class ActiveRecord::ConnectionAdapters::ConnectionHandler
ConnectionHandler is a collection of ConnectionPool objects. It is used for keeping separate connection pools for Active Record models that connect to different databases.
For example, suppose that you have 5 models, with the following hierarchy:
class Author < ActiveRecord::Base end class BankAccount < ActiveRecord::Base end class Book < ActiveRecord::Base establish_connection "library_db" end class ScaryBook < Book end class GoodBook < Book end
And a database.yml that looked like this:
development: database: my_application host: localhost library_db: database: library host: some.library.org
Your primary database in the development environment is “my_application” but the Book model connects to a separate database called “library_db” (this can even be a database on a different machine).
Book, ScaryBook and GoodBook will all use the same connection pool to “library_db” while Author, BankAccount, and any other models you create will use the default connection pool to “my_application”.
The various connection pools are managed by a single instance of ConnectionHandler accessible via ActiveRecord::Core.connection_handler. All Active Record models use this handler to determine the connection pool that they should use.
Public Class Methods
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 511 def initialize # These caches are keyed by klass.name, NOT klass. Keying them by klass # alone would lead to memory leaks in development mode as all previous # instances of the class would stay in memory. @owner_to_pool = ThreadSafe::Cache.new(:initial_capacity => 2) do |h,k| h[k] = ThreadSafe::Cache.new(:initial_capacity => 2) end @class_to_pool = ThreadSafe::Cache.new(:initial_capacity => 2) do |h,k| h[k] = ThreadSafe::Cache.new end end
Public Instance Methods
Returns true if there are any active connections among the connection pools that the ConnectionHandler is managing.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 544 def active_connections? connection_pool_list.any?(&:active_connection?) end
Returns any connections in use by the current thread back to the pool, and also returns connections to the pool cached by threads that are no longer alive.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 551 def clear_active_connections! connection_pool_list.each(&:release_connection) end
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 560 def clear_all_connections! connection_pool_list.each(&:disconnect!) end
Clears the cache which maps classes.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 556 def clear_reloadable_connections! connection_pool_list.each(&:clear_reloadable_connections!) end
Returns true if a connection that's accessible to this class has already been opened.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 578 def connected?(klass) conn = retrieve_connection_pool(klass) conn && conn.connected? end
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 523 def connection_pool_list owner_to_pool.values.compact end
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 527 def connection_pools ActiveSupport::Deprecation.warn(" In the next release, this will return the same as `#connection_pool_list`. (An array of pools, rather than a hash mapping specs to pools.) ".squish) Hash[connection_pool_list.map { |pool| [pool.spec, pool] }] end
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 536 def establish_connection(owner, spec) @class_to_pool.clear raise RuntimeError, "Anonymous class is not allowed." unless owner.name owner_to_pool[owner.name] = ConnectionAdapters::ConnectionPool.new(spec) end
Remove the connection for this class. This will close the active connection and the defined connection (if they exist). The result can be used as an argument for #establish_connection, for easily re-establishing the connection.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 587 def remove_connection(owner) if pool = owner_to_pool.delete(owner.name) @class_to_pool.clear pool.automatic_reconnect = false pool.disconnect! pool.spec.config end end
Retrieving the connection pool happens a lot so we cache it in @class_to_pool. This makes retrieving the connection pool O(1) once the process is warm. When a connection is established or removed, we invalidate the cache.
Ideally we would use fetch here, as class_to_pool may sometimes be nil. However, benchmarking (gist.github.com/jonleighton/3552829) showed that fetch is significantly slower than []. So in the nil case, no caching will take place, but that's ok since the nil case is not the common one that we wish to optimise for.
# File lib/active_record/connection_adapters/abstract/connection_pool.rb, line 605 def retrieve_connection_pool(klass) class_to_pool[klass.name] ||= begin until pool = pool_for(klass) klass = klass.superclass break unless klass <= Base end class_to_pool[klass.name] = pool end end

Step 1 - Initialize keystore
The keystore must be created and initialized with a key pair and self-signed cert.
Domain name:


Class reference
Auto
Use h-auto
to let the browser determine the height for the element.

h-auto

Screen height
Use h-screen
to make an element span the entire height of the viewport.

Fixed height
Use h-{number}
or h-px
to set an element to a fixed height.
h-8
h-12
h-16

Full height
Use h-full
to set an element's height to 100% of its parent, as long as the parent has a defined height.

h-full

Responsive
To control the width of an element at a specific breakpoint, add a {screen}:
prefix to any existing width utility. For example, adding the class md:w-full
to an element would apply the w-full
utility at medium screen sizes and above.
For more information about Tailwind's responsive design features, check out the Responsive Design documentation.
Customizing
Height Scale
By default, Tailwind's height scale is a combination of the default spacing scale as well as some additional values specific to heights.
You can customize the spacing scale for padding, margin, width, and height all at once in the theme.spacing
section of your tailwind.config.js
file:
To customize height separately, use the theme.height
section of your tailwind.config.js
file.
Responsive and pseudo-class variants
By default, only responsive variants are generated for height utilities.
You can control which variants are generated for the height utilities by modifying the height
property in the variants
section of your tailwind.config.js
file.
For example, this config will also generate hover and focus variants:
Disabling
If you don't plan to use the height utilities in your project, you can disable them entirely by setting the height
property to false
in the corePlugins
section of your config file:


