After months of writing and rewriting, I am happy to finally announce RNCryptor 4 beta 1 in Swift.
RNCryptor 4 is a complete rewrite of RNCryptor for Swift 2 with full bridging support to Objective-C. It has a streamlined API, simpler installation, and improved internals. It continues to use the v3 data format and is fully interoperable with other RNCryptor implementations.
For users desiring a fully Objective-C solution, v3 is still available. I don’t currently plan to do significant new work on v3, but will consider it if there is strong interest. Going forward, I expect most OS X and iOS projects to be able to accept a mix of ObjC and Swift code. Objective-C continues to be a fully supported language in RNCryptor 4.
I plan to convert this to a final release in a week or so if no major issues are discovered.
I now move onto:
- Continuing to prepare for dotSwift.
- Getting back to the blog.
- RNCryptor v5, which will finally update the data format to improve performance, security, and robustness. Much of the v4 design was specifically to make v5 easier to write.


Extending the Schema (advanced)
Internally, we use an augmented schema with some additional proprietary columns and measurement tables.
This section examines our process for developing an extensible schema mechanism, and describes how the core schema can be augmented to fit custom requirements. Note that this process is quite involved, and we recommend using tags for most use cases instead of a customized schema.
Thanks to Leslie Lam for all her work on making persistence generic, and for writing the original form of this document.
How to Extend the Schema
An augmented schema will need to have a custom version of CorePersistenceUtils
.
This requires several major changes to the persistence
, arbiters
, and collectors
packages.
- Generate Slick tables to represent your new custom Warp Schema.
- Extend
CoreQueries
, andCorePersistenceUtils
. - Create
Core
andInternal
implementations ofAbstractQueries
andAbstractPersistenceUtils
- Define
Core
andInternal
implementations of each of the Arbiters - Define
Core
andInternal
implementations of each of the Collectors
In general, the Core classes/traits inherit from the Abstract traits, and augmented Internal classes/traits inherit from Core. This linear inheritance model helps decrease code duplication, as the Internal classes will only need to override methods that use custom augmented internal-only columns/tables.
Slick
We use Slick to generate classes that allow us to interact with the database using nice Scala collection-like functions. However, there are several caveats that make generic persistence difficult. (Spoiler: we solved all our problems using type classes).
Problem 1: Case to Case Inheritance
Slick generates case classes that represent a row in a table. e.g. case class BuildRow(...)
. If we wish to
override the return type of methods defined in AbstractQueries
with more specific types, we need these case classes
to inherit from each other.
However, case-to-case inheritance is prohibited in Scala.
In order to circumvent this, we create wrapper classes for all of the core case classes. We then define
implicit conversions between the case classes and the wrappers, thus allowing us to use them interchangeably and still
adhere to our linear inheritance model. The wrapper classes are then extended to create their custom augmented forms.
|
|
Fortunately, all of this can be generated automatically by extending Slick’s source code generator.
Problem 2: Slick Queries are Invariant
|
|
The first type parameter +E
(which is covariant) corresponds to the autogenerated Table class (which extends profile.api.Table[U]
). The
second type parameter U
corresponds to the autogenerated case class representing the Row.
The third type parameter C[_]
is the container type
for the query results (usually Seq
). Unfortunately, because U
is declared as invariant, Query[A, B', C]
is not
considered a subclass of Query[A, B, C]
, even if B'
is a subclass of B
. This is problematic because several of
methods are defined with return types of Query
. If we use these return types in the abstract definitions, then we
cannot override them with more specific types in the Core/Internal implementations.
Our workaround is using DBIO
instead of Query
when we need covariance. This means that we
must use for-comprehensions when dealing with the results, instead of directly using collection-like methods.
The Database Inheritance Model
While subclassing and inheritance does not really apply to databases… we’re going to do it anyway. The Internal database can be considered a “subclass” of the Core database, as it completely encompasses the Core database, adding columns and tables as necessary.
There are essentially three “layers” to our model that occur everywhere: an abstract layer, a Core implementation layer, and an augmented Internal implementation layer, with each layer inheriting from the one above.
Our database model is as follows:
-
com.workday.warp.persistence.model.TablesLike.scala
:A trait
TablesLike
containing all of the supertraits describing the required tables in the Core Schema. e.g.1 2 3 4 5 6 7 8
trait BuildRowLike { val idBuild: Int val year: Int val week: Int val buildNumber: Int val firstTested: java.sql.Timestamp val lastTested: java.sql.Timestamp }
This trait will also contain the type class definitions for each
RowLike
(See: Type Classes) -
com.workday.warp.persistence.model.Tables.scala
:This file contains Slick’s autogenerated representation of the Core schema. It also contains the implicit objects defining the type class for each Row.
-
com.workday.warp.persistence.model.internal.Tables.scala
:This file contains Slick’s autogenerated representation of the Internal schema. It will look the same as the Core
Tables.scala
except that the case classes defined in this file will inherit from their correspondingWrapper
classes defined in the CoreTables.scala
, which allows linear inheritance. e.g.Notice how all of the overlapping columns have an1 2 3 4 5 6 7
case class BuildRow(override val idBuild: Int, override val year: Int, override val week: Int, override val buildNumber: Int, confidenceLevel: String, override val firstTested: java.sql.Timestamp, override val lastTested: java.sql.Timestamp) extends BuildRowWrapper(idBuild,year,week,buildNumber,firstTested,lastTested)
override
operator, while the new columnconfidenceLevel
does not. There is one important limitation: the columns must be defined in the same order as the original columns, otherwise the parameter list in theextends
clause will be incorrect. You can insert new columns, but you may not reorder the existing ones.
The database model is defined as a trait, so it cannot be used directly. Instead, we have defined a separate Tables
object in com.workday.warp.persistence.(internal).Tables.scala
which mixes in the correct model.Tables.scala
trait, defines the correct Slick JdbcProfile
, and provides other convenience functions. In order to access these classes,
please import this object.
A corresponding TablesLike
object has also been created in com.workday.warp.persistence.TablesLike.scala
which
allows importing of the TablesLike
traits.
The reason for creating accessor objects is because if the types are mixed in, then Scala will infer path-dependent types, resulting in type mismatch errors.
Queries, PersistenceUtils, and PersistenceAware
AbstractQueries.scala
This file defines all of the queries that Warp Core supports. These queries ideally should not be called directly
through client code, but rather through the corresponding PersistenceUtils
. In addition, you’ll notice that all of
the return types are defined in terms of TablesLike
