‘Local body elections should be held in fair manner’
by Staff ReporterTHENI
“There’s a lack of transparency on the part of the State government in conducting the local body elections,” said R. Mutharasan, State secretary of Communist Party of India, here on Monday.
A three-day camp was held in Veerapandi near here in which party functionaries from Madurai, Theni and Dindigul districts took part and discussions were held on contesting in the local body polls.
“The sudden shunting of Election Commissioner and transfers of district election-officers raise eyebrows about the intentions of the ruling party. The election should be conducted in a fair and democratic manner,” he said.
He added that the five newly carved-out districts should be properly divided into taluks and wards for the local body elections to take place in a proper manner.
“The lack of local administrative bodies had led to rampant corruption and swindling of public money. Lots of grassroots level problems have not been addressed,” he said.

As a comparative study, I am porting a Red-Black Tree from C++ to the D programming language (Part 1, Part 2). Overall D is an easy, practical transition for the C++ programmer. D provides a number of features for implementing correct code, however it is D’s simplicity that makes it truly enticing as a replacement. While D retains _C Style Syntax, _it is considerably simpler than C++, especially in the presence of exceptions.
Simple and Familiar
Readable code makes maintaining programs simpler, ergo cheaper. D’s syntax stems from the same tree as C, allowing programmers to leverage their considerable experience; yet D comes with a number of useful changes to make code more readable, creating a simple, familiar environment. This project was intended to expose the differences between D and C++. Properties are an excellent example of a small change made in D, which reaps great benefit for readability. Wait, what’s the problem? One can declare getters and setters in C++, isn’t that enough? I say no. Take the following example in C++:
void RedBlackTree::Transplant(RedBlackNode::Ptr u, RedBlackNode::Ptr v)
{
if(u->Parent() == nil)
root = v;
else if(u == u->Parent()->Left())
u->Parent()->Left(v);
else
u->Parent()->Right(v);
v->Parent(u->Parent());
}
Line 6 actually modified u’s right sibling (u->Parent()->Right()). Where is the equal sign? There isn’t one. Experienced C++ programmers are used to looking at this deficiency as status quo. However, its much easier in D to see the statement’s intent.
void Transplant(RedBlackNode u, RedBlackNode v)
{
if(u.Parent == nil)
root = v;
else if(u == v.Parent.Left)
u.Parent.Left = v;
else
u.Parent.Right = v;
v.Parent = u.Parent;
}
D uses the property idiom to clearly show that an assignment is taking place. This simple example is powerful. Notice that the syntax is nearly identical between the 2 languages. This similarity makes it very easy for one to use their current C++ skills almost immediately.
C++ is Whitespace Sensitive
One of the biggest complaints I hear from new python programmers is whitespace sensitivity. Python uses whitespace as a method to control scope, something most editors do automatically anyway using indention.
def fn1(x):
if(x is int):
return 1+1;
else:
x = str(int(x) + 1)
return x;
By forcing whitespace in the syntax braces (“{“ and “}”) are unnecessary, and all python programs look the same making it easier to share code. It works well, and Python if very consistent in it’s implementation. C style languages are not whitespace sensitive, except special cases in C++.
void fn1()
{
vector<vector<int>> stl_2d_vector; //Doesn't compile
vector<vector<int> > stl_2d_vector; //Does compile
}
C++ uses the angle-brackets “<” and “>” for a number of functions:
-
Templates
-
Less-Than, Greater-Than comparison
-
Bit-Wise Shifting
-
Stream-Insertion Operator
-
Stream-Extraction Operator
This isn’t so bad except that there are two separate, semantic classes here. Sometimes the < and > characters are used to enclose text as in the example above. Otherwise, the < and > characters do not enclose text and form an independent operator. Said another way, angle brackets can form a digraph operator, and can form a semantic grouping…depending on the context. Context makes C++ difficult to read.
This is just one example of how the obtuse syntax of C++ makes writing a compiler as well as readable code, difficult. In this example, the compiler is trying to treat the “»” digraph as an operator, instead of grouping the template arguments. The space between the 2 “>” symbol allows the compiler to pair the angle brackets, enclose the template and compile the expression.
D provides a consistent alternative. Which leverage an existing operator for enclosing symbols, the parentheses. D makes instantiating templates easy:
void fn1()
{
vector!(vector!(int)) stl_2d_vector; //Does compile
vector!(vector!(int) ) stl_2d_vector; //Still compiles
}
The “!” operator is always used as a unary operator. Sometimes it can be used as not or one’s complement (bit-twiddle) as in:
if( t != 1) //If T is not equal to 1
//Do Something
t = !t; // One's complement t;
However, ! always means “I stand alone, and I modify the token to my right”. When we create a template, the ! modifies the enclosing parenthetical statement to transform it to a template expression. D does not overload operators, or tokens. D does not use context sensitive syntax. D, like python, allows one to write very readable software.
D gives us tools to write correct code, and offers a simplified syntax that leverages our existing C++ experience. Starting new projects in a new language is a daunting task, yet D offers a lower-risk path in upgrading to a modern language. D isn’t perfect but it provides a number of features for C++ developers to start solving real problems, today.