⚠ Documentation is version-specific: This page was generated for ScottPlot 4.1.4-beta
Additional documentation and more version-specific cookbooks are on the ScottPlot Website
ScottPlot can draw some financial indicators on plots in X/Y space, but users looking to develop robust financial charts should probably look at other libraries designed specifically for financial charting. The biggest limitations are (1) lack of mouse interaction and (2) the horizontal axis is strictly numeric Cartesian space and is not ideal for plotting dates. That said, some financial charting is possible with ScottPlot, and this cookbook demonstrates common use cases.
var plt = new ScottPlot.Plot(600, 400);
// OHLCs are open, high, low, and closing prices for a time range.
OHLC[] prices = DataGen.RandomStockPrices(null, 60);
plt.AddCandlesticks(prices);
plt.SaveFig("finance_quickstart.png");
OHLC charts are an alternative to candlestick charts. They show high and low prices as a vertical line, and indicate open and close prices with little ticks to the left and to the right.
var plt = new ScottPlot.Plot(600, 400);
OHLC[] prices = DataGen.RandomStockPrices(null, 60);
plt.AddOHLCs(prices);
plt.SaveFig("finance_ohlc.png");
You probably never want to do this... but OHLCs have an X value you can customize to be a DateTime (converted to a double using DateTime.ToOATime()). The advantage is that you can use the native DateTime axis support on the horizontal axis. The disadvantage is that gaps in time appear as gaps in the candlesticks. Weekends without trading will appear as gaps. The alternative to this method is to plot a series of OHLCs using sequential numbers, then manually define the axis tick labels.
var plt = new ScottPlot.Plot(600, 400);
OHLC[] prices = DataGen.RandomStockPrices(null, 60, TimeSpan.FromDays(1));
// add the OHLCs to the plot and the horizontal axis to display DateTime tick labels
plt.AddCandlesticks(prices);
plt.XAxis.DateTimeFormat(true);
plt.SaveFig("finance_dateTimeAxis.png");
A better way to represent time on the horizontal axis is to use traditional Cartesian coordinates so each candlestick is placed at X positions (0, 1, 2, etc.), then manually define the locations and label text of important positions on the plot. This is clunky, but possible. This inelegance is why financial charting is probably best done with real financial charting libraries, not a scientific charting library like ScottPlot...
var plt = new ScottPlot.Plot(600, 400);
OHLC[] prices = DataGen.RandomStockPrices(null, 30);
plt.AddCandlesticks(prices);
// manually indicate where axis ticks should be and what their labels should say
double[] tickPositions = { 0, 6, 13, 20, 27 };
string[] tickLabels = { "Sep 23", "Sep 30", "Oct 7", "Oct 14", "Oct 21" };
plt.XTicks(tickPositions, tickLabels);
plt.SaveFig("finance_tickLabels.png");
A simple moving average (SMA) technical indicator can be calculated and drawn as a scatter plot.
var plt = new ScottPlot.Plot(600, 400);
// generate sample stock prices
OHLC[] ohlcs = DataGen.RandomStockPrices(null, 75);
double[] xs = DataGen.Consecutive(ohlcs.Length);
// calculate SMAs of different durations using helper methods
double[] sma8xs = xs.Skip(8).ToArray();
double[] sma8ys = Statistics.Finance.SMA(ohlcs, 8);
double[] sma20xs = xs.Skip(20).ToArray();
double[] sma20ys = Statistics.Finance.SMA(ohlcs, 20);
// plot technical indicators as scatter plots above the financial chart
plt.AddCandlesticks(ohlcs);
plt.AddScatter(sma8xs, sma8ys, markerSize: 0, color: Color.Blue, lineWidth: 2);
plt.AddScatter(sma20xs, sma20ys, markerSize: 0, color: Color.Navy, lineWidth: 2);
plt.SaveFig("finance_sma.png");
Bollinger bands are a common technical indicator that show the average +/- two times the standard deviation of a given time range preceeding it.
var plt = new ScottPlot.Plot(600, 400);
// generate sample stock prices
OHLC[] ohlcs = DataGen.RandomStockPrices(null, 100);
double[] xs = DataGen.Consecutive(ohlcs.Length);
// calculate the bands and the time range they cover
double[] xs2 = xs.Skip(20).ToArray();
(var sma, var bolL, var bolU) = Statistics.Finance.Bollinger(ohlcs, 20);
// plot technical indicators as scatter plots above the financial chart
plt.AddCandlesticks(ohlcs);
plt.AddScatter(xs2, sma, markerSize: 0, color: Color.Blue);
plt.AddScatter(xs2, bolL, markerSize: 0, color: Color.Blue, lineStyle: LineStyle.Dash);
plt.AddScatter(xs2, bolU, markerSize: 0, color: Color.Blue, lineStyle: LineStyle.Dash);
plt.SaveFig("finance_bollinger.png");
Newer data appears on the ride side of the chart so financial charts are often displayed with the vertical axis label on the right side as well. This is possible by disabling the left vertical axis (YAxis) and enabling the right one (YAxis2)
var plt = new ScottPlot.Plot(600, 400);
OHLC[] prices = DataGen.RandomStockPrices(null, 30, TimeSpan.FromMinutes(5));
plt.AddCandlesticks(prices);
plt.XAxis.DateTimeFormat(true);
plt.YAxis.Ticks(false);
plt.YAxis2.Ticks(true);
plt.YAxis2.Label("Price (USD)");
plt.SaveFig("finance_right.png");


Assignment: propose a final project that integrates the range of units covered:
applications_implications/index.htmlThe project I want to develop is an interactive panel. It opens and closes responding to input coming from environmental conditions, creating an artistic and functional effect.
My final project is a modular 50x50cm panel. It can be used in exhibition areas to protect works of art from sunlight. In fact, the elastic tissue that connects the three panels closes it self turning clockwise, and open up turning anticlockwise. It allows to restrict or to increase the light passing through the panel. The engine composed of toothed belts and pulleys creates this mechanism.
The project is inspired by Pierre Le Roux's works of art. Pierre le Roux is an artist based in Melbourne. He's a design specialised in metal fabrication, manufacturing and installing standout. He makes laser cut metal signs and lettering for clients all across Australia.
The total cost of a single panel will be approximately € 90, subdivided into:
Mechanical components
- 4 threaded rods
- 24 bolts
- Toothed belt 10€
- 3 plywood panels 50cmx100cm - 20€
- Stretch fabric
- 5 pulleys
- 1 Wiper Motor
- 1 Power module
Electronic components:
- Fab Kit Miky
- 2 Electronic limits 3€
- 2 Buttons 4€
- 1 Phototransistor 3,5€
USE MACHINES:
- Laser cutting
- 3d Printer
- Milling Machine
I'll realize mechanical parts with 3D printer and laser cut. Raw materials such as PLA are produced in Puglia, an Italian region. The plywood comes from a carpenter of Frosinone, pulleys are laser cut, the elastic tissue is produced by a factory in Frosinone. The power module comes from an old 5v-self phone. All electronic components come from online shop, mainly from China. The wiper motor comes from the garage of a friend of mine.
I will produce by myself all electronic shields, davits/hoist, and plywood panels. The electronic shields will be designed and milled with the SRM20. The Davits / hoist will be modeled and 3D printed, pulleys and the panels will be laser cut.
I have made a prototype, to better understand the mechanism of my project. I am waiting for some electronics components to proceed with the realization of the final model.
- What sensors to use? One of my doubts about this project was the choice of the sensors, because I had a lot of possibilities. I decided to imagine the wall I want to build into a museum, so I decided to use a light sensor, but it is possible add every sensor you need.
- Which engine to use? The hypotheses were: a servo motor, a stepper, or a wiper motor. I chose a wiper motor because it makes 360° rounds.
- It will be salable? I chose this project because I already have requests.
- 3D modeling components;
- Printing components with 3D printer;
- After that checking the correct measurements of the joints and consequently laser cutting plywood;
- When the components of electronic will come, solder and do the sketch with the Arduino IDE;
- Fit all parts and pray that it works.
- THE GOAL: One module requires different processes (electronics, programming, 3D designing and modeling, 3D printing, laser-cutting and mechanism designing). My goal for the final presentation is to have one single module assembled and working. When I began the Fab Academy 2015, my skills in electronics and programming were very poor. I guess I still have a lot to learn, but if my wall will work, it means I managed to learn how to incorporate different devices into one single mechanism. To have this module running will show my understanding of electronics programming, and how they can be applied to the fabrication of systems and mechanisms. I consider that it’s a project that puts multiple fabrication processes together in a logical way. Having it working will prove that I am on the way to be able to make (almost) anything.

