Since HexEdit 4.0 there have been many new features. A few of these also appeared in HexEdit Pro 4.0, but most are completely new. (The shareware program HexEdit Pro has been discontinued and all of its features were incorporated into HexEdit 5.0.)
There are some major new features, several medium-level additions and lots of small level improvements and bug fixes.
major features are the new file compare view and bitmap preview
the character area now has comprehensive support for Windows code pages
other features are background processing (CRC/digests) + Windows 7 TaskBar support
there are also new operations for CRCs, encoding (Base64 etc) and digests (SHA etc)
many other new commands and options were added as well as improvements to existing features
long operations now show progress in the HexEdit Task Bar Icon
hovering the mouse over the HexEdit icon shows a thumb nail of files currently open
recently opened files are added to the Task Bar "Recently Used" list
commonly opened files are added to the Task Bar "Most Used" list
files in the HexEdit "Favorites" category are added to the Task Bar "Favorites" list
new File Folders page gives many options for where the File Open/Save dialogs start
new Background processing adds many new options on top of background searching
new Explorer page adds options related to Explorer window (wipe strategy etc)
new Aerial View page allows you to set the maximum bitmap size used
new document settings for Preview and Compare views (see below)
new Code Page selection as well as invalid/continuation display character
ability to select all three character area fonts (normal/OEM/multi-byte fonts)
several new options in addition to background searches (which HexEdit has always had)
all background processing is done in low-priority background threads
ability to count the occurrences of all 256 bytes values (for display in properties dialog graph)
calculate SHA and SHA-2 digests and CRC32 on the whole file
ability to turn off background processing for
some types of files (network, removeable media, etc)
this can avoid problems like excessive network traffic,
display pauses, etc
fixed flicker of selection count
use the new Search button to quickly find a file by keyword/category/etc
Open Read Only checkbox
Open Shareable checkbox
integer calculations now support any precisionincluding Infinite
digest and CRC results are dumped into calculator for easy use in macros
easy selection of any radix from 2 to 36
easy selection of any number of bits 1 to Infinite
select signed or unsigned
display of current expression above text entry box
select previously entered expression to re-evaluate using drop-list
see complete history of calculations using Calculator Tape window
Floating point page: now supports Real48 (as in Delphi, Turbo Pascal)
Time page: now supports most common time64_t (C/C++) format
new Counts page: graph of byte counts (see Background Processing)
new Stats page: CRC32, MD5, SHA, SHA-2 of whole file (Background Processing)
custom context menu when a file is right-clicked
quickly set a file time based on a DATE var (or now)
quickly set all file times (created/modified/accessed)
quickly set/clear common file flags (read-only etc)

display in split or tabbed window
modify bitmap in memory and instantly see the effects
complete control of zoom/pan using menus or mouse
full display for transparency (alpha channel)
4 different backgrounds for viewing transparency
checkerboard background allows better view of partial transparency
new Bitmap Properties page shows bitmap info (on disk + in memory)
compare with a different disk file
other file view is shown in split or tabbed window
synchronous scrolling of both views
synchronize selection between both views
copy to clipboard in compare window
Compare List tool window lists all differences
menu/keyboard commands to move through differences
Option to find insertions/deletions
Option to compare a file with itself to see changes over time
uses SSE2 (SIMD) instructions for huge performance boost
The Wix installer is no longer used - we now use InstallAware
HexEdit uses the Boost library for many things - of particular recent note is CRCs
Crypto++ is now also used - for digests (MD5, SHA, etc) and encoding (Base64 etc)
Infiinite precision integers (as used in the calculator) are now handled by MPIR library
SVN is no longer used for version control - we now use Git
HexEdit source is no longer hosted by SourceForge, instead by GitHub
Visual Studio 2010 or later is required as HexEdit
now uses SSE2 intrinsics
for greatly improved performance (eg, NOT operation and file compare)


Elisa’s 5G network powered by Nokia is super fast
by MarinNokia is empowering the 5G network of Finland’s operator Elisa. Harri Holma from Nokia just demonstrated how great the download speeds over Elisa’s 5G network will be in the city of Espoo, Finland. The maximum speed achieved was greater than 1.14 Gbps, which is crazy when compared to the speeds we currently have with 4G networks. One gigabyte can be downloaded in just 10 seconds, and that sounds great. Nokia’s engineers did a good job.
The speed probably won’t be that high when we all transfer to 5G smartphones, but 300 Mbps and higher would be great. The demo was probably done on ZTE Axon 10 Pro 5G since Elisa is currently offering that device together with Huawei Mate 20 X 5G and
OnePlus 7 Pro 5G. Hopefully, we’ll be seeing a 5G Nokia device listed on their web page dedicated to 5G devices and interfaces.

