New Yorker's Minimum Wage Future
By Giselle Vanegas
Gov. Andrew M. Cuomo said that in his State of the State he will propose making the minimum wage in New York among the highest in the country. Credit Victor J. Blue for The New York Times.
The minimum wage rate is the lowest hourly amount that can be paid to employees.
New York’s minimum wage has risen from $8 to $8.75 an hour, giving a boost in pay to some 700,000 workers.
The state is one of several raising its minimum pay rate in the new year, with increases taking effect Jan. 1 in Connecticut, Rhode Island, Massachusetts, Florida and other states.New York lawmakers approved the increase in 2013 as part of a series of steps to bring the wage to $9 on Dec. 31, 2015.
It could go up even higher if lawmakers pass another increase in the 2015 legislative session.Supporters of a higher minimum wage are calling for a $10.10-per-hour minimum and want to give cities like New York the authority to raise it even more.
Continuing to push for higher wages for the state's lowest-paid workers, Gov. Andrew M. Cuomo announced on Tuesday that all of the waiters, waitresses and others who work for tips in New YorkCity will soon get a raise of their minimum wage to $7.50 an hour. The state last increased the minimum wage in 2013, approving a three-year rollout that pushed the hourly rate to $8.75 from $7.25. That wage will rise to $9 an hour by 2016. But , Mr. Cuomo suggested that the rate of increase was too slow, saying “the wage gap has continued to increase.” Under his proposal, the wage would increase to $11.50 and $10.50 at the end of 2016.
The proposal, announced at a news conference in Manhattan, seemingly offered the governor a chance to refine his position regarding differing wages in differing parts of the state, noting it was the first time New York City would be allowed a different rate. Last year, Mr. Cuomo had dismissed suggestions that local governments could set their own minimum wages, saying that letting them do so could lead to a “chaotic situation.


Training and testing was performed on datasets containing three filters, five filters, and five filters plus a set of unfiltered images. All odd neighbor (k) values from 1-29 were evaluated to determine the value with optimal accuracy in each case. Various ratios of training to testing data were also experimented with. Optimal conditions were logged for each dataset tested.
Tested over order randomized datasets 3000 times.
Overall best: 98.90%
Best K Value: 7
Average: 95.22%
Spread: 11.40%
Overall best: 88.62%
Best K Value: 13
Average: 76.27%
Spread: 25.04%
Overall best: 78.52%
Best K Value: 17
Average: 67.89%
Spread: 21.47%
The most immediate source of error directly pertains to the training data available. Flickr does not indicate what filters have been applied to images automatically or after a user has enabled one, hence the opportunity to undertake this project. Filters must be attempted to be identified by eye and categorized as such. This proves a difficult task with more subtle or similar filters. This suspicion is substantiated by a high degree of accuracy when testing the most obvious and likely to be correctly identified filters in the three filter set.
An additional concession is inherently the color composition of the images in the datasets. While filters do heavily alter the HSV composition of images, darker or lighter images regardless of applied filter may already be more predisposed to being recognized as noir or bleached respectively, regardless of another filter being applied.

This is an opinionated transcription of Eric Johnson's talk Thinking Asynchronously. He has presented in the 2020 GOTO Conference, online edition because of COVID pandemic. His straightforward presentation approach guides us through steps that take advantage of asynchronous persistence pipelines to provide a better experience to our users. It is a great opportunity for newcomers to understand where AWS want to achieve with serverless from know on. I took the opportunity to elaborate more on a few services used by him on his talk to give more context.
Common Serverless Pattern
Usual serverless application will mimic the typical three-tier architecture. API layer will, as naturally happens, be responsible for Security and Routing, while compute layer will have anything else you need to persist your data into the storage layer. On Eric's perspective this comes with a concerning trade-off: if something goes wrong it will probably fail on your code as it is most vulnerable building block of your architecture.
Thinking Asynchronously
Eric proposes that we persist the data before we apply any computation to that. It brings us a few major benefit from the traditional approach:
- Greater reliability. In case of failure in our codebase, we have our data persisted already.
- Faster response times in our APIs. By moving the extra computation to a second step, the user already received the feedback in the UI.
- We can do more in less apparent time to the client. As the complex computing is now the last thing to do, our persistence pipeline has bigger room to process data with no apparent impact on user's experience.
One might argue that you can squish bits and bytes of your code to provide a similar result. Perhaps the pillars from Eric's approach lies on how it increases the flexibility by reducing the response time on the API side. After all, it's an old known fact that better response times implies better user experience.
Well, we talk about serverless we look at "what is serverless?" and basically I meant serverless is: something happens, we react and do something.
Event Driven Patterns
Event Driven Development is the key to make the suggested approach work. AWS-wise, there's a multitude of events that can you can listen to with a AWS Lambda function. Of course, you can also take advantage of AWS network services like SNS, SQS and Kinesis to consume asynchronous events on your Docker container or application instance.
Amazon API Gateway
I'd like to draw your attention to this versatile service available in AWS, and the idea behind its conception. API Gateway was first introduced in 2015, it communicates directly with 100+ AWS Services, allowing you to transform requests and response payloads with Apache Velocity templating language (VTL). It's commonly used as serverless Rest API, allowing developers to configure HTTP routes in a higher level abstraction in which you don't have to provision resources to handle the request - matching Eric's personal definition of serverless. Requests received by the API Gateway are translated into events, allowing you to listen it directly to any compatible AWS service, like DynamoDB or Lambda.
API Gateway is also a well known pattern. A few years ago, Netflix OSS team introduced their own API Gateway solution. It was designed with a few key philosophies in mind, "each of which is", in their words, "instrumental in the design of our new system":
- Embrace the Differences of the Devices
- Separate Content Gathering from Content Formatting/Delivery
- Redefine the Border Between “Client” and “Server”
- Distribute Innovation
In fact, the problem it solves is wide known between teams handling large fleet of microservices. GraphQL, for instance, approaches these problems from a different perspective, and has been in internal use on Facebook since 2012 as well. Since Netflix blog post, several other approaches have been designed at an alternative for the custom brewed API Gateway solution. Krakend is a fairly popular and feature rich stateless API Gateway - might be a good tool for those situations where the cost AWS API Gateway is an issue.
Amazon DynamoDB
DynamoDB is an underrated, fascinating database service. The description on its website doesn't make justice to its capabilities: 1
- Key-value data store - It fits perfectly as a persistence layer for tasks that requires intensive write throughput - being especially good for timeseries data or document persistence.
- Expirable entries - You can define a Time To Live (TTL) value to arbitrary expire entries on your tables.
- Global tables - DynamoDB can manage tables accessible (replicated) globally.
- In-memory Acceleration with DAX - It acts as a mix of near cache and table space for ly accessed data. Pricey, but might worth it if you take into account the cost of maintaining such a mechanism by your self.
Surely, DynamoDB's feature list is more extensive than that. But the ones above mentioned are ingredients for a multitude of scalable recipes for problems you might face on your daily routine. From The Poor Man's Event Sourcing Tool 2 to a Globally Distributed Ordered Queue, it is the kind of Swiss Knife you want to have on your toolbox when you have a complex situation to tackle. You can even create your ad-hoc scheduling mechanism, allowing you "to schedule an irregular point of time execution of a lambda execution without abusing CloudWatch crons".
Inevitably, its simple key-value design introduces trade-offs: indexing is quite limited, you can't join tables and you will probably spend a bit of time trying to fine-tuning it for an optimal cost its read and write provisioning 3. But its flexibility and simple API, along with thoughtfully designed persistence tables, might be an elegant and affordable solution for your company.
Other "storage first" options
Amazon EventBridge
This is another obscure but intriguing service available in the AWS portfolio. EventBridge is more than an old-fashion Service Bus, but a blistering fast decision tree capable to translate inputs into actions. It can connect with, basically, everything from AWS Lambda and AWS Step Functions to AWS Kinesis and AWS SQS. You even use AWS SNS to trigger a further HTTP request to an external service.
Lambda Destinations
With Destinations, you can route asynchronous function results as an execution record to a destination resource without writing additional code. An execution record contains details about the request and response in JSON format including version, timestamp, request context, request payload, response context, and response payload. For each execution status such as Success or Failure you can choose one of four destinations: another Lambda function, SNS, SQS, or EventBridge. Lambda can also be configured to route different execution results to different destinations.
-
"A fully managed proprietary NoSQL database service that supports key-value and document data structures. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second" - as was seen in the Amazon DynamoDB description page - 05/Jun/2020.
-
Depending on how you design your tables, TTL and stream listeners, it might be cheaper than spinning up and maintaining a Kafka cluster.
-
The pricing model is not the same pay-as-go that you find on most of AWS services, instead of paying for requests you pay for the provisioned read and write capabilities of your tables. It's true that, a long time ago, Amazon introduced auto-scaling capabilities for table provisioning, but still you have to keep its pricing model in mind otherwise you might run out of budget.
-
Eric's explanation about Lambda Destination: "There is this really cool thing we announced last Re:Invent called Lambda Destinations. And the way this works is I can run a function and if it is successful than I can just trigger some data into EventBridge, Lambda SNS or SQS. Or if it is on fail, I can then trigger data into the same data."