The Super Bowl is the biggest sporting event of the year in the US, and the sports books offer an outrageous number of wagers you can make. They include important things like who will win and less important things like what will be the first letter in the name of the MVP of The Puppy Bowl. Each one is called a "prop".
Since these details are of crucial importance, I organize a contest every year to see who can correctly predict the most of them. I weight each outcome based on its likelihood -- according to the odds from the sportsbook.
Prizes are not necessary for a contest of this magnitude.

Chris Kamara claims VAR official "decided they didn't want Liverpool to score"
Liverpool were denied an equalising goal at Aston Villa on Saturday, but went on to win the match 2-1
by Mark Jones, https://www.mirror.co.uk/authors/mark-jones/Sky Sports pundit Chris Kamara has hit out at the VAR decision that denied Liverpool a goal at Aston Villa on Saturday, claiming that the call was deliberately made.
With the Reds trailing 1-0 at Villa Park, Roberto Firmino turned home a Sadio Mane cross to equalise in the first half.
The goal was disallowed on the pitch at the time, but a VAR review showed Firmino to be as good as level with Villa defender Tyrone Mings from Mane's cross.
Indeed, as highlighted by Andy Gray on beIN Sports , Firmino was first shown to be onside before the VAR lines were redrawn and he was marginally off.
The decision ultimately didn't matter too much for Liverpool after they came back to win 2-1 thanks to late goals from Andy Robertson and Mane, but Kamara slammed the VAR officials responsible, with the game being overseen by Martin Atkinson.
“I’m not happy with it, I’ll be 100 per cent honest with you," he said on Sky Sports' Goals on Sunday.

“From the naked eye you don’t need that calibration of dots or whatever to tell you, look at Tyrone Mings’ knee, Firmino is onside, right.
 So they’ve done that there - that tells you that he was onside.
“So they change it round now to make it that Firmino is the black line and Tyrone Mings is the yellow line, as you can see now.”
Kamara even held up a piece of paper to the screen to prove that the VAR lines drawn weren't straight.
“But the line that comes up towards Firmino isn’t straight - that’s not a straight line, that’s an angled line," he continued.
“I put a piece of paper to it this morning haven’t I and I showed you - that is not a straight line.
“Get your rulers out, get your spirit level out. That red line is not a straight line.
“Now, somebody has decided to do that and I think they should be outed because that is not offside for me.
“That’s why it’s not a straight line, look at that paper, look how angled it is, that’s not a straight line.”
Liverpool's late win keeps them six points clear at the top of the Premier League table ahead of a meeting with second-place Manchester City next Sunday.

./manage.py flickr_sync [options]
-u USER_ID, --user=USER_ID
Sync for a particular user. Default is 1 (in most
cases it's the admin and you're using it only for
yourself).
-i, --info Fetch info for photos. It will take a long time to
sync as it needs to fetch Flickr data for every photo
separately.
-e, --exif Fetch exif for photos. It will take a long time to
sync as it needs to fetch Flickr data for every photo
separately.
-s, --sizes Fetch sizes details for photos. It is not needed,
sizes can be obtained dynanmically. It will take a
long time as it needs to fetch Flickr data for every
photo separately.
-g, --geo Fetch geo data for photos. It will take a long time as
it needs to fetch Flickr data for every photo
separately.
-p, --photosets Sync photosets. Photos must be synced first. If photo
from photoset not in our db, it will be ommited.
-c, --collections Sync collections. Photos and sets must be synced
first.
--no-photos Don't sync photos.
-d DAYS, --days=DAYS Sync photos from the last n days.
--page=PAGE Grab a specific portion of photos. To be used with
--per_page.
--per-page=PER_PAGE How many photos per page should we grab? Set low value
(10-50) for daily/weekly updates so there is less to
parse, set high value (200-500) for initial sync and
big updates so we hit flickr less.
--ils Ignore last_sync.
--initial It assumpts db flickr tables are empty and blindly
hits create().
-t, --test Test/simulate. Don't write results to db.
./manage.py flickr_download [options]
-u USER_ID, --user=USER_ID
Sync for a particular user. Default is 1 (in most
cases it's the admin and you're using it only for
yourself).
-a, --all By default downloads only photos which have not been
downloaded (default behavior). Use this option to
(re)download all.
-p, --public Only public photos.
-s, --size Specify size for download (by default original for pro
accounts and large for non-pro).
-r, --reset Clear downloads db table. Does not affect your files.
Photos are downloaded under your MEDIA folder. Default settings you can override:
# default settings
FLICKR_DOWNLOAD_DIRBASE = 'flickr' # under MEDIA_ROOT
FLICKR_DOWNLOAD_DIRFORMAT = '%Y/%Y-%m' # Photo.date_posted
# photos with date_posted January 2009 will land in /media/flickr/2009/2009-01/
# example custom settings
FLICKR_DOWNLOAD_DIRBASE = 'downloads'
FLICKR_DOWNLOAD_DIRFORMAT = '%Y/%m/%d'
# photos with date_posted 23 January 2009 will land in /media/downloads/2009/01/23/ etc.