Introduction
The Standard ML of New Jersey Library (SML/NJ Library) is a collection of over 200 modules grouped into 14 libraries. It was designed to build on the Standard ML Basis Library by providing higher-level and application-specific services that were out of scope for the Basis Library. The SML/NJ Library is distributed as part of both the SML/NJ and MLton SML Compiler systems.


Make sure that you have the jQuery and hoverFlow JavaScript files included in your document like so:
<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript" src="jquery.hoverflow.js"></script>
Also make sure that the jQuery
-method is called when the DOM is ready, either by putting your scripts at the bottom of the document or by using the document.ready() hook:
$(document).ready(function() {
// put your code here
});
Typically, you use the hoverFlow()
-method within a hover event binding as you would use jQuery's own animate()
-method. Both take the same arguments, except that the hoverFlow()
-method additionally needs to have the event type as its first argument.
$('.demo1 .anim_queue_example a')
.hover(function(e) {
$(this).hoverFlow(e.type, { left: 20 }, 'fast');
}, function(e) {
$(this).hoverFlow(e.type, { left: 0 }, 'fast');
});
It's easy to get the event type since jQuery passes the whole event object to the bound function. You only have to define an alias in the function definition (called e
in the code above) and than get e.type
. Having that in mind, the following code does exact the same as the code above, but without using the event object:
$('.demo1 .anim_queue_example a')
.hover(function() {
$(this).hoverFlow('mouseenter', { left: 20 }, 'fast');
}, function() {
$(this).hoverFlow('mouseleave', { left: 0 }, 'fast');
});
It's not required to use hoverFlow()
inside a hover event binding. The plugin accepts the follwing event types: mouseover, mouseout, mouseenter, mouseleave (with jQuery's hover()
function using mouseenter/-leave internally).
$('.demo2 .anim_queue_example a')
.bind('mouseover', function(e) {
$(this).hoverFlow(e.type, { left: 20 }, 'fast');
}).bind('mouseout', function(e) {
$(this).hoverFlow(e.type, { left: 0 }, 'fast');
});
jQuery has two different interfaces for its animate()
-method: animate(params, duration, easing, callback)
and animate(params, options)
The hoverFlow plugin accepts both versions, so that you can easily use it as a replacement for your animate()
calls. In both cases, however, the hoverFlow()
-method expects the event type as its first parameter.
$('.demo3 .anim_queue_example a')
.hover(function(e) {
$(this).hoverFlow(e.type, { left: 20 }, {
duration: 600,
complete: function() {
var $this =$(this);
var count = parseInt($this.text(), 10);
$this.text(isNaN(count) ? 1 : (count + 1));
}});
}, function(e) {
$(this).hoverFlow(e.type, { left: 0 }, 'fast');
});
There is one limitation when using the options hash: You cannot set the queue value to true (since the plugin requires this value to be false).
Like (almost) every other jQuery method, the hoverFlow
-method is completely chainable.
$('.demo4 .anim_queue_example a')
.hover(function(e) {
$(this).hoverFlow(e.type, { left: 20 }, 'fast').css('backgroundColor', '#99CCFF');
}, function(e) {
$(this).hoverFlow(e.type, { left: 0 }, 'fast').css('backgroundColor', '#000');
});
The hoverFlow plugin also works with live() event binding as introduced in jQuery 1.3. However, as of jQuery 1.3.2, the mouseenter and mouseleave events are not supported yet with live().
$('.demo5 .anim_queue_example a')
.live('mouseover', function(e) {
$(this).hoverFlow(e.type, { left: 20 }, 'fast');
}).live('mouseout', function(e) {
$(this).hoverFlow(e.type, { left: 0 }, 'fast');
});

