FAQ
After connected, AutoConnect menu performs but no happens.¶
If you can access the AutoConnect root path as http://ESP8266IPADDRESS/_ac from browser, probably the sketch uses ESP8266WebServer::handleClient() without AutoConnect::handleRequest().
For AutoConnect menus to work properly, call AutoConnect::handleRequest() after ESP8266WebServer::handleClient() invoked, or use AutoConnect::handleClient(). AutoConnect::handleClient() is equivalent ESP8266WebServer::handleClient combinated AutoConnect::handleRequest().

An esp8266ap as SoftAP was connected but Captive portal does not start.¶
Captive portal detection could not be trapped. It is necessary to disconnect and reset ESP8266 to clear memorized connection data in ESP8266. Also, It may be displayed on the smartphone if the connection information of esp8266ap is wrong. In that case, delete the connection information of esp8266ap memorized by the smartphone once.
Does not appear esp8266ap in smartphone.¶
Maybe it is successfully connected at the first WiFi.begin. ESP8266 remembers the last SSID successfully connected and will use at the next. It means SoftAP will only start up when the first WiFi.begin() fails.
The saved SSID would be cleared by WiFi.disconnect() with WIFI_STA mode. If you do not want automatic reconnection, you can erase the memorized SSID with the following simple sketch.
#include <ESP8266WiFi.h> void setup() { delay(1000); Serial.begin(115200); WiFi.mode(WIFI_STA); delay(100); WiFi.begin(); if (WiFi.waitForConnectResult() == WL_CONNECTED) { WiFi.disconnect(); while (WiFi.status() == WL_CONNECTED) delay(100); } Serial.println("WiFi disconnected."); } void loop() { delay(1000); }
You can interactively check the WiFi state of ESP8266.
Please try ESPShaker. It is ESP8266 interactive serial command processor.
Does not response from /_ac.¶
Probably WiFi.begin failed with the specified SSID. Activating the debug printing will help you to track down the cause.
How change esp8266ap for SSID name in Captive portal?¶
An esp8266ap is default SSID name for SoftAP of captive portal and password is 12345678. You can change both by using AutoConnectConfig.
How change HTTP port?¶
HTTP port number is defined as a macro in AutoConnect.h header file. You can change it directly with several editors and must re-compile.
#define AUTOCONNECT_HTTPPORT 80
Hang up after Reset?¶
If ESP8266 hang up after reset by AutoConnect menu, perhaps manual reset is not yet. Especially if it is not manual reset yet after uploading the sketch, the boot mode will stay 'Uart Download'. There is some discussion about this on the Github's ESP8266 core: https://github.com/esp8266/Arduino/issues/1017
If you received the following message, the boot mode is still sketch uploaded. It needs to the manual reset once.
ets Jan 8 2013,rst cause:2, boot mode:(1,6) or (1,7) ets Jan 8 2013,rst cause:4, boot mode:(1,6) or (1,7) wdt reset
The correct boot mode for starting the sketch is (3, x).
How erase the credentials saved in EEPROM?¶
Make some sketches for erasing the EEPROM area, or some erasing utility is needed. You can prepare the sketch to erase the saved credential with AutoConnectCredential. The AutoConnectCrendential class provides the access method to the saved credential in EEPROM and library source file is including it.
A class description of AutoConnectCredential is follows.
Include header¶
#include <AutoConnectCredential.h>
Constructor¶
AutoConnectCredential();
AutoConnectCredential default constructor. The default offset value is 0. If the offset value is 0, the credential storage area starts from the top of the EEPROM. AutoConnect sometimes overwrites data when using this area with user sketch.
AutoConnectCredential(uint16_t offset);
Specify offset from the top of the EEPROM for the credential storage area together. The offset value is from 0 to the flash sector size.
Public member functions¶
-
uint8_t entries()
Returns number of entries as contained credentials. -
int8_t load(const char* ssid, struct station_config* config)
Load a credential entry specified ssid to config. Returns -1 as unsuccessfully loaded. -
bool load(int8_t entry, struct station_config* config)
Load a credential entry to config. The entry parameter specify to index of the entry. -
bool save(const struct station_config* config)
Save a credential entry stored in config to EEPROM. Returns the true as succeeded. -
bool del(const char* ssid)
Delete a credential entry specified ssid. Returns the true as successfully deleted.
Data structures¶
- station_config
A structure is included in the ESP8266 SDK. You can use it in the sketch like as follows.
extern "C" { #include <user_interface.h> }
struct station_config { uint8 ssid[32]; uint8 password[64]; uint8 bssid_set; uint8 bssid[6]; };
- EEPROM data structure
A data structure of the credential saving area in EEPROM as the below. 1
| Byte offset | Length | Value |
|---|---|---|
| 0 | 8 | AC_CREDT |
| 8 | 1 | Number of contained entries (uint8_t) |
| 9 | 2 | Container size, excluding size of AC_CREDT and size of the number of entries(width for uint16_t type). |
| 11 | variable | SSID terminated by 0x00. Max length is 32 bytes. |
| variable | variable | Password plain text terminated by 0x00. Max length is 64 bytes. |
| variable | 6 | BSSID |
| variable | Contained the next entries. (Continuation SSID+Password+BSSID) | |
| variable | 1 | 0x00. End of container. |
Hint
With the ESPShaker, you can access EEPROM interactively from the serial monitor, and of course you can erase saved credentials.
How locate the link button to the AutoConnect menu?¶
Link button to AutoConnect menu can be embedded into Sketch's web page. The root path of the menu is /_ac by default and embed the following
tag in the generating HTML.
MENU
How much memory does AutoConnect consume?¶
Sketch size¶
It increases about 53K bytes compared to the case without AutoConnect. A sketch size of the most simple example introduced in the Getting started is about 330K bytes. (270K byte without AutoConnect)
Heap size¶
It consumes about 2K bytes in the static and about 12K bytes are consumed at the moment when menu executed.
I cannot complete to Wi-Fi login from smartphone.¶
Because AutoConnect does not send a login success response to the captive portal requests from the smartphone. The login success response varies iOS, Android and Windows. By analyzing the request URL of different login success inquiries for each OS, the correct behavior can be implemented, but not yet. Please resets ESP8266 from the AutoConnect menu.
-
There may be 0xff as an invalid data in the credential saving area. The 0xff area would be reused. ↩

