Monitors Java Virtual Machines (JVMs) and enables remote monitoring tools to attach to JVMs. This command is experimental and unsupported.
The jstatd
command is an RMI server application that monitors for the creation and termination of instrumented Java HotSpot VMs and provides an interface to enable remote monitoring tools to attach to JVMs that are running on the local host.
The jstatd
server requires an RMI registry on the local host. The jstatd
server attempts to attach to the RMI registry on the default port, or on the port you specify with the -p
port
option. If an RMI registry is not found, then one is created within the jstatd
application that is bound to the port that is indicated by the -p
port
option or to the default RMI registry port when the -p
port
option is omitted. You can stop the creation of an internal RMI registry by specifying the -nr
option.
Does not attempt to create an internal RMI registry within the jstatd
process when an existing RMI registry is not found.
The port number where the RMI registry is expected to be found, or when not found, created if the -nr
option is not specified.
Name to which the remote RMI object is bound in the RMI registry. The default name is JStatRemoteHost
. If multiple jstatd
servers are started on the same host, then the name of the exported RMI object for each server can be made unique by specifying this option. However, doing so requires that the unique server name be included in the monitoring client's hostid
and vmid
strings.
Passes option
to the JVM, where option is one of the options
described on the reference page for the Java application launcher. For example, -J-Xms48m
sets the startup memory to 48 MB. See java
(1).
The jstatd
server can only monitor JVMs for which it has the appropriate native access permissions. Therefore, the jstatd
process must be running with the same user credentials as the target JVMs. Some user credentials, such as the root user in Solaris, Linux, and OS X operating systems, have permission to access the instrumentation exported by any JVM on the system. A jstatd
process running with such credentials can monitor any JVM on the system, but introduces additional security concerns.
The jstatd
server does not provide any authentication of remote clients. Therefore, running a jstatd
server process exposes the instrumentation export by all JVMs for which the jstatd
process has access permissions to any user on the network. This exposure might be undesirable in your environment, and therefore, local security policies should be considered before you start the jstatd
process, particularly in production environments or on networks that are not secure.
The jstatd
server installs an instance of RMISecurityPolicy
when no other security manager is installed, and therefore, requires a security policy file to be specified. The policy file must conform to Default Policy Implementation and Policy File Syntax at
http://docs.oracle.com/javase/8/docs/technotes/guides/security/PolicyFiles.html
The following policy file allows the jstatd
server to run without any security exceptions. This policy is less liberal than granting all permissions to all code bases, but is more liberal than a policy that grants the minimal permissions to run the jstatd
server.
grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission; };
To use this policy setting, copy the text into a file called jstatd.all.policy
and run the jstatd
server as follows:
jstatd -J-Djava.security.policy=jstatd.all.policy
For sites with more restrictive security practices, it is possible to use a custom policy file to limit access to specific trusted hosts or networks, though such techniques are subject to IP address spoofing attacks. If your security concerns cannot be addressed with a customized policy file, then the safest action is to not run the jstatd
server and use the jstat
and jps
tools locally.
The interface exported by the jstatd
process is proprietary and guaranteed to change. Users and developers are discouraged from writing to this interface.
The following are examples of the jstatd
command. The jstatd
scripts automatically start the server in the background
This example shows how to start a jstatd
session with an internal RMI registry. This example assumes that no other server is bound to the default RMI registry port (port 1099).
jstatd -J-Djava.security.policy=all.policy
This example starts a jstatd
session with a external RMI registry.
rmiregistry& jstatd -J-Djava.security.policy=all.policy
This example starts a jstatd
session with an external RMI registry server on port 2020.
jrmiregistry 2020& jstatd -J-Djava.security.policy=all.policy -p 2020
This example starts a jstatd
session with an external RMI registry on port 2020 that is bound to AlternateJstatdServerName
.
rmiregistry 2020& jstatd -J-Djava.security.policy=all.policy -p 2020 -n AlternateJstatdServerName
This example starts a jstatd
session that does not create an RMI registry when one is not found. This example assumes an RMI registry is already running. If an RMI registry is not running, then an error message is displayed.
jstatd -J-Djava.security.policy=all.policy -nr

Inline vs Inline Block
There are different ways to position content in HTML to make your page look good. Two of these are the CSS properties display:inline and display: inline-block. We are going to examine the differences between these two styles.
Inline
Inline is the default property for some elements such as  and . Inline positioning displays content sequentially without any spaces or line breaks. As the name "inline" implies, it basically keeps things on the same horizantal line.
The image above is actually two HTML paragraphs. Normally there would be a break between the two and they would be stacked vertically, but here because we use display: inline, the second paragraph begins immediately following the end of the first and therefore they appear as one.
display: inline;
background: grey;
}

 Lorem ipsum dolor...

 Lorem ipsum dolor...

Inline-Block
Inline-block is a method of displaying HTML in block on the same horizantal line. Normally display: block displays HTML elements stacked vertically. Display: inline-block stacks them horizantally. It can be used as an alternative to float.
The above image displays the same two paragraphs using display: inline-block. As the name inline-block suggests, the elements are displayed as blocks on the same horizontal line. If they were displayed as regular blocks they would display as vertically stacked.
width: 300px;
display: inline-block;
background: grey;

I remember once seeing a PHP framework advertising support for UTF-8. This struck me as surprising: you mean having UTF-8 support isn’t automatic? In the Haskell world, issues like character encoding are already well addressed and fully supported. In fact, we usually have the opposite problem: there are a number of packages providing powerful and well-designed support for the problem. The Haskell community is constantly pushing the boundaries finding the cleanest, most efficient solutions for each challenge.
The downside of such a powerful ecosystem is the complexity of choice. By using Yesod, you will already have most of the tools chosen for you, and you can be guaranteed they work together. Of course, you always have the option of pulling in your own solution.
As a real-life example, Yesod and Hamlet (the default templating language) use blaze-builder
for textual content generation. This choice was made because blaze provides the fastest interface for generating UTF-8 data. Anyone who wants to use one of the other great libraries out there, such as text
, should have no problem dropping it in.

