Add very simple and basic condition to run this job. Write a condition in groovy script format. You can use environment variable. If the expression cannot be evaluate, false is assumed.
Example : ${BUILDNUMBER} % 2 == 1 for running this job every two times or if you have a string parameter you cas use "${Name}" == "Myjob".

PingPong!
Rules:
Ping pong will count up to your inpurted number except for the following conditions
- If number is divisible by 3 the output will be "ping"
- If number is divisible by 5, the output will be "pong"
- If number is divisible by 15, the output will be "pingpong"

Types of apprenticeships that you can apply for in the rail services sector.
This apprenticeship covers the many occupations that help to deliver rail services to the millions of passengers that use trains every year.
Rail services involves many tasks, like driving the trains, operating signals and crossing barriers, communicating between stations and trains, assisting passengers both on board trains and at stations, and moving trains into position at stations.
You’ll choose your area of specialisation:
You’ll learn technical skills and how to:
There are 2 types of rail services apprenticeships.

IMHO, this copy should be performed generally, i.e. also in the case described by the subsequent paragraph: If the IP address is not managed by the DHCP server, then a DHCPLEASEUNKNOWN message must be returned. that therefore might be amended to say: If the IP address is not managed by the DHCP server, then a | DHCPLEASEUNKNOWN message MUST be returned, with that IP address | set in the "ciaddr" field. [The original 'must' should be a 'MUST' because the alternatives are also specified as a 'MUST' -- or else the specification would be incomplete.] Taken together, it might be preferable to restate this fact by only changing the first paragraph cited above as follows, and leave the second paragraph unchanged with the exception of the 'must': In the event that an IP address appears in the "ciaddr" field of a | DHCPLEASEQUERY message, then that IP address MUST be set in the | "ciaddr" field of any reply returned. | If that IP address is one managed by the DHCP server, then it MUST | reply with a DHCPRELEASEACTIVE or DHCPLEASEUNASSIGNED message. If the IP address is not managed by the DHCP server, then a | DHCPLEASEUNKNOWN message MUST be returned. Please comment on which alternative you prefer.

EL CID A film review by Ralph Benner Copyright 1996 Ralph Benner
The era of the roadshow -- big budgeted movies designed to battle the rapid intrusion of television on box office receipts in the Fifties and Sixties -- was mostly a pompous affair: movies that were one or two hours longer than needed, elevated prices for reserved seats and refreshments (like BEN-HUR candy bars), mementos such as stagebills & souvenir booklets & sometimes glossy still packets, preludes, overtures, intermissions, exit music. Most of these nothing-money-can't-buy spectaculars, in spite of honorable intentions, weren't worth the trouble; they were mostly globs of lush sets, costumes, over-scored music, special effects demonstrations, ear-splitting sound, eye-popping panoramas -- reasons to spend money, to advance movie technology, to keep a lot of people working. What other reasons were there for Sam Bronston to make THE FALL OF THE ROMAN EMPIRE? (But in Bronston's defense: his pre-Epcot Rome has never been equaled, though the pornographic CALIGULA has a few settings that come close, and Richard Fleischer's BARABBAS is so plausibly evocative of the period that its "realism" is out and out depressing.) Of all the epics that received the deluxe treatment, Joseph L. Mankiewicz's CLEOPATRA and George Steven's THE GREATEST STORY EVER TOLD were so badly butchered by executive fiat -- editing the movies down because of complaints by the few and for the additional purpose of trying to squeeze in more showings per day for more bucks -- that they have become objects of sympathy. (Fox's video of CLEOPATRA, even without letterboxing, might be the first quietly "restored" spectacle, yet Fox's two video releases of GREATEST STORY remain 65 minutes short of its original running time.) After the successful restoration of LAWRENCE OF ARABIA, spearheaded by Steven Spielberg and Martin Scorsese, and following the renovation of SPARTACUS, Scorsese set his sights on Anthony Mann's EL CID, considered by many lovers of the genre as its epitome. Most of Scorsese's push to restore these (and soon-to-be other) films has to do with the fear of losing the productions, as intended by their makers, to the destructive elements of time, environment and neglect on original negatives. As he said of EL CID, "They can't make them like this anymore." He guesstimated that the 1960-61 $14,000,000 cost of EL CID would approximate $129,000,000 in 1993 dollars. Probably an exaggerated figure, but producers reportedly spent something close to $80-to-100 million on the megabomb THE LAST ACTION HERO and something like $170 million on WATERWORLD, and some movie makers are trying get $100 million to make an epic on the Crusades (with Arnold!), so Scorsese's regrets should not be confused with future possibilities. What he's saying is movie makers most likely won't attempt to re-make a LAWRENCE or an EL CID again, and that's the strongest imperative behind the restorations.