[gecode-users] Runtime problem

Hi,
First of all, you should really use the new version, Gecode 2.2.0 has
several important bug-fixes.
Secondly, I'm not sure if you are experiencing troubles with
memory-consumption, since the error-log indicates that you have around
90 Mb of free memory. Unfortunately I have no direct ideas as to what
the bug is - the log-file only says that the error is in
GecodeSearch.dll. Is it possible to reduce the example to something
smaller, or to run it under a debug-build of Gecode?
Cheers,
Mikael

iVXjs Templates Tutorial
Overview
As a developer, you may want to utilize templates for adding HTML to elements such as state headers/footers and labels. To do this, you can add data that is a path to the .html file where you template is.
Demo
HTML State Templates
Overview
As a developer, you will probably be using templates mostly in HTML states. These states can have a very long and cumbersome HTML strings since this state acts more or less like a static web page. This will show you how to add templatesUrls into HTML states.
Sample Data
For this section of the tutorial, we will be using html-state-sample.json file.
From JSON: HTML State’s HTML
Let’s first review how the HTML state renders HTML without a template:
- HTML State’s Data From JSON file:
{
"id": "html-state-sample",
"name": "HTML State Sample",
"url": "/html-state-sample",
"type": "html",
"html" : "
Sample HTML State

Will time out in 5 seconds
",
"onEnter": [],
"onExit": [],
"onTimeout" : [],
"timeoutInMs": 5000,
"next": [{
"stateId" : "html-state-sample-2"
}]
}
- Add change the HTML to
"
HTML State

This came from the JSON
"
to thehtml
:
{
...
html : "
HTML State

This came from the JSON
"
...
}
- After adding the HTML it should look like this:
From Template: HTML State’s HTML
Even though adding HTML from the JSON does work, it could bloat the JSON spec if we had to add any other elements to the HTML and on top of that. It could cause JSON lint errors if we aren’t careful about escaping characters when writing it.
So, let’s move the value of html
in the spec to its own template.
- Move the value of
html
to a file called html-state.html :
html-state.html

HTML State

This came from the JSON.

- Change the

element to read “This came from a template.”:
html-state.html

HTML State

This came from a template.

- Remove the
html
data from the HTML State Data:
{
"id": "html-state-test",
"name": "HTML State Test",
"url": "/html-state-test",
"type": "html",
"onEnter": [],
"onExit": [],
"next": [
]
}
- Add a new key
templateUrl
whose value is “html-state.html”:
{
"id": "html-state-test",
"name": "HTML State Test",
"url": "/html-state-test",
"type": "html",
"templateUrl" : "html-state.html",
"onEnter": [],
"onExit": [],
"next": [
]
}
- Refresh the page, and you should see a screen similar to this one:
Header/Footer Templates
Overview
Any state that has a header/footer data object can use templates for their HTML. This will help a developer be able to add intricate headers and footers without bloating the JSON spec.
Sample Data
For this tutorial we will be using the video-state-sample.json file.
From JSON: Adding HTML to Headers/Footers
To add custom HTML to the Headers/Footers from JSON do the following:
- Here is the sample Video State Data:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [],
"cuePoints": []
}
- Add the key
"html"
with value"
I AM FROM THE JSON
"
to either the header or footer object:
{
...
"header" : {
"html" : "
I AM FROM THE JSON
"
},
...
}
- The resulting data will look like this:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {
"html" : "
I AM FROM THE JSON
",
"classes": ""
},
"footer": {
"html": ""
},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [],
"cuePoints": []
}
- This will render something like this:
From Template: Adding HTML to Headers/Footers
To add custom HTML to the headers/footers from a template, we will modify the above data as follows:
- Here is the video state data from above:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {
"html": "",
"classes": ""
},
"footer": {
"html": ""
},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [],
"cuePoints": []
}
- Take the HTML from the header’s
"html"
value and add it to a file called ‘video-header.html’ and replace the text to read “I AM FROM A TEMPLATE!”:
video-header.html

I AM FROM A TEMPLATE!

- Replace the header’s
"html"
with the key"templateUrl"
whose value is"video-header.html"
:
{
...
"header" : {
"templateUrl" : "video-header.html"
},
...
}
- The resulting video state data will look like this:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {
"templateUrl" : "video-header.html",
"classes": ""
},
"footer": {
"html": ""
},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [],
"cuePoints": []
}
- Refresh the page, and it should look something like this:
Video Personalizations Templates
Overview
As a developer, some video personalizations–segments of HTML to appear/disappear as a user watches a video– will require a template to be able to render and behave correctly.
Sample Data
For this tutorial we will be using the video-state-sample.json file.
Special note about personalizations:
Personalizations, which typically show and hide and a cuepoint, requires some CSS to allow this behavior. In this tutorial, the state will add the class “hide” and on the cuepoint will add the class “show”. If you don’t have any CSS to support these behaviors, this will not work. To support these, you can add this HTML:

