Structural Testing of Active DataBases
Departamento de Computación, FCEyN, Universidad de Buenos Aires,
Active databases (ADBs) are databases that include active components or agents that can execute actions.
The rise of active databases in the picture of software development has a great impact on software systems and in the discipline of software engineering.
However, we still lack the foundations that are needed to adequately support this new tool.
These foundations are needed in order to properly apply known software engineering techniques to ADBs and systems that use them.
Among the methods and techniques used to improve quality, we count systematic testing.
In this work, we generalize structural testing techniques to ADB
We introduce a model of active databases, called dbgraph, suitable for
We show that dbgraphs can be used to generalize structural testing techniques for ADBs.
Moreover, we introduce several new structural criteria aimed at find errors in a set of rules for an ADB.
We also compare the strength of the coverage criteria presented in this work.

Supported Platforms: Microsoft Windows 2000 & XP
The first thing you'll want to do when you run XpanDesk is to set it up for how you want to work. Click the Options button at the bottom of the utility's window (also known as the deskview). Here you can specify how many desktops you'd like to have; whether you'd like the desktops to be accessible from the system tray or the desktop context menu, or both; if you'd like the deskview to dock and, if so, to which location (top, bottom, left, or right); and whether the deskview itself should have its own background image, which you can specify.
Once you've set up the global options, you'll then want to configure each desktop. From the deskview, select Configure next to the button for the corresponding desktop. The first option you can modify is the desktop name. You can give each desktop a unique name, which will be displayed on the button in the deskview and the desktop context menu. For example, you could name one desktop, "Web Tools" and another, "Music".
You also have the option to assign a hotkey to the desk, like Ctrl + Alt + 1. We've found this to be the easiest and most productive way to move between desktops. Rather than opening up the deskview and selecting the corresponding desk, clicking the system tray icon (which sequentially rotates through the desktops), or using the context menu on the desktop, using the hotkey for a specific desk is really the best way.
Each desktop can have its own specific wallpaper and color. Simply click Use custom desktop appearance and you can specify the wallpaper you'd like to use and whether you'd like it centered, tiled, or stretched. If you center the wallpaper, the border will be the selected color from the Desktop color dropdown. Or you can choose no wallpaper and just use a custom color.
Low resolutions can be great for word processing and e-mail programs, but they're an absolute drag with, for instance, Photoshop. On large graphics, you have to scroll the image within the window in order to work on individual parts. Why should you have to choose just one resolution? This new version of XpanDesk supports multiple resolutions, so you can have 800x600 for one desktop and 1024x768 in another (or whatever resolutions your monitor can support).
XpanDesk can also save your icon locations for a particular desktop. This is especially important if your desktops have varying resolutions. If desk 1 is 1024x768 and you switch to desk 2, which is 800x600, any icons that extend past the border of the 800x600 screen will automatically be moved by Windows to fit in the screen area. If you then switch back to desk 1, these icons would remain in the same place Windows moved them to on desk 2. So in order to keep your icons locked in the positions where they originally were (on the 1024x768 desk), you need to select Save and restore icon locations for this desktop.

A thorough instructional on how to build a locked down web kiosk from a Debian Linux installation on a Raspberry Pi. We’re going to install OpenCV on the Raspberry Pi for Python projects. The Ubuntu Server image is much smaller, you can install flavours of the Ubuntu Desktop on top of it, it gives you access to the Ubuntu CLI and by extension, all of the latest open source. Thanks for the PM's. By editing /etc/xdg/openbox/menu.xml and clearing out all the items between the tags, you can. Basically, what I want to do is start an openbox session on boot up and have openbox autostart a GUI application. However, because of its size it only works on the Raspberry Pi 4 models with 4GB or 8GB of RAM. Note that this script takes around 3 times more on Raspberry Pi 2 as compared to Raspberry Pi 3. Raspberry Pi is a credit-card sized computer that runs Linux and could be plugged into a PC monitor or TV. If you a buying a raspberry pi, buy a Raspberry Pi 3 or latest model. What you will find in this HowTo. If you have updated the firmware recently then you can skip this guide and jump straight to the flashing procedure. Unfortunately, the steps detailed here are out-of-date as of Feb 2020. When Openbox launches at startup it will run two scripts in the /etc/xdg/openbox folder. Thus: This article tells you how to install the current snapshot version of OpenBSD on the Raspberry Pi 3. First, I downloaded the Raspberry Pi Imager Tool for Windows and used it to install Pi OS onto the SD card. installing etcher is a very simple task.