Troy Parrott Back In The Under 21s Squad For Massive Sweden Clash
by Michael McCarthyTroy Parrott wasn't used in the Aviva Stadium last night but might be on full display in Tallaght tonight instead.
Stephen Kenny has received a massive boost with the news that Parrott will be available to him for tonight's crucial U21 qualifier against Sweden.
Parrott was an unused sub for Mick McCarthy's seniors at the Aviva last night, freeing him up to be added to tonight's squad. The 17-year-old has scored three goals in his three games at U21 level.
It's not something that will please the Swedes. They took an early lead against Ireland in the reverse fixture in September, only for Parrott to be brought on, scoring two in a 3-1 win for Ireland.
Lee O'Connor already rejoined the squad earlier in the week after making his senior debut for Ireland against New Zealand on Thursday night.
Ireland sit top of the group on 13 points after six games, three ahead of Italy who've played two fewer games. Iceland, who inflicted Ireland's only defeat of the campaign are on nine points after five games while Sweden have six points, having only played three games. A win tonight will be a serious boost to Ireland's qualification hopes, putting some real distance between them and Sweden and Iceland. Ireland will host Iceland and travel to Luxembourg in March, before finishing the campaign in Italy next November.

Enumerable#map
January 18, 2015
Enumerable is an extremely useful Ruby module, or library of methods, that can be used across multiple classes - such as the Array class or Hash class. The Enumerable module enables programmers to cycle through various elements in collection objects like arrays and hashes, and perform various actions to each object within the collection. These methods can produce much simpler versions of other looping options, and can also perform more specific repeated tasks in an elegant way.
The Enumerable method I would like to focus on in this post is Enumerable#map. To preface my explanation of this method, here is a simple example of how it works:
example: arr = [1,3,5]
arr.map { |n| n * n }
returns the new array [1, 9, 25]
Enumerable#map, as seen above, enables the creation of a new array which has been modified in a way specified by the programmer. It can either be thought of as performing a certain action and collecting the results, as in the similar #collect method, or as "re-mapping" the original object (|n| in our example), and producing a new array of changed versions of the original object. The new array is filled with whatever is returned by the block each time it runs - for each object in the collection object.
This method and the concept of enumerators can be intimidating at first, but the methods in the Enumerable module are fairly intuitive and extremely useful once you realize that they are simply a form of going through each element in a collection object and performing a certain task to each object.

Dear Sir,
I would like to know how can I use searchcombinators in my
multi-objective model in FlatZinc.
I have 2 objectives. I minimize the first and I reuse the solution for
the minimization of the second objective.
Can you give me the good syntax in FlatZinc with searchcombinators to
do that please ?

Once you have your notebook open, you may skip to the next page of this tutorial.
If you prefer to work on your local machine, you can install the nbinteract
package. To install the package, you must first have
Jupyter Notebook installed. Then, run:
pip install nbinteract
# The next two commands can be skipped for notebook version 5.3 and above
jupyter nbextension enable --py --sys-prefix bqplot
jupyter nbextension enable --py --sys-prefix widgetsnbextension
Then, start your Jupyter notebook server using
jupyter notebook
Create a new notebook called tutorial.ipynb
(we will use this filename in
later parts of this tutorial).


Code set here is bundled directly into the Adobe Launch library JS file and can thus run immediately.
The code is provided with two arguments: event, target
this is set to the triggering element, where the listener is registered. Defaults to window.
target refers to the
actual element clicked.

Toolbar Buttons is the single biggest button pack for Firefox or Thunderbird there is. There are now nearly 150 Firefox and 100 for Thunderbird. You will find buttons that enable hidden functionality or is too many clicks away, but some of the best buttons are those unique to the extension. For example from some of out most popular buttons, there are menu items for, Options, Bookmark Manager, Bookmark Page, and Add-ons, but for Snap Back, Restart and about:config there is no existing user interface. There have been nearly 2 million downloads to date.
To find out more information about each of the buttons, please see our Button List which has descriptions of all the buttons.
Once installed to get started using the buttons open the Customize Coolbar window by either right clicking on the toolbar and selecting Customize from the pop up menu or going View then Toolbars then Customize and from the window that opens up you can drag the buttons to your toolbar.