CSS Grid Layout is the most powerful layout system available in CSS. It is a 2-dimensional system, meaning it can handle both columns and rows, unlike flexbox which is largely a 1-dimensional system. You work with Grid Layout by applying CSS rules both to a parent element (which becomes the Grid Container) and to that element’s children (which become Grid Items).
CSS Grid Layout (aka “Grid”), is a two-dimensional grid-based layout system that aims to do nothing less than completely change the way we design grid-based user interfaces. CSS has always been used to lay out our web pages, but it’s never done a very good job of it. First, we used tables, then floats, positioning and inline-block, but all of these methods were essentially hacks and left out a lot of important functionality (vertical centering, for instance).
Flexbox helped out, but it’s intended for simpler one-dimensional layouts, not complex two-dimensional ones (Flexbox and Grid actually work very well together). Grid is the very first CSS module created specifically to solve the layout problems we’ve all been hacking our way around for as long as we’ve been making websites.
As of March 2017, most browsers shipped native, unprefixed support for CSS Grid: Chrome (including on Android), Firefox, Safari (including on iOS), and Opera. Internet Explorer 10 and 11 on the other hand support it, but it’s an old implementation with an outdated syntax. The time to build with grid is now!
To get started you have to define a container element as a grid with display: grid, set the column and row sizes with grid-template-columns and grid-template-rows, and then place its child elements into the grid with grid-column and grid-row.
This browser support data is from Caniuse , which has more detail. A number indicates that browser supports the feature at that version and up.
Before diving into the concepts of Grid it’s important to understand the terminology. Since the terms involved here are all kinda conceptually similar, it’s easy to confuse them with one another if you don’t first memorize their meanings defined by the Grid specification. But don’t worry, there aren’t many of them.
The element on which display: grid is applied. It’s the direct parent of all the grid items. In this example container is the grid container.
The children (i.e. direct descendants) of the grid container. Here the item elements are grid items, but sub-item isn’t.
The dividing lines that make up the structure of the grid. They can be either vertical (“column grid lines”) or horizontal (“row grid lines”) and reside on either side of a row or column. Here the yellow line is an example of a column grid line.
The space between two adjacent row and two adjacent column grid lines. It’s a single “unit” of the grid. Here’s the grid cell between row grid lines 1 and 2, and column grid lines 2 and 3.
The space between two adjacent grid lines. You can think of them like the columns or rows of the grid. Here’s the grid track between the second and third row grid lines.
The total space surrounded by four grid lines. A grid area may be composed of any number of grid cells. Here’s the grid area between row grid lines 1 and 3, and column grid lines 1 and 3.

An HTML version of this review is part of the movie section of Culture Club Central, a website which will hopefully be online some day. If you have comments on this I might include them at the site. Please excuse bad english, it's not my mother tongue.
The Hitcher (Review by Philipp Lenssen/<EMAIL_ADDRESS>Jan. 1998)
"Out on the desert highway, the rule of thumb has a different meaning..."
The story here is basically good man against evil man. Jim Halsey (C. Thomas Howell) is driving a car through Texas and takes up hitcher John Ryder with the words "My mother told me never to do this", foreshadowing the tragedy ahead.  Little does Jim Halsey know when he bravely throws the hitcher out of the car that by escaping death he just qualified himself for his worst nightmare. The hitcher found someone to play a deadly game with...
The nice twist here is the Hitchcock-like innocent hunted as murder theme... when he cannot even turn to the police, the hero is suddenly very alone. The other interesting thing is the neverending nightmare, when you're never sure when it's over, and you never quite get behind the hitchers mask and now what it's all about anyway. The Hitcher's brilliant play (Robert Townsend writes "C. Thomas Howell declared later that he was actually frightened of Hauer throughout the filming, and not just acting") and shooting makes this for an atmospheric, unforgettable experience.
The Halsey Ryder relation-ship
During the course of the movie we see that the hitcher John Ryder focusses on Jim Halsey. Other peolpe surrounding Halsey are massacred, but he himself is even getting help, and Ryder tells him how to do things. Ryder's not making it easy for Halsey but he's also making sure there's a fair chance for Halsey to always escape.
Roger Ebert states in his 1986 review of The Hitcher that "there is something sadomasochistic going on between the two men". He also writes "this movie is diseased and corrupt. I would have admired it more if it had found the courage to acknowledge the real relationship it was portraying". Ryder might be sadistically enjoying his actions, but I don't see Halsey getting into this situation deliberately, or enjoying it, or not wanting to get out of it.
"'The Hitcher' begins and ends with the same sound: a match being struck, flaring into flame.  At the end of the film, the sound is made by the hero, a young man whose life has been spared so that he can become the special victim of the hitchhiker."
What Ebert describes here is wrong. The person striking a match at the beginning and at the end is both times the hero Halsey. I don't want to analyze this symmetry (we'll see many cigarettes lit during the movie, which is not too absurd when the characters smoke), but it shows Ebert uses false proof. Still, "there is something strange going on between the two of [them]", as a police man tells us near the end.
Keith Myles quotes "Derek Winnert's assertion that the relationship of the protagonists is dominated by latent homosexuality". There is a subtle sexual undertone in the way Rutger Hauer plays the character, and it emphasizes Ryder's evil ironic humor. But not only do we see him touching Halsey, we see him kiss the little girl in the car and the same tender scheme towards Nash. A cat's playing with the mouse before striking, showing a certain elegance which might arouse sympathy in us... it makes the movie even more ambigue and intriguing.
The hitcher chooses a male counterpart because he is looking for both a contrast and reflection. The contrast is that Halsey is the good man (you can't play a game without conflict), and the reflection is Halsey's youthful male energy. It'll become a teacher - pupil/ master - apprentice relationship. Halsey's survival skill is trained. The pupil chosen has to be good enough to be able to understand the scope of evilness he sees and to challenge his master.
At the beginning: Halsey: "What do you want?" Ryder: "I want you to stop me."
 Ryder: "You're a smart kid, figure it out."
When Jim Halsey's girl Nash is being is tied between the two trucks, Ryder makes Halsey put the gun against his face, he wants Halsey to pull the trigger and kill him. It's again very clear who's making up the rules of this game. When Halsey can't do it, Ryder is disappointed and suddenly stops to smile: "You're useless waste." He punishes him by killing off Nash (the importance of Nash to Ryder is only in her relation towards Halsey: For Ryder she is functioning as hostage and "price to pay" for Halsey here).  When he steps on the gas it becomes, though not graphically violent, a truly horrible scene. We're put back and shocked by the reminder that the hitcher is not following any convention - Ebert thinks this is "so grotesquely out of proportion [...] that it suggests a deep sickness at the screenplay stage", which I would rephrase by saying it suggests a deep sickness of the hitcher, and suggesting anything else would be glorifying mass murder.
When Nash is killed, the screen fades to black and this event will result in a turning point in Halsey's character. Halsey knows that the killer will not stop until he's put to death by him; he understands the perverted game and the fact that he has to play it (he's clearly forced to act). When the police is questioning the hitcher, Halsey enters. He touches Ryder and spits him in the face, and in that scene Ryder knows that Halsey has understood the game and hates Ryder for it.
Later when Halsey is sitting in a police car, he tells the police man: "You'll never hold him." "There's something I gotta do." When we look back on Halsey's character we see this is his second turning point in the movie. The first crucial moment was Halsey resisting the urge to commit suicide when he put the gun up his head earlier on: by choosing to live on he accepted to be the hitcher's contrahent and play his game.
After what happened Jim Halsey does indeed feel relieved when he gets his revenge. It's true that a bond is created during the move, the unyfing element of hunter and prey. The hero ends this game - he had to switch the roles and became the hunter for this purpose.
At the police station Ryder says he feels tired. His suicidal rampage makes clear he's tired of life. Shane R. Burridge writes about the possible salvation and succession motif: "Has [Ryder] found a way to end his curse--or worse, pass it on--by goading [Halsey] to end his life? (When he places coins on [Halsey]'s eyes, he is suggesting that he is damned). Significantly, during their final confrontation, [Ryder] drops a chain to the ground and smiles: he is free at last."
When John Ryder laughs as he knows he's going to be killed now, this final satisfaction is triggered by Halsey's proof of a learned lesson (the relevance is not in eventual masochism): The teaching was a success, because Halsey accepted the god-like responsibility of playing judge over Ryder's life. The hitcher's game of survival, and his archaic view of an amoral world which seperates the strong and the weak, has been absorbed by his apprentice. He didn't want to kill Halsey, he wanted to make him "gaze into the abyss", so that his ego projects itself onto Halsey.