.
PersistenceAware.scala
This is a trait that can be mixed in to enforce the definition of some PersistenceUtils
. It defines a
protected trait AbstractPersistenceUtils
which defines utility functions for interacting with the database. Notice
that initUtils()
is called in the body. initUtils()
is defined as an abstract function which should be overridden
to initialize the database (create the schema, insert seed data, etc.). This ensures that the queries will not throw
exceptions.
Generally, we define a companion object which contains the initialization logic in its body. Because
companion objects are lazily initialized, we override initUtils()
by calling something defined in the object.
AbstractPersistenceUtils
and its subclasses are protected traits in order to prevent clients from
creating a PersistenceUtils
without initializing the correct schema first. As a result, PersistenceUtils
can now
only be accessed by classes or traits that mix in some form of PersistenceAware
.
Originally this was achieved by initializing the schema when PersistenceUtils
was initialized, but because
InternalPersistenceUtils
inherits from CorePersistenceUtils
, this caused initSchema()
to be called multiple
times, resulting in the Core schema being loaded instead of the Internal schema. With the overridden initUtils()
function, we ensure that the correct initSchema()
is called and only called once.
CorePersistenceAware.scala and InternalPersistenceAware.scala
These files implement the Core and Internal versions of PersistenceUtils
, respectively. InternalPersistenceAware
is
not part of our open-source package. Note that
InternalPersistenceAware
extends CorePersistenceAware
, allowing InternalPersistenceUtils
to subclass
CorePersistenceUtils
. This is important because it allows us to easily create internal versions of classes (i.e. arbiters,
collectors) by simply extending the core version and additionally mixing in InternalPersistenceAware
.
Initializing the Schema with Flyway Migrations
The initSchema()
function defined in the PersistenceUtils
companion objects use
flyway for database migrations.
Internally, we use a completely different set of migrations.
Any schema migrator can mix in the trait MigrateSchemaLike
and call the migrate
method:
|
|
The migration to create the Core schema lives in the default flyway directory db/migration/
.
A Failed Attempt at Generifying Persistence: Structural Types
Structural Types, or “Duck Typing”, defines a type based on its interface. This allows you to pass in objects to a function as long as it satisfies the defined structure.
|
|
This defines a TestExecutionRowLikeType
to be any object that contains the corresponding values. Therefore, all of our
classes and case classes satisfy this structural type. After defining all of these types, we can define our functions as
follows:
|
|
Satisfyingly clean! We then define augmented Internal versions of the structural types in order to match on the type parameter in the internal implementations.
|
|
Everything compiles and tests pass! Except for one insidious compiler warning:
a pattern match on a refinement type is unchecked
case r: InternalTestExecutionRowLikeType => r
Defeated by type erasure! The issue here is that structural types are erased at runtime, so the match statement actually becomes something like:
|
|
which will always succeed. Of course, this is not ideal; the code only works if the user passes in the correct
TestExecutionRow
type.
Winning the War: Type Classes
Our final (and successful!) attempt was type classes. To quote the official Scala team blog:
Type classes are a powerful and flexible concept that adds ad-hoc polymorphism to Scala.
Our solution uses type classes to achieve the same behavior has structural typing, but it also allows us to match on the parameter type. (With the added benefit of avoiding the overhead of reflection!)
Type classes allow us to define a contract which objects must satisfy. In our case it’s the same as the structural type.
|
|
You’ll notice that the type class TestExecutionRowLikeType
takes some generic T
which must define functions that return the column values.
We then simply need to define these functions in an implicit object. This provides implicit evidence that TestExecutionRow
is
TestExecutionRowLikeType
. As a result, when given some object of TestExecutionRowLikeType
, we can use implicitly
to
access the relevant columns. Of course, this is rather unwieldy, so we provide another implicit conversion that
converts from the type class to the case class. Keep in mind that all this boilerplate is generated using the Slick code generator.
It’s important to note that the context bounds are actually syntactic sugar for implicit parameters:
|
|
TestExecutionRowLikeType[T]
.
Consequently, this means that our implicit objects (e.g. TestExecutionRowTypeClassObject
) need to be in scope. In
general, these will be in scope as long as you import Tables.RowTypeClasses._
or TablesLike.RowTypeClasses._
.
We’ve included a helpful ImplicitNotFound
message that will be printed at compile time if Scala cannot find the
correct implicit, such as:
Could not find an implicit value for evidence of type class TestExecutionRowLikeType[TestExecutionRow].
You might pass an (implicit ev: TestExecutionRowLikeType[TestExecutionRow]) parameter to your method or import Tables.RowTypeClasses._
The best part is that all of these type classes and implicit objects can be generated automatically with Slick’s
source code generator! Hurrah! We may have lost many battles, but we have won the war! In addition, we never have
to lie to the compiler with asInstanceOf
, which is keeping with our Workday core value of integrity :)
To truly understand what’s happening with type classes, I highly recommend reading this series of blog posts by Aakash N S:
An Aside about Identifiers
Several of our queries look up rows based on some set of primary keys. In our augmented internal schema, this is usually the
methodSignature
and the confidenceLevel
or the idTestDefinition
and the confidenceLevel
. In our open-source package, however,
there is no confidenceLevel
, and rows are identified by either the methodSignature
or the confidenceLevel
. In
order to define a common abstract function that these queries can implement, we need to combine these parameters and
create functions that read from an Identifier
(similar to a composite key).
We also achieved this with type classes.
|
|
We then define a CoreIdentifier
which implements this type class and an InternalIdentifier
which includes the
additional confidenceLevel
field. The handling of the Identifiers
is similar to how we handle the different Row
type classes, where the augmented internal implementations match on the IdentifierType
.
Summary
If you have a unique use case, it is possible to use WARP with a customized schema, however a simpler approach is using tags for recording additional metadata.
- Traits and type classes are autogenerated into
model.TablesLike.scala
- Table classes, case classes, and implicit type class objects are autogenerated into
model.Tables.scala
- Use the
TablesLike
andTables
objects defined incom.workday.warp.persistence
to access the generated traits - Mix in some form of
PersistenceAware
and use the providedthis.persistenceUtils
in order to access the persistence functions - Make sure you import the correct
Tables._
. Also don’t forgetTables.RowClassTypes._
to bring the implicit objects in scope
This tweet by Aakash N S essentially summarizes the main lesson learned from this endeavor:
As a rule of thumb, the answer to every question of the form “Can I do XYZ in #Scala?” is “Yeah, totally man! Just use implicits.”