T
- the type of values written to the sink.@Experimental(value=FILESYSTEM) public abstract class FileBasedSink<T> extends java.lang.Object implements java.io.Serializable, HasDisplayData
At pipeline construction time, the methods of FileBasedSink are called to validate the sink
and to create a FileBasedSink.WriteOperation
that manages the process of writing to the sink.
The process of writing to file-based sink is as follows:
In order to ensure fault-tolerance, a bundle may be executed multiple times (e.g., in the
event of failure/retry or for redundancy). However, exactly one of these executions will have its
result passed to the finalize method. Each call to FileBasedSink.Writer.openWindowed(java.lang.String, org.apache.beam.sdk.transforms.windowing.BoundedWindow, org.apache.beam.sdk.transforms.windowing.PaneInfo, int)
or FileBasedSink.Writer.openUnwindowed(java.lang.String, int)
is passed a unique bundle id when it is called
by the WriteFiles transform, so even redundant or retried bundles will have a unique way of
identifying
their output.
The bundle id should be used to guarantee that a bundle's output is unique. This uniqueness
guarantee is important; if a bundle is to be output to a file, for example, the name of the file
will encode the unique bundle id to avoid conflicts with other writers.
FileBasedSink
can take a custom FileBasedSink.FilenamePolicy
object to determine output
filenames, and this policy object can be used to write windowed or triggered
PCollections into separate files per window pane. This allows file output from unbounded
PCollections, and also works for bounded PCollecctions.
Supported file systems are those registered with FileSystems

 The mannerisms are built in, but they can overtake performers. As with Ann-Margret in the 1984 TV version: hers the old community playhouse try, you keep rooting for her even though you know the part's much too large and too grandly maddening for a pop star as sometimes actress. While amazingly watchable as the whoriest version--she does a quite fine attempted seduction of the young bill collector, delivering with slutty exactitude, "You make my mouth water," and, "I've got to be good and keep my hands off children,"--she can't get the flowery language to blossom; she hasn't the power or range to bring pained dignity and restraint to the blooming insanity. Respectable and respectful as she is, at her most dramatic she sounds like Betty White's Ellen in "Mama's Family," only more shrill, and she can't elicit what's mandatory--commiseration for Blanche. The audience has to sense that Blanche, right from the start, is walking a tightrope between crushing realism and magic; in order for the part to get to us, we have to feel her desperation for the latter.
Jessica Lange's interpretation of Blanche in the 1995 CBS Playhouse 90 revival starts out as a super wallow of actressey schtick: the constant hands to the hair, chest and mouth, the twisting and pulling of the hankies. It's already too much and we haven't even gotten to the showier numbers. What saves her at the beginning is that we can hear echoes of Vivien Leigh's incomparable vocal ability to catch the rhytm and flourishes of Williams' floridness. Accidental lift as homage perhaps, but we're sure glad it's there. Not until roughly ninety minutes into the play does Lange finally move into Blanche: looking like the sister Tuesday Weld never told us about, she's sensational--and later, when thinking over the performance, haunting--in her disquieting quiet when she tells John Goodman's Mitch about her husband's suicide. She gets deep into Williams territory--his specialty of exposing torment and vulnerability through poetic dissipation. She manages more compassion for Blanche than Ann-Margret, and we can feel the pain of her embarrassment in the realization that she's got to exit passed Stanley and Mitch on her way to the loony bin, but the tragedy gets squelched. Part of this has to do with the way CBS inexcusably jumped to commercial after the rape, which lessened the impact considerably. Part of it may be that Alec Baldwin's Stanley is too elementarily defined--that is, his motives get rattled off a, b, c--and therefore whatever mystery lurks within his brutish ape is terminated. But mostly, I think, Lange's Blanche is demonstrative challenge as actress, and not a totally successful inward reach for the character. Touching greatness at the conclusion of scene seven, and again during the final, Lange eludes triumph because she's reliant on all the externals.
Yet in spite of the quibbles, the misgivings, I can't get Lange out of my mind. Weeks later and her scenes unexpectedly pop into memory. If it hadn't been for the notes I took about Ann Margret's Blanche, I mightn't have remembered much. But I do recall Leigh's performance--unforgettable in its anguish and slowly revealed nutsiness. The most demanding of Williams' female characters may require that the actresses playing them also be a little gone. It's certainly the key to Leigh's landmark portrayal in Eliza Kazan's 1951 movie. And Geraldine Page's SWEET BIRD OF YOUTH and SUMMER SMOKE and Katherine Hepburn's Mrs. Venable in SUDDENLY, LAST SUMMER wouldn't have been nearly as effective without their imperial, theatrical neuro-kinesthesia.  She faked it in FRANCES, a somber, cloudy hodgepodge of SNAKE PIT psychotics and queasy, Reaganesque anti-Communist politics, but she wasn't ready for the assumed depth: looking hardened from the insulin and shock therapies and eventual lobotomy, she couldn't act it. At the end, when Frances appears on "This is Your Life" as an ad for the wonders of hocus pocus psychiatry, she's give an odious consolation prize for all that she suffered--an Edsel; but having to show the difference between the fiery actress locked up against her will and the mental somnambulist she became, Lange can't bring a convincing emptiness because it was already there at the start. She's much more persuasive as Carly in Tony Richardson's BLUE SKY.
A sort of trial run to Blanche--she says to a commander's spouse, "A woman's charm is mostly illusion"--Carly is wife to lifer Tommy Lee Jones, and the ravages of inconstancy, the relentless vagabonding from one base sight to another throughout the years has made her not insane but a little cracked. Her daydreams of wanting to be another Ava torreroing in THE BAREFOOT CONTESSA or a Marilyn wowing the guys in a SEVEN YEAR ITCH dress are her defense mechanism against the dreariness of military living; her bold, flirtatious dancing a plea for attention and physical need. She's longing for escapist fun: when the commander's wife speaks about a base sho w she and the other wives are putting on, Carly festively giggles, "Do you need any dancers?" Unfortunately, the script gets soggy with social, environmental and moral consciousness--Tommy Lee Jones suffers the after-ef fects of post-military McCarthyism--and the movie loses some staying power. But Lange hangs in, valiantly giving credence to the melodrama. And showing that she can do edge: pitching a fit over the dump she has to make a home, she runs to the family car, smashes into a jeep and ends up at a PX, almost losing control as she touches and unravels bolts of fabric. Her despairing leads her to unintentionally victimize Tommy, but, of course, she finally gathers her wits, and, at end, dragging it up as Liz's Maggie from CAT ON A HOT TIN ROOF, she gets her Brick back and her smile as she exits the base is as wide as the convertible she's beaming in. Carly's mildly dotty but not unhinged; she's able to use her flightiness as weapon without embarrassment.
Not long after making BLUE SKY, ready to tackle a real loon, Lange opened on Broadway with STREETCAR, to a less than enthusiastic reception. Having seen only clips from the box, I can guess why: she was showing the labors of effort--the tricks, tics--and hoping to catch the essence of Blanche in the process. However, friends who saw her toward the end of the 160 performance run say that she seemed to get transfixed, becoming almost motionless before them, and they felt a foreboding about her--about Lange, not Blanche. The thrill of watching her, said one, was "in whether she'd lose it completely. She wasn't Blanche, she was possessed by Blanche." In the April, 1995 edition of US, Lange admitted to being swept away. "Sometimes I'd just sit on the floor and weep. I felt so alone, I felt so incredibly alone. After finishing the run of the play, I actually missed Blanche. It was a visceral sensation. Oh, I miss her so much." (Her kids would know when she was in her Blanche mode at home, complaining that she was in the tub again, with the lights low.) Lange's still seized by Blanche for the TV version. She said, "If you want to talk about the spine of the character, of course, I think it's really about aloneness. Wanting to be able to stop all of this finally. To find a place to fit in. Blanche says, 'I want to rest.' I always think that's the key...She can never rest. Physically or emotionally, mentally, spiritually." And that's central to Lange's portrayal--she never stops. And it is her exhaustion, on top of Blanche's and ours, that makes us give in the inevitable conclusion--that the only way for this Blanche to find rest is to be put to rest. It's likely that the drainage is what keeps us from responding less to Lange than we do with Leigh--that is, the cumulative effect is in effect a wipeout; we're so tired by the transfixion that we're relieved to see Lange's Blanche fyked off. Leigh's Blanche achieves something pitifully supernal: we know she needs the rest cure, but her "aloneness," that which makes her so different from her sister Stella, from everyone, is what will never give her peace, because she is not of this realm. But Leigh's private agonies joined with Williams' semi-self portrait (he saw himself more as Blanche than any other character he wrote) as if an ethereal fusion of souls. We're watching the real thing --a real disintegration.
Lange's no stranger to Williams. She played Maggie to Tommy Lee Jones' Brick in a 1984 TV version that was very faithful to the original play--text-wise. But when things go wrong in bringing Williams back as reverent stage or film revivals, they can go terribly wrong. Treating his text as sacred, playing without cuts, the 50s-style word heaps sound arched, faked, and--because so many of the actors in the revivals lack tonal poetry--induce sleepiness. As Maggie, Lange is so bad she's beyond laughter; one minute she's Tuesday Weld, the next Geraldine Page, minutes later she's Page doing Weld, and then vice versa. She causes self-willed atrophy; we lapse into vegetation, trying not to listen to all the blabber. (This happened to Natalie Wood as well, playing Maggie to husband Robert Wagner's Brick.) With his pocked, savaged face, Jones might look like a candidate for homo hanky hanky with Skipper--something we reject in Paul Newman, and ridicule in Wagner--but he exposes more than the others how under-developed Brick as character is. (It is irony that it took a strong, solid male presence like Newman to bring weak, booze-soaked Brick to movie life; and it's certainly Williams good luck that mostly good to great actors on stage and in the movies played his lead male characters, almost all of them weaklings.)
But Blanche, like Martha in Albee's WHO'S AFRAID OF VIRGINIA WOOLF? and Mary in O'Neill's LONG DAY'S JOURNEY INTO NIGHT, is a test of an actress's mettle. It takes courage to be play a role that strips you of the protections of vanity, especially when vanity is all the character has before being raped of it. While many of Williams' women border on the seriocomic, deifying as well as mocking matriarchalism and femininity, endlessly searching for magic but for the most part trapped by male-dominated reality, Blanche is finally destroyed by the realism of an act she may have envisioned as a delusional seduction--that Stanley would succumb to her charms. It's true that Williams wrote himself into Blanche, admitting that "we're both hysterics ... lascivious, demonic," and that both were raped ("I had a very attractive ass," he told Playboy, "people kept wanting to f... me."). It's also true that Blanche's instability comes out of his sister's tragic mental history--she was lobotomized, a fate that may befall Blanche. And during the writing of STREETCAR, originally entitled THE POKER NIGHT, Williams was involved with a male lover who became the basis for Stanley. (A Stanley-like scene: this lover would one day rage at Williams and throw his typewriter out a hotel window.) Though Williams wouldn't come to realize it until years later, Blanche's end was premonition: sloshed and incapacitated on booze and pills, embittered by an unfeeling, foolish press and unappreciating Broadway, Williams would for a time be institutionalized against his will. So watching Lange (and Ann-Margret) get carted off has an unintended, heartbreaking resonance for us now--a reminder of an author's demise, one he never deserved: that even after A STREETCAR NAMED DESIRE, A CAT ON A HOT TIN ROOF, after so many other hours of transport, he was considered only as good as his last hit. (Is Gabriel Garcia Marquez less of a master craftsman because he can't top ONE HUNDRED YEARS OF SOLITUDE?) While director Glenn Jordan could have achieved for Lange a larger degree of greatness had he not permitted the excesses of her affectations, providing instead a stronger confidence within herself, what may matter more is that Lange's Blanche reminds us and reinforces what Williams is often forgotten as--the female soul of American theatre.