When released in 1961, EL CID received some good reviews -- ending up on Time's and the N.Y. Times' "Ten Best" lists -- but it came nowhere near the domestic box office of BEN-HUR. It also met with unjust comparisons: looking at BEN-HUR today, there's such fraudulence -- crammed with faked backdrops, matte shots, obvious dummies on the miniature ships and in the galley, embarrassingly revealing bits of stand-ins for the principals -- that it becomes a hoot. (The 1926 BEN-HUR often more realistic, like that tempting bare-assed slave chained in the galley.) You wonder: What drove the masses to see it? Of course, the chariot race.  (Every parochial school bused students downtown to Saturday morning showings, hoping they'd be mesmerized, overwhelmed, therefore resurrected by the solemn hymns; the hope being Hollywood could do in a few hours what the Church took years to do -- transforms the kids from sinners to angelic submissives.) Having but one splendid action sequence to grab and exhaust us -- the two-man battle for the city of Calahorra directed by second unit wizard Yakima Canutt (its other action scenes more than adequate, notwithstanding Heston's comments in his self-congratulatory 1978 THE ACTOR'S LIFE) -- EL CID had handicaps and prejudices to overcome. Coming on the heals of biblical stories like THE ROBE, QUO VADIS, BEN-HUR, SOLOMON AND SHEBA, THE BIG FISHERMAN and KING OF KINGS, another Bronston spectacle, EL CID suffered not only because it's an "old Hollywood style" epic, loaded down with pageantry, encased in stilted aphorisms much like KNIGHTS OF THE ROUND TABLE and IVANHOE, but also because it's an account of Spain's greatest hero about whom American audiences were neither aware of nor really cared about. EL CID is indeed propelled along by an extensive use of epigrams, and Loren delivers more of them than any other cast member. Her best: "Since my love is not like other men, my life will not be like other lives." (When Herbert Lom, the treacherous Emir Ben Yussuf, is berating his men as softies and the camera moves in on the indispensably nellie Frank Thring, he lashes out, "You have become women!") And "old fashion" in style it is: perfunctory scenes are used to advance the story along, there's pomp and clash & bang galore, the mandatory insertion of good over evil. But unlike other medieval epics, EL CID has been lavishly wrapped in authenticity: its sets are huge but subdued in scale and detail for the 11th Century. The restoration of color and clarity have given us the chance to ooh and aah at not only the tapestries, murals, flags and other regalia but the real leathers used in costumes for Heston and Raf Vallone: they're so vividly rich that you can practically reach out and touch the textures. (Only one costume set sticks out as atrocious: King Ferdinand's crown and cape of arms look like badly sown together car decays. Forgiven when, having died, he's laid out on a black and gold tapestry, which should be sold by JCPenny. And not the only decoration from a Bronston epic that should be duplicated: Armstrong or Mannington should consider selling replications of the best floor in all of movies -- the inlaid masterpiece for Herod's palace in KING OF KINGS.) The use of Spain's real castles and landscapes add immeasurable legitimate weight -- underlining some of the overtly false, flimsy settings of BEN-HUR. For those who have only seen the pre-restored EL CID on TV, or on one of the two very poor quality video versions available, there must be disappointment because not only is the color washed out, and no overtures or exit music, but of course they miss entirely the sweep, the grandeur -- and a lot of tidbits: like watching the troops build their multi-story ramps, or catching the facial reactions of the various ladies-in-waiting, or getting to giggle at Thring's earrings or at Ben Yussuf's armies capped in turbans that in succession look like mushrooms, candied jujubes, peanut shells and the Elephant Man's head, or getting a good look at Vallone's blooded-up chest, with its skin peeled back. State of the Art might not have been a term yet coined, but Vallone's wounds, and Heston's facial scar and the arrow that's embedded into his chest are excellent 1961 makeup effects.