The Kano-Konnect project runs in production on an EC2 micro instance in the eu-west-1 Availability zone. At present, the EC2 instance is named “kano-konnect-webserver”.
The EC2 instance is part of a security group that exposes port 80 to the open internet. The deployment uses nginx as a reverse proxy to listen on port 80 and route requests from the open internet into a uWSGI webserver. The nginx reverse proxy also directly serves static files (images, CSS, etc.) out of a directory inside the main project repo.
A uWSGI server runs the Django project code. We also run Celery workers to process asynchronous tasks (with tasks and results passed back and forth via a RabbitMQ server.)
<IN THE FUTURE> Finally, an instance of JenkinsCI is running on the server. Jenkins listens to a Github webhook, and when a new build is pushed to the master repo, Jenkin runs the project test suite. If the test suite passes, Jenkins deploys the new commit to the live production server. </FUTURE>
All project/Python code lives in the directory:
/srv/kano_konnect
This directory contains three subdirectories:
releases – where the actual Python code lives. The live code is currently inside releases/kano_konnect. But more directories can be created here to allow testing of new major releases while still enabling rapid rollback. In the future, directories will be named a corresponding git commit hash.
shared – where any files that will be common to all releases should live. Currently, that mainly means the project virtualenv which is located at /srv/kano_konnect/shared/env
current – a symlink to the current, production code.
Static files are served directly off the server from a file system directory via nginx (see below.)
For ease of use, I track all the statics in Github and simply push/pull them to the server. So the static directory is inside the project repo (currently at /srv/kano_konnect/current/kano_konnect/assets/).
This may not be best practice overall (git is not ideal for non-text files like images) but in my experience it works fine up to at least ~100mb of static assets. And it makes the deployment process much simpler. Just make sure to run:
python manage.py collectstatic
git add <[asset directory]>
Before pushing commits to Github.
Updating the production virtualenv is not yet automated. So if you add new packages to the project, you must install them manually. To do this, first make sure that the requirements file is updated (e.g. if you add a package via pip, make sure to add the corresponding package with version number to the requirements file.)
Then run::
source /srv/kano_konnect/shared/env/bin/activate
pip install -r requirements.txt
The nginx server is configured by two key config files.
The actual nginx server config is at:
/etc/nginx/nginx.conf
And the kano-konnect site specific configuration is at:
/etc/nginx/sites-available/kano_konnect.conf
(The site specific file is symlinked to /etc/nginx/sites-enabled/kano_konnect.conf to make nginx actually serve the site.)
location /static/ must point to the directory where static files live on the server (currently the “assets” directory).
Before pushing a commit to Github, you should collect static files (which will put everything into the assets directory.) Then when you pull on the server, the static assets will be pulled from Github and put in the right place.
location / must point to the socket or port that uUWGI is listening on.
Currently I have uWSGI running on port 9090. It may be somewhat faster to run on a unix socket but for a low traffic site the difference is likely to be immaterial. I’ll leave it as it is for now because it currently works fine.
This can easily be changed if you have a preferred way to run uWSGI.
The project repo is owned by the “nobody user” so nginx must run as “nobody”. This is accomplished by adding the line:
user nobody nogroup;
to nginx.conf
The uWSGI process (and also Celery – see below) is managed by supervisor, a python process controller that gives a convenient way to keep the server process alive by restarting it if it crashes for some reason.
Supervisor also gives a way to start/restart the uWSGI process from the commandline via the supervisorctl command, e.g.:
sudo supervisorctl restart kano_konnect-uwsgi
Supervisor needs to be told how to start the uWSGI and celery processes, and those instructions live at:
/etc/supervisor.d/kano_konnect-uwsgi.conf
and:
/etc/supervisor.d/kano_konnect-celeryd.conf
The key line in these files is:
command=/srv/kano_konnect/shared/env/bin/uwsgi --http :9090 --wsgi-file kano_konnect/kano_konnect/wsgi.py
This line must specify exactly how the process would be started from the commandline. If you wish to change uWSGI to use a Unix socket (or an .ini file), you’ll need to edit this line.
By default, supervisor routes all log output to the directory:
/var/log/supervisor/
And creates one log file for the stdout and stderr of each managed process.
If you edit supervisor config files, you must “reread” them with the command::
sudo supervisorctl reread
And then reload supervisor with::
sudo supervisorctl reload
You can also restart supervised processes with:
sudo supervisorctl restart [PROCESS_NAME]
The uWSGI configuration is currently very “off the shelf”. No .ini file is being used. If you wish to supply a .ini file, write one and edit the supervisor config file for uWSGi to include it via the command line command in:
/etc/supervisor.d/kano_konnect-uwsgi.conf
Celery is also managed by supervisor. The integration into Django is specified in the file:
/srv/kano_konnect/current/kano_konnect/kano_konnect/celery.py
Tasks should be specified inside of the file::
/srv/kano_konnect/current/kano_konnect/kano_konnect/tasks.py
On the server, Celery requires rabbitmq to be running. Rabbit should start when the server starts and run automatically, but if it ever crashes it can be restarted with::
sudo service rabbitmq-server restart
Postgres is running as a service on the webserver. The “cluster” contains a database called “kano_konnect”. You can interact via psql by doing:
sudo -u postgres psql
The CI integration is currently broken. So code must be updated manually.
To update the repo, simply ssh into the server via something like:
ssh -i ~/.ec2/kano-konnect-key.pem<EMAIL_ADDRESS>Then do:
cd /srv/kano_konnect/current
sudo -u nobody ./pull.sh # github was giving me trouble with agent forwarding, so I added a deploy key for the nobody user
source /srv/kano_konnect/shared/env/bin/activate
cd kano_konnect/
# sync the database
sudo -u nobody python manage.py syncdb --settings=kano_konnect.settings.production
Then restart the servers:
sudo supervisorctl restart all