From JSON: Adding HTML To Personalizations
To add custom HTML to a personalization, do the following:
- Here is the base state data from the sample:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [],
"cuePoints": []
}
- Add a personalization by adding an object to the personalizations array with keys
"id"
which is the id of personalization and"html"
which is the HTML for the personalization:
{
...
"personalizations": [{
"id" : "personalization",
"html" : "
I am from the JSON.
"
}],
...
}
- Add a cuePoint data object the event “animateElement” at 2 seconds which will show your personalization:
{
...
"cuePoints": [{
"eventName" : "animateElement",
"timeAt" : 2,
"args" : {
"element" : "#personalization",
"animationClasses" : "show"
}
}]
...
}
- The resulting state data will look like this:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [{
"id": "personalization",
"html": "
I am from the JSON.
"
}],
"cuePoints": [{
"eventName": "animateElement",
"timeAt": 2,
"args": {
"element": "#personalization",
"animationClasses": "show"
}
}]
}
- Once you add this data, play the video and after 2 seconds, you should see something like this:
From Template: Using Templates For Personalizations
Let’s now use templates for personalizations.
- Here is the current state data from the above tutorial:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [{
"id": "personalization",
"html": "
I am from the JSON.
"
}],
"cuePoints": [{
"eventName": "animateElement",
"timeAt": 2,
"args": {
"element": "#personalization",
"animationClasses": "show"
}
}]
}
- To begin, move the value of the “html” from the personalization with id “personalization” and add it to a file called “video-personalization.html” and change the text to read “I am a personalization from a template.”:
video-personalization.html

I am a personalization from a template.

- Replace the
"html"
in the personalization with the key"templateUrl"
with value"video-personalization.html"
:
{
...
"personalizations" : [{
"id" : "personalization",
"templateUrl" : "video-personalization.html"
}]
...
}
- The resulting state data will be:
{
"id": "html5-video-state-test",
"name": "HTML5 Video Test",
"url": "/html5-video-test",
"type": "video",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"next": [],
"onVideoEnd": [],
"playerSettings": {
"controls": "standard",
"sources": [{
"src": "http://clips.vorwaerts-gmbh.de/VfE_html5.mp4",
"type": "video/mp4"
}]
},
"personalizations": [{
"id": "personalization",
"templateUrl" : "video-personalization.html"
}],
"cuePoints": [{
"eventName": "animateElement",
"timeAt": 2,
"args": {
"element": "#personalization",
"animationClasses": "show"
}
}]
}
- Now play the video, and after 2 seconds, the player should look something like this:
Label Templates
Anywhere in the JSON spec where there is either a "label"
or "labelHTML"
, you can add a template.
Sample Data for Label Template Tutorial
For this tutorial we will be using the input-state-sample.json file.
From JSON: Adding Label HTML
- Here is the original input state data from the sample file:
{
"id": "input-state-test",
"name": "Input State Test",
"url": "/input-state-test",
"type": "input",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"onSubmit": [],
"form": {
"classes": "",
"submit": {}
},
"next": [],
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"label": "I am a label",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
}
- Find the input object with
"id"
value of"text-input-test"
in the inputs array:
{
...
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"label": "I am a label",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
...
}
...
{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"label": "I am a label",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}
...
- To add the custom html, replace
"label"
with"labelHTML"
and its value to"
I am from the JSON
"
in this input:
[
...
{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelHTML": "
I am from the JSON
",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}
...
]
- The resulting input state data should look like this:
{
"id": "input-state-test",
"name": "Input State Test",
"url": "/input-state-test",
"type": "input",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"onSubmit": [],
"form": {
"classes": "",
"submit": {}
},
"next": [],
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelHTML": "
I am from the JSON
",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
}
- This should render like this:
From Template: Adding HTML to Labels from Templates
Let’s now add html from a template html file for a label.
- Here is the resulting data from above:
{
"id": "input-state-test",
"name": "Input State Test",
"url": "/input-state-test",
"type": "input",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"onSubmit": [],
"form": {
"classes": "",
"submit": {}
},
"next": [],
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelHTML": "
I am from the JSON
",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
}
- Again find the input data object in the
"inputs"
array with"id"
equal to"text-input-test"
:
{
...
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelHTML": "
I am from the JSON
",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
...
}
[
...
{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelHTML": "
I am from the JSON
",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}
...
]
- Take the value of
"labelHTML"
and add it to a file called “input-label.html” and replace the value “I am from the JSON” with the value “I am from the template”:
input-label.html