06 May 2015
Algolia's DNA is really about performance. We want our search engine to answer
relevant results as fast as possible.
To achieve the best end-to-end performance we've decided to go with JavaScript
since the total beginning of Algolia. Our end-users search using our REST API
directly from their browser - with JavaScript - without going through the
websites' backends.
Our JavaScript & Node.js API clients were implemented 2 years ago and were now
lacking of all modern best practices:
- not following the error-first or callback-last conventions;
- inconsistent API between the Node.js and the browser implementations;
- no Promise support;
- Node.js module named algolia-search, browser module named algoliasearch;
- cannot use the same module in Node.js or the browser (obviously);
- browser module could not be used with browserify or webpack. It was exporting multiple properties directly in the window object.
This blog post is a summary of the three main challenges we faced while
modernizing our JavaScript client.
tl;dr;
Now the good news: we have a new isomorphic JavaScript API
client.
Isomorphic JavaScript apps are JavaScript applications that can run both
client-side and server-side.
The backend and frontend share the same code.
isomorphic.net
Here are the main features of this new API client:
If you were using our previous libraries, we have migration guides for both
Node.js and the
browser.
Challenge #1: testing
Before being able to merge the Node.js and browser module, we had to remember
how the current code is working. An easy way to understand what a code is
doing is to read the tests. Unfortunately, in the previous version of the
library, we had only one test. One test was
not enough to rewrite our library. Let's go testing!
Unit? Integration?
When no tests are written on a library of ~1500+
LOC,
what are the tests you should write first?
Unit testing would be too close to the implementation. As we are going to
rewrite a lot of code later on, we better not go too far on this road right
now.
Here's the flow of our JavaScript library when doing a search:
- initialize the library with
algoliasearch()
- call
index.search('something', callback)
- browser issue an HTTP request
callback(err, content)
From a testing point of view, this can be summarized as:
- input: method call
- output: HTTP request
Integration testing for a JavaScript library doing HTTP calls is interesting
but does not scale well.
Indeed, having to reach Algolia servers in each test would introduce a shared
testing state amongst developers and continuous integration. It would also
have a slow TDD feedback because of heavy network usage.
Our strategy for testing our JavaScript API client was to mock (do not run
away right now) the XMLHttpRequest object.
This allowed us to test our module as a black box, providing a good base for a
complete rewrite later on.
This is not unit testing nor integration testing, but in between. We also
planned in the coming weeks on doing a separate full integration testing suite
that will go from the browser to our servers.
faux-jax to the rescue
Two serious candidates showed up to help in testing HTTP request based
libraries
Unfortunately, none of them met all our requirements. Not to mention, the
AlgoliaSearch JavaScript client had a really smart failover request strategy:
This seems complex but we really want to be available and compatible with
every browser environment.
- Nock works by mocking calls to the Node.js http module, but we directly use the XMLHttpRequest object.
- Sinon.js was doing a good job but was lacking some XDomainRequest feature detections. Also it was really tied to Sinon.js.
As a result, we created algolia/faux-jax. It is now pretty stable and can mock XMLHttpRequest, XDomainRequest and
even http module from Node.js. It means faux-jax is an isomorphic HTTP
mock testing tool. It was not designed to be isomorphic. It was easy to add
the Node.js support thanks to moll/node-mitm.
Testing stack
The testing stack is composed of:
The fun part is done, now onto the tedious one: writing tests.
Spliting tests cases
We divided our tests in two categories:
- simple test cases: check that an API command will generate the corresponding HTTP call
- advanced tests: timeouts, keep-alive, JSONP, request strategy, DNS fallback, ..
Simple test cases
Simple test cases were written as table driven
tests:
It's a
simple JavaScript file, exporting test cases as an
array
Creating a testing stack that understands theses test-cases was some work. But
the reward was worth it: the TDD feedback loop is great. Adding a new feature
is easy: fire editor, add test, implement annnnnd done.
Advanced tests
Complex test cases like JSONP fallback, timeouts and errors, were handled in
separate, more advanced tests:
Here we test
that we are using JSONP when XHR fails
Testing workflow
To be able to run our tests we chose
defunctzombie/zuul.
Local development
For local development, we have an npm test task that will:
- launch the browser tests using phantomjs,
- run the Node.js tests,
- lint using eslint.
You can see the task in the
package.json. Once run it looks like this:
640 passing
assertions and counting!
But phantomjs is no real browser so it should not be the only answer to "Is my
module working in browsers?". To solve this, we have an npm run
dev task that
will expose our tests in a simple web server accessible by any browser:
All of theses
features are provided by defunctzombie/zuul
Finally, if you have virtual machines, you can
test in any browser you want, all locally:
Here's a
VirtualBox setup created with
xdissent/ievms
What comes next after setting up a good local development workflow? Continuous
integration setup!
Continuous integration
defunctzombie/zuul supports running
tests using Saucelabs browsers. Saucelabs provides
browsers as a service (manual testing or Selenium automation). It also has a
nice OSS plan called Opensauce. We patched
our .zuul.yml configuration file
to specify what browsers we want to test. You can find all the details in
zuul's wiki.
Now there's only one missing piece: Travis CI.
Travis runs our tests in all browsers defined in our .zuul.yml file. Our
travis.yml looks like this:
All platforms are tested using a travis build
matrix
Right now tests are taking a bit too long so we will soon split them between
desktop and mobile.
We also want to to tests on pull requests using only latest stable versions of
all browsers. So that it does not takes too long. As a reward, we get a nice
badge to display in our
Github readme:
Gray color
means the test is currently running
Challenge #2: redesign and rewrite
Once we had a usable testing stack, we started our rewrite, the V3
milestone on Github.
Initialization
We dropped the new AlgoliaSearch() usage in favor of just
algoliasearch(). It allows us to hide implementation details to our API
users.
Before:
new AlgoliaSearch(applicationID, apiKey, opts);
After:
algoliasearch(applicationID, apiKey, opts);
Callback convention
Our JavaScript client now follows the error-
first and callback-last conventions. We had to break some methods to
do so.
Before:
client.method(param, callback, param, param);
After:
client.method(params, param, param, params, callback);
This allows our callback lovers to use libraries like
caolan/async very easily.
Promises and callbacks support
Promises are a great way to handle the asynchronous flow of your application.
Promise partisan? Callback connoisseur? My API now lets you switch between
the two! http://t.co/uPhej2yAwF (thanks
@NickColley!)
— pouchdb (@pouchdb) March 10,
2015
We implemented both promises and callbacks, it was nearly a no-brainer. In
every command, if you do not provide a callback, you get a Promise.
We use native promises in compatible
environments and
jakearchibald/es6-promise as
a polyfill.
AlgoliaSearchHelper removal
The main library was also previously exporting window.AlgoliaSearchHelper to
ease the development of awesome search UIs. We externalized this project and
it now has now has a new home at algolia/algoliasearch-helper-
js.
UMD
UMD: JavaScript modules that run anywhere
The previous version was directly exporting multiple properties in the
window object. As we wanted our new library to be easily compatible with a
broad range of module loaders, we made it UMD
compatible. It means our library can be used:
This was achieved by writing our code in a
CommonJS style and then use the
standalone build feature of browserify.
see
browserify usage
Multiple builds
Our JavaScript client isn't only one build, we have multiple builds:
Previously this was all handled in the main JavaScript file, leading to unsafe
code like this:
How do we solve this? Using inheritance! JavaScript prototypal inheritance is
the new code smell in 2015. For us it was a good way to share most of the code
between our builds. As a result every entry point of our builds are inheriting
from the src/AlgoliaSearch.js.
Every build then need to define how to:
Using a simple inheritance pattern we were able to solve a great challenge.
Example of
the vanilla JavaScript build
Finally, we have a build script that
will generate all the needed files for each environment.
Challenge #3: backward compatibility
We could not completely modernize our JavaScript clients while keeping a full
backward compatibility between versions. We had to break some of the previous
usages to level up our JavaScript stack.
But we also wanted to provide a good experience for our previous users when
they wanted to upgrade:
- we re-exported previous constructors like window.AlgoliaSearch. But we now *throw** if it's used
- we wrote a clear migration guide for our existing Node.js and JavaScript users
- we used npm deprecate on our previous Node.js module to inform our current user base that we moved to a new client
- we created legacy branches so that we can continue to push critical updates to previous versions when needed
Make it isomorphic!
Our final step was to make our JavaScript client work in both Node.js and the
browser.
Having separated the builds implementation helped us a lot, because the
Node.js build is a regular build only using the http module from Node.js.
Then we only had to tell module loaders to load index.js on the server and
src/browser/.. in browsers.
This last step was done by configuring browserify in our
package.json:
the browser
field from
browserify also works in webpack
If you are using the algoliasearch module with browserify or webpack, you
will get our browser implementation automatically.
The faux-jax library is released under MIT like all our open source
projects. Any feedback or improvement idea are welcome, we are dedicated to
make our JS client your best friend :)