Bootbox.js
Bootstrap modals made easy.
Bootstrap modals made easy.
Bootbox.js is a small JavaScript library which allows you to create programmatic dialog boxes using Bootstrap modals, without having to worry about creating, managing or removing any of the required DOM elements or JS event handlers. Here’s the simplest possible example:
bootbox.alert("Hello world!");
Compare that to the code you’d have to write without Bootbox:
Bootbox is proudly sponsored by Finch. Test local websites across multiple devices, share them with your team and get feedback from clients through a secure, public URL.The library exposes three methods designed to mimic their native JavaScript equivalents. Their exact method signatures are flexible as each can take various parameters to customise labels and specify defaults, but they are most commonly called like so:
The only required argument for alert calls is message; callback is required for confirm and prompt calls in order to determine what the user’s response was. Even when calling alert a callback is useful to determine when the user dismissed the dialog since our wrapper methods can’t & don’t block like their native counterparts: they are asynchronous rather than synchronous.
Each of these three methods calls a fourth public method which you too can use to create your own custom dialogs:
Please note: the ‘Example’ object used in the following examples simply displays a notification to help illustrate when each callback is invoked. It is nothing to do with Bootbox itself, but you may view its source if you’re interested in how it works.
The latest stable version of Bootbox is 4.4.0. You can download the minified library bootbox.min.js for use in production, or the uncompressed bootbox.js for use in development. I wouldn’t recommend hotlinking to either file as Github does not serve the correct mime type which may cause security warnings to be triggered based on your browser’s settings.
If you wish you may also see a full list of releases or download the latest copy of the entire repository (including build files and tests) in zip or tarball format. Realistically the only reason you should be using anything other than the 4.x.x series is if you are restricted by the version of Bootstrap you’re using—see the following section for full details.
Bootbox is also available as an npm package and can be installed in the usual way:
npm install bootbox
All versions of Bootbox stand on the shoulders of two great giants: Bootstrap and jQuery. The exact version of Bootstrap depends on the version of Bootbox you’re using. This has become slightly more complex than I’d like but hopefully this handy table will clear things up (if it doesn’t then please tell me!):
| Bootbox version | Min. Bootstrap version | Max. Bootstrap | Min. jQuery | Notes |
|---|---|---|---|---|
| 4.x.x Latest | 3.0.0 | 3.0.0 | 1.9.1 | Current release. Entirely rewritten to support Bootstrap 3.0.0 |
| 3.x.x | 2.2.2 | 2.3.2 | 1.8.3 | Last version to support Bootstrap 2 |
| 2.x.x | 2.0.0 | 2.0.4 | 1.7.1 | As you can see, Bootstrap 2.1.x was never officially supported |
| 1.x.x | 1.3.0 | 1.4.0 | 1.7.1 | Don’t download this version of Bootbox—it’s old |
Once you’ve got your dependencies sorted, usage is fairly straightforward and much like any other JavaScript library you’ve ever used. The library creates a single global instance of a bootbox object:
Bootbox was originally created in 2011 with the sole purpose of wrapping JavaScript’s low level dialog methods with Bootstrap’s high level modal functionality. As such it is a small library focussed on providing basic programmatic dialogs with minimal fuss and overhead.
Bootbox is authored and maintained by Nick Payne (@makeusabrew). Thanks are also due to the contributors!
When you’re up and running check out some examples or the documentation.
Bootbox is a free, open source project. As such you can help out in a number of ways from simply raising an issue to forking the project and submitting a pull request.
I’m particularly keen to improve the examples and make a proper start on the API docs, so pull requests contributing towards the gh-pages branch (which you’re looking at!) are extremely welcome.
Lastly—please just help spread the word!