I am from the template

- Now reaplce
"labelHTML"
with the key"labelTemplateUrl"
whose value is ` “input-label.html”`:
[
...
{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelTemplateUrl": "input-label.html",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}
...
]
- The resulting data should look like this:
{
"id": "input-state-test",
"name": "Input State Test",
"url": "/input-state-test",
"type": "input",
"header": {},
"footer": {},
"onEnter": [],
"onExit": [],
"onSubmit": [],
"form": {
"classes": "",
"submit": {}
},
"next": [],
"inputs": [{
"id": "text-input-test",
"name": "textInputTest",
"type": "text",
"labelTemplateUrl": "input-label.html",
"settings": {
"container": {},
"input": {}
},
"attributes": {}
}]
}
- This should render into something like this:
Things to Look Out For
Template Limitations
Due to what rendering library you are using in conjunction with iVX.js, your templates may not be universal. For example, for the Angular Distribution, the library uses the ngInclude directive and you can replace elements in your file using handles bars –``. However, this may not work with other frameworks.
Template URL Override
If, as a developer, you add the data key to add a template, this will always have a higher level of presedence over other data that adds HTML. For example, if as a developer you wrote your Header data object like this:
{
...
"header" : {
"html" : "
I WILL NOT BE SEEN
",
"templateUrl" : "templates/test.html"
}
...
}
The
I WILL NOT BE SEEN

will not be seen.

- Change the Visual Studio project type:
- Unload the project with tests.
- Remove <ProjectTypeGuids> node from there.
- Save and reload the project.
- Replace Reference from MsTest to your xUnit.
- Replace using statements (Remove Microsoft.VisualStudio.TestTools.UnitTesting, add NUnit.Framework and optionally NUnit.Framework.SyntaxHelpers).
- Replace (just use Find and Replace in Files) [TestClass] to [TestFixture].
- Replace [TestMethod] to [Test].
- Replace [TestInitialize] to [SetUp].
- Replace [TestCleanup] to [TearDown]
- Now you should be able to compile the tests.
- Clean all the stuff from MsTest (TestResults folder, Solution Items that describe test data).
The note is (if you don’t know) that there’s no build-in runner for Visual Studio (unlike MsTes), so you’ll need to run tests:
- from outside of Visual Studio by GUI runner
- using TestDriven.NET
- using ReSharper.


The DOM of a Web page is organized as a tree structure. The elements in the page have family-like names to refer to their positions relative to other elements.
For example, the HEAD and BODY tags are "children" of the HTML tag, and are "siblings" of each other. They have the HTML tag as their "parent". jQuery provides functions for navigating the document tree and processing sets of elements, such as:
children()
: Retrieves all the child elements of the matched elements, except text nodesprev(), next(), parent()
: used to traverse the family relationships of an elementfind()
: search within a given element to find elements that match a selector expressioneach()
: loops over a set of matched elements and calls a function for each one

Decision on NCP, TMC, CPI national status likely next year
The Election Commission of India is likely to take a call on whether the Nationalist Congress Party, the All-India Trinamool Congress and the Communist Party of India can continue to have the status of national parties only after the next round of Assembly elections that are expected to finish early next year, ECI officials said on Wednesday.
The ECI has been hearing the issue of de-recognition of the three parties after their performance in the Lok Sabha elections.
A party’s candidates have to secure at least 6% vote share in four States or more and it must have at least four Lok Sabha MPs for the status.
An ECI official said the parties had asked for more time since Assembly elections in Jharkhand, scheduled to finish in December, and Delhi, expected to go to polls in early 2020, were coming up. The official said the ECI had not passed any orders yet and might decide after the elections, having accepted the parties’ request for time.

Motivation¶
In recent years, Artificial Intelligence and, more specifically, Machine Learning, has become remarkably good at performing human-level tasks: recognizing objects and faces in images, driving cars, and playing sophisticated games like chess and Go.
In order to achieve these incredible levels of performance, current approaches leverage vast amounts of data to learn underlying patterns and features. Thus, state-of-the-art Machine Learning models leverage significant amounts of computing power, training on advanced processors for weeks or months, consequently consuming enormous amounts of energy. Depending on the energy grid used during this process, this can entail the emission of large amounts of greenhouse gases such as CO₂
With AI models becoming more ubiquitous and deployed across different sectors and industries, AI’s environmental impact is also growing. This is why it is important to estimate and curtail both the energy used and the emissions produced by training and deploying AI models. This package enables developers to track carbon dioxide (CO₂) emissions across machine learning experiments or other programs.
This package enables developers to track emissions, measured as kilograms of CO₂-equivalents, or CO₂eq, in order to estimate the carbon footprint of their work. In order to do this, we use CO₂-equivalents [CO₂eq]
, which is a standardized measure used to express the global warming potential of various greenhouse gases: the amount of CO₂ that would have the equivalent global warming impact. For computing, which emits CO₂ via the electricity it is consuming, which is generated as part of the broader electrical grid – for example, electricity generated by combusting by fossil fuels such as coal – carbon emissions are measured in kilograms of CO₂-equivalent per kilowatt-hour.