Sponsorships help bump up Man United Q1 core profit
LONDON, Nov 18 — Manchester United today posted a jump in first-quarter core earnings, boosted by increased revenue from sponsorship deals and as player wages fell after the English football club failed to qualify for the Uefa Champions League.
The 20-time English champions saw their revenue flat line in the quarter but stood by their annual revenue and core profit targets.
The club had warned in September that annual revenue would fall for the first time in five years and profit would also drop, as they will not be able to capitalise on Uefa’s broadcasting revenue distribution system.
“We have a clear vision in terms of football philosophy and recruitment,” Executive Vice Chairman Ed Woodward said. “We are particularly optimistic regarding the considerable young talent currently coming through.”
Manager Ole Gunnar Solskjaer has had to rely on players coming through the youth academy to try and turn the team’s fortunes around, putting the spotlight on academy graduates including Marcus Rashford, Scott McTominay and Mason Greenwood.
United are competing in the less lucrative Europa League this season and have endured a stuttering campaign so far in the Premier League, occupying seventh in the standings after 12 matches.
Revenue from broadcasting dropped by nearly a quarter, and the club said the majority of the full-year impact from missing out on the Champions League would occur in the second quarter.
Their core profit rose 18.4 per cent to £34.8 million (RM187.4 million) for the three months to September 30, as employee costs fell nearly 9 per cent.
Sponsorship revenue climbed 8.1 per cent to £53.6 million, largely due to new sponsorship deals with well-known brands such as Lego and Konami, as well as extra revenue from pre-season exhibition games. — Reuters


Largely considered cricket's greatest batsman, Sachin Tendulkar was born April 24, 1973, in Bombay, India, to a middle-class family, the youngest of four children. His father was a writer and a professor, while his mother worked for a life insurance company.
Named after his family's favorite music director, Sachin Dev Burman, Tendulkar wasn't a particularly gifted student, but he'd always shown himself to be a standout athlete. He was 11 years old when he was given his first cricket bat, and his talent in the sport was immediately apparent. At the age of 14, he scored 326 out of a world-record stand of 664 in a school match. As his accomplishments grew, he became a sort of cult figure among Bombay schoolboys.
After high school, Tendulkar enrolled at Kirti College, where his father also taught. The fact that he decided to go to the school where his father worked came as no surprise. Tendulkar's family is very close, and years after he'd achieved stardom and cricket fame, he continued to live next door to his parents.

You know what? I'll never drink coffee in the server room again.


When I think about the values that will help DBC students weather the oncoming immersion experience, I'm hardpressed to come up with more important ones than persistence and gratitude...
Persistence is a popular underdog value for good reason: it opens doors that wouldn't otherwise open. A million catch-phrases and famous quotes exist on the topic, and we could probably use a million more to remind us of persistence's virtues. Many of the phrases and quotes amount to this... It doesn't matter if we fall down. Falling down is not failure. In fact, falling down is essential for forward movement and progress. Not falling down indicates that we're stagnating. It's the getting up part where persistence comes in to play. And as long as we keep getting up, we're not failing, we're going through the necessary path of trial and error -- nature's great feedback mechanism -- to reach our goal.
Another value also popular but less widely held is that of gratitude. Being thankful for what we do have helps us in many ways. It keeps us focused on what we have, as opposed to what we don't have. That alone fosters a positive outlook. It reminds us to count our blessings and take stock of how good (God || The Universe || Life) has really been to us. There is much to be thankful for, on a daily basis, and there are always people who have it worse off than we do. Even those people objectively worse off than ourselves can be examples to us in the measure of their own gratitude.
Developers, or programmer types, are typically wired to look for errors in things. This is not a sadistic tendency, but one that in theory allows for quicker resolution and a better final product. This tendency we have carries over into our everyday lives of course, and in this area we would do well to exercise some moderation. Objectively, the glass is half empty, but it is also, every bit as much, half full.