Ruby is a programming language focused on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. The Ruby programming language is most commonly used with the Ruby on Rails framework.
Ruby and Rails are typically used by younger companies and startups, especially for building interactive web applications. Companies using Ruby and Rails who have hired Epicodus graduates include New Relic, LivingSocial, and SpendWell.
After establishing solid programming fundamentals in the Introduction to Programming course, this course introduces students to the Ruby framework and gives them more difficult problems to solve and a more advanced set of tools to solve them with. It also establishes the foundations for learning real-world technologies used by programmers on the job. The outline of topics for this course is as follows:
Ruby on Rails programming is crucial for aspiring programmers seeking a career in Ruby on Rails web development.
PHP is a popular programming language used for web development, especially for content-heavy websites. It's most commonly used with content management systems like WordPress, Drupal, and Joomla, but is also used in many web applications and backends as well. Students who learn to code in PHP will be able to collect form data, generate dynamic page content, send and receive cookies, and much more.
Intel, Metal Toad, and OpenSesame are all companies that use PHP and have hired Epicodus graduates in the past.
The PHP course builds on the programming fundamentals from our Introduction to Programming course and gives students more difficult problems to solve, a more advanced set of tools to solve them with, and establishes the foundations for learning the real-world technologies used by programmers on the job. Students will have the opportunity to learn PHP programming and build content-focused websites as well as get acquainted with database systems through SQL programming. The outline of topics for this course is as follows:
Learning how to code in PHP is vital for aspiring programmers as it is fundamental in the field of web and mobile development.
Java is arguably the most popular programming language today. It's used for everything from web applications to backend services to mobile applications to embedded systems. Students who learn Java programming will be able to create dynamic web applications, and be able continue into our Android track.
Companies using Java who have hired Epicodus graduates include Nike and Thetus.

It establishes the foundations for learning the real-world technologies used by programmers on the job.
Through this Java course, students will learn how to code in Java —one of the most widely-used programming languages, used in everything from Android apps to large enterprise development.
CSS is the language for describing the presentation of Web pages, including colors, layout, fonts, and other stylistic choices. It allows one to adapt the presentation to different types of devices, such as large screens, small screens, and printers. HTML — used for building the structure of the page — and CSS — used for the visual layout — are the two basic languages involved in the building of web pages and web applications.
This CSS course building on the fundamentals from our Introduction to Programming Course. Students who learn CSS will be able to style web pages using complex, responsive layouts, while gaining exposure to the latest CSS tools, tricks, and features used every day by front-end developers and designers.
CSS programming is an integral part of front-end development. CSS – along with HTML and JavaScript – helps front-end developers control what the user of a website can see and do.
The C# ("C sharp") programming language is most commonly used with the .NET framework. Students who are well-versed in C# programming can use it to create client applications, database applications, distributed components, and much more.
Students who learn C# programming and combine it with their knowledge of the .NET framework can target larger enterprises, government agencies, and companies serving enterprise and government clients for employment.

Uses logical elimination techniques to solve sudoku puzzles. This implemenation is written using AngularJS and Ajax calls with a python implementation in order to display it on the
web. This by far one of my favorite projects I have worked on and have implemented my solving algorithm in python and jave, with a GUI in each (Applet based in java) and callable functionality in python. There is also a Java Applet version I made. There are also versions I have written in Python as a
command line application and also as a
GUI '.app' version.

