Hi there! This document lives here to give you some basic information about your WordPress site and how to update it. Let's get started!
If you're somewhat familiar with WordPress, feel free to skip to the next section, it's not integral to understanding your new website. WordPress is a Content Management System (CMS) - at a basic level it performs the following functions:
At Honey Agency, we custom-build the backend so site-owners don't need to worry about code or formatting, there's a few fields that you fill out and we take care of formatting via code. We usually re-size images for you as well; so unless you see a note about image sizes when you are uploading them we're taking care of the size on the front-end.
WordPress breaks down content into pages
and posts
. A page
is the most general form of webpage content: you have some text, possibly an image, and you can access that content via a URL. A post
is similar to a page
, but it's hierarchy is based on the model of a blog: you generally have the text and image content that you'd have with a page
, but posts are displayed in series and usually have a date and an author.
These are generalizations, but are the basic grounds of how a lot of the web is built.
At Honey Agency, we try to separate content-types into custom versions of a post
to make the website hierarchy more simple and streamlined for clients. For example at honeyagency.com, we have a team page with individual team members so we have a custom post
that's called Team Member
. When you want to add a new team member you don't have to custom-format anything, you just click Add New Team Member on the backend; once you fill out all the content required the team member is automatically populated in different places on the site.
Depending on your site, you might have a few custom-posts that we'll go over in the sections below.
Logging in to your WordPress site is easy: just add /wp-login
to the end of your URL, use the Password and Username (or email) provided and you're on your way. Once you login you will see what's called the WordPress dashboard-from here you can get anywhere you need to update content. If you look at the homepage of your site while logged in, there will be a black-bar along the top of the page with links to various site functions.
One of the perks of having a site with a CMS is that you have a centralized location for any images you've added site-wide. So anytime you upload images, PDFs, audio, etc to a post, a page, or a custom post they'll be added to a folder similar to the Photos
or Pictures
folder on your computer.
To get to your Media Library, click the Media Library
navigation item in the left-hand side menu in the WordPress dashboard. You'll be presented with a gallery of all the images currently on your site.
To add a media item, click Add New
from the Media Library
. From here you can drag-and-drop however many images you like (note the Maximum upload file size, this is per-file) and they'll automatically be added and have URL's generated for them. Usually, you'll simply upload images or PDFs directly to a post or page, in which case they'll be added to this library.
In the WordPress overview, you heard that the page
is the most basic form of content in WordPress, this is how we'll add & edit those.
Once you're logged in you can add a new page from either:
+ New
and click Page
Add New
.You'll be taken to the backend of a page with no title or content, when you add a title the URL will automatically be generated for you. If you want to change that URL click the area of text you want to change and edit the text, WordPress will automatically convert your text to lower-case and will replace spaces with hyphens to be URL-compatible.
After you have your title and URL set, you can use the area below to add content. The large white text-box is called a WYSIWYG (What You See Is What You Get) and will operate similarly to Microsoft Word, Apple Pages, or Google Docs.
You'll see a bar on the right-hand side of the page with options for publishing the page. To publish (make the page go live) the page, click Publish
. If you don't want people to see the content, you can choose Save Draft
. If you want to schedule the page, you can change the date where you see Publish immediately. If you want to publish the page but only want people who are logged into the site to see it (other admins) you can choose Private
under the Visibility option.
To edit a page that is already created, you can either click Edit Page
in the black top-bar when you're looking at the page from the front-end, or you can find the page by clicking Pages
in the dashboard and clicking the blue title of the page you're looking for from the list of pages.
Adding a product starts similarly to adding pages or posts.
These fields are all pretty self-explanatory, but they display as plain-text in the right-hand aside on the product pages; leaving them blank is okay, it simply hides the title on the front-end.
This controls the way products look when they’re displayed as features on the shop page, in a few sections there’s an explanation for displaying the products.
The following feature types are available, screenshots are
General
If you’re selling a product that is technically made up of multiple SKU’s (i.e. Shirts: Large Blue, Medium Blue, Medium Yellow or Coffee: Decaf 5lb, Decaf 12oz) we need to set up variants to ensure there’s only one URL with multiple options. The benefit is that it automates the process of adding options one-at-a-time, instead you setup the variants and tell wordpress to create each SKU (for example a shirt with four sizes doesn’t need to be re-created 24 times, you simply choose each color and size and generate).
How to enable variants and set up a variable product
For this example, we’re adding a new coffee with a 5lb and 12oz variant.
Variable Product
.Add
.Save Attributes
.Go
. Accept any browser dialogs that popup.Featuring products is an action that takes place in site options instead of within products. That takes the guesswork out of sifting through product posts to see what’s featured and what isn’t.
To choose which products are featured, first navigate to your dashboard.
Shop
.All orders are organized in the dashboard under the “Woocommerce” navigation item. Hover over the nav-item and select Orders
to see a list of all orders.
Purchasing labels happens per-product and is really easy to do. Once an order is placed, the customer will receive an email to let them know that their order is in the queue to be processed. Once the order is ready to ship, navigate to the order.
Issuing refunds are simple. You can issue a full refund or a partial refund if there’s any hiccup in the ordering process or if a customer runs into issues.
Refund
Reports are a great way to get an overview of orders.
To get to reports:

Emotion and theme recognition is a popular task in music information retrieval that is relevant for music search and recommendation systems. We invite the participants to try their skills at recognizing moods and themes conveyed by the audio tracks.
This task involves the prediction of moods and themes conveyed by a music track, given the raw audio. The examples of moods and themes are: happy, dark, epic, melodic, love, film, space etc. Each track is tagged with at least one tag that serves as a ground-truth.
Participants are expected to train a model that takes raw audio as an input and outputs the predicted tags. To solve the task, participants can use any audio input representation they desire, be it traditional handcrafted audio features or spectrograms or raw audio inputs for deep learning approaches. We also provide a handcrafted feature set extracted by the Essentia audio analysis library as a reference. We allow usage of third-party datsets for model development and training, but it needs to be mentioned explicitly.
Researchers in music information retrieval, music psychology, machine learning, and music and technology enthusiasts in general.
The dataset used for this task is the autotagging-moodtheme
subset of the MTG-Jamendo dataset [1], built using audio data from Jamendo and made available under Creative Commons licenses. This subset includes 18,486 audio tracks with mood and theme annotations. In total, there are 57 tags, and tracks can possibly have more than one tag.
We also provide pre-computed statistical features from Essentia using the feature extractor for AcousticBrainz. These features are were previously used in the MediaEval genre recognition tasks in 2017 and 2018.
Participants should generate predictions for the test split and submit those to the task organizers.
The generated outputs for the test dataset will be evaluated according to the following metrics that are commonly used in the evaluation of auto-tagging systems: Macro ROC-AUC and PR-AUC on tag prediction scores. Leaderboard will be based on PR-AUC.

We're handling a big issue for some users.
We've all been enjoying the fact that our settings work accross all our Chrome browsers...until it stopped working (for some of us). Turns out Chrome sync storage is extremely limited and it's actually fairly easy to overflow it when you're using Pro4trello for many boards.
The first step was to push all settings back to Chrome local storage, which is exponentially larger. Chrome Store didn't allow Pro4trello to use unlimited storage so we'll cross that bridge if/when we get there, for now it seems there's plenty.
You can now synchronize up to 5 boards accross all your Chrome browsers.
Look for the sync icon in your bottom right corner, next to the Pro4Trello icon and click to open your sync menu.
Please have in mind that this is a temporary solution! Read below for more info :)
So glad you asked!
Since being able to sync settings accross all Chrome instances is like super relevant and a great thing Pro4Trello had since day one, we'll work to build the sync by leveraging Google Drive. The idea comes from this: in order to use sync up until this point, you had to be logged in to Chrome, which means you have a Google account, which means you have Google Drive :)
That being said, the idea is to have you authorize Pro4Trello to write all your settings into a folder in your Google Drive. Boom, problem solved!
Hint: this might actually unlock the potential for buliding sync between different users (for specific boards), so that you don't have to import and export settings to share within your team or organization.


eMail etiquette - the 60ties are calling
With WFH being en vogue these days, not only video conferencing and chat, but also eMail.
Dating back to the 1960ties, we had 6 decades to develop etiquette, which seems tobe lost to current users, so here we go again
Addressing
eMail has To
, CopyTo
(also called CC
for Carbon Copy) and BCC
(Blind Carbon Copy) as a means of addressing people. They serve distinct purposes:
- TO: This is the person (or people) we want to act on our message, do something, reply etc. A good email has only few names, ideally one. If we have an ongoing eMail thread that involves multiple actors, we most likely use the wrong channel and are better of using collaborative software like HCL Connections, HCL Sametime, Slack, Teams or Chatter
- CC: People, we think, who should be keept in the loop. We don't expect any action or reaction of them. A lot of eMail veterans automatically route those messages to a low priority place
-- BCC: all receipients here get the message and the rest of the addressies won't know. I used to call it the "mobbing copy". BCC is especially fun when someone there hits "reply all" and reveals the readership. There are few legitimate uses for this. One is distribution lists (see below), the other archive/record keeping. Our external readers don't need to know that your compliance archive has the eMail address<EMAIL_ADDRESS>If we really want someone outside the visible thread to take note - forward the message
Subject line
It is like a tweet about our content. The subject needs to justify why it is worth the time and attention to open it. So "Status", "Report" or "Important" don't cut it. Common practise we can see are qualifiers, e.g Opportunity codes or project IDs at the beginning. Something like [T3453]
- makes it easier to filter.
The biggest competitor to inbox attention by subject is the sender identity. We probably open a message one or two reporting managers up even with bad subject lines.
Content
Let's keep it crisp and short, best below 5 sentences.
We state:
- the information we want to provide
- the exact ask what action we expect, from whom and when
- name the person "team please look into... " doesn't cut it and is an indicator of a broken process
If there is a lot of information, it might better live in a Wiki, a project place or even a file share. We then provide the news cast overview and a link - Would you like to know more?
There are some interesting cultural differences. In Anglosaxon or Eastern culture we would politely address the person and add a whiff of smalltalk, something along the lines "hope that finds you well". Germans, Dutch and other Nordics consider this a waste of space and time and consider it as the ultimate courtesy to cut through the chase and get to the point.
When we address close co-workers, who value efficiency, it even is OK to skip the greeting. We need to dread carefully here, it needs to be clarified otherwise it is seen ultra rude.
Replies
Do we reply to the sender or all of the addressies together. It seems to be the default for many "replyToAll". This is especially hillarious when a distribution list sneaked on the addressies. The rationale here is: the sender wanted to keep all these in the loop, so I won't break it. For a small group, I hit replyAll, for larger ones only reply.
I would wish the eMail software would warn when you blast a reply. The guardian agrees: don't replyAll.
A special mention: cherry-picking replies. We hit reply all and remove the mailing lists - good. We just remove the project manager we compete with - bad. So we need to be careful of the ramifications. Other receipients might wonder: why are Jane and Joe no longer in this conversation?
Distribution lists
They firmly belong in BCC - avoids ReplyAll armageddon. When we use private distribution list, we need to make sure, they resolve before sending otherwise people can't reply. However - most likely - that group of people would be better served with a shared channel. A good strategy: we put it in BCC, write a two sencent summary and provide a link to the full info. Co-workers who are not into eMail will find in in their [insert the collaborative tool you use]
As usual YMMV