This response to the AUTH command indicates that the selected
authentication mechanism may only be used when the underlying SMTP
connection is encrypted. Note that this response code is documented
here for historical purposes only. Modern implementations SHOULD NOT
advertise mechanisms that are not permitted due to lack of
encryption, unless an encryption layer of sufficient strength is
currently being employed. |

Output string streams are always dynamic. The str() function does not have the functionality of freezing the string stream anymore. Instead, the string returned from str() is a copy of the internal buffer. The string passed to the overload of str() that takes an argument is copied into the internal buffer, not used as the internal buffer. If you need to influence a string stream's internal buffering, you must do it through the pubsetbuf() member function of std::basic_streambuf.
The classes strstream, istrstream, ostrstream, and strstreambuf are deprecated features in the standard iostreams. They are still provided by this implementation of the standard iostreams, but may be omitted in the future when they are removed from the C++ standard.

The method I am choosing to write about is .collect. Collect is (as far as I can tell) an alias for map. That is, I think they do the same thing. I can't really find anything online that suggests that they are not the same, and in the various code I've looked at on stack overflow they seem to do the same thing. All of that is pretty irrelevant, though, since I'm not writing about map.
What it does is returns a new array (so it is not destructive!) that has as elements the results of running the code block on the original element. That's a mouth full, and it's hard to see what exactly is doing what, so I'm going to break it down a little bit.
# def separate_comma(number)
# number = number.to_s.chars.to_a
# number = number.reverse.each_slice(3).collect {|a| a.join('')}
# number.join(',').reverse
# end
This is a little snippet of code from a challenge I worked on this week. Whats actually going on here is collect is iterating through each element (a)i n the array I used it on and joining them together to form with '' so that they are right next to each other. The end result is that I end up with a string which is a joining of all the elements in the original array.

property TableSize: Integer;
TableSize determines the size of the table used in GetSample for kmTableNearest and kmTableLinear kernel modes.
For kmTableNearest the weightcurve of the kernels is quantized in proportional to the tablesize. Perceptually the side effect of the table nearest approach, becomes visible as the tablesize decreases. With a table size of 2, the actual result becomes similar to using the box kernel.
For kmTableLinear the weightcurve of the kernels is approximized via linear interpolation between the quantized values in the table. Perceptually the side effect of the table linear approach, becomes visible as the table size decreases. With a table size of 2, the actual result becomes similar to using the linear kernel.