Barriers, Robert Hamilton, Google
Why we need to be open in the way we design and do things. People think mobile is open. (asks how many people have SIM cards).
If mobile was created by Internet folks, there'd be no SIM card - you'd just login from anywhere, on multiple devices, like on the web.
SIM is supposedly great for identity, but is that really necessary for security purposes, given what most people buy using username and password over iTunes, Amazon, etc?
(Shows picture of a ticket gate in Japan)
There's no barrier here. It only closes when someone tries to get in without a ticket - it presumes innocence. This saves electricity, wear and tear, and avoids penalising people who aren't doing anything wrong.
Japanese built a transport network to move people, not to create queues. Don't hinder people who are trying to use your service correctly.
 That's fine. Drop £10 in a bar. You'll usually be given it back. This is the world we live in, and it's the world we create.
Put barriers in the way and you force out a different sort of product. Twitter didn't consider "people might want to make Tower Bridge tweet" - they're just open, and people use them in interesting new ways.
"Build a climbing frame, not a cage" - it's the same structure, just a different mental model of what you do with it.
Look at app stores: some people pick winners (e.g. Apple). The web wasn't built this way. Another example: network operators wanted to charge 10c per lookup. People didn't want to pay, so it sat there. Google decided this was fundamentally useful to users and have released a location API, Google Gears, WebKit, etc.
Our philosophy: build things people want to use. Google Wave is a bit weird - we want other people to come onto this.
Q: Where does Gears for Mobile fit?
A: We're more about standards in the browser than getting Gears out there. We're now getting geolocation APIs in W3C standards. Gears got us in there, but has done its job now.
Q: How do you see widgets fitting into the web?
A: Define widgets. The Palm Pre is all widgets - the dialler is written in Javascript. Widgets have a place because users don't think about using a browser. Showing things in a browser isn't the end use case of everything. They let users build their own climbing frame, rather than going to a full web experience. Widget platforms will become browsers.
Q: Should I be worried that all my passwords are the same?
A: SIM is solving a problem that doesn't exist.
Q: Why not do away with passwords?
A: You still have to authenticate. You have to have reasonable barriers for privacy and reputation. Larry says "the internet is too anonymous". If you can authenticate more easily then this might be addressable. The SIM is not the answer.
Q: Should I have to login to execute a google search? Even creating a username is an intolerable overhead.
A: No.
Q: I agree with the philosophy of open. It's great for users, but lots of businesses aren't making money from it. So what's the future of it?
A: It's a truism that people will pay for good things. We don't have micropayments. It's hard to do things at that level. We had 10c payments with AOL but got rid of it. It's easy to do it with a good product. Small app developers will do well. There were lots of mom'n'pop shop writing Newton apps and doing quite well. If you don't have to do distribution, you can make a living selling things for $5.
Symbian? What's that? Barbara Ballard
Nokia has 6% penetration in the US, maybe lower.
60% of US subscribers now text, but email a lot via Blackberry - because we like email. But we do more mobile web than European. In the 90s we stayed online all day using dialup, so email was always available... but not 2-way SMS or operator interop.
RIM put together an ecosystem for email as sophisticated as Apple's for music: consumption, servers, Exchange integration, fast setup, works well on 2G. Some US people call any candybar phone with a keyboard a Blackberry.
By comparison, it takes 77 clicks to set up email for Nokia.
Until recently BB had no Javascript, CSS or stylesheets activated.
30% of US iphone users were carrying a second device last year, frequently RAZRs (still). The whole federal government carry BBs. So our mobile web world is Blackberry, iPhone, RAZR...
So, Internet vs Telco: a framework for understanding company behaviours. Not here to slag operators, most problems are a result of silo thinking.
When SV and Bay area companies approach Little Springs, they want iPhone stuff. It used to be they wanted to run anywhere. Nowadays, if it's not Android/Palm/iPhone it's irrelevant. But Internet thinking like this misses 96% of other devices.
Telco thinking: Sprint is not a bad telco from a UX experience, hiring UX since 2007. AT&T hired their first one in 2007!
Telcos tend towards device-specific design... which made it expensive to get content providers involved. They're big on customisation and feature phones.  Content providers have to support everything, though, back to 4 years ago.
Hybrid thinking, now: thematic consistency. Not the same web everywhere; tweak slightly for devices. Avoid accesskeys on QWERTY phones. Add padding around buttons for touch devices. Dynamic number of results (5 on RAZR, more on others).
One or more versions (of page, sub-site, or site). Graceful degradation. Page "tweaks".
Q: How's Android affecting the US market?
A: It's on the 4th largest operator. We're expecting to see more.
Q: What about device APIs for things like WRT or Qt?
A: I'm anxiously awaiting data in large enough volumes for me to play with it.
Q: What about applications?
A: If the dev teams are silo'd, I give them separate specs. If they're more sophisticated, I use this approach. With J2ME Polish they can do 1 build a day (seems slow - Ed.).
Gestural Interactions, Younghee Jung & Joe Macleod
Joe: air-kissing is a headfuck.
YJ: We don't remember our first encounter with human beings, but we do remember our first interactions with computers. How do we interact with technology more naturally.
(shows photo of electronic cats)
YJ: Technology is poor at mimicking natural expressions. Verbal communication is only a fraction of how we talk.
JMcL: We fight over videoconferencing suites at work. We have good ones, but they're no better than iChat.
YJ: I pick up new body language easily.
JMcL: The gesture of fingers on lips travels well...
JY: ...but some are very specific.
(I had difficulty taking useful notes of what was an excellent presentation containing oodles of gestures).
Modelling the mobile experience, Bryan Rieger
Started out doing lots of animation, motion graphics. Worked with Buxton. Getting into Processing more recently.
"My journey playing cognitive connect the dots through a road in hell"
Wireframes are "layout, behaviour and flow" - that's a lot of stuff to be putting in a document.
Let's just deal with flow... you've written a wireframe for a screen. What happens next - you imagine what happens and your mind interprets, filling in the blanks.
What happens between the "frames" in wireframes?
Clients require more detail... too much detail.
End up in UML. Bryan shows a standard UML diagram for a light bulb. Standards require literacy. Now we're shipping huge wireframes and literary references... which are hard to manage, get less feedback, are never updated, are hard to change...
So it's too much. So we build a prototype.
Paper is lovely but limited. Requires interpretation, is hard to share. This leaves us with HTML/Flash/Python/Java - requiring programming. HTML works well for web projects tho.
Prototypes are challenging - need development resources, get hijacked by development, fail to find right level of abstraction, unwillingness to iterate from dev team, and suddenly: development is happening in design.
Iterations are opportunities for design. But what's the software equivalent of the cutting room floor?
Demos beautiful little modelling tool.
(Thoughts: is it an issue of trust? wireframes are a tool for communication. within a team, face to face communication is high bandwidth, warm, works well. if a small team can work together and do it... we're ok. Problems come when we need to communicate or validate outside the team. In particular i've seen this when you're haing a client sign off... or when QA is involved to validate your work (whether external or internal))