Seat Adjustments is an optional feature allowing you to define adjustments to a resource's Max Seats setting. The adjustment can be applied based on day of the week, time of day, or day and time.
Initial Max Seats setting is done in the resource setup screen.
There are 3 ways to apply adjustments:
Note: Timeslots that begin or end in an adjustment area will have the adjustment applied.
For example, if an adjustment is set as 4:00-6:00, a slot that runs from 3:00 to 4:30 will have the adjustment applied.
Negative adjustments are supported and allow a reducution of Max Seats.
See help text beside individual settings.

Overview
Web development is the building and maintenance of websites; it’s the work that happens behind the scenes to make a website look great, work fast and perform well with a seamless user experience. Web developers, or ‘devs’, do this by using a variety of coding languages. The languages they use depends on the types of tasks they are preforming and the platforms on which they are working. Web development skills are in high demand worldwide and well paid too – making development a great career option. It is one of the easiest accessible higher paid fields as you do not need a traditional university degree to become qualified. The field of web development is generally broken down into front-end (the user-facing side) and back-end (the server side). Let’s delve into the details.
The first step is to decide which aspect of web development interests you and then start out with one programming language. For example, if you are interested in front end you can start by learning some HTML and CSS, then start working on projects as soon as you are comfortable with the basics. Our Web Developer Program is a perfect fit for this route. But others may suite you as well. It also helps to join a discussion group or community of other web developers, so that you can troubleshoot, discuss ideas and get inspiration.


Planning responsibilities
- Ensure that text alternatives are equivalents for non-text content.
- Text alternatives must convey the purpose of an image or function to provide an equivalent user experience. For instance, an appropriate text alternative for a search button would be “search” rather than “magnifying lens”.
- For every image, write alternative text that provides the information or function of the image. For purely decorative images, there is no need to write alternative text but the images need to be hidden correctly from assistive technology.
Tips for collaboration
- Designers, Editors and/or Content Managers know what non-text contents convey.
- Developers use semantic attributes/properties to provide text alternatives.
- QA testers know to test for appropriate text alternatives, including semantic code evaluation.
- Search Engine Optimizers (SEO) know how to maximize the increase in search engine visibility provided by text alternatives. However, the ability to leverage this increase cannot cause any text alternative guidelines to be broken.
Planning for each stage
How to get started early
- Providing text alternatives will help all users and maximize potentials by making non-text content machine-readable.
- Early project meetings need to discuss accessibility and the importance of improving the usability of the site for people with disabilities. This should include training on how to create good quality text alternatives.
- Decide who will create text alternatives for images and who will review and approve it.
- Appropriate alternative text is not an exact science. Some people prefer most images to have more detailed description; and others prefer much less description.
- Consider conducting usability testing on existing or similar products to better understand people's preferences.
How to remediate
- You don't usually see the alt text on a web page, it is in the web page markup.
- Every image should include text alternative in the code.
- If an image conveys information useful for interacting with or understanding the web page content, then it needs alternative text.
- If an image is just decorative and people don't need to know about the image, then it should be implemented so that assistive technologies will ignore it.
- Automated tests can tell you if alt is missing.
- To determine if the alternative text is appropriate, you need to see the image and judge it in context.
- The text needs to convey the same meaning as the image. That is, if someone cannot see the image, they get the important information from the image in the alternative text.
- Alternative text depends on context. For example, for an image of a dog on a kennel club website, the alt text might include the breed of the dog; however, the same image on a dog park website may be there just to make the page more attractive, and the image might not need any alt text (and should have null alt). One way to help think about appropriate alt text is: if you were helping someone read and interact with the web page and they cannot see it, what would you say about the image?
- Images that are functional — for example, images that initiate actions (like submit buttons) and linked images (like in navigation) — need alt text that is the functional equivalent.
- If there is text in the image — for example, in a logo — that text needs to be included in the alt text.
- If the image has complex information — such as charts or graphs — the image should have a short alt text to identify the image, and then the detailed description of the information should be provided elsewhere (for example, in a data table).

My interests are numerous, but the ones that really get me excited are music and technology.
From an early age I was captivated by technology and took apart every electronic device I could find. Today I practice that same fascination through software development. Whether it's consulting or a personal project, I'm typically cooking up something and keep a worklog that documents my weekly progress. It's a safe bet you can find me geeking out about software and design on Twitter and my programming blog.
Piano jazz standards, acoustic blues, and heavy metal electric guitar riffs all feed my soul. I have a humble studio and when I have long stretches of free time I'll record and produce my own music. Typically I don't have the patience for production, so I occasionally post unedited musical snippets on my YouTube channel.
I've always been fond of writing, but have not yet made a conscious effort to practice it consistently. My musings are a space to grow that skill more and posts may feature anything under the large umbrella of my interests.


class Shoppe::OrderItem
Public Class Methods
This allows you to add a product to the scoped order. For example Order.first.order_items.add_product(…). This will either increase the quantity of the value in the order or create a new item if one does not exist already.
@param ordered_item [Object] an object which implements the Shoppe::OrderableItem protocol @param quantity [Fixnum] the number of items to order @return [Shoppe::OrderItem]

Capture those stunning moments of your life and share full size pictures without loosing picture quality.
PicShake uses a simple and fun way to share pictures using phones shake gestures
PicShake lets you share those beautiful moments that are captured with your beloved family and friends.
We believe that sharing pictures should always be fun and easy. PicShake shifts the responsibility of sending pictures from one person, to the whole group receiving those pictures. With our app, when a picture is taken it is uploaded to the cloud with a password you pick and your friends within 500 meters can download the picture directly to their phone by using that password. You do not need to create a group, tag people online, or even have their contact information. Your friends get the picture without you doing all the work. This will change the whole photo sharing experience.
One other thing that makes PicShake unique is that most of the photo sharing apps on the market degrade the picture quality when it is shared. However, PicShake lets you share full size high quality pictures. What’s really neat about picshake is that if you upload several pictures with the same password and within the same range, you are essentially creating a private gallery. For instance you upload a picture and then your friend uploads another one with the same password. These two pictures get put together in a single gallery.
A picture taken today is a lifetime of yesterdays preserved for all the tomorrows.
To develop a deeper and more meaningful connection with consumers, we believe design must invite them to take part in the conversation.

