Bonfire Night 2019: Firework displays in West Dunbartonshire and Helensburgh
Details have been revealed of this year's events with Helensburgh's kicking off tomorrow night.
by Jenny Foulds, https://www.dailyrecord.co.uk/authors/jenny-foulds/Fireworks Night is set to go off with a bang this year with a number of organised displays set to take place across the area.
Thousands of visitors are expected at West Dunbartonshire Council’s free display at Levengrove Park on Monday, November 4, with another held in Dalmuir the following night.
The 20-minute shows will feature a range of fireworks, including comets, mines, spinners, hummers, whistles, strobes and dragon’s eggs, and will light up the sky in an array of colours.
Both events begin at 7pm and finish at 9pm.
Along with the main event, there will be family activities and stalls selling hot food.
Visitors are advised to arrive in plenty of time and, if possible, walk to the event or use public transport as many of the streets around the parks will have parking restrictions in place.
People are being urged not to bring their own fireworks or sparklers as these can present a safety issue within large crowds, and are also advised to leave pets at home.
Around 5,000 spectators are ecpected to attendf each event.
The council posted on Facebook:
“It’s Fireworks Night! Watch the skies fill with dazzling fireworks and enjoy funfairs and family activies.
“Join thousands of spectators as Levengrove Park is illuminated with dazzling fireworks.
“Tuck into food from various stalls or enjoy family activities throughout the park.”
Visitors are asked to arrive at the events in plenty of time to avoid disappointment, adhere to parking restrictions in and around the venues and follow advice from the stewards at all times.
Helensburgh and District Round Table will also hold their annual bonfire and fireworks display on Saturday, November 2.

A ring is a structure containing:
where the structure defined on the operations are:
Examples of rings would be natural, real, complex and rational numbers. Any algebra over a ring is also a ring. Hence, any set of n × n matrices of real numbers also forms a ring. A set of real upper or lower triangular matrices would also form a ring. The family of rings starts from semirings and goes on with commutative semirings, rings and commutative rings.
open import Agda.Primitive using (Level; _⊔_; lsuc; lzero)
open import Types.product
open import Types.relations
open import Types.equality
module Algebra.rings {a ℓ} {A : Set a} (_==_ : Rel A ℓ) where
open import Types.operations (_==_)
open import Algebra.groups (_==_)
The family of rings consist of a set and two binary operations. Each binary operation behaves in a certain way with the set, taking upon roles from the group family, e.g. one operation can behave like a monoid with respect to the set while the other one can behave like a group.
| Object ↓ Operation → | + behaves as |
* behaves as |
|---|---|---|
| Near-Semiring | Monoid | Semigroup |
| Semiring | Commutative Monoid | Monoid |
| Commutative Semiring | Commutative Monoid | Commutative Monoid |
| Ring | Abelian Group | Monoid |
The *
operation interacts with the +
operation by folowing the law of distributivity.
We define a Near-Semiring as the most abstract structure in the family of rings. It is a structure containing:
where the structure defined on the operations are:
record IsNearSemiring (+ * : ★ A) (0# : A) : Set (a ⊔ ℓ) where

A Semiring is a structure containing:
where the structure defined on the operations are:
These laws are the same as that of a ring, except for the requirement of addition to have an inverse operation. It is easier to first describe the semiring with the annihilation element:

And now the complete definition:

Summary
“Clickjacking” (which is a subset of “UI redressing”) is a malicious technique that consists of deceiving a web user into interacting (in most cases by clicking) with something different to what the user believes they are interacting with. This type of attack, that can be used alone or in combination with other attacks, could potentially send unauthorized commands or reveal confidential information while the victim is interacting with seemingly harmless web pages. The term “Clickjacking” was coined by Jeremiah Grossman and Robert Hansen in 2008.
A Clickjacking attack uses seemingly innocuous features of HTML and Javascript to force the victim to perform undesired actions, such as clicking a button that appears to perform another operation. This is a “client side” security issue that affects a variety of browsers and platforms.
To carry out this type of technique the attacker has to create a seemingly harmless web page that loads the target application through the use of an iframe (suitably concealed with CSS code). Once this is done, the attacker could induce the victim to interact with his fictitious web page by other means (through, for example, social engineering). Like other attacks, a common prerequisite is that the victim is authenticated against the attacker’s target website.
Once the victim is surfing on the fictitious web page, he thinks that he is interacting with the visible user interface, but effectively he is performing actions on the hidden page. Since the hidden page is an authentic page, the attacker can deceive users into performing actions they never intended to perform through an “ad hoc” positioning of the elements in the web page.
The power of this method is due to the fact that the actions performed by the victim are originated from the authentic target web page (hidden but authentic). Consequently some of the anti-CSRF protections, that are deployed by the developers to protect the web page from CSRF attacks, could be bypassed.
How to Test
As mentioned above, this type of attack is often designed to allow an attacker site to induce users’ actions on the target site, even if anti-CSRF tokens are being used. So, it’s important, like for the CSRF attack, to individuate web pages of the target site that it take input from the user.
We have to discover if the website that we are testing has no protections against clickjacking attacks or, if the developers have implemented some forms of protection, if these techniques are liable to bypass. Once we know that the website is vulnerable, we can create a “proof of concept” to exploit the vulnerability.
The first step in discovering if a website is vulnerable is to check if the target web page could be loaded into an iframe. To do this you need to create a simple web page that includes a frame containing the target web page. The HTML code to create this testing web page is displayed in the following snippet:

<title>Clickjack test page</title>

Website is vulnerable to clickjacking!

Result Expected: If you can see both the text "Website is vulnerable to clickjacking!" at the top of the page and your target web page successfully loaded into the frame, then your site is vulnerable and has no type of protection against Clickjacking attacks. Now you can directly create a "proof of concept" to demonstrate that an attacker could exploit this vulnerability.
Bypass Clickjacking protection:
In case in which you only see the target site or the text "Website is vulnerable to clickjacking!" but nothing in the iframe this mean that the target probably has some form of protection against clickjacking. It’s important to note that this isn’t a guarantee that the page is totally immune to clickjacking.
Methods to protect a web page from clickjacking can be divided in two macro-categories:
- Client side protection: Frame Busting
- Server side protection: X-Frame-Options
In some circumstances, every single type of defense could be bypassed. Following are presented the main methods of protection from these attacks and techniques to bypass them.
Client side protection: Frame Busting
The most common client side method, that has been developed to protect a web page from clickjacking, is called Frame Busting and it consists of a script in each page that should not be framed. The aim of this technique is to prevent a site from functioning when it is loaded inside a frame.
The structure of frame busting code typically consists of a "conditional statement" and a "counter-action" statement. For this type of protection, there are some work arounds that fall under the name of "Bust frame busting". Some of this techniques are browser-specific while others work across browsers.
Mobile website version
Mobile versions of the website are usually smaller and faster than the desktop ones, and they have to be less complex than the main application. Mobile variants have often less protection since there is the wrong assumption that an attacker could not attack an application by the smart phone. This is fundamentally wrong, because an attacker can fake the real origin given by a web browser, such that a non-mobile victim may be able to visit an application made for mobile users. From this assumption follows that in some cases it is not necessary to use techniques to evade frame busting when there are unprotected alternatives, which allow the use of same attack vectors.
Double Framing
Some frame busting techniques try to break frame by assigning a value to the "parent.location" attribute in the "counter-action" statement.
Such actions are, for example:
- self.parent.location = document.location
- parent.location.href = self.location
- parent.location = self.location
This method works well until the target page is framed by a single page. However, if the attacker encloses the target web page in one frame which is nested in another one (a double frame), then trying to access to "parent.location" becomes a security violation in all popular browsers, due to the descendant frame navigation policy. This security violation disables the counter-action navigation.
Target site frame busting code (target site):
f(top.location!=self.locaton) {
parent.location = self.location;
}
Attacker’s top frame (fictitious2.html):

Attacker’s fictitious sub-frame (fictitious.html):

Disabling javascript
Since these type of client side protections relies on JavaScript frame busting code, if the victim has JavaScript disabled or it is possible for an attacker to disable JavaScript code, the web page will not have any protection mechanism against clickjacking.
There are three deactivation techniques that can be used with frames:
- Restricted frames with Internet Explorer: Starting from Internet Explorer 6, a frame can have the "security" attribute that, if it is set to the value "restricted", ensures that JavaScript code, ActiveX controls, and re-directs to other sites do not work in the frame.
Example:

- Sandbox attribute: with HTML5 there is a new attribute called "sandbox". It enables a set of restrictions on content loaded into the iframe. At this moment this attribute is only compatible with Chrome and Safari.
Example:

- Design mode: Paul Stone showed a security issue concerning the "designMode" that can be turned on in the framing page (via document.designMode), disabling JavaScript in top and sub-frame. The design mode is currently implemented in Firefox and IE8.
onBeforeUnload event
The onBeforeUnload event could be used to evade frame busting code. This event is called when the frame busting code wants to destroy the iframe by loading the URL in the whole web page and not only in the iframe. The handler function returns a string that is prompted to the user asking confirm if he wants to leave the page. When this string is displayed to the user is likely to cancel the navigation, defeating traget's frame busting attempt.
The attacker can use this attack by registering an unload event on the top page using the following example code:

www.fictitious.site

The previous technique requires the user interaction but, the same result, can be achieved without prompting the user. To do this the attacker have to automatically cancel the incoming navigation request in an onBeforeUnload event handler by repeatedly submitting (for example every millisecond) a navigation request to a web page that responds with a "HTTP/1.1 204 No Content" header.
Since with this response the browser will do nothing, the resulting of this operation is the flushing of the request pipeline, rendering the original frame busting attempt futile.
Following an example code:
204 page:
<?php
header("HTTP/1.1 204 No Content");
?>
Attacker's page:

XSS Filter
Starting from Google Chrome 4.0 and from IE8 there were introduced XSS filters to protect users from reflected XSS attacks. Nava and Lindsay have observed that these kind of filters can be used to deactivate frame busting code by faking it as malicious code.
- IE8 XSS filter: this filter has visibility into all parameters of each request and response flowing through the web browser and it compares them to a set of regular expressions in order to look for reflected XSS attempts. When the filter identifies a possible XSS attacks; it disables all inline scripts within the page, including frame busting scripts (the same thing could be done with external scripts). For this reason an attacker could induce a false positive by inserting the beginning of the frame busting script into a request's parameters.
Example: Target web page frame busting code:

Attacker code:
<iframe src=”http://target site/?param=
Attacker code:

Redefining location
For several browser the "document.location" variable is an immutable attribute. However, for some version of Internet Explorer and Safari, it is possible to redefine this attribute. This fact can be exploited to evade frame busting code.
- Redefining location in IE7 and IE8: it is possible to redefine "location" as it is illustrated in the following example. By defining "location" as a variable, any code that tries to read or to navigate by assigning "top.location" will fail due to a security violation and so the frame busting code is suspended.
Example:

- Redefining location in Safari 4.0.4: To bust frame busting code with "top.location" it is possible to bind "location" to a function via defineSetter (through window), so that an attempt to read or navigate to the "top.location" will fail.
Example:

Server side protection: X-Frame-Options
An alternative approach to client side frame busting code was implemented by Microsoft and it consists of an header based defense. This new "X-FRAME-OPTIONS" header is sent from the server on HTTP responses and is used to mark web pages that shouldn't be framed. This header can take the values DENY, SAMEORIGIN, ALLOW-FROM origin, or non-standard ALLOWALL. Recommended value is DENY.
The "X-FRAME-OPTIONS" is a very good solution, and was adopted by major browser, but also for this technique there are some limitations that could lead in any case to exploit the clickjacking vulnerability.
Browser compatibility
Since the "X-FRAME-OPTIONS" was introduced in 2009, this header is not compatible with old browser. So every user that doesn't have an updated browser could be victim of clickjacking attack.
Browser Lowest version
Internet Explorer 8.0
Firefox (Gecko) 3.6.9 (<IP_ADDRESS>)
Opera 10.50
Safari 4.0
Chrome <IP_ADDRESS>2
Proxies
Web proxies are known for adding and stripping headers. In the case in which a web proxy strips the "X-FRAME-OPTIONS" header then the site loses its framing protection.
Mobile website version
Also in this case, since the "X-FRAME-OPTIONS" has to be implemented in every page of the website, the developers may have not protected the mobile version of the website.
Create a "proof of concept"
Once we have discovered that the site we are testing is vulnerable to clickjacking attack, we can proceed with the development of a "proof of concept" to demonstrate the vulnerability. It is important to note that, as mentioned previously, these attacks can be used in conjunction with other forms of attacks (for example CSRF attacks) and could lead to overcome anti-CSRF tokens. In this regard we can imagine that, for example, the target site allows to authenticated and authorized users to make a transfer of money to another account.
Suppose that to execute the transfer the developers have planned three steps. In the first step the user fill a form with the destination account and the amount. In the second step, whenever the user submits the form, is presented a summary page asking the user confirmation (like the one presented in the following picture).
Following a snippet of the code for the step 2:
//generate random anti CSRF token
$csrfToken = md5(uniqid(rand(), TRUE));
//set the token as in the session data
$_SESSION['antiCsrf'] = $csrfToken;
//Transfer form with the hidden field
$form = '
<form name="transferForm" action="confirm.php" method="POST">