No American actor was born to play historic figures more than Charlton Heston. His only rivals are Englishmen -- Rex Harrison, Peter O'Toole, and Laurence Olivier, who, never looking more magisterial, steals SPARTACUS away from Kirk Douglas. The epic as genre would have continued on its loony, chaotic way without Heston, but as its center, he gave it legitimacy; somehow his mid-Western intonational Voice of All Ages and his handsome physical stature imposingly fused. He had the odd, unearned gift of penetrating our modern cynicism and could redeem the stilted formal lingo of spectaculars. And little quarrel that his shadow eclipsed those in Hollywood epics who came before him, like Gregory Peck, or the unnerving Robert Taylor, who always seemed to be waiting to break for a cigarette. Part of this has to do with Heston's ability to look appropriately weathered and flawed, as in EL CID. Yet he's not oversized, either, like the stockyard beefiness of misfit Victor Mature; there's something reassuring about how Heston's masculinity remains strongly intact despite the furs, flowing capes and silks he's often been required to wear. Because we'll never know what the men of history he's played will sould like, Heston's legacy could be that we would expect them to come close to matching him. (Especially true when he's done up as Andrew Jackson.) That doesn't mean Heston's performances have always been successful: I didn't believe but a minute or two of his Moses, no matter what vulgarian DeMille declared about the hunt for elusive facts. But Heston's inadvertently funny; how could he not be opposite Anne Baxter's camp-tramp Nefertiri? While not playing a known figure as Judah, his Oscar-winning performance was based on novelist Lew Wallace's suggestion of what Jewish royalty might have been like during the time of Roman rule over Judea. In retrospect, BEN-HUR is a spectacle of stereotype and hate: all the Romans look and act like primped-up pansies. Not unintentional: Gore Vidal, who did some of the re-writing of the script, changed the psychology of the friendship between Ben-Hur and Stephen Boyd's evil Messala to a revenge on unrequited lust -- without Heston's acknowledge. The question of the House of Hur's Jewish faith also gets cloudy: will Judah, his mother and sister convert as Christers after the climatic cure of leprosy? (They do in the novel.) The best thing about 55 DAYS AT PEKING, in which Heston's under-ultilized as an American marine battling the Boxer Rebellion, is that Peking-Imperial City set. The Roman Forum was being built for ROMAN EMPIRE when Heston signed on to do PEKING, so Bronston had his standing army of carpenters re-construct the forum into the Chinese city. God only knows what kind of pressure Heston exerted on Sir Carol Reed to avoid playing Michelangelo as a homosexual in THE AGONY AND THE ECSTASY, and though there were many other things wrong with the epic -- like the mini-documentary which opens it and avoids giving us a full frontal of David -- Heston's reticence to record the great master as he was is its major failing. Was the closely cropped beard the only hint at inclination Heston would permit? Did he not see that the Sistine Chapel is wrought with religio-homoeroticism? He insinuates with one daring pre-Freud, pre-genetic line, "God crippled me." As John the Baptist in THE GREATEST STORY EVER TOLD, Heston not only once again looked the part, he bellowed it out with great gusto. KHARTOUM, about the British general Charles Gordon, played by Heston, who must defend the city against the fanatic Arab Mahdi, performed in a left-over-tan-from-OTHELLO by Laurence Olivier, was epic short on length and viewers. Audiences were by 1966 suspicious of, if not burnt out on roadshows. And this one's got a musical score that would otherwise be litigious: composer Frank Cordel steals from SPARTACUS, LAWRENCE OF ARABIA, CLEOPATRA, even from THE AMERICANIZATION OF EMILY. Heston's not at all bad in his accent, and he's terrifically appealing in receding grayish hair and those formal duds -- particularly his gold-on-black dress uniform.  (Beginning to see a phony "family values" pattern?) Judging from the reviews of his stage appearances as Sir Thomas More in A MAN FOR ALL SEASONS, he was persuasive as the myopic numskull stuck on God's mandates. But then Heston made the fatal mistake of directing himself in a TNT-production.  The house of cards playwright Robert Bolt built collapses; there's no distinction between the reasonable assumption of moral laws and Heston's politics. As if comeuppance, he becomes a man of no season.
EL CID is the movie most of Heston's fans and many lovers of epics have enthusiastically embraced. For good reason: he's at his most chivalrous. In this present age of misogyny, watching his Cid refuse to be vanquished by or turn ugly over his love's avenging duty is reassuring; it's meant to be noble, and honorable, and it's both, but it's also something of a resurrection of sexual chemistry: the Cid's and Chimene's loin lust will not be tamed. Under Mann's direction and the marvellous lighting by cinematographer Robert Krasker, much of this hormonal alchemy is transmuted through framed posing; and it is in the barn, minutes before intermission, that they are finally relieved of their prolonged pentupness. It's the the healthiest sequence in the entire movie, with Loren at her most relaxed. Smart observers, and readers of Heston's book, will also note that there's a discernible tension between the two stars during most of the first half. If Heston's account is to be trusted, it came about because "All in all, the most trying time with an actress I can ever recall. Mind you, (Loren) is not a bitch...just more star than pro." In turn, Loren says not a word about Heston in her own book, and she's not the only actress to pointedly ignore him: Ava Gardner chose the silent routine in her bio. But watching Loren opposite Mr. Clean makes you believe her intuition early on picked up the need to create some friction because without it, their characters wouldn't spark. Mr. Clean wouldn't admit it, but Loren's gambit helps him enormously; this is his only performance in any of his epics in which the audience senses that he isn't more in love with his enemies or horses than with his leading ladies.