Klopp to rest stars for Genk visit ahead of mammoth City clash
Cape Town - Liverpool manager Jurgen Klopp is expected to rotate his squad for Tuesday night's Champions League clash with Genk at Anfield.
Joel Matip, Xherdan Shaqiri and Nathaniel Clyne all remain on the treatment table, while Ki-Jana Hoever is still away at the FIFA U17 World Cup and unavailable.
Klopp will be able to select his side from the same squad that was available against Aston Villa last weekend after everyone came through unscathed.
Even so, the Reds boss still plans to utilise his squad with one or two players set to be rested following a hectic run of fixtures, with fresh legs being brought in.
Fabinho was an unused substitute during the 2-1 win over Villa, to prevent him picking up his fifth yellow card of the season and a one-match ban, and looks set to come into the side, along with James Milner.
That means Reds skipper Jordan Henderson could be handed the chance to rest his legs ahead of this weekend's big game against Manchester City in the Premier League.
"We will hopefully have a couple of fresh legs in," Klopp said. "It's clear that we want that, but it's not like we will do so many changes that you cannot recognise our team anymore and think, 'Who is that?"
A win against Genk would go a long way to securing Liverpool's progress to the knockout stage as Liverpool have a three-point cushion over Red Bull Salzburg, who face Group E leaders Napoli.
Their 4-1 win in Belgium a fortnight ago was an occasionally chaotic affair after Klopp opted for an experimental midfield with Naby Keita and Alex Oxlade-Chamberlain, who scored twice on the night, leaving Fabinho regularly exposed.
Klopp's team selection may not be as open as that at Anfield, but he stressed the onus is always on them to attack.
For Genk, left-back Jere Uronen started when the two the sides clashed a fortnight ago but is sidelined with an injury.
Goalkeeper Danny Vukovic is also out.
Kick-off is at 22:00.

Using Memory
AI memory allows you to store some information between the BehaviorTree and the AI agent
The AI memory stores every element as object type that means that you can store on the memory almost every data type (via script).
Adding elements
C# API:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
private void Start()
{
ai.Memory.SetValue("PlayerHealth", 100.0f);
ai.Memory.SetValue("PlayerLives", 3);
}
}
Removing elements
To remove elements in the inspector it's just clicking on the (-) buttun and it will remove the selected item.
C# API:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
private void Start()
{
ai.Memory.RemoveValue("PlayerHealth");
}
}
Get values
C# API:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
private void Start()
{
float Power = ai.Memory.GetValue<float>("ShootPower");
}
}
Get values with MemoryItem:
Allows support of constant and memory-based values (memory keys) of different data types inside unity's inspector. That enables getting values without need to manually check if the value is a constant or memory value.
NOTE: it actually doesn't support array.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
using MoonBehavior.Memory;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
public MemoryItem Attack = new MemoryItem(ItemType.FLOAT);
private void Start()
{
float attack = Attack.GetValue<float>(ai.Memory);
}
}
Clear Memory
To clear the memory Simply call The Clear() Method
It will kill all the AI memory, so be careful about destroying the memory data.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
using MoonBehavior.Memory;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
private void Start()
{
ai.Memory.Clear();
}
}
Save & Load
Saving and loading data allows you to keep in HDD / RAM the AI's Memory.
It will return an byte array and you can save it later to a file and loaing it again.
Note: the serialization and des-serialization can be slow because it encrypts and decrypts the information to return safe data.
Doesn't support UnityObject-derived (UnityEngine.Object) data types because it's not safe at serialization
Saving
To save from memory call : Save()
Example saving data:
using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using MoonBehavior.BehaviorTrees;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
private void Start()
{
// Push some data to the memory
for (int i = 0; i < 100; i++)
{
ai.Memory.SetValue(i.ToString(), i + (Random.value * i));
}
// Save the memory data to ram
byte[] SavedData = ai.Memory.Save();
// save the memory to disc
File.WriteAllBytes(Application.dataPath + "/Memory.txt", SavedData);
}
}
Loading
To load from memory call : Load(byte[] Data , bool clear = false)
Data: byte array of the previusly saved data.
clear: Should clear memory before load ?
Example loading data:
using UnityEngine;
using MoonBehavior.BehaviorTrees;
public class ExampleScript : MonoBehaviour
{
public MoonAI ai;
public TextAsset txt;
private void Start()
{
ai.Memory.Load(txt.bytes);
}

