor set the stage for this challenge.

Now that we've written an application, let's distribute it across a network. The BookServer runs on one computer and the client program on another.


Use route
at class or instance level to get the URL of given action.
Returned URL will consist of controller's base URL and the action's path.
If controller does not respond to given action, it will simply use it as part of URL.
If called without arguments it will return controller's base URL.
Example:
class App < E map '/books' def read # ... end def test route :read #=> /books/read end end App.route #=> / App.route :read #=> /books/read App.route :blah #=> /books/blah
Worth to note that route
are RESTful friendly,
meant you can pass action name without REST verb:
class App < E map '/' def post_edit route(:post_edit) #=> /edit route(:edit) #=> /edit end def put_edit route(:put_edit) #=> /edit route(:edit) #=> /edit end end App.route(:post_edit) #=> /edit App.route(:edit) #=> /edit App.route(:put_edit) #=> /edit App.route(:edit) #=> /edit
If any params given(beside action name) they will become a part of generated URL.
Example:
class News < E def index route :latest___items, 100 #=> /news/latest-items/100 end def latest___items ipp = 10, order = 'asc' # ... end end News.route #=> /news News.route :latest___items #=> /news/latest-items News.route :latest___items, 20, :desc #=> /news/latest-items/20/desc
If a Hash given, it will be passed as query string.
Example:
route :read, :var => 'val' #=> /read?var=val # nested params route :view, :var => ['1', '2', '3'] #=> /view?var[]=1&var[]=2&var[]=3 route :open, :vars => {:var1 => '1', :var2 => '2'} #=> /open?vars[var1]=1&vars[var2]=2
To get action route along with format, pass the action name as string, having desired format as suffix.
If action does not support given format, it will simply be used as a part of URL.
Example:
class Rss < E map :reader format :html, :xml def mini___news # ... end end Rss.route :mini___news #=> /reader/mini-news Rss.route 'mini___news.html' #=> /reader/mini-news.html Rss.route 'mini___news.xml' #=> /reader/mini-news.xml Rss.route 'mini___news.json' #=> /reader/mini___news.json
You can also append format to last param and all the setups set at class level will be respected, just as if format passed along with action name.
Please note that though last param given with format, inside action it will be passed without format, so you do not need to remove format manually.
Example:
class App < E map '/' format :html def read item = nil # on /read item == nil # on /read/news item == "news" # on /read/book.html item == "book", not "book.html" # on /read/100.html item == "100", not "100.html" # on /read/blah.xml item == "blah.xml", cause ".xml" format not served end end App.route :read, 'book.html' #=> /read/book.html App.route :read, '100.html' #=> /read/100.html App.route :read, 'etc.html' #=> /read/etc.html App.route :read, 'blah.xml' #=> /read/blah.xml
If you need just the action route, without any params, use []
at class or instance level.
Will return nil
if given action not found or does not support the given format.
Example:
class Index < E map :cms format :html def read end def quick___reader end def test self[:read] #=> /cms/read self[:quick___reader] #=> /cms/quick-reader self['quick___reader.html'] #=> /cms/quick-reader.html self['quick___reader.json'] #=> nil self[:blah] #=> nil end end Index[:read] #=> /cms/read Index[:quick___reader] #=> /cms/quick-reader Index['quick___reader.html'] #=> /cms/quick-reader.html Index['quick___reader.json'] #=> nil Index[:blah] #=> nil