Original article was published on Deep Learning on Medium
Intersection over Union — Object Detection Evaluation Technique
This article will describe the concept of IoU in any Object Detection Problem. It will also walk you through the application of the same through python code.
What is IoU ?
As we know, any object detection algorithm, be it RCNN, Faster RCNN or Mask RCNN, will always draw a bounding rectangular box around the object which we want to detect in an image.
IoU actually stands for Intersection over Union. It is basically an evaluation metric. Any algorithm that provides predicted bounding boxes as output can be evaluated using IoU.
In order to apply Intersection over Union to evaluate an object detector we need:
- The ground-truth bounding boxes (i.e., the hand labeled bounding boxes from the validation set that specify where in the image our object is). Technically Ground-Truth are the actual coordinates of the object that we get from it’s corresponding image’s annotation file (xml or csv).
- The predicted bounding boxes from our model.
Now, how do we draw this Ground-Truth Box manually ?
Although there are many open source annotation tool available in the Internet, I’ll be using the most commonly used tool here just for the demonstration purpose, i.e., LabelImg
Steps to be followed are as below:
- Open Command Line Terminal in your local PC and clone the git repository as shown below.
git clone https://github.com/tzutalin/labelImg.git
Alternatively, you can download the labelImg-master zip file directly from the github link above.
2. I am using a Windows Machine with Anaconda preinstalled. So, I just executed the commands below one by one.
3. It will open the LabelImg Application.
Click on Open Dir and browse to the folder which has all the training images.
4. Select an image from the file list and click on Create Rect Box.
5. Drag the mouse pointer to draw a rectangular box around the object and enter the class name. For my case, it is kangaroo. After that, click on the Save icon to save this annotated xml file.
6. Likewise, we have to create annotated xml files by labelling the objects for all the images.
For cases, where there are two kangaroos in an image, we’ll draw two boxes and name the classes as kangaroo for both the boxes.
For cases, where there is one kangaroo and one horse in an image, we’ll draw one box for the kangaroo and one for the horse and name the classes as kangaroo and horse respectively.
7. Now, if we open any of the xml files, we’ll be able to see the actual coordinates of the objects annotated.
In the above annotation xml file, we have two kangaroos present in one od the images.
Now let’s come back to the concept of IoU.
Formula for IoU
If IoU is greater than the threshold, let’s say (0.5), then the object is a kangaroo, else, it is not an object of our interest. So, for the above case, the object within the predicted box is not an object of our interest.
Now for the intersection area, we have to get the coordinates of the intersection rectangle in the python program.
Let us define the get_iou function.
Now as our get_iou function is ready, let us see how we can fetch the coordinates of the ground truth or actual boxes from the annotation file.
First, we need to convert the XML file to CSV
If there were two kangaroos in an image, then we would have got two rows in the converted CSV file, just like below.
Now, let’s loop through the rows (in our case, number of rows =1) and fetch the x and y coordinates for both the objects. After fetching, we will append the values to an array, named as bb1.
Just for the demonstration of IoU in this article, I am not going to actually predict the values for bb2 (predicted rectangular box coordinates) through any algorithm. Rather, I would be passing hard-coded values manually.
Now, let’s call the IoU function to check for the IoU values.
For images with two objects or kangaroos, we would have got two IoUs as shown below.
Let us now do the same process while simultaneously plotting the boxes for ground-truth (actual) and predicted coordinates, on the original image.
The calculated IoU is coming as 0.0149. Let us change the values of predicted rectangular box coordinates (bb2) and check again.
The new IoU value of the detected object is now showing as 0.6997
In real-time object detection problems, we set a threshold for the IoU value (0.5), as mentioned earlier, so that the predicted rectangular box appears only when the IoU value is above the threshold.
That’s it for this article. I hope by now, you have clearly understood of concept of IoU in object detection problems. In my subsequent articles, we would discuss, how to predict the values for the predicted rectangular box through various algorithms such as RCNN, Faster RCNN or Mask RCNN, instead of passing hard-coded values.
Thank you !!

I might cut.
Well I live in Australia and we get an end of year report card showing how well we did in every subject of both homework and classwork. Classwork also covers exams and so on. Anyway, you get a rating out of 4.0. 4.0 is the worst possible point average, where as 1.0 is the best. Each years i get around a 2.2 which isnt too bad. But this year if i do much worse and my dad punishes me in anyway, i might try cutting.
I already feel depressed all the time, mainly because i get in trouble a lot at school and so on. My friend tryed cutting, and he said it was really good.
So what do you guys think i should do?

HI I am experiencing a problem with the system clock. Basically the laptop in question, an asus, had its battery removed a while ago. A few months ago, I noticed something was wrong with the clock. Everytime I unplug the adapter - when the laptop is off - the system clock default to 00:00 and the date to 2009. This seems to have implications with negotiating the connection and browsing websites (I get a certificate error quite often). ANyway, I can easily reset the clock in the bios and it works fine, untill, again, I disconect the adapter. On booting, there is a message coming up, something about a file missing.
What do you guys reckon this is due to? Not entirely sure how to fix it. It looks like when the power source is cut off the clock goes crazy, so I am thinking to put the battery backk even if it doesn't hold any charge, and try with that. Failing that, what dco you reckon I should do?