The Cid's other highly attractive virtue is his selfless righteousness. For example, it's fact that when he recaptured Valenica from the Emirs, he did not accept the crown of the city, as was demanded by his followers, but instead, in order to unite Spain against the invaders, took it in the name of King Alfonso, who had previously banished him into exile because he publicly humiliated the King into swearing that he had no part in the (real) assassination of his brother Sancho. Yet here's where the movie and what's known about the royal family gets factually shaky: when Ferdinand died, he willed that his empire be divided into three parts for his sons, Sancho, Alfonso and Garcia. In the movie, he wills to Sancho, Alfonso and daughter Dona Urraca, and never once is Garcia's name uttered. History records no will to a daughter. The script changed Garcia (who was in fact killed in a power grab by Alfonso) to Urraca for dramatic tension, and it is at her feet that Sancho's death lay. The writers, Philip Yordan and Fredric M. Frank, a pseudonym for blacklisted Ben Barzman, who also worked on THE TEN COMMANDMENTS and THE FALL OF THE ROMAN EMPIRE, spiced her up by suggesting that she had the incestuous hots for Alfonso, and may have had a thing for the Cid as well. (Historians interested in the private lives of these figures report the Cid was the most handsome man of his time, and that by the age of 20 he was already knighted, and that Chimene was a cousin to the royal family.) As Urraca, French actress Genevieve Page, looking like an embittered Elke Sommer, does what she can to insinuate the sinister (her clipped English helps), but, though this movie has been "fully restored," there's either reluctance on Mann and the writers's parts to dive deeper into her or that scenes were cut. This happens to Frank Thring too: though his brief moments are comic relief -- he's like the Australian version of Jay Robinson -- surely there should be more to him than what we get. (Still short of tongue, looking grotesquely rotund with his bald head and chin down to there, Thring played The Collector in MAD MAX BEYOND THUNDERDOME.) The legend of the Cid as incorruptible probably isn't quite true, either: he was a soldier of fortune-opportunist who fought on the sides of both Christians and Moslems, and was richly rewarded. Only when the North African Emirs threatened to overtake Spain did he see his heroic duty of uniting Spain. Though the movie emblemizes the oft-repeated legend of Rodrigo -- that he fell as a result of a battle-inflicted wound and rode off into history strapped, dead but open-eyed, on a white horse -- historians record that he actually died four years after defeating the Emirs in Valenica. His death at 49 is said by biographers to have been brought on by grief and shame over the huge numbers of casualties it took to do so. The Cid is buried at the cathedral in Burgos.
If Elizabeth Taylor is contemporary, out of her vocal element as the Queen of the Nile or Shakespeare's Katharina, Sophia Loren seems much at home in antiquity; her stressed, emphatic English befits the colloquial language of epics. Like Heston, it's her size and voice -- they emit a transitory authority. It's only when we think about some of what she says do we have misgivings: "Moors? You let Moors live?" (Every once in a while she sounds like Gina Lollobrigida in Vidor's SOLOMON AND SHEBA.) She looks gorgeous in costume: perhaps her best is the emerald green cote-hardie over a white bliaut with embroidered amoeba-like leaves, topped with a starched lifted collar, that she wears at the wedding banquet. (The richest-looking wardrobe, however, belongs to Douglas Wilmer as brown liquid-eyed Lord Moutamin.) And only on the big screen can we appreciate her swaying hips as she, dressed in mournful black, struts through the King's Court. Heston, once more, bitched that Loren refused to allow herself to age, noting that the movie's time span covers more than twenty years. Covering the criticize, Raf Vallone says to her, "Even all these months in the dungeon have not marred your beauty." But she was smart to resist the makeup effects: she's not there for anything other than her desirable ornamentation. Borrowing from Helen of Troy, Loren's is a face that launches a thousand men against the King-captor.
"Script, acting, images and music all act in perfect harmony," writes British author Derek Elley in THE EPIC FILM. Not exactly; the script's cliches aren't fully saved by the cast's efforts because too often the cliches are central to the movie's problems of conventionality. There's one glaringly hokey sequence that somehow Heston, who fought with Mann regularly, didn't consider worthy of fighting against: when the Cid, in exile, comes across a leper named Lazarus. A genuflection to BEN-HUR, it's appalling, and made even more so when up pops Chimene, who decides she must support her stripped-of-wealth, sexually deprived husband. You have to ask: how did she get to the locale as quickly as the Cid without him knowing it? And sometimes the acting isn't as large-scale as it is anxious, over-wrought. But the right god and goddess are in awfully fine harmony with the imagery, music and sound effects. Miklos Rozsa's orgasmic score, notes Elley, was originally written to cover almost 100% of the film, but Mann discovered in Verna Fields (who would do the film editing for BONNIE AND CLYDE and JAWS) a gifted sound technician: her matchless ear for a slap with a glove, for dueling swords, galloping horses, convinced Mann to eliminate over an hour of music. What survives is more than enough. Rozsa, who won an Oscar for BEN-HUR and died in 1995, went to Madrid to research with Nobel Prize-winning historian Dr. Ramon Menendez Pidal, who introduced the composer to the 12th Century cantigas of Santa Maria and the 13th Century cantigas of Alfonso X, which were inspired by Phrygian culture. The