It's time we talked about the elephant in the room.
Low-code products have been built the same way for almost 15 years. While they are great for businesses to accelerate the development of simple apps, they quickly begin to fall apart as those apps get adopted.
They say "Pro Dev Friendly," "No Limits," and "Never Hit a Wall."
The elephant? We all know that's not true.
I've been to business, low-code, and analyst conferences. I've been on hundreds of phone calls with users, and when talking with people who have already adopted low-code, all of them were disappointed.
- We did hit a wall quickly.
- I felt like I was having to say No to our users more often than I'd like when they asked for feature requests.
- We're jumping ship; low-code didn't work for us because we need <insert special feature here>.
It seems no one was actually fighting for the low-code users. Instead,Low-code vendors have just perfected the art of selling an unattainable dream, selling the benefits to business leaders but short-changing the actual development teams and treating them as secondary.
❤
At Ionic, we've been an open source, pro-developer company for over 7 years now. We always fight for the developer AND the company to provide better apps that enable them to accomplish their goals.
So while we've already helped thousands and thousands of companies build full-code apps, combined with our history of building drag-and-drop tools, we thought "Why not us?"
Why couldn't WE fight for low-code users and developers
So what would it look like?
A platform fully based on open source technology, Ionic provides a robust set of components meticulously crafted for performance and usability, easy connections to your data, empowerment of the developers to truly program anything.
"Yah, yah, but why should I believe you instead of those other guys? They're Pro Dev friendly!"
One reason.
We acknowledge that you'll always need to build something special for an app, there will always be that "one thing" that your users need that the low-code platform doesn't provide. So instead of trying to hide that, we embrace it.
Everything our platform provides works on the code as the source-of-truth. What does that mean?
It means you can pop open the hood, and edit any code you'd like, and the Low-code tooling will continue to work!
So go ahead, start with low-code. Connect to all of your data, rip it open, and have your pro devs program that one amazing feature that makes your app truly impact the business, using technology they already know and love (there are millions of devs familiar with our tech already).
Simply put: code matters.
We believe you should adopt low-code to move faster, but you should also have an amazing developer experience to go along with it.
Are you with me?