Browsing the cumbersome interfaces of government websites in the lookout for
reliable data can be a very frustrating experience. It's full of specific
terminology and there's not a government website that looks the same. It's
like each time you want to use a car, you have to learn to drive all over
again.
Connect ideas with economic insight in a matter of seconds
That's what Quadrant.io is for.
Solving the frustration anyone who makes their points with facts encounters
when routinely performing data search. It offers them with the fastest and
easiest way to find and chart economic data from trusted sources.
Acknowledging that it can quickly become a nightmare to find reliable
information scattered all over the web,
Quadrant is on a mission to shorten
any data search to seconds. So that data users can spend less time finding
data and more time analysing it.
To keep this promise, Quadrant provides data users with an intuitive platform
that aggregates more than 400,000 indicators from over 1,000 public sources,
and keep them updated in real time. A powerful search allowing any user to
find exactly what they are looking for even if they do not use economists'
jargon is a must-have functionality in such a service.
And Algolia stood out as the perfect search solution for Quadrant.
Provide a rewarding search experience to End-Users
First because of** the rewarding search experience it allows to deliver to its
users.**
Algolia surfaces data relevant to people's search in milliseconds, showing the
most appropriate results from the very first keystroke.
It enables to search across different entry points corresponding to the
different attributes describing data series (release date, source).
That wasn't possible with other search solutions they tested before. After
implementing Algolia, Quadrant.io received nice feedback from their customers,
saying that "search was much more comfortable, much more intuitive".
Algolia empowers anyone to be a search expert
Second, because of the simple experience it is to deploy Algolia on their web
app. Back-end documentation and customer support was a major help: it took
them less than a week to implement instant search, including relevance
tweaking and front-end development. As Dane Vrabrac, co-founder of Quadrant.io
concluded "with Algolia, it's awesome all the stuff I can do as a non
developer !"

At Algolia, we allow developers to provide a unique interactive search
experience with as-you-type search, instant faceting, mobile geo-search and on
the fly spell check.
Our Distributed Search Network aims at removing the impact of network latency
on the speed of search, allowing our customers to offer this instant
experience to all their end-users, wherever they may be.
Every millisecond matters
We are obsessed with speed and we're not the only ones: Amazon found out that
100ms in added latency cost them 1% in sales. The lack of responsiveness for
a search engine can really be damaging for one's
business. As
individuals, we are all spoiled when it comes to our search expectations:
Google has conditioned the whole planet to expect instant results from
anywhere around the world.
We have the exact same expectations with any online service we use. The thing
is that for anyone who is not Google, it is just impossible to meet these
expectations because of the network latency due to the physical distance
between the service backend that hosts the search engine and the location of
the end-user.
Even with the fastest search engine in the world, it can still take hundreds
of milliseconds for a search result to reach Sydney from San Francisco. And
this is without counting the bandwidth limitations of a saturated oversea
fiber!
How we beat the speed of light
Algolia's Distributed Search Network (DSN) removes the latency from the speed
equation by replicating your indices to different regions around the world,
where your users are.
 DSN allows
you to distribute your search among 12 locations including the US,
Australia, Brazil, Canada, France, Germany, Hong Kong, India, Japan, Russia,
and Singapore. Thanks to our 12 data centers, your search engine can now
deliver search results under 50ms in the world's top markets, ensuring an
optimal experience for all your users.
How you activate DSN
Today, DSN is only accessible to our Starter, Growth, Pro and Enterprise plan
customers. To activate it, you simply need to go in the "Region" tab at the
top of your Algolia dashboard and select "Setup DSN".
You will then be displayed with a map and a selection of your top countries in
terms of search traffic. Just select our DSN data centers on the map and see
how performance in those countries is optimized.
Algolia will then automatically take care of the distribution and the
synchronization of your indices around the world. End-users' queries will be
automatically routed to the closest data center among those you've selected,
ensuring the best possible experience. Algolia DSN delivers an ultra low
response time and automatic fail-over on another region if a region is down.
It is that simple!
Today, several services including HackerNews, TeeSpring, Product Hunt and
Zendesk are leveraging Algolia DSN to provide faster search to their global
users.