Chiredzi plunged into mourning
by Staff ReporterChiredzi Town is in mourning after residents lost six of their own in a head-on collision involving a commuter omnibus and a haulage truck at Maranda turn off at the 166km peg along the Masvingo-Beitbridge highway yesterday.
Police national spokesperson Assistant Commissioner Paul Nyathi said the six are Messrs Reuben Madzingo (24), Tawonga Mazana (28), Farai (38) and Collen Ernest Chipungu (37), Delight Zireva (31) and Vimbai Beta (41).
Mr Beta was a farm manager at Farmware in Chiredzi.
Information gathered by The Herald shows that five of the six were business people involved in commodity broking and were travelling to Polokwane in South Africa on a routine business trip while Madzingo had been sent by his father to purchase spare parts for their tractor.
The vehicle they were travelling in was being driven by the owner Collen and they left Chiredzi around 3am. Zireva was a newlywed after tying the knot in April last year and he left a wife who is expecting.  Madzingo was a former student of the School of Mines, who was waiting for his final examinations results while Mazana was still cutting his teeth in business.
Mr Reuben Madzingo (snr) told The Herald today that he was still devastated and in shock.
“Reuben is my son and he has just completed his final examinations at the School of Mines,” he said.
“One of my tractors has not been operational and I had sent him to procure some spare parts in South Africa. I am the one who called his colleagues to come and pick him up on their way to South Africa and they left Chiredzi around 3am. I then tried to call Reuben around 8am and his mobile phone was no longer reachable. I tried to call the people in South Africa where he was supposed to buy the spare parts and they said he had not yet arrived.”

“On ships, attempts to melt the ice by buckets of hot water or by steam jets are only partially effective, because a great deal of heat is needed to melt a little ice. Further, if the temperature is still below freezing point when the operation is being carried out, the melted ice may freeze again unless it can be pushed overboard first. Mechanical detachment of the ice is no easy matter, for ice adheres most tenaciously to clean, grease-free surfaces and a ship has often been thoroughly de-greased by wind-swept rain and spray before it becomes iced-up.” — G Van Praagh, De-Icing Of Ships

Ross: Well, yeah, kinda. Um, but thats okay, see we have an understanding, um, see we each have this list of five famous people, (gets his out) so Im allowed to sleep with you. No, no, no, its flattery.

Ross: Um, see, but thats not the final draft.
Isabella: Its laminated!
Ross: Yeah, um, okay see, you were, you were on the list but my friend, Chandler (Chandler waves) brought up the very good point that you are international, so I bumped you for Wynona Rider, local.
Isabella: Y'know its ironic...
Ross: What?
Isabella: ...because I have a list of five goofy coffee house guys and yesterday I bumped you for that guy over there. (points at a guy and leaves)
Ross: (to the rest of the gang) Were just gonna be friends.