Scratch
Scratch is a simple stack-based programming language implemented in ruby.
It is the ruby implementation of the language in this tutorial, originally in javascript.
Usage
Interactive Mode
You can run the scratch REPL by running bin/repl
in the folder where
you’ve cloned the repo. For windows, you might want to do ruby bin/repl
.
Language Features
Scratch is a stack based language. The language uses a stack to store data and runs operations on data from the stack.
At any moment you can print the stack using pstack
.
Adding items onto the stack
You can add numbers to the stack simply by entering the number and hitting enter. You can add several numbers seperated by a space.
Scratch:89sno9> 1
Scratch:89sno9> pstack
1
Scratch:89sno9> 2 3 5 2 90
Scratch:89sno9> pstack
1 2 3 5 2 90
Stack manipulation
There are several commands to manipulate the stack as shown below:
| Command | Description |
|---|---|
pstack |
Print the stack. |
print |
Print the top item in the stack. This drops the item from the stack. |
dup |
Duplicate the top item in the stack. |
swap |
Swap the top 2 items in the stack. |
drop |
Remove the top item in the stack. |
dropstack |
Clear the stack. |
You can mix and match commands and run them as a single command. Scratch executes one word at a time.
``` Scratch:89sno9> 19 Scratch:89sno9> print 19 Scratch:89sno9> pstack
Scratch:89sno9> 19 Scratch:89sno9> dup pstack 19 19 Scratch:89sno9> dropstack Scratch:89sno9> pstack
Scratch:89sno9> 19 dup dup drop 12 swap pstack 19 12 19 Scratch:89sno9> dropstack print == Error: This command requres at least 1 item on the stack ```
Simple Math
The scratch standard library has the simple arithmetic operators +
, -
, *
, &
and sqrt
.
These operate on the top 2 items in the stack (with the exception of sqrt
which operates on
the top item only).
Each of these commmands removes those items from the stack and places the result at the top of the stack.
``` Scratch:89sno9> 2 3 + print 5 Scratch:89sno9> pstack
Scratch:89sno9> 2 3 * Scratch:89sno9> pstack 6 Scratch:89sno9> 20 5 / 3 + print 7 (Twenty Divided by five, then take the quotient, plus three) ```
Testing
Clone this repository and run rake

This is the WebLab-Deusto creation wizard. With it, you can automatically generate your own WebLab-Deusto system, on which you can manage your users, grant them permissions on certain laboratories, etc.
The process is very simple: click on the Configure tab and fill the data related to your institution (university, secondary school, etc.). Then, click on the Deploy tab to fill the administrator data and deploy the system. Once deployed, you will be able to modify users (including the administrator data) and permissions, but not the parameters provided in the Configure panel. You may however change those by contacting us.
Enjoy!


My first week at DBC is almost complete and I've learned a ton. For my own sake, and the sake of you, dear reader, I am going to walk through the basics of git and GitHub, as well as some git commands you'll need to use in the command line.
Git is an incredibly handy open source version control system. Sooooooooo... what is that? Version control software allows you to save and record many versions of a project as you work on it, and access those different versions whenever you like. You have control of all of those versions. Get it? Version. Control. Version control!
This is obviously very handy for any project where you might make a mistake or bad choice and want to go back, but it is especially handy for coding, where one rogue character can mess up an entire project. With git you can just go back to a working version and try again.
Git helps you keep track of changes with commit messages and the git log. With each submitted change, or commit, a good programmer submits a commit message that explains exactly what was done. These commits and their messages are always accessible via the git log, which shows every commit since the initial one. Pretty nifty!
Github is an awesome way to store, track, collaborate on, and change your code. There are many benefits to using GitHub. For one, your work and all of your commits now exist online, which will save you if your computer crashes. The interface is excellent, and accessing your commits is incredibly easy. The interface also allows you to see exactly what was changed when you submit changes by using a helpful red/- and green/+ comparison. But perhaps GitHub's greatest strength is that it allows you to work collaboratively with people around the world on your work and theirs. GitHub is a social networking site (like Facebook), and if you like, you can make your work public, allowing people to copy, change, and add to your work. All of this exists at GitHub.com. Check it out!
- Navigate to your repository in the command line using the cd command line
- Create a branch: git co -b new-branch-name
- Make changes
- Check your git status: git status
- Add your files and changes to be committed: git add . (or the specific file name)
- Check your git status: git status
- Commit your changes and add a message: git commit -m "message"
- Check your git log: git log
- Navigate back to the master branch: git co master
- Pull the current master branch (in case a team member has made changes): git pull
- Navigate back to your new branch: git co new-branch-name
- Merge it with the master branch: git merge master
- Push your changes up to GitHub: git push origin new-branch-name
- Navigate to github.com
- Click pull request
- Confirm merge
- Delete the old branch (this is good organizational practice): git branch -d new-branch-name
- Git and GitHub rule.
- Learning the command line was super intimidating. It looks so advanced and complicated! But it was fairly simple, actually. I was glad to have some html knowledge and breeze through those few parts, because it was nice to feel a little ahead in one thing while wading through tons of new material.
- Oh man, I type like a baby. Or hey, I used to! Before DBC, I was typing with 2 fingers on each hand, and I was going pretty quickly, but I looked down at the keyboard a lot and topped out at about 45 wpm. So, I've been making a concerted effort to do the typing lessons and type like an adult human. I'm already typing faster and I never look down at the keyboard. It's great!
Okay, that's it for me. See you next week!
--Ian