params
- a mix of GET and POST params. Can be accessed by both symbol and string keys.
Example:
class App < E map '/' def test # on /test?foo=bar params[:foo] == "bar" # ... end end
[ contents ↑ ]
To pass control to another action or controller, use pass
.
Important: If no params given, actual params will be passed.
Example: - Pass control to :archived action if page id is less than 100_000
class App < E def index id id = id.to_i pass :archived if id < 100_000 # # code here will be executed only when id > 100_000 # end end
Example: - Pass control to :json action if browser accepts JSON. If some params given, they will be passed as arguments to destination action.
class App < E def index pass(:json, params[:type], params[:id]) if accept?(/json/) # ... end end
Example: - Passing control with modified arguments and custom HTTP params.
def index pass :some_action, :some_arg, :foo => :bar end
If first argument is a valid Espresso controller, the control will be passed to it.
Example: - Passing control to inner app
class News < E def index id, page = 1 # ... end end class Index < E map '/' def index pass News, :index if params[:type] == 'news' # ... end end
By default, a GET request will be issued.
To use another request method, append it to the used method.
Example:
pass_via_post :some_action
[ contents ↑ ]
Sometimes you need to invoke some action(on same or inner controller) and get the returned body.
This is easily done by using fetch
.
fetch
will invoke some action(via HTTP) inside current or given controller and returning the body.
Basically, this is same as pass
except it returns the body instead of halting request processing.
Another important difference is that fetch
will not pass actual HTTP params.
Example:
class Store < E def products @latest_blog_posts = fetch(Blog, :latest) # ... end def featured_products # ... end end class Blog < E def index @featured_products = fetch(Store, :featured_products) # ... end end
If you need status code and/or headers, use invoke
instead, which will return a Rack response Array.
It is also possible to use a request method other than default GET.
Example:
fetch_via_post :some_action invoke_via_put :some_action # etc.
Also an XHR request can be mimed:
xhr_fetch :some_action xhr_invoke :some_action # etc.
And of course XHR requests can be issued via any request method:
xhr_fetch_via_post :some_action xhr_invoke_via_delete :some_action # etc.
[ contents ↑ ]
halt
will interrupt any process and send an arbitrary response to browser.
It accepts from 0 to 3 arguments.
If argument is a hash, it is added to headers.
If argument is a Integer, it is treated as Status-Code.
Any other arguments are treated as body.
If a single argument given and it is an Array, it is treated as a bare Rack response and instantly sent to browser.
Example:
def index halt 'Hit the Road Jack' if SomeHelper.malicious_params?(env) # ... end
Example: - Status code
def index begin # some logic rescue => e halt 500, exception_to_human_error(e) end end
Example: - Custom headers
def news if params['return-rss'] halt rssify(@items), 'Content-Type' => mime_type('.rss') end end
Example: - Rack response
def download halt [200, {'Content-Disposition' => "attachment; filename=some-file"}, some_IO_instance] end
[ contents ↑ ]
redirect
will interrupt any process and redirect browser to new address with status code 302.
To redirect with status code 301 use permanent_redirect
.
To wait until request processed, use delayed_redirect
or deferred_redirect
.
If an existing action passed as first argument, it will use the route of given action for location.
If first argument is a valid Espresso controller, it will used setup to build the path.
Example: - Basic redirect with hardcoded location(bad practice in most cases)
redirect '/some/path'
Example: - Basic redirect with dynamic location
class Articles < E def index redirect route # => /articles redirect :read, 100 # => /articles/read/100 redirect News # => /news redirect News, :read, 100 # => /news/read/100 end def read id end end
[ contents ↑ ]
reload
will simply refresh the page.
Example: - Refreshing with same GET params
def index # ... reload end
Example: - Refreshing with custom GET params
def index # ... reload :some => 'param', :some_another => 'param' end
[ contents ↑ ]
Espresso allow to set error handlers that can be used to throw errors with desired status code and body.
When setting error handler, you should provide status code and a proc that will generate the body.
The proc may accept an argument. That will be the error message.
When using handler, the only required argument is status code.
If error message given as 2nd argument, it will be passed to the error handler proc as first argument.
Example: - Setting and using 404 error handler
class News < E error 404 do |message| "Some Error Occurred: #{ message }" end def index id @page = PageModel.first(:id => id) @page || error(404, "Page Not Found, sad...") # will return 404 status code with body # "Some Error Occurred: Page Not Found, sad..." # ... end end
Example: - Setting and using 500 error handler
class News < E error 500 do |exception| "Fatal Error Occurred: #{ exception }" end # now if yous actions(or hooks) raise an exception, # it will be rescued and passed to your error handler. def index id some risky code here end # will return 500 status code with body # "Fatal Error Occurred: undefined local variable or method `here'" end
Example: Using handler without passing an error message
class App < E error 404 do "Ouch... something weird happened or you just visited a wrong URL..." end def page id error(404) unless @page = PageModel.first(:id => id) # ... end end