I started reading about this topic when looking for a computationally cheap way of doing frequency shifting. This is distinct from pitch shifting:
Pitch shifting is a more familiar effect. It moves the energy at all frequencies a proportional amount up or down. With pitch shifting the relative distance between each frequency is preserved. If you imagine a graphed frequency spectrum, with the horizontal axis laid out logarithmically in Hz, a pitch shifting spectrum will hold it’s shape as is moves back or forth along the Hz axis. The auditory result is to preserve the timbre while changing the “note”.
Frequency shifting, however, shifts each frequency in a signal by a set number of Hz. Since we don’t perceive pitch linearly, this has a bizarre effect on the signal, totally transforming the timbre.
You could take a Fourier transform of the signal, apply the transformation to the spectrum, then re-synthesize the signal to get the result. However, this is computationally expensive and restrictive. Lucky, it turns out you can get a pretty good frequency shifting by exploiting the properties of ring modulation. We’ll get to this in a bit. First let’s think about some concepts. Humour me, there is a point to it all…
When we think about basic mathematical operations (addition, subtraction, multiplication, division), our instincts are based in experience of the natural world, apply mainly to the natural numbers. For example, when we are counting apples, we expect addition and multiplication to be operations that increase our number of apples, while subtraction and division are going to be decreasers. Obviously we know about the existence of negative numbers, fractions, and so on. Nonetheless, our instincts about these operations can occasionally be misleading when thinking about signals.
Clearly signals are not apples. They’re more like boxes containing both apples and anti-apples. So it’s worth taking a moment to rethink the basic operations.
Thinking about the boxes of apples and anti-apples, subtraction and addition are not really looking so opposite any more, in fact they are pretty similar in some senses. Say you have two signals: A = 440 hz sine wave and B = 100 hz sine wave. The outcome of adding B to A will be a signal with two frequencies (440 hz, 100 hz). The outcome of subtracting B from A will also be a signal with two frequencies. Sure, B will be inversed, but the auditory result is pretty similar to the addition.
Rather than thinking of multiplication as an increaser, I like to visualise it as a test of similarity. It seems like a strange way to think of multiplication, but it is helpful. Say I want to test how similar some number A is to some number B. If B is identical to A then their product will be a perfect square of A. If B is the exact opposite to A then the product will be the negation of the perfect square of A. Likewise if B is similar bigger, or similar but smaller, and so on, we can see this in the product of the two numbers in relation a the square of A.
This sort of logic is most clear when thinking about the product of signed numbers:
Negative * Negative = Positive (think of it as tested positive for having a similar sign)
Negative * Positive = Negative (failed the test for sign similarity)
Positive * Negative = Negative (same as above)
Positive * Positive = Positive (similar sign. So positive similarity)
So, how about we multiply some signals together? This is effectively ring modulation. Ring modulation gets its name from the circular arrangement of diodes in its analog implementation (I understand nothing about electronics).
The result of ring modulating two signals is the sum and difference pair of each frequency across the two signals. For example, multiplying a 100 hz sine with a 440 hz sine will result in a signal with frequencies of 540 hz and 340 hz.
Okay, two thoughts. Firstly: Great! The sum component of the result looks like it will be very useful for our frequency shifter. Secondly: Why does it behave like this?
I think we can develop an instinct for why this happens. Before we start multiplying, first imagine summing two identical functions together. Let’s imagine it with cos(x) for simplicity:
Since our two functions line up perfectly, we’ve just doubled the amplitude.
How about if they are not exactly the same? If you’ve ever heard two notes of very similar but not identical pitches played at the same time you’ll be familiar with the “beating” effect this creates. When they are both contributing the same sign the sound is louder, then they slip out of sync and it dips down. This all happens quite quickly and repetitively, causing the beating. Here are two non-identical sine waves added together:
You can see the “beating” effect visually here.
Okay, now on to multiplication. What happens if we multiply a signal by itself? Well, we know that like negative * negative = positive, and positive * positive = positive, so all the overlapping negative bits are going to become positive bits. So we’ll double the frequency and shift everything up above the horizontal axis, like so:
Notice. We got the sum frequency sin(12x). The difference is zero.
Great. How about if we multiply two signals that are not identical? Let’s have a look:
Look carefully and you’ll see that whenever ether of the input signals approaches 0 it pulls the resulting output towards 0. When the two input signals closely match each other, the output is a high, positive value. When they are very dissimilar the output is a high negative value. As discussed above, think of multiplication as a test of similarity.
Let’s see if we can reproduce the same signal with addition. If we take the sum and the difference of the signals above…
Pretty similar, you can see the same frequencies at work there. However if we scale it down by a half they look very similar indeed:
| $$y = \cos(4x) * \cos(6x)$$ | $$y = [\cos(10x) + \cos(2x) ] \frac{1}{2}$$ |
So, nothing formally proven here, but we can get a feel for why multiplication results in the sum and the difference of the input frequencies:
When multiplying two very similar sinusoids there will be a long expanse of relative similarity which gradually shifts into a long expanse of relative dissimilarity. That’s what is causing the “difference” part of the output, which is at a low frequency because the two inputs are close in frequency. If the inputs were very dissimilar frequencies, the “beating” of the “difference” becomes faster. The “sum” part is due to both input frequencies constantly pulling the output towards and away from 0 at their own speed.