Brief descriptions on what I am working on and what interests me!
I am a strong proponent of collaborative research work. Throughout my research experience (so far, much more to go!), I am extremely fortunate to have found supportive mentors and amazing collaborators. I thank them for the opportunities and advice, as none of these projects would’ve been possible without them! If you have thoughts/comments on any of the projects I am currently working on, I’d love to hop on a quick call to chat about them!
Table of Contents
What am I working on right now? ⬆
Refining LMs via human-in-the-loop explanations 🤖 ➡ 👧🏾 ➡ 🤖
In this project, our team (Aaron Chan, Ziyi Liu and Prof. Xiang Ren) aims to “close the loop” between generating and utilizing explanations. We believe that LM explanations should not just be used to passively interpret LM behavior, but rather operationalized to actively improve how LMs make decisions.
To this end, we are exploring (human-in-the-loop) HITL interventions to identifying spurious patterns in model explanations, and further utilising these intervention to regularise LMs to effectively debug them and potentially improve their performance in selected scenarios. More specifically, we are interested in the following research questions:
- How can human annotators efficiently intervene model explanations, with given time constraints?
- How can we present samples to human annotators so that we can gain maximum benefit out of them? (Like generalising to more samples, by intervening only on candidate samples)
- How can interventions provided by human annotators be utilised by LMs to regularise/tune them accordingly?
- How do these interventions help in improving model performance and fixing spurious patterns in the long run?
Implicit concept-driven model explanations 🧠 ➡ 📖
In another exploratory project, I am expounding upon current development in concept oriented model explanations (like Koh et. al, 2020). These methods extract human-readable abstractions called concepts from either model predictions or intermediate layers, which serve as key indicators of model behaviour. These concepts often serve as a proxy for model explanations, as they are used within the model for prediction, rather than post-hoc approaches.
However, for textual domains, often these concept are implicit – not present in the surface form in the text, but prior-knowledge informed. I aim to identify these implicit concepts as model explanations. More on this idea later!
Other Research Interests ⬆
Very broadly, I am interested in working on problems around developing label-efficient methods for NLP tasks (brownie points to the project if they are for developing explainable and/or robust systems). That said, I am open to exploring other ideas (hmu if you want to collaborate!)
Some stuff that I found interesting and would like to explore in the future:
-
Demystifying model explanations via human-interactions: Lately, I have been very interested in understanding the degree to which explanations align with human-perceived notions. Schuff et. al, 2022 provide interesting insights on how humans often mis-interpret saliency-based explanations and suggest approaches to mitigate it. Krishna et. al, 2022 conduct an extensive user study to formalise disagreements caused by several model explanation methods. Adebayo et. al, 2022 also explore whether model explanations are enough to identify spurious signals via user studies.
-
Utilising explanations to identify and calibrate model behaviour: I am particularly interested in using model explanations in ways that can underscore potential bias or model leakage in sensitive scenarios. I particularly like approaches like that used by Kennedy et. al, 2020, which employ explanations to identify cases where models overly rely on sensitive attributes like race, gender, etc, rather than focusing on the context surrounding them in hate speech. I am also interested in approaches that can explain moral dilemmas (for improving blackbox systems like Delphi) or identify model leakage, specifically in sensitive scenarios like clinical data, as shown by Lehman et. al, 2021.
Past Work and Side Projects ⬆
Social Networks
In what I consider past life now 😄, I spent considerable time working on topics in anomaly detection on social networks like Twitter. As a part of 2 year long undergraduate thesis work, I worked on a novel problem of collusion detection, where malicious entities come together to trade appraisals on social media platforms. Along with my team members Aditya Chetan, Dr. Hridoy Sankar Dutta and Prof. Tanmoy Chakraborty, we worked on a series of projects surrounding Collusion detection:
-
In a preliminary study (ASONAM’18), we established the differences between collusion detection and bot/spam detection methods, followed by a supervised, feature-based classification system to identify collusive retweeters over Twitter. This was an important work to actively probe collusive users and collect labelled data in that manner, along with identifying characteristics pertaining to their behaviour.
-
In a follow up work (WSDM’19), we devised an unsupervised approach in identifying collusive users, owing to the scarcity of labelled data. We made use of a learning-to-rank approach, coupled with features that were intrinsic to collusive behaviour. I am extremely proud of this work, particularly because everything from approach design to implementation was conducted by a bunch of undergrads (my collaborator Aditya and I), and provided me with the necessary motivation to pursue a PhD! 🙌🏽
-
In a spin-off project (ACM TIST) of the first work, Udit Arora and our team designed a multi-view approach to looking at collusive users – from a follower/followee, tweet and content perspective, to enrich the signals for effective classification.
Music and Machine Learning
I have also dabbled with a diverse set of problems in music (audio) and machine learning. Some problems that I have worked on:
-
What are the textual ingredients necessary to make a podcast popular? (NLP4MusA)
-
Understanding the difference between emotions conveyed and induced by hindustani classical music. (ICMI’20 Late Breaking Reports)
-
Beatbox transcription to symbolic notations: from generating a diverse dataset to a first approach in solving this task. (PAKDD’22)

ABOUT US
THE ALPS
The large European mountain range rises in the northernmost extremity of Italy, defining the geographical boundary. The imposing Alpine ridge passes through a number of regions, from Liguria to the Valle d’Aosta, Piedmont, Lombardy, Trentino Alto Adige, Veneto, and Friuli Venezia Giulia.
Territory of Peaks and Pinnacles
In all its territorial variety, Italy boasts a large number of beautiful and evocative mountain localities, ideal for visiting any time of year, whether summer or winter.What is baffling is the fact that more people don’t talk about all the majestic beauty of the mountains that surround the man-made marvel.
HUAYNA PICCHU
Sure, you know about the Seven Wonders of the Ancient World. But can you name all of the New Seven Wonders of the World? We’ll give you a hint for one: It’s in the Huayna Picchu shadows. For those who’ve visited Machu Picchu, a 15th century Incan cultural site, the fact that the Peruvian treasure was named a New Wonder is no surprise.
TABLE MOUNTAIN
One of the most unique natural structures on Earth, this aptly named South Africa attraction looks like a piece of furniture for the gods. Of course, mortals have long wanted to peek at what was sitting atop the table. So in October 1929, a system of cable cars started ushering curious visitors up.