Did you see the patterns talk at the Plone Conference in Arnhem 2012? Here are the slides that were used for the demonstration.
View slidesPatterns is a combination of a library and a workflow. That workflow goes something like this:
-
The designer creates an HTML5 prototype. By including Patterns library, they can use a series of rich interaction patterns by applying dedicated classes and data-attributes instead of writing JavaScript. The prototype contains examples of all important page types with working interaction patterns such as form elements, modal panels, and AJAX injections.
-
Now the designer can validate a rich prototype with both the business stakeholders and the developers. All possibilities and impossibilities will become apparent before anything is built. This will prevent a lot of change requests and headaches during the development phase.
-
The designer hands the prototype over to the developers who copy most of the HTML over into their own templates. By doing that, all the interaction patterns already work as implemented by the designer. In some cases, the developers can write some extra JavaScript, or apply some patterns on their own, as a prototype is never fully complete.
For changes to an existing design, the process will look more or less the same, except everything will likely happen in shorter iterations and more in parallel.
Demos
Pattern indexGot it? Get it!
There are three ways of getting patterns into your site or prototype. You can download the patterns package and host it from your own server, or include it hosted from our server. It's up to you what you find easiest.
1. Hosted externally
To use patterns hosted externally, just paste the following line into your HTML:


A string S consisting of N characters is considered to be properly nested if any of the following conditions is true:
- S is empty;
- S has the form "(U)" or "[U]" or "{U}" where U is a properly nested string;
- S has the form "VW" where V and W are properly nested strings.
For example, the string "{[()()]}" is properly nested but "([)()]" is not.
Write a function:
def solution(S)
that, given a string S consisting of N characters, returns 1 if S is properly nested and 0 otherwise.
For example, given S = "{[()()]}", the function should return 1 and given S = "([)()]", the function should return 0, as explained above.
Assume that:
- N is an integer within the range [0..200,000];
- string S consists only of the following characters: "(", "{", "[", "]", "}" and/or ")".
Complexity:
- expected worst-case time complexity is O(N);

What is Decred?
Decred is a decentralized, autonomous digital currency governed directly by its voting stakeholders.  Decred is self-funded by a portion of the block reward.
Why is Decred needed?
Decred was born from its founders’ experiences with Bitcoin’s governance. Company 0 developed a Bitcoin full node implementation called btcsuite, but the software was not well received by the Bitcoin Core development team. With Bitcoin, the Core developers and Proof-of-Work miners are strong, centralized constituencies that can effectively veto changes to the consensus rules — other stakeholders in the Bitcoin ecosystem have minimal influence. The absence of a clear method for making decisions results in protracted disputes and chain splits, whereby a sub-community breaks off and creates an alternative version of the currency. This weakens the network effects and dilutes the project’s resources. Bitcoin also has a funding problem, which has been addressed with venture capital investment, bringing with it conflicts of interest. Decred is a better cryptocurrency because it addresses these shortcomings.
How does Decred work?
Decred iterates on Bitcoin by employing an innovative hybrid Proof-of-Work (PoW)/Proof-of-Stake (PoS) system and Politeia governance platform to solve the issues of centralization, funding, and governance. In Decred’s hybrid system, PoW acts similarly as with Bitcoin, but miners only receive 60% of the block reward. Thirty percent of the Decred block reward goes to PoS voters who quality control the miners’ work, reducing the power of the miners, putting power in the hands of the coin holders, and securing the network. The final 10% of the block reward goes into the Treasury to fund development and operations. The self-funding element ensures that Decred is sustainable over the long term.
The most powerful differentiator of Decred are its governance mechanisms, including Politeia. Everyone is welcome to contribute thoughts and ideas informally on its discussion platforms and social media, but formal decisions are made in Politeia by those who contribute through PoS.
Decred holders participate in PoS voting by time-locking (staking) funds in exchange for tickets. Tickets confer voting rights, and ticket voting determines:
- Consensus rule changes (on-chain)
- Validation of PoW miners’ work
- Treasury project funding (Dev work, communications, events, research, etc.)
- Policy (Constitutional amendments, procedures, standards, etc.)
The time-locking mechanism ensures that voters have “skin in the game”, and the PoS portion of the block reward incentivizes staking and active participation in the governance model. Decred seeks to attract intelligent investors who are interested in actively participating in our self-funding, decentralized, self-governing project.
“Best-in-class governance paired with perpetual funding and an open and collaborative environment with users and developers is the DNA that could achieve a breakthrough in blockchain development. If Decred can achieve this, it can not only become one of the major cryptocurrencies, but a much richer core chain with a thriving ecosystem around it.”
Decred launched in February 2016. There was no ICO or venture capital funding-Company 0 self-funded Decred’s development for two years. At launch, 8% of the total supply was pre-mined, with 4% used to compensate the developers (at a rate of $0.49 per DCR), and 4% air-dropped to 2,972 people who signed up (each received<PHONE_NUMBER>4 DCR).
Early on, the project focused on implementing the process to amend the consensus rules. The first changes were adopted was approved by ticket-voters in June 2017, marking the first time any cryptocurrency upgrade was deployed automatically following a user voting approval process.
With on-chain consensus rules working, Decred’s shifted focus to building Politeia, its platform for managing policy and budget. Politeia was launched in October of 2018, and marks a major milestone in the road to a fully decentralized, autonomous organization.
The project Treasury has been preserved by the custodians to this point, with a belief that major expenditures should wait until they can be formally approved by stakeholders in Politeia. The result is a Treasury greater than 570K DCR, worth more than $20 million at October 2018 prices.
Decred is poised to accelerate its development, in the direction set by its stakeholders. The treasury’s large balance will amplify the effect of DCR price increases on its spending power, and its continual replenishment means that long-term developer support is guaranteed. Current projects and proposals include privacy upgrades, support for Lightning Network, an expanded communications plan, and a decentralized exchange.
“Remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed—underscoring that the Decred team and contributors are all about doing the right thing for long-term (as manifested in their constitution for the project).”
How is work on Decred organized?
Decred uses a novel autonomous contractor model that allows for new individuals, groups, and companies to be paid for contributing to the project. Decred’s longstanding developers are open source software veterans and enthusiasts, and so Decred’s way of organizing and funding development is designed to fit with the open source ethos. Autonomy of contributors and meritocracy are the key principles around which work on Decred is organized.
Decred’s treasury funds are purely for the advancement of the project, free of any other constraints. It is unprecedented for open source projects to have access to this kind of funding. One of the big advantages of commons-based peer production is that contributors can efficiently select pieces of work that fit with their skills and interests. Decred aims to unlock the true potential of this approach by developing a funding model tailored to this new way of working.
- 36+ developers who contribute new code, maintain current code, and implement roadmap features in Decred’s open source software repositories.
- 15 contributors to maintaining and developing various community and media channels.
- 4 marketing professionals who handle event organization, public relations, and digital marketing.
- 9 designers who work alongside the developers and marketing contractors to develop solutions in disciplines of (1) UX/UI, (2) identity, and (3) visual communications.
Decred in Q4 2018
SPV Wallet Support — Instead of taking the typical wallet service approach where wallets connect to a centralized server, we have added support for a proper SPV mechanism that uses compact filters and works over the P2P network, an approach which does more to protect the privacy of users.
Network Security — A large number of ASIC manufacturers have released or announced ASICs for Decred in 2018, and the network’s PoW hashrate has increased from around 300 Thash/s in September 2017 to over 100,000 Thash/s in September 2018 - a 333x increase.
Politeia — Decred’s governance proposal submission, discussion, and voting platform is almost ready to go live. Politeia is built around the concept of transparent censorship, giving users who are censored the power to prove what was censored and hold administrators accountable. This robust public record of governance proceedings provides a solid foundation upon which to build up the Decred Decentralized Autonomous Organization which will ultimately govern the treasury and the project’s direction.
Lightning Network — Lightning Network support is being developed. The two projects’ respective lead developers work closely together — LND and Decred are based on btcsuite, which was also developed by Decred’s founding developers.
Enhanced User Privacy — This highly anticipated project within the Decred community has been kept under wraps thus far, however the details and an initial implementation are expected to be revealed soon.

