Welcome to ScalaTion, the Scala-based system for Simulation, Optimization and Analytics.
This system, coded in Scala, supports multi-paradigm simulation modeling including 'tableau', 'event', 'process', 'dynamics', 'dynamics_pde', 'activity' and 'state' oriented models.
Scala is a modern object-oriented, functional programming language that is well-suited for developing simulation engines. It is in the Java family of languages and can call Java code. The inclusion of advanced and functional programming capabilities, makes the code much more concise than Java. ScalaTion also supports optimization and analytics as they nowadays go hand-in-hand with simulation modeling. Some of the algorithms come in both sequential and parallel versions.
The ScalaTion 1.6 version defines multiple .par subpackages that contain parallel versions of sequential algorithms. Future directions include completing the 'scala3d' and 'physics' packages.
As of version 1.6, ScalaTion consists of five subprojects: scalation_mathematics, scalation_statistics, scalation_database, scalation_modeling and scalation_models

ScalaTion is set up to use the Simple Build Tool sbt. ScalaTion 1.6 uses the following five build specification files (one for each module):
$ cd your_project_dir
$ sbt new sbt/scala-seed.g8
$ cd hello
$ mkdir lib
copy jar files from lib
$ cd src/main/scala/example
$ vim Hello.scala
The second time you do this, you will want to use a more appropriate name than hello.

Nexperia joins the GaN FET market for high voltage applications
by Alex McCarthyNexperia has announced its entry into the GaN FET market with the introduction of the 650V GAN063-650WSA, with a gate-source voltage (VGS) of +/-20V and a temperature range of -55 to 175°C. The GAN063-650WSA features a low RDS(on) – down to 60 mΩ – and fast switching for efficiency.
The company is targeting applications including xEV, datacentres, telecom infrastructure, industrial automation and high-end power supplies. Nexperia says its GaN-on-silicon process is highly scalable as wafers can be processed in existing silicon fabrication facilities.
Moreover, the device is available in industry-standard TO-247, allowing customers to benefit from GaN performance in a familiar package.
Toni Versluijs, general manager of Nexperia MOS Business Group says “This is a strategic move for Nexperia into the high voltage area, and we can now deliver technology suitable for xEV power semiconductor applications.”
The automotive sector is a key area of focus for the company, owing to the potential for significant growth over the coming decades.
The GAN063-650WSA GaN FET is the first in a portfolio of GaN devices the company is developing to address the automotive, communication infrastructure and industrial markets.

Genotyping assays for bi-allelic markers (e.g. SNPs) produce signal intensities for the two alleles. 'fitPoly' assigns genotypes (allele dosages) to a collection of polyploid samples based on these signal intensities. 'fitPoly' replaces the older package 'fitTetra' that was limited (a.o.) to only tetraploid populations whereas 'fitPoly' accepts any ploidy level.

IR Learning mode
The Pinscape unit can learn remote control commands through
its IR sensor. To use this feature, you have to set up the
IR receiver, as described in the Build Guide.
After bringing up the IR learning dialog, get your remote
control ready by pointing it at the Pinscape IR sensor. Don't
press any buttons on the remote yet. Click the Learn button
when you're ready. When prompted, press and hold the
remote control key you want Pinscape to learn. The dialog
window will update automatically as soon as Pinscape learns
the code, which usually only takes a second or two.
If the learning process fails, you can click "Try Again"
to give it another go. IR transmissions occasionally
fail due to momentary problems, such as interference
from another light source. If Pinscape refuses to recognize
the code after a couple of tries, though, the remote probably
isn't compatible with the Pinscape hardware or software.
There are two main possibilities:
- If the pulse display at the bottom of the dialog
shows a series of lines, the sensor is properly detecting
the physical IR signal from your remote, but the Pinscape
software doesn't recognize the data format. There are
many IR data formats; the Pinscape software recognizes
about 30 of them, which cover most of the major consumer
electronics companies, but there are many other obscure
protocols that Pinscape doesn't recognize. In this case,
there's hope: the problem is purely a matter of software,
so we might be able to add support for the new protocol
in a future version if you contact the Pinscape developers
and let us know about it. Tell us the make and model of
the TV or other device, and include the contents of the
"Show Raw Data" window.
- If the pulse display at the bottom of the dialog is
completely blank, the sensor isn't receiving any signal
at all from the remote. This might mean that your remote
is using an IR wavelength or modulation frequency that
the Pinscape sensor can't receive. Unfortunately, this
type of incompatibility is difficult to solve, because
it would require replacing the sensor with one that can
work with your remote. But replacing the sensor could
create a whole separate problem, in that the Pinscape
software is only designed to work with the recommended
sensor type. Before giving up, you might want to
double-check that the sensor itself is working, by
trying a remote from different manufacturer.

Click the button to animate the div with a number of different properties.
Animates a div's left property with a relative value. Click several times on the buttons to see the relative animations queued up
The first button shows how an unqueued animation works. It expands the div out to 90% width while the font-size is increasing. Once the font-size change is complete, the border animation will begin. The second button starts a traditional chained animation, where each animation will start once the previous animation on the element has completed.
Animates the first div's left property and synchronizes the remaining divs, using the step function to set their left properties at each stage of the animation.

Search Inside Yourself: The Unexpected Path to Achieving Success, Happiness(and World Peace)
Chapter 8 - Leadership and Social Skills
What is your experience of compassionate and leadership?
Compassionate
I have had several years on this earth learning and although I thought myself to be naturally compassionate. This skill can sometimes be difficult to maintain and from my understanding mindfulness has help me to understand myself and better control my emotions. Through my journey of mindfulness I have taken to the time to center myself and everything I have experienced up until now has been beneficial.
Leadership
Having worked in a few leadership roles in the past I can certainly understand being compassionate, through cognitive, affective and motivational is an important valuable skill to master. I learned alot things about myself while in these work roles about relating to other people as well as ensuring I thought about what I said and how it would affect others.
Do the multiplying goodness meditation. How did you find it?
Everytime I meditate I enjoy the experience more, so after this exercise I knew I would feel great. It was a struggle to think of everyone as good because I have long known it a character flaw of mine and it has got into trouble many times. Thinking about goodness and everyone being good, when I knew this to be false. I found it was a challenege, so I had to say it aloud.
Do the Tonglen meditation. How did you find it?
From the perspective of a mountain the experience was illuminating and different. Taking in negativity and thinking about it. However, exhaling it all out was easy and far more relieving. Using visualisation is not a new concept. After watching another channel four story last week about the crisis in Myanmar so imagine human suffering and pain was manageable to understand. In return having alot of positive quotes around the house and keep a vision board that I assess and look at often. What I learned was taking on negative thought was only made easy because I knew it would end in positive thoughts.
How does the SCARF model apply to your Phase 0 experience so far? How will it apply to bootcamp?
Status, - I believe the completion of this course will open new doors to new career. I have also found it feels good to tell friends and family about this exciting new career path.
Certainty - As the chapter suggests, uncertainty generates “error responses” in the brain that cannot be ignored until they are resolved. My main fear is that I would not remember the knowledge and I knew that I could not retain it all. My certainty came from knowing that I would learn more as I went through the process and I have accepted this as apart of my learning process.
Autonomy - There were countless times when I felt helpless and lost. I felt this was apart of the learning process for me. To understand how I manage stress and trouble shoot through it and come out the otherside wiser.
Relatedness - It was great being able to connect with other students at EDA. I did relate well with others as we shared each others experiece. This made me feel at ease knowwing other students had experience some of the same emotions and concerns.
Fairness - I strongly believe that although I disapline with fairness, I have alway believed also that sometimes life is not unfair. Through my lifetime I have learned to endure some hardships as I am sure we all have. This has made me more resilent and tolerant.
Have a difficult conversation. How did it go?
I recently had to make a call I was not looking forward to making. I knew the discussion was going to be very difficult. After running through the conversation through my head several times and I felt prepared. Once I was ready and careful with the words I used and offered my thanks when the other person replied. I was happy when the situation was resolved and apologies were shared all around. Peace was again restored.

Here you get a comprehensive overview on password theory. If you only want to get a feeling for the security of your own password, then use the dialog Password Quality Meter.
The importance of passwordsPasswords are important for all IT systems that offer interfaces for user access. Particularly, this includes PCs in the private and commercial sector as well as services like e-mail or online banking. In these cases the log-on is usually done by entering a user name and the according password.
The IT system can only judge from the entered data whether there is a legal access or not. Consequently, if an unauthorized person acquires a valid combination of user name and password, he can apparently legal log-on to the IT system, eavesdrop or manipulte data in a harming way.
According to this, the security of passwords is an important principle for the security of IT systems.
The security of passwordsEssentially, two factors need to be kept in mind in order to keep the security of passwords:
a) First of all, a secure password should be chosen. A secure password is a password that cannot easily be guessed. Thus, words out of dictionaries never make good passwords. A lot of other words are no good passwords either. For example common names, variations of the respective user name or other simple passwords. With the help of certain programs these passwords can be guessed within seconds.
The dialog Passwort Quality Meter can give you a indication for the security of your password.
b) The secure storage of passwords also plays a big role for password security. On the one hand, this means one should never write his passwords down in order to prevent unauthorized access. On the other hand, this includes technical measures like hash functions or PKCS#5 when passwords are transmitted over public networks or stored in password files.
Password length, password space and password entropyIf you factor out inappropriate handling and storage of passwords, then the security of a password depends on the length of the password, the size of the password space and the entropy of the password.
The length of a password has a huge influence on its security. Short passwords can easily be guessed, so in turn a short password is a bad password. The longer a password, the better.
That password length is a very important aspect of password security is stressed in an article by Roger A. Grimes on password cracking (2007). Basically, Grimes claims that, for the security of passwords, length is much more important than complexity because real complexity is hard to accomplish.
The size of the password space is the amount of passwords that can be created with all available characters (the alphabet). Assume you have an alphabet of 52 letters (upper- and lowercase) as well as ten digits, then the password space consists of 62^8, that is around 200 trillion passwords. If you increase the size of the alphabet with 10 more characters (for example special characters), the password space grows to more than three times of its size. The bigger the password space, the better.
According to an article in the magazine PC-WELT (issue 08/2007), an up-to-date computer can guess around 25 million passwords per second. Imagine the password space consists of roughly 2 billion passwords (which is the case for a password length of only six characters and an alphabet consisting of lower-case letters and ten digits). In such a scenario it would take less than 90 seconds to search through the complete password space.
For comparison only: If you have a password space of around 200 trillion passwords (see above), a complete search through the password space would already take more than 100 days. Actually, such a password space should be considered big enough, especially if you change your password on a regular basis like every three months (for example, this is enforced in bigger companies). But keep in mind that attacks against passwords can be parallelized, and certain institutions (intelligence) command way more computational power than the average computer user.
The password entropy indicates how "randomly" a password is chosen out of the given password space. Based on certain statistical assumptions you can exactly determine the entropy of a password.


Amaechi congratulates Bayelsa Governor-elect, says victory opens APC’s future inroad in South South
by The Eagle OnlineMinister of Transportation, Chibuike Amaechi, on Tuesday congratulated David Lyon, the Governor-elect of Bayelsa.
Amaechi told News Agency of Nigeria in Abuja that the victory was a testimony of President Muhammadu Buhari’s administrative transformations.
He lauded the APC-led Federal Government for genuinely working to alleviate poverty and tackle litany of economic challenges confronting the nation, which according to him, is yielding results.
The minister, who is also an APC chieftain in the South-South, described the victory as the beginning of APC’s future glories in the geopolitical zone.
“We thank God and congratulations to all the victors,’’ Amaechi said.
NAN reports that the APC gubernatorial candidate, David Lyon, won in six of the state’s eight local government areas.
He defeated his closest rival, Senator Douye Diri of the Peoples Democratic Party, who captured only two local governments.
The Chief Returning Officer, Prof. Faraday Orumwense, declared Lyon winner, having polled 352,552 votes to defeat Diri, who polled 143,172 votes.
The six local government areas won by the APC are Brass, Nembe, Ogbia, Southern Ijaw, Ekeremor and Yenagoa while the PDP won in the Sagbama and Kolokuma/Opokuma local government areas.

Questions welcome!
This is pretty low-level stuff; if you have a question, chances are everyone else does too!
Mozilla Firefox/SpiderMonkey hacker for 8 years
Member of WebAssembly W3C Community Group
An emerging standard which defines:
Multiple valid ways to look at WebAssembly:
Depends on where you are coming from
Not a programming language
Compile from programming languages
As close to real CPUs as safety/portability allow
WebAssembly doesn't change the security model of the Web
Pointers are checked indices, not raw addresses
Memory access is like JS array access: out-of-bounds throws
Changing browser/version/device shouldn't break things
Just like upgrading your x86 CPU shouldn't break things
So WebAssembly specifies everything*
| WebAssembly | x86/x64 | ARM/ARM64 | |
|---|---|---|---|
i32.add |
↦ | addl |
ADD |
call |
↦ | call |
BL |
i32.load |
↦ | check + mov |
check + LDR |
| infinite stack/locals | ↦ | 8/16 registers | 16/32 registers |
asm.js is an extraordinarily optimizable, low-level subset of JavaScript that can be compiled from languages like C/C++.
Because it's just JavaScript, runs well on all browsers today.
Special optimizations added to Firefox, Edge and Chrome.
Safari includes asm.js in their JetStream benchmark.
How do you get asm.js?
C/C++ ⇒ clang/LLVM ⇒ Emscripten ⇒ asm.js
| 2009 - 2012 |
Mozilla Research experiments: Emscripten: C/C++ to JS compiler/toolchain asm.js: optimize Emscripten-style output |
| 2013 - 2014 | Published asm.js subset, shipped optimizations in Firefox, demonstrated on large game engines |
| 2015 - 2016 |
Other browsers add optimizations Adobe, AutoDesk, Epic, Facebook, Mega, Unity, and more shipping with Emscripten/asm.js Cross-browser work begins on WebAssembly |
Why are developers using asm.js?
Why wasn't asm.js enough?
WebAssembly as binary encoding of asm.js (with tweaks)
| asm.js | WebAssembly | |
|---|---|---|
(x+y)|0 |
↦ | i32.add |
| ☹ | ↦ | i64.add |
f()|0 |
↦ | call |
HEAP32[i>>2]|0 |
↝ | i32.load |
raw: WebAssembly is ~42% smaller
gzipped: WebAssembly is ~23% smaller
Decoding WebAssembly ~10x faster than parsing JS
Ability to efficiently load large code +
predictable near-native performance =
Powerful JavaScript library-building tool
What sort of libraries? Today, using asm.js:
Tomorrow: Web Frameworks!
What?!! But it's all DOM and strings and stuff!
Not anymore: virtual DOM, reconciliation, bytecode VMs, ...
WebAssembly is being specified and shipped iteratively
What's released today is the Minimum Viable Product (MVP)
There is a lot more to do: standard and toolchain
Speculative features are marked with ☃
Today, WebAssembly primarily compiled from C/C++:
C/C++ ⇒ clang/LLVM ⇒ Emscripten ⇒ WebAssembly
Ongoing work on:
Start with some C code:
// demo.c
MODULE_EXPORT
int add(int lhs, int rhs) {
return lhs + rhs;
}
then compile to wasm
:
☃ clang-wasm demo.c -o demo.wasm
Render the binary as text:
$ wasm2wat demo.wasm | less
(module
(func (export "add") (param i32 i32) (result i32)
get_local 0
get_local 1
i32.add
)
)
Tour of opcodes out of scope, see draft spec
Compile the .wasm
using JS WebAssembly
API
fetch('demo.wasm').then(response =>
response.arrayBuffer()
).then(bytecode =>
WebAssembly.instantiate(bytecode)
).then(({instance}) =>
alert("1 + 2 = " + instance.exports.add(1, 2));
);
wasm://
URL appearStandardized and coming soon:
WebAssembly.instantiate(fetch('demo.wasm')).then(({instance}) =>
alert("1 + 2 = " + instance.exports.add(1, 2));
);
Allows browser to do streaming and caching
☃ ES Module integration:
WebPack integration starting
Lot more work to do here to integrate with modular workflow!
WebAssembly can call JavaScript too!
// main.c
// Think: import {printInt} from 'logger';
extern MODULE_IMPORT("logger") void printInt(int);
int main() {
printInt(42);
}
JS functions are imported (just as with an ES Module)
☃ With ES Module integration, we could write:
// logger.js
export var printInt = i => console.log(i);
Today, pass in JS function using the WebAssembly
API:
function printInt(i) { console.log(i) }
WebAssembly.instantiate(fetch('main.wasm'), {logger:{printInt}});
What we really want to see is the source language
Source Maps actually map naturally onto WebAssembly
Still need to add mappings for variable names
More work to do here...
What APIs look like on a traditional VM:
The Web started out different:
But the Web has changed a lot since then
and is starting to resemble a traditional virtual platform
... with some special "Webby" properties like:
So where does WebAssembly fit in?
Today, WebAssembly only gets to Web APIs by "thunking" through JavaScript
Emscripten maps common C/C++ interfaces to Web APIs:
#include <SDL/SDL.h>
#include <stdio.h>
int main(int argc, char **argv) {
SDL_Init(SDL_INIT_VIDEO);
SDL_Surface *s = SDL_SetVideoMode(200, 200, 32, SDL_HWSURFACE);
SDL_Rect rect = { 50, 50, 100, 100 };
SDL_FillRect(s, &rect, 0xffff0000);
printf("Done!\n");
return 0;
}
Compiled by Emscripten with:
emcc -O2 test.c -o test.html
Which produces a default HTML harness:
☃ In the future, import and call Web APIs directly from WebAssembly
Currently, WebAssembly only has linear memory
Great if your language has a low-level memory model (C++, Rust, FORTRAN)
But if your language has GC:
To provide first-class support for GC languages, WebAssembly needs direct GC access
☃ Goal: add low-level GC primitives to avoid baking in one language's class model
☃ Goal: share GC heap with JS, allow objects/strings/values to flow back and forth
Follow on GitHub GC proposal repo
☃☃ So what could you do with GC support? ☃☃
Need even more features in WebAssembly to run dynamic languages efficiently:
dynamic
/any
-typePrecedent with invokedynamic
in the JVM
☃☃ But this is all rather far off ☃☃
No. Why?
In fact, WebAssembly may have quite the opposite effect:
If you're going to target WebAssembly and your app needs a scripting language, JS is a natural choice...
Sure, if you want to go slower
...theoretically you could get a startup win by shipping your own bytecode + JS interpreter...

firewalld 101
20 November 2015
firewalld provides a dynamically managed firewall with support for network/firewall zones to define the trust level of network connections or interfaces. It has support for IPv4, IPv6 firewall settings and for ethernet bridges and has a separation of runtime and permanent configuration options. It also supports an interface for services or applications to add firewall rules directly.
The two important concepts of firewalld is zones and services.
A zone defines the trust level of the interface used for a connection. There are several pre-defined zones provided by firewalld.zone.
A service can be a list of local ports and destinations and additionally also a list of firewall helper modules automatically loaded if a service is enabled. Service configuration options and generic information about services are described in firewalld.service. The use of predefined services makes it easier for the user to enable and disable access to a service.
$ firewall-cmd --get-zones
block dmz drop external home internal public trusted work
In order from least trusted to most trusted, the pre-defined zones within firewalld are:
| Zone | Definition |
|---|---|
| drop | The lowest level of trust. All incoming connections are dropped without reply and only outgoing connections are possible |
| block | Similar to the above, but instead of simply dropping connections, incoming requests are rejected with an icmp-host-prohibited or icmp6-adm-prohibited message |
| public | Represents public, untrusted networks. You don't trust other computers but may allow selected incoming connections on a case-by-case basis |
| external | External networks in the event that you are using the firewall as your gateway. It is configured for NAT masquerading so that your internal network remains private but reachable |

Changing the zone of your interface permanently
Interfaces will always revert to the default zone if they do not have an alternative zone defined within their configuration. On CentOS, these configurations are defined within the /etc/sysconfig/network-scripts
directory with files of the format ifcfg-interface.
$ firewall-cmd --list-all
public (default, active)
interfaces: enp0s3
sources:
services: dhcpv6-client ssh
ports:
masquerade: no
forward-ports:
icmp-blocks:
rich rules:
You will see from the output that I have a public zone applied to enp0s3. I will then open /etc/sysconfig/network-scripts/ifcfg-enp0s3 to add zone at the bottom.
TYPE="Ethernet"
BOOTPROTO="dhcp"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"

UUID="d51651b7-8f3a-4ee0-bee4-3b58f9e356b7"
DEVICE="enp0s3"
ONBOOT="yes"
ZONE=home
To implement your changes, you'll have to restart the network service, followed by the firewall service:
$ sudo systemctl restart network.service
$ sudo systemctl restart firewalld.service
Adjusting the Default Zone
You can change the default zone with the --set-default-zone=
parameter. This will immediately change any interface that had fallen back on the default to the new zone.
$ sudo firewall-cmd --set-default-zone=home
success
$ firewall-cmd --list-all
home (default, active)
interfaces: enp0s3
sources:
services: dhcpv6-client ipp-client mdns samba-client ssh
ports:
masquerade: no
forward-ports:
icmp-blocks:
rich rules:
Adding a Service to your Zones
The easiest method is to add the services or ports you need to the zones you are using. Again, you can get a list of the available services with the --get-services option.
$ firewall-cmd --get-services
RH-Satellite-6 amanda-client bacula bacula-client dhcp dhcpv6 dhcpv6-client dns ftp high-availability
http https imaps ipp ipp-client ipsec kerberos kpasswd ldap ldaps libvirt libvirt-tls mdns mountd
ms-wbt mysql nfs ntp openvpn pmcd pmproxy pmwebapi pmwebapis pop3s postgresql proxy-dhcp radius
rpc-bind samba samba-client smtp ssh telnet tftp tftp-client transmission-client vnc-server wbem-https
You can enable a service for a zone using the --add-service= parameter. The operation will target the default zone or whatever zone is specified by the --zone= parameter. By default, this will only adjust the current firewall session. You can adjust the permanent firewall configuration by including the --permanent flag.
$ sudo firewall-cmd --zone=home --add-service=http
success
$ firewall-cmd --zone=home --list-services
dhcpv6-client http ipp-client mdns samba-client ssh
Once you have tested that everything is working as it should, you will probably want to modify the permanent firewall rules so that your service will still be available after a reboot.
$ sudo firewall-cmd --zone=home --permanent --add-service=http
success
$ sudo firewall-cmd --zone=home --permanent --list-services
dhcpv6-client http ipp-client mdns samba-client ssh
Opening a Port for your Zones
The easiest way to add support for your specific application is to open up the ports that it uses in the appropriate zone(s). This is as easy as specifying the port or port range, and the associated protocol for the ports you need to open.
For instance, if our application runs on port 4000 and uses TCP, we could add this to the "home" zone for this session using the --add-port= parameter. Protocols can be either tcp or udp.
$ sudo firewall-cmd --zone=home --add-port=4000/tcp
After testing, you would likely want to add these to the permanent firewall.
$ sudo firewall-cmd --zone=home --permanent --add-port=4000/tcp
success
$ sudo firewall-cmd --zone=home --permanent --list-ports
4000/tcp
Defining a Service
Opening ports for your zones is easy, but it can be difficult to keep track of what each one is for. If you ever decommission a service on your server, you may have a hard time remembering which ports that have been opened are still required. To avoid this situation, it is possible to define a service.
Services are simply collections of ports with an associated name and description. Using services is easier to administer than ports, but requires a bit of upfront work. The easiest way to start is to copy an existing script /usr/lib/firewalld/services
to the /etc/firewalld/services
directory
where the firewall looks for non-standard definitions.
$ sudo cp /usr/lib/firewalld/services/http.xml /etc/firewalld/services/webrick.xml
$ sudo vi /etc/firewalld/services/webrick.xml
<?xml version="1.0" encoding="utf-8"?>
<service>
<short>webrick</short>
<description>Ruby's default HTTP server.This is single threaded which means can only process single request at a time.</description>
<port protocol="tcp" port="4000"/>
</service>
$ sudo firewall-cmd --reload
success
$ firewall-cmd --get-services
RH-Satellite-6 amanda-client bacula bacula-client dhcp dhcpv6 dhcpv6-client dns ftp high-availability
http https imaps ipp ipp-client ipsec kerberos kpasswd ldap ldaps libvirt libvirt-tls mdns mountd ms-wbt
mysql nfs ntp openvpn pmcd pmproxy pmwebapi pmwebapis pop3s postgresql proxy-dhcp radius rpc-bind samba
samba-client smtp ssh telnet tftp tftp-client transmission-client vnc-server wbem-https webrick
Creating Your Own Zones
While the predefined zones will probably be more than enough for most users, it can be helpful to define your own zones that are more descriptive of their function.
When adding a zone, you must add it to the permanent firewall configuration. You can then reload to bring the configuration into your running session. For instance, I could create a zone by typing
$ sudo firewall-cmd --permanent --new-zone=
success
$ sudo firewall-cmd --permanent --get-zones
block dmz drop external home internal public publicweb trusted work

When it comes to digital design, the lines between functionality, aesthetics, and psychology are inseparably blurred. Without the constraints of the physical world, there’s no natural form to fall back on, and every bit of constraint and affordance must be introduced intentionally. Good design makes a product useful.

Interaction with real or virtual devices is performed by the Communicator application, which acting as a master or a slave, polls data and sends commands to devices. All the devices are bound to communication lines. Communication lines are independent of each other and work in parallel.
The user interface of Communicator, designed for configuration, is built into the Administrator application. Communicator is configured as part of a project.
Figure 1 shows an example of the main communication line parameters. A communication channel determines physical interface or network protocol which is used for data exchange with devices. The following communication channels are supported: Serial port, TCP client, TCP server and UDP. In some cases, if the interaction with devices is implemented by a device driver, communication channel should be undefined (e.g., the OPC driver).
If sending commands to devices is not required, it is recommended to untick the Commands enabled checkbox due to safety reasons.
Figure 1. Main communication line parameters
Figure 2. Request sequence
Communication order and request parameters are set on the Request Sequence page (see Figure 2).
If the Active checkbox on the Main Parameters page is unset, the corresponding communication line is disabled, and no requests are performed. If the Active checkbox in the Selected Device group box is unset, communication with that device is disabled.
The Bound to Server checkbox on the Main Parameters page allows to switch on or off sending the communication line data to Server. The Bound to Server checkbox in the Selected Device group box has the similar purpose, but applied only for the device. If the Interact with Server checkbox on the Common Parameters page of the Communicator settings is unset, any interaction between Communicator and Server is disabled. These options are useful for testing new devices being connected to the system.
If the Time and Period parameters of a device are equal to zero, the device is requested cyclically. If the Time parameter is greater than zero and Period is zero, the device is requested once a day in the specified time. If Period is greater than zero, the device is requested periodically starting at the specified time. The Timeout field defines how long to wait an answer from the device after a request. The Delay field defines a delay after each request to the device. Command line may contain additional parameters described in documentation of a device driver.
To reset request parameters of the selected device to the default values, click the Reset button. To open the device properties form, if it is supported by a driver of the selected device, click the Properties button or use a popup menu of the project explorer. To set global properties for a device type, choose the Drivers page, select the device driver and click the Properties button if the button is enabled.
To import communication lines and devices from the configuration database to the Communicator settings, right-click the Communication Lines node or a node of a specific communication line in the project explorer and select the Import item in the context menu. The import form is shown in Figure 3.
Figure 3. Import Communicator settings
The settings synchronization feature (see Figure 4) is also run using the communication line context menu. Synchronization allows to update the parameters of existing communication lines and devices according to the configuration database, however, the parameters entered manually may be lost.