Is there a more convenient way to unpack the components of a conclusion of the form ∃ x y, p x ∧ q y ∧ r x y
in a tactics block than using multiple cases
tactics?
you want mathlib's rcases
or core's cases_matching
oh yeah, rcases
is what I want. Much better!
@Reid Barton Also, in case you didn't know, the anonymous constructor notation ⟨..., ...⟩
is right-associative for nested constructors. So, for example, you can do rcases h with ⟨x, y, px, qy, rxy⟩
with your type. I learned this recently, and it's quite convenient.

12 workers hurt in Pasir Gudang chemical factory fire
JOHOR BAHRU: A total of 12 chemical factory workers in Jalan Nibong 1, Tanjung Langsat Industrial area near Pasir Gudang sustained burns on Sunday (Dec 8).
Seri Alam district police chief Superintendent Ismail Dollah said a fire, which happened at around 9.21am to 9.27am, was completely put out by Lotte Chemical Titan's firefighting unit.
"The incident resulted in 12 workers sustaining burn injuries on their body.
"Two of them were treated at Sultan Ismail Hospital here while four were at Pasir Gudang Penawar Hospital. Another six were given outpatient treatment at Penawar Hospital," he said in a statement.
Mr Ismail said the cause of the fire is still under investigation.

Emotional Intelligence
- What learnings did you take from the chapter?
- How much they value Emotional Intelligence & Mindfulness at Google. Google allows its engineers to spend 20% of their time working on projects outside their core jobs.
- The happiest of a person can be scientically measured by the way of gauaging the happiness in the brain. "By measuring the realative activation of a certain part
of your left prefrontal cortex versus your right prefrontal cortex. The stronger the realtive left-tilt is measure in a person, the more that person reports positive emotions, such as joy,
enthusiasm, high energy, and so on. The reverse is also true; those with higher activity on the right report negative emotions. This man is Matthieu Richard who is a bald french guy.
- Emotional Intelligence enables three important skills sets: Stellar work performance, out-standing leadership, and the ability to create the conditions for happiness
- To drive one of the black cabs in London, the driver must remember & hence be able to navigate through the 25,000 streets of London. He must also remember all the points
of interest of London. "This is a difficult test that can take two to four years of intense training to prepare for. Research has shown that the part of the brain associated with memory
and spatial navigation, the hippocampus, is bigger and more active in London cabbies than in the average person. More interestingly, the longer someone has been driving a cab in London, the
larger and more active her hippocampus"
- A simple technique for self-regulation called the "affect labeling", which simply means labeling feelings with words. For example when you feel angry if you label that emotion with
"I feel anger", it somehow helps you to manage that emotion.
- A useful reason to develop a high-resolution perception of the body is to strengthen our intuition. A lot of you intuition comes from our body. For example: University of Iowa did a scietific
experiment where they had 4 sets of cards (2 of them where red & 2 of them blue), each card in those decks either lost you some money or costs you some money, your job is to turn over the cards
one at a time to try and maximise your winnings. What you don't know at the beginning is the red cards are losing cards and the blue cards are winning cards. The question is how long will it take
for people to figure this out? What was interesting is that after 10 cards the gamblers started to generate stress responses (they hooked up each gambler to a polygrapgh - a lie detector machone - that measures the activity of the sweat glands that all
of us have below the skin in the palms of our hands). Most sweat glands respond to temperature, but those in our palms open up in response to stress - which is why we get clammy hands when we are nervous.
However what's even more interesting is that only after 50 cards did people start to develop a hunch about whta's going on. After 80 cards, most people have figured the game out & can see that the first two card decks (red)
are a bad idea.
- Put simply mindfulness is the mind of just being. All you really need to do is pay attention moment-to-moment without judging. It's that simple. Two experience a taste of mindfulness try the Easy way and the Easier way.
The Easy way is to pay attention to your breath & the easiest way is too just sit without agenda for two minutes. Too make it easier switch between the two. This simple exercise is mindfulness practice. If practiced often enough,
it deepens the inherent calmness and clarity of the mind. It opens up the possibility of fully appreciating each moment in life.
- How did you find the two minutes of mindfulness?
I used the technique given to me by chapter 1 of the book: Search inside yourself, which was Easy way and the Easier way. Switching between the two allowed me too
remain calm/present with my thoughts and often I would drift off into my own thoughts for then I would focus on my breathing again. Overall I enjoyed the two minutes
of mindfulness and I will continue to develop this important skill.

HTML, for HyperText Markup Language, is an markup language used for creating web pages.
This language is clearly oriented for designing visual objects.
It is commonly used with other languages, like CSS / JS / PHP, where each one has its specificity.
Everyone can be written in the same HTML file but it is not very confortable for coding and understanding, so each language has its own file format.
CSS, for Cascading Style Sheet, clearly defines how the webpage looks like. In this file, we can define each property for each part of the web page, as the color, the border style, the size, etc.
JavaScript, or JS, is a high level and interpreted programming language. A Javascript is run on the client, compared to PHP which is run on the server.
Basically, HTML (and CSS) is a fixed page, where nothing is moving.
So Javascript allow the webmaster to animate the page over time.
For example, it is used for user interface animations and also to modify what (and how) is written the contents of the page.
Javascript is like the "brain" of the webpage because this is in that place that each computation is done.
HTTP, for HyperText Transfer Protocol, is an application protocol through the web data (written as text) are transferred between clients and servers.
Released in october 2014, this is the version 5 of HTML programming language.
Compared to the older ones, it allow the webmaster to insert easily shades (canvas), dynamic things and multimedia objects without using plugins like Flash, Java, Windows Media or QuickTime applications.
These ones are also known for a lot of security problems, so HTML5 was a very useful evolution of HTML because multimedia objects are easy to be implemented, final user doesn't have to have extra applications on his computer to run multimedia things, and security is improved.
Dynamic HTML is like a set of technologies used to create interactive and animated websites. This is a combination of a static presentation (text and contents) with HTML, a scripting languages (as JS) and a presentation definition language (CSS). DHTML allows scripting languages to change variables in a web page's definition language. Consequently, HTML pages are not only fixed, they can be dynamic and that thing is interessant to make more user-friendly user interfaces.
To begin with HTML and JS, here is a basic application where you can create a temporary person list. User can only add items, and these ones are removed if the page is reloaded.

