1. Introduction
This section is non-normative.
Bluetooth Low Energy (BLE) allows devices to broadcast advertisements to nearby observers. These advertisements can contain small amounts of data of a variety of types defined in [BLUETOOTH-SUPPLEMENT6].
For example, a beacon might announce that it’s next to a particular museum exhibit and is advertising with 1mW of power, which would let nearby observers know their approximate distance to that exhibit.
This specification extends [web-bluetooth] to allow websites to receive these advertisements from nearby BLE devices, with the user’s permission.
1.1. Examples
To discover what iBeacons are nearby and measure their distance, a website could use code like the following:
function recordNearbyBeacon( major, minor, pathLossVs1m) { ... } navigator. bluetooth. requestLEScan({ filters: [{ manufacturerData: { 0x004C : { dataPrefix: new Uint8Array([ 0x02 , 0x15 , // iBeacon identifier. 0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 // My beacon UUID. ])}}}], keepRepeatedDevices: true }). then(() => { navigator. bluetooth. addEventListener( ' advertisementreceived ' , event=> { let appleData= event. manufacturerData. get( 0x004C ); if ( appleData. byteLength!= 23 ) { // Isn’t an iBeacon. return ; } let major= appleData. getUint16( 18 , false ); let minor= appleData. getUint16( 20 , false ); let txPowerAt1m= - appleData. getInt8( 22 ); let pathLossVs1m= txPowerAt1m- event. rssi; recordNearbyBeacon( major, minor, pathLossVs1m); }); })
2. Privacy considerations
This section is non-normative.
Actively scanning for advertisements broadcasts a device address of the scanning device. If the UA’s Bluetooth system supports the privacy feature, this address rotates periodically, which prevents remote radios from tracking the user’s device. However, if the UA’s Bluetooth system does not support the privacy feature, this address is a stable unique identifier that’s difficult to change. To mitigate this, UAs should either use passive scanning, use the privacy feature in an observer, or warn the user that nearby devices will learn the identity of their device.
The ambient advertisements in a user’s area are unlikely to directly include GPS coordinates, but are likely to contain unique identifiers that could be manually correlated with particular physical locations or with particular other people. Given that, the user needs to give permission before a website gets access to nearby advertisements.
If a user has already given a site permission to know their location, it might be ok to implicitly grant access to BLE advertisements. However, BLE advertisements give away strictly less location information than full [geolocation-api] access, so UAs should allow users to grant that intermediate level of access.
BLE advertisements are usually fully public, since they’re broadcast unencrypted on 2.4GHz radio waves. However, it’s possible that a user would have a device broadcast private information in a radio-shielded room. This is probably an inappropriate use for BLE advertisements, but might argue for requiring explicit permission to scan, rather than inferring it from having permission to get a geolocation.
3. Security considerations
This section is non-normative.
Because this API doesn’t write anything, there are few if any security implications. A device in a shielded room might broadcast security-sensitive information, but we don’t have any actual attack scenarios for that.
4. Scanning for BLE advertisements

BluetoothLEScanOptions sequence <BluetoothLEScanFilterInit >;

options
requestLEScan()
summary navigator.bluetooth.
starts scanning for BLE advertisements,
asking the user for permission if they haven’t yet granted it. requestLEScan(options)
Because this could show a prompt, it requires a secure context, and UAs are likely to require a user gesture.
Advertising events that match a BluetoothLEScanFilter
in an active BluetoothLEScan
cause advertisementreceived
events to be dispatched
to the sending BluetoothDevice
.
A filter matches if the advertisement includes data equal to each present member.
Usually, you’ll only include one member in each filter.
Normally scans will discard
the second and subsequent advertisements from a single device
to save power.
If you need to receive them,
set keepRepeatedDevices
to true
.
Note that setting keepRepeatedDevices
to false
doesn’t guarantee you won’t get redundant events;
it just allows the UA to save power by omitting them.
In the rare case that you want to receive every advertisement without filtering them,
use the acceptAllAdvertisements
field.
The
method,
when invoked, MUST return a new promise promise and run the following steps in parallel: requestLEScan(options)
-
If
options.acceptAllAdvertisements
istrue
, andoptions.filters
is present, reject promise with aTypeError
and abort these steps.Note: There’s no need to include filters if all advertisements are being accepted.
-
If
options.acceptAllAdvertisements
isfalse
, andoptions.filters
is either absent or empty, reject promise with aTypeError
and abort these steps.Note: An empty set of filters wouldn’t return any advertisements.
- Let filters be