Dan Horvath explains how function point analysis (FPA), in combination with other metrics, provides reliable and accurate measures that may be invaluable to an agile development organization.
Software development and maintenance can be a challenging endeavor. Whether and how you measure productivity and quality, as well as how you go about doing project estimation, are among the major concerns. Function Point Analysis (FPA), in combination with other metrics, provides reliable and accurate measures that may be invaluable to the organization. Together, these methods can reduce risk and ensure project success by providing an accurate account of the effort required to complete the project. Function points measure the amount of business functionality an information system provides to a user. Such measurement may take place before (as an estimate), during, or after the project development, as required.
Although FPA is recognized by the International Organization for Standardization (ISO) as an industry-standard measurement method, the use of new software tools, methods, and technologies raises questions about whether FPA is applicable as a measurement method. Many organizations use function points as part of their waterfall software or systems lifecycle, and FPA can work just as well with agile. This article, the first of a three-part series on how to use FPA to improve your software development process, will demonstrate that FPA is a valid measurement of agile software development.
History and Definitions
Software metrics and particularly FPA are closely linked with project management; measurement takes place before, during, and after various project phases. Project management, in turn, is intimately concerned with the software development methodology being used. Consequently, in order to produce accurate results when considering estimating techniques and productivity measurement, software metrics are often tied to the software development methodology.
A project is a temporary endeavor that has a defined beginning and end and is undertaken to meet unique, specific goals and objectives, generally for the purpose of causing required changes or adding value. The software product’s output is a product of some kind. Traditional waterfall software development methodologies fit well with this definition of a project. The concept of a beginning and end are essential to both the methodologies and the management of the project. Once a project is defined, software metrics may be gathered and applied to the overall measurement information. Project metrics are meaningless without well-defined projects.
Rapid Application Development
Software development methodologies were originally derived from some form of waterfall process, where one phase followed another. They began to evolve further in the 1990s, when Rapid Application Development (RAD) was developed by Dan Gielan and James Martin and gained popularity. RAD methodology uses minimal planning in favor of rapid prototyping. The "planning" of software developed using RAD is interleaved with writing the software itself. This generally enables RAD projects to be implemented in a shorter period of time.
There are several types of RAD methodologies, some of which are listed below. Although most of the methodologies foster the reuse of software, distributed development, and small team structure, many RAD practitioners recognize that there is no single “rapid” methodology that provides an order of magnitude of improvement over any other development methodology.
Application development using RAD generally favors smaller projects that can be developed in sizeable pieces. This has a considerable influence on the concept of a project, but agile, because of shorter release cycles and more rigorous definition, has an even greater impact.
Some of the “flavors” of RAD methodology include:
- Agile Software Development: Agile software development features extremely small release cycles by breaking up software projects into mini-increments. Real-time, face-to-face communication is ideal for agile software development. Documentation is developed when it needs to be developed, which may be at the completion of a project.
- Extreme Programming (XP): XP is a set of development practices, first defined by Kent Beck in the late 1990s, that features short iterations, close teamwork, and customer satisfaction. Although this terminology predates agile, it is now considered a form of agile.
- Joint Application Design/Development (JAD): JAD is closely related to RAD, the primary difference being that JAD emphasizes the crucial role of the customer, and customers are actively involved in design activities.
- Scrum: Like XP, Scrum terminology and definitions predate those of agile. Scrum is now considered one of the leading agile software development practices. Scrum development practices are reduced to a series of short iterations or sprints, in which teams are self-organized.
This article focuses on applying FPA to agile software development, but the same principles can be applied to all of the above methodologies.