VAM [1] and GSVA [2] are popular methods for GSE (Gene Set Enrichment) and allows the identification of changes in pathway activity in RNA-Seq data. Overall, gene sets can be uploaded or selected from the available databases (How to Import Genesets?), and the pathway analysis method can be run on the selected gene sets which can eventually be visualized using Violin plot.
To view detailed instructions on how to use these methods, please select “Interactive Analysis” for using pathway analysis in Shiny application or “Console Analysis” for using these methods on R console from the tabs below:
Entry of The Panel
From anywhere of the UI, the panel for pathway analysis can be accessed from the top navigation panel at the circled tab shown below.
The UI is constructed in a sidebar style, where the left-sided sidebar works for setting the parameters and running the pathway analysis, and the right part main panel is for visualization checking.
Run Pathway Analysis
1. Choose An Algorithm
For running any types of pathway analysis, there are always three essential inputs that users should be sure with:
After the pathway analysis method is confirmed, the lower part will dynamically switch to the method specific settings.
2. Parameter Settings
When the selected algorithm is “VAM” , the parameter settings will look like the figure above. The method specific parameters include:
center
, If True, values will be mean centered when computating the Mahalanobis statistic.gamma
, If True, a gamma distribution will be fit to the non-zero squared Mahalanobis distances computed from a row-permuted version of the gene expression matrix. The estimated gamma distribution will be used to compute a one-sided p-value for each cell. If False, the p-value will be computed using the standard chi-square approximation for the squared Mahalanobis distance (or non-central if center = FALSE).When the selected algorithm is “GSVA”, no additional parameter settings exist other than the three essential inputs common for both VAM and GSVA.
3. Visualization
The visualization is implemented with a plotting of cell by geneset matrix score.
The parameter panel for visualization comprises of:
The pathway analysis methods can be easily applied to a SingleCellExperiment
(SCE) object. The methods return the same SCE object with results updated in reducedDim
slot.
Basic Parameters
For each of the three functions, the common things are:
inSCE
.Import Gene Sets
tab - geneSetCollectionName
.useAssay
for a full-sized expression data.As for another essential parameter, the data matrix used for running the algorithm is a must. Here, users should notice that:
runVAM()
, there are two extra parameters: center
and gamma
. Please refer to the function manual pages for the details.Examples
To demonstrate simple and clear examples, here we use the “PBMC-3k” dataset from “10X” which can be easily imported with SCTK functions.
library(singleCellTK)
sce <- importExampleData("pbmc3k")
The preprocessing only includes necessary steps before implementing pathway analysis
sce <- scaterlogNormCounts(sce, assayName = "logcounts")
sce <- importGeneSetsFromMSigDB(inSCE = sce, categoryIDs = "H", species = "Homo sapiens", mapping = "gene_symbol", by = "rownames")
center
, If True, values will be mean centered when computating the Mahalanobis statistic.gamma
, If True, a gamma distribution will be fit to the non-zero squared Mahalanobis distances computed from a row-permuted version of the gene expression matrix. The estimated gamma distribution will be used to compute a one-sided p-value for each cell. If False, the p-value will be computed using the standard chi-square approximation for the squared Mahalanobis distance (or non-central if center = FALSE).
# Directly use an assay
sce <- runVAM(inSCE = sce, geneSetCollectionName = "H", useAssay = "logcounts", center = TRUE, gamma = FALSE)
# Directly use an assay
# not run
sce <- runGSVA(inSCE = sce, geneSetCollectionName = "H", useAssay = "logcounts")
Results and Visualization
The results generated with either GSVA or VAM are stored in the reducedDims
slot of the SCE object.
To visualize the scores for a specific geneset from the geneset collection that is used for running the algorithm:
plotPathway(sce, resultName = "VAM_H_CDF", geneset = "HALLMARK_INFLAMMATORY_RESPONSE")
In the example above, "VAM_H_CDF"
is the name of the result generated by VAM, where "HALLMARK_INFLAMMATORY_RESPONSE"
is a geneset from geneset collection "H"
, imported at the very beginning. Users can also set argument groupby
to a colData
variable for clusters or any biological conditions, in order to group the scores into multiple violin plots.
To get the names of all pathway analysis results:
## [1] "VAM_H_Distance" "VAM_H_CDF"
To get a list of all genesets that a pathway analysis result includes:
head(getGenesetNamesFromCollection(inSCE = sce, geneSetCollectionName = "H"))
## [1] "HALLMARK_ADIPOGENESIS" "HALLMARK_ALLOGRAFT_REJECTION"
## [3] "HALLMARK_ANDROGEN_RESPONSE" "HALLMARK_ANGIOGENESIS"
## [5] "HALLMARK_APICAL_JUNCTION" "HALLMARK_APICAL_SURFACE"