8.5 CanvasWhen it comes to graphics, the Tkinter Canvas widget is the most free-form device in the library. It's a place to draw shapes, move objects dynamically, and place other kinds of widgets. The canvas is based on a structured graphic object model: everything drawn on a canvas can be processed as an object. You can get down to the pixel-by-pixel level in a canvas, but you can also deal in terms of larger objects like shapes, photos, and embedded widgets. 8.5.1 Basic Canvas OperationsCanvases are ubiquitous in much nontrivial GUI work, and we'll see larger canvas examples show up later in this book under the names PyDraw, PyView, PyClock, and PyTree. For now, let's jump right into an example that illustrates the basics. Example 8-13 runs most of the major canvas drawing methods. Example 8-13. PP2E\Gui\Tour\canvas1.py# demo all basic canvas interfaces from Tkinter import * canvas = Canvas(width=300, height=300, bg='white') # 0,0 is top left corner canvas.pack(expand=YES, fill=BOTH) # increases down, right canvas.create_line(100, 100, 200, 200) # fromX, fromY, toX, toY canvas.create_line(100, 200, 200, 300) # draw shapes for i in range(1, 20, 2): canvas.create_line(0, i, 50, i) canvas.create_oval(10, 10, 200, 200, width=2, fill='blue') canvas.create_arc(200, 200, 300, 100) canvas.create_rectangle(200, 200, 300, 300, width=5, fill='red') canvas.create_line(0, 300, 150, 150, width=10, fill='green') photo=PhotoImage(file='../gifs/guido.gif') canvas.create_image(250, 0, image=photo, anchor=NW) # embed a photo widget = Label(canvas, text='Spam', fg='white', bg='black') widget.pack() canvas.create_window(100, 100, window=widget) # embed a widget canvas.create_text(100, 280, text='Ham') # draw some text mainloop() When run, this script draws the window captured in Figure 8-21. We saw how to place a photo on canvas and size a canvas for a photo earlier on this tour (see Section 7.9 near the end of Chapter 7). This script also draws shapes, text, and even an embedded Label widget. Its window gets by on looks alone; in a moment we'll learn how to add event callbacks that let users interact with drawn items. Figure 8-21. canvas1 hardcoded object sketches8.5.2 Programming the Canvas WidgetCanvases are easy to use, but rely on a coordinate system, define unique drawing methods, and name objects by identifier or tag. This section introduces these core canvas concepts. <IP_ADDRESS> CoordinatesAll items drawn on a canvas are distinct objects, but they are not really widgets. If you study the canvas1 script closely, you'll notice that canvases are created and packed (or gridded or placed) within their parent container just like any other widget in Tkinter. But the items drawn on a canvas are not -- shapes, images, and so on are positioned and moved on the canvas by coordinates, identifiers, and tags. Of these, coordinates are the most fundamental part of the canvas model. Canvases define an (X,Y) coordinate system for their drawing area; X means the horizontal scale, Y means vertical. By default, coordinates are measured in screen pixels (dots), the upper-left corner of the canvas has coordinates (0,0), and X and Y coordinates increase to the right and down, respectively. To draw and embed objects within a canvas, you supply one or more (X,Y) coordinate pairs to give absolute canvas locations. This is different than the constraints we've used to pack widgets thus far, but allows very fine-grained control over graphical layouts, and supports more freeform interface techniques such as animation.[2]
<IP_ADDRESS> Object constructionThe canvas allows you to draw and display common shapes like lines, ovals, rectangles, arcs, and polygons. In addition, you can embed text, images, and other kinds of Tkinter widgets such as labels and buttons. The canvas1 script demonstrates all the basic graphic object constructor calls; to each, you pass one or more sets of (X,Y) coordinates to give the new object's location, start and end points, or diagonally opposite corners of a bounding box that encloses the shape: id = canvas.create_line(fromX, fromY, toX, toY) # line start, stop id = canvas.create_oval(fromX, fromY, toX, toY) # two opposite box corners id = canvas.create_arc( fromX, fromY, toX, toY) # two opposite oval corners id = canvas.create_rectangle(fromX, fromY, toX, toY) # two opposite corners Other drawing calls specify just one (X,Y) pair, to give the location of the object's upper-left corner: id = canvas.create_image(250, 0, image=photo, anchor=NW) # embed a photo id = canvas.create_window(100, 100, window=widget) # embed a widget id = canvas.create_text(100, 280, text='Ham') # draw some text The canvas also provides a create_polygon method that accepts an arbitrary set of coordinate arguments defining the end-points of connected lines; it's useful for drawing more arbitrary kinds of shapes composed of straight lines. In addition to coordinates, most of these drawing calls let you specify common configuration options, such as outline width, fill color, outline color, and so on. Individual object types have unique configuration options all their own too; for instance, lines may specify the shape of an optional arrow, and text, widgets, and images may all be anchored to a point of the compass (this looks like the packer's anchor, but really gives a point on the object that is positioned at the (X,Y) coordinates given in the create call; NW puts the upper-left corner at (X,Y)). Perhaps the most important thing to notice here, though, is that Tkinter does most of the "grunt" work for you -- when drawing graphics, you provide coordinates, and shapes are automatically plotted and rendered in the pixel world. If you've ever done any lower-level graphics work, you'll appreciate the difference. <IP_ADDRESS> Object identifiers and operationsAlthough not used by the canvas1 script, every object you put on a canvas has an identifier, returned by the create_ method that draws or embeds the object (what was coded as "id" in the last section's examples). This identifier can later be passed to other methods that move the object to new coordinates, set its configuration options, delete it from the canvas, raise or lower it among other overlapping objects, and so on. For instance, the canvas move method accepts both an object identifier and X and Y offsets (not coordinates), and moves the named object by the offsets given: canvas.move(objectIdOrTag, offsetX, offsetY) # move object(s) by offset If this happens to move the object offscreen, it is simply clipped (not shown). Other common canvas operations process objects too: canvas.delete(objectIdOrTag) # delete object(s) from canvas canvas.tkraise(objectIdOrTag) # raise object(s) to front canvas.lower(objectIdOrTag) # lower object(s) below others canvas.itemconfig(objectIdOrTag, fill='red') # fill object(s) with red color Notice the tkraise name -- raise by itself is a reserved word in Python. Also note that the itemconfig method is used to configure objects drawn on a canvas after they have been created; use config to set configuration options for the canvas itself. The best thing to notice here, though, is that because Tkinter is based on structured objects, you can process a graphic object all at once; there is no need to erase and redraw each pixel manually to implement a move or raise. <IP_ADDRESS> Canvas object tagsBut it gets even better: In addition to object identifiers, you can also perform canvas operations on entire sets of objects at once, by associating them all with a tag , a name that you make up and apply to objects on the display. Tagging objects in a Canvas is at least similar in spirit to tagging substrings in the Text widget we studied in the prior section. In general terms, canvas operation methods accept either a single object's identifier or a tag name. For example, you can move an entire set of drawn objects by associating all with the same tag, and passing the tag name to the canvas move method. In fact, this is why move takes offsets, not coordinates -- when given a tag, each object associated with the tag is moved by the same (X,Y) offsets; absolute coordinates would make all the tagged objects appear on top of each other instead. To associate an object with a tag, either specify the tag name in the object drawing call's tag option, or call the addtag_withtag(tag, objectIdOrTag) canvas method (or its relatives). For instance: canvas.create_oval(x1, y1, x2, y2, fill='red', tag='bubbles') canvas.create_oval(x3, y3, x4, y4, fill='red', tag='bubbles') objectId = canvas.create_oval(x5, y5, x6, y6, fill='red') canvas.addtag_withtag('bubbles', objectId) canvas.move('bubbles', diffx, diffy) This makes three ovals and moves them at the same time by associating them all with the same tag name. Many objects can have the same tag, many tags can refer to the same object, and each tag can be individually configured and processed. As in Text, Canvas widgets have predefined tag names too: tag "all" refers to all objects on the canvas, and "current" refers to whatever object is under the mouse cursor. Besides asking for an object under the mouse, you can also search for objects with the find_ canvas methods: canvas.find_closest(X,Y), for instance, returns a tuple whose first item is the identifier of the closest object to the supplied coordinates -- handy after you've received coordinates in a general mouseclick event callback. We'll revisit the notion of canvas tags by example later in this chapter (see the animation scripts near the end if you can't wait). Canvases support additional operations and options that we don't have space to cover here (e.g., the canvas postscript method lets you save the canvas in a postscript file). See later examples in this book such as PyDraw for more details, and consult other Tk or Tkinter references for an exhaustive list of canvas object options. 