collocated with the Eighth Swedish Language Technology Conference (SLTC), University of Gothenburg, Sweden
25th November 2020
The workshop will be held online.
Workshop description
All areas of natural language processing have achieved visible breakthroughs from the use of data-driven models. Contemporary machine learning is significantly influenced by techniques that rely on large datasets that demand substantial computational resources to solve practical problems in a tangible way (e.g. models based on transformers such as BERT, VilBERT, ALBERT, and GPT-2 that are pre-trained on large corpora of unlabelled data).
However, many of the world’s languages lack the availability of linguistic description as well as of sufficiently large computer-readable corpora of linguistic material. Even those languages that are considered well-resourced have some domains where resources are scarce, for example corpora of dialogue and situated interaction. Another similarity of these domains with under-resourced languages is that since they focus on spoken or spoken-like interaction (either in a written or an audio form) they show a high variability of input data. Applying state-of-the-art deep-neural-network-based methods for the development of data-driven systems in such resource-constrained environments is a non-trivial task.
For this workshop, we encourage contributions in the area of resource creation and representation learning in limited or low-resource environments that are tackling the above mentioned problems. In particular we would like to open a forum by bringing together students, researchers, and experts to address and discuss the following questions:
- How can new resources be constructed or extended for languages and domains that lack standardised representations of linguistic units?
- What experience from building resources for languages that have a good coverage today (for example Scandinavian languages) can be ported to building resources for under-resources languages and domains?
- How to deal with the variability of data and its standardisation in machine learning approaches?
- What algorithms and methods can we employ to transfer learning from related domains/languages that have good coverage?
- What is the role of multi-task learning in this domain?
- What representations can be learned and how effective are they in different low-resource scenarios?
- How can newly created resources and learned representations be evaluated?
- What ethical considerations are involved?
Intended participants are researchers, PhD students and practitioners from diverse backgrounds (linguistics, computational linguistics, speech, machine learning etc). We foresee an interactive workshop with plenty of time for discussion, complemented with invited talks and short presentations of on-going or completed research.
Submission
We invite submissions of 2-page extended non-anonymous abstracts with any number of pages for references using the ACL/EMNLP template. Papers related to our theme and already presented at other venues or have already been published elsewhere will be considered for acceptance for presentation as well. The abstracts will be reviewed by the workshop organisers and the accepted ones will be posted on the website, unless authors wish not to do so. There will be no workshop proceedings but post-proceedings may be organised depending on the interest of authors.
Extended abstracts should be submitted in the pdf format at https://easychair.org/conferences/?conf=resourceful2020

Roads are one of the most important routing communication channels today. People in India commute daily to different places such as for work, schools, gyms, shopping etc. using these network of roads. It is estimated that India has about 5,603,293 kilometres of road network, SECOND in India! Even with their higher importance, they does not receive the quality management by the government they deserve. The below bar chart shows the quality condition about the roads in different locations on India. The metrics plotted are total number of roads that are unfit for local commute and transportation.
Plastics are chemicals that are toxic in nature and are almost indecomposible. Since previous yearsm there has been reckless production of plastic, and since it cannot be decomposed, the plastic that is already produced, is simply a piece of crap. The below geospatial data demonstrates the location wise distribution of plastic production units in India.
You can hover over the data points to see how exorbitantly huge these numbers are.

Memory Dumps
I’ve been looking at memory dumps often lately. Since I usually (always) debug with ‘printf’, I needed a better visual for my memory dumps. I decided to do a simple memory dumper:
And added some features:
- Colored output
- Different data types (hex, decimal, …)
- You can specify different regions with different colors and sub-regions
- Print actual data values
- Array elements alternate between bold and normal styles
- Display cache alignment
Here is a example:
// Example struct
struct S {
vec3 v;
point2 p;
};
// Array of S elements
S v[3] = {{{1, 2, 3}, {4, 5}},
{{10, 20, 30}, {40, 50}},
{{100, 200, 300}, {400, 500}}};
// Here we can define a different region for each struct field:
auto layout = MemoryDumper::RegionLayout().withSizeOf<S>(3)
.withSubRegion(vec3::memoryDumpLayout().withColor(ConsoleColors::blue))
.withSubRegion(point2::memoryDumpLayout().withColor(ConsoleColors::yellow));
// Dump to console with colors and data values
MemoryDumper::dump(v, 3, 8, layout,
memory_dumper_options::type_values |
memory_dumper_options::colored_output);
The example above produces the following result:
Here are some other examples:
- ascii
- matrices
- just too much…

You may want to reuse some legacy Spring beans along with CB4J or simply want to use Spring dependency injection to configure CB4J components like record mapper or processor. This does not require to write any specific integration code to use both frameworks together.
You can simply proceed as follows:
That it! Your registered beans will be configured and managed by Spring and used by CB4J to execute your batch business logic. The section below shows a use case of how to use Spring along with CB4J.
In this section, we will rewrite the Hello World tutorial to use Spring to manage the GreetingProcessor
object.
First, we will create a Spring Xml configuration file called application-context.xml
to define the GreetingProcessor
bean as follows:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="greetingProcessor" class="io.github.benas.cb4j.integration.common.GreetingProcessor"/> </beans>
Then, we will create a Spring container to manage this bean:
ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
Finally, we register as usual the GreetingProcessor
bean to be used by CB4J:
GreetingProcessor recordProcessor = (GreetingProcessor) context.getBean("greetingProcessor"); batchConfiguration.registerRecordProcessor(recordProcessor);
That's all! GreetingProcessor
bean is now managed by Spring and used by CB4J.
As you can see, no specific integration code is necessary to use Spring along with CB4J.
The complete source code of this example can be found here.
To run the tutorial with maven, launch the following command in the cb4j/cb4j-tutorials
directory :
mvn clean package exec:java -PrunSpringTutorial