Compacts, processes and bundles code for inclusion in the browser. Uses browserify and babel to process source files, and makes the processed file available via a static route.
npm install nxus-clientjs --save
'client_js': {
'babel': {}, // Babel specific options. Defaults to the project .babelrc file
'routePrefix': '/assets/clientjs', // static route used to serve compiled assets
'assetFolder': '.tmp/clientjs', // local dir to write compiled scripts
'webcomponentsURL': 'js/wc-min.js', // URL to include for WC polyfill
'reincludeComponentScripts': {} // components to ignore from babel compilation but include in scripts
}
To use the module, there are two steps: 1) create the bundle, and 2) include/inject the source into your page.
app.get('clientjs').bundle('/my/local/file.js', '/browser/path/to/file.js')
You can either include the output path as specified when you creatd the bundle
<script source='/browser/path/to/file.js'></script>
Or using Nxus Templater, you can inject the script by passing the output path to the script
key on render or using the Templater
lifecycle events.
app.get('templater').render('my-template', {scripts: ['/browser/path/to/file.js']})
Or
app.get('templater').on('renderContext.my-template', () => {
return {scripts: ['/browser/path/to/file.js']}
})
You will need to install the necessary Babel presets and plugins
in your application, and add Babel configuration options to the

Mitsubishi beats Shell to purchase of Dutch energy supplier Eneco
by Edward ThicknesseDutch energy supplier Eneco this morning confirmed that it would be acquired by a Mitsubishi-led consortium for €4.1bn (£3.5bn).
The deal will give Mitsubishi 80 per cent of the company, with fellow Japanese power firm Chubu taking the remaining 20.

The group beat off bids from Shell, which joined with Dutch pension fund manager PGGM for its bid, and private equity firm KKR.
Eneco said Mitsubishi’s group had “made the best offer for shareholders and all other stakeholders of Eneco, including employees.”
The firm, which is owned by 44 Dutch municipalities, said it had been convinced by the Japanese group’s plans to let Eneco retain its corporate identity and strategy.
Eneco’s chief financial officer Guido Dubbeld told reporters that the consortium were planning to invest €1bn in Eneco’s operations across the continent in the next three years.
He said the investment would be made “mostly in the Netherlands, mostly in wind, somewhat less in solar.”
In a statement, Mitsubishi chief executive Takeheiko Kakiuchi said: “Eneco fits perfectly with our current energy activities and offers us a platform from which to grow further in the European market.”
The company already has a presence in the Dutch market with 400 megawatts of offshore wind power, which it will combine with Eneco’s operations.
The decision to overlook Shell was a setback for the oil supermajor, which has plans to become a major power generator by 2030.

The company plans to spend betweeb $2 and $3bn a year on investments in energy transitions from 2021 onwards.
In a statement, the company said it would “continue to look for opportunities in the energy transition.”


In The Mood (1987)
Grade: 73
"In the Mood" is a light comedy based on the true story of Sonny Wisecarver, a fifteen-year-old boy who made national headlines in 1944. With the Normandy invasion pending, the media was looking for some 'comic relief' and found it in Wisecarver, who had married a woman in her twenties. He was labelled the "Woo-Woo Kid", but according to Wisecarver, he was "just looking for a nice girl his age."
"In the Mood" has the outward appearance of a love story, but the film is one big wink to the audience. It isn't relevant how accurate the film is, that is, whether Wisecarver (played by Patrick Dempsey) was actually as sweet and innocent as he is portrayed. What is important is that the comedy works, that the humor is subtle rather than obvious. The troubles that Wisecarver continually gets into are delivered as comedy rather than as drama, and we are too busy laughing at him to take him seriously.
"In the Mood" did not do well at the box office, won no awards, and got middling critical reviews. But a good subtle comedy can be as rare as a snowfall in Acapulco, and "In The Mood" deserves a second look.
The real Sonny Wisecarver has a cameo as a mailman in the newsreel. He calls Wisecarver a "pervent" and a "communist". Okay, it's funny, but there really is a message: you shouldn't judge celebrities from their publicity.

Below is where you can find the latest releases of all the Selenium components. You can also find a list of previous releases, source code, and additional information for Maven users (Maven is a popular Java build tool).
The Selenium Server is needed in order to run Remote Selenium WebDriver. Selenium 3.X is no longer capable of running Selenium RC directly, rather it does it through emulation and the WebDriverBackedSelenium interface.
Download version 3.141.59
To run Selenium tests exported from the legacy IDE, use the Selenium HTML Runner.
To use the Selenium Server in a Grid configuration see the wiki page.
This is required if you want to make use of the latest and greatest features of the WebDriver InternetExplorerDriver. Please make sure that this is available on your $PATH (or %PATH% on Windows) in order for the IE Driver to work as expected.
Download version 3.14.0 for (recommended) 32 bit Windows IE or 64 bit Windows IE
CHANGELOGIn order to create scripts that interact with the Selenium Server (Selenium RC, Selenium Remote WebDriver) or create local Selenium WebDriver scripts, you need to make use of language-specific client drivers. These languages include both 1.x and 2.x style clients.
While language bindings for other languages exist, these are the core ones that are supported by the main project hosted on GitHub.
Nuget latest release is 3.4.0. Released on 2017-04-21
Selenium IDE is a Chrome and Firefox plugin which records and plays back user interactions with the browser. Use this to either create simple scripts or assist in exploratory testing.
Download latest released version for Chrome or for Firefox or view the Release Notes.
Download previous IDE versions here.
If you're using Maven, you will find more information here.
Selenium can be extended through the use of plugins. Here are a number of plugins created and maintained by third parties. For more information on how to create your own plugin or have it listed, learn more here.
You can also find a list of the Selenium source code at our GitHub repository here.
Selenium has many projects that combine to make a versatile testing system.