Your endowment:
At the beginning of every round,
you will be assigned X coins.
Your contribution:
Each round, you will have to choose how many coins to put directly into
your personal account, and how many coins to put into a group account.
Return from personal account:
Each coin that you put into your personal account goes one-to-one towards your payoff.
Return from the group account:
Every group member receives half of the total amount of coins in the group account.
Payoff:
Your payoff will be equal to: Your Endowment - Your Contribution + Return from the group account.
Total return:
You will be paid the sum of all your payoffs.


How it works
For BabelSheet to know how to handle your translations, you need to stick with very simple spreadsheet markup.
Metadata:
###
- determines column with optional tags, each tag describes whole row, there might be more tags per row and they should be separated by a comma>>>
- determines column with translation key, there might be more such columns placed one after another, each column makes another key which is nested, e.g.CORE.LABELS
orFRONT.HEADER.TITLE
.- locale, e.g.
en_US
,pl_PL
and others - determines column with translations for specific locale
Example:
| ### | >>> | >>> | >>> | en | pl |
|---|---|---|---|---|---|
| CORE | |||||
| LABELS | |||||
| tag1, tag2 | YES | Yes | Tak | ||
| tag1 | NO | No | Nie | ||
| FRONT | |||||
| HEADER | |||||
| TITLE | Something | Coś |
Nothing is more self-explanatory then a working example.


Build system
XLS uses the Bazel build system for itself and all its dependencies. Bazel is an easy to configure and use, and has powerful extension facilities. (It's also well-documented!) XLS provdes a number of Starlark macros, described below, to simplify build target definition.
Macros
Below are summaries of public macro functionality. Full documentation is available in xls/build_rules/build_defs.bzl.
dslx_codegen
This macro generates Verilog from an DSLX target (currently given as a
dslx_test
target). This target also accepts several key/value parameters (as
configs
for generation):
clock_period_ps
: The target clock period in picoseconds. Only used with the pipeline generator.clock_margin_percent
: The percent of the target clock period to reserve as "margin". Only used with the pipeline generator.entry
: The DSLX function to synthesize. If not given, a "best guess" will be made.flop_inputs
,flop_outputs
: Whether to add flops at the inputs/outputs of the generated module. Only used with the pipeline generator.generator
: The code generator to be used. Can be eithercombinational
orpipeline
.module_name
: The desired name of the generated Verilog module.pipeline_stages
: The desired number of pipeline stages.reset
: The name of the reset signal to use, if any.reset_active_low
: Whether the reset signal is active low. Must also specifyreset
option. Only used with the pipeline generator.
dslx_jit_wrapper
Generates a source/header file pair to wrap invocation of a DSLX function by the JIT - this wrapper is a much more straightforward way to interact with the JIT versus direct use. It accepts a DSLX target and entry function in the same manner as above.
dslx_test
Main driver for:
- Compiling DSLX files to IR
- Running DSLX test cases (defined alongside the designs)
- Proving DSLX/IR equivalence
- Generating a benchmark for the associated IR
- Proving logical equivalence for the optimized vs. unoptimized IR
In general, if one has a DSLX .x file, there should be an associated dslx_test
target - this is the entry point to "downstream" capabilities (IR
transformations, codegen, interpretation/JIT, etc.).
The "entry" attribute to the dslx_test
rule, if provided, must be an IR symbol
(which is a "mangled" DSLX name). Prefer to use the dslx_mangle
macro to
construct these mangled names from BUILD
files.
Note: This macro is targeted for refactoring, as it currently contains a broad swath of not-always-directly-related functionality.
dslx_generated_rtl
This macro is for internal developer use only, for generating RTL with internally-released toolchains.
Bazel queries
Understanding the build tree for a new project can be difficult, but fortunately
Bazel provides a
powerful query mechanism.
bazel query
enables a user to examine build targets, dependencies between
them, and much more. A few usage examples are provided here, but the full
documentation (linked above) is comprehensive.
Finding transitive dependencies
To understand why, for example, the combinational verilog generator depends on the ABSL container algorithm library, one could run:
$ bazel query 'somepath(//xls/codegen:combinational_generator, @com_google_absl//absl/algorithm:container)'
//xls/codegen:combinational_generator
//xls/codegen:vast
@com_google_absl//absl/algorithm:container
This result shows that one such path goes through the :vast
target. Another
such path goes through the xls/ir:ir target, then the xls/ir:value target.
somepath
provides some path, not all paths (that's what allpaths
is for).
Finding dependees ("reverse dependencies")
Sometimes it's useful to identify the set of targets depending on some other
target - the rdeps
query performs this:
$ bazel query 'rdeps(//xls/codegen:all, //xls/codegen:combinational_generator)'
//xls/codegen:flattening_test
//xls/ir:ir_test_base
//xls/codegen:combinational_generator_test
//xls/codegen:combinational_generator
This shows the transitive closure of all dependencies of the combinational
generator, with the starting set being all targets in //xls/codegen:all
. This
set of dependees can quickly grow to be unmanageable, so keep the initial set
(the first argument) as small as possible, and consider specifying a third
argument for maximum search depth.