In our previous post, we introduced you to the foundational concepts of Stack-Based and Tabbed Navigation, which are central to iOS app navigation. As we dive further in, our attention turns to two critical elements: data flow and data sharing. This post will explore the inner workings of how data seamlessly traverses through your app's navigation framework and how it's shared among different components. In a nutshell, by the end of this post we will know how to pass data between screens as well as how to share data between them using SwiftUI.
If you haven’t already, I recommend you check out our previous post introducing the basics of iOS navigation using SwiftUI.
Data Flow vs Data Sharing
Data Flow and Data Sharing are related concepts in app development, but they serve different purposes. Before we explore each in more detail it would be helpful to get a clearer understanding of each.
Data flow refers to the movement of data within an application, often in a unidirectional manner. It focuses on how data is passed between different parts or components of an app, typically in a structured and organized way.
Passing data from a parent view to a child view.
Managing the flow of user input through an app's logic.
Data sharing involves making data accessible to multiple parts of an application, often for collaboration or synchronization. Data sharing is particularly useful when multiple views or components need access to a common data source or when you want to maintain consistency across different parts of the app.
Sharing a user's authentication status or profile data across various views.
Allowing different tabs of a tabbed interface to access a common dataset.
In summary, data flow primarily deals with how data is passed and updated within an app, focusing on the flow of data from one point to another. Data sharing, on the other hand, deals with making data accessible and consistent across various parts of the app, allowing multiple components to work with the same dataset. While they are related, they serve different aspects of data management and communication within an application.
Data flow in Stack-Based Navigation
Continuing from the previous section, data flow thrives on structure and organization. One way to bring structure into our data flow is by making it unidirectional, where information moves in a single, clear direction. This approach enhances the scalability and maintainability of our applications. With unidirectional data flow, it becomes more straightforward to reason about data interactions and ensure the long-term health of our app.
In our previous introductory post, we learned how the hierarchical nature of Stack-Based navigation inherently provides a sense of structure. Consequently, when working with SwiftUI's NavigationStack, data flow often takes center stage. To shed further light on this concept, let's explore two common data flow scenarios encountered when using a navigation stack:
Passing data from a parent view to a child view
Passing data from an ancestor view to a descendant view deep in the navigation stack
Passing data from parent view to child view
The first case is generally the most common scenario encountered when using stack-based navigation. We have a parent screen that presents a child screen using a NavigationStack, however, the child screen needs some data from the parent screen in order to display the correct information. We can typically pass data directly from the first screen to the second through the initializer as shown in the code below:
In our example code above we pass the Article data needed by the ArticleDetailView directly through the initializer. This approach helps maintain a clear contract between the parent and child views, making your code more robust and easier to understand. However, in more complex navigation structures, you may encounter scenarios where data needs to be passed from an ancestor view down to a descendant view.
Passing data from ancestor view to descendant view
This is the second case which you may encounter when you have several screens added to your navigation stack. This scenario often arises in apps with complex hierarchies or when information must be passed across multiple screens deep within your application. There are two practical options in SwiftUI:
Pass data down through the initializers of each screen (as we did above)
Use SwiftUI’s @Environment decorator
Although the initializers of views offer a straightforward means of passing data, this approach can quickly become unwieldy, particularly as your navigation stack grows. Moreover, it becomes less practical when dealing with multiple data types or when not all descendant views rely on the same data. To address these challenges and simplify the data flow process, SwiftUI provides us with the powerful @Environment decorator. With @Environment, we can ensure that the right data is accessible to the right views without the need for explicit initializer-based passing.
Imagine we're building a note-taking app that allows users to organize their notes into various categories such as “Work”, “Personal”, and “Hobbies”. Each category has its own unique color theme to provide a visual distinction. All views within a category should make use of the same color corresponding to their category. Additionally, when users navigate into the details of individual notes, we want to display the current category name.
Here's where @Environment proves invaluable. By utilizing @Environment, we can effortlessly propagate the selected category's name and color theme throughout the view hierarchy, ensuring a cohesive and user-friendly experience across all notes within the same category.
First, we have to define the @Environment values we need. We start by subclassing EnvironmentKey to define keys by which to access the values in our environment. Then we extend the EnvironmentValues struct with a new property for each new value. Following is the code used to define the categoryColor environment value we will use later to propagate our category colors (categoryName follows exactly the same process):
Once we have our environment keys and properties defined, we can utilize them to pass data down from our root screen (ancestor view) as shown below:
Set the color and name values corresponding to the selected category.
Set the environment values for category color and name in our NavigationStack using the environment(_:_:) view modifier.
At this point, we have successfully placed the categoryColor and categoryName values within our NavigationStack's environment, ensuring that any subsequently added screens can readily access and utilize them.
Accessing the required data from child and descendant screens becomes trivial:
As we can see, we were able to pass two data types down our navigation stack effortlessly without needing to pollute the initializers of any of our views. Our code remains clean and more easily maintainable, yet we are able to support a more complex data flow scenario.
Now that we’ve covered data flow within the context of a navigation stack, it is now time to explore a common challenge involving tabbed navigation.
Data Sharing in Tabbed Navigation
Within the domain of tabbed navigation, the frequent necessity to seamlessly share data across diverse sections of our app becomes readily apparent. This demand often stems from the importance of maintaining data synchronized across tabs, as is evident with user profile settings. When users make adjustments to their settings, they anticipate immediate reflection of these changes across all facets of the app. Another example are e-commerce applications, where the shopping cart's accessibility and editability across various tabs is indispensable for a fluid and intuitive shopping experience.
To help understand how we can tackle the task of data sharing when using a TabView in SwiftUI, let’s imagine we are developing a health app. In this app we have a workouts tab, nutrition tab, and settings tab. In the workouts tab users can track exercises like running, cycling, etc. The nutrition tab is used to input foods and beverages users consume. Both tabs use units of measurement like miles for running and cups for water consumed. Now, we want to allow users to set their preferred measurement system like imperial vs metric through the settings tab. This setting should be reflected by the units used in the workouts and nutrition tabs.
As in the previous section above, we could use initializers to pass the shared data to each of our app’s tabs. But as we discussed, this method can quickly become unwieldy as the complexity of the amount and type of data we need to share increases. Luckily, we can use the cousin of @Environment, which is @EnvironmentObject.
@EnvironmentObject is a decorator similar to @Environment except that it holds objects that conform to ObservableObject. This is important for two reasons. First, it holds a reference type, meaning changes made in one tab can be seen by any other tab holding a reference to that object and vice versa. Second, any view with a reference to the ObservableObject will be invalidated when it changes. All this means is that any view with a reference to the EnvironmentObject can make changes to it and be certain that those updates will be reflected immediately wherever it is used. This leads to a consistent and responsive user experience across all sections of the app, making it easier for users to track their fitness goals.
The code below demonstrates how the root screen would set the environment object for UserProfileSettings in our TabView.
Initialize the UserProfileSettings object.
Supply the UserProfileSettings object to the view hierarchy using the environmentObject(_:) view modifier.
As with @Environment, the code above has now made the UserProfileSettings observable object available to all the views in the TabView via the @EnvironmentObject decorator.
The app's tabs now have easy access to the UserProfileSettings object and can read or edit it.
Remember, any view reading the UserProfileSettings object will be updated when ever the measurement system is updated from the settings tab. As soon as the measurement system is updated by users, the workouts tab and nutrition tab will reflect the change.
As we conclude the second leg in our journey through iOS navigation using SwiftUI, we have covered the basics by examining how to use a navigation stack and a tabbed interface in our first post, and in this post we learned how to manage data flow and data sharing through out our navigation framework in a clean and maintainable fashion. Still there is more to explore in the realm of iOS navigation with SwiftUI, as we will see in the subsequent posts of this series.