score's most likely at its loving zenith, and its simplest, when the Cid returns to the convent to meet, for the first time, his twin daughters, and when Chimene puts her hand to his scar. Excluding script convention, the movie's most troublesome element is in the actual sound recordings: in Heston's diary, he reported that as much as seventy percent of the soundtrack would have to be redone, "something to do with inconsistent Spanish current." What's amazing is that, in spite of the echo of hollowness -- the lack of integrity that results from looping -- the results aren't harmful, as they definitely are in BARABBAS, probably because of the decision to noisy up the soundtrack with stereophonic blasts of Rozsa's frenzied score and the sound effects. Film editor Robert Lawrence has one remarkable feat: during the joust for Calahorra, he not only has to avoid showing the double used when a sword is swinging away at the Cid's saddle, he also has to splice in Loren's reaction shots, which were filmed weeks before. (You can tell: the lighting & wind effects in the King's grand stand don't quite match the actual outdoor shots.) But the binding used to wrap it all up is Robert Krasker's painstaking photography, much of which could pass for paintings. The restoration returns glorious moments like the first scene of the Cid and Chimene together in the rotunda -- wherein the stars perform the greatest non-kiss in movie history; the Cid, underneath the spiral staircase, bracing himself against the very sword he used to kill Chimene's father; Chimene sitting in her bed chamber on her wedding night; Ferdinand's lying-in-state; the opening shot in the barn; the night scenes of Ben Yussuf's's men riding their horses towards Valenica (the movie makers used Peniscola) and his infantry banging its drums. There's not a single shot in BEN-HUR that equals them. In retrospect, given that BEN-HUR remains the most Oscar-awarded epic so far, the sentiment may come to be that EL CID is the most egregiously neglected epic by the Academy. But thanks, Marty, for returning to us foofs the gold we've long waited for.

Plugin Information |
|---|
View Slave SetupPlugin on the plugin site for more information. |
This plugin prepares slaves for build execution by letting you copy files and execute scripts before the slave gets used.
It also allows you to start and stop slaves on demand from the master node.
Label-based setup
The slave setup plugin gets executed for a slave, if the given label expression matches and on:
- Jenkins startup as a slave gets connected.
- Save of the Jenkins configuration page if the "deploy on save now" checkox is checked.
- New or re-connection of a slave.
When you install this plugin, it adds a new system configuration section that lets you specify a list of slave setup items. Each of them have to following properties:
Property |
Description |
Example |
|---|---|---|
pre-launch script |
Name of a pre-launch script relative to the jenkins home directory. This can be used to start the slave machine, before Jenkins tries to ssh it. |
./prelaunch.sh |
prepare script |
Name of a prepare script relative to the jenkins home directory (not the setup files directory, this has changed in v1.6). This can be used to aggregate files into the setup files directory, patch them, pack them, and so on... |
./prepare_files.sh |
setup files directory |
Absolute path to the directory that will be copied to the slave. The contents of this directory are copied to the home directory of the slave. |
/var/jenkins/devSlaveFiles |
setup script after copy |
Name of the script that should be executed on the slave after all files are copied. The script should be part of the files to copy. |
./slave_setup.sh |
deploy on save now |
If checked, this slave setup item will be executed on save of the jenkins configuration page. |
checked |
Label Expression |
Like jobs a slave setup item can be configured to be executed only on the slaves that match the Label Expression. |
"slaves", "!selenium", "slave1 OR slave2" |
First the directory gets copied, then the script gets run. The execution of the script is reported to the slave log. When it fails, the slave is not marked as online, so ill-prepared slaves never enter the slave pool.
This provides the administrator of the system an opportunity to prepare slaves to the state suitable for build execution. This works particularly well in conjunction with tools like Puppet that has higher-level support for this kind of task.
On-demand slave setup
This plugin also provides you a per-slave "start" and "stop" script configuration specific for on-demand slaves.
Once installed, you will have an additional "Launch method" (1) for this case:
this one lets you specify the "Start" (2) and "Stop" (3) scripts, and on top of that you will be able to specify the "conventional" connection (4) method for reaching the slave after it has been started.
You will likely also want to specify that you want this node to be online only when Jenkins needs it (5).
The figure below shows the configuration that you may want to use if your on-demand slave is an Amazon EC2 instance.
NOTE: if your jobs need the slave to be up for being scheduled, you may end up in a situation where no jobs are scheduled because the slaves are offline, and the slaves are not started because no jobs are scheduled.
A common cause of this situation might be that you are polling Git by the Git plugin, and "Fast remote polling" (polling from the master instead of the slave) is disabled or not working. See the Git plugin documentation on how to get the "Fast remote polling" working.

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

About Maqetta
Maqetta is an open source technology initiative at
Dojo Foundation that
provides WYSIWYG tooling in the cloud for HTML5 (desktop and mobile).
Maqetta allows User Experience Designers (UXD) to perform drag/drop
assembly of live UI mockups.