Add flat imagery to Mercator map databases in GEE 5.1.0
When you build a Mercator-based map database, you must build imagery projects specifically for use with Mercator-based projection (EPSG: 3857). However, with GEE 5.1.0, if you already have database imagery projects in the Plate Carrée projection (EPSG: 4326), you can re-use them for your Mercator-based map database using Mercator on the Fly. When disk space is a key consideration, you only need imagery projects in Plate Carrée projection for 2D flat, 2D Mercator, and 3D databases, reducing the storage requirements for your assets.
Mercator on the Fly converts a Plate Carrée-based imagery project into a Mercator-based imagery project when you create your map database in Fusion. When GEE Server hosts the published Mercator database, the server requests the Mercator on the Fly imagery project in the database and serves it with a Mercator projection. With some projections, you may see a reduction in serving speed when projecting a Mercator on the Fly imagery project. For more information about performance, see Mercator on the Fly Performance Data.
As you decide which type of imagery project to build, you’ll need to consider the projection types you need and whether disk space or serving speed is important. For 2D flat, 2D Mercator, and 3D databases, you can use flat imagery with Mercator on the Fly if disk space is a key consideration. However if serving speed is a key consideration, you should build both flat and Mercator imagery projects. The following table shows the decision matrix to guide you:
| Build projects/serve databases | Mercator | 2D flat and 3D | 2D flat, Mercator, and 3D |
|---|---|---|---|
| Flat imagery project | X | Disk space is most important. Flat imagery projects used for all database types, with Mercator on the Fly used to serve flat imagery for Mercator map databases. | |
| Mercator imagery project | X | ||
| Flat and Mercator imagery projects | Serving speed is most important. Flat imagery projects used for 3D and 2D flat databases; Mercator imagery projects for Mercator map databases. |
Of course, if you’re serving imagery only as Mercator map databases, you should only build Mercator imagery projects.
To add a flat imagery resource to a Mercator-based map database:
- Select Asset Manager from the Tools menu. The Asset Manager dialog appears.
- Select Mercator Map Tools (2D) from the Asset Manager toolbar. The tools for Mercator maps appear in the toolbar.
- Click . The Map Database Editor appears with no projects selected.
- Click next to Map Project. The Open Asset dialog appears.
- Navigate to the
ASSET_ROOT/Projects/Map
folder. - Select the map project that you want to add to the map database and click Open. The map project appears in the Map Database Editor next to Map Project.
- Click next to Imagery Project. The Open Asset dialog appears.
- Navigate to the
ASSET_ROOT/Projects/Imagery
folder. - Select Flat Imagery Project from the Type drop-down list, then select the imagery project to add and click Open. The imagery project appears in the Map Database Editor next to Imagery Project.
- Select File > Save.
- Navigate to the
ASSET_ROOT/Databases
folder. - In the Name field, enter a name, and click Save.
- In the Asset Manager, the new map database appears, along with the other databases you have created. Notice that the Category column distinguishes between the Google Earth databases and the Google Maps database.
- Right-click the name of your map database, and select Build from the context menu. The status of the database immediately changes to Waiting or Queued and then to In Progress.
When Google Earth Enterprise Fusion finishes building the database, its Current State column in the Asset Manager changes to Succeeded, and its Current Version column changes to the date and time the most recent build was started.
Mercator on the Fly performance data
Mercator resolution increases relative to Plate Carrée as latitude increases (or decreases) from the equator for any given map level . Therefore to obtain the correct Mercator resolution, tiles must be sampled from higher Plate Carrée levels (known as upsampling). The higher the latitude, the greater the number of tiles required and, as a result, processing time for Mercator on the Fly increases although not proportionally. The following table lists the number of Plate Carrée tiles required to produce a single Mercator on the Fly tile vs. latitude (north or south) and the approximate expected increase in processing time assuming cached tiles.
| Approximate Latitude Range(degrees) | Level Up to sample | MotF P.C. tiles processed | Max Relative Clock Time Ratio (relative to 1 tile) |
|---|---|---|---|
| 0 to 40 | 1 | 1-2 | 1 to 1.2 (2 tiles) |
| 40 to 65 | 2 | up to 4 | 2.1 (4 tiles) |
| 56 to 75 | 3 | up to 8 | 3.2 (8 tiles) |
| 75 to 85 | 4 | up to 16 | 5.1 (16 tiles) |

Today we’ll be learning about reducers, a key concept in functional programming that is at the core of Redux. First, we’ll take a step back to learn about data structures in JavaScript and study the idea of immutable state.
A reducer is a pure function that takes the previous state and an action, and returns the next state. It “reduces” those two arguments to one output:
Now you may not exactly be lining down the block just to learn about this programming construct, but trust me – reducers are pretty cool! Very helpful for managing state and keeping things organized in larger React apps.
In Javascript there are several “primitive types” (e.g.,
Number
, String
, Boolean
), each of
which stores a value of a fixed size in memory. For example, a Number type
is always exactly 8 bytes of data, to store a 64-bit floating point value.
Objects, arrays and functions, however, are more advanced data structures and they require a more sophisticated system of memory allocation and management. So an Object actually stores a “pointer” to another memory location, where the right amount of storage space can be dynamically allocated.
Object
in Javascript is known as a “reference type” because
it stores a reference to another memory location rather than storing it
directly. Since all non-primitive data structures (including Array and
Function) inherit from this same Object prototype in JavaScript, just
about every data structure we ever work with in React is stored by
reference in memory.
That may feel a bit abstract at first, so here’s an example:
// Using "=" to copy objects just duplicates the pointer, not the object itself
const josh = { name: "josh", color: "blue" };
const josh_two = josh;
josh_two.color = "red";
console.log(josh, josh_two); // both have color: red
// This invisible mutation leads to unintended side effects!
// So instead we create a new object every time, like this:
const josh = { name: "josh", color: "blue" };
const josh_two = { ...josh, color: "red" };
console.log(josh, josh_two); // different colors
In order to keep state changes and their effects throughtout the
application predictable, we follow the convention of
immutable state, creating an entirely new object with
every state change. Note how the spread operator ...
helps
streamline the syntax for this. Objects in JavaScript are mutable by
nature, so we cannot rely on a language feature like const
.
Instead, we enforce immutability as a pattern in the way we write our
code.
We’ve been following this convention all along, but it becomes especially important in larger applications with more complex and numerous state transitions. Immutable state is one of the core ideas in React, and is necessary for application-level state management with tools like Redux and Context API.
Say you’re starting a local business, like a coffee shop. Throughout the course of a day there are many different actions to be done – grinding beans, making espresso, accepting payments, and so on. Within a single transaction with a customer, there are several state changes that take place and we’d like them to take place in a specific order. Once the customer pays we’ll “dispatch” an action to update the state of their order and kick off the process of making their coffee. Here’s an example, to help us get comfortable with the language of reducers:
{order: '', cost: null, status: 'ordering'}
'PLACE_ORDER'
with payload
'oat milk macchiato'
{order: 'oat milk macchiato', cost: 3.50, status: 'ordered'}
'ACCEPT_PAYMENT'
{order: 'oat milk macchiato', cost: 3.50, status: 'paid'}
'PREPARE_COFFEE'
{order: 'oat milk macchiato', cost: 3.50, status: 'preparing'}
{order: 'oat milk macchiato', cost: 3.50, status: 'complete'}
'SERVE_COFFEE'
Even in this coffee example, you can imagine how things get complicated
quickly. 'PREPARE_COFFEE'
is a simplification of what would
actually be many separate actions like 'GRIND_BEANS'
,
'BREW_ESPRESSO'
and 'FROTH_MILK'
. For a small
menu we could easily have 20+ different actions, with a specific order of
oprations where some actions can be multitasked while other actions can
only be started once others complete.
Rather than hiring a new employee for each action, we choose to hire a skilled barista who can juggle all of these different tasks and keep things organized in an efficient process.
Likewise, in React, we don’t need to write a separate function for every possible state transition. Instead, a reducer can play the role of barista and handle all of these actions in an organized, predictable way.
So we’ve learned that a reducer basically handles several functions (now called “actions”) in an efficient way. In a React context, reducers are very helopful for state management, since we can write a single reducer that does the work of several different state management functions, all wrapped into one.
Here are the three main aspects of the pattern:
An “action” sounds like it should be a function, but in the reducer pattern an action is simply an object with this format:
const action = {
type: 'TAKE_ORDER' // action types are UPPER_CASE string constants by convention
payload: 'oat milk macchiato' // data needed to update state
}
We can start getting comfortable with the Reducer pattern and all of its
conventions by working with the useReducer
hook, an
alternative to useState
:
Here’s how it works, with a simplified version of our coffee example:
// A coffee shop with useReducer:
function reducer(state, action) {
switch (action.type) {
case "TAKE_ORDER":
return { ...state, order: action.payload, status: "ordered" };
// We'd also lookup the order cost and assign it here
case "ACCEPT_PAYMENT":
return { ...state, status: paid };
// other actions
default:
throw new Error();
}
}
// Component example with dispatch
function Menu() {
const intialState = { order: "", cost: null, status: "ordering" };
const [state, dispatch] = useReducer(reducer, initialState);
return (
<>