As we'll likely get an initial influx of new people now that Graduation is coming, I suggest we sort out some community guidelines in addition to the [faq] for us to be aware of before it happens.
Questions that are even slightly broad, off-topic, or open-ended - we've historically been lenient for a while, letting people have time to fix them. I propose we make the new guidelines to automatically close/vote to close, and then add a comment that if they fix it, they can flag for reopening. Stricter = less time wasted by people answering questions that are going to get closed, and the user may still be online when it happens. Thoughts?
We've had a few new users who sign in, add an answer which is a link to their business (sometimes subtly, sometimes very much NOT). I propose if they're just links, even if relevant, we delete. If they've added a sentence as to why it's useful, I propose we allow it, but add a comment that they should state that affiliation. If they've done both, we allow it. Thoughts?
Any immigration questions - please vote to close, and always include a link to the expatriates proposal to help. The sooner that gets off the ground, the better for us.
Chatty comments - aside from the infamous Palestine etc debates, we've generally allowed some chatty comments. Should we continue like we are, or should we always lock posts that are getting chatty comments and refer them to the chat room?
The [FAQ]. If you have a chance, please re-read it, or even just pick one section. If there's an ambiguity or somewhere where you feel the community opinion has changed over time as we've matured this site, suggest some changes.
Tag wikis / tags - any changes we want to do about these going forward? Any thoughts on country vs city etc? (like the infamous georgia-country tag?)
Above all, if anyone sees answers, questions, comments that shouldn't be there, please flag them for moderators. Those with high rep can also click review at the top and review new users' additions, I believe, although I'm not sure on the threshold for that.
Any more comments, ideas or suggestions?

Keep SPAM free all your POP3 e-mail boxes.
Do not waste time and money download the spam messages, simply delete them
on the server
Are you concerned because your email box has 20 megabytes of messages? No
problem. KillSpam downloads only the email header, allowing you to read the
subject, date and several message lines. This allows you to delete Spam
messages and only download emails you want to read..
KillSpam does not execute script, which means you are protected from script
Interceptor Grid Filter, with this feature KILLSPAM automatic detect and
delete messages that you are declared SPAM or Virus. You indicated the
undesirable messages writing their subject in the interceptor grid. (KillSpam
scans the messages subject and those that match with interceptor grid are
delete. The match criteria can be exact, partial, case sensitive or case
insensible. Also you can filter by address or the whole spammer domain.
KillSpam can filter messages by sender address. It scans the addresses of
incoming emails and compares them to unwanted addresses defined in the Filter
Address Grid. If the filter and the addresses match, the messages are deleted.
The KillSpam Watcher is a program that works in tandem with KillSpam,from
backgrpound, automatically checking email accounts at regular (customizable)
intervals and alerting you if you have messages. Watcher does not download any
messages, but only indicates the number of emails, their size and to which
account they've been sent. The Watcher is connected to KillSpam so you can run

C&ESAR follows a 3 steps submission process (abstract, proposal, final version). Evaluation and selection is done on the proposal and final version steps. During the proposal step, a selective evaluation is done with a low selection rate on a detailed outline of the proposed article (or directly on the final version if a final version is submitted as proposal). During the final version step, an evaluation with a high selection rate is done on the final version of the accepted proposals.
- First step (abstract): title, authors and abstract of the proposals have to be registered no later than Wednesday, May 10, 2023 on EasyChair: https://easychair.org/conferences/?conf=cesar2023.
- Second step (proposal): proposals (3 to 16 pages for all types of papers) have to be submitted as a PDF file no later than Wednesday, May 17, 2023 via EasyChair. Authors will be notified of their proposal preselection by Wednesday, June 28, 2023 (a final selection will be made on the final version).
- Regular paper: If desired, authors can already submit a complete paper of up to 16 pages. However, reviewers will not be required to invest more efforts at this stage than they would for a 6 pages proposal.
- Short paper: If desired, authors can already submit a complete paper of up to 8 pages. However, reviewers will not be required to invest more efforts at this stage than they would for a 6 pages proposal.
- Extended abstract proposals must: be explicitly identified as such by the mention “(extended abstract)” in their title; explicitly identify and cite the original publication; and, contain an appendix containing the (anonymized) comments made by the reviewers of the original publication. If desired, at this stage, authors can submit the PDF of the original article instead of the PDF of a summary. However, reviewers will not be required to invest more efforts at this stage than they would for a 6 pages summary.
- Third step (final version): authors of preselected papers have to upload the final version of their paper on EasyChair by Wednesday, August 30, 2023. Authors of preselected papers commit to address reviewers’ comments in this final version. A final selection with a really high selection rate is performed at this stage.