One of Maqetta's key
design goals is to create developer-ready UI mockups that promote
efficient hand-off from designers to developers. The user interfaces
created by Maqetta are real-life web applications that can be handed off
to developers, who can then transform the application incrementally from UI
mockup into final shipping application. While we expect the
Maqetta-created mockups often will go through major code changes,
Maqetta is designed to promote preservation of visual assets,
particularly the CSS style sheets, across the development life cycle. As
a result, the careful pixel-level styling efforts by the UI team will
carry through into the final shipping application. To help with the
designer/developer hand-off, Maqetta includes a "download into ZIP"
feature to create a ZIP image that can be imported into a developer tool workspace (e.g., Eclipse).
For team development, Maqetta includes a
web-based review&commenting features with forum-style comments and
on-canvas annotations.
Maqetta came out of an internal IBM initiative to
address the visual design requirements of IBM's various UXD teams. IBM
contributed Maqetta's original code to open source to foster a community that can
help create and maintain a strong suite of open source HTML5
visual tools.
Key features:
- Maqetta provides a WYSIWYG visual page editor for drag/drop creation of actual running user interfaces (for both desktop and mobile UIs)
- For mobile visual composition, the user can use drag/drop authoring within an exact-dimension device silhouette, such as the silhouette of
an iPhone
- For early-stage mockups (both desktop and mobile), Maqetta provides a quick UI sketching feature where Maqetta works like a simple drawing tool,
where the user can create UI sketches using any combination of actual widgets, common UI clipart and
simple drawing tools (e.g., rectangles, ovals, lines, arrows)
- For an efficient designer/developer workflow, Maqetta provides export options that
allows Maqetta-created UI mockups into leading developer tools such as Eclipse
- Maqetta creates actually running HTML pages, and supports simultaneous HTML editing in either design or source views
- Maqetta includes deep support for CSS styling (the application includes a full CSS parser/modeler)
- The page editor includes a mechanism for organizing a UI prototype into a series of
"application states" (aka "screens" or "panels") which allows a UI design
to define interactivity without programming
- The application includes a web-based review and commenting feature where the
author can submit a live UI mockup for review by his team members
- The application includes a "wireframing" feature that allows UI designers to
create UI proposals that have a hand-drawn look
- Maqetta includes desktop and mobile theme editors for customizing the visual styling of a collection of widgets
- Maqetta's code base has a
toolkit-independent architecture that allows for plugging in arbitrary
widget libraries and CSS themes.

Pkgconfig module
This module is a simple generator for pkg-config files.
Usage
To use this module, just do: pkg = import('pkgconfig')
. The following function will then be available as pkg.generate()
. You can, of course, replace the name pkg
with anything else.
generate
The generated file's properties are specified with the following keyword arguments.
libraries
a list of built libraries (usually results of shared_library) that the user needs to link againstversion
a string describing the version of this libraryname
the name of this librarydescription
a string describing the libraryfilebase
, the base name to use for the pkg-config file, as an example the value oflibfoo
would produce a pkg-config file calledlibfoo.pc
subdirs
which subdirs ofinclude
should be added to the header search path, for example if you install headers into${PREFIX}/include/foobar-1
, the correct value for this argument would befoobar-1
requires
list of strings to put in theRequires
fieldrequires_private
list of strings to put in theRequires.private
fieldlibraries_private
list of strings to put in theLibraries.private
fieldinstall_dir
the directory to install to, defaults to the value of optionlibdir
followed by/pkgconfig
The results of the search are

with shape [N1, ..., Nn, K]
, we define
$$lbeta(x)[i1, ..., in] = Log(|Beta(x[i1, ..., in, :])|)$$.
In other words, the last dimension is treated as the z
vector.
Note that if z = [u, v]
, then
\(Beta(z) = int_0^1 t^{u-1} (1 - t)^{v-1} dt\), which defines the
traditional bivariate beta function.
If the last dimension is empty, we follow the convention that the sum over the empty set is zero, and the product is one.

You don’t have to delve too deep into learning HTML and CSS to start seeing the terms “id” and “class” being liberally thrown around. But what are they, and what do they do? Well to answer the first question, they’re both selectors; they perform similar jobs but in slightly different ways. As web developers we may not have hammers and nails to build our sites, but it’s just as important for us to know our way around the items in our toolbox. So what’s a newbie developer to do?
You’ll notice the class is applied to an element with class=”class-name-here” and denoted in the associated CSS file with a #hash. The id is slightly different - it’s written as id=”id-name-here” in the HTML, and marked with a .fullstop in the CSS file.
Okay, we know how to identify a class and an id. But how the heck do you use them in practice?
Well, the id is a bit of a prima donna. It only wants to talk to one element, and one element alone. The class on the other hand is a cheerful, outgoing soul – it can be applied to as many elements as you want!
Since ids are unique and demand to be treated with respect, it’s best to use them for situations where you only have a single instance within your code, like a header or footer. Classes, on the other hand, can be applied to things like photographs or blocks of text.