Overview
Cloud Optimized GeoTIFF rely on two complementary pieces of technology.
The first is the ability of GeoTIFF’s to store not just the raw pixels of the image, but to organize those pixels in particular ways. The second is HTTP GET range requests, that let clients ask for just the portions of a file that they need. Using the first organizes the GeoTIFF so the latter’s requests can easily select the parts of the file that are useful for processing.
GeoTIFF Organization
The two main organization techniques that Cloud Optimized GeoTIFF’s use are Tiling and Overviews. And the data is also compressed for more efficient passage online.
Tiling creates a number of internal ‘tiles’ inside the actual image, instead of using simple ‘stripes’ of data. With a stripe of data then the whole file needs to be read to get the key piece. With tiles much quicker access to a certain area is possible, so that just the portion of the file that needs to be read is accessed.
Overviews create downsampled versions of the same image. This means it’s ‘zoomed out’ from the original image - it has much less detail (1 pixel where the original might have 100 or 1000 pixels), but is also much smaller. Often a single GeoTIFF will have many overviews, to match different zoom levels. These add size to the overall file, but are able to be served much faster, since the renderer just has to return the values in the overview instead of figuring out how to represent 1000 different pixels as one.
These, along with compression of the data, are general best practices for enabling software to quickly access imagery. But they are even more important to enable the HTTP GET Range requests to work efficiently.
HTTP Get Range requests
HTTP Version 1.1 introduced a very cool feature called Range requests. It comes into play in GET requests, when a client is asking a server for data.
If the server advertises with an Accept-Ranges: bytes
header in its response it is telling the client that bytes of data can be requested in parts, in whatever way the client wants. This is
often called Byte Serving, and there’s a good wikipedia article explaining how it works. The client can request just the bytes that it needs from the server. On the broader web it is very useful for serving things like video, so clients don’t have to download the entire file to begin playing it.
The Range requests are an optional field, so web servers are not required to implement it. But most all the object storage options on the cloud (Amazon, Google, Microsoft, OpenStack etc) support the field on data stored on their servers. So most any data that is stored on the cloud is automatically able to serve up parts of itself, as long as clients know what to ask for.
Bringing them together
Describing the two technologies probably makes it pretty obvious how the two work together. The Tiling and Overviews in the GeoTIFF put the right structure on the files on the cloud so that the Range queries can request just the part of the file that is relevant.
Overviews come into play when the client wants to render a quick image of the whole file - it doesn’t have to download every pixel, it can just request the much smaller, already created, overview. The structure of the GeoTIFF file on an HTTP Range supporting server enables the client to easily find just the part of the whole file that is needed.
Tiles come into play when some small portion of the overall file needs to be processed or visualized. This could be part of an overview, or it could be at full resolution. But the tile organizes all the relevant bytes of an area in the same part of the file, so the Range request can just grab what it needs.
If the GeoTIFF is not ‘cloud optimized’ with overviews and tiles then doing remote operations on the data will still work. But they may download the whole file or large portions of it when only a very small part of the data is actually needed.