Waze Now Displays Estimated Toll Prices To Your Destination
by Bryan LimWaze has been providing users with navigation routes, which may include tolls for a quicker route. Recently, the app has been updated to display toll prices in Malaysia, allowing users to compare them between routes.
The toll prices display feature is now live for both Android and iOS device. As we checked, the feature does work for most tolls, including the North-South Expressway. However, there are still some tolls that still don’t have prices displayed yet. For example, the Kajang station on the North-South Expressway, from Mid Valley City to KLIA.
That said, Waze utilises community feedback and map editors to bring information to other users. We can most likely be able to see all the tolls fully supported as map editors continue to add toll information into the app.
As for now, drivers can now get an estimation of toll charges to their destination to prepare credits for their Touch n’ Go card. On the other hand, this feature is not exactly new from Waze as it was first implemented in the US and Canada back in July this year.


Introduction
-
Tasks:
-
Image Segmentation : The process of assigning a label to every pixel in the image.
-
Semantic Segmentation : treats multiple objects of the same class as a single entity.
-
Instance Segmentation : treats multiple objects of the same class as distinct individual objects.
-
1. FCN (2015)
-
Introduction : The first end-to-end pixel-wise prediction model based only on convolutional layers.
-
Method:
- Feature Extraction : using convolution layers like conventional Image Classification Tasks (layer 1,2,3,4,5)
- Convolutionalizing : Downsampling using 1x1 conv rather than FC layer(layer 6,7,8)
- Pixel Wise Classification : Last conv1x1 layer performs pixel wise classification for 21 classes.
- Upsampling : using deconvolution layer, also called transposed convolution
- Fusing Output : x32 upsample from pool5 (FCN-32S) + x16 upsample from pool4 (FCN16S) + x8 upsample from pool3 (FCN8S)
2. Mask R-CNN (2017)
-
Introduction : to detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance.
-
Method : just add a third branch that outputs the object mask.
-
Feature Extraction is same as Faster RCNN
-
RPN is same as Faster RCNN
-
The 3rd tails outputs (class + box offset + a binary mask) for each ROI in parallel.
- 3.1 : Class labels are collapsed into a short output vectors by FC layers, same as Faster RCNN
- 3.2 : Box offset is collapsed into a short output vectors by FV layers, same as Faster faster_RCNN
- 3.3 : $m \times m $ masks are predicted for each ROI using an FCN
-
ROI Align : If we use ROI pool at the above process, there would be small difference between the real ROI and extracted feature map. It does not matter in classification task, but does in segmentation. To address this problem, authors proposed ROI Align.