Central Perk Menu

<button
onClick={() => dispatch({ type: "TAKE_ORDER", payload: "macchiato" })}
>
Macchiato
</button>
<button
onClick={() => dispatch({ type: "TAKE_ORDER", payload: "espresso" })}
>
Espresso
</button>
{/* more menu items */}
</>
);
}
Redux builds on this pattern to provide a “predictable state container”, and over the next two weeks we’ll be learning about various ways of managing application-level and context-level state with Redux and Context API. Things can get confusing with the amount of abstraction involved, but as long as you’re really solid on these fundamentals you’ll be good to go!

Voice of the Mirror: Cruel hospital car park fees represent Tory broken promises
Nurses should not have to break off from their shift to feed a meter, nor patients and families with enough to deal with be burdened with extra worry about a fine
by Mirror.co.ukFive years ago the Conservatives pledged to reform hospital car parking charges. It proved yet another broken promise.
Patients, families and NHS staff are still enduring the stress and inconvenience of paying to park at a hospital.
Figures show firms operating the car parks raked in £272million last year – up from £226million in 2017. Scandalously, £86million of this came from the pockets of NHS workers.
And what’s more – some 169 trusts charge disabled blue badge holders to park.
This is a stealth tax on the sick and those who care for them.
Nurses should not have to break off from their shift to feed a meter, nor patients and families with enough to deal with be burdened with extra worry about a fine.
NHS trusts continue to hike the parking fees because they have been starved of cash by this Tory government.
If we had a properly funded health service they would not have to resort to finding other sources of revenue.
The Tories cannot be trusted to keep their word and they cannot be trusted on the NHS.
Nigel Farage is touting a nasty and dangerous right-wing agenda
The Brexit Party leader likes to present himself as the man of the people standing up against the establishment
In reality Nigel Farage is a privately educated former stockbroker touting a nasty and dangerous right-wing agenda – he’s spoken at rallies for far right parties in Europe, dismissed climate change as a “scam” and backed the privatisation of the NHS.
He is hell-bent on pushing for a no-deal Brexit that will put countless people out of work and cause economic carnage.
The fact this cut-price Donald Trump wants to form an alliance with the Tories speaks volumes about both parties.
Good sports at World up final
Whatever the result of the Rugby World Cup, England have done themselves and their country proud.
Throughout the tournament they’ve proved where there’s a ruck, there’s class.

I got an iMac. It's got a big, beautiful monitor and cool gestures. Everything works mostly. I formatted my Drobo to HFS+ awhile back and intend to plunge into the mac world full force. I want to back up my macbook pro to the Drobo, but I want the Drobo always connected to the iMac. Time machine does not officially support this.
I play around and learn that all my old macbook pro backups to the plugged-in Drobo can't be built on, since wireless backups use a sparse bundle scheme instead of a folder based filesystem. I think the sparse bundles let it backup in small (apparently 8 MB) chunks or something. It takes awhile for the shared drive to become visible to the macbook, but eventually things begin backing up after much rebooting, ejecting, and re-sharing.
Later, I close my macbook lid while it's backing up. (It feels like it's always backing up.) Then backups stop working. It says /Volumes/Drobo/vicious.sparsebundle is already in use or something.
Eventually I find this http://blog.jthon.com/?p=31, which is the most helpful post so far. I'm unable to attach with hdiutil, however, and it tells me "Resource temporarily unavailable." Thankfully a commenter on Jthon's blog suggested to simply eject the drive. OS X complained that the drive was shared and busy and I couldn't eject it, but
hdiutil eject -force /Volumes/Drobo
did the trick. After I re mounted it (
hdiutil attach /Volumes/Drobo
), I was able to hdiutil -attach the drive. However, in my case fsck_hfs -rf did not do the trick. I got
iMac:blog will$ fsck_hfs -rf /dev/disk2s2
** /dev/rdisk2s2
Executing fsck_hfs (version diskdev_cmds-540.1~34).
Invalid content in journal
** Checking Journaled HFS Plus volume.
Invalid B-tree node size
(3, 0)
** The volume could not be verified completely.
Invalid content in journal
(3, 0)
Now, however, my macbook doesn't see Drobo, and time machine thinks it needs to back up to Drobo-1. How annoying.