BANK XYZ - Confirm Transfer

Do You want to confirm a transfer of '. $_REQUEST['amount'] .' € to account: '. $_REQUEST['account'] .' ?

<input type="hidden" name="amount" value="' . $_REQUEST['amount'] . '" />
<input type="hidden" name="account" value="' . $_REQUEST['account'] . '" />
<input type="hidden" name="antiCsrf" value="' . $csrfToken . '" />
<input type="submit" class="button" value="Transfer Money" />

</form>';
In the last step are planned security controls and then, if all is ok, the transfer is done. In the following listing a snippet of code of the last step is presented (Note: in this example, for simplicity, there is no input sanitization, but it has no relevance to block this type of attack):
if( (!empty($_SESSION['antiCsrf'])) && (!empty($_POST['antiCsrf'])) )
{
//here we can suppose input sanitization code…
//check the anti-CSRF token
if( ($_SESSION['antiCsrf'] == $_POST['antiCsrf']) )
{
echo '
 '. $_POST['amount'] .' € successfully transfered to account: '. $_POST['account'] .'
';
}
}
else
{
echo '
Transfer KO
';
}
As you can see the code is protected from CSRF attack both with a random token generated in the second step and accepting only variable passed via POST method. In this situation an attacker could forge a CSRF + Clickjacking attack to evade anti-CSRF protection and force a victim to do a money transfer without her consent.
The target page for the attack is the second step of the money transfer procedure. Since the developers put the security controls only in the last step, thinking that this is secure enough, the attacker could pass the account and amount parameters via GET method. (Note: there is an advanced clickjacking attack that permits to force users to fill a form, so also in the case in which is required to fill a form, the attack is feasible).
The attacker's page may look like a simple and harmless web page like the one presented below:
But playing with the CSS opacity value we can see what is hidden under the seemingly innocuous web page.
The clickjacking code to create this page is presented below:

<title>Trusted web page</title>

www.owasp.com

<form action="http://www.owasp.com">
<input type="submit" class="button" value="Click and go!">
</form>

With the help of CSS (note the #clickjacking block) we can mask and suitably position the iframe in such a way as to match the buttons. If the victim click on the button "Click and go!" the form is submitted and the transfer is completed.
The example presented uses only basic clickjacking technique, but with advanced technique is possible to force user filling form with values defined by the attacker.

Serie styles
Serie classes apply to line series and scatter. They allow the user to pre-program the style of the series and activate them in a single instruction. There are two default classes which are :
unselected
. It is the default style that is programmed when the API is called without specification, and it is the style that will be displayed when not expressively chosen otherwiseselected
. It is the style applied the serie when it (for the line serie) or one of its points (for the scatter serie) is selected.
Line series
The methods that can set styles are the following:
setLineColor( String serieColor [, String selectionName = "undefined" ] [, bool applyToSelected ] )
-
setLineWidth( Number strokeWidth [, String selectionName = "undefined" ] [, bool applyToSelected ] )
setLineStyle( Number serieStyle [, String selectionName = "undefined" ] [, bool applyToSelected ] )
setMarkers( Object markerFamilies [, String selectionName = "undefined" ] [, bool applyToSelected ] )
showMarkers( [, String selectionName = "undefined" ] )
hideMarkers( [, String selectionName = "undefined" ] )
markersShown( [, String selectionName = "undefined" ] )
setMarkersPoints( String familyName, mixed Points [, String selectionName = "undefined" ] )
Each of these methods take the parameter selectionName
(which defaults with “undefined”, the standard style) that you can specify. In addition to that, some parameters take the boolean applyToSelected
which applies the command not only to the style you are working on, but also to the “selected” style. This is quite useful because it shrinks the number of API calls:
serie.setLineColor('red');
serie.setLineColor('red', 'selected');
// Has similar effect as
serie.setLineColor('red', false, true);
It should be noted that when styles are used in the constructor, they will apply to the “unselected” and to the “selected” styles.
Extending style
You can also extend one style by another one, like this:
serie.extendStyle( String styleTarget, String styleOrigin );
which will extend styleTarget with styleOrigin, provided that the parameter in styleTarget is not defined. In other words, styleTarget parameters have the priority. For the jQuery people, this would correspond to: styleTarget = $.extend( {}, true, styleTarget, styleOrigin );
The select method
Although you could call directly
serie.select( [ String selectName = "selected" ] );
where the parameter selectName
is optional and takes “selected” by default, jsGraph also manages serie selection from its core. Therefore, we advise to call
graph.selectSerie( {Number|String} serieName [, String selectName = "selected" ] );
Extending some marker properties
Sometimes you want to copy some marker styles from one style to another, and you can do it using serie.extendStyle
method. But all the marker properties will be copied, and perhaps you want to apply some post-modification. jsGraph exposes a few methods for that:
setMarkerPoints( newPoints, familyIndex, selectionType )
changes the pointssetMarkersType( newType, familyIndex, selectionType )
changes the markers typesetMarkersZoom( newZoom, familyIndex, selectionType )
changes the markers zoomsetMarkersStrokeColor( newStrokeColor, familyIndex, selectionType )
changes the markers stroke colorsetMarkersStrokeWidth( newStrokeWidth, familyIndex, selectionType )
changes the markers stroke widthsetMarkersFillColor( newFillColor, familyIndex, selectionType )
changes the markers fill color
The familyIndex
parameter relates to the marker family, i.e. the index of the markers to change as was used in the setMarkers
method. familyIndex
defaults to 0. The selectionType
parameter is the name of the selection style for which the style should be overwritten.
Example
Consider the following example:
s.setLineColor('#0710ad');
s.setLineStyle(2);
s.setLineWidth(3);
s.setMarkers([
{
type: 1,
zoom: 1,
strokeWidth: 2,
strokeColor: 'white',
fillColor: '#0710ad'
}
]);
Like we said before, by default, all those methods apply to the “unselected” style. We could decide to create a few more styles, and to extend others from the “unselected” one in several ways.
// Sets the "unselected" line color
s.setLineColor('#0710ad');
// Sets the line style to "unselected" and "selected"
s.setLineStyle(2, false, true);
// Sets the line width to "unselected" and "selected"
s.setLineWidth(2, false, true);
// Sets the markers to "unselected" and "selected"
s.setMarkers(
[
{
type: 1,
zoom: 2,
strokeWidth: 2,
strokeColor: 'white',
fillColor: '#0710ad'
}
],
false,
true
);
// Sets the color for "selected"
s.setLineColor('#2e7c14', 'selected');
// Overwrites the previously set line style of "selected" (see the 2nd command line)
s.setLineStyle(1, 'selected');
// Creates a new style "extended" and extends it from "unselected"
s.extendStyle('extended', 'unselected');
// Overwrites the line width
s.setLineWidth(4, 'extended');
// Copy "custom1" into the new style "custom2"
s.extendStyle('custom2', 'custom1');
// Overwrite some of the marker properties in "custom2"
s.setMarkersStrokeColor('#247c4e', 1, 'custom2');
s.setMarkersFillColor('#6fb590', 1, 'custom2');
// You have to draw the series at the end
graph.draw();

@Phil94comp : thanks for asking the questions! Thanks for sticking with this. Lando saves us time and confusion when setting up postgres and solr locally, but it'll be totally possible to get this setup without lando -- it'll just require more time and experimentation, so thanks for your willingness on both of those.
You will still want to run the remaining rake tasks, which are responsible for setting up the databases and adding some sample data to them. The dss:servers:start
one is the only one that relies on lando.
For the solr config in blacklight.yml: when you start solr, are you able to go to your browser and see the solr interface at http://localhost:8983/solr? If so, you can use the solr interface to create a new core using the configuration in solr/conf within this repo. You would then set url
in the configuration file to http://localhost:8983/solr/name-of-the-core-you-made
.
For the postgres config in database.yml, it's a similar story. Are you able to connect to the database at localhost:5432 with a particular username and password? Does the user have the permissions to create a new database? If so, you could use localhost
as the host, 5432
as the port, the username and password you used. If not, you may have to configure your local version of postgresql differently (different port, different username, etc.)
I should say, that instead of editing the configuration files, you could set the environment variables in your terminal. So, for example, if postgres is running at port 5432, you could leave the config file intact, you could type the following command into cmd/powershell before running other commands.
set lando_dss_database_conn_port=5432