Today I've wondered how many homomorphisms are between the groups \((\mathbb{Z}/n\mathbb{Z},+)\) and \((\mathbb{Z}/m\mathbb{Z},+)\) with \(m, n \geq 2\). Does it make a difference if I use + or \(\cdot\) as operators?
Let \(M := (\mathbb{Z}/m\mathbb{Z},+)\) and \(N := (\mathbb{Z}/n\mathbb{Z},+)\) be groups and \(\varphi: M \rightarrow N\) be a group homomorphism. Let \(H := \{\varphi: M \rightarrow N\}\)
Some fundamental theorems (which I'm not going to prove) are:
- \(\varphi(M)\) is a group.
- \(K_\varphi := \{m \in M | \varphi(m) = e_N\}\) is a group.
- Lagrange's theorem: \(H \leq G \Rightarrow \#H | \# G\)
- \(\varphi(1)\) defines the complete homomorphism as \(\varphi(n) = \varphi(1 + (n-1)) = \varphi(1) + \varphi(n-1)\)
- \(\varphi(1) = 0\) is always a homomorphism (that maps everything to 0).
$m = n$
Theorem: \(n=m \Rightarrow |H|=n\) Proof: You can map \(1\) to \(n\) values \(\stackrel{(IV)}{\Rightarrow}\) there can't be more than \(n\) homomorphisms.
For every \(i \in \{0, \dots, n-1\}\) exists an homomorphism \(\varphi_i(1) = i\):
This means, that all of them are actually homomorphisms. For different \(i,j \in \{0, \dots, n-1\}\) the homomorphisms \(\varphi_i\) and \(\varphi_j\) are different. So we really have \(n\) homomorphisms \(\blacksquare\)
My first thought was that it's only a permutation, but
| \(m \in M\) | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| \(\varphi(m) \in N\) | 0 | 3 | 0 | 3 | 0 | 3 |
is not a permutation, but a homomorphism.
Distinct primes
Theorem: \(n, m \in \mathbb{P}, n \neq m \Rightarrow |H| = 1\) Proof:
Let \(n, m \in \mathbb{P}, n \neq m\).
Part 1: \(1 \leq |H|\)
This follows directly from (V).
Part 2: \(|H| \leq 1\)
We know that
and
Case 1: \(m > n\)
Now the kernel can't be trivial anymore, so \(\# K_\varphi = m\). This means that everything is mapped to 0. There is only one homomorphism that does so.
Case 2: \(m < n\)
Now the image \(\varphi(M)\) can't be all of \(N\). This means \(\varphi(M) = 1\) which is again the 0-mapping \(\blacksquare\)
Any $n$ and $m$
Theorem: \(|H| = gcd(n, m)\) Proof:
First a sanity check: The theorems above are special cases of this theorem. Let's try to prove it.
Let \(n\) be composed of primes \(p_1, \dots, p_x\) (where \(p_i = p_j\) is allowed). Then \(N = \mathbb{Z}/n\mathbb{Z} \cong \mathbb{Z}/p_1\mathbb{Z} \times \mathbb{Z}/p_2\mathbb{Z} \times \cdots \times \mathbb{Z}/p_x\mathbb{Z}\) according to the Chinese remainder theorem. The same is true for \(M\). As there are \(p_i\) homomorphisms between \(\mathbb{Z}/p_i\mathbb{Z}\) and \(\mathbb{Z}/p_j\mathbb{Z}\) with \(p_i = p_j\) and as you can take a \(p_i\) from the left and a \(p_j\) from the right you can combine the different homomorphisms. So it is basically a combinatoric problem. As everything (except for same primes) will only have 1 homomorphism, you have to multiply the number of homomophisms for each pair \((p_i, p_j)\). But this is simply the gcd \(\blacksquare\)
$(\mathbb{Z}/n\mathbb{Z}, \cdot)$
What changes when we use \((\mathbb{Z}/n\mathbb{Z}, \cdot)\) and \((\mathbb{Z}/m\mathbb{Z}, \cdot)\)?
Well, first of all \(m\) and \(n\) have to be primes. Otherwise, not every element would have an inverse. Second, you have to exclude 0. Which means we only use units:
\((\mathbb{Z}/n\mathbb{Z}, \cdot)^\times\) and \((\mathbb{Z}/m\mathbb{Z}, \cdot)^\times\)
According to the German Wikipedia (source):
$(\mathbb{Z}/n\mathbb{Z})^\times$ is cyclic $:\Leftrightarrow n \in \{p^r, 2p^r | p \in \mathbb{P}, r \in \mathbb{N}_{\geq 1}\}$
So there is no simple way to reduce it to the same proofs. But I've created a little script that automatically finds homomorphisms.