We can see the concept from above taking place in these trig identities.
Considering these identities you can see why I chose to use cosines in the examples above, it’s the simplest version.
We’d like to be able to isolate the sums and differences in each of these. For these simple signals we can show how with a bit of rearrangement:
For example, take the first of the equations above:
We can isolate the term in the first equation like so:
That’s all well and good. However, usually the signals we are processing will not be simple sinusoids. The above shows that we can isolate that sum part of the ring modulation, but only in these situations. We need a general way to isolate the sum part of any signal that has been multiplied by a carrier signal in order to have a precise frequency shifter.
Here we shift gears and start looking at this all in the frequency domain.
Single-sideband modulation. This is the term used in communications signal processing for what we are trying to do here. We want to think of our carrier signal in the frequency domain as a single line representing that frequency, since it’s a sinusoid. Think of this as a center line. When we apply the carrier to our audio signal the outcome in the frequency domain will be distributed either side of that line. All the sum elements will shift above it, all the difference elements are subtracted away from it and are therefore flipped into the mirror image of the sum parts. These two sides of the output are called sidebands. We want to isolate the upper sideband.
From seeing this, your first instinct might be to use a high-pass to remove the lower sideband. This is an option, but it’s a sloppy one. We want something more exact.
If we go back to the trig stuff above, we found that:
We can generalise this to any real signal like so: Multiply audio signal by our carrier and then subtracting that to a copy of our audio signal that is phase shifted by - 90 degrees and then multiplied by the carrier but in phase quadrature, so .
The diagram above will create either the upper sideband or lower sideband depending on whether you add or subtract at the end.
Seems simple enough, but how to make that -90 degree phase shifted copy. We need to filter in some way to cause the phase shift. Conceptually, what we are after is a Hilbert Transform of our input signal.
The Hilbert Transform takes a time domain signal and returns a time domain signal with all of the positive frequencies shifted - 90 degrees and all of the negative frequencies + 90 degrees. The maths of the Hilbert transform is quite complicated in my opinion. We’re not going to dwell on it here for two reasons: it would be a tangential move from our topic, and more importantly because an ideal discrete time Hilbert filter is actually impossible to make. So we’ll be approximating it. We can do this with a network of all-pass filters.
All-pass filters affect the phase spectrum of a signal without changing the overall energy at each frequency. The result by itself is barely audible at all since all the same frequencies are retained, but each part of the spectrum is a tiny bit delayed relative to the frequency. Since they work by delaying the signal, they affect high frequencies most and low frequencies least. This isn’t ideal for us because we want to shift all frequencies evenly. The solution is to take our signal, split it into two and then use a whole bunch of all-passes on each one. Nether of the outputs will have a flat phase shift compared to the input, but they will be approximately 90 degrees phase from each other for a large part of the spectrum.
As for the layout of the all-pass network and the coefficients of the all-pass filters, it’s largely a matter of trial and error. Thankfully the work has been done for us already. Olli Niemitalo’s website provides one of the most efficient and simple arrangements floating around the web. Apparently the coefficients were found using a “genetic evolutionary algorithm”. Sounds nerdy as fudge… Anyhow it works great.
The all-pass network uses four all-pass filters per branch, and then delays one of them by one sample. In the diagram above the lower branch is the delayed one. Notice that we invert the lower branch, before adding it (same as subtracting it). This is because we want the upper, not the lower sideband. Go back to the trig section of this post to see why to see why
If you’ve taken all the info above, put it together and build a frequency shifter then well done! You may be annoyed to hear some nasty noises at the top end, especially when you push the carrier frequency high. This is aliasing. The problem is that the “sum” part of the multiplication is making frequencies that are beyond Nyquist frequency. Your options are either low pass filter the signal before it goes in (lame), or to up-sample both the input signal and carrier oscillator by a factor of 2, then do the multiplication, THEN low-pass to kill everything over Nyquist (much cooler). That way you preserve as much as possible.
Some weird concepts in this one. I spent a long time being concerned about the two sidebands overlapping, and how could you possibly isolate them if they were. Turns out they don’t, each frequency is added and subtracted from the carrier frequency, so they lie nicely either side of it.
Also, if you skimmed the trigonometry bit and then felt lost at the end then give it another pass. Once you see why the multiplication makes and sum and difference, and how either the sum or difference can be canceled out then the rest falls into place.
The Hilbert stuff. I feel kind of guilty for not writing more about it. It’s interesting and pretty challenging for me to wrap my head around. I spent a lot of time researching this article by learning about the analytic signal and Hilbert transform, then wrote practically nothing about it. The reason is i decided that it was too great a deviation from the objective of the article. It’s super interesting though. I recommend starting with this Wikipedia page.
Thanks for reading this. I hope it’s pulled together all the key information from various sources so you can use it all as you will. As ever, I welcome corrections from spelling to calling me out on having it all totally wrong!