About the content
What is fluid-solid interactions ? It is what happens when the motions of a fluid and of a solid are somehow coupled. This happens all the time, around you when leaves flutter in the wind, inside you when your heart beats, above you when wings of a plane vibrate, under the sea... The idea behind this MOOC is to give you the basic tools to be able to predict and eventually mitigate things called flutter, galloping, sloshing, vortex-induced vibrations, added mass, to cite a few. We are going to consider any possible domains of applications such as civil engineering, aerospace engineering, nuclear engineering , ocean engineering, biomechanics and even food processing ! This is why we called the course “Fundamentals of Fluid Solid Interactions ”. There are so many phenomena and so many models that we need to work together on the basic mechanisms . If you want to see how fluid-solid interactions work, and be able to use that knowledge, join us ! A first session of the course was run in early 2016, with learners from over 100 countries. It is now available with subtitles, in English and now in Chinese. See the video at http://goo.gl/YKSMnD
- Week 1 - Fundamentals
- Week 2 - A solid with a still fluid
- Week 3 - Viscosity and gravity effects
- Week 4 - Coupling with a fast flow
- Week 5 - Coupling with a slow flow
- Week 6 - Coupling with any flow

Delete and Re-install the Nginx in the Odoo server
Sometimes, due to some unforeseen circumstances, there could be issues with the Https certificate in the Odoo installation server. The errors may be varies and the quick fix is just to remove the nginx and install it again in a clean way.
sudo apt-get remove nginx nginx-common sudo apt-get purge nginx nginx-common
After that, just re-install the nginx and the HTTPS (eg, let's encrypt).

A crontab file is a simple text file containing a list of commands meant to be run at specified times. … The commands in the crontab file (and their run times) are checked by the cron daemon, which executes them in the system background. Each user (including root) has a crontab file.
What is the use of crontab?
The crontab is a list of commands that you want to run on a regular schedule, and also the name of the command used to manage that list. Crontab stands for “cron table, ” because it uses the job scheduler cron to execute tasks; cron itself is named after “chronos, ” the Greek word for time.

Why is crontab bad?
The problem is that they were using the wrong tool. Cron is good for simple tasks that run rarely. … Some warning signs that a cron job will overrun itself: If it has any dependencies on other machines, chances are one of them will be down or slow and the job will take an unexpectedly long time to run.
What is a crontab file and what is it used for?
crontab files (cron table) tells cron what to run and when to run it and is stored for users in /var/spool/cron, with the crontab name matching the username. The administrators’ files are kept in /etc/crontab, and there is a /etc/cron. d directory that programs can use to store their own schedule files.
How do I see crontab list?
To verify that a crontab file exists for a user, use the ls -l command in the /var/spool/cron/crontabs directory. For example, the following display shows that crontab files exist for users smith and jones. Verify the contents of user’s crontab file by using crontab -l as described in “How to Display a crontab File”.
How do I know if crontab is working?
To verify whether the this job got executed successfully or not, check the /var/log/cron file, which contains information about all the cron jobs that gets executed in your system. As you see from the following output, john’s cron job got executed succesfully.

How do I know if a cron job is successful in Ubuntu?
4 Answers. If you want to know if it’s running you can do something like sudo systemctl status cron or ps aux | grep cron .
Is crontab expensive?
2 Answers. Are cron jobs heavy and expensive processes that consume a lot of resources? Not unless you make them like that. The cron process itself is very lightweight.
Is running a cron job every minute bad?
“Cron” will run your job every 1 minute (maximum). This carries some overhead of starting a new process, loading data files etc. However, starting a new process will avoid memory leaks (because when the old process exits, it releases any leaked resources). So there is a performance / robustness trade-off.
Is cron job safe?
2 Answers. In essence it’s secure, but also it is another way for an attacker to, once compromised the system, make some backdoor persistent and/or auto-open it anytime you close it. You can use the files /etc/cron.

OCR and Regular Expressions
Most of OCR data is not useful and might slow down the Full-Text search. Consider adding options for extracting specific values from OCR data using regular expressions. These values can be used to index the document, and the rest of OCR data can be ignored which will minimize the size of Dokmee database.
For example, in my case I know that a customer account number can only be 9 digits and always starts with "10", so when scanning a subscription form, the account number can be identified easily with regular expression.

Most of the App you use in day to day life is Machine Learning enables. It is really difficult to deploy and manage Machine Learning applications in your own environment. Specially Machine learning-based Applications are quite resourced consuming in terms of hardware requirements. I found the majority of people work in AI-based company to support the infrastructure behind such applications. To overcome this problem we have good news. We have some cloud-based solutions in the market where you can run and deploy your ML-based application without any headache of managing server and all. Even you will get most of the preprepared code base. The article Top 5 Cloud Platform where you get Machine Learning as a service is full of relevant information over this interesting topic.[toc]
Top 5 Cloud Platform for Machine Learning as a service-
Cloud Platform which provides ML as service offers hardware to run and your code with dependencies. I mean suppose you build some Intelligent App on the top of TensorFlow and some other python dependencies. You may directly run in this cloud-based platform. These Platforms are scalable as well. I mean, you have to pay according to your usages and when you need more bandwidth support. It also helps in that. Before starting I would like to inform you, Please do not take the order as ranking. It is really difficult to give rank them because all 5 are best.
Amazon is really rocking. Back to Back Amazon is providing simpler technical solutions for complex things. Machine Learning is no more an exception. It is really easier to create a Machine Learning model using Amazon Machine Learning. They provide a very simpler API interface to train and predict your data. The pricing model for AWS Machine Learning is also quite interesting. You only need to pay based on usages. Actually AWS provide other infra solution like S3, Dynamo DB which make the development quite easy.
From the very beginning, I have told it is not lesser than AWS ML services or any other else. Just because I put it on second, it does not mean to say Microsoft Azure Machine Learning Studio has fewer features than Amazing services for ML. I found its drag and drop feature most user friendly than other Machine Learning as a service provider. This drag and drop reduce the necessity of coding expertise in data science.
When it comes to cloud and AI, We should not underestimate Google. Google already providing so many AI-based solutions to us. Google’s CLOUD MACHINE LEARNING ENGINE is an amazing Machine Learning as a service provider in the term of cost and performance. Most of the open-source libraries in Data Science are provided and backed by Google itself like TensorFlow etc. You can leverage them in CLOUD MACHINE LEARNING ENGINE.
IBM Watson is one of the most popular cloud solution providers in the corporate world . Especially I like their text analytics and NLP solution most. Although it’s only my preference. I found very accurate and easy chatbot development using IBM Watson.
BigML is not a big name in the cloud or platform as a service provider but it really effective and specific to Machine Learning. I think you should invest some time to read their features and functionality. It is cost-effective and performance-oriented too. It supports multiple cross-functional data sources as well.
We are living in a time where every next five years in technology is a new era. AI is capturing most of the knowledge base jobs. Now, these Machine Learning as a service is again an initiative to boost this process.
The intent of writing this article to give you an overview of Machine Learning as a service and available options. I have tried to demonstrate them in very lesser words. That is why I did not mention pricing and other details in this article. I will recommend you to visit their website. It will help you to mine more effective information. I hope you like this article. In case you have some other suggestion on Machine Learning as a service option for us. Please comment.