5. Event handling
5.1. Responding to advertising events
When the UA receives an advertising event event (consisting of an advertising packet and an optional scan response), it MUST run the following steps:
- Let device be the Bluetooth device that sent the advertising event.
-
For each
Bluetooth
instance bluetooth in the UA, queue a task on bluetooth’s relevant settings object’s responsible event loop to do the following sub-steps:- Let scans be the set of
BluetoothLEScan
s inbluetooth.
that match event.[[activeScans]]
- If scans is empty, abort these sub-steps.
- Note: the user’s permission to scan likely indicates that
they intend newly-discovered devices to appear in

. - Get the
BluetoothDevice
representing device inside bluetooth, and let deviceObj be the result. - Add each
BluetoothLEScan

- Let scans be the set of
An advertising event event matches a BluetoothLEScan
scan if the following steps return match

no match
. - Return

.
An advertising event event matches a BluetoothLEScanFilter
filter if all of the following conditions hold:
-
If
filter.name
is non-null
, event has a Local Name equal tofilter.name
.Note: A Shortened Local Name can match a
name
filter. - If
filter.namePrefix
is non-null
, event has a Local Name, andfilter.namePrefix
is a prefix of it. - If
filter.serviceUUID
is non-null
, it is equal to a Service UUID in event. - For each (id, filter) in
filter.manufacturerData
’s map entries, some Manufacturer Specific Data in event has a Company Identifier Code of id, and whose array of bytes matches filter. - For each (uuid, filter) in
filter.serviceData
’s map entries, some Service Data in event has a UUID whose 128-bit representation is uuid, and whose array of bytes matches filter.
6. Changes to existing interfaces
Instances of Bluetooth
additionally have the following internal slots:
| Internal Slot | Initial Value | Description (non-normative) |
|---|---|---|
[[activeScans]]
| An empty set of BluetoothLEScan instances.
| The contents of this set will have active equal to true .
|
Instances of BluetoothDevice
additionally have the following internal slots:
| Internal Slot | Initial Value | Description (non-normative) |
|---|---|---|
[[returnedFromScans]]
| An empty set of BluetoothLEScan objects.
| Used to implement keepRepeatedDevices .

7. Terminology and conventions
This specification uses a few conventions and several terms from other specifications. This section lists those and links to their primary definitions.
When an algorithm in this specification uses a name defined in this or another specification,
the name MUST resolve to its initial value,
ignoring any changes that have been made to the name in the current execution environment.
For example, when the requestLEScan()
algorithm says to call options.filters.map(filter=>new
,
this MUST apply the BluetoothLEScanFilter
(filter))Array.prototype.map
algorithm defined in [ECMAScript] with options.services
as its this
parameter and
the algorithm defined at BluetoothLEScanFilter()
as its callbackfn
parameter,
regardless of any modifications that have been made to window
, Array
, Array.prototype
, Array.prototype.map
, Function
, Function.prototype
, BluetoothLEScanFilter
, or other objects.

I've been troubleshooting some issues with Viasfora and noticed something that I definitely was not expecting:
It appears that if you implement an IClassifier
extension, and also implement IDisposable
, it will not be called by Visual Studio once the text buffer is released.
I have noticed this on Visual Studio 2013, but so far, I haven't fully verified if this is indeed the expected behavior, or if it is caused by something else I am doing. I do know of many other Visual Studio extensions that combine IClassifier
with IDisposable
, so if this turns out to be the default behavior, it could signal other extensions may be leaking resources.

There are many different tools available to engineers. Hand-calculations, spreadsheets, and code are all great ways to perform calculations or visualize data or concepts. MATLAB is the defacto tool to solve many engineering calculations, but is just too expensive to be a practical tool for many of us. Octave, Scilab, or Freelab are great alternatives, but is limited in scope to calculation. I began using python for calculations and visualizations and have found it to be a very powerful tool with many existing modules for mathematics and plotting, in addition to the thousands of other libraries for general computing.
API code to automate running of finite element models and reporting using python-pptx. Abaqus uses python as its native macro/scripting language, which makes it easy to develop powerful tools that utilize the robustness and simplicity of the python programming language.
This program was designed to generate a dynamic powerpoint presentation based on a user defined odb file. The abaqus.py
requires and abaqus license and can be run from the abaqus python console within Abaqus CAE. The abaqus_report.py
has many other modules that are not allowed in Abaqus python. PythonReportTool calls functions located in the AbaqusReportTool.py and can be run in any python console or windows terminal and can be executed by opening a windows command prompt by.
API code to automate cad in catia
specialized code to analyze composite plates using classical laminated plate theory
shear-bending diagrams, assisting hand calculations for stress
example code for computing finite element models for analysis and education

When using python, the very first code you will need is to import modules. An example of importing the essential scientific computing libraries with some settings is shown here.