before
and after
allow to set callbacks to be called before and after action processed.
Example:
class App < E before do @started_at = Time.now.to_f end after do puts " - #{ action } consumed #{ Time.now.to_f - @started_at } milliseconds" end # ... end
To set callbacks only for specific actions, use actions names as arguments(matchers).
Example: - Extract item from db only before :edit, :update and :delete actions
class App < E before :edit, :update, :delete do @item = Model.first(:id => action_params[:id].to_i) end def edit id # ... end def update id # ... end def delete id # ... end end
Also regular expressions can be used as arguments(matchers).
Example: - any action containing "js" in its name will respond with "application/javascript" Content-Type
before /_js_/ do content_type '.js' end
Please Note that before
is just an alias for setup
.

Types supported:
Example: - All actions under Admin controller will require Basic authorization
class Admin < E auth do |user, pass| [user, pass] == ['admin', 'somePasswd'] end end
Example: - Only :my_bikini_photos action will require(Basic) authorization
class MyBlog < E setup :my_bikini_photos do auth :my_bikini_photos do |user, pass| user == "admin" && pass == "super-secret-password" end end def my_bikini_photos # HTML containing top secret photos end end
Example: - Everything under Admin slice will require(Digest) authorization
module Admin class Products < E # ... end class Orders < E # ... end end app = Admin.mount do digest_auth do |user| users = { 'admin' => 'password' } users[user] end end app.run

In order sessions to work they have to be enabled first.
Sessions are enabled at app level and by default can be stored in memory, cookies or memcache.
You can of course use any Rack session adapter, for example rack-session-mongo
.
Example: - Keeping sessions in memory
class App < E # ... end app = App.mount app.session :memory app.run
Example: - Keeping sessions in cookies
class App < E # ... end app = App.mount app.session :cookies app.run
Example: - Keeping sessions in memcache
class App < E # ... end app = App.mount app.session :memcache # or app.use Rack::Session::Memcache, :with, :some => :args app.run
Example: - Keeping sessions in mongodb
$ gem install rack-session-mongo
class App < E # ... end require 'rack/session/mongo' app = App.mount app.session Rack::Session::Mongo, :with, :maybe, :some => :args app.run
Read/Write Sessions
session['session-name'] = 'value' session['session-name'] #=> value
Deleting
session.delete 'session-name'
Burn after reading! :)
flash
allow to store a message that will be purged after first read.
The message are stored in sessions and are consistent between requests.
Example:
# setting message flash[:message] = 'top secret info' # read message flash[:message] #=> top secret info # message automatically purged after reading flash[:message] #=> nil
[ contents ↑ ]
Example: - Setting a cookie
cookies['cookie-name'] = 'value'
Example: - Reading a cookie
cookies['cookie-name'] #=> value
Example: - Setting a cookie with custom options
cookies['question_of_the_day'] = {:value => 'who is not who?', :expires => Date.today + 1, :secure => true}
Example: - Deleting a cookie
cookies.delete 'cookie-name'

Example: - Setting RSS content type at class level, for all actions
class Rss < E content_type '.rss' # ... end
Example: - Setting RSS content type only for :feed and :read actions
class Rss < E setup :feed, :read do content_type '.rss' end end
Example: Setting content type inside action
class App < E def users content_type('.json') if accept?(/json/) # ... end end

Updating Content-Type
header by adding specified charset.
Can be set exactly as Content-Type, at class and/or instance level.
Important: - charset
will update only the header,
so make sure that returned body is of same charset as header, if that needed at all.
class App < E charset 'UTF-8' setup /_jp\Z/ do # setting JIS charset for actions ending in _jp charset 'Shift_JIS-2004' end # ... end