If you want to prevent auto-correct just once, tap the text box just after the word you're writing and that should cancel auto-correct.
If you want to undo an auto-correct you just allowed by mistake, tap on the word that changed and the first suggestion should be your original word.
Go to settings > Keyboard > typing settings > tap language press to change > uncheck correct misspelt words.
Now auto-correct will be turned off entirely. There doesn't seem to be a way to turn of auto-correct for just one word unless you add it into the dictionary.
Unfortunately it seems that there isn't any "standard" way to reset the dictionary in Windows 10 Mobile. Hopefully this will be added back in soon. I don't want to try this for fear it will actually work, but you could try adding a different keyboard, removing your default one, then reinstalling it.
UPDATE: A post recently published by Microsoft states that ...
Go to Settings > Time & Language > Keyboard and tap on your keyboard in the list of keyboards. There you will find all autocorrect options. I believe "Correct misspelled words" is the setting you want to turn off.
Here's a related question.
It's not the same on Windows 10 Mobile but here's what I found:
Selecting on the word after it was auto-corrected suggests my spelling.After choosing my spelling the force-correct for that word appears to be disabled for the current email. I hope it's the same for other document types.
Tapping right after the word, before it's ...
Not possible in this release, sorry.
If you want to send feedback to Microsoft about this, I've listed a number of feedback routes for wp on this page - http://dfwiki.devfish.net/technology.Microsoft-feedback-routes.ashx .
Windows 10 Mobile sometimes deviates from the settings of WP8.1 and it is very common for Bluetooth as well. What you can do is:
Update your phone to the latest build of OS.
Make sure that keyboard stuff for your selected language is downloaded. If not go to language settings and add that keyboard.
Long tap the lower right toggle key of keyboard then go to ...
You can change the word's case by selecting it and then press the SHIFT key on your keyboard. So let your device write "LinkedIn", select the word and change the case with SHIFT until you get "linkedin". I often use it on my Lumia 1020 because it always suggests "Smartphone" instead of "smartphone".
I have the same problem, it's so annoying. I don't want to turn off autocorrect, I just want it to stop autocorrecting correct words to stupid words, eg long to Lon, if to I.
Just typing normally, not WordFlow.
Language is English (New Zealand)
Keyboard is English (UK)
I've just reset suggestions under keyboard\advanced, and retyped the same message (in ...
One workaround is to use accented letters where there should be any. For example, replacing the u in F*ck with ū results in a word which can be added to the dictionary and will happily be suggested by the keyboard.
No, currently it is not possible to change the SIP (Software Input Panel, or on screen keyboard) in any way on Windows Phone 7. This means: no Swype, unless Microsoft adds it (or a way to customize SIPs) to any next version.

REDWOOD CITY, Calif., Nov. 15, 2012 /PRNewswire/ -- Many organizations developing Big Data applications first focus on trying to control, manage and secure the burgeoning volumes of data being generated. However, that step just scratches the surface of unlocking the data's ability to power competitive advantage. It is only when these multi-structured data stores become accessible to search and discovery that the information is transformed into corporate assets from which business insights can be derived and true value can be delivered to the organization. To develop these insights, robust search capability must be built into Big Data applications from the beginning, not added on as an after-thought.
LucidWorks, the trusted name in Search, Discovery and Analytics, today announced the general availability of LucidWorks Big Data™, an application development platform that integrates search capabilities into the foundational layer of Big Data implementations. Built on a foundation of key Apache open source projects, LucidWorks Big Data enables organizations to quickly uncover, access and evaluate large volumes of previously dark data in order to make more informed, better business decisions. Using LucidWorks Big Data, organizations have been able to attain insights that were previously locked away in their vast data stores, honing their competitive edge and slashing the time it takes to meet their organizations' goals.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...

The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...