The core ELib package.
The class {@link E} is the core interface used by the ELib programmer.
@author Mark S. Miller


I mixed like 1/3 of an ounce of mandrake root in a blender with about 1/2 of an ounce of galangal root and an equal amount in mass of damiana and scullcap. I blended it up and wound up with a large amount of the mix. I was waiting for the water to boil when I smoked a bowl of the mixture. It had some minor effects. Nothing exciting though.
I returned and wrapped some of the mix in a coffee filter and put it in a tea ball. I had one teapot full of a light green-brownish liquid. I boiled the rest of the mix in a pot and ended up with a very dark liquid, I added lemon juice to a small amount and boiled some of the mix in another pan. I strained the liquid and had a good amount of some dark stuff. I mixed a large glass with half of the light tea and half of the dark tea. I had a few of these and began smoking a bowl of cannabis. I mixed some wormwood in because I previously had experienced a weird buzz from smoking it with cannabis. I have smoked it on its own before and gotten somewhat high off it. I read about its smokable psychoactivity in Pendell's Pharmo/kopeia. It is odd, and I have smoked fresher wormwood and the effect was stronger.
I began to get stoned, I think I packed another bowl. I got more tea and when I ran out of the light stuff I still had lots of the dark stuff left. I drank that quickly in several large glassfuls mixed with lots of sugar and downed fast. I was experiencing odd hallucinations and a weirdness to my weed high. Nothing notable but at times I was filled with energy and shook and felt things running through me. It was somewhat spiritual or magickal.
I turned off all the lights and could feel spirits. If one has seen 'Two Evil Eyes' by Romero/Argento the first tale has a scene with amazing spirit effects. I remembered this and it kind of made me feel funny, like dark and scared sort of. I think it was the Mandrake. I had some odd visuals, and relaxed for a while playing the new Game Boy. I smoked another bowl of cannabis and was all out of tea.
I then fell asleep. The next day I woke up with diarrhea and stomach pains. I attribute this to the Mandrake, based on what I've read. It lasted for an hour or so and then I smoked some cannabis and it eased it away. As have never done Galangal or Mandrake before I don't know how much of what was what. I think it was mostly Mandrake, and at first it was the Damiana and Scullcap. I was pleasantly relaxed.

Difflicious
Readable and Flexible Diffs
Jacob Wang
Scala Love 2022
“If it compiles, it works”
A career in goat farming looks great all of a sudden…
Differ
s (derive + configure)
Differ[List[Int]]
) to “summon” an instance
Differ
s to diff values
import difflicious.Differ
import difflicious.implicits.*
import difflicious.munit.MUnitDiff.*
case class Foo(i: Int, s: String)
// Create the differ
given differ: Differ[Foo] = Differ.derived
val expected = Foo(1, "a")
val actual = Foo(1, "b")
// Assert no difference between two values
differ.assertNoDiff(actual, expected)
Foo( i: 1, s: "b" -> "a" )
==
Vector( Map( "Bono" -> Set( "Plant", "Plates" ), "Sven" -> Set( "Plates", ) ), )
From the diff we see that:
List( Cat( name: "Bono" -> "Lucy", age: 7 -> 14, ), Cat( name: "Sven" -> "Bono", age: 3 -> 8, ), )
pairBy
to get more meaningful diffs!Let’s ignore dog IDs from comparison
given Differ[Dog] = Differ.derived
val expectedDogs = List(Dog(0, "Wolfy"), Dog(0, "Bamboo"))
val dogData = List(DogData("Wolfy"), DogData("Bamboa"))
val actualDogs = registerDogs(dogData)
List( Dog( id: [IGNORED], name: "Wolfy", ), Dog( id: [IGNORED], name: "Bamboa" -> "Bamboo", ), )
.ignoreAt(_.each.id)
_.each.id
is the “path expression”There are other useful configuration methods like .configure
and .replace
given Differ[Employee] = Differ.derived
given Differ[DogZoo] = Differ.derived
val newDogsDiffer: Differ[List[Dog]] = // a heavily configured Differ[List[Dog]]
val configuredDogZooDiffer = Differ[DogZoo]
// .configure allows you to "focus" on a differ inside to make multiple tweaks to it
.configure(_.employees)(_.ignoreAt(_.each.age).ignoreAt(_.each.hoursWorked).pairBy(_.name))
// .replace will replace the Differ at the given path
.replace(_.dogs)(newDogsDiffer)
| Differ Type | Allowed Paths | Explanation |
|---|---|---|
| Seq | .each | Traverse down to the Differ used to compare the elements |
| Set | .each | Traverse down to the Differ used to compare the elements |
| Map | .each | Traverse down to the Differ used to compare the values of the Map |
| Case Class | (any case class field) | Traverse down to the Differ of the field |
| Sealed Trait / Enum | .subType[SomeSubType] | Traverse down to the Differ for the specified sub type |
Let’s track office capacity and that everyone is dressed correctly :)
sealed trait Person:
def name: String
object Person:
case class Contractor(name: String) extends Person
case class Employee(name: String, attire: String) extends Person
case class OfficeCapacity(
home: Set[Person],
office: Map[Int, Person]
)
// Derive default differs
given Differ[Person] = Differ.derived
given Differ[OfficeCapacity] = Differ.derived
val officeCapacityDiffer = Differ[OfficeCapacity]
// Pants optional when WFH ;)
.ignoreAt(_.home.each.subType[Employee].attire)
// Pair people by name when comparing
.configure(_.home)(_.pairBy(_.name))
What a diff output might look like:
OfficeCapacity( home: Set( Employee( name: "Sarah", attire: [IGNORED], ), Contractor != Employee === Obtained === Contractor( name: "Paolo", ) === Expected === Employee( name: "Paolo", attire: [IGNORED], ), ), office: Map( 1 -> Employee( name: "Percy", attire: "casual" -> "suit", ), ), )
Differ.useEquals
if just want to compare a type by ==

getName
java.lang.String getName()
Returns the name of the link- Returns:
- the link name
-
delivery
Delivery delivery(byte[] tag)
Create a delivery object based on the specified tag and adds it to the this link's delivery list and its connection work list. TODO to clarify - this adds the delivery to the connection list. It is not yet clear why this is done or if it is useful for the application to be able to discover newly created deliveries from theConnection.getWorkHead()
.- Parameters:
tag
- a tag for the delivery- Returns:
- a new Delivery object
-
delivery
Delivery delivery(byte[] tag, int offset, int length)
Create a delivery object based on the specified tag. This form of the method is intended to allow the tag to be formed from a subsequence of the byte array passed in. This might allow more optimisation options in future but at present is not implemented.- Parameters:
tag
- a tag for the deliveryoffset
- (currently ignored and must be 0)length
- (currently ignored and must be the length of thetag
array- Returns:
- a Delivery object
-
head
Delivery head()
Returns the head delivery on the link.
-
current
Delivery current()
Returns the current delivery
-
advance
boolean advance()
Attempts to advance the current delivery. Advances it to the next delivery if one exists, else null. The behaviour of this method is different for senders and receivers.- Returns:
- true if it can advance, false if it cannot TODO document the meaning of the return value more fully. Currently Senderimpl only returns false if there is no current delivery
-
getSource
Source getSource()
-
getTarget
Target getTarget()
-
setSource
void setSource(Source address)
Sets the source for this link. The initiator of the link must always provide a Source. An application responding to the creation of the link should perform an application specific lookup on thegetRemoteSource()
to determine an actual Source. If it failed to determine an actual source, it should set null, and then go on toEndpoint.close()
the link.- See Also:
- "AMQP Spec 1.0 section 2.6.3"
-
setTarget
void setTarget(Target address)
Expected to be used in a similar manner tosetSource(Source)