Exactly a year ago, we began to power the Hacker News search engine (see our
blog post. Since then,
our HN search project has grown a lot, expanding from 20M to 25M indexed
items, and serving** from 900K to 30M searches a month**.
In addition to hn.algolia.com we're also providing
build various readers or monitor tools and we love the applications you're
building on top of us. The community was also pretty active on
GitHub, requesting improvements
and catching bugs... keep on contributing!
Eating our own dog food on HN search
We are power users of Hacker News and there isn't a single day we don't
use it. Being able to use our own engine on a tool that is so important to us
has been a unique opportunity to eat our own dog food. We've added a
lot of API features during the year but unfortunately didn't have the time to
refresh the UI so far.
One of our 2015 resolutions was to push the envelope of the HN search UI/UX:
- make it more readable,
- more usable,
- and use modern frontend frameworks.
That's what motivated us to release a new experimental version of HN
Search. Try it out and tell us what
you think!
Applying more UI best practices
We've learned a lot of things from the
comments of the users of the
previous version. We also took a look at all the cool
apps built on top of our API. We wanted to
apply more UI best practices and here is what we ended with:
Focus on instantaneity
The whole layout has been designed to provide an instant experience, reducing
the wait time before the actual content is displayed. It's also a way to
reduce the number of mouse clicks needed to access and navigate through the
content. The danger with that kind of structure can be to end up with a
flickering UI where each user action redraw the page, activating unwanted
behaviors and consuming a huge amount of memory.We focused on a smooth
experience. Some of the techniques used are based on basic performance
optimizations but in the end what really matters for us is the user's
perception of latency between each interactions, more than objective
performance. Here are some of the tricks we applied:
- Toggle comments: we wanted the user to be able to read all the comments of a story on the same page, our API on top of Firebase allowed us to load and display them with a single call.
- Sticky posts: in some cases we are loading up to 500 comments, we wanted the user to be able to keep the information of what he is reading and easily collapse it, so we decided to keep the initial post on top of the list.
- Lazy-loading of non-cached images: when you are refreshing the UI for each request you don't want every thumbnail to flick on the UI when loading. So we applied a simple fade to avoid that. But there is actually no way to know if an image is already loaded or not from a previous query. We manage to detect that with a small timeout.
- Loading feedback: the most important part of a reactive UI is to always give the user a feedback on the state of the UI. We choose to add this information with a thin loading bar on top of the page.
- Deferring the load of some unnecessary elements: this one is about performance. When you are displaying about 20 repeatable items on each keypress you want them as light as possible. In our case we are using Angular.js with some directives which were too slow to render. So we ended up rendering them only if the user interact with them.
- Cache every requests: It's mainly about the backspace key. When a user want to modify his query by removing some characters you don't want to make him wait for the result: that's cached by the Algolia JS API client.
Focus on readability
We've learned a lot from your comments while releasing our first HN Search
version last year. Readability of the search results must be outstanding to
allow you to quickly understand why the results are retrieved and what they
are about. We ended up with 2 gray colors and 2 font weights to ease the
readability without being too distracting.
Stay as minimal as possible
If you see unnecessary stuffs, please tell us. We are not looking for the most
'minimal' UI but for the right balance between usability and minimalism.
Sorting & Filtering improvements
Most HN Search users are advanced users. They know exactly what they are
searching for and want to have the ability to sort and filter their results
precisely. We are now exposing a simple way to either sort results by date or
popularity in addition to the period filtering capabilities we already had.
Inlined comments
We thought it could make a lot of sense to be able to read the comments of a
story directly from the search result page. Keeping in mind it should be super
readable, we went for indentations & author colored avatars making it really
clear to understand who is replying.
Search settings
Because HN Search users are advanced users, they want to be able to customize
the way the default ranking is working. So be it, we've just exposed a subset
of the underlying settings we're using for the search to let you customize it.
Front page
Since Firebase is providing the official API of Hacker News, fetching the
items currently displayed on the front page is really easy. We decided to pair
it with our search, allowing users to search for hot stories & comments
through a discreet menu item.
Starred
Let's go further; what about being able to star some stories to be able to
search in them later? You're now able to star any stories directly from the
results page. The stars are stored locally in your browser for now. Let us
know if you find the feature valuable!
Contribution
As you may know, the whole source code of the HN Search website is open-source
and hosted on GitHub. This new version is still based on a Rails 4 project and
uses Angular.js as the frontend framework. We've improved the README to help
you being able to contribute in minutes. Not to mention: we love pull-
requests.
Now is starting again the most important part of this project, user testing. We count on you to bring us the necessary information to make this search your favorite one.

By working every day on building the best search engine, we've become obsessed
with our own search experience on the websites and mobile applications we use.
We're git addicts and love using GitHub to store every single idea or project
we work on. We use it both for our private and public repositories (12 API
clients, HN
Search or various

s. We use every day its search
function and we decided to re-build it the way we thought it should be. We're
proud to share it with the community via this Chrome
extension. Our Github Awesome Autocomplete

search functionality.

Features
The Chrome extension replaces GitHub's search bar and add autocomplete
capabilities on:
How does it work?
We continuously retrieve the most watched repositories and the last active
users using GitHub Archive dataset. Users and
repositories are stored in 2 Algolia indices: users and repositories. The
queries are performed using our JavaScript API
client and the
autocomplete menu is based on Twitter's
typeahead.js library.
The underlying Algolia account is replicated in 6 regions using our
DSN feature, answering every query in 50-100ms
wherever you are (network latency included!). Regions include US West, US
East, Europe, Singapore, Australia & India.
Exporting the records from GitHub Archive
We used GitHub's Archive dataset to export top repositories and last active
users using Google's BigQuery:
;; export repositories
SELECT
a.repository_name as name,
a.repository_owner as owner,
a.repository_description as description,
a.repository_organization as organization,
a.repository_watchers AS watchers,
a.repository_forks AS forks,
a.repository_language as language
FROM [githubarchive:github.timeline] a
JOIN EACH
(
SELECT MAX(created_at) as max_created, repository_url
FROM [githubarchive:github.timeline]
GROUP EACH BY repository_url
) b
ON
b.max_created = a.created_at and
b.repository_url = a.repository_url
;; export users
SELECT
a.actor_attributes_login as login,
a.actor_attributes_name as name,
a.actor_attributes_company as company,
a.actor_attributes_location as location,
a.actor_attributes_blog AS blog,
a.actor_attributes_email AS email
FROM [githubarchive:github.timeline] a
JOIN EACH
(
SELECT MAX(created_at) as max_created, actor_attributes_login
FROM [githubarchive:github.timeline]
GROUP EACH BY actor_attributes_login
) b

Increase the verification done in the code.
Support private
to be sure your code is used from where it is
intented.  All that lead to faster bug fixes. so better code.
Thus you measure more accuratly what your code is actually doing. Monitor Garbage Collection. Monitor Global Variables. Monitor all you can. Good measures leads to better decision on which action to take.
No new language to learn. No compilation to javascript. Only good old javascript. Javascript is open standard and run everywhere. You can't beat that.
With Better.js, it is possible to pass attributes to class. You can define which functions is private or not, same for properties. You can apply strong typing to arguments and better.js check the validity of each arguments passed to your constructor. You can apply strong typing to properties the same way.
With Better.js, you can define the strong typing for your arguments and better.js check the validity of each arguments passed to your function. It is the same for strong typing for the returned value. If this function is part of a class, you can declare it as private thus only this class will be able to use it.
With better.js you can have strong typing for your properties. So you define the type allowed for your property, and better.js check it everytime the value is modified. If this property is part of a class, you can declare it as private thus only this class will be able to use it.
npm install better.js
<script src="better.js"></script>
bower install better.js
Better.js adds private/public support to javascript. It is possible to declare a property or a function as private, and Better.js will check it for you. If it is used from outside the class, it will stop immediatly.
// definition of the class var Cat = function(){ this._name = 'kitty' } // Make it Better.js with privatize Cat = Bjs.Class(Cat, { privatize : true }) // Get an instance of this class var cat = new Cat() // Try to display a private property from outside console.log("cat's name is", cat._name) // Exception Thrown // 'access to private property _name' // Thanks to Better.js! // In plain javascript, it would silently ignore the // issue and display the value
// definition of the function var add = function(a, b){ return a + b; } // Make it better.js add = Bjs.Function(add, { arguments : [Number, Number], return : [Number] }) // Try to display pass invalid arguments type add('hello', 'world') // Exception Thrown // 'Invalid argument. it should be a Number' // Thanks to Better.js! // In plain javascript, it would silently ignore the // issue and execute the code.
Better.js adds strong typing support to javascript. It is possible to declare the allowed type of each property. If somebody set it to a wrong type, it is stopped immediatly. The same for function arguments, you define the allowed types and better.js will make sure they are respected.

