As the complexity and functionality of web applications has grown, so has Chrome DevTools. In this recap of Paul Irish's Google I/O 2013 talk Chrome DevTools Revolutions 2013, you get a look at the latest features that are revolutionizing how you build and test web applications.
If you missed Paul's talk, you can catch it above (go ahead, we'll wait) or you can cut straight to the feature roundup:
Workspaces lets you use DevTools as your source code editor.
If you use Sass, you'll love the ability to live-edit Sass (.scss) files within DevTools and see your changes immediately reflected on the page.
Remotely debugging pages on Chrome for Android has been possible for a while, but the ADB extension makes connecting to Android devices simpler. Reverse port forwarding lets you easily connect to localhost on your development machine from your device.
Performance is always a concern in web applications, and DevTools has a number of new features to help you track down bottlenecks, including the new Flame Chart visualization for CPU profiling and several new tools for debugging performance problems related to rendering and memory use.
These features are live in Chrome 28, now available in the stable update channel.
Workspaces let you map resources served from a local web server to files on disk, so you can edit any type of source file within the Sources panel and have those changes persist to disk. Similarly, changes you make in your external editor immediately appear in the Sources panel.
The screenshot below shows an example of workspaces in action. The Calendar site has been loaded over localhost, while the Sources panel shows the local file system view of the site's root folder. Edits you make to the files in this folder are persisted to disk. In the screenshot below, some unsaved changes have been made to Calendar.css, so an asterisk is placed next to the file name.
Pressing Control+S or Command+S persists the changes to disk.
Similarly, changes you make to an element's styles in the Elements panel are reflected in both the Sources panel and your external editor. Note that:
DOM changes in the Elements panel are not persisted. Only style changes on the Elements panel are persisted.
Only styles defined in an external CSS file can be changed. Changes to element.style or to inline styles are not persisted back to disk. If you have inline styles, they can be changed on the Sources panel.
Style changes on the Elements panel are persisted immediately; you don’t need to press Control+S or Command+S.
There are two parts to using workspaces: making a local folder's contents available to DevTools, and mapping that folder to a URL.
To add a new workspace folder:
In DevTools, click Settings to open DevTools Settings.
Click Workspace.
Click Add Folder.
Browse to the folder containing your project's source files and click Select.
When prompted, click Allow to allow DevTools full access to the folder.
The Sources panel displays the new workspace folder along with the sources loaded over localhost. You can now live-edit files within your workspace folder, and those changes will persist to disk.
Once you've added a workspace folder you can map it to a URL. Whenever Chrome loads the specified URL, the Sources panel displays the workspace folder contents in place of the network folder contents.
To map a workspace folder to a URL:
In the Sources panel, right-click or Control+click on a file in a workspace folder.
Select Map to Network Resource.
Select the corresponding network resource from the currently loaded page.
Reload the page in Chrome.
The Sources panel should now show just the contents of your site's local workspace folder, not the localhost sources, as shown below.
Note: If you still see the localhost sources, refresh the page in Chrome.
There are two other ways to link a network folder to a workspace folder:
Right-click (or Control+click) on a network resource and select Map to File System Resource.
Add mappings manually in the Workspace tab of the DevTools Settings dialog.
Sass (CSS Source Map) debugging lets you live-edit Sass (.scss) files in the Sources panel, and view the results without having to leave DevTools or refresh the page. When you inspect an element whose styles are provided by a Sass-generated CSS file, the Elements panel displays a link to the .scss file, not the generated .css file.
Clicking the link opens the (editable) SCSS file in the Sources panel. You can make any changes you want to this file.
When you save changes to an SCSS file (in DevTools or elsewhere), the Sass compiler re-generates the CSS files. Then DevTools reloads the newly generated CSS file.
Note: Technically this feature should work with any CSS preprocessor that supports source maps. For more information, read working with CSS preprocessors in the DevTools documentation.
To use Sass debugging in Chrome you need to have the pre-release version of the Sass compiler, which is the only version that currently supports source map generation.
gem install sass -v '>=3.3.0alpha' --pre
You also need to enable the Sass debugging feature in DevTools experiments:
Open about:flags in Chrome.
Turn on Enable Developer Tools experiments.
Restart Chrome.
Open DevTools Settings and click Experiments.
Turn on Support for Sass (or Sass stylesheet debugging, depending on the browser version you're using).
Once Sass is installed, start the Sass compiler to watch for changes to your Sass source files and create source map files for each generated CSS file, for example:
sass --watch --sourcemap sass/styles.scss:styles.css
If you are using Compass, note that Compass doesn’t yet support the pre-release version of Sass, so you can’t use Sass debugging with Compass.
For each SCSS source file it processes, the Sass compiler generates a source map file (.map file) in addition to the compiled CSS. The source map file is a JSON file that defines the mappings between the .scss file and the .css files. Each CSS file contains an annotation that specifies the URL of its source map file, embedded in a special comment:
/*# sourceMappingURL=<url> */
For instance, given the following SCSS file:
<!-- styles.scss --> $textSize: 26px; $fontColor: red; $bgColor: whitesmoke; h2 { font-size: $textSize; color: $fontColor; background: $bgColor; }
Sass generates a CSS file like this, with the sourceMappingURL annotation:
<!-- styles.css --> h2 { font-size: 24px; color: orange; background-color: darkblue; } /*# sourceMappingURL=styles.css.map */
Below is an example source map file:
{ "version": "3", "mappings":"AAKA,EAAG;EACC,SAAS,EANF,IAAI;EAOX,KAAK..." "sources": ["sass/styles.scss"], "file": "styles.css" }
A couple of new features in DevTools make remote debugging on Chrome for Android easier to setup: the ADB extension and reverse port forwarding.
The ADB Chrome extension simplifies the process of setting up remote debugging. It provides the following benefits:
Bundles Android Debug Bridge (ADB) so you don't have to install it.
No command line interaction required.
UI for easily starting and stopping the ADB daemon, and viewing connected devices.
Reverse port forwarding makes it easy to connect Chrome on Android to a web server running on your localhost, something that some network environments make difficult without some DNS tricks.
First, install the ADB Chrome extension from the Chrome Web Store. Click Add to Chrome to install the extension.
Installing extensions from the Chrome Web Store isn't supported on Windows 8. If you have any problems installing from the Chrome Web Store, see Remote Debugging on Android for alternate installation instructions.
Once installed, a gray Android menu icon appears in Chrome. To start ADB, click the icon and then click Start ADB.
Once ADB has started, the menu icon turns green and displays the number of currently connected devices, if any.
Click View Devices to open the about:inspect page that displays each connected device and its tabs. To inspect a tab in DevTools, click the "inspect" link next to its URL.
If you don't see any connected devices, check that your device is connected to USB, and that USB debugging is enabled in the Chrome for Android settings. For more detailed instructions and troubleshooting steps, see Remote Debugging on Android.
Commonly you have a web server running on your local development machine, and you want to connect to that site from your device. If the development machine and the device are on the same network, this is straightforward. But in some cases, like on restricted corporate networks, this may not be possible without some clever DNS tricks. A new feature in Chrome for Android called reverse port forwarding makes this simple to do. It works by creating a listening TCP port on your device that forwards traffic over USB to a particular TCP port on your development machine.
To use this feature you will need:
Chrome 28 or later installed on your development machine
Chrome for Android Beta installed on your device
Android Debug Bridge (ADB Chrome extension or full Android SDK) installed on your development machine
To use reverse port forwarding, you need to have your device connected for remote debugging, as described in Using the ADB extension. Then you need to enable reverse port forwarding and add a port forwarding rule for your application.
First, enable reverse port forwarding:
Open Chrome on your development machine.
In about:flags, turn on Enable Developer Tools experiments and restart Chrome.
Open about:inspect. You should see your mobile device and a list of its open tabs.
Click the "inspect" link next to any of the sites listed.
In the DevTools window that opens, open the Settings panel.
Under Experiments, turn on Enable reverse port forwarding.
Close the DevTools window and return to about:inspect.
Then add a port forwarding rule:
Click the "inspect" link again to open DevTools, and open DevTools Settings again.
Click the Port Forwarding tab.
In the Device port field, enter the port number Chrome should connect to on your Android device (defaults to 8080).
In the Target field, append the port number where your web application is running on your development machine.
You should see the content being served by your development machine.
The new Flame Chart view provides a visual representation of JavaScript processing over time, similar to those found in the Timeline and Network panels.
The horizontal axis is time and vertical axis is the call stack. Across the top of the panel an overview that shows the entire recording, and you can "zoom in" on a region of the overview by selecting it with your mouse, as shown below. The details view timescale shrinks accordingly.
In the details view a call stack is represented as a stack of function "blocks". A block that sits atop another was called by the lower function block. Hovering over a given block displays its function name and timing data:
Name — The name of the function.
Self time — How long it took to complete the current invocation of the function, including only the statements in the function itself, not including any functions that it called.
Total time — The time it took to complete the current invocation of this function and any functions that it called.
Aggregated self time — Aggregate time for all invocations of the function across the recording, not including functions called by this function.
Aggregated total time — Aggregate total time for all invocations of the function, including functions called by this function.
Clicking a function block opens its containing JavaScript file in the Sources panel, at the line where the function is defined.
To use the flame chart:
In DevTools, click the Profiles tab.
Choose Record JavaScript CPU profile and click Start.
When you are done collecting data, click Stop.
In the profile view, select the Flame Chart visualization.
Rounding out this survey of revolutionary advances in DevTools are several new feature for investigating performance issues:
Continuous painting mode
Showing Paint rectangles and layer borders
FPS meter
Finding forced synchronous layouts (layout thrashing)
Object allocation tracking
Continuous painting mode is an option in DevTools Settings (Rendering > Enable continuous page repainting) that helps you identify the rendering cost of individual elements or CSS styles.
Normally, Chrome only paints to the screen in response to a layout or style change, and only those regions of the screen that need updating. When you enable continuous page repainting, the entire screen is being constantly repainted. A heads-up display shows the time it's taking Chrome to paint the page, as well the range of times, and a graph showing the distribution of recent paint times. The horizontal line across the histogram indicates the 16.6 ms mark.
The benefit to using this is that you can walk the DOM tree in the Elements panel and hide individual elements (press the H key to hide the currently selected element), or disable an element's CSS styles. You can see how much time one element or style adds to the page render "weight", if any, by noticing changes to the page paint time. If hiding a single element brings the paint times down significantly, you know to focus on the styling or construction of that element.
To enable continuous paining mode:
Note: If you don't see this option in Settings, open about:flags, turn on GPU compositing on all pages, and restart Chrome.
For more information, see Profiling Long Paint Times with DevTools' Continuous Painting Mode.
Another option in DevTools is to show what rectangular regions of the display are being painted to. (Settings > Rendering > Show paint rectangles). For example, in the screenshot below a paint rectangle is being drawn over the region where a CSS hover effect was being applied to the purple graphic. This is good, since it's relatively small part of the screen.
You want to avoid design and development practices that cause the entire display to be repainted. For example, in the following screenshot the user is scrolling the page. One paint rectangle surrounds the scroll bar, and another surrounds the entire rest of the page. In this case the culprit is the background image on the body element. The image position is set to fixed in CSS, which requires Chrome to repaint the entire page on each scroll.
The FPS meter displays the page's current frame rate, the minimum and maximum frame rate, a bar graph showing frame rate over time, and a histogram that shows frame rate variability.
To show the FPS meter:
Open DevTools Settings.
Click General.
Under Rendering, turn on Force accelerated compositing and Show FPS meter.
You can force the FPS meter to always appear by opening about:flags, turning on FPS counter, and restarting Chrome.
To maximize rendering performance, Chrome normally batches layout changes requested by your application and schedules a layout pass to asynchronously calculate and render the requested changes. However, if an application asks for the value of a layout-dependent property (such offsetHeight or offsetWidth), Chrome is forced to immediately and synchronously perform a page layout. These so-called forced synchronous layouts can significantly reduce rendering performance, especially when performed repeatedly on large DOM trees. This scenario has also been called "layout thrashing".
A Timeline recording alerts you when it detects a forced synchronous layout with a yellow warning icon () next to the corresponding Timeline record. Hovering over one of these records displays stack traces for the code that invalidated the layout, and the code that forced the layout.
This pop-up also shows the number of nodes that needed layout, the size of the re-layout tree, the layout scope, and the layout root.
See Timeline demo: Diagnosing forced synchronous layouts for more information.
Object allocation tracking is a new type of memory profile that shows allocation over time. When you start allocation tracking, DevTools takes heap snapshots continuously over time. The heap allocation profile shows where objects are being created and identifies the retaining path.
To track object allocations:
In DevTools, click the Profiles tab.
Choose Record heap allocations and click Start.
When you are done collecting data, click Stop recording heap profile (the red circle in the lower left corner of the profiling pane).
Finally, here's a completely experimental feature to explore. Canvas profiling lets you record and playback WebGL calls made on a canvas element. You can step through individual WebGL calls or call groups and see the rendered results. You also see the time it took to replay those particular calls.
To use canvas profiling:
Turn on the Canvas inspection feature on the Experiments tab of DevTools settings. (If you don't see this tab, open about:flags, turn on Enable Developer Tools experiments and restart Chrome.)
Click the Profiles tab.
Select Capture canvas frame and click Take snapshot.
You can now explore the calls used to create the canvas frame.


The purpose of the project is to show how people’s attention to democracy has changed over time from the year 1800 to 2000 in 5 different languages area. The covered keywords include democracy, justice, and liberty etc. The project measures people’s attention to the target topic by calculating the percentage of the times the target topic occurs in published books and documents in the year.

Danny Bryden recreates London's most famous landmark in gingerbread.
Equipment and preparation: for this recipe you will need one 25cm square cake board and a small paper flag.
Start by cutting out paper templates of the Big Ben structure. You will need: four clock faces (15 x 10.5cm rectangles); 12 tower sides (12 x 7.5cm rectangles); two clock top and bottoms (15cm square) and four triangular clock roofs (15cm wide at the base x 10cm high x 12.5cm sides).
For the ginger bread, preheat the oven to 200C/400F/Gas 6.
Sift the flour, baking powder and spices into a bowl. Tip half of the mixture into the food processor and add half the butter. Pulse until the mixture resembles breadcrumbs. Tip this into a mixing bowl and repeat with the remaining dry ingredients and butter. Stir in the sugar and mix thoroughly until combined.
Make a well in the centre of the mixture and add in the syrups and molasses. Gradually add the beaten eggs, stirring all the time until the mixture comes together. Divide the dough into ten pieces.
Place a piece of dough between two sheets of baking parchment, and roll out to a thickness of 5-6mm. Repeat with the remaining dough balls.
Cut out the pieces using the templates to trace around, saving and re-rolling any trimmings. Use any leftover dough to create several strips of gingerbread to support the structure while it is being assembled.
Place the pieces on a baking tray lined with parchment paper and transfer to the fridge to rest for 20 minutes.
Use a small knife to mark the lines for the bricks in the tower sides. To make the clock faces, place a neat circle of crushed boiled sweets in the centre of each 'clock face' rectangle. Bake for approximately 8-10 minutes until just colouring at the edges.
Remove from the oven and transfer to a wire rack to cool. When cooled, carefully trim any uneven edges with a sharp knife.
For the sugar syrup, in a pan boil the caster sugar with 150ml/5fl oz water until the colour darkens slightly and thickens, then reduce the heat to minimum so that syrup does not burn but stays warm.
To assemble the gingerbread house, dip the short edge of one tower side piece in the sugar syrup and fix to another side piece. Allow to cool until the sugar syrup sets and then continue with two more pieces to form a square. Repeat until all the tower sides have been used to construct three squares. Stick the three squares together with sugar syrup, one on top of the other, to make a tower.
Use the same method to form the clock face and the pyramid for the roof.
Make up the royal icing by mixing 75ml of cold water with the royal icing sugar and whisking it until smooth. Spoon the icing into a piping bag fitted with a small, plain nozzle.
Attach the clock face to the tower with the royal icing.
Roll out the fondant icing into a large square. Cover the cake board with the fondant icing, trim off any excess and pat down the edges. Place the tower in the centre of the board.
Decorate the clock faces and tower sides using the royal icing. Each tower side should have five vertical lines in icing.
Make the clock hands with liquorice and fix to the face using royal icing. Cover the joins in the tower with liquorice attached with royal icing.
To form 'tiles' on the roof, use royal icing to fix the chocolate buttons in a neat pattern. When set, fix the roof on top of the clock face using royal icing. Place the flag on the top (if using).

What is pirate? @Cryptoon
Cryptoon08-Sep-19 09:39 PM
100% anon z to z transaction assetchain
Mandatory private transactions
So contrary to ZEC for example where something like 10% of transactions is anonymous, with pirate/ARRR 99,99% is anonymous.
Also protected by dPoW
So 51% attack protected
Geert08-Sep-19 09:48 PM
Thank you @Cryptoon i read the website and it's interesting. Appears pirate is the real zec.

I only hold 2 coins.
My investment philosophy is this
If something is that good, it doesn't need my money, to get better. And, I'm not investing in anything without a working product.
I can like a project and not have to hold the coin.
The price is irrelevant, in that situation
Id go as far as to ask, why should I buy? Who's interest is that serving? Bc me losing money is no good for me, and only I care about me.
Geert08-Sep-19 09:55 PM
Mind sharing information with me which 2 coins?
Privatoshi08-Sep-19 09:56 PM
One is BTC & the other is a simple swing trade for today. I can't hold an alt, more than 24 hours, without losing money. So I don't
It doesn't change how I feel about projects, like Komodo.
If it was stock, it would be different.
Komodo is a top project..
Geert08-Sep-19 09:57 PM
A wise man once said, any strategy, even a bad strategy, is better than no strategy.
Privatoshi08-Sep-19 09:58 PM
Another wise man once said, if everyone knew it was a good strategy, they'd be using it, too
Good for me, is profitable
That's what it comes down to
Do you profit?
I've never been rescued by a project, while bagholding.
It's just trading.
If you profit, you're doing it right.
If you don't profit, you're not.
Someone that gets an F, in English, can't be doing it right---just screwed over by this and that.
Privatoshi08-Sep-19 10:40 PM
Lol. Projects get ICO monies. Devs usually get a portion of the supply & they usually mine, which is fair. Centralized exchanges make it out, better than everyone, with listing fees. People very respected in crypto & people with capital, get seed prices and private sales.
And then average users, we get to gather whatever info we can, and TA, and pay a fee and make a simple trade, hoping we can sell higher.
Then miners. They usually have it tough, especially if they are smaller ones.
That's how I see the landscape(edited)
richardt09-Sep-19 01:20 AM
what you're describing sounds like a pyramid scheme
Privatoshi09-Sep-19 02:05 AM
@richardt I disagree. I think it sounds like any other market.
Cryptoon09-Sep-19 06:54 AM
All markets have assymetric information between people on the inside and normies like us
The smaller the market the bigger the assymetry
Markus09-Sep-19 08:42 AM
seems like kmd whales not done yet, many alt coins gaining against btc atm but whales decided to not let kmd be part of it
Cryptoon09-Sep-19 08:49 AM
yeah at this point it's so obvious a lot of accumulating has been going on for so long
I would be surprised if all of a sudden CZ says, well kmd is my biggest bag after bnb and btc its the futur
and pump that shit through the moon and beyond
Markus09-Sep-19 08:52 AM
possible haha
Tek09-Sep-19 08:53 AM
bch is doing quite good
dash too
inb4 dash is trash
Markus09-Sep-19 08:54 AM
we already said most alts doing well
seeing bch doing bad would be strange it does have too many whales holding it, only reason would be if they want to accumulate more
bitmain alone probably hold 1M+ bch
Tek09-Sep-19 08:55 AM
it has a lot of shorts open
on it
Markus09-Sep-19 08:56 AM
roger ver prob also 0.5M
Tek09-Sep-19 08:56 AM
so if it hits the right rate on btc/bch its gonna make a massive green dildo
it might happen in the next few weeks
if btc stays stable
Markus09-Sep-19 08:57 AM
btc is reaching end of symmetrical triangle
i expect it to touch 9800 then move up again
Tek09-Sep-19 08:57 AM
btc gonna stabilise around 10k is my bet
and stay there until close to the next halving
Markus09-Sep-19 08:58 AM
i doubt too long time left
whales need cash flow
Tek09-Sep-19 08:58 AM
yeah altseason time until then : D
Cryptoon09-Sep-19 09:05 AM
does anyone reasonably expect btc to dip below 9k levels or are we just consolidating now for the next btc push up?
Lumbi09-Sep-19 09:09 AM
btc will eventually 'melt' marketshare to alts...
jorian09-Sep-19 09:15 AM
Dear Upbit's Investors,
XMR, DASH, ZEC, XHV, TUBE, PIVX have been put as Investment warning Crypto-asset.
We will inform you of the reasons for specifying details below. If you retain these Crypto-assets, please check the following guides below.


Fruit lanterns are very unique and a cool decoration. Grab a grapefruit or an orange and cut the skin into five pedals. Then take the meat of the fruit out and put in a candle. This works with any citrus fruit.

Confidentiality 机密性
Integrity 完整性
Availability 可用性
Element 元素
Threat 威胁
Computer Security
Preserve the Integrity,Availability and Confidentiality of information system resources (includes hardware,software,firmware,information/data,and telecommunications)
Three Key Objectives
Confidentiality
- Data
- Privacy
Integrity
- Data integrity
- System integrity
Availability
Additional concepts
- Authenticity
- Accountability 可溯源
OSI Security Architecture
Aspects of Security
- Security attack
- Security mechanism: detect,prevent,recover
- Security service
1⃣ Security Attack
Passive Attack
Do not affect system resources , just eavesdropping & monitoring
- Release of Message Contents
- Traffic Analysis
Why Difficult to detect- Message transmission apparently normal
- Emphasis on prevention rather than detection=>Encryption
Active Attack
Try to alter system resources or affect their operation
- Masquerade（伪装）
- Replay=>use nonce to prevent
- Modification of Messages
- Denial of Service(DoS)
Difficult to prevent- The goal is to detect and recover
2⃣ Security Service
1.Enhance security of data processing systems and information transfers of an organization
2.Intended tp counter security attack
3.Using one or more security mechanisms
4.Often replicates functions normally associated with physical documentssignatures,dates...
X.800
- Authentication=>assurance that communicating entity is the one claimed
- Access Control=>prevention of the unauthorized use of a resource
- Data Confidentiality=>protection of data from unauthorized disclosure
- Data Integrity=>assurance that data received is as sent by an authorized entity
- Non-Repudiation=>protection against denial by one of the parties in a communication
- Availability=>resource accessible/usable
3⃣ Security Mechanism
1.Designed to Detect,Prevent,Recover from a security attack
2.No single mechanism that will support all services required
3.One particular element underlies many use of the mechanisms in use:Cryptographic techniques
4.Hence our focus on this topic
Model for Network Security
Requirements of this model
- Design a suitable algorithm for the security transformation;
- Generate the secret information(keys) used by the algorithm;
- Develop methods to distribute and share the secret information;
- Specify a protocol enabling the principals to use the transformation and secret information for a security service.
Model for Network Access Security
Requirements of this model
- Select appropriate gatekeeper functions to identify users;
- Implement security controls to ensure only authorized users access designated information or resources.
Standards
- NIST(National Institute of Standards and Technology)
- FIPS Federal Information Processing Standards
- SP Special Publications
- ISOC Internet Society
- Home for IETF(Internet Engineering Task Force) and IAB(Internet Architecture Board)

Cisco Courses-Network Attacks : A Deeper Look
Network Monitoring Methods
Traffic Information capture methods
- Network TAPs
- Port mirroring
Network TAPs
1.A passive splitting device implemented inline between a device of interest and the network.
2.A tap forwards all traffic including physical layer errors to an analysis device.
3.If it fails or loses power,traffic between the firewall and internal router is not affected.
Traffic Mirroring and SPAN
Enables the switch to copy frames of one or more ports to a Switch Port Analyzer(SPAN) port connected to an analysis device.
Network Security Monitoring Tools
- Protocol Analyzers=>Capture traffic like Wireshark,Tcpdump,etc..
- NetFlow=>Provides a complete audit trail of basic information about every IP flow forwarded on a device
- SIEM=>Security Information Event Management system
- SNMP=>Simple Network Management Protocol
Attacking the Foundation
IP Vulnerabilities
- ICMP Attacks
ICMP was developed to carry diagnostic messages and to report error conditions when routes,hosts,and ports are unavailable.=>Ping of Death & ICMP Flood
- DoS and DDoS Attacks
Prevent legitimate users from gaining access to websites,email,online accounts,and other services;
DDoS=>Larger in magnitude than a DoS attack,attacks introduced new terms such as botnet,handler systems,and zombie computers. - Address Spoofing
A threat actor creates packets with false source IP address information to either hide the identity of the sender or to pose as another legitimate user,then can gain access to otherwise inaccessible data or circumvent security configurations.
- MITM(Man in the middle) Attacks
- Session Hijacking
TCP and UDP Vulnerabilities
TCP Provides Reliable Delivery,Flow Control,Stateful Communication.
TCP attacks target expected protocol behaviors - TCP SYN flood attack
- TCP reset attack
- TCP session hijacking
UDP=>A simple protocol that provides the basic transport layer functions,Connectionless,Lack of encryption
UDP protocol attacks target the lack of protocol behaviors - UDP checksum attack
- UDP flood attack
- UDP DoS attacks
Attacking What We Do
IP Service 👇
ARP Vulnerabilities=>ARP Cache Poisoning
ARP cache poisoning attacks deliberately poison the cache of another computer with spoofed IP address to MAC address mappings.
DNS Attacks
- DNS Open Resolvers(public name servers)
- DNS Stealth Attacks
- DNS Shadowing Attacks=>Hijacked domains are used to create subdomains which are used to resolve to malicious web sites.
- DNS tunneling Attacks=>Hides malicious instructions inside DNS queries and responses.
Use DNS tunneling place non-DNS traffic within DNS traffic to circumvents(规避) security solutions,and the different types of DNS records such as TXT,MX,SRV,NULL,A or CNAME are altered.
DHCP Attack
Could result in every host on the network communication with malicious DNS servers and gateways.A DHCP spoofing attack creates a rouge DHCP server to serve falsified information.
Enterprise Services👇
HTTP & HTTPS
- Malicious iFrames
An iFrame allows a page from a different domain to be opened inline within the current page.It can be used to launch malicious code.
- HTTP 302 cushioning
Allows a web page to redirect and open in a different URL.Can be used to redirected to malicious code.
- Domain shadowing
Malicious web sites are created from subdomains created from a hijacked domain.
Email
- Attachment-based attacks
Email with malicious executable files attached.
- Email Spoofing
Phishing(网络诱骗）attack where the message appears to come from a legitimate source.
- Spam email
Unsolicited email with advertisements or malicious content.
- Open mail relay server
Massive amount of spam and worms can be sent by misconfigured email servers.
- Homoglyphs
Phishing scheme where text characters (hyperlinks) look similar to real text and links.
Web-Exposed Databases
- Command injection attacks
Insecure code and web applications allows OS commands to be injected into form fields or the address bar.
- XSS Cross-site scripting attacks
Insecure server-side scripting where the input is not validated allows scripting commands to be inserted into user generated forms fields, like web page comments.This results in visitors being redirected to a malicious website with malware code.
- SQL injection attacks
Insecure server-side scripting allows SQL commands to be inserted into form fields where the input is not validated.
- HTTP injection attacks
Manipulation of html allows executable code to be injected through HTML div tags, etc.

In this article, I would like to go through the procedures on how software and hardware testing takes place in Robotics and Self Driving Vehicle Industry.
So let us first look into Software Testing. In Robotics software development, three types of tests are prevalent. 1. Unit Testing, 2. Integration Testing,
and 3. Regression Testing.
1. Unit Testing
Unit test refers to testing individual functionality or a section of a software System or application (also called Unit) to ensure its design and behavior
with the standard expectations. In procedural programming paradigm, a unit can be an entire module, a function or a procedure. On the other hand, in Object
Oriented Programming, a unit can be an entire class or a method of the class.
Some of the common unit testing frameworks are gtest, pytest and unittest. In this article we will be discussing gtest and pytest.
Gtest is a testing framework which is developed by google for testing c++ programs. These can be easily integrated with ROS and hence they are very
useful for Robotics Applications.
When using gtest you start writing the Assertion
statements that checks whether a condition is true.

HIGH COURT OF JAMMU AND KASHMIR AT JAMMU. WPPIL No. 20 OF 2011 Yash Bhashin Petitioners State and ors. Respondent !Mr SK Anand, Adv. ^Mr Gagan Basotra, Sr.AAG, Mr SS Nanda, Adv. Honble Mr Justice Virender Singh, Judge Honble Mr Justice Muzaffar Hussain Attar,Judge Date: 10.09.2012 :J U D G M E N T :
Muzaffar Hussain Attar:
We the people of India have given to ourselves the Constitution, from the bossom of which are born three principal organs of the State viz., Legislature, Executive and Judiciary. In view of the mandate contained in the Constitution, all the three organs of the State have to function within the frontiers delineated by the Constitution itself. The legislature has to legislate the laws and the executive, which is answerable to the legislature, has to implement the said laws. Amongst others, the principal and fundamental functions of the Courts are to interpret the laws and resolve the disputes between the litigating parties, which disputes are brought before them.
Because of the disability from which certain sections of the society are suffering from viz., down-trodden class of the society, the children and women folk, and further in order to protect the environment, a national asset, the Constitutional Courts have been entertaining the petitions which are in public interest or even at times, have been taking suo-moto cognizance of the issues which have impact on large sections of the society. The 2/ Constitutional Courts have opened the doors for such proceedings for the benefit of under-privileged class of the society.
The failure on the part of the Statutory and administrative authorities in effectively implementing the statutes and carryingout the mandate of the political bosses in public interest and in accordance with the law, results in subjecting the common masses to incalculable sufferings and untold miseries. The inaction and non-performance/poor performance on the part of the statutory and administrative authorities results in depriving the basic facilities/amenities to the man on street. The amenities and the facilities which are to be provided to the people at large, have many shades. The people are approaching the courts now by filing the Public Interest Litigation complaining therein that even the basic civic facilities are not being made available to them. The products/commodities which are hazardous to human life and which endanger the environment, even though, their manufacture and circulation is banned by laws, are still available in abundance.
Such type of litigations are eating into public time of the courts which is, otherwise, to be devoted for resolving the disputes between the parties which are brought before the Constitutional Courts and other courts. In the above stated backdrop and for above reasons, the issues raised in this Public Interest Litigation have surfaced.
Legislatures are painting rainbow of rights, which due to cruel defiance of some persons, who are duty bound to translate them into reality, get eclipsed under dark clouds of insensitivity. Petitioner in this Public Interest Litigation has prayed for issuance of directions to the respondents which besides State of J&K, include J&K State Pollution Control Board, Commissioner, 3/-
Municipal Corporation, Jammu and the Deputy Commissioner, Jammu, for implementing the provisions of the Environment (protection) Act of 1986, Plastic Waste (Management and Handling) Rules, 2011, Municipal Solid Waste (Management & Handling) Rule, 2000, the Jammu and Kashmir Non- Biodegradable Material (Management, Handling and Disposal) Act, 2007 and the Rules made thereunder.
If the authorities, who are charged with the duties to implement such laws, would discharge their duty honestly and diligently, such type of petitions would not be filed. One of the functions of the Courts is to direct implementation of laws, if it is complained that the same are not being implemented by the authorities concerned. Such a situation can arise once in a blue moon. Unfortunately, this court is being flooded with Public Interest Litigations. The Commissioner, Municipal Corporation, Jammu and the Chairman, J&K State Pollution Control Board, Jammu, who are present in the court, have assured that those of the laws which are to be implemented by these authorities will be implemented faithfully by them.
The grievances projected in this Public Interest Litigation are of significant importance and the respondent-State and its authorities would be duty bound to take measures and remedial steps to redress the grievances of people at large. The issues raised in this petition are manifold and significant. Among others, it has surfaced that Municipal Corporation, Jammu is not making all out efforts to keep the city clean and create hygienic conditions. The State Pollution Control Board, in view of the averments made in the petition is found 4/-
lacking in taking effective and stringent action in accordance with the law against violators of the law.
Keeping this petition on the files of this Court any further is not required and is disposed of in the following manner:- 1/ Respondents who are present in person in the court, are directed to take all effective steps and gear up the statutory and administrative machinery for implementing the provisions of the Environment (protection) Act of 1986, Plastic Waste (Management and Handling) Rules, 2011, Municipal Solid Waste (Management & Handling) Rule, 2000, the Jammu and Kashmir Non- Biodegradable Material (Management, Handling and Disposal) Act, 2007 and the Rules made thereunder.
2/ The Commissioner/Secretary, Urban and Local Bodies, J&K State, is directed to monitor the functioning of the Municipal Corporation, Jammu for implementing these laws and maintenance of the cleanliness and hygienic conditions of Jammu city.
3/ The Commissioner/Secretary Urban and Local Bodies is further directed to supervise the functioning of Municipal Corporation, Srinagar, and all other Municipal Committees of the Jammu and Kashmir State;
4/ The Competent/disciplinary authorities are directed to seek periodical reports from all the concerned authorities; 5/ The Commissioner/Secretary, Urban and Local Bodies, shall initiate or order initiation of disciplinary proceedings against all such officers/officials who would be lacking in their performance of duty and would show utter dis-regard to the provisions of statute and instructions of superiors;
5/-
6/ The J&K State Pollution Control Board, Jammu, shall take all effective steps in implementing the provisions of the Environment (Protection) Act, 1986 and the The Air (Prevention and Control of Pollution) Act, 1981, The Water (Prevention and Control of Pollution) Act, 1974, and The Chairman of the Board shall be personally responsible to effectively implement the provisions of the aforementioned Act;
7/ It is further provided that if any of the members of the society would have any grievance against the functioning of the officers/officials of the departments concerned, then, the same shall be brought to the notice of the Competent/Disciplinary authority, who shall be under an obligation to consider and take a decision on such complaints preferably within four weeks from the date, such complaints are received and convey the results thereof to the aggrieved person(s).
The orders passed in this Petition, from time to time, shall become part of this order and the directions issued, shall be carried out in letter and spirit.

'My Best Friend's Wedding'
A movie review by Walter Frith
Anyone who has ever been deeply involved in a wedding party knows that sometimes a wedding is not always so wonderful and romantic as some sentimentals make it out to be. Julia Roberts has a first hand experience at this in 'My Best Friend's Wedding'. Roberts plays a food critic in NYC who gets a phone call from her best (male) friend (Dermot Mulroney) and he informs her that he's getting married. It comes as a shock since its Wednesday and the wedding is in four days. Roberts tells her gay editor (Rupert Everett in the film's best performance in a sly supporting role that will grow on you) that she has four days to 'break up the wedding' because she feels the woman marrying Mulroney (Cameron Diaz) is all wrong for him and that she has secretly been in love with him all these years but somehow didn't tell him.
As I was watching this movie I loved part of it and hated part of it. That is really strange. I don't consider myself a romantic and I've only been to one wedding in the last ten years. Don't get me wrong, I believe in marriage; heck, my parents just celebrated their 49th wedding anniversary on July 1st. What I really found odd was the mixture of characters being in this situation and at times appearing very unattractive in their qualities and at other times I wanted to give each of them a hug. It was like I was watching two different people (especially in Roberts and Diaz) with split personalities. Julia Roberts is somewhat inept in this film and I didn't believe it could have taken her so long to confess her love to the man of her dreams especially when she does it on the day of his wedding.
'My Best Friend's Wedding' is a fantastic date movie even though it falls victim to the trappings of old fasioned Hollywood movie making in the most sentimental of ways and in many ways this in uncharacteristic of the film's writer (Ronald Bass who won an Oscar for co-writing 1988's 'Rain Man'). The film's director (P.J. Hogan) must have been responsible for this. There is a just ending to this film but it doesn't conclude the way you might think it will and I wish I could believe that someone as attractive as Julia Roberts could stay single until she was three weeks away from her 28th birthday (her age in the film) but women this gorgeous are usually taken long before that. At least the movie is honest enough to relay the fact that in most cases men and women can't have a close platonic relationship without taking things further because as Billy Crystal said in 'When Harry Met Sally' -----> "the sex part always gets in the way".

MPCEmulation¶
-
class
mshoot.
MPCEmulation
(emumod, cfun)¶ Bases:
object
MPC emulation is used to test an MPC strategy in a simulated environment. Two models are required: (1) control model, (2) emulation model.
The control model is used in the optimization. The emulation model is the virtual mock-up of the real system.
The cost function should return a scalar and have the following signature:
def cost(xdf, ydf): # user code here return cost
where xdf is the state data frame and ydf is the output data frame.
Parameters: - emumod – SimModel, emulation model
- cfun – user cost function
-
optimize
(model, inp_ctr, inp_emu, free, ubounds, xbounds, x0, ynominal=None, maxiter=50, step=1, horizon=10, inp_clb=None)¶ Optimize problem using progressive multiple shooting optimizations.
inp_ctr and inp_emu have to have the same index (control and emulation inputs need to be aligned).
If inp_clb is provided with a callback function, then it overrides inp_ctr. The function can be used to provide new inputs for each receding horizon, emulating in example new weather/occupancy forecasts. The callback function takes only one argument index, which is a numpy 1D array with time steps for which the inputs have to be provided, e.g. if index = [300, 600, 900, 1200] is passed to the function, it should return a data frame with index [300, 600, 900, 1200] and columns for all input variables. Since inp_ctr is a required argument, for clarity it is advised to set it to None in cases when inp_clb is provided. See the example examples/mpc_fmi_6.py for how to use inp_clb.
Return:
- u - DataFrame, optimal free inputs
- xctr - DataFrame, control states
- xemu - DataFrame, emulation states
- yemu - DataFrame, emulation outputs
- uhist - list of DataFrames, optimal free inputs per MPC interval
Parameters: - model – SimModel, control model
- inp_ctr – DataFrame, fixed inputs for control model, index with time
- inp_emu – DataFrame, fixed inputs for emulation model, index with time
- free – list, names of free inputs
- ubounds – list of tuples of floats, free input bounds
- xbounds – list of tuples of vectors, state bounds
- x0 – list, initial state
- ynominal – list, nominal values of outputs (for regularization)
- maxiter – int, maximum number of iterations (default 50)
- step – int, MPC re-run step - number of inp rows (default 1)
- horizon – int, opt. horizon - number of inp rows (default 10)
- inp_clb – callback function, see description
Returns: u, xctr, xemu, yemu, uhist

Welcome to KinJector’s documentation!¶
KinJector¶
Inject/eject JSON/YAML data to/from KiCad Board files.
- Free software: MIT license
- Documentation: https://xesscorp.github.io/kinjector
Features¶
- Parameters in one or more JSON or YAML files can be injected into a KiCad PCB file.
- Parameters from a KiCad PCB file can be extracted and stored in a JSON or YAML file.
- The currently-supported set of parameters can control the design rules, net classes, assignment of netclasses to particular nets, plotting options, and (X,Y)/orientation/top-bottom-side position of part footprints.
- Subsets of parameters can be used to restrict the scope of effects upon the PCB.
- A script is provided to allow injection/ejection of JSON/YAML data to/from
a KiCad PCB file. In addition, the
kinjector
module can be used within other Python scripts to manipulate KiCad PCB files.
Installation¶
KinJector needs KiCad’s pcbnew
Python module to run.
For this reason, you’ll probably want to install it in KiCad’s Python environment.
Under Windows, you can do this by opening a terminal and issuing the command:
$ set path=C:\Program Files\kicad\bin;%path%
Then to install KinJector, run this command in your terminal:
$ pip install kinjector
This is the preferred method to install KinJector, as it will always install the most recent stable release. However, if you want the latest features before a stable release is made, you can get that with this command:
$ pip install git+https://github.com/xesscorp/kinjector
Usage¶
Command Line¶
KinJector comes with a command-line script called (appropriately enough) kinjector
.
It can be used in two ways:
- To inject data stored in a JSON or YAML file into a KiCad board file
$ kinjector -from data.json -to test.kicad_pcb
- To extract data from a KiCad board file and store it in a JSON or YAML file
$ kinjector -from test.kicad_pcb -to data.yaml
The data file can contain information on:
- Design rule settings (allowable track widths, via sizes, etc.);
- Enabled board layers and layer visibility;
- Net class definitions;
- Assignments of nets to net classes;
- Plot settings (format, output layers, etc.);
- Part information such as (X,Y) position, angle of orientation, and location on the top or bottom side of the PCB.
The easiest way to comprehend the structure of the data is to extract an example from an existing board and look at the resulting JSON/YAML file as follows:
board:
modules:
D1:
position:
angle: 304.0
side: top
x: 161417004
y: 99187004

- diameter: 800001
drill: 400001
via min diameter: 200001
via min drill size: 300001
You don’t need to specify every field in order to inject data into a board: only the fields you want to change are needed. For example, this YAML file will change the minimum track width to 0.3 mm (300000 nm) and leave the rest of the board unchanged:
board:
settings:
track min width: 300000
As a Package¶
To use the KinJector package in a Python project:
import kinjector
This will give you access to the Board
class that has two methods:
inject(self, data_dict, brd)
: This will inject the data in a dictionary into a KiCadBOARD
object.eject(self, brd)
: This will return a dictionary containing all the data that is currently supported from aBOARD
object.
As an example, the code shown below will extract all the data from a KiCad PCB file and then inject it all back into the same board:
import json
import pcbnew
import kinjector
# Extract info from a KiCad board and store it in a data file.
brd = pcbnew.LoadBoard('test.kicad_pcb')
data_dict = kinjector.Board().eject(brd)
with open('test.json', 'w') as data_fp:
json.dump(data_dict, data_fp, indent=4)
# Inject data from file back into board.
brd = pcbnew.LoadBoard('test.kicad_pcb')
with open('test.json', 'r') as data_fp:
data_dict = json.load(data_fp)
kinjector.Board().inject(data_dict, brd)
brd.Save('test_output.kicad_pcb')
You can also inject data into a board using Python dicts. Just replicate the hierarchical structure and field labels shown above.

Senseless (1998)
Director: Penelope Spheeris Cast: Marlon Wayans, David Spade, Rip Torn, Brad Dourif, Patrick Ewing, Matthew Lillard, Tamara Taylor Written by: Greg Erb, Craig Mazin Producers: Eric L. Gold, David Hoberman Runtime: 88 min. Production Company: Miramax/Dimension Rated R: language, sex
By Nathaniel R. Atcheson<EMAIL_ADDRESS>Marlon Wayans (yet another Wayans brother?) is a pretty funny guy. He seems pretty nice, too. Even though he doesn't have a lot of screen presence, he made me laugh quite a bit as I watched Senseless. And I suppose that this is the point of the film--get us to like Marlon Wayans. Unfortunately, Wayans can't significantly overcome this dopey script. The movie has funny moments, yes, but most of them originate with the profoundly dumb idea on which Senseless is based. The comedy is an excuse for the lame story, but everything would be so much funnier and less painful if this statement were the other way around.
 He tries giving blood four times a day, but this proves tiresome. He does various odd jobs about campus, but none of them seem to pay well. Finally, he agrees to be part of an experiment led by Dr. Wheedon (Brad Dourif). The experiment has Darryl injecting glowing green slime into his buttocks (and we get to see this process several times!). The end result allows Darryl's senses to become hyper-alert.
He can read microscopic typing from hundreds of feet away. He can smell non-existent body odor. He can hear the ticking of a watch ten feet away as if it were church bell in his ear. Once he is able to control his senses (and the rectal itching dies down), he finds that his new heightened senses will be particularly useful to win a coveted accounting job for a big company. His primary competitor for the job is the evil Scott Butler (David Spade, who is totally hilarious here), a Rich Boy who gets everything handed to him by his rich father. Along the way, there is the obligatory love affair with a beautiful woman (Tamara Taylor).
I suppose a pretty good word to describe this film is generic. Aside from Wayans, there's nothing much new here. Not that this is necessarily bad: stock-comedies can be enjoyable, even if they aren't very original. As a story, however, Senseless is particularly bad. The screenplay doesn't even ask me to suspend my disbelief (uhhh, so what are the side effects of this miracle drug?), so I didn't feel inclined to take any of it seriously. Was I supposed to? Well, the film itself takes all the moments with Darryl's family extremely seriously. Most dopey comedies like this require that there be serious moments, even if the tone doesn't match the rest of the film.
This is where director Penelope Spheeris comes in. I remember her work on Wayne's World to be pretty good, and here it's certainly not awful. But scenes within the film clash magnificently with the rest of the film, such as all the subplots revolving around Darryl's pierced-up roommate, Tim (Matthew Lillard from Scream). And in one moment, a strange revelation is made about Janice's heritage, and I was very curious as to why. It provides an interesting sequence in which Wayans fondles Rip Torn...and I suspect that this is the sole reason that this plot detail was included.
And that's what Senseless comes down to. This is not the kind of film one can hate--it's just kind of there. There's no objectionable material (well, I suppose there's some toilet humor). Wayans is funny, Spade is funny, and all of the actors are competent, but the story is here for no other reason than to provide a few funny sequences for Wayans to run through. When the film is over--should you decide to see it--take a step away and just think about how phenomenally absurd the entire thing is. Then ask yourself if you cared as you watched the film. When I ask myself that question, I realize that I didn't care too much. I guess it deserves points for that.