8.5.3 Scrolling CanvasesAs demonstrated by Example 8-14, scrollbars can be cross-linked with a canvas using the same protocols we used to add them to listboxes and text earlier, but with a few unique requirements. Example 8-14. PP2E\Gui\Tour\scrolledcanvas.pyfrom Tkinter import * class ScrolledCanvas(Frame): def __init__(self, parent=None, color='brown'): Frame.__init__(self, parent) self.pack(expand=YES, fill=BOTH) # make me expandable canv = Canvas(self, bg=color, relief=SUNKEN) canv.config(width=300, height=200) # display area size canv.config(scrollregion=(0,0,300, 1000)) # canvas size corners canv.config(highlightthickness=0) # no pixels to border sbar = Scrollbar(self) sbar.config(command=canv.yview) # xlink sbar and canv canv.config(yscrollcommand=sbar.set) # move one moves other sbar.pack(side=RIGHT, fill=Y) # pack first=clip last canv.pack(side=LEFT, expand=YES, fill=BOTH) # canv clipped first for i in range(10): canv.create_text(150, 50+(i*100), text='spam'+str(i), fill='beige') canv.bind('<Double-1>', self.onDoubleClick) # set event handler self.canvas = canv def onDoubleClick(self, event): print event.x, event.y print self.canvas.canvasx(event.x), self.canvas.canvasy(event.y) if __name__ == '__main__': ScrolledCanvas().mainloop() This script makes the window in Figure 8-22. It is similar to prior scroll examples, but scrolled canvases introduce two kinks:
Figure 8-22. scrolledcanvas liveSizes are given as configuration options. To specify a view area size, use canvas width and height options. To specify an overall canvas size, give the (X,Y) coordinates of the upper-left and lower-right corners of the canvas in a four-item tuple passed to the scrollregion option. If no view area size is given, a default size is used. If no scrollregion is given, it defaults to the view area size; this makes the scrollbar useless, since the view is assumed to hold the entire canvas. Mapping coordinates is a bit more subtle. If the scrollable view area associated with a canvas is smaller than the canvas at large, then the (X,Y) coordinates returned in event objects are view area coordinates, not overall canvas coordinates. You'll generally want to scale the event coordinates to canvas coordinates, by passing them to the canvasx and canvasy canvas methods before using them to process objects. For example, if you run the scrolled canvas script and watch the messages printed on mouse double-clicks, you'll notice that the event coordinates are always relative to the displayed view window, not the overall canvas: C:\...\PP2E\Gui\Tour>python scrolledcanvas.py 2 0 event x,y when scrolled to top of canvas 2.0 0.0 canvas x,y -same, as long as no border pixels 150 106 150.0 106.0 299 197 299.0 197.0 3 2 event x,y when scrolled to bottom of canvas 3.0 802.0 canvas x,y -y differs radically 296 192 296.0 992.0 152 97 when scrolled to a mid point in the canvas 152.0 599.0 16 187 16.0 689.0 Here, the mapped canvas X is always the same as the canvas X because the display area and canvas are both set at 300 pixels wide (it would be off by two pixels due to automatic borders if not for the script's highlightthickness setting). But notice that the mapped Y is wildly different from the event Y if you click after a vertical scroll. Without scaling, the event's Y incorrectly points to a spot much higher in the canvas. Most of this book's canvas examples need no such scaling -- (0,0) always maps to the upper-left corner of the canvas display in which a mouseclick occurs -- but just because canvases are not scrolled. But see the PyTree program later in this book for an example of a canvas with both horizontal and vertical scrolls, and dynamically changed scroll region sizes. As a rule of thumb, if your canvases scroll, be sure to scale event coordinates to true canvas coordinates in callback handlers that care about positions. Some handlers might not care if events are bound to individual drawn objects instead of the canvas at large; but we need to talk more about events to see why. 8.5.4 Using Canvas EventsLike Text and Listbox, there is no notion of a single command callback for Canvas. Instead, canvas programs generally use other widgets, or the lower-level bind call to set up handlers for mouse-clicks, key-presses, and the like, as in Example 8-14. Example 8-15 shows how to bind events for the canvas itself, in order to implement a few of the more common canvas drawing operations. Example 8-15. PP2E\Gui\Tour\canvasDraw.py################################################################# # draw elastic shapes on a canvas on drag, move on right click; # see canvasDraw_tags*.py for extensions with tags and animation ################################################################# from Tkinter import * trace = 0 class CanvasEventsDemo: def __init__(self, parent=None): canvas = Canvas(width=300, height=300, bg='beige') canvas.pack() canvas.bind('<ButtonPress-1>', self.onStart) # click canvas.bind('<B1-Motion>', self.onGrow) # and drag canvas.bind('<Double-1>', self.onClear) # delete all canvas.bind('<ButtonPress-3>', self.onMove) # move latest self.canvas = canvas self.drawn = None self.kinds = [canvas.create_oval, canvas.create_rectangle] def onStart(self, event): self.shape = self.kinds[0] self.kinds = self.kinds[1:] + self.kinds[:1] # start dragout self.start = event self.drawn = None def onGrow(self, event): # delete and redraw canvas = event.widget if self.drawn: canvas.delete(self.drawn) objectId = self.shape(self.start.x, self.start.y, event.x, event.y) if trace: print objectId self.drawn = objectId def onClear(self, event): event.widget.delete('all') # use tag all def onMove(self, event): if self.drawn: # move to click spot if trace: print self.drawn canvas = event.widget diffX, diffY = (event.x - self.start.x), (event.y - self.start.y) canvas.move(self.drawn, diffX, diffY) self.start = event if __name__ == '__main__': CanvasEventsDemo() mainloop() This script intercepts and processes three mouse-controlled actions:
The net result creates a window like that shown in Figure 8-23 after user interaction. As you drag out objects, the script alternates between ovals and rectangles; set the script's trace global to watch object identifiers scroll on stdout as new objects are drawn during a drag. This screen shot was taken after a few object drag-outs and moves, but you'd never tell from looking at it; run this example on your own computer to get a better feel for the operations it supports. Figure 8-23. canvasDraw after a few drags and moves<IP_ADDRESS> Binding events on specific itemsMuch like we did for the Text widget, it is also possible to bind events for one or more specific objects drawn on a Canvas with its tag_bind method. This call accepts either a tag name string or object ID in its first argument. For instance, you can register a different callback handler for mouseclicks on every drawn item, or on any in a group of drawn and tagged items, rather than for the entire canvas at large. Example 8-16 binds a double-click handler in both the canvas itself and on two specific text items within it, to illustrate the interfaces; it generates Figure 8-24 when run. Example 8-16. PP2E\Gui\Tour\canvas-bind.pyfrom Tkinter import * def onCanvasClick(event): print 'Got canvas click', event.x, event.y, event.widget def onObjectClick(event): print 'Got object click', event.x, event.y, event.widget, print event.widget.find_closest(event.x, event.y) # find text object's id root = Tk() canv = Canvas(root, width=100, height=100) obj1 = canv.create_text(50, 30, text='Click me one') obj2 = canv.create_text(50, 70, text='Click me two') canv.bind('<Double-1>', onCanvasClick) # bind to whole canvas canv.tag_bind(obj1, '<Double-1>', onObjectClick) # bind to drawn item canv.tag_bind(obj2, '<Double-1>', onObjectClick) # a tag works here too canv.pack() root.mainloop() Figure 8-24. Canvas-bind windowObject IDs are passed to tag_bind here, but a tag name string would work too. When you click outside the text items in this script's window, the canvas event handler fires; when either text item is clicked, both the canvas and text object handlers fire. Here is the stdout result after clicking on the canvas twice and on each text item once; the script uses the canvas find_closest method to fetch the object ID of the particular text item clicked (the one closest to the click spot): C:\...\PP2E\Gui\Tour>python canvas-bind.py Got canvas click 3 6 .8217952 canvas clicks Got canvas click 46 52 .8217952 Got object click 51 33 .8217952 (1,) first text click Got canvas click 51 33 .8217952 Got object click 55 69 .8217952 (2,) second text click Got canvas click 55 69 .8217952 We'll revisit the notion of events bound to canvases in the PyDraw example in Chapter 9, where we'll use them to implement a feature-rich paint and motion program. We'll also return to the canvasDraw script later in this chapter, to add tag-based moves and simple animation with time-based tools, so keep this page bookmarked for reference. First, though, let's follow a promising side road to explore another way to lay out widgets within windows. |