Even though ids don’t like to mingle with multiple elements, they’ll happily mix with classes so things like this are totally okay:
Classes can be used multiple times within a markup document, while ids – which carry more weight – can only be used once. When deciding whether to use a class or id, ask yourself whether it’s likely to be the only instance of that selector within your stylesheet. If it’s a photo or text styling, opt for a class. If it’s a navbar, header or footer, slap it with an id.
Regardless, the best way to get a handle on classes versus ids is to get out there and give it a crack.

Data transformation¶
The (element-wise) transformation of data is, together with filtering, at the very core of data flows and nuts-flow provides various nuts for this purpose.
Elementwise transformations¶
The most common transformation is the mapping of a function on a flow.
Map¶
Map(func)
nut takes a function and applies it to each element of
the input iterable. See the following examples: and
>>> from nutsflow import *
>>> from nutsflow import _
>>> Range(5) >> Map(lambda x : x * x) >> Collect()
[0, 1, 4, 9, 16]
>>> Range(5) >> Map(_ * 2) >> Collect()
[0, 2, 4, 6, 8]
>>> Range(5) >> Map(_ > 2) >> Collect()
[False, False, False, True, True]
>>> Range(5) >> Map(str) >> Collect()
['0', '1', '2', '3', '4']
Note that Map
can transform elements of the flow in arbitrary ways
but cannot change the number of elements in the flow.
MapMulti¶
Occasionally, it is necessary to apply different, independent mappings to the same data. One way is to process the data for each mapping individually, e.g.
>>> times2 = Range(5) >> Map(_ * 2) >> Collect()
>>> greater3 = Range(5) >> Map(_ > 3) >> Collect()
However, if the generation or reading of the input data is
computationally expensive it is more efficient to use MapMulti
and avoid rereading the input multiple times.
>>> times2, greater3 = Range(5) >> MapMulti(_ * 2, _ > 3)
>>> times2 >> Collect()
[0, 2, 4, 6, 8]
>>> greater3 >> Collect()
[False, False, False, False, True]
Note that MapMulti
performs an arbitray number of mappings
at the same time and returns iterators for each mapping.
Tabular data¶
Often input data is organized in rows (records) and columns, and transformations for selected columns only are needed.
MapCol¶
MapCol(columns, func)
maps a function to the specified
columns of the input data and leaves other columns unchanged.
Given the following table with tuples as records
>>> table = [ (1, 2),
... (3, 4) ]
the example flow below negates all numbers in column 0:
>>> negate = lambda x: -x
>>> table >> MapCol(0, negate) >> Print() >> Consume()
(-1, 2)
(-3, 4)
or let us convert each number in the second column to a string:
>>> table >> MapCol(1, str) >> Collect()
[(1, '2'), (3, '4')]
MapCol
can apply the same mapping to multiple columns at
the same time. For instance, checking if numbers in columns
0 and 1 are greater than two:
>>> table >> MapCol((0, 1), _ > 2) >> Collect()
[(False, False), (True, True)]
Note that input data must be an iterable of tuples or other indexable objects and the flow iterates over these records. To iterate over all elements of a table individually use Flatten.
Append¶
Append(items)
allows to append a single item or sequence
of items to the rows of the input data. For instance, given the
table above the following code adds an x to each row:
>>> table >> Append('x') >> Print() >> Consume()
(1, 2, 'x')
(3, 4, 'x')
Appending (or merging) a column or table is equally easy:
>>> new_col = ['a', 'b']
>>> table >> Append(new_col) >> Print() >> Consume()
(1, 2, 'a')
(3, 4, 'b')
>>> table2 = [ ('a', 'c'),
... ('b', 'd') ]
>>> table >> Append(table2) >> Print() >> Consume()
(1, 2, 'a', 'c')
(3, 4, 'b', 'd')
Insert¶
Insert(column, items)
operates just like Append
but allows
to specify the column where the new data is to be inserted:
>>> table >> Insert(1,'x') >> Print() >> Consume()
(1, 'x', 2)
(3, 'x', 4)
>>> table >> Insert(0,table2) >> Print() >> Consume()
('a', 'c', 1, 2)
('b', 'd', 3, 4)
Insert()
and Append()
are often useful to enumerate rows:
>>> table2 >> Insert(0, Enumerate()) >> Print() >> Consume()
(0, 'a', 'c')
(1, 'b', 'd')
Note the difference to using Zip
, which nests the data:
>>> table2 >> Zip(Enumerate()) >> Print() >> Consume()
(('a', 'c'), 0)
(('b', 'd'), 1)
Get¶
Get(start, end, step)
operates similar to Python’s slicing
[start:end:step]
and extracts individual elements or
slices from table records. For instance, given the following table
>>> table = [ (1, 2, 3),
... (4, 5, 6) ]
Get(1)
extracts all elements in column 1 of the table:
>>> table >> Get(1) >> Collect()
[2, 5]
Note that, since a single column was extracted, the output is a list of numbers and not a list of tuples anymore.