If you’re a hard core Windows Insider, you’ll want to be one of the first to know when new Insider Builds are available for download and corresponding blog posts go up. You can always watch @donasarkars Twitter stream (and check the hints that builds are coming in images she posts), but if you have Hue or LIFX connected bulbs, you can use IFTTT to set up an Applet (used to be called a recipe) to get a visual alert.
While Microsoft’s response to the SIMPLO issue has been restricted to “working on a possible software fix”, customers are starting to report that even when plugged in, their SP3 tablets shut down. In essence, they can’t use their Surface Pro 3’s at all. This seems to happen when the amount of usable battery fully charged falls below a certain point, and as the days continue without a fix, more and more customers will have unusable devices. I don’t see that they will be able to keep their devices running long enough to even apply a software fix, should one actually become available. These customers are trapped. Microsoft won’t swap them out, and some are paying the usurious $450 out of warranty exchange fee. Note that Microsoft committed to a $200 battery replacement program on a Reddit AMA https://www.reddit.com/r/IAmA/comments/26m9cu/we_are_panos_panay_and_the_surface_team_at/chsei5u but has refused to honor this or even comment on it. (And as an aside, Apple charges $129 to replace an out of warranty battery.)
Microsoft told customers in the same Reddit AMA https://www.reddit.com/r/IAmA/comments/26m9cu/we_are_panos_panay_and_the_surface_team_at/chse7pn that “the battery can get charged daily (5 days a week) for over 4.5 years and still maintain 80% capacity”. Again, customers are responding in the thread that they can’t even use their devices while connected or docked.
I checked my sent email and note that as a Community Forum Moderator that I brought it to the attention of Microsoft on March 3, 2016. And a couple of times thereafter. I saw the trending that early.
And as of Saturday, March 6, afflicted Microsoft customers have not had a single update on the situation since the initial “we think we can fix in software and are working on a fix”.
Microsoft is "suspending" emails (because of the Canadian SPAM law effective 7/1). I found these REALLY useful. I’m sure others did as well.
Notice to IT professionals:
As of July 1, 2014, due to changing governmental policies concerning
the issuance of automated electronic messaging, Microsoft is
suspending the use of email notifications that announce the
* Security bulletin advance notifications
* Security bulletin summaries
* New security advisories and bulletins
* Major and minor revisions to security advisories and bulletins
In lieu of email notifications, you can subscribe to one or more of
the RSS feeds described on the Security TechCenter website.
For more information, or to sign up for an RSS feed, visit the
Microsoft Technical Security Notifications webpage at
So then I looked at the page referenced above. My "quick and dirty" very basic ‘Security Notifications from Microsoft Feed Reader’ app is now available in the Windows Store. http://apps.microsoft.com/windows/app/security-notifications-from/f5459c09-6233-4100-bfe1-d198111fc30b
I hope that Microsoft reinstates the emails after they figure out how to exclude Canadian customers who don’t want to receive this important information.
Things always blow up on a holiday weekend. Just when I thought the replacement HP Envy was the machine I’d be using for the next (hopefully) 5 years or so, trouble came knocking at my door. Yesterday morning, I had breakfast, hibernated the machine. Took a shower, got dressed. Maybe 45 minutes elapsed time. When I turned on the machine again I saw this ugly blue UEFI you’re totally screwed screen.
Burnt a Ubuntu DVD to run Ubuntu FROM DVD on my server. It seemed to indicate a hibernate issue (?).
I sent the blue screen image to my new contact (the Director Signature Experience Labs) from Microsoft Store within minutes of seeing it appear. He called me. Yup, on a Sunday, a holiday weekend, 7am Redmond time, within 15 minutes of my emailing the sad news. While were talking, I booted to advanced recovery and tried to run some powercfg cmds to delete the hibernate file, but they are apparently no longer supported. However, when I exited the machine surprised me and BOOTED into windows. I immediately started copying my data off (and spent the balance of the day yesterday getting my data copied off the HP onto two separate external devices to have redundancy).
I had met with him personally (the Microsoft Director, Signature Experience Labs), just last Wednesday when he came to collect the two machines that were “rejects” (one was the original bad hardware HP Envy 17 and the second was a miss-shipped 15 inch laptop from the same family). During lunch last week, we were discussing various laptops and I had mentioned that I had also been looking at the ASUS ROG 17 incher with the same specs (except for the touch screen) but since there weren’t any in the stores (mail order only I guess, I wasn’t all that keen on getting something sight unseen. Even Best Buy didn’t have any from that family to check out (just to look, feel, etc., not to buy from them). We discussed whether there is an issue with this HP ENVY TouchSmart 17-j141nr model machine (they don’t have enough data on returns) which is now my feeling. He is replacing this HP machine with the ASUS ROG-G750JS-DS71. (We agreed that two lemons are more than enough and trying to see if a third unit would be disaster free wasn’t a good game plan).
The reviews of the AUS ROG G750JS-DS71 everywhere are pretty awesome. I had looked at this computer before purchasing the HP but couldn’t justify the additional $$ for the ASUS. I’m going to have to go through all the setup stuff again, upgrade to 8.1 update 1, update to the Windows Media Center Pro feature pack, install my apps, copy in my data. Will probably take two days plus to set up the ASUS. Which I am hoping will arrive this week. I’ll hopefