Making a VR app in three.js is pretty simple.  If you think about it a few things about WebXR should be clear. Which way the camera is pointing is supplied by the VR system itself since the user turns their head to choose a direction to look. Similarly the field of view and aspect will be supplied by the VR system since each system has a different field of view and display aspect.
Let's take an example from the article on making a responsive webpage and make it support VR.
Before we get started you're going to need a VR capable device like an Android smartphone, Google Daydream, Oculus Go, Oculus Rift, Vive, Samsung Gear VR., an iPhone with a WebXR browser.
Next, if you are running locally you need to run a simple web server like is covered in the article on setting up.
If the device you are using to view VR is not the same computer you're running on you need to serve your webpage via https or else the browser will not allow using the WebXR API. The server mentioned in the article on setting up called Servez has an option to use https. Check it and start the server.
The note the URLs. You need the one that is your computer's local ipaddress.
It will usually start with 192
, 172
or 10
. Type that full address, including the https://
part
into your VR device's browser. Note: Your computer and your VR device need to be on the same local network
or WiFi and you probably need to be on a home network. note: Many cafes are setup to disallow this kind of
machine to machine connection.
You'll be greeted with an error something like the one below. Click "advanced" and then click proceed.
Now you can run your examples.
If you're really going to do WebXR development another thing you should learn about is remote debugging so that you can see console warnings, errors, and of course actually debug your code.
If you just want to see the code work below you can just run the code from this site.
The first thing we need to do is include the VR support after including three.js
import * as THREE from 'three'; +import {VRButton} from 'three/addons/webxr/VRButton.js';
Then we need to enable three.js's WebXR support and add its VR button to our page
function main() { const canvas = document.querySelector('#c'); const renderer = new THREE.WebGLRenderer({antialias: true, canvas}); + renderer.xr.enabled = true; + document.body.appendChild(VRButton.createButton(renderer));
We need to let three.js run our render loop. Until now we have used a
requestAnimationFrame
loop but to support VR we need to let three.js handle
our render loop for us. We can do that by calling
WebGLRenderer.setAnimationLoop
and passing a function to call for the loop.
function render(time) { time *= 0.001; if (resizeRendererToDisplaySize(renderer)) { const canvas = renderer.domElement; camera.aspect = canvas.clientWidth / canvas.clientHeight; camera.updateProjectionMatrix(); } cubes.forEach((cube, ndx) => { const speed = 1 + ndx * .1; const rot = time * speed; cube.rotation.x = rot; cube.rotation.y = rot; }); renderer.render(scene, camera); - requestAnimationFrame(render); } -requestAnimationFrame(render); +renderer.setAnimationLoop(render);
There is one more detail. We should probably set a camera height that's kind of average for a standing user.
const camera = new THREE.PerspectiveCamera(fov, aspect, near, far); +camera.position.set(0, 1.6, 0);
and move the cubes up to be in front of the camera
const cube = new THREE.Mesh(geometry, material); scene.add(cube); cube.position.x = x; +cube.position.y = 1.6; +cube.position.z = -2;
We set them to z = -2
since the camera will now be at z = 0
and
camera defaults to looking down the -z axis.
This brings up an extremely important point. Units in VR are in meters. In other words One Unit = One Meter. This means the camera is 1.6 meters above 0. The cube's centers are 2 meters in front of the camera. Each cube is 1x1x1 meter large. This is important because VR needs to adjust things to the user in the real world. That means we need the units used in three.js to match the user's own movements.
And with that we should get 3 spinning cubes in front of the camera with a button to enter VR.
I find that VR works better if we have something surrounding the camera like room for reference so let's add a simple grid cubemap like we covered in the article on backgrounds. We'll just use the same grid texture for each side of the cube which will give as a grid room.
const scene = new THREE.Scene(); +{ + const loader = new THREE.CubeTextureLoader(); + const texture = loader.load([ + 'resources/images/grid-1024.png', + 'resources/images/grid-1024.png', + 'resources/images/grid-1024.png', + 'resources/images/grid-1024.png', + 'resources/images/grid-1024.png', + 'resources/images/grid-1024.png', + ]); + scene.background = texture; +}
That's better.
Note: To actually see VR you will need a WebXR compatible device. I believe most Android Phones can support WebXR using Chrome or Firefox. For iOS you might be able to use this WebXR App though in general WebXR support on iOS is unsupported as of May 2019.
To use WebXR on Android or iPhone you'll need a VR Headset for phones. You can get them for anywhere from $5 for one made of cardboard to $100. Unfortunately I don't know which ones to recommend. I've purchased 6 of them over the years and they are all of varying quality. I've never paid more than about $25.
Just to mention some of the issues
Do they fit your phone
Phones come in a variety of sizes and so the VR headsets need to match. Many headsets claim to match a large variety of sizes. My experience is the more sizes they match the worse they actually are since instead of being designed for a specific size they have to make compromises to match more sizes. Unfortunately multi-size headsets are the most common type.
Can they focus for your face
Some devices have more adjustments than others. Generally there are at most 2 adjustments. How far the lenses are from your eyes and how far apart the lenses are.
Are they too reflective
Many headsets of a cone of plastic from your eye to the phone. If that plastic is shinny or reflective then it will act like a mirror reflecting the screen and be very distracting.
Few if any of the reviews seem to cover this issue.
Are the comfortable on your face.
Most of the devices rest on your nose like a pair of glasses. That can hurt after a few minutes.  Others have a 3rd strap that goes over your head. These may or may not help keep the device at the right place.
It turns out for most (all?) devices, you eyes need to be centered with the lenses. If the lenses are slightly above or below your eyes the image gets out of focus. This can be very frustrating as things might start in focus but 45-60 seconds later the device has shifted up or down 1 millimeter and you suddenly realize you've been struggling to focus on a blurry image.
Can they support your glasses.
If you wear eye glasses then you'll need to read the reviews to see if a particular headset works well with eye glasses.
I really can't make any recommendations unfortunately. Google has some cheap recommendations made from cardboard some of them as low as $5 so maybe start there and if you enjoy it then consider upgrading. $5 is like the price of 1 coffee so seriously, give it try!
There are also 3 basic types of devices.
3 degrees of freedom (3dof), no input device
This is generally the phone style although sometimes you can buy a 3rd party input device. The 3 degrees of freedom mean you can look up/down (1), left/right(2) and you can tilt your head left and right (3).
3 degrees of freedom (3dof) with 1 input device (3dof)
This is basically Google Daydream and Oculus GO
These also allow 3 degrees of freedom and include a small controller that acts like a laser pointer inside VR. The laser pointer also only has 3 degrees of freedom. The system can tell which way the input device is pointing but it can not tell where the device is.
6 degrees of freedom (6dof) with input devices (6dof)
These are the real deal haha. 6 degrees of freedom means not only do these device know which way you are looking but they also know where your head actually is. That means if you move from left to right or forward and back or stand up / sit down the devices can register this and everything in VR moves accordingly. It's spookily and amazingly real feeling. With a good demo you'll be blown away or at least I was and still am.
Further these devices usually include 2 controllers, one for each hand and the system can tell exactly where your hands are and which way they are oriented and so you can manipulate things in VR by just reaching out, touching, pushing, twisting, etc...
6 degree of freedom devices include the Vive and Vive Pro, the Oculus Rift and Quest, and I believe all of the Windows MR devices.
With all that covered I don't for sure know which devices will work with WebXR.
I'm 99% sure that most Android phones will work when running Chrome. You may
need to turn on WebXR support in about:flags
. I also know Google
Daydream will also work and similarly you need to enable WebXR support in
about:flags
. Oculus Rift, Vive, and Vive Pro will work via
Chrome or Firefox. I'm less sure about Oculus Go and Oculus Quest as both of
them use custom OSes but according to the internet they both appear to work.
Okay, after that long detour about VR Devices and WebXR there's some things to cover
Supporting both VR and Non-VR
AFAICT, at least as of r112, there is no easy way to support
both VR and non-VR modes with three.js. Ideally
if not in VR mode you'd be able to control the camera using
whatever means you want, for example the OrbitControls
,
and you'd get some kind of event when switching into and
out of VR mode so that you could turn the controls on/off.
If three.js adds some support to do both I'll try to update this article. Until then you might need 2 versions of your site OR pass in a flag in the URL, something like
https://mysite.com/mycooldemo?allowvr=true
Then we could add some links in to switch modes
 <canvas id="c"></canvas> +
 + Allow VR + Use Non-VR Mode +

and some CSS to position them
body { margin: 0; } #c { width: 100%; height: 100%; display: block; } +.mode { + position: absolute; + right: 1em; + top: 1em; +}
in your code you could use that parameter like this
function main() { const canvas = document.querySelector('#c'); const renderer = new THREE.WebGLRenderer({antialias: true, canvas}); - renderer.xr.enabled = true; - document.body.appendChild(VRButton.createButton(renderer)); const fov = 75; const aspect = 2; // the canvas default const near = 0.1; const far = 5; const camera = new THREE.PerspectiveCamera(fov, aspect, near, far); camera.position.set(0, 1.6, 0); + const params = (new URL(document.location)).searchParams; + const allowvr = params.get('allowvr') === 'true'; + if (allowvr) { + renderer.xr.enabled = true; + document.body.appendChild(VRButton.createButton(renderer)); + document.querySelector('#vr').style.display = 'none'; + } else { + // no VR, add some controls + const controls = new OrbitControls(camera, canvas); + controls.target.set(0, 1.6, -2); + controls.update(); + document.querySelector('#nonvr').style.display = 'none'; + }
Whether that's good or bad I don't know. I have a feeling the differences between what's needed for VR and what's needed for non-VR are often very different so for all but the most simple things maybe 2 separate pages are better? You'll have to decide.
Note for various reasons this will not work in the live editor on this site so if you want to check it out click here. It should start in non-VR mode and you can use the mouse or fingers to move the camera. Clicking "Allow VR" should switch to allow VR mode and you should be able to click "Enter VR" if you're on a VR device.
Deciding on the level of VR support
Above we covered 3 types of VR devices.
You need to decide how much effort you're willing to put in to support each type of device.
For example the simplest device has no input. The best you can generally do is make it so there are some buttons or objects in the user's view and if the user aligns some marker in the center of the display on those objects for 1/2 a second or so then that button is clicked. A common UX is to display a small timer that will appear over the object indicating if you keep the marker there for a moment the object/button will be selected.
Since there is no other input that's about the best you can do
The next level up you have one 3DOF input device. Generally it can point at things and the user has at least 2 buttons. The Daydream also has a touchpad which provides normal touch inputs.
In any case if a user has this type of device it's far more comfortable for the user to by able to point at things with their controller than it is to make them do it with their head by looking at things.
A similar level to that might be 3DOF or 6DOF device with a game console controller. You'll have to decide what to do here. I suspect the most common thing is the user still has to look to point and the controller is just used for buttons.
The last level is a user with a 6DOF headset and 2 6DOF controllers. Those users will find an experience that is only 3DOF to often be frustrating. Similarly they usually expect to be able to virtually manipulate things with their hands in VR so you'll have to decide if you want to support that or not.
As you can see getting started in VR is pretty easy but actually making something shippable in VR will require lots of decision making and design.
This was a pretty brief intro into VR with three.js. We'll cover some of the input methods in future articles.

Let's look through history.
"if every instrument could accomplish its own work, obeying or anticipating the will of others...chief workmen would not want servants, nor masters slaves." Here Aristotle proclaims on of the first worries of mass unemployment.
"Consider thou what the invention could do to my poor sub-jects. It would assuredly bring to them ruin by depriving them of employment, thus making them beggars." Even back in the 1500's people worried about technology causing unemployment.
When the Cotton Gin was invented, thousands of Cotton workers became unemployed. This unemployment is called structural unemployment - when workers just do not have the skills for the job. In the long-run, structural unemployment goes away as seen by the cotton gin not causing long run unemployment.
While other countries had strict regulations, Britain's lassie-faire approach to technology allowed them to take an early lead in the industrial revolution. This is an example of a countries lack of worries about technology bringing them ultimate success.
In the leadup to the great depression, unemployment among rural workers had begun to increase as technologies like tractors started to automate the farming process. However, in the long run this unemployment went away, and farm technology only bettered the world.
As technological development explodes, people begin to become more and more worried about how robots and computers will affect jobs. However, technology companies have only helped grow GDP and raise global welfare. Yet, income inequality has grown as production power goes to the top. Policy needs to be put in place to prevent this.
Coming technologies like self-driving cars and machine learning are only expected to increase worries about unemployment. However, mainstream economists only predict that they will better people on average. Technology jobs will become more common, and people will work less in manual labor and such.
Prof. Vinge proposes that Artificial Intelligence will get so powerful that humans will no longer need to work. This is an idea called the singularity. Theoriticans are skeptical that this could happen. However, in the case that it does, public policy needs to be ready to adapt.

GUI.GetVersion
Syntax
GUI.GetVersion : int
Description
Returns the current version of the GUI Procedure Library. Because the GUI Procedure Library is expected to grow, new versions will probably be made available at our web site http://www.holtsoft.com/turing. If you wish to use features that do not appear in earlier versions of the library, you can have your program check that the current available version meets the programs needs. GUI.GetVersion returns an integer from 100 - 999 and is read as 1.00 to 9.99.
Example
The following program fragment immediately exits if OOT does not support version 1.1 of the GUI Procedure Library
import GUI in "%oot/lib/GUI"
if GUI.GetVersion < 110 then
put "You must update to at least version 1.1 of the"
put "GUI Procedure Library to use this program."
return
end if
Details
In version 1.00 (shipped with MacOOT 1.5), GUI.GetVersion did not exist.
Status
Exported qualified.
This means that you can only call the function by calling GUI.GetVersion, not by calling GetVersion.

Abstract: Understanding the connotation of words plays an important role in interpreting subtle shades of sentiment beyond denotative or surface meaning of text, as seemingly objective statements often allude nuanced sentiment of the writer, and even purposefully conjure emotion from the readers’ minds. The focus of this paper is drawing nuanced, connotative sentiments from even those words that are objective on the surface, such as “intelligence ”, “human ”, and “cheesecake ”. We propose induction algorithms encoding a diverse set of linguistic insights (semantic prosody, distributional similarity, semantic parallelism of coordination) and prior knowledge drawn from lexical resources, resulting in the first broad-coverage connotation lexicon.

socksocket([family[, type[, proto]]]) -> socket object
Open a SOCKS enabled socket. The parameters are the same as
those of the standard socket init. In order for SOCKS to work,
you must specify family=AF_INET, type=SOCK_STREAM and proto=0. |
| |
- Method resolution order:
- socksocket
- socket._socketobject
- __builtin__.object
Methods defined here:
- __init__(self, family=2, type=1, proto=0, _sock=None)
- connect(self, destpair)
- connect(self, despair)
Connects to the specified destination through a proxy.
destpar - A tuple of the IP/DNS address and the port number.
(identical to socket's connect).
To select the proxy server use setproxy().
- getpeername(self)
- getpeername() -> address info
Returns the IP address and port number of the destination
machine (note: getproxypeername returns the proxy)
- getproxypeername(self)
- getproxypeername() -> address info
Returns the IP and port number of the proxy.
- getproxysockname(self)
- getsockname() -> address info
Returns the bound IP address and port number at the proxy.
- setproxy(self, proxytype=None, addr=None, port=None, rdns=True, username=None, password=None)
- setproxy(proxytype, addr[, port[, rdns[, username[, password]]]])
Sets the proxy to be used.
proxytype - The type of the proxy to be used. Three types
are supported: PROXY_TYPE_SOCKS4 (including socks4a),
PROXY_TYPE_SOCKS5 and PROXY_TYPE_HTTP
addr - The address of the server (IP or DNS).
port - The port of the server. Defaults to 1080 for SOCKS
servers and 8080 for HTTP proxy servers.
rdns - Should DNS queries be preformed on the remote side
(rather than the local side). The default is True.
Note: This has no effect with SOCKS4 servers.
username - Username to authenticate with to the server.
The default is no authentication.
password - Password to authenticate with to the server.
Only relevant when username is also provided.
Data descriptors defined here:
- __dict__
- dictionary for instance variables (if defined)
Methods inherited from socket._socketobject:
- accept(self)
- accept() -> (socket object, address info)
Wait for an incoming connection. Return a new socket representing the
connection, and the address of the client. For IP sockets, the address
info is a pair (hostaddr, port).
- bind(self, *args)
- bind(address)
Bind the socket to a local address. For IP sockets, the address is a
pair (host, port); the host must refer to the local host. For raw packet
sockets the address is a tuple (ifname, proto [,pkttype [,hatype]])
- close(self)
- close()
Close the socket. It cannot be used after this call.
- connect_ex(self, *args)
- connect_ex(address) -> errno
This is like connect(address), but returns an error code (the errno value)
instead of raising an exception when an error occurs.
- dup(self)
- dup() -> socket object
Return a new socket object connected to the same system resource.
- fileno(self, *args)
- fileno() -> integer
Return the integer file descriptor of the socket.

Return the address of the local endpoint. For IP sockets, the address
info is a pair (hostaddr, port).
- getsockopt(self, *args)
- getsockopt(level, option[, buffersize]) -> value
Get a socket option. See the Unix manual for level and option.
If a nonzero buffersize argument is given, the return value is a
string of that length; otherwise it is an integer.
- gettimeout(self, *args)
- gettimeout() -> timeout
Returns the timeout in floating seconds associated with socket
operations. A timeout of None indicates that timeouts on socket
operations are disabled.
- listen(self, *args)
- listen(backlog)
Enable a server to accept connections. The backlog argument must be at
least 1; it specifies the number of unaccepted connection that the system
will allow before refusing new connections.
- makefile(self, mode='r', bufsize=-1)
- makefile([mode[, bufsize]]) -> file object
Return a regular file object corresponding to the socket. The mode
and bufsize arguments are as for the built-in open() function.
- sendall(self, *args)
- sendall(data[, flags])
Send a data string to the socket. For the optional flags
argument, see the Unix manual. This calls send() repeatedly
until all data is sent. If an error occurs, it's impossible
to tell how much data has been sent.
- setblocking(self, *args)
- setblocking(flag)
Set the socket to blocking (flag is true) or non-blocking (false).
setblocking(True) is equivalent to settimeout(None);
setblocking(False) is equivalent to settimeout(0.0).
- setsockopt(self, *args)
- setsockopt(level, option, value)
Set a socket option. See the Unix manual for level and option.
The value argument can either be an integer or a string.
- settimeout(self, *args)
- settimeout(timeout)
Set a timeout on socket operations. 'timeout' can be a float,
giving in seconds, or None. Setting a timeout of None disables
the timeout feature and is equivalent to setblocking(1).
Setting a timeout of zero is the same as setblocking(0).
- shutdown(self, *args)
- shutdown(flag)
Shut down the reading side of the socket (flag == SHUT_RD), the writing side
of the socket (flag == SHUT_WR), or both ends (flag == SHUT_RDWR).

Lufthansa scraps 1,300 flights over two-day German strike
FRANKFURT AM MAIN: Lufthansa said Wednesday (Nov 6) it was scrapping 1,300 flights as German cabin crew pressed ahead with a two-day strike, plunging passengers into travel chaos amid an escalating row over pay and conditions.
"As a result of the strike, around 180,000 passengers will be affected by 1,300 flight cancellations," the airline said in a statement after losing a last-minute court battle to halt the walkout.
The 48-hour stoppage called by the UFO flight attendants' union is due to start at 2300 GMT on Wednesday and last until 2300 GMT on Friday.
The union said the stoppage would affect all Lufthansa departures in Germany during that time.
Germany's largest airline said it "regrets the inconvenience for the passengers".
The carrier was putting together an alternative flight schedule where possible, it said, adding that affected passengers could rebook their journeys for free or swap their domestic flights for train tickets.
The announcement of 700 flight cancellations on Thursday and roughly 600 on Friday comes after a Frankfurt labour court denied Lufthansa's request for an injunction to block the strike.
The court ruled that the strike was legal.
Hoping to still avert the upheaval, Lufthansa CEO Carsten Spohr has invited UFO and two rival unions for last-ditch talks on Wednesday evening.
The UFO union has said the strike was necessary because negotiations with Lufthansa bosses were deadlocked.
The union already staged a day-long warning strike last month at four Lufthansa subsidiary airlines, causing several dozen flight cancellations at Eurowings, Germanwings, SunExpress and Lufthansa CityLine.
But the Lufthansa brand was spared after management offered a surprise two-percent pay rise to avoid flight disruptions at its flagship unit.
Since then however, UFO said no progress had been made in talks.
In addition to higher pay for cabin crew across the Lufthansa group, UFO is demanding more benefits and easier routes into long-term contracts for temporary workers.
Lufthansa bosses meanwhile believe that UFO does not have the right to represent workers after an internal leadership tussle, and have challenged the union's legal status in court.
Months of infighting have cost the union members and support among cabin crew, some of whom have now turned to other representative organisations.

Money can be combined with others quantities, e.g hourly rate ($/h), weight price ($/Kg), dimensional checks is performed like for any other quantity. You may also perform conversion on these quantities, e.g. $/gal to €/L. Conversions between quantities stated in different currencies is possible if the exchange rate for the currencies has been set. This is an unidirectional setting. Setting the conversion from USD to EUR does not set the conversion rate from EUR to USD.
Using the physics module, money amounts or combination of money amount and others physical quantities can be operated upon
as illustrated here:[code]
import javax.measure.quantity.Length;
import javax.measure.unit.Unit;
import org.jscience.economics.money.Money;
import org.jscience.economics.money.MoneyAmount;
import org.jscience.mathematics.number.Float64;
import org.jscience.physics.amount.Amount;
import static javax.measure.unit.SI.*;
import static javax.measure.unit.SI.MetricPrefix.*;
import static javax.measure.unit.NonSI.*;
import static org.jscience.economics.money.Currency.*;
public class Main {
public static void main(String[] args) {
// Use currency symbols instead of ISO-4217 codes (only for locale format, see Measure.toStringLocale())
USD.setLabel("$"); // Use "$" symbol instead of currency code ("USD")
EUR.setLabel("€"); // Use "€" symbol instead of currency code ("EUR")
// Combination of money and physical quantities.
Amount
The exchange rates between {@link org.jscience.economics.money.Currency currencies} is {@link javolution.context.LocalContext context local}. Applications may use different sets of exchange rates concurrently. Furthermore, rates for buying and rates for selling may be different. For example:[code] LocalContext.enter(); try { EUR.setExchangeRate(1.4505, USD); // EUR to USD (local rate) MoneyAmount price = MoneyAmount.valueOf(9, 99, EUR); System.out.println("Price: " + price.to(USD); } finally { LocalContext.exit(); } ... LocalContext.enter(); try { USD.setExchangeRate(0.6643, EUR); // USD to EUR (local rate) MoneyAmount price = MoneyAmount.valueOf(14, 99, USD); System.out.println("Price: " + price.to(EUR); } finally { LocalContext.exit(); }[/code]
Like any {@link org.jscience.physics.amount.Amount amount},
money quantities can be used with any number type.
[code]
// Calculates trip cost using Decimal numbers.
Amount


How I got blocked on a simple problem. I had to write some code that would take a list of numbers and remove all odd numbers. I was using this code that was prewritten by people behind mozilla and it all seemed to be working until I noticed that 0 doesn't show up. As 0 is also even this was an issue. And although I suspected where the issue might be I was reluctant to test that path first as I would second guess some simpler code first. Ofcourse once I persuaded my initial doubts I quickly came to realise that this pre written code that I'm using doesn't consider 0 a worthy number of leaving it in my list. This was solved by changing 1 word...
How I solved a problem in an elegant way. This happened when I entered the final phase of this weeks javascript challenges. Suddenly in the code examples in front of me there is a new way of defining a function and man oh man how this confused me. First thing I had in my mind was to just rewrite it in the usual way I'm used to see them but I managed to stand firm against this temptation and started researching how this way of writing them works. Resources were a bit hard to understand at first but once I felt like I understand how to write them I actually succeeded with first attempt. Afterwards I even nested these functions which made me feel extra cool.


plcmdio32(1) Qualcomm Atheros Open Powerline Toolkit plcmdio32(1) NAME plcmdio32 - Qualcomm Atheros 32-bit MDIO Register Editor SYNOPSIS plcmdio32 [options] [device] [device] [...] DESCRIPTION Read or write global MDIO registers using multiple VS_MDIO_COMMAND vendor-specific management messages. Commands are entered using 32-bit register and data values then converted to threeequivalen 16-bit commands. The default operation is to read a register. Registers are written only if data is specified on the command line. Thsi program replaces pro‐ gram int6kmdio2. This program writes MDIO instructions using 802.3ae Clause 45 (address, data and mask) format. See program int6kmdio for a similar program to write instructions using 802.3 Clause 22 (phy, reg, data and mask) format. This program is part of the Qualcomm Atheros Powerline Toolkit. It replaces legacy program int6kmdio2. See the plc man page for an overview and installation instructions. OPTIONS -a address The 19-bit global register address. Some devices may not support all possible addresses. Addresses may be expressed in decimal, hexadecimal or binary notation. Hexadecimal values must be prefixed with "0x" or "0X". Binary values must be prefixed with "0b" or "0B". -d data A 32-bit data value to be inserted into the specified register. The specified data value is written when this option is present; otherwise the specified register is read and the content is displayed. Data values may be expressed in decimal, hexadecimal or binary notation. Hexadecimal values are prefixed with "0x" or "0X". Binary values are prefixed with "0b" or "0B". -e Redirects stderr messages to stdout. By convention status and error messages are printed on stderr while primary program output is printed on stdout. This option prints all output on stdout in cases where this is desired. -h When writing 32-bit values, write to the high-order register before the low-order register. This option is needed in cases where the value in one register may affect the interpretation of some value written to the other regis‐ ter. This is not a common situation. -i interface Select the host Ethernet interface. All requests are sent via this host interface and only reponses received via this host interface are recognized. The default interface is eth1 because most people use eth0 as their principle network connection; however, if environment string "PLC" is defined then it takes precedence over the default interface. This option then takes precedence over either default. -q Suppresses status messages on stderr. -v Prints additional information on stdout. In particular, this option dumps outgoing Ethernet packets on stdout. -?,--help Displays program help information on stderr. This option takes precedence over all other options on the command line except version information. -!,--version Displays program version information on stderr. This option takes precedence over all other options on the com‐ mand line except help information. Use this option when sending screen dumps to Atheros technical staff. ARGUMENTS device The MAC address of some powerline device. More than one address may be specified. If more than one address is specified then operations are performed on each device in turn. The default address is local. See DEVICES for information about symbolic device addresses. DEVICES Powerline devices use Ethernet Media Access Control (MAC) addresses. A MAC address is a 48-bit value entered as 12 hex‐ adecimal digits in upper, lower or mixed character case. Octets may be separated with colons for clarity. For example, "00b052000001", "00:b0:52:00:00:01" and "00b052:000001" are valid and equivalent. The following MAC addresses are special and may be entered by name instead of number. all Same as "broadcast". broadcast A synonym for the Ethernet broadcast address, FF:FF:FF:FF:FF:FF. All devices, whether local, remote or foreign recognize messages sent to this address. A remote device is any device at the far end of a powerline connection. A foreign device is any device not manufactured by Atheros. local A synonym for the Qualcomm Atheros vendor specific Local Management Address (LMA), 00:B0:52:00:00:01. All local Atheros devices recognize this address but remote and foreign devices do not. A remote device is any device at the far end of a powerline connection. A foreign device is any device not manufactured by Atheros. REFERENCES See the Qualcomm Atheros HomePlug AV Firmware Technical Reference Manual for technical information.

--- name: angular url: /angular title: Angular ---
Gulp will watch for file changes in the client
directory. Upon change, all files will be copied over to the build
directory and the webserver will be reloaded. Note that the build directory will be deleted and recompiled upon each change. This means that any updates to files in the build
directory will be deleted.
To simplify the routing process, this project includes dynamic routing. Here's how it works:
client/templates
)name
which you'd want to use with ui-sref
(the ui-router way of linking pages) and a url
which that template can be accessible throughgulp
to compile the project into the build
folderThis app depends on the use of front matter
which is text prepended to templates like so:
Front matter follows YAML conventions. For dynamic routing, a name
and url
have to be used (as discussed above). There are some other options.
Your routes will be called into a view, which is essentially a hole in your page for the content to go in. A route looks like the following:
parent
to specify a parent template. This can also be done using standard dot-delimited convention in the name. So you can either do this:
or this:
Note that this specifies child
templates. This means that when mail
loads up, it'll have to have a element into which a child is loaded. A child will need a
url
as well but note that the URL will be appended to the parent's URL like so:
will be accessible via /mail
while the child:
will be accessible via /mail/inbox
. This specific URL has to be typed in in order for the child to show up. This allows us to specify several children (inbox
, sent
, trash
, etc.).
Angular supports this neat thing called controllers. They can get confusing and so each template gets its own DefaultController
which can be overridden like so:
Among other things, the default controller passes a bunch of data through. For instance, all of your front-matter settings will be accessible via vars
in your template. {{ vars.name }}
will return the name of your route while {{ vars.path }}
will return the relative path to the template.
If you use dynamic parameters in your URL, those parameters will be accessible via params
so if your URL is:
It will match any URL that follows that pattern (so /mail/inbox/383828
would match as well as /mail/inbox/my-email
but not /mail/inbox/3838/something
).
Note that override a controller disables front-matter settings (except Dynamic Routing). If you want to use your own controller AND keep this feature, you can extend the DefaultController
:
Angular and the UI router support animations. That means that when you transition from a page to another page, you can CSS animate it. It's easy to do with CSS; however, you can use front matter to register CSS animations:
The animation data gets registered for the template (only if it's a child or parent, not a partial) and will fire in the appropriate times.
Please note that the default AngularJS behavior for animations is to trigger both the "in" animation of a new element and the "out" animation of an element (ng-enter
and ng-leave
respectively) at the same time which will cause both views to appear together.
The ability to sync
transitions together has been delayed from v1.2 to 1.3 and finally as a possibility for 2.0 ref
Note: Please don't forget to add the ui-animation
attribute wherever you have ui-view
in order to hook your animations up to that event!
Sometimes, it's more beneficial to use composed views rather than simple one-off views. For instance, having a dedicated file for a navigation, or a sidebar is much more useful separate than embedded. For these purposes, there's Angular's ng-include
:
The partial will be automatically pulled in and placed in the correct place.
To enable HTML5 mode with Angular (using regular URLs unprefixed by "\#"), a server has to support URL rewrites. The UI Router docs have a great write up on working with the HTML5mode and how to enable it on a variety of servers.
Foundation for Apps supports this out of the box for the development environment; however, for production, additional steps will be necessary.
If you'd like to run Foundation for Apps without HTML5 mode there is a line of code in the app.js
that can be commented out:
Note that Foundation for Apps cannot be run directly through the browser because it uses XMLHttpRequests to load up templates/partials for directives and pages. Running it directly will cause cross origin issues and will not work with linking.
If you are running in a subdirectory, try setting requireBase
to the subdirectory name. So if you're running domain.com/subdirectory
, set requireBase: '/subdirectory/'
.
All of the directives are supported as attribute directive so you can add them to an element like so:
However, some directives allow element-level declaration like so:
Note that some directives will REPLACE your original element, in others the directive will become a child of the original element.
Wherever necessary, IDs will also be included to show that IDs are required in order for the directives to work correctly.
There are some nuances of Angular itself and some of the libraries Foundation for Apps includes and uses that can make prototyping easier and quicker. Here's a rundown of some of these tools:
ui-srefInstead of using <a href="/my/sub/page">
in a page to access another page, it's common practice to use the router. Foundation for Apps uses UI Router for its routing which allows for named route references. For instance, let's say there is a page with this front matter:
You can easily link to it like so:
ui-sref
can also take in parameters for pages that accept parameters. Here's another example page that uses parameters:
The page can be accessed via 5th messages
.
ui-sref-active
Now let's say we want to create a menu of links and want to make sure that the active link gets an extra special class to indicate that it is, indeed, active. There are two very similar ways to do this. The first one is using ui-sref-active
, you can place this directive on either the ui-sref
element or on its parent. When active, it will add a class of your choosing:
The other way is using ui-sref-active-eq
which works almost the same with one difference. Whenever accessing a child page, the parent page will show up as active whenever using ui-sref-active
. The ui-sref-active-eq
is triggered ONLY when a specific page is triggered, no matter what their parent is.
In the previous example with inbox and inbox.message, the inbox page would show up as active with ui-sref-active
when on the inbox.message page. With ui-sref-active-eq
, inbox would show up as active only when specifically on the inbox page.
If none of this makes sense, stick with ui-sref-active-eq
Foundation has some great helpers that foster better interaction between elements.
zf-closezf-close
looks for a parent element that has the zf-closable
tag on it. This tag is added automatically for all directives that can be closed with zf-close
. When clicked, the directive will send a message via the FoundationApi to close its parent zf-closable
element.
Note that you can specify the ID of a specific closable directive in order to close it remotely (whether it's a parent, child, or has any other relationship to the closable directive).
The counter to zf-close
, zf-open
sends a signal to a directive that can be trigger through this method. Simply specify the ID of the target element.
Similar to the previous two, zf-toggle
sends a toggle command to a directive that can accept it. A target has to be specified in order for it to work.
zf-hard-toggle
behaves exactly like toggle, but upon opening the target, it will close any other element that is currently open (essentially clearing the board). These might include modals, notifications, panels, off-canvas menus, etc.
Please see documentation on the FoundationApi to learn how to open, close, toggle, and trigger other events programmatically.
At the heart, most of the Foundation components use an Angular service called FoundationApi. The code itself is very simple but has some powerful applications.
The most used feature is its subscribe/publish system. Every single directive that can be "closed" subscribes itself to the subscribe/publish system under its ID and will perform specific tasks whenever someone publishes a message under that ID.
Here's an example:
The modal will automatically register itself as a subscriber in the FoundationApi under my-modal
. The code for the directive indicates that it listens for 3 different messages: open
, close
, and toggle
as well as aliases for the former two show
and hide
.
Sometimes, it's necessary to trigger a modal after some piece logic was satisfied. Whether the user scrolled past a certain point or some other action happened. Here's how to open our modal remotely:
Make sure to include FoundationApi as a dependency in the controller or wherever else you want to use it. The best bet to hooking into various directives is to check the code and see what each directive subscribes to.
In fact, the directives zf-close
, zf-open
, and zf-toggle
are wrappers for FoundationApi events.
Most of the modules are dependent on the foundation.common.services
module but outside of that, they're portable. You're welcome to take them and use them as you need to; however, there are some things to know about:
zf-open
and zf-close
are packaged in the foundation.common.directives
module so if there is a need for them, require the module.app.js
file which bootstraps the application can be fully bypassed so you can build your own. Make sure to use proper dependency injection for the modules you DO want to use.As of v1.1, Foundation for Apps will/does support being included via dependency injection. If you're building your own application or want to include FA in an existing application, here's what you need to know:
foundation.core
which includes the FoundationApi
service as well as several different factories/services that help it chug along. Most notably, it includes a configuration that imports SASS media queries. This is necessary for Interchange.foundation
module imports all of the directives, common directives, and foundation.core
.foundation.dynamicRouting
is a module that sets up the ui.router
routing.foundation.dynamicRouting.animations
is an additional module for foundation.dynamicRouting
which enables view animationWhen creating a custom app.js
, the only necessary configuration is setting up the $urlProvider
and $locationProvider
. The sample configuration is included in the app.js
in the js/angular
folder.


Twitches are common and very rarely a sign of anything serious. They often go away on their own, but see a GP if a twitch lasts more than 2 weeks.
Twitches are usually nothing to worry about
Most people get twitches from time to time.
They're often linked to:
- stress and anxiety
- tiredness and exhaustion
- drinking caffeine or alcohol
- some medicines – check the side effects on the packet or leaflet
Twitches can affect any part of the body. Twitches in the eyes or legs are particularly common.
You may also have tingling or cramps (spasms) in the same area.
How you can help stop a twitch
A twitch may come and go, but will normally stop in a few days or weeks.
There’s not usually any treatment for it.
But there are some things you can do to help.
Do
-
get plenty of rest
-
try to find ways to relax
-
stretch and massage any muscles affected by cramps
-
try not to worry about it – a twitch is usually harmless and worrying can make it worse
Don’t
-
do not drink lots of caffeine, such as tea and coffee
-
do not drink lots of alcohol
-
do not stop taking a prescribed medicine without getting medical advice, even if you think it could be causing your twitch
Non-urgent advice: See a GP if:
- you have a twitch for more than 2 weeks
- you have a twitch in more than 1 place
- the affected area feels weak or stiff
- you think a prescribed medicine might be causing your twitch
Coronavirus (COVID-19) update: how to contact a GP
It's still important to get help from a GP if you need it. To contact your GP surgery:
- visit their website
- use the NHS App
- call them
What happens at your GP appointment
If your twitch does not go away, your GP may:
- check for causes like stress or a medicine you're taking
- ask you to come back if the twitch has not stopped in a few weeks
- refer you to a specialist called a neurologist for tests to look for conditions that can cause a twitch
Conditions that can cause a twitch
Most twitches are not caused by a medical condition.
Some possible causes of a twitch that does not go away or happens with other symptoms include:
- benign fasciculation syndrome (long-lasting twitches and cramps caused by overactive nerves)
- dystonia (a group of uncommon conditions that cause muscle spasms)
- motor neurone disease (an uncommon condition that causes weakness and gets worse over time)

Perl Weekly
Issue #204 - 2015-06-22 - Randal Schwartz is getting old
latest | archive | by Neil Bowers
|
|
Some weeks there are clear themes in the Perl-related blog posts,
such as just after a YAPC or major release. And then other weeks
are all over the place. That's a good thing, I think.
WebAssembly is probably of interest to many readers, as a possible
new compilation format for the web.
But my favourite entry this week is about Daniel Stenberg's
dedication to the cURL project: 17 years and still going strong!
 A Perl 6 hackathon will run throughout, keynotes and talks are on the Friday, and Larry Wall will be there.
|

|
|
Not Perl
|
WebAssembly
Microsoft, Apple, Google, and Mozilla have started working on a compiled code format for web browsers. Where languages currently compile down to Javascript, in the future they could compile down to WebAssembly. See also this post by Abel Avram

17 Years of curl With Daniel Stenberg
Not Perl, and not even in the last week, but I came across this today. What struck me is the line that Daniel "has spent at least 2 hours every day for the past 17 years working on and maintaining curl (~13k hours)". Read more about Daniel and cURL on his blog. Now that is dedication to an open-source project!

US clears sale of USD 1 billion worth of naval weapons to India
India will use the enhanced capability as a deterrent to regional threats and to strengthen its homeland defence, it said.
by PTIWashington: The Trump Administration has notified to the United States Congress its determination to sell naval guns for use against warships, anti-aircraft and shore bombardment worth a billion dollars to India, in a move that would enhance the capabilities of the Indian Navy.
The proposed foreign military sale of up to 13 MK-45 5-inch/62 caliber (MOD 4) naval guns and related equipment is at an estimated cost of 1.0210 billion dollars, Defence Security Cooperation Agency said in its notification to the Congress on Tuesday.
To be manufactured by the BAE Systems Land and Armaments, the proposed sale will improve India's capability to tackle current and future threats from enemy weapon systems, the notification said.
"The MK-45 Gun System will provide the capability to conduct anti-surface warfare and anti-air defence missions while enhancing interoperability with the US and other allied forces," the notification said.
India will use the enhanced capability as a deterrent to regional threats and to strengthen its homeland defence, it said.
The proposed sale of this equipment and support will not alter the basic military balance in the region, it said.
According to the notification, this notice of a potential sale is required by law and does not mean the sale has been concluded.
With this, India has become one of the few countries that the US decided to sell its latest version (Mod 4) of naval guns. The other countries are Australia, Japan and South Korea.
The one given to Thailand is an upgraded MOD 4 version. The US has also determined to sell these to a few other allies including Britain and Canada.

Hello. Today I will try to make an extension to the Knuth's Arrow Notations. Arrow Notations is defined as following:
Now, I interpreted the multiple \(\uparrow\)s as multiplication, so first I thought of multiplication by a number. By the generic rule of hyper operations, I thought of the following:
\(a\left(\uparrow^nm\right)b=a\uparrow^{n}a\uparrow^{n}a...\uparrow^{n}b\) (m copies of a)
Which makes little more sense if it was interpreted like that:
\(a\left(\uparrow^nm\right)b=f^m(b)\) where \(f(x)=a\uparrow^nx\)
So, the generic rule can be rewritten like this:
\(a\uparrow^n b=a\left(\uparrow^{n-1}(b-1)\right)a=a\left(\uparrow^{n-1}b\right)1\)
And function \(f(n)=n(\uparrow^nn)n=n\uparrow^{n+1}(n+1)\) have growth rate somewhat comparable to \(f_\omega(n+1)\) in fast growing hierarchy.
Then, as I do this, I thought of making more complex expression can be done with this.
I saw that the multiplicated arrow rule goes following:
\(a\left(\uparrow^nm\right)b=a\left(\underset{m}{\underbrace{\uparrow^n+\uparrow^n+...+\uparrow^n}}\right)b=\underset{m}{\underbrace{a\uparrow^na\uparrow^n...\uparrow^n}}b\)
So, I thought I could have each added uparrows to have different number of arrows. This lead to the following:
\(a\left(\uparrow^{n_1}+\uparrow^{n_2}+...+\uparrow^{n_k}\right)b=a\uparrow^{n_1}a\uparrow^{n_2}...\uparrow^{n_k}b\)
This notations are not communitive, so it should not be calculated inside the arrows.
Here, I defined the arrow multiplication with paranthesis.
\(a\left(\uparrow^{n_{1,1}}+\uparrow^{n_{1,2}}+...+\uparrow^{n_{1,k}}\right)\left(\uparrow^{n_{2,1}}+\uparrow^{n_{2,2}}+...+\uparrow^{n_{2,l}}\right)b\)
\(=f^{\left(\uparrow^{n_{2,1}}+...+\uparrow^{n_{2,l}}\right)}(b)\;\text{where}\;f(x)=a\left(\uparrow^{n_{1,1}}+...+\uparrow^{n_{1,k}}\right)x=a\uparrow^{n_{1,1}}...\uparrow^{n_{1,k}}x\)
\(=\underset{a\left(\uparrow^{n_{2,1}}+...+\uparrow^{n_{2,l}}\right)b}{\underbrace{a\left(\uparrow^{n_{1,1}}+...+\uparrow^{n_{1,k}}\right)...\left(\uparrow^{n_{1,1}}+...+\uparrow^{n_{1,k}}\right)b}}\)
So multiple multiplications can be calculated right to left:
\(a(@_1@_2...@_k)b\)
\(=\underset{\underset{\underset{a@_kb}{\underbrace{\vdots}}}{\underbrace{a@_2...@_2b}}}{\underbrace{a@_1...@_1b}}\;\text{where}\;@_n\;\text{is an operation represented by arrows}\)
Addition of paranthesis can be just connected.
\(a\left(\left(\uparrow^{n_{1,1}}+\uparrow^{n_{1,2}}+...+\uparrow^{n_{1,k}}\right)+\left(\uparrow^{n_{2,1}}+\uparrow^{n_{2,2}}+...+\uparrow^{n_{2,l}}\right)\right)b\)
\(=a\left(\uparrow^{n_{1,1}}+...+\uparrow^{n_{1,k}}\right)\left(a\left(\uparrow^{n_{2,1}}+...+\uparrow^{n_{2,l}}\right)b\right) \)
\(=a\left(\uparrow^{n_{1,1}}+...+\uparrow^{n_{1,k}}+\uparrow^{n_{2,1}}+...+\uparrow^{n_{2,l}}\right)b\)
I define the following two numbers:
Centicave=\(100\left(\uparrow^{100}1+\uparrow^{99}2+...+\uparrow^{1}100\right)100\)
Centivex=\(100\left(\uparrow^{1}100+\uparrow^{2}99+...+\uparrow^{100}1\right)100\)
So then I thought of adding instead the higher operations into the arrows.
First is to put arrows onto the exponents, obviously.
Looking at the multiplication by a number turns into by arrows, it makes so that it is equivalent to multiplying to the second operant, as seen above, so the exponentiated arrows would make the number of arrows turn into something related to the operand. This lead me to do the following:
\(a\left(\uparrow^{\uparrow^n}\right)b\)
\(=\underset{a\uparrow^nb}{\underbrace{a\uparrow\uparrow...\uparrow b}}\)
\(=a\uparrow^{a\uparrow^nb}b\)
And iterated exponents? Easy.
\(a\left(\uparrow^{\uparrow^{\cdots^n}}\right)b\)
\(=a\uparrow^{a\uparrow^{\cdots^{a\uparrow^nb}}b}b\)
And operations exponentiated applies to the each applied operation. Examples:
\(a\left(\uparrow^{\uparrow^4}3\right)b\)
\(=a\uparrow^{a\uparrow^4b}a\uparrow^{a\uparrow^4b}a\uparrow^{a\uparrow^4b}b\)
\(a\left(\uparrow^{\uparrow^{\uparrow^3}2}+\uparrow^{\uparrow^2}3\right)b\)
\(=a\uparrow^{a\uparrow^{a\uparrow^3b}a\uparrow^{a\uparrow^3b}b}a\uparrow^{a\uparrow^2b}a\uparrow^{a\uparrow^2b}a\uparrow^{a\uparrow^2b}b\)
Wow, it gets pretty complicated. I probably not going to expand too much then.
Well, the function \(f(n)=n(\uparrow^{\uparrow^n})n\) have growth rate of around \(f_\omega(f_\omega(n))=f_\omega^2(n)\).
Ok, now I did exponentiation, how about tetration level? Same idea. Just hope not to mess up. I will use \(\{\}\) around the arrow operations to arrows to not confuse it between.
\(a(\uparrow^m\{\uparrow\uparrow\}n)b\)
\(=a\left(\left.(\uparrow^m)^{(\uparrow^m)^{\cdots}}\right\}n\right)b\)...?
Wait wait wait that's not going to work. Arrows don't work like numbers. I can't just replace it with \(x\) or something. I have to think it differently. How about this?
\(a(\uparrow^m\{\uparrow\uparrow\}n)b\)
\(=a\left(\left.\uparrow^{\uparrow^{\cdots^m}}\right\}n\right)b\)
\(=\left.\underset{\underset{\underset{a\uparrow^mb}{\underbrace{\vdots}}}{\underbrace{a\uparrow\uparrow...\uparrow b}}}{\underbrace{a\uparrow\uparrow...\uparrow b}}\right\}n\) (the count \(n\) is not including \(m\) or \(a\uparrow^mb\))
Therefore, the growth rate of \(f(n)=n(\uparrow^n\{\uparrow\uparrow\}n)n\) is \(f_\omega^n(n)=f_{\omega+1}(n)\).
So yeah this is more logical. Also, in this notation the Graham's number \(g_{64}\) is way easier to represent.
\(g_{64}=3(\uparrow^4\{\uparrow\uparrow\}63)3\)
Or, the \(g_n\) sequence can be represented very simply:
\(g_n=3(\uparrow^4\{\uparrow\uparrow\}(n-1))3\)
And yes, with some thinking, the notation will represent the sequence in the exactly same form.
I define these numbers:
Sheetquart=\(4(\uparrow\{\uparrow\uparrow\}2)4\)
Stackquart=\(4(\uparrow\{\uparrow\uparrow\}16)4\)
Towerquart=\(4(\uparrow\{\uparrow\uparrow\}2^{20})4\)
Tetragol=\(100(\uparrow^{100}\{\uparrow\uparrow\}100)100\)
I love powers of 2.
Let's define it recursively to make later jobs easier:
\(a(\uparrow^n\{\uparrow\uparrow\}m)b=\left\{\begin{matrix}a\uparrow^nb&m=0\\a\left(\uparrow^{\uparrow^n\{\uparrow\uparrow\}(m-1)}\right)b&else\end{matrix}\right.\)
Now I can define tetration tower! Well, it works just like regular tetrations, but to not to make it broken, I had to take some liberty again. It is still calculated from right to left, but it is extended differently.
\(a(@\{\uparrow\uparrow\}\alpha)b=\left\{\begin{matrix}a@b&\alpha=0\\a\left(\uparrow^{@\{\uparrow\uparrow\}(\alpha-1)}\right)b&\alpha\in\mathbb{N}\\a\left(@\{\uparrow\uparrow\}(a\alpha b)\right)b&else\end{matrix}\right.\) where \(@\) is the left most operation of iterated tetrations and \(\alpha\) can be a number or arrow structure
Remember that the order of operations are paranthesis, tetration+ hyperoperations, exponentiation, multiplication, and then addition.
Now I made it recursive, it is easier to define it into any hyperoperations.
\(a(@\{\uparrow^n\}\alpha)b=\left\{\begin{matrix}a@b&\alpha=0\\a\left(@\{\uparrow^{m-1}\}(@\{\uparrow^m\}(\alpha-1))\right)b&\alpha\in\mathbb{N}\\a\left(@\{\uparrow^n\}(a\alpha b)\right)b&else\end{matrix}\right.\) where \(@\) is the left most operation of iterated hyperoperations and \(\alpha\) can be a number or arrow structure
And, since \(a(@\{\uparrow^n\}\alpha)b=a(@\{\uparrow^{n-1}\}@\{\uparrow^{n-1}\}...\alpha)b\), the growth rate of functions \(f(n)=n(n\{\uparrow^a\}n)n\) where a is constant and \(g(n)=n(n\{\uparrow^n\}n)n\) have growth rate of \(f_{\omega+(a-1)}(n)\) and \(f_{\omega2}(n)\) respectively.
Now I define more numbers.
Pentagol=\(100\left(\uparrow^{100}\{\uparrow^{100}\}100\right)100\)
Centicaver=\(100\left(\uparrow^{100}\{\uparrow^1\}\uparrow^{99}\{\uparrow^2\}...\{\uparrow^{100}\}\uparrow^1\right)100\)
Centivexer=\(100\left(\uparrow^1\{\uparrow^{100}\}\uparrow^2\{\uparrow^{99}\}...\{\uparrow^1\}\uparrow^{100}\right)100\)
Now that is done, let's have something else than just arrows inside \(\{\}\)!
How I do that? Well, there can be addition and multiplication inside just like before and let them act like before! It is just that a and b is replaced with bunch of other arrows. It is hard to explain with a definition, so I will just put examples:
\(a(\uparrow^3\{\uparrow^3+\uparrow^22\}\uparrow^4)b\)
\(=a(\uparrow^3\{\uparrow^3\}\uparrow^3\{\uparrow^2\}\uparrow^3\{\uparrow^2\}\uparrow^4)b\)
To compute stacked arrows, to hold the equality of plus sign, the expression is opened first.
\(a(\uparrow^2+\uparrow^3\{\uparrow^{\uparrow^4}\}\uparrow^2+\uparrow^5)b\)
\(=a\uparrow^2a(\uparrow^3\{\uparrow^{\uparrow^4}\}\uparrow^2)a\uparrow^5b\)
Since hyperoperations from tetration are always calculated from right to left, it will be paranthesized as following:
\(=a\uparrow^2\left(a(\uparrow^3\{\uparrow^{\uparrow^4}\}\uparrow^2)(a\uparrow^5b)\right)\)
Then, it will take left and right arguments of the whole operation, copy it and put it on the sides the exponent of insidemost arrow, and for left, the arguments are computed with left operation, and for right argument are computed by the right operation. The exponent of arrow will be inside curly brackets and be surrounded by operands of \(\{\}\). Thus, the expression will be
\(=a\uparrow^2\left(\color{magenta}{a}(\color{red}{\uparrow^3}\{\uparrow^{(\color{magenta}{a}\color{red}{\uparrow^3}\color{blue}{(a\uparrow^5b)})(\color{red}{\uparrow^3}\{\uparrow^4\}\color{green}{\uparrow^2})(\color{magenta}{a}\color{green}{\uparrow^2}\color{blue}{(a\uparrow^5b)})}\}\color{green}{\uparrow^2})\color{blue}{(a\uparrow^5b)}\right)\)
Getting rid of some paranthesis will make this:
\(=a\uparrow^2\color{magenta}{a}(\color{red}{\uparrow^3}\{\uparrow^{(\color{magenta}{a}\color{red}{\uparrow^3}\color{blue}{a\uparrow^5b})(\color{red}{\uparrow^3}\{\uparrow^4\}\color{green}{\uparrow^2})(\color{magenta}{a}\color{green}{\uparrow^2}\color{blue}{a\uparrow^5b})}\}\color{green}{\uparrow^2})\color{blue}{a\uparrow^5b}\)
So, the exponentiated arrows inside of \(\{\}\)s will be like this:
\(\color{magenta}a(\color{red}{@_a}\{\uparrow^\color{olive}{@_e}\}\color{green}{@_b})\color{blue}b\)
\(=\color{magenta}a(\color{red}{@_a}\{\uparrow^{(\color{magenta}a\color{red}{@_a}\color{blue}b)(\color{red}{@_a}\{\color{olive}{@_e}\}\color{green}{@_b})(\color{magenta}a\color{green}{@_b}\color{blue}b)}\}\color{green}{@_b})\color{blue}b\)
*\(\color{magenta}a\) and \(\color{blue}b\) are integer, and \(\color{red}{@_a}\), \(\color{green}{@_b}\), and \(\color{olive}{@_e}\) are operations.
Because when exponent is arrow if right of \(\{\}\) is a number it is currently undefined, I define it as following:
\(a(@_a\{\uparrow^{@_e}\}n)b\)
\(=a(\underset{n\;@_a\text{s}}{\underbrace{@_a\{\uparrow^{@_e}\}@_a\{\uparrow^{@_e}\}...@_a}})b\)
Let \(\mathbb{A}\) be set of all arrow structures
Therefore, the entire recursive definition of exponentiated arrows inside \(\{\}\) is
\(a(@\{\uparrow^\alpha\}\beta)b=\left\{\begin{matrix}a\left(\uparrow^{@\{\uparrow\uparrow\}(\beta-1)}\right)b&\alpha=2\land\beta\not\in\mathbb{A}\\a\left(@\{\uparrow^{\alpha-1}\}@\{\uparrow^\alpha\}(\beta-1)\right)b&\alpha\in\mathbb{N}\backslash2\land\beta\in\mathbb{N}\\a\left(@\{\uparrow^\alpha\}(a\beta b)\right)b&\alpha\in\mathbb{N}\backslash2\land\beta\in\mathbb{A}\\a\left(@\{\uparrow^{(a@b)(@\{\alpha\}\beta)(a\beta b)}\}\beta\right)b&\alpha\in\mathbb{A}\land\beta\in\mathbb{A}\\a\left(@\{\uparrow^\alpha\}<EMAIL_ADDRESS>Domains:
Because the limit of the expression will be \(a(\uparrow\{\uparrow\{...\) , the next obvious option is to describing number of \(\{\}\) nesting as a number. That's what I did.
\(a(@\underset{n}{\underbrace{\{@\{@...@\{}}\text{#}\}\alpha...\}\alpha\}b=a(@\{\{n_\text{#}\}\}\alpha)b\)
And other definition I will just Ctrl+C Ctrl+V.
\(a(@\{\{{n_1}_{\text{#}_1}+{n_2}_{\text{#}_2}\}\}\alpha)b\)
\(=a(@\{\{{n_1}_{\text{#}_1}\}+\{{n_2}_{\text{#}_2}\}\}\alpha)b\)
\(=a(@\{\{{n_1}_{\text{#}_1}\}\}@\{\{{n_2}_{\text{#}_2}\}\}\alpha)b\)
\(a(@\{\{n_\text{#}m\}\}\alpha)b\)
\(=a(@\{\{\underset{m}{\underbrace{n_\text{#}+n_\text{#}...+n_\text{#}}}\}\}\alpha)b\)
\(a(@\{\{\uparrow_\text{#}\}\}\alpha)b=a(@\{\{a(@\{\text{#}\}\alpha)b_\text{#}\}\}\alpha)b\)
\(a(@\{\{\uparrow^\alpha_\text{#}\}\}\beta)b=\left\{\begin{matrix}a(@\{\{a(@\{\text{#}\}\beta)b_\text{#}\}\}\alpha)b&\alpha=1\\a\left(@\{\{\uparrow^{\alpha-1}_\text{#}\}\}@\{\{\uparrow^\alpha_\text{#}\}\}(\beta-1)\right)b&\alpha\in\mathbb{N}\backslash1\land\beta\not\in\mathbb{A}\\a\left(@\{\{\uparrow^\alpha_\text{#}\}\}(a\beta b)\right)b&\alpha\in\mathbb{N}\backslash1\land\beta\in\mathbb{A}\\a\left(@\{\{\uparrow^{(a@b)(@\{\{\alpha_\text{#}\}\}\beta)(a\beta b)}_\text{#}\}\}\beta\right)b&\alpha\in\mathbb{A}\land\beta\in\mathbb{A}\\a\left(@\{\{\uparrow^\alpha_\text{#}\}\}<EMAIL_ADDRESS>Domains:
So, that being defined, it can be generalized to arbiturarly number of \(\{\}\)s.
\(a(@\underset{m}{\underbrace{\{@\{@...@\{}}@_k\}^n_{@_1,@_2,...,@_{k-1}}\alpha...\}^n_{@_1,@_2,...,@_{k-1}}\alpha\}^n_{@_1,@_2,...,@_{k-1}}b=a(@\{m_{@_1,@_2,...,@_k}\}^{n+1}\alpha)b\)
\(a(@\{{n_1}_{\text{#}_1}+{n_2}_{\text{#}_2}\}^n\alpha)b\)
\(=a(@\{{n_1}_{\text{#}_1}\}^n+\{{n_2}_{\text{#}_2}\}^n\alpha)b\)
\(=a(@\{{n_1}_{\text{#}_1}\}^n@\{{n_2}_{\text{#}_2}\}^n\alpha)b\)
\(a(@\{n_\text{#}m\}^n\alpha)b\)
\(=a(@\{\underset{m}{\underbrace{n_\text{#}+n_\text{#}...+n_\text{#}}}\}^n\alpha)b\)
\(a(@\{\uparrow_{@_1,@_2,...,@_n}^n\alpha)b=a(@\{a(@\{{@_n}_{@_1,@_2,...,@_{n-1}}\}^{n-1}\alpha)b_{@_1,@_2,...,@_{n-1}}\}^n\alpha)b\)
\(a(@\{\uparrow^\alpha_\text{#}\}^n\beta)b=\left\{\begin{matrix}a(@\{a(@\{@_{{n-1}_{@_1,@_2,...,@_{n-2}}}\}^{n-1}\beta)b_\text{#}\}^n\alpha)b&\alpha=1\\a\left(@\{\uparrow^{\alpha-1}_\text{#}\}^n@\{\uparrow^\alpha_\text{#}\}^n(\beta-1)\right)b&\alpha\in\mathbb{N}\backslash1\land\beta\not\in\mathbb{A}\\a\left(@\{\uparrow^\alpha_\text{#}\}^n(a\beta b)\right)b&\alpha\in\mathbb{N}\backslash1\land\beta\in\mathbb{A}\\a\left(@\{\uparrow^{(a@b)(@\{\alpha_\text{#}\}^n\beta)(a\beta b)}_\text{#}\}^n\beta\right)b&\alpha\in\mathbb{A}\land\beta\in\mathbb{A}\\a\left(@\{\uparrow^\alpha_\text{#}\}^n<EMAIL_ADDRESS>Domains:
I then thought of shorthand for writing the subscript/the inner entry for the deeper brackets, and that is to use \(\sim\) for the subscript. If the subscript is only the \(\sim\), replace the \(\sim\) with the inner entry if the nesting is two brackets, else add the inner entry after it. In another words, it accounts for abbreviating sufficient amount of the array with the inner entry of deepest brackets.
Therefore, Tricover can be rewritten little shorter as \(3(\uparrow^3\{\uparrow^3_\sim\}^3\uparrow^3)3\).
The functions \(f(n)=n\left(\uparrow^n\{n_\sim\}^a\uparrow^n\right)n\) where a is a constant and \(g(n)=n\left(\uparrow^n\{n_\sim\}^n\uparrow^n\right)n\) have growth rates \(f_{\omega(a+1)}(n)\) and I think \(f_{\omega^2}(n)\).
Note that \(3(\uparrow\{\uparrow^2+\uparrow\}3)3\) and \(3(\uparrow\{(\uparrow^2+\uparrow)\}3)3\) are different because the first one is interpreted as multiple operations added together and the latter is interpreted as one operation.
Now, I am thinking of the arrays in exponents, but only works with only the \(\sim\) in subscript. If the array is form of \(1,1,...,\alpha,...\), replace the last 1 with the expression but with the array replaced with \(\alpha,\alpha,...,\alpha-1,...\). If the first entry is not 1, do the same thing with \(\{\uparrow\}\text{^}\) but with extra bits. The trailing 1 can be emitted. \(f(n)=n(\uparrow^n\{n\}^{\underset{n}{\underbrace{n,n,...,n}}}n)n)\) has growth rate \(f_{\omega^2+\omega}(n)\).
The limit of the \(\{\uparrow\}^{\lbrack\rbrack}\) is aforementioned \(n(\uparrow^n\{n\}^{\underset{n}{\underbrace{n,n,...,n}}}n)n)\). And this is exactly what the next extension will be.
The \(\{\}\) is equivalent to \(\{\}_1\). There are multiple pairs of braces, the n-th denoted \(\{\}_n\). If \(n>1\), \(a(@_a\{@_c\}_n@_b)b=a(@_a\{@_c\}_{n-1}^{\underset{n}{\underbrace{n,n,...,n}}}@_b)b\). To reduce confusion, one may move the subscript in \(\{\uparrow\}\text{^}\) by moving them after a \(:\)(colon). \(f(n)=n(\uparrow^n\{n\}_n^{\underset{n}{\underbrace{n,n,...,n}}}n)n\) has growth rate \(f_{\omega^2+\omega+1}(n)\).
The limit, again, is \(n(\uparrow^n\{n\}_n^{\underset{n}{\underbrace{n,n,...,n}}}n)n\). As the name suggest, this is extended in a same way as \(\{\uparrow\}^{\lbrack\rbrack}\).
The new formula is \(a(@_a\{@_c\}_{1,1,...,n,...}@_b)b=a(@_a\{@_c\}_{n,n,...,n-1,...}^{\underset{n}{\underbrace{n,n,...,n}}}@_b)b\). The function \(f(n)=n(\uparrow^n\{n\}_{\underset{n}{\underbrace{n,n,...,n}}}^{\underset{n}{\underbrace{n,n,...,n}}}n)n\) has growth rate \(f_{\omega^2+\omega2}(n)\).
Since the arrays introduced in \(\{\uparrow\}^{\lbrack\rbrack}\) and \(\{\uparrow\}_{\lbrack\rbrack}\) has the same definition, this can be extended by interpreting the arrays as linear arrays.
The array is now placed inside \(\lbrack\rbrack\) placed after the \(\{\}\). The top array from \(\{\uparrow\}^{\lbrack\rbrack}\) (\(^{n_1,n_2,...,n_k}\)) are \(\lbrack n_1,n_2,...,n_k\rbrack\). The linear arrays are seperated with \(\lbrack X\rbrack\), indicating the structure seperated. The array seperator other than comma(which is equivalent to \(\lbrack1\rbrack\)) are inside \(\lbrack\rbrack\).
The arrays that existed before (\(^{m_1,m_2,...,m_k}_{n_1,n_2,...,n_k}\)) are \(\lbrack m_1,m_2,...,m_k\lbrack X\rbrack n_1,n_2,...,n_k\rbrack\). \(n\times n\) array of \(n\) is \(\lbrack\lbrack X^2\rbrack n\rbrack\).
If multiple structures are seperated, like two \(\lbrack X\rbrack\), can be added(for the example, \(\lbrack2X\rbrack\)). There can also be different seperators like \(\lbrack X^2\rbrack\lbrack X\rbrack=\lbrack X^2+X\rbrack\). Note that if there are smaller seperator before larger one, the smaller one can be ommited if there are only \(1\)s inbetween, for example \(\lbrack X\rbrack\lbrack X^2\rbrack=\lbrack X^2\rbrack\).
If there are larger seperator before hand, also fill them with a corresponding structure.
Let \(\langle\alpha\rangle n\) denote \(\alpha\) array of \(n\). Generally, \(\lbrack\lbrack\alpha\rbrack n\rbrack=\lbrack\langle\alpha\rangle n\lbrack\alpha\rbrack n-1\rbrack\).
The rules of solving dimensional array:
The limit ended with \(\langle X^n\rangle n\). This can be continued via consept of superdimensions and trend to replace \(X\) with \(n\). Therefore, the next seperator is \(\lbrack X^X\rbrack\), equivalent to Hilbert Space seperator.
The next ofcource is \(\lbrack\lbrack X^{X+1}\rbrack n\cdots\rbrack=\lbrack\underset{n\;\langle X^X\rangle n\text{ s}}{\underbrace{\langle X^X\rangle n\lbrack X^X\rbrack\cdots\lbrack X^X\rbrack\langle X^X\rangle n}}\lbrack X^{X+1}\rbrack n-1\cdots\rbrack\), then \(\lbrack\lbrack X^{X+2}\rbrack n\cdots\rbrack=\lbrack n\;\langle X^X\rangle n\text{ s}\lbrack X^{X+2}\rbrack n-1\cdots\rbrack\).
This continues until \(\lbrack\lbrack X^{2X}\rbrack n\cdots\rbrack=\lbrack\langle X^{X+n}\rangle n\lbrack X^X\rbrack n-1\cdots\rbrack\) were the left side is filled with \(n\). It is now really difficult to describe this, but \(\lbrack X^{3X}\rbrack\) filles up to a \(\lbrack X^{2X+n}\rbrack\).
Here are the rules to solve these formulas inside \(\langle\rangle\), along with the previous formlae. The \(n\) come from the outside. Works on all levels.

|---|---|
| \(\lbrack\lbrack X^X\rbrack n\rbrack\) | \(\omega^\omega\) |

You already know what comes next, it's tetrational space! It is denoted \(\lbrack X\uparrow\uparrow X\rbrack\). Then \(\lbrack X\uparrow\uparrow\uparrow X\rbrack\), and then \(\lbrack X\uparrow^XX\rbrack\)!