Software

The s6-svunlink program
s6-svunlink unlinks a service
directory from a scan directory, then
notifies s6-svscan that a service has
been unregistered. It waits until the s6-supervise
supervisor process managing the service has disappeared, then exits.
The point of s6-svunlink is to help integrate
service directories into an existing service manager sequence and
eliminate race conditions.
Interface
s6-svunlink [ -X ] [ -t timeout ] scandir name
- s6-svunlink expects a running s6-svscan
process on scandir and a fully functional supervised service on
service directory in scandir/name,
which must be a symbolic link to a real directory located somewhere else.
- It deletes the scandir/name symlink.
- It sends a command to s6-svscan to signal it
that a service has disappeared.
- It waits for the s6-supervise process
managing the service directory to exit.
- It exits 0.
Exit codes
- 0: success
- 100: wrong usage
- 111: system call failed
Options
- -X : don't wait. s6-svunlink will exit right
away, without waiting for the supervisor to exit first.
- -t timeout : if the supervisor has not exited
after timeout milliseconds, s6-svunlink will still exit.
The default is 0, meaning no time limit.
Notes
- Using s6-svunlink to stop services is a suboptimal pattern:
starting and stopping supervisors is a heavier operation than just stopping
services. The simpler, more efficient pattern is to simply perform
s6-svc -dwD scandir/name,
which only commands, and waits for, the death of the service, without
impacting the supervisor. Nevertheless, for symmetry with
s6-svlink, this program is provided.
- s6-svunlink is a destructor; as is, it returns 0 even in
situations that are nominal failures. For instance, it returns 0 even
if its timeout expires; the rationale is that there is no sensible action
for the user to do if this error is reported. s6-svunlink only
reports errors when they uncover a deeper problem in the system.
- s6-svunlink sends an s6-svscanctl -an
command to scandir, which means that the system's view of services
will be refreshed and inactive services will be killed and unsupervised.
Depending on what links exist in scandir, new
services may appear, and other services than name may disappear.

This page repeats a sequence of upload and download tests at
intervals, and reports a summary of the entire sequence of tests.
Repeated tests may be able to expose intermittently low speeds.
If only a single test is required, the
NCF Speedtest
will give a more informative (and somewhat more accurate) report.
For the most accurate test results:
This page should be the only open page in your browser.
There should be no other activity on your internet connection,
because the estimated internet speed is based only on the data
received by this page.
The test should run in a device that is connected by ethernet
cable, rather than by Wi-Fi, because interference from other
Wi-Fi access points can reduce your wireless speed to less
than the speed of your internet connection.

Notes
"Not recommended" choices are intended for testing in special circumstances.
The number of bits transmitted is between 9 and 10 times the number of
bytes because each transmission includes control information with the data.
Changing the interval changes the time of the next test. Clicking the button below