“Who Cares about Elegance?” The Role of Aesthetics in Programming Language Design
Bruce J. McLennan
[https://web.eecs.utk.edu/~bmaclenn/papers/Elegance.html]
the main analogy is structural engineering, with a parallel to Billington’s The Tower and the Bridge
according to billington, there are 3 E’s:
- efficiency (scientific issue, related to the measurement and use/waste of resources such as runtime memory usage, battery life, etc.)
- elegance (symbolical, trying to minimize, somehow, complexity. elegance is the answer to underdetermination)
- economy (social issue, trying to maximize social benefit vs. cost, so this means it’s actually public-facing, not so much source-code facing (or can we even tell that from the source code?). different PLs shift priorities based on the socio-economic context)
The design looks unbalanced if the forces are unbalanced, and the design looks stable if it is stable. By restricting our attention to designs in which the interaction of features is manifest - in which good interactions look good, and bad interactions look bad - we can let our aesthetic sense guide our design
How do you acquire this vision? Practice.

It's almost gauche to express a platitude like "music connects us all", yet the universal nature of music is truly astonishing. It doesn't matter if you're a music maker tapping away on Native Instruments gear in a dark room, an aficionado with neighbour-bothering speakers or simply someone who just likes something pleasant playing through their bluetooth headphones – we all hanker after music. But why?
Kathryn Lawrence finds out that our brains are hard-wired to respond to music in certain predictable ways – and that we can hack our brains with sound...
Music can do some powerful things: make your toes tap, hips sway, or hack your brain.
No, this isn't about ear worms, which feel like a sonic DDoS attack. It's about using the power of music to change your brain state.
Throbbing 100 Hz beats may not be topping the charts any time soon, (but some people listen to weirder ambient sounds in the basement techno clubs of Berlin, and call that music...). These sound-based technological experiments are designed to change your brain state or induce different feelings: from subliminal messages in pop music, to binaural beats and ASMR, soft brain hacking tech is here with the power of music.
Mind Control Music
The trope of Mind Control Music describes music that can induce a hypnotic state or propel the listener to perform some kind of behavior through subliminal messages. Descended from stories dating as far back as the Sirens of Greek mythology, or the Middle Ages' cautionary tale of the Pied Piper, they illustrate the compelling power of music. But can it really hack your body and mind?
Fundamentalist Christian groups have long professed the belief that rock music influences bad behavior, going so far as to say that it causes teens to worship the devil. After the 1990 case against Judas Priest, who were sued for supposedly including backmasked messages urging suicide on one of their albums, psychologists have taken on serious study of whether subliminal messaging in music, via backwards messages or other means, is possible.
In a chapter of 2005's Psychological Sketches entirely dedicated to subliminal messages, John Vokey from the University of Lethbridge found "simply no evidence for effective subliminal persuasion in film or video, advertising, self-help audiotapes, or rock music, and there is certainly no theoretical basis to expect it."
Of course, the opinions of psychologists will never stop the endless tide of conspiracy theorists trying to find evidence of attempts at mass brainwashing in every new pop music release.
Katy Perry's most recent summer hit, "Chained To The Rhythm," while hilariously straightforward in its messaging about being self-aware of the mind-numbing effects of pop music always urging us to spend money, strive to procreate, and submit our wills to the machine of capitalism, may have a grain of truth in it.
A study presented at the 2012 Society for Neuroscience meeting found that groups that are exposed to the same rhythmic sounds not only move together in rhythm, but also think in rhythm together.
It may not be as obvious an influence as flashing signs saying "Eat popcorn" and "Drink Coca-Cola" but could be used to facilitate communication and cooperation among large groups.
Sound Waves & Brain Waves: The Science
There are five types of brain waves that most people emit regularly during normal brain activities (like living, sleeping, working, etc.): alpha, beta, delta, gamma, and theta waves.
Gamma waves have the highest frequency, from 40 to 100 Hz, and are important for learning, memory, and information processing. Next are beta waves, between 12 and 40 Hz, used for critical thinking, reading, writing, and socializing. Alpha waves, between 8 Hz and 12 Hz, are emitted when relaxing, and theta waves, between 4 and 8 Hz are emitted during sleep or creative activities. Finally delta waves, the slowest, between 0 and 4 Hz, are emitted during deep sleep, and are essential to unconscious bodily functions like heartbeat and digestion.
Essentially, the idea behind brain hacking with sound waves is that you can expose your brain to frequencies that will cause it to produce more of one of these types of waves due to the entrainment phenomenon.
And how do those frequencies get to your brain? Through your ears of course!
Binaural audio has been the focus of many studies (see Auditory Beat Stimulation and its Effects on Cognition And Mood States and Binaural beat technology in humans: a pilot study to assess neuropsychologic, physiologic, and electroencephalographic effects among others) that attempt to treat anxiety, depression, ADHD, or support claims of binaural beats for controlling and enhancing brain power. The theory is that when you play an audio track in each ear with a slightly different frequency, your brain itself produces a tone in between the two frequencies to compensate, and that in doing so, you produce brain waves of that frequency.
Although this effect has yet to be definitively proven, people use binaural beats to improve their concentration while studying, quickly achieve a state of meditation, or even produce altered, drug-like states.
ASMR & Braingasms
Another barely-explained audio-induced phenomenon that has been sweeping the internet is ASMR, short for the autonomous sensory meridian response. This formal name for the feeling, introduced in 2010, refers to a tingling sensation on the scalp, neck, and sometimes back, while listening to soft sounds such as whispering, paper crinkling, tapping, and many others. Often there is an element of role play, as other common triggers include hair cutting, massage, and other grooming-related relaxing activities.
Often recordings used to induce the "brain orgasm" of ASMR are recorded binaurally, so that users wearing headphones can hear the proximity and direction of the sounds, which enhances the effect.
And although many ASMR triggers are associated with intimacy, such as speaking softly or lightly stroking objects, members of the ASMR community insist that the experience is not sexual. For a non-tingler, these videos which are intended to help you relax, produce a euphoric sensation, or get to sleep faster, can seem fetishistic or unsettling in their specificity. But when it works, it really works, as evidenced by the almost one million subscribers to the most popular "ASMRtist" on YouTube, Gentle Whispering.
Soft Brain Hacking
Try it now and feel the power of music
While it may take some special circumstances, or a lot more research into how and why the brain responds to music and auditory stimulation, we know enough to make an effort towards designing music that not only feels, but also sounds good. This is the goal of the Sync Project: along with Manchester's Marconi Union, they are attempting to create the world's most relaxing music. Using a smartphone app which also measures your heart rate, the program called Unwind can help you relax and support their research into using music as medicine.
Marconi Union's song "Weightless" is said to be able to reduce anxiety by up to 65%, according to a study by Mindlab International. Attaching sensors monitoring changes in heart rate, blood pressure, breathing, and brain activity, they found that "Weightless" was more effective at calming the body than the other songs by 11%.
Inc.'s Melanie Curtin compiled a playlist of all of the most relaxing music used in the experiments below, so if you would like to enjoy some soft brain hacking, try it now and feel the power of music:

Bitwig Studio 3.1 promises a tuned-up selection of pitch features
by Ben RogersonBitwig Studio 3.1 promises a tuned-up selection of pitch features
While Bitwig Studio 3 focused on The Grid, the DAW’s new modular sound design environment, version 3.1 is stuffed with expanded pitch features.
To begin with, there’s a new Note FX device, Micro-pitch, which can be used to retune note streams in a variety of ways. Pitch 12, meanwhile, is a new modulator that provides a modulation signal when a note is pressed. There’s now a Transpose module in The Grid, and the window footer in Bitwig Studio now shows frequency and pitch.
There are editing and workflow improvements, too, and a variety of feature additions across the board.
Find out more on the Bitwig website; the Bitwig Studio 3.1 update is currently in beta, and is available to all customers with a license and active upgrade plan. The full release is expected in the next few weeks.