Control content freshness by setting Cache-Control header.
It accepts any number of params in form of directives and/or values.
Can be set at class and/or instance level.
Directives:
Values:
Example: Setting Cache-Control header at class level
class App < E cache_control :private, :max_age => 60 # ... end
Example: Setting Cache-Control header at instance level
def some_action cache_control :public, :must_revalidate, :max_age => 60 # Cache-Control header will be set to # Cache-Control: public, must-revalidate, max-age=60 # ... end def another_action cache_control :public, :must_revalidate, :proxy_revalidate, :max_age => 500 # Cache-Control header will be set to # Cache-Control: public, must-revalidate, proxy-revalidate, max-age=500 # ... end
[ contents ↑ ]
Set Expires
header and update Cache-Control
by adding directives and setting max-age value.
First argument is the value to be added to max-age value.
It can be an integer number of seconds in the future or a Time object indicating when the response should be considered "stale".
Other params are passed to cache_control!
instance method.
Can be set at class and/or instance level.
Example:
def some_action expires 500, :public, :must_revalidate # Cache-Control: public, must-revalidate, max-age=500 # Expires: Tue, 17 Jul 2012 11:26:58 GMT end

Set the "Last-Modified" header indicating last modified time of the resource.
Then, if the current request includes an "If-Modified-Since" header that is bigger or equal, the processing will be halted with an "304 Not Modified" response.
Also, if the current request includes an "If-Unmodified-Since" header that is less than "Last-Modified", the processing will be halted with an "412 Precondition Failed" response.
Example:
def some_action last_modified Time.now - 600 end

Usually the browser informs the app about accepted content type via HTTP_ACCEPT
header.
accept?
is a helper allowing to disclose what content type are actually accepted/expected by the browser.
It accepts a string or a regular expression as first argument and will compare it to HTTP_ACCEPT
header.
If you make a request via XHR, aka Ajax, and request JSON content type,
accept?
will return a string containing "application/json".
Having this, it is easy to determine what content type to send back.
Example:
class App < E def some_action if accept? /json/ content_type '.json' end end end
Other browser expectations:
Example:
accept_charset? 'UTF-8' accept_charset? /iso/ accept_encoding? 'gzip' accept_encoding? /zip/ accept_language? 'en-gb' accept_language? /en\-(gb|us)/ accept_ranges? 'bytes'

Allow to cache the result of an arbitrary block and use the result on consequent requests.
Note: Value is not stored if block returns false or nil.
Cache can be cleared by calling clear_cache!
method.
If called without params, all cache will be cleared.
To clear only specific blocks, pass their IDs as params.
Example:
class App < E def index @db_items = cache :db_items do # fetching items end @banners = cache :banners do # render banners partial end # ... end def products cache do # fetch and render products end end after do if 'some condition occurred' # clearing cache only for @banners and @db_items clear_cache! :banners, :db_items end if 'some another condition occurred' # clearing all cache clear_cache! end end end
By default, the cache will be kept in memory.
If you want to use a different pool, set it by using cache_pool
at app level.
Just make sure your pool behaves like a Hash,
Meant it should respond to []=
, []
, delete
and clear
.

send_file
will send file content to browser, inline.
The only required argument is the full path to file.
Example:
def theme____css send_file File.expand_path('../../public/theme.css', __FILE__) end
All files properties are detected automatically, however you can modify them by passing an hash of below options:
Example:
send_file '/path/to/file', :cache_control => 'max-age=3600, public, must-revalidate'
Recommended to use only with small files.
Or setup your web server to make use of X-Sendfile and use Rack::Sendfile
.

send_files
allow to serve all files from a given directory.
Example:
send_files '/path/to/dir'
[ contents ↑ ]
attachment
works as send_file
except it will instruct browser to display "Save" dialog.
Example:
attachment '/path/to/file'
[ contents ↑ ]
response.headers
, or just response[]
, allow to read/set headers to be sent to browser.
Example:
response['Max-Forwards'] #=> nil response['Max-Forwards'] = 5 response['Max-Forwards'] #=> 5 # browser will receive Max-Forwards=5 header