“Even so, we must face the fact that God’s interaction with his creation is not always constructive and restorative but is often shockingly destructive. It is true that the destruction always precedes some kind of renewal, but it is destruction all the same, and while we can come up with the comforting scenarios in which we do the same kind of thing — controlled burns in forest management and farming, for instance — it would be best not to allegorize too readily. God loves his creation, but he deals with it in ways that, to us, are sometimes indistinguishable from hatred. As he deals with us.”
— Alan Jacobs, “Blessed Are the Green of Heart,” in Wayfaring, p. 126

Final Foundation Reflections
Three things ive learnt about myself:
I can shut down when i'm overwhelmed. I dont feel like talking and can be quite grumpy which is something i'll obviously need to work on.
Theres a huge difference in clarity between my 'fresh mind' and my 'tired mind'. There were several moments where i'd struggle with something for a very long time but after a small break the answer would come to me.
I definitely learn better by doing.
The role of VALUES, EMPATHY and SELF AWARENESS in learning and programming:
In a nutshell it's about being good to yourself and to others. As stated above. Ive come to realise I work vastly better when i'm fresh and focused. Knowing this means i'll know that taking a quick break will save time compared to pushing through in a fog.
You need to be aware of your failings so you can mitigate and improve them whilst also leaning into your strengths.
Generally in life and so in programming you will work collaboratively with others. Being aware of yourself and the needs of your collaborators will make things run more smoothly.
What suprised you the most about the core learning:
Working in physical jobs for most of my life there was a tendency to just push through. Its been a struggle to put that mentality aside. This core has shown me that its a lot harder to do when doing things that utilise your mental faculties more.
Why Dev concentrates on this:
Being more aware of yourself and others makes you a better learner, a better person and a better employee. So its a very important skill to learn.
Was it worth it:
Programming skills will come with time and practice. The core skills learnt in foundations however will increase the speed at which I will learn carrying on into the future and will make me more employable and a better team member. The most useful skill its taught me is a much better awareness of my potential failings so that I can improve these.


Trump says yet to decide whether to close trade deal with China
WASHINGTON (Reuters) - President Donald Trump said on Friday a potential U.S.-China trade deal was coming along well, but he had yet to decide whether he wanted to finalize it.
“The China deal is coming along very well. The question is whether or not I want to make it,” Trump told reporters at the White House.

Jennifer Nettles’ Calls Out Country Radio At Female-Focused CMA Awards: ‘Play Our F*@#!n Records’
by Brent FurdykJennifer Nettles sure knows how to make a fashion statement — or, rather, how to make a statement with fashion.
The Sugarland singer hit the red carpet of Wednesday’s CMA Awards making a bold fashion move to push for female equality in country music. Nettles chose a white Christian Siriano pantsuit featuring the words “Equal Play.” She accessorized with a hot-pink train displaying a female Venus symbol and “Play Our F*@#iN Records Please & Thank You” written across it.
That’s a significant statement to make at this particular edition of the CMAs, which is focusing specifically on female artists while bringing together three of them — Dolly Parton, Carrie Underwood and Reba McEntire — together to host. The awards show is making history with it being the first time women are nominated in every single category, with one exception – Male Vocalist of the Year.
Miranda Lambert has been among the female country artists to call attention to country radio’s disparity between the frequency that male artists are played in comparison to females.
“It’s B.S., straight up! Carrie Underwood still struggles, and that just blows my mind because she’s got a million hits and she’s Carrie Freakin’ Underwood,” Lambert told Redbook. “I tell them at the radio stations, ‘Just play one of us; it doesn’t have to be me. Then we all win.’ I’ll fight for it until I can’t no more.”
The 53rd annual CMA Awards take place on Wednesday, Nov. 13.