New Aston Martin DBX: pricing for South Africa confirmed…
by Ryan BubearAston Martin South Africa has confirmed its new DBX will be priced from R3,6-million when it launches locally early in 2020. For reference, the Lamborghini Urus starts at R3 495 000.
That pricing means the new DBX will slot into Aston Martin’s local range above the Vantage V8 and Rapide S but below the DBS Superleggera. In the four-strong DB11 line-up, only the V8-powered coupé will be less expensive than the SUV.
The DBX, which is built at Aston Martin’s new manufacturing facility in Wales, is both the first SUV and the first full five-seater in the British firm’s 106-year history.
Power comes from a Mercedes-AMG-sourced twin-turbo 4,0-litre V8 shared with the DB11 and Vantage, although here it offers 405 kW and 700 N.m (and a “sound character that is unquestionably Aston Martin”). That’s enough, claims Aston Martin, for a sprint from standstill to 100 km/h in 4,5 seconds and a top speed of 292 km/h.
A nine-speed torque convertor automatic transmission sends that oomph to all four wheels, while adaptive air suspension combines with a 48 V electric anti-roll control system and electronic adaptive dampers to lend the DBX what Aston terms “a huge breadth of ability”.
Inside, the British company claims “class-leading” levels of headroom and legroom, as well as 632 litres of boot space. There’s also a full-length glass panoramic roof and frameless door glass, along with full-grain leather trim, plenty of Alcantara and a range of wood, composite and metal veneers.
In terms of technology, the DBX features a 10,25-inch TFT screen in the centre console as well as a 12,3-inch TFT screen ahead of the driver. Apple CarPlay comes as standard, as does a 360-degree camera system and ambient lighting that offers 64 different colours in two zones.

Have you all remember the rock paper scissors game that we used to play in our childhood. I know this is not very common game in Indian house holds 😂.
One good day while out of blue I got a thought to develop this game on our mobile devices.
Mobile devices are very ubiqutous now a days. All most all have one mobile devices in their hand. So, I'm very much keen about mobile techologies. Because of many reason from which I'd list down a few of them:
- Data is the new oil and they give lot of data.
- In my opinion the next big technology will be IoT. It may be because of 5G or any other factor. Already lot of big technology and manufacturing companies are using it alot
- The list goes on
The list is not comprehensive but it gives you an overall picture.
Brainstroming
The big picture of my game is to build a game that can be played with two remotely connected people.
Here we go. I thought about the game rules. The use has to point his mobile's camera to their hand. On count of 3 the user makes a guesture. My algorithm should recognise the gesture and classify it into one of the rock , paper, scissor or None of the above.
Initially, thinking of a two player game. One will be the winner. Alright! Now I'll explain about my finding on the algorithm and planning.
Research
Recognising the Hand Guesture
Thinking on what to do next and how do I proceed 🤔. I googled a lot. Then my results are the following:
The OpenCV Way
I've to found out that recognising the hand guesture is a little bit easy using OpenCV. Many have done experiments on recognising the Hand guestures using OpenCV. Most of them recognised the numbers using hand guestures. Other than numbers few tried recognising the symbols like Ok👍. Perfect👌 etc.,
I'll tell you how it works:
- We detect a particular colour in the frame.
- We detect countour(edges) and hulls in the image.
- Using the angle between the hulls we will determine how many fingers and opened. If there are 2 fingers opened, it will be scissors, if 5 it's paper and if it's 0 it's stone.
But this needs a plane background with less disturbance. I can make a game, but I don't know how well it will be received. On this conclusion I thought of the Machine Learning way
The Machine Learning way
With remarks from opencv I started looking into tensorflow lite
Communicating with two users
And there are lot of things to cover in this blog. I'll keep updating this blog.


For this challenge, I wanted to experiment with color blending and discover all the different ways to blend color using p5.js. I played around with lerpColor() and hue to create different effects across my sketches. For this sketch, I literally created a color blender! I felt this was a good place to start using lerpColor() to find the halfway point between two colors. Adding in the blender graphic and juice effects just made the experience a little more fun.


O'Neill will stick with Northern Ireland if they make Euro play-offs
by BeSoccerNorthern Ireland manager Michael O'Neill plans to remain in charge should his country reach the Euro 2020 qualifying play-offs despite his impending move to Stoke.
Northern Ireland host the Netherlands in what could be O'Neill's final match in charge at Windsor Park on Saturday after he was announced as Stoke's new boss last week.
With Stoke battling to climb away from the Championship relegation zone, it has been suggested O'Neill would leave regardless of whether Northern Ireland reach the play-offs.
But on Friday he said he will remain in charge of Northern Ireland until the end of their Euro 2020 qualifying campaign, whether that ends in the next seven days or extends into March.
Asked if he was committed to staying for the rest of the campaign, O'Neill said: "That's the plan at the minute."
Northern Ireland face the Netherlands this weekend and Germany in Frankfurt on Tuesday in their final Group C fixtures, knowing automatic qualification is highly unlikely.
They are however currently well placed for the play-offs.

Insisting the Stoke job hasn't been a distraction, O'Neill said: "The week has been no different from any other week. We've got the work done. The players have been very focused, maybe more so because they're thinking, as a club manager I might sign them."
Northern Ireland can take encouragement from their performance in Rotterdam, where Holland needed two stoppage-time goals to complete a come-from-behind 3-1 win last month.
But, regardless of the result in Belfast, O'Neill isn't thinking about a fond farewell just yet.
"I haven't thought about it to be honest. I'm not one for big emotion," he said.
"I'll just try and prepare the team as well as we can. The main thing is to try and get a result and take it to the last game.
"Maybe I'm young enough to come back in the future!"


Muppy tries to help developers to identity memory leaks of Python applications. It enables the tracking of memory usage during runtime and the identification of objects which are leaking. Additionally, tools are provided which allow to locate the source of not released objects.
Muppy is (yet another) Memory Usage Profiler for Python. The focus of this toolset is laid on the identification of memory leaks. Let’s have a look what you can do with muppy.
Muppy allows you to get hold of all objects,
>>> from pympler import muppy
>>> all_objects = muppy.get_objects()
>>> len(all_objects)
19700
or filter out certain types of objects.
>>> import types
>>> types = muppy.filter(all_objects, Type=types.ClassType)
>>> len(types)
72
>>> for t in types:
... print t
...