Working¶
In the Usage section, we discussed about the architecture and how to use the tool. Let’s extend the discussion with a complete note of how actually the tool work.
We shall start our discussion with schema diagam of the tool.
As you can see above, there are four tables:
Query.
Query users.
Query Filters.
List commits.
Query
has the data regarding the hash
, created time
etc. All the users assosiated with the query will be stored in Query users
table. All the filters assosiated to the query will be stored in Query Filters
table.
Whenever a request of creating a server hits the server, initially a class named AddQueryUser
view is triggered. The view creates a Query with a hash and adds the users to the query. This also creates a default set of filters and rturns a redirect to /<hash>
URL.
The URL triggers DisplayResult
view. This view peforms external API requests, fetches the details and store the fetched data in the databases. It also formats the data and returns the data to the browser as a HTTP response.
Let’s dig deep to the working of DisplayResult
view.
This view uses asyncio
and aiohttp
to peform API requests in parallel manner. There are few constraints with the existing Phabricator and Gerrit APIs. Both of them can not return the count of contributions of the users. They will return the contributions made by the user in form of
list of JSON objects. The good thing about Gerit
is it returns contributions of all the users with a single API request. But in case of phabricator, it will paginate the results with a max of 100 contributions in each page Fo example, if a user performed 1000 different actions in phabricator. then
10 API requests are to be made to get all the actions the user performed. An another constraint is all the API requests are to be made in sequential manner. The API requests can not be parallel because each page has to be requested with a reference(except the first one). The reference to a page n will be provided in page n-1.
Suppose if you have to get the commits of the user in 7th page, you have to request the 6th page first to get the reference to the 7th page. To get the 6th page you have to request the 5th page and so on.
So, even if I want to get some page n you have to get all the details from 1 to n.
In this tool, all the contributions of the user from gerrit are being fetched. But in case of phabricator, two kinds of tasks are taken into count:
Tasks authored by the user.
Tasks assigned to the user.
DisplayResult view actually gets all the data required to perform the extrnal API requests and call another function getDetails
. This function takes the data and format them according to the requirement. It also creates a new asyncio event loop.
This loop is given with three different co-routines. (If you are not familiar with event loops and co-routines, they are used to perform threading programitically, you can get more information about them here).
async def get_data(urls, request_data, loop, gerrit_response, phab_response, phid):
tasks = []
async with ClientSession() as session:
tasks.append(loop.create_task((get_gerrit_data(urls[1], session, gerrit_response))))
tasks.append(loop.create_task((get_task_authors(urls[0], request_data[0], session, phab_response, phid))))
tasks.append(loop.create_task((get_task_assigner(urls[0], request_data[1], session, phab_response))))
await asyncio.gather(*tasks)
The above code adds three tasks to the event loop. Each of the task fetches APIs and get information.
get_gerrit_data()
: fetch contributions user from gerrit.get_task_authors()
: fetch tasks authored by a user in phabricator.get_task_assigner()
: fetch tasks assigned to a user in phabricator.
get_gerrit_data()
perform a single API request and gets all the details of the users.
get_task_authors()
and get_task_assigner()
gets the data but, as discussed above phabricator APIs are paginated. So, these two co-routines has to
request the data again and again, till there are no more pages left behind to request.
These are parallel because, let’s assume there are two tasks task1 and task2, initially, the loop started executing task1. If task1 peformed any API request, it has to wait till the response is received to proceed further. So, whenever the task1 performs a API request, asyncio stores the state of task1 and start executing task2. When the response to the task1 is received, it stores the current task and executes the task1 furhter.
Once the entire data are received, it is formatted and stored in the table List Commits
Along with storing them in databases, the commits that meet the requirement of all the Query filters are taken and response is returned to the user.
For the sake of performace, the contributions of at the max. of past one year are being requested.
Whenever the filters of a query are changed, if the filter “status of commit” is only changed, then there is no need to request external APIs as all the commits are avialable here. So, databases are queried and the contributions that matches to the current filters are retured. If the time stamps are changed, then the external APis are requested again and the details are fetched.
There is another view GetUserCommits
that returns all the commits of a user on the paticular date.