A stable matching is a matching without rogue couples
There is always stable matching for men and women
Every man has a complete list of women ranked according to his preferences
Every woman has a complete list of men ranked according to her preferences
There is a marriage day
Everybody ends up married
All the marriages are stable
The mating ritual marries every man to his optimal spouse
The mating ritual marries every woman to her pessimal spouse
Generalization of the stable marriage problem
Initial algorithm was in use in 1952-1998 and favored hospitals
Works with couples, but there may exist no stable matching
Unmatched students and programs go through the process called SOAP
170.000 edge servers
~1300 networks
102 countries
~15-30% of all web traffic
Map units (IP address prefix, traffic class) and clusters instead of men and women
Map units rank clusters by performance: latency, packet loss, throughput, etc.
Clusters rank map units by cluster contract terms, IP addresses' locality to the autonomous system in which the cluster is deployed, etc.
Each map unit is associated with demand - the amount of content accesses that clients from that map unit are likely to generate; can vary rapidly in real-time as clients access more or less content
Each cluster has a notion of capacity that represents the maximum demand that the cluster may serve; capacity is dictated by processing power, memory and disk capacity, etc.
Unequal number of clusters and map units - tens of millions of map units versus thousands of clusters
Partial preference lists - map unit in Boston may never need to rank a cluster in Tokyo
Modeling integral demands and capacities - express demand and capacity as arbitrary integers
Leads and offices instead of men and women
Number of leads is not equal to number of offices
Each office has maximum capacity and range
Rank leads by the number of offices nearby
Rank offices by the number of leads they are already processing
Do not consider unreachable offices
Separate procedure for unmatched leads

Ebean is now aware of Spring boot runnable jar structure (for scanning the classpath). There is an example application showing:
This example does not show integration with Spring transactions (and instead uses Ebean's own transactions). Please
review the ebean-spring
project for that.
The ebean-spring provides a FactoryBean as well as integration with Spring transactions.
<@maven "io.ebean" "ebean-spring" "auto" "4" />
EbeanServerFactoryBean
is a spring FactoryBean that also holds a serverConfig.
It is expected to be used in conjunction with default-ebean-server.xml
which specifically
registers SpringAwareJdbcTransactionManager
as the external transaction manager on the ServerConfig.
SpringAwareJdbcTransactionManager
implements Ebean's ExternalTransactionManager API and provides the
integration into Spring transaction management.
SpringJdbcTransaction
extends Ebean's ExternalJdbcTransaction
and
is used by SpringAwareJdbcTransactionManager.
Rather than use the implementation provided in ebean-spring
you can write your
own Spring FactoryBean like the code below (or the spring boot EbeanFactoryBean example
Factory Bean (programmatic configuration of EbeanServer)).
/** * Simple Spring bean factory for creating the EbeanServer. */ public class MyEbeanServerFactory implements FactoryBean<|EbeanServer> { public EbeanServer getObject() throws Exception { return createEbeanServer(); } public Class> getObjectType() { return EbeanServer.class; } public boolean isSingleton() { return true; } /** * Create a EbeanServer instance. */ private EbeanServer createEbeanServer() { ServerConfig config = new ServerConfig(); config.setName("pg"); // load configuration from ebean.properties config.loadFromProperties(); config.setDefaultServer(true); ... // other programmatic configuration return EbeanServerFactory.create(config); } }


Turns out snakes don't like the cold.
We are resuming our progress after finals and winter holiday break from last semester. We have a few goals we are trying to complete this first week back.
My individual things I need to accomplish this upcoming week are finishing the regionGrabber method from last semester and to fully thread the push primitive for the coordinator.
When threading the push primitive I need to define clear start, stop and wait conditions so the coordinator can discern which stage we are in during the program. This function should be uniform across all motion primitives so the process is more streamlined.
So to recount the plan of attack for my upcoming week I need to finish the threading for the push primitive. My first step will be creating a script that integrates the push primitive process and the modeling process together. This will serve as my test script. Within this script I will need to thread the process so that it samples the image from the kinect at a faster rate than the rate of motion of the snake during execution. This will create a motion model that moves smoothly due to the multiple frame captures. Essentially the part of the process that accomplishes that is the one where it actually takes the picture of the design environment and cuts out the specific subset the method receives as an input. Lastly for the regionGrabber there is only one error. Due to it taking the kinect capture and sampling it then it takes in a lot of the background of the environment. In order to get rid of it I will have to do the computation to subtract the extraneous parts.
New Addition to the Team
We received a new team member for this semester and she will be taking over all things involving the coordinator this semester. Now our total team member count is at 5 people so the work can be divided up even more and increase the overall efficiency. Of course a learning curve exists when coming to the project for the first time, however, Ali has already been making great strides.