2 teens burned during pot extraction, not Stead oven fire
RENO, Nev. (AP) - Reno fire officials say a kitchen fire at a house in Stead that originally was blamed on an exploding oven was started by two teenagers who were burning butane in a marijuana extraction process and suffered severe burns.
KOLO-TV reports the teenage boys whose names have not been released were flown to a burn center in Sacramento for treatment on Tuesday.
Authorities initially reported an oven explosion sparked the fire that left the house uninhabitable north of Reno Tuesday morning.
Fire officials said the teens reported the incident from a short distance away.
Reno police said they had significant burns to their hands and were told to stay in place for treatment but they left the scene. They were found later Tuesday.
An elderly woman’s hair was severely singed by the flames.
The incident remains under investigation.

Press release
Attainment rises and gap between disadvantaged pupils and peers continues to close in primary schools.
Attainment in primary schools has risen in every subject and disadvantaged pupils continue to close the gap on their peers - figures for primary tests out today (11 December 2014) show.
The results for more than half a million 11-year-olds (key stage 2) show the percentage achieving the expected level (level 4) in reading, writing and maths ( 3Rs ) has risen by 3 percentage points to 79% while the proportion achieving the more challenging level 4b is also up - from 63% to 67%.
Today’s figures also show the number of primaries below the floor has remained stable even though schools have been judged on a new tougher threshold.
Schools Minister David Laws said:
I am pleased to see that primaries have responded to the challenge of a higher floor standard - we have raised the bar and schools have raised their game.
It is also encouraging to see the attainment gap between disadvantaged children and their peers continue to narrow and parents, teachers and pupils deserve to be congratulated for their efforts.
But we know there is more to do and there are still too many areas with simply unacceptable levels of attainment for disadvantaged pupils.
We are committed to helping schools do more and have increased the pupil premium they receive per pupil to £1,300 so they have the resources they need.
While attainment has increased overall, disadvantaged pupils continue to close the gap on their peers:
This year, primary schools where fewer than 65% of pupils achieved at least the expected level (level 4) in the reading test, the maths test and teacher assessment of writing, and which were below the progress measures in all these subjects, are below the floor standard.
This year, a more challenging floor standard has been introduced - with the proportion of pupils required to reach the expected level rising by 5% (from 60% to 65%).
Despite this higher target, there are 768 schools below the floor - equivalent to 6% of state-funded mainstream schools - the same proportion as in 2013.
If primary schools were judged against last year’s floor standard only 469 schools would have been below the threshold - a reduction of almost 300 schools.
Today’s figures reveal that, once again, schools in London perform well both in general attainment and in closing the gap. However, local authorities around the country had significant success:
North Tyneside, Blackpool and St Helens are among 22 local authorities which had no schools below the floor
Trafford and Cheshire East are second and sixth respectively for local authorities with the highest proportions of pupils achieving the challenging level 4b in the 3Rs
Westminster and Camden had the highest proportion of disadvantaged pupils achieving the expected level in reading, writing and maths combined at 83% and 82% respectively
The government will continue to challenge schools to drive forward improvements. In 2016 primary schools will be judged on a new floor standard which will be equivalent to the more challenging level 4b. Schools will also be expected to have 85% of their pupils reaching this higher standard in reading, writing and maths.
There were 241 schools where 100% of pupils achieved the more challenging level 4b in reading, writing and mathematics this year.

Checkbox group editor allows users to select multiple values from a set of checkboxes. It provides similar functionality as Multiple Select editor, but requires some more space on the screen. The Display mode property allows you to place checkboxes one under the other or in a single row.


For cases when the objects included in the ConCoord distribution do not meet your coordination needs, ConCoord lets you convert your local Python objects into distributable objects very easily.
To walk through the ConCoord approach, you will use a different Counter object that increments and decrements by ten, namely tencounter.py. Once you install ConCoord, you can create coordination objects and save them anywhere in your filesystem. After you create tencounter.py, you can save it under /foo/tencounter.py:
class TenCounter:
def __init__(self, value=0):
self.value = value
def decrement(self):
self.value -= 10
def increment(self):
self.value += 10
def getvalue(self):
return self.value
def __str__(self):
return "The counter value is %d" % self.value
Once you have created the object, update your PYTHONPATH accordingly, so that the objects can be found and imported:
$ export PYTHONPATH=$PYTHONPATH:/foo/
Clients will use a proxy object to do method calls on the object. To create the proxy object automatically, you can use the following command:
$ concoord object -o tencounter.TenCounter
Usage: concoord object [-h] [-o OBJECTNAME] [-t SECURITYTOKEN] [-p PROXYTYPE] [-s] [-v]
-h, --help show this help message and exit
-o OBJECTNAME, --objectname OBJECTNAME client object dotted name module.Class
-t SECURITYTOKEN, --token SECURITYTOKEN security token
-p PROXYTYPE, --proxytype PROXYTYPE 0: basic, 1: blocking, 2: client-side batching, 3: server-side batching
-s, --safe safety checking on/off
-v, --verbose verbose mode on/off
This script will create a proxy file under the directory that the object resides (i.e. /foo/):
/foo/tencounterproxy.py := the proxy that can be used by the client
IMPORTANT NOTE: ConCoord objects treat __init__ functions specially in two ways:
__init__ without any arguments. Therefore, while implementing coordination objects, the __init__ method should be implemented to be able to run without explicit arguments. You can use defaults to implement an __init__ method that accepts arguments.
the Client-Replica connection. This way, multiple clients can connect to a ConCoord instance without reinitializing the object. During proxy generation, the original __init__ function is renamed as __concoordinit__, to reinitialize the object the user can call __concoordinit__ at any point.
After this point on, you can use TenCounter just like we use Counter before.
You can create bundles to use at the server and client sides using the Makefile provided under concoord/
Remember to add the objects you have created in these bundles.
To create a bundle that can run replica, acceptor and nameserver nodes:
$ make server
To create a bundle that can run a client and connect to an existing ConCoord instance:
$ make client
We have two kinds of loggers for ConCoord:
Both of these loggers are included under utils.py. To start the NetworkLogger, use the logdaemon.py on the host you want to keep the Logger.
ConCoord provides a distributed and fault-tolerant threading library. The library includes:
The implementations of distributed synchronization objects follow the implementations in the Python threading library. We will walk through an example below using the Semaphore object under concoord/object/semaphore.py
In the blocking object implementation, the method invocations that use an object from the threading library requires an extra argument _concoord_command. This argument is used by the calling Replica node to relate any blocking/unblocking method invocation to a specific client. This way, even if the client disconnects and reconnects, the ConCoord instance will remain in a safe state.
from concoord.threadingobject.dsemaphore import DSemaphore
class Semaphore:
def __init__(self, count=1):
self.semaphore = DSemaphore(count)
def __repr__(self):
return repr(self.semaphore)
def acquire(self, _concoord_command):
try:
return self.semaphore.acquire(_concoord_command)
except Exception as e:
raise e
def release(self, _concoord_command):
try:
return self.semaphore.release(_concoord_command)
except Exception as e:
raise e
def __str__(self):
return str(self.semaphore)
To create the proxy for this blocking object we will use the following command:
$ concoord object -o semaphore.Semaphore -p 1
This command creates the proxy that supports blocking operations. Now you can use blocking objects just like basic ConCoord objects. First, we start the replica, acceptor and nameserver nodes the same way we did before as follows:
$ concoord replica -o semaphore.Semaphore -a <IP_ADDRESS> -p 14000
$ concoord acceptor -b <IP_ADDRESS>:14000
$ sudo concoord nameserver -n semaphoredomain -o semaphore.Semaphore -b <IP_ADDRESS>:14000 -t 1
To test the functionality, you can use multiple clients or print out the Semaphore object as follows:
>>> from semaphoreproxy import Semaphore
>>> s = Semaphore("<IP_ADDRESS>:14000")
>>> s.acquire()
True
>>> i = 10
>>> i += 5
>>> s
<DSemaphore count=0>
>>> s.release()
>>> s
<DSemaphore count=1>
>>>

- prismAxis – axis of the prism (can be equal to ‘X’, ‘Y’, ‘Z’)
- setName – name of the set to be generated


We have undertaken to begin posting a series of tutorials on the XC software in order to pave the way for those who want to join the project.
Motivation.- Our main motivation is to create an open, powerful, robust and flexible tool, which gives the users a great control over the calculation process, since they can freely study, modify, and customize it to fit their needs, and, of course, contribute to the community with their own developments.
Inspiration.- The growth of free software is exponential, which has given rise to communities as powerful as Linux, LibreOffice or Mozilla. On a smaller scale, one of the free software projects from which we often seek inspiration is FreeCAD, a parametric 3D modeling CAD that began in 2001 and has an active community of collaborators that currently works, inter alia, in the development of a BIM for the program.
Where are we?.- XC incorporates OpenSees kernel as its FE calculation engine. As is common in finite element programs, XC has modeling tools (2D and 3D geometry entities, boolean operations, cable modeling, automatic meshing, selecting tools, ...), loads and boundary conditions, linear and non-linear structural analysis, generation of combinations, verification of limit states according to different standards, postprocessing tools, ...
Where do we want to drive the development?.- Wherever the collaborative network wants: form finding, IFC structural, sophisticated prestressing analysis, fire engineering,... XC is not a one-way program, its growth depends on the enhancements and new features that the developer community incorporates.


Discussion
The focus of this study is the chronology, distribution, and form of Rosegate points; however, the results of this analysis and the available data on Fremont projectile points open additional avenues for future research. As the projectile point data demonstrates, multiple styles are the norm at Fremont sites. Rosegate points were found throughout the region, but after the introduction of side-notched and other point types they were rarely the most common style. Can the differences be explained by functional concerns? Hunting and warfare have different functional requirements and are likely causes of the simultaneous use of different styles in some cases (Loendorf et al. 2015). Yet functional requirements are unlikely to be responsible for the spatial variation noted in this analysis. Stone projectile points are almost exclusively used for large game or warfare (Ellis 1997). Big game animals may vary in quantity throughout the Fremont region, but the same types of large mammals (deer, pronghorn, elk, etc.) are found throughout. Thus, there is little reason for stone projectile points to vary in style exclusively for hunting purposes without reference to the historical trajectories of their makers. Projectile points are associated with various social and symbolic functions in nearby areas of the Southwest (Bayman 2007:78–79; Beaglehole 1936; Cushing 1883; Dittert 1959; Fewkes 1898; Justice 2002b:309–310; Kaldahl 2000; Kamp et al. 2016; Parsons 1932, 1939; Russell 1908; Sedig 2014; Simpson 1953; Stevenson 1884, 1894, 1903; Whittaker and Kamp 2016). Certainly, several aspects of social behavior influence the form of a projectile point. These behaviors can form recognizable patterns that may provide new ways to study the Fremont when combined with additional data.
Projectile points are often used as markers of social identity by archaeologists (e.g., Mason 1894:655; Waguespack et al. 2009:787; Whittaker 1994:260–268). For example, Desert Side-notched points are associated with the Numic people (Bettinger and Baumhoff 1982; Delacorte 2008). Ethnographic research supports this association (e.g., Clark 2001:6–22; Garfinkel 2007; Wiessner 1983). This identity is caused either by an association between an identifiable point form and a self-identified social group or because individuals learned knapping in the same communities of practice (Lave and Wenger 1991; Wenger 1998). However, projectile point styles often seem to cross archaeologically defined borders (Holmer and Weder 1980:67–68; Simms 1990:4), which complicates the use of projectile points as markers of identity. Jones (1994:73) points out that the widespread distribution of Rosegate points indicates the makers likely did not share ethnicity or language. Nevertheless, artifacts do not have to be specific to only one social group to be used to be associated with identity. Objects can be actively used to signal identity, as in emblemic style (Wiessner 1983), but in many cases, objects may be associated with a particular social group merely through association in a particular context. For example, Curta (2007:174) notes that medieval brooch styles in Hungary differ between the east and the west: eastern style brooches resemble brooches in Italy, whereas western brooches resemble styles in Germany and France. Thus, the brooches are associated with Hungarian identities and are useful contextual information, but they are not exclusive to Hungary. A recent study found that the distribution of projectile point types most likely corresponds to the area covered by speakers of a group of related languages, rather than any smaller social unit (Buchanan et al. 2019), thus recognizable ethnic groups would probably be too small to have a unique style. In summary, projectile point types likely reflect social identity at some level, although the association may be quite broad and may cross the social boundaries of smaller units.
If projectile points can be used to define distinct material complexes, then perhaps the introduction of various new point types sometime between AD 800 and 1000 may represent an influx of people from other regions (Allison 2019; Janetski 1993; see Madsen and Simms 1998 for a general discussion of Fremont origins). The number and size of sites dating after this period are significantly higher than before and suggest that some migration occurred.
Projectile points have been used previously to argue for migration in the Fremont region. For example, Holmer and Weder (1980:68) cite several arguments using projectile point types for the movement of people from the Plains and Ancestral Pueblo regions. They argue that the projectile point data in their analysis support both hypotheses. They also suggest that matrilocality provides an explanation for the multiplicity of styles found in Fremont sites. If men practiced in a particular knapping style often moved to new villages, then it would intuitively create this pattern—a possibility worth exploring although it would likely require reference to other types of material culture. Because Rosegate points are never replaced but continue to be manufactured and used until the end of the Fremont period, these points may be representative of descendants of Great Basin Archaic peoples whose ancestors had long inhabited the Fremont region. The spatial analysis suggests that some areas had much higher or lower percentages of Rosegate points than would be expected if the points were distributed evenly. Areas with high percentages of Rosegate points may be places where in-migration was less frequent. This explanation is appealing but requires evidence, as Rosegate points and similar points are widespread, including in the Southwest.

what is thymol?
Thymol is a client-side JavaScript implementation of Thymeleaf, the popular server-side Java template engine.
Thymol 2.0 provides the facility to prototype Thymeleaf 2.1 template based designs without having to run a web application server.
You don't need to be running tomcat or jetty or any other servlet engine, you can do everything on your local file system or network file server or use a plain old web server (like Apache) if you wish.
(Incidentally this site is built using Thymol. To find out how go here.)
how is it licensed?
Thymol is Open Source Software and is distributed under the terms of the Apache License 2.0.
why write it?
Thymol was originally created in order to provide a more accurate static representation of Thymeleaf's dynamic templating capabilities by offering support for Thymeleaf attributes through a statically accessible JavaScript library.
Subsequently Thymol has evolved into a highly capable prototyping system for Thymeleaf based designs.
To read more about why Thymol was started see the static imports page.
how does it work?
At the basic level it can be very simple: you add a single script tag to your Thymeleaf template and load that template directly into your browser.
what about the name?
Thymol is the informal name of the organic molecule 2-isopropyl-5-methylphenol, this chemical provides most of the flavour of the thyme leaf.
Thymol implements most of the functionality of Thymeleaf but doesn't require the use of a server or even a JVM.


1 Enough, then, of Homer and the Cyprian poems. But, when I asked the priests whether the Greek account of what happened at Troy were idle or not, they gave me the following answer, saying that they had inquired and knew from Menelaus himself.
2 After the rape of Helen, a great force of Greeks came to the Trojan land on Menelaus' behalf. After disembarking and disposing their forces, they sent messengers to Ilion, one of whom was Menelaus himself.
3 When these were let inside the city walls, they demanded the restitution of Helen and of the property which Alexandrus had stolen from Menelaus and carried off, and they demanded reparation for the wrongs; but the Trojans gave the same testimony then and later, sworn and unsworn: that they did not have Helen or the property claimed, but all of that was in Egypt, and they could not justly make reparation for what Proteus the Egyptian had.
4 But the Greeks, thinking that the Trojans were mocking them, laid siege to the city, until they took it; but there was no Helen there when they breached the wall, but they heard the same account as before; so, crediting the original testimony, they sent Menelaus himself to Proteus.


Put down that phone! Indonesians invent device to aid internet-addicted
by ReutersJAKARTA: From browsing social media to watching videos and chatting with friends, Indonesian university student Tyas Sisianindita spends about eight hours a day on her phone.
“I realise that I am addicted,” the university student admitted, saying she checks her phone continuously from the time she wakes up, even when she is in classes.
“At night, when I can’t sleep, I can use my phone for up to five hours.”
A group of fellow students at the University of Indonesia, led by inventor Irfan Budi Satria, has spent three months developing a wearable device that can help internet users like Sisianindita cut down on the time they spend flicking at their phones.
Called “Nettox”, from “internet detox”, the device is worn on the wrist and contains a pulse oximeter sensor that measures hemoglobin oxygen levels and heart rate variability (HRV).
Studies have found that prolonged mobile phone usage has a specific lowering effect on HRV levels. The Nettox device emits a sound when HRV and blood oxygen levels fall within this range, which reminds the wearer to stop using their phone.
For people aged between 18 and 25, the HRV should ideally stay above 60, according to the American Psychological Association, Satria said.
At a recent trial, Sisianindita’s HRV reading was 44.
Internet addiction is a growing social issue in Indonesia. In October, two teenagers were treated for their addiction to internet gaming, media reported.
“Children must be taught to be more active and take part in extracurricular activities,” said psychologist Kasandra Putranto.
Satria’s team is working on personalising Nettox and improving its accuracy as HRV readings can vary depending on a person’s body shape, gender and health conditions.
They aim to apply for a patent for their invention with the university by next year.
Satria says, though, that Nettox is targeted at those already invested in changing their behavior.
“Our goal is to help the health-conscious,” he said.
“To help people who want to free themselves from internet addiction.”

Preface
When I first thought about writing this book,
I immediately thought of O'Reilly & Associates to publish
it. They were the first publisher I contacted, and the one I
most wanted to work with because of their tradition of books
covering "just the facts." This approach is not what one
normally thinks of in connection with books on data structures
and algorithms. When one studies data structures and
algorithms, normally there is a fair amount of time spent on
proving their correctness rigorously. Consequently, many books
on this subject have an academic feel about them, and real
details such as implementation and application are left to be
resolved elsewhere. This book covers how and why certain data
structures and algorithms work, real applications that use
them (including many examples), and their implementation.
Mathematical rigor appears only to the extent necessary in
explanations.
Naturally, I was very happy that O'Reilly
& Associates saw value in a book that covered this aspect
of the subject. This preface contains some of the reasons I
think you will find this book valuable as well. It also covers
certain aspects of the code in the book, defines a few
conventions, and gratefully acknowledges the people who played
a part in the book's creation.

My server is maded with NodeJS and Express; well thats all...
I like this way of creating web pages (With NodeJS), Im working in other project very similar to this, but is with the famous MERN stack
I like to see my code in GitHub ;3
I wrote this on September 1, 2021


About me
- Developer at Hook 42
- Swimming, cats, and the internet
The Thought Behind the Talk
I had to create a custom module for the first time, and I had only modified code in the past
I didn't want to just know how to make a custom module, I wanted to know the answers to all my why questions
Quick note: sometimes words are mentioned before they are defined. Please have patience.
Do you need a custom module?
- 5,500 + Drupal 8 contrib modules with security updates and help from the Drupal universe
- Might have a unique problem that contrib doesn't solve
- Contrib module might be too bulky and hurt site performance
- Bring in the functionality of many contrib modules into one custom module
We can't just start with the list of files
Nothing is ever that easy.
PSR-4: Improved Autoloading
- PSR stands for PHP Standard Recommendation
- PSR is a PHP specification that is published by the PHP Framework Interop Group (php-fig) who's focus is to move "PHP foward through collaboration and standards"
- Drupal 8 implements the PSR-4 standard for namespaces and autoloading
- PSR-4: "Autoloaders remove the complexity of including files by mapping namespaces to file system paths."
Autoloading
- Autoloading is the capability of loading and linking portions of a program automatically when needed. The autoloader searches through a path of directories and finds the code that defines the subroutine (method/function).
- Autoloading means your code does not need to include a long list of source files in your php file
- The magic of autoloading works because of namespacing
Namespacing
- "Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts." - Wikipedia
- Namespacing helps you avoid name collisions if you repeat the name for a function/class that was declared before
- Eliminates need for super long class names, points to where in the code you can find the function source
Composer
-
Dependency/package manager: software the automates the process of installing, upgrading, configuring and removing software.
-
Composer is a dependency manager for PHP, that assists with locating, downloading, validating, and loading packages and ensures you have the correct package version
Symfony
- Symfony is a PHP framework and a set of reuasable PHP components and libraries
- Defined as a MVC (Model, View, and Controller) framework
- Components are standalone PHP libraries that generate specific features
Some Symfony Components
- ClassLoader: provides tools to autoload classes and cache their locations for performance
- Console: helps you create command line interfaces
- CssSelector: converts CSS selectors to XPath (XML Path language) expression
- DependencyInjection: lets you standardize and centralize the way objects are constructed
- EventDispatcher: lets components communicate with each other
- HttpFoundation: defined an object-oriented layer for the HTTP specification
- HttpKernel: converts a HTTP Request into a HTTP Respose by using a EventDispatcher component
- Process: executes commands in subprocesses, creates API for shell executions
- Routing: maps an HTTP request to a set of configurable variables
- Serializer: turn objects into specific formats (YAML) and specific formats into objects
- Translation: provides tools for internationalization
- Validator: validates following JSR 303: Bean Validation
- Yaml: parses YAML strings to conver them to PHP arrays, and vice versa
Why are you telling me this?
-
Autoloading and namespacing play an important role in how and why we structure files and code in a module
-
While Drupal Core uses Composer, you can also manage dependencies for your custom module with Composer
-
While Drupal 8 does NOT use the Symfony framework, D8 uses some Symfony components
Types of files:
- YAML (YAML Ain't Markup Language): .yml, .yaml
- PHP - Hypertext Preprocessor: .php
- Markdown: .md
- Javascript Object Notation (JSON): .json
- Module: .module
- Javascript: .js
- CSS (Cascading Style Sheets): .css
Naming the module
- Start with a letter
- Use only lower-case letters and underscores
- No spaces
- Unique name
- Does not contain any reserved words: src, lib, vendor, assets, css, files, images, js, misc, templates, includes, fixtures, Drupal

capable.info.yml
- The info.yml file lives in your root folder and tells Drupal about your module
- The info.yml file information can be found on the Drupal admin pages (/admin/modules)
- Technically, the only required file in your module (although the module won't do anything)
capable.info.yml
What's going on?
capable.info.yml
/admin/modules
capable.info.yml complete example
capable.info.yml
-
depedencies:
- List the other module(s) that your module depends on to work.
- Namespacing: {project}:{module}
- {project} is the name as it appears in the Drupal.org url (https://www.drupal.org/project/token)
- {module} is the module machine name (token)
- Can also include version restrictions: token:token (8.x-1.3)
-
test_dependencies:
- List the module(s) you need to run automated tests
- Same namespacing as dependecies: {project}:{module}
-
configure:
- Specify the route to a configuration form
- This will show on the /admin/modules pages when you expand [this needs different words or an image]
-
php:
- Defines the minimum PHP verison that your module requires
- Can't enable the module if your PHP version is older
-
hidden:
- hidden: true, will hide your your module on the /admin/modules page
- Why would you hide your module? Perhaps it only implements tests and you don't want it disabled
The Controller File
- Following PSR-4, the controller file will live inside a folder called src, and then in a folder called Controller
- src stands for source
capable/src/Controller/CapableController.php
- Need to declare a namespace at the top.
- Namespace format: Drupal\[module name]\Controller;
- The controller file will work with the router file
CapableController.php
CapableController.php
-
namespace Drupal\capable\Controller: declaring the namespace for the capable Controller class
- this must be done before any other code (except a declare statement)
-
use Drupal\Core\Controller\ControllerBase: importing (aliasing) the Drupal core ControllerBase, which is being extended by CapableController class.
- Do not include a leading \
- Only specify one class per use statement.
- No clear rule to order for multiple use statements.
- Final use statement should habe a blank line underneath it.
-
class CapableController extends ControllerBase: creation of CapableController class that extends Drupal's core ControllerBase class
-
public function content(): take note of the name of the function, this will come back in the routing file
The Routing File
- A route is a path where Drupal returns some sort of content
- The router determines which code should be run to generate the response.
- The routing system is responsible for matching paths to controllers.

Parameters in Routes
- Parameters are used for URLs that may contain dynamic values.
/parameters/[partial] would work for both /parameters/hello and /parameters/goodbye
- The [partial] element in the url is called a slug, and is is avaible as a $partial in the controller method
- You can even have multiple parameters on a single route: product/[productnumber]/[color]

The capable.module file is optional
-
Used for implementing hooks
Introduction to Hooks
-
Hooking: range of techniques that lets you change the behavior of applications by intercepting events passed between software components.
-
Hook: the code that handles this interception
-
Hooks in Drupal let modules interact with other modules or Drupal core
-
Hooks can be thought of event listeners that fire off when a certain event triggers them, and can be used at various code execution points
-
In Drupal 8, some hooks have remained the same, some have been removed, others have been modified, and some have been added. For the entire list of core hooks, click here.
-
To implement a hook, replace the hook name of the function with the name of your module:
capable.module
capable/capable.module
capable.module
/admin/help/capable
Composer
-
If your module has a dependency to a third party library hosted on Packagist, you can define this dependency
-
MUST declare dependencies in your info.yml file, but composer.json can let you get more specific with constraints
-
If your module does not have any dependencies, composer.json is not required, but having it will not have a negative impact
-
Drupal core will NOT automatically find your custom module composer.json,
Tell root composer.json about your custom module's composer.json
- 1. In root composer run
composer require wikimedia/composer-merge-plugin
- 2. Edit root composer file
root/composer.json
Capable composer.json
- 3. create custom module composer file
capable/composer.json
Composer File

Forms
-
Introduction to Form API
-
API: application programming interface is a set of functions and tools for building software with clearly defined methods of communication
-
Need to identify the type of form you need
-
General form: extend Form Base
-
A configuration form that lets administrators update a module settings: extend ConfigFormBase
-
A form for deleting content or configuation with a confirmation step: extend ConfirmFormBase
-

Configuration is a place to store information you would like to synchronize from development to production. This information can be used in your own plugins, entities and settings.
-
Lives under a /config directory
-
/install directory
-
Configuration defaults live under the /config/install directory
-
capable.settings.yml: This file stores configuration defaults, which are assigned to the correct fields via the next file
-

Plugins and Custom Blocks
-
Plugins are small pieces of functionality that are swappable
-
Plugins that perform similar functionality are of the same plugin type
-
Blocks are instances of the block plugin.
-
Plugin code must live in /src/Plugin/[plugin_type]/Example.php
-
Blocks: /src/Plugin/Block/*

Libraries
-
A library is a "collection of implementations of behavior... that has a well-defined interface by which the behavior is invoked." - Wikipedia
-
Define one or more libraries (assets) in [modulename].libraries.yml
-
Must explicitly tell Drupal the libraries you want it to load, including CSS and JS files
-
Drupal 8 no longer loads jQuery on all pages on default, so you must tell Drupal that your library has a dependency on jQuery.