I18n serves for translating parts of your application to different languages. It uses a message catalogue to look up a message in a given language which is identified by a unique key.
This example assumes that you are using the XMLResource (or any other subclass of BasicXMLResource).
Example message catalogue (let's say it's stored in the default repository of your realm, with the path /i18n/foo.xml):
<?xml version="1.0" encoding="UTF-8" ?>
<messages>
<message key="foo.user">
<text language="de">Benutzer</text>
<text language="en">User</text>
</message>
<message key="foo.logout">
<text language="de">Abmelden</text>
<text language="en">Log out</text>
</message>
<message key="foo.registeredUsers">
<text language="de">Es sind {0} Benutzer registriert.</text>
<text language="en">{0} users are registered.</text>
</message>
</messages>
To translate text using this catalogue, use the following code in your xslt:
<i18n:text xmlns:i18n="http://www.wyona.org/yanel/i18n/1.0" key="foo.user"/>
To translate an attribute:
<input type="submit" value="foo.logout" i18n:attr="value"/>
Or when there are multiple attributes using i18n:
<input type="button" name="Name" value="foo.button.value" title="foo.button.tooltip" i18n:attr="value title"/>
To translate a text with parameters:
<i18n:translate>
<i18n:text key="foo.registeredUsers"/>
<i18n:param>7</i18n:param>
</i18n:translate>
The catalogue has to be associated with the content. There are two ways to do so:
Resource-specific messages
Add a property to the resource configuration file (.yanel-rc):
<i18n-catalogue>yanelrepo:/i18n/foo.xml</i18n-catalogue>
Realm specific messages
Add the following element to your realm.xml:
<i18n-catalogue>yanelrepo:/i18n/foo.xml</i18n-catalogue>
There is a transformer (I18nTransformer) which transforms the <i18n:text> elements into the text messages from the catalogue. If no message is found for a given key and a given language, fallback to the default language is applied. If still no message is found, the transformer inserts the message key.
As of today there are three different versions of this transformer in yanel: I18nTransformer, I18nTransformer2, and I18nTransformer3. The first two versions are deprecated. They use a different syntax and they support only plain-text property files as catalogues (ResourceBundles, which means the catalogues are loaded from the classpath).
I18nTransformer3 still supports the old syntax and also allows to use ResourceBundle catalogues, so it's the recommended choice.
It is possible to have more than one catalogue.
A resource configuration can have several catalogues, the realm can have one, and Yanel has a global message catalogue (see WEB-INF/classes/global_en.properties
or WEB-INF/classes/global_de.properties
). Yanel will look for a message with a given key first in the resource catalogues, then in the realm catalogue, and eventually in the global catalogue.
One can also configure a resource specific catalogue. See for example:
src/realms/yanel-website/res-configs-repo/data/en/contact.html.yanel-rcand in particular
<yanel:property name="i18n-catalogue" value="contact-form"/>which is the resource configuration of http://<IP_ADDRESS>:8080/yanel/yanel-website/en/contact.html.
src/resources/contact-form/conf
, which are copied during the
build process to local/TOMCAT/webapps/yanel/WEB-INF/classes
, from where the I18nTransformers will read them.

Apart from being a web developer, I enjoy most of my time being outdoors. In the winter, I am an avid skier and novice ice climber. During the warmer months here in Colorado, I enjoy mountain biking, free climbing, and kayaking.
When forced indoors, I follow a number of sci-fi and fantasy genre movies and television shows, I am an aspiring chef, and I spend a large amount of my free time exploring the latest technology advancements in the front-end web development world.

In February we embarked on a spontaneous Melbourne holiday and Public Transport Extravaganza thanks to CountryLink and my sister who lives there. There may have been elements of City Mouse/Country Mouse, but overall came off okay with no injuries and lots of fond memories.

My name is Jack Kinsey (if you haven't already guessed
that), and I am a programmer, developer, and designer.
I mostly work on web and game related projects, which
you can learn more about here.
Or, if you are looking for my resume, you can get it from
my Dropbox, here.
Anyway, this is the "about" section of this website so
if you are still reading this, then I can only assume
that you'd like to know a little more about me. Very
well. As I mentioned, I am a programmer, which means I
love to solve problems. I am a developer, which means I
love searching for the best solutions to those problems.
And I am a designer, which means I like for those
solutions to look pretty.
Currently, I work for Microsoft as a Service Advisor,
and work on small, side projects in my spare time. If
you would like to contact me, you can find me on Twitter
(@jackwkinsey),
or visit my contact page for
other ways to reach me.


I co-host a semi-regular cubing podcast with Andrew Nathenson called Layer by Layer. Give it a listen, and be sure to discuss the topics with us at our subreddit!


The Search form (from Step 1. Specifying criteria) contains a Load... button (shown circled in red Figure 1).
To access your Search history: click on the Load button. This will launch the Search history form (shown in Figure 2).
To select criteria from any previous search simply: click on the row.
Note: selecting a row is selecting all of the criteria for a future search. Presently, there is no way to select only one criterion.
Note: if you need more space to view: the form itself is resizable and scrollbars are also provided. Additionally, the table headings are also resizable.
When you have finished making a selection, click on the Okay button and the Search history form will close and the Search form you return to will be populated with the criteria of the past search that you selected.
Alternatively, if you would like to cancel: click on the Cancel button and the Search history form will close and the Search form you return to will remain unchanged.
In either case: see Searching, Step 1. Specifying criteria to continue on a search.
By default, the files are sorted in chronological order based on when you search for them. To sort the files based on Type, Pattern, Options, XPath, Filter, and Paths: click on the respective table heading.
To alternate between ascending and descending order: click again on the already selected table heading. This will toggle from ascending to descending or from descending to ascending based on the current state.