Nebraska eases restrictions to address propane shortage
LINCOLN, Neb. (AP) - Nebraska is temporarily lifting weight restrictions on trucks carrying propane to address a shortage of heating fuels.
State officials have suspended the 90,000-pound gross weight limit for motor carriers hauling critically needed heating fuels through Dec. 15. Lt. Gov. Mike Foley issued the order Thursday on behalf of Gov. Pete Ricketts, who is out of the state.
Officials say drivers exceeding the normal weight limits must carry a copy of the executive order to document that they are providing direct support to the state. The order doesn’t apply to the interstate system.
State officials say the shortage isn’t serious but they’re monitoring it. They say more extreme shortages in surrounding states have increased the need to transport through Nebraska.

UEFA charge Belgium over Boyata, Batshuayi mixup
by Agency ReportBelgium have been charged by UEFA after Dedryck Boyata wore Michy Batshuayi’s shirt for part of their European Qualifier against Russia on Saturday.
Boyata, who was officially named on the team sheet as No 4, appeared for the second half with the correctly numbered shorts but combined with Batshuayi’s No 23 top.
Players sometimes change into a fresh shirt at half-time and Sky Sports News has been told that Boyata mistakenly picked up the wrong one in the changing room.
The error was not spotted by Belgium’s backroom staff until some time after the teams kicked off and the former Celtic and Manchester City defender only switched back to his assigned number in the 57th minute.
The Belgian FA has been charged under article 43 (1) of the competition regulations which state: ‘Before each match, each team shall indicate in the relevant match sheet the numbers, full names, dates of birth and, if applicable, shirt names of the 23 players in the squad’.
Belgium have also been handed a ‘delayed kick-off’ charge relating to the same game but there is no confirmation whether this is related to the shirt error.

| SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
java.lang.Object dxf2svg.svg.Point
The Point class encapsulates the smallest element used in the conversion
between DXF and SVG.
Each Point object has several useful methods including auto conversion
to SVG space and units and the ability to determine if one Point is
within close proximity to another.
All Points include X, Y and Z space coordinates but the Z coord
is not used by SVG, but is included for future projects.
The toString()
method has be overwritten from its
base class, Java.lang.Object, but is joined by several other useful
toString()
methods that allow a point to express itself
in a different manner depending on context. So objects such as SVGCircle
can call the toStringCircle()
and get the unique
SVG syntax for describing a circle's centre point.

DNA and RNA are used to direct the activity of cells. For example, DNA contains directions (genes) that cause cells to look and function a certain way.
Nucleic Acids have three Parts:
Nucleic acids are linked together to form long chains, and DNA is made of two parallel chains:
Here is what they look like all put together:
These parallel chains have a twist to them so DNA is often called a Double Helix.

Bluckdb
It is a Key/Value store that implements bucketing based on extendible hashing
The server.go
file is a simple http server that answers on the 2233 port.
There are 3 endpoints :
curl -XGET http://hostname:2233/?id=<key>
curl -XPUT -d 'value' http://hostname:2233/?id=<key>
curl -XGET http://hostname:2233/meta
curl -XGET http://hostname:2233/debug?page_id=<id_of_the_page_to_display>
The goal
The goal of this project is to explore and to reinvent the wheel of well known, state of the art, algorithms and data structures. For experimental and learning purpose only, not production ready.
Design
A Directory is a table of buckets called "Page".
A Page is a byte array of 4096 bytes length, append only. Trailer : It stores actual usage of the Page at 4094 bytes (unint16), and local depth at 9092 bytes (unint16)
A Record is a byte array with a key, a value and the headers :
type Record interface {
Key() []byte
Val() []byte
KeyLen() uint16
ValLen() uint16
}
type ByteRecord []byte
Actual public methods :
- put : append the record at the offset given by
Page.use()
value - get : read in reverse way, starting from the end and iterating until the key is found, or the beginning
This design allows updating values for a given key without doing lookup before inserting (put is O(1) if the Page is not full). When the Page is full, the Directory.split()
method skips the old values of the same key and re-insert just the latest
How to start
Get the package
go get github.com/BenJoyenConseil/bluckdb
If you run a go program for the first time, do not forget to setup your GOPATH : export GOPATH=$HOME/Dev/go
Run the server
go run server.go
It runs an httpserver with an instance of MmapKVStore which opens/creates the datafile on the /tmp/bluck.data
path.
Note : the path will change in the futur.