. . .
This result, for example, tells us that the number of lists remained the same, but the memory allocated by lists has increased by 8 bytes. The correct increase for a LP64 system (see 64-Bit_Programming_Models).
You can create summaries
>>> from pympler import summary
>>> sum1 = summary.summarize(all_objects)
>>> summary.print_(sum1)
types | # objects | total size
============================ | =========== | ============
dict | 546 | 953.30 KB

and compare them with other summaries.
>>> sum2 = summary.summarize(muppy.get_objects())
>>> diff = summary.get_diff(sum1, sum2)
>>> summary.print_(diff)
types | # objects | total size

frame (codename: <module>) | 1 | 424 B
classmethod_descriptor | 3 | 216 B
code | 1 | 120 B
Of course we don’t have to do all these steps manually, instead we can use muppy’s tracker.
>>> from pympler import tracker
>>> tr = tracker.SummaryTracker()
>>> tr.print_diff()
types | # objects | total size
====================================== | =========== | ============
list | 1095 | 160.78 KB

frame (codename: print_diff) | 1 | 480 B
frame (codename: diff) | 1 | 464 B
function (store_info) | 1 | 120 B
cell | 2 | 112 B
A tracker object creates a summary (that is a summary which it will remember) on initialization. Now whenever you call tracker.print_diff(), a new summary of the current state is created, compared to the previous summary and printed to the console. As you can see here, quite a few objects got in between these two invocations. But if you don’t do anything, nothing will change.
>>> tr.print_diff()
types | # objects | total size
======= | =========== | ============
Now check out this code snippet
>>> i = 1
>>> l = [1,2,3,4]
>>> d = {}
>>> tr.print_diff()
types | # objects | total size
======= | =========== | ============
dict | 1 | 280 B
list | 1 | 192 B
As you can see both, the new list and the new dict appear in the summary, but not the 4 integers used. Why is that? Because they existed already before they were used here, that is some other part in the Python interpreter code makes already use of them. Thus, they are not new.
In case some objects are leaking and you don’t know where they are still referenced, you can use the referrers browser. At first let’s create a root object which we then reference from a tuple and a list.
>>> from pympler import refbrowser
>>> root = "some root object"
>>> root_ref1 = [root]
>>> root_ref2 = (root, )
>>> def output_function(o):
... return str(type(o))
...
>>> cb = refbrowser.ConsoleBrowser(root, maxdepth=2, str_func=output_function)
Then we create a ConsoleBrowser, which will give us a referrers tree starting at root, printing to a maximum depth of 2, and uses str_func to represent objects. Now it’s time to see where we are at.
>>> cb.print_tree()
<type 'str'>-+-<type 'dict'>-+-<type 'list'>
| +-<type 'list'>
| +-<type 'list'>
|
+-<type 'dict'>-+-<type 'module'>
| +-<type 'list'>
| +-<type 'frame'>
| +-<type 'function'>
| +-<type 'list'>
| +-<type 'frame'>
| +-<type 'list'>
| +-<type 'function'>
| +-<type 'frame'>
|
+-<type 'list'>--<type 'dict'>
+-<type 'tuple'>--<type 'dict'>
+-<type 'dict'>--<class 'muppy.refbrowser.ConsoleBrowser'>
What we see is that the root object is referenced by the tuple and the list, as well as by three dictionaries. These dictionaries belong to the environment, e.g. the ConsoleBrowser we just started and the current execution context.
This console browsing is of course kind of inconvenient. Much better would be an InteractiveBrowser. Let’s see what we got.
>>> from pympler import refbrowser
>>> ib = refbrowser.InteractiveBrowser(root)
>>> ib.main()
Now you can click through all referrers of the root object.


Since this index page will be primarily used as basically a table of contents for various pages and blog posts we have worked on, I decided I want to make it look more visually pleasing and fun by integrating pictures in an instagram-like way. I plan to stagger the images and put content to the right and left of them. This content will be separated out into lists of links since they will basically fit into categories. As we create more pages and categories of pages over this course, I can expand horizontally or vertically with the sections. I will make the sections a percentage width of their container and will set a max width on the container so the images do not get huge.
I want to be consistent across all of my pages so I will be using the same fonts and colors as I have used for my blog pages and a similar structure.

cPointArray defines an array of points, each composed of a single vertex.
A point array is created by first passing a reference to an array of vertices (cVertexArray) from which the points are composed.
For graphic rendering purposes and memory efficiency, points are stored in large arrays. The number of allocated points in an array can be retrieved by calling getNumElements().
New points can be added or removed by calling newPoint() and removePoint(). respectively.
When a point is removed from the array, its vertex index is set to zero and the point index number is added to a list of free points for future allocation.
To avoid accumulating large numbers of free points, it is possible to compress the array by calling compress(). This method removes all non used points from memory.

This method compress the point array by removing all non allocated points. If many points are unused, this method can effectively reduce the memory footprint allocated by the array.
IMPORTANT:
After calling this method, it is important to immediately update any collision detector as the collision tree may try to access points that no longer exist.
|
inline |
This method creates a new point.
| a_vertexIndex0 | index of vertex 0. |
|
inline |
This method deallocates a selected point from the array. Its vertex index is set to zero, and the point is added to the free list for future allocation.
| a_pointIndex | Index number of selected point. |
|
inline |
This method sets the vertex of a selected point by passing its index number.
| a_pointIndex | Index of selected point. |
| a_vertexIndex | Index of vertex. |
|
inline |
This method returns the index number of the vertex that describes a selected point.
| a_pointIndex | Index of point. |
|
inlinevirtual |
This method reads the index number of the vertex of a selected point. In the case of a point a_vertexNumber
only takes value 0, as a point is only composed of a single vertex.
| a_elementIndex | Index number of selected point. |
| a_vertexNumber | Vertex number. |
Reimplemented from chai3d::cGenericArray.
|
inline |
This method returns the texture coordinate at the point. For points, a_localPos is meaningless and ignore. This value is used however for segments or triangles.
| a_pointIndex | Index number of selected point. |
| a_localPos | Value ignored. |
|
inlinevirtual |
This method renders the OpenGL vertex buffer object.
Reimplemented from chai3d::cGenericArray.
|
virtual |
This method checks if the given line point intersects a selected a point from this array.
If a collision occurs, the collision point is reported to the collision recorder.
| a_elementIndex | Point index number. |
| a_object | Pointer to the object on which collision detection is being performed. |
| a_segmentPointA | Point from where collision ray starts (in local frame). |
| a_segmentPointB | Direction vector of collision ray (in local frame). |
| a_recorder | Stores collision events. |
| a_settings | Collision detection settings. |
Reimplemented from chai3d::cGenericArray.

The RFEF are not contemplating calling up Barça's Pique for Olympics
The defender had left the door open when asked if he would like to play in Japan
by Ramon FuentesGerard Pique suggested in an interview with Cadena Ser this week that he would be open to playing for Spain at the Olympic Games next summer.
However, sources inside the Spanish Football Federation (RFEF) have told SPORT they took the Barcelona defender's "missive" as more of a joke than anything else.
Pique does have a good relationship with RFEF president Luis Rubiales but that is unlikely to be enough to see him called up for the Olympics in Japan next summer, keeping in mind he's retired from international football.
But Real Madrid's Sergio Ramos could go, occupying one of the three places in the squad reserved for players over the age of 23.