Starting out with a software project, authentication is usually quite a simple problem to solve. You simply create a users table in the database, collect users’ usernames and passwords (hashed and salted), and authenticate users against it. Just about every framework has a built-in way of doing authentication that can get you up and running within minutes. Usually this involves signing in the user once and storing the user’s ID in an encrypted cookie. Once the ID is stored in the cookie, all subsequent calls are authenticated using this stored user ID. This is a great way to get started but things start to break down a bit once your system contains more than one individual application, possibly under different subdomains, and you want the user to have a consistent authentication experience across the different parts of the system.
Since I often use Rails I will use examples that are geared towards Rails in this post. The same principles will apply in different programming languages and frameworks as well though.
Rails has a library called Devise that is just about the de-facto standard for authentication in Rails apps. Devise allows you to get set up quickly with a users table, password hashing, authentication strategies etc. Basically it allows you to call authenticate_user!
(if User
is the model class you are using to store user credentials) as a before_action
on any controller that you only want authenticated users to have access to. Once authenticated, you can call current_user
in the controller methods to access the currently logged-in user. This is a really nice and simple pattern and we would like to keep this pattern once we split our system up into several individual Rails apps.
Let’s say for instance we want to split the system up into 2 Rails apps, but we want to keep a single users
table between the two apps. The architecture would have to look like this:
Let’s first look at the identity provider. In order to authenticate using a JSON web token, we need to add an authentication strategy to the Devise config. In order to encode and decode JSON web tokens, we need the jwt
gem.
Add this to your Gemfile
:
gem 'jwt'
Then, let’s create a class to help us easily encode and decode JSON web tokens. Add this class, along with a matching secret, to all Rails apps (including the identity provider):
class JsonWebToken
attr_reader :algorithm, :secret
def initialize(algorithm = 'HS256', secret = "your_secret_key")
@algorithm = algorithm
@secret = secret
end
def encode(payload)
JWT.encode(payload, secret, algorithm)
end
def encode_user(user)
encode({
user_email: user.email,
csrf_token: SecureRandom.base64(32),
exp: 1.weeks.from_now.to_i
})
end
def decode(token)
return HashWithIndifferentAccess.new(JWT.decode(token, secret, true, {:algorithm => algorithm})[0])
end
end
Be sure to provide a secure secret key with which to encode and decode the JSON web tokens. The class also adds a csrf_token
claim to the JSON web token that will be used in Rails apps 1 and 2 to protect against cross-site request forgery. The expiry is set at 1 week.
Now we need to add a Devise authentication strategy that uses the JSON web token to authenticate the user. Since this is the identity provider service, we are going to expect the JSON web token to be contained in the Authorization
HTTP header. Here is what the class looks like for the Devise authentication strategy:
module Devise
module Strategies
class JsonWebToken < Base
def valid?
headers["Authorization"].present? &&
headers["Authorization"].split(" ").size == 2 &&
headers["Authorization"].split(" ").first == "Bearer"
end
def authenticate!
if claims && claims['user_email'] && (user = User.find_by_email claims['user_email'])
success!(user)
else
fail!
end
end
# It's important that this is set to false, so that the user isn't
# stored in a cookie. The user should be authenticated on each request.
def store?
false
end
protected
def claims
@claims ||= ::JsonWebToken.new.decode(token) rescue nil
end
def token
headers["Authorization"].split(" ").second
end
end
end
end
In order for the authentication strategy above to be used, the request should contain the Authorization
HTTP header with the following value: Bearer <json-web-token>
In order to add the strategy to Devise, add this to the config/initializers/devise.rb
file:
config.warden do |manager|
manager.strategies.add(:jwt, Devise::Strategies::JsonWebToken)
manager.default_strategies(scope: :user).unshift :jwt
end
This puts the JSON web token authentication strategy first in the line of strategies for the user
scope.
Now that we can authenticate against the identity provider Rails app using JSON web tokens, let’s add a controller to allow us to sign in a user using an email and password and set a valid token cookie in their browser:
class SessionsController < ApplicationController
skip_before_action :verify_authenticity_token, only: [:create]
skip_before_action :authenticate_user!
before_action :validate_params
def create
user = User.find_by_email(params[:email])
if user && user.valid_password?(params[:password])
cookies["jwt"] = JsonWebToken.new.encode_user(user)
render json: {message: "Successfully signed in", data: user.as_json(root: false), result_code: "success"}
elsif user
render json: {message: "Password incorrect", data: {password: ["Incorrect password"]}, result_code: "incorrect_password"}, status: 401
else
render json: {message: "Email incorrect", data: {email: ["Email address doesn't match any account"]}, result_code: "incorrect_email"}, status: 401
end
end
private
def validation_errors
@validation_errors ||= {}
end
def add_validation_error(key, message)
validation_errors[key] ||= []
validation_errors[key] << message
end
def validate_params
if !params[:email].present?
add_validation_error(:email, "Email address is required")
end
if params[:email].present? && !EmailValidator.validate(params[:email])
add_validation_error(:email, "Given email address is not a valid email address")
end
if !params[:password].present?
add_validation_error(:password, "Password is required")
end
if validation_errors.present?
render json: {message: "Invalid input given", data: validation_errors, result_code: "validation_failed"}, status: 400
end
end
end
You will notice that the controller contains some validation as well in case you were to want to give the user feedback in a form. This controller allows us to create a JSON web token with the identity provider. Now we need a controller to retrieve the details of the currently logged-in user from the identity provider:
class CurrentUsersController < ApplicationController
before_action :authenticate_user!
def show
render json: {message: "Success", data: current_user.as_json(root: false), result_code: "success"}
end
end
Since Devise handles the authentication for us, we can just return the current_user
in the JSON. We now have all the tools we need to start using the identity provider from the other Rails apps.
In order to maintain consistency between the Rails apps we are going to try and mimic the behavior of Devise in the other Rails apps without using Devise. First we need to create an HTTP client that will connect to the identity provider:
Add the httpclient
gem to your Gemfile
:
gem "httpclient"
Then we create the client class:
require "httpclient"
require "httpclient/../jsonclient"
class IdentityProviderClient
def get_current_user(json_web_token)
json_client.request(
'GET',
"#{base_url}/current_user",
nil,
nil,
{
"Authorization" => "Bearer #{json_web_token}"
}
)
end
protected
def base_url
"http://path.to.identity.provider.local"
end
def json_client
@json_client ||= JSONClient.new
end
end
Now we need to add methods to the ApplicationController
so that we can get the Devise-like behavior that we are looking for:
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :authenticate_user!
before_action :set_xsrf_cookie
protected
def json_web_token
cookies["jwt"]
end
def authenticate_user!
if json_web_token
current_user_response = IdentityProviderClient.new.get_current_user(json_web_token)
if current_user_response.status == 401
render json: {message: "Not authenticated", data: nil, result_code: "unauthenticated"}, status: 401
else
@current_user = OpenStruct.new(current_user_response.body["data"])
end
else
render json: {message: "Not authenticated", data: nil, result_code: "unauthenticated"}, status: 401
end
end
def set_xsrf_cookie
cookies["XSRF-TOKEN"] = form_authenticity_token
end
def jwt_claims
@jwt_claims ||= JsonWebToken.decode(json_web_token)
end
def form_authenticity_token(form_options: {})
jwt_claims[:csrf_token]
end
def current_user
@current_user
end
def valid_authenticity_token?(session, authenticity_token)
form_authenticity_token == authenticity_token
end
end
Now all controllers that derive from the ApplicationController
will be authenticated against the identity provider service. Notice that the authenticity token is read from the JSON web token in order to protect against cross-site request forgery attacks. This is obviously dependent on the browser setting the X-CSRF-TOKEN
header on AJAX POST, PUT and DELETE requests as well as setting the form_authenticity_token
param in form POSTs.
In conclusion, JSON web tokens provide an effective strategy to tackle the issue of moving the users table to a separate Rails app that acts as an identity provider in your system.