Get(0, 2)
extracts column 0 to 1:
>>> table >> Get(0, 2) >> Print() >> Consume()
(1, 2)
(4, 5)
and Get(0, 3, 2)
extracts column 0 to 2 with stride 2:
>>> table >> Get(0, 3, 2) >> Collect()
[(1, 3), (4, 6)]
Note that in agreement with Python’s slicing the index of the
end
column is exclusive.
GetCols¶
The Get
nut described above can extract only consecutive
table columns in order. GetCols(*columns)
allows to extract
arbitray columns in arbitrary order. Given the following table
>>> table = [ (1, 2, 3),
... (4, 5, 6) ]
GetCols(1)
extracts column 1 of the table:
>>> table >> GetCols(1) >> Collect()
[(2,), (5,)]
Note that in contrast to Get(1)
a list of (single element)
tuples is returned.
The following example extracts columns 2, 1, and 0, and effectively reverses the column order of the table:
>>> table >> GetCols(2, 1, 0) >> Print() >> Consume()
(3, 2, 1)
(6, 5, 4)
GetCols
can even duplicate columns, e.g. duplicating
column 1 and removing column 0 can be achieved as follows:
>>> table >> GetCols(1, 1, 2) >> Print() >> Consume()
(2, 2, 3)
(5, 5, 6)
Flatten data¶
Hierarchical data structures such as lists of lists frequently
need to be converted to flat structures. Flatten
and FlatMap
are two nuts for flatting data.
Flatten¶
Flatten
flattens all iterables within the input and returns
an iterator over the result. For instance:
>>> [(1, 2), (3, 4, 5), 6] >> Flatten() >> Collect()
[1, 2, 3, 4, 5, 6]
Note that only one level is flattend. Deeper structures remain unchanged
>>> [(1, 2), ((3, 4), 5), 6] >> Flatten() >> Collect()
[1, 2, (3, 4), 5, 6]
but can be, of course, flattend by sucessive calls of Flatten
:
>>> [(1, 2), ((3, 4), 5), 6] >> Flatten() >> Flatten() >> Collect()
[1, 2, 3, 4, 5, 6]
FlatMap¶
A common operation is a Map
followed by a Flatten
and FlatMap
is a nut that provides this operation in one call. See the following
examples to dublicate all numbers in a list of numbers:
>>> dup = lambda x: (x, x)
>>> [0, 1, 2] >> Map(dup) >> Collect()
[(0, 0), (1, 1), (2, 2)]
>>> [0, 1, 2] >> Map(dup) >> Flatten() >> Collect()
[0, 0, 1, 1, 2, 2]
>>> [0, 1, 2] >> FlatMap(dup) >> Collect()
[0, 0, 1, 1, 2, 2]

Xavier Defrang characterizes himself as a “…a frustrated Python-lover writing object-oriented PHP code”. He has contributed to the O’Reilly Python Cookbook and initiated the french translation of Dive Into Python. Despite his pythonic love, he has also managed to post the single most flattering article about Rails I’ve yet to stumble across in which he compares Ruby on Rails to Java, Python, and PHP.
The number of quotes and passages I want to pull out are so plentiful that I can hardly decide. Here goes a few:
- The recent Trails video walktrough just showed that J2EE zealots were definetly not getting it: the What is as important as the How
- I consider myself a real Pythonistas… and I’ve never thought of Ruby as attractive because of its syntax I (still) find a bit too sweet… But now that there is a killer app for Ruby which appears to square the circle of web development, can you think of a better time to look at it?
- I predict that a lot of high-profile PHP developers will soon or later switch to RoR. As a frustrated Python-lover writing object-oriented PHP code, Rails really fits as the best-of-both-world solution.
- The productivity boost offered by Rails is similar to what I experienced when switching from C++ to Python as my main development language.
Anyway, go read the whole thing before I reveal all of it through quotes.  Depending on your own personal enthusiasm about Rails :)

public abstract Bag adding(Object element) throws IllegalElementException
- Construct a new Bag that is a clone of self except
that it includes indicated element. This can be used
to create a series of Bag, each differing from the
other only in that they contain additional elements.
- Parameters:
- the - element to add to the new Bag
- Returns:
- the new Bag c, with the sameStructure as this except that
c.occurrencesOf(element) == occurrencesOf(element)+1
- Throws: IllegalElementException
- if !canInclude(element)

" Let your garden grow with our smart garden system! "
Nature and technology don't have to exist at odds with each other. In fact, similar smart home tech that automates your thermostat or your garage door can extend outside the walls of your house, helping you make your own corner of nature thrive.
Smart garden and lawn care tech encompasses plant sensors, weather monitors, sprinkler systems and even robot lawn mowers. The diversity is fitting for the great outdoors, but it can also make it difficult to know where to start.
Once you understand your options, you can stem your plant killing ways with push notifications, you can save time with automation, or you can simply collect data and monitor the conditions of your land. The diversity of smart garden tech will prove beneficial instead of daunting once you find the tools to fit your needs.