-
next
Link next(java.util.EnumSet<EndpointState> local, java.util.EnumSet<EndpointState> remote)
-
getCredit
int getCredit()
Gets the credit balance for a link. Note that a sending link may still be used to send deliveries even if link credit is/reaches zero, however those deliveries will end up beingqueued
by the link until enough credit is obtained from the receiver to send them over the wire. In this case the balance reported will go negative.- Returns:
- the credit balance for the link
-
getQueued
int getQueued()
Gets the number of queued messages for a link. Links may queue deliveries for a number of reasons, for example there may be insufficientcredit
to send them to the receiver, they may not have yet had a chance to be written to the wire, or the receiving application has simply not yet processed them.- Returns:
- the queued message count for the link
-
getUnsettled
int getUnsettled()
-
getSession
Session getSession()
-
getSenderSettleMode
SenderSettleMode getSenderSettleMode()
-
setSenderSettleMode
void setSenderSettleMode(SenderSettleMode senderSettleMode)
Sets the sender settle mode. Should only be called during link set-up, i.e. before callingEndpoint.open()
. If this endpoint is the initiator of the link, this method can be used to set a value other than the default. If this endpoint is not the initiator, this method should be used to set a local value. According to the AMQP spec, the application may choose to accept the sender's suggestion (accessed by callinggetRemoteSenderSettleMode()
) or choose another value. The value has no effect on Proton, but may be useful to the application at a later point. In order to be AMQP compliant the application is responsible for honouring the settlement mode. SeeLink

Initially, I was hoping to explore and make light of a less discussed stereotype. But after spending only an hour at my current position yesterday, it became clear that I needed to voice my experiences with sexism and its slow-acting eventual negative implications on individuals’ mindset as well as performance. I am, and have been the only female in my company for the past year and a half. This didn’t faze me since I was raised by my father and brother and have generally always been around a majority of males (most of my friends are males and I lived in a house of all males all through college). This was just another coincidence. In the past several months however, I have been increasingly more aware of the very obvious divide not only in treatment but also in realization, or lack thereof, that one even exists between males and females.
If I’m being completely honest here, my own awareness has only been recent, shamefully. But what’s most alarming is that I have been living a life where it was just the norm. Perhaps my lack of realization stems from being raised around males. I was usually always warned away from things out of love because they were “concerned” but I definitely feel that it resulted in my acceptance of what was and not push to try harder when I was younger. I am not saying that my family was/is trying to prevent me from succeeding but I don’t think that they fully realize the way they treat me can make me feel inferior. Luckily, I’m very headstrong (some say stubborn) so I found myself ignoring most of that and choosing to be independent at a very early age
Recently, several companies including Verizon, Always, and Pantene have been engaging in campaigns to raise awareness of distorted perceptions of what it is “to be a girl” and how can actually mold individuals.
In the workplace, I think I subconsciously took note of certain remarks but just shrugged them off. What prompted me to decide to write about sexism is not that it has increased dramatically or anything like that. It was simply my newfound awareness that this was and has been happening. The most recent encounter is a great example of how sexism is mixed into so-called praise by a person who had no intention to explicitly talk down to me. When I presented work on a project to my manager, they responded with “good girl”. That statement initially made me feel like I had to be grateful of praise rather than deserving of it. I’m positive if I were male, they wouldn’t have responded with “good boy”. And this is just one example. Little things like that can be shrugged off, but why?? I truly believe that the more an individual is faced with situations that chip away at an eroding self-perception, the more they will believe that that is what they are worth.
Dealing with stereotype threat is always difficult to do especially since we believe that social reforms have changed (id urge you to click on the title of this blog) and that raising an issue of sexism is, in and of itself taboo. Although I did not raise any attention to my most recent experience at work (or any previous ones), I plan to act on and stop any form of sexist remarks- intentional or not. I plan on providing meaningful feedback by asking that individual if they would have talked that way to another male. If not why? If so, touché. I can already tell that I will be surrounded by considerate individuals at DBC, so if I were to mention that I felt as if I was being talked down to or stereotyped for being a female, I think the feedback would be welcomed. At least I hope so. I have also been made out to feel like I was making a fuss out of what seemed to be nothing in the past.
I know that Dev Bootcamp is pretty big on women’s activism in software. They hold engineering empathy sessions that discuss how a dominating male presence can make women feel alienated or uncomfortable. Hopefully they also provide tools in order to address the topic without anyone being offended.

Beverly is a small custom furniture manufacturer in Pomona, California. At Beverly, I got to do many projects; from creating the social media posts and newsletters, to redesiging the website and logo and being the assistant editor of the Room Service Catalog.
I joined Beverly as a designer after a change in CEO, and under a newly hired Marketing Director. The idea was to redesign the entire business with the creation of a new product catalog, Room Service, a website redesign (and an e-commerce site), and an app store app.
Our goal was to modernize the company and attract new customers as the company entered new territory by attending Trade Shows such as High Point Market.
Beverly’s clients were interior designers and online retailers. While Beverly specialized in custom high-end furniture, sometimes they did individual client work such as restorations--this was not the audience we wanted to focus engagement with. Because the main goal was to attract more interior designers, our persona became Kim (the CEO's wife), or rather, a fictionalized and generalized version of Kim, because she was an interior designer.
Beverly’s first logo was created by the son of the CEO, after many years, it was changed by the marketing director who hired me (second image). The marketing director wasn’t content with the current design and wanted to lighten the color scheme so that the website could also match the light theme. He wanted to keep the ‘b’ but he asked me to make it more “light.”
When we began working on the website I was told to not alter the front page **except for the background** because the CEO had paid someone to design it with the dark color scheme. (later this changed)
Our team consisted of me, a developer, and the Marketing Director. He created a lot of the tasks I was to complete, and gave me guidance in their design and implementation. For a short period of time, we had another graphic designer join when the task of redesigning the website and expanding the online shop became too much for both of us alone.
One of the biggest problems we faced at Beverly was the sense of uncertainty. The company had been under a lot of financial hardship and the redesign was it’s last effort at reestablishing itself. New management and old management often collided in what they believed the future was which left us with a lot of misdirection. Our biggest deadlines were always trade shows because that was when they had the best sales. For the entirety of 2015 a new project was completed before every trade show Beverly attended.
My time at Beverly was a success because we brought the company to new peaks. At the third trade show the company presented at in 2015, we ended up selling all the pieces before the show even began. The company grew an online following, and the online shop brought in many new clients.
Of course there are things I would change and would have preferred to do differently. I didn’t have the creative freedom I would have liked, but that’s part of designing for a pre-existing brand as opposed to creating your own. I had to learn to build on top of what previous employees had created before me.
The biggest issue we had during my time there was with the website, it had been designed by someone else, so when my deadline was set the company didn’t have the credentials to edit the code, which ended up giving us a very limited time to make the changes we ended up needing.