A track for couples facing self-doubt and insecurity
by Manila Standard ShowbizYoung singer-songwriter Jayda is back with another heartwarming tune through her self-penned song “Perfectly Imperfect,” a duet which she sang with The Voice Teens finalist Jeremy G.
The track, produced under Star Music, speaks about mutual love and appreciation between lovers. It revolves around the theme of loving someone without reservations despite their flaws and insecurities. It also promotes love that sees beyond physical attributes, a relationship that looks past all imperfections.
“Perfectly Imperfect” went through quite a journey, having undergone four arrangements before finally being recorded. The 16-year-old performer originally wrote it on her guitar while on her way home from a trip in Palawan when she was just 14 years old.
Apart from this single, Jayda also teamed up with Indonesian artist Renn Miko earlier this year for the song “Crazy About,” her first international collaboration. Meanwhile, her first EP In My Room was released last year, followed by her stint as Niall Horan’s opening act during his Manila tour at the MOA Arena.
Jayda is only one of the many talented artists under Star Music—a known home to many of the best OPM music of today from the country’s leading media and entertainment company, ABS-CBN.
On the other hand, The Voice Teens alum Jeremy Glinoga has since reinvented himself and is now known as multi-talented performer Jeremy G. He now guests regularly in ASAP Natin ‘To, and was also named as one of the ambassadors of technosport Hado, which was just recently launched in the Philippines.
Jayda and Jeremy G’s “Perfectly Imperfect” was released on all digital platforms on Friday, Nov. 15. Catch the premiere of its music video on Star Music’s YouTube channel on Monday (Nov.18).

This will show you the upcoming releases of certain shoes. Click the button below so that we can show you the dates of when the shoes come out.
Release DatesThis section will show all the shoes that are curently hyped up, in other words the most popular.
Most HypedThis section will show the most hyped up shoe of the month it is called the Air Jordan 4 “Bred” or "Black Cements". It is probaly the most hyped sneaker of the month of May. This pair of shoes was remade and released on May 4th of 2019, at a retail price of $140-$200 ($140 for Grade School). The Air Jordan 4 “Bred” or "Black Cements" was the first pair of sneakers to introduced several other embellishments that have become iconic. The first Air Jordan silhouette to feature mesh-netted overlays, and also boasted a unique support and lockdown system provided by the iconic “wings” on the lateral and medial sides. From a graphic standpoint, they also that introduced the now-omnipresent “Flight” concept to MJ’s signature line. And all those signature details, embellishments, and tech are brought together by the beautiful combination of black, grey, and fire red that gives the shoe its name.


Python feared to have escaped from East Kilbride home
She believes the snake, called Lillith, escaped her Calderwood enclosure on October 28
by Fraser N Wilson, https://www.dailyrecord.co.uk/authors/fraser-n-wilson/An anxious pet owner has launched an appeal for the return of her pet snake.
Aryanne Finnie contacted the News panicked about the whereabouts of her young Royal Python.
She believes the snake, called Lillith, escaped her enclosure in Burns Park in Calderwood on October 28.
And she admits she is “terrified” the snake may have made it out of the house and “possibly into someone else’s”.
Aryanne told us: “I know the fear and panic people have when it comes to loose snakes, which is why I am even more afraid something bad will happen to her if she has escaped the house.
“Lillith is a very distinctive looking snake – I have looked everywhere and I think going public is my only other option to make people aware she might be around.”
Aryanne has had her beloved pet for six-months. Lillith is still a baby at around eight-months-old.
Aryanne added: “She has a neurological disorder that comes with her genetics that makes her confused with her orientation and surroundings.
“Sometimes she thinks she’s upside down and is very clumsy, so she’s very special to me.”
If Lillith is out of the house, she would be looking for somewhere warm and cramped to curl up in. She is very friendly and very shy too.
“She is completely non-venomous and has never bitten or tried to strike at a human.”

How To Use This
The latest release of Symbiota has rolled out the ability to create customized label formats for printing. Check with your portal managers/admins if you have that option installed in your portal.
Label formats can be defined in a variety of ways:
- Directly in the database, as a property of the collection profile;
- Directly in the formats file, using JSON definitions;
- Via User Interface, through the Label Editor ('/collections/reports/labeljsoneditor.php').
This is a prototype designed to provide a more user-friendly way to create label formats. It is in the process of being integrated into Symbiota. Feedback is appreciated.
To access the Label Editor, you have to be logged in and have the necessary admin permissions:
- Find a collection for which you'd like to print labels (either in your User Profile or in the Sitemap, depending on the permissions you have).
- In the 'Data Editor Control Panel', click the 'Print Specimen Labels' link.
- Search for a few specimens (click 'Filter Specimen Records' button) and select the desired ones by clicking their checkboxes in the results.
- Scroll down to the 'Label Printing' area.
- Click the edit icon (pencil) next to the 'Label Profiles' option.
- Find the format you wish to modify or click the green plus icon in the upper right corner to create a new one.
- You can now enter your label definitions in the form. The
formats you're defining in this interface (the Symbiota Label Content Format Generator) will generate a JSON output that you have to paste in the 'JSON' field in the form.
- Click the "Save Label Format" and go back to your label printing module to find your format available for printing!
- Additionally, you can load an existing JSON format by pasting it into the text area below the preview and then clicking "Load JSON". Caveat: it can only read simple JSON formats such as those generated by this tool for the moment.
- In your label definition main form, you need to add the path to the label helper style sheet in "default CSS" like so:
../../css/symb/labelhelpers.css

I was born in Ohio and raised in NC, forever straddling the midwest and the south in both accent and temperament. I grew up surrounded by music, theater, and art, and a family who communicated through emotions.
My passion: I LOVE music - it's one of the most powerful and diverse methods for expression & communication. In the meantime, I get my fix by going to lots & lots of concerts. I'm at 160 and counting!
A fun fact: As a true New Yorker, I'm slightly embarrassed to say that I only learned how to ride a plain ol' stationary bike 1 year ago, and have yet to learn how to drive. But, the real takeaway is that I'm learning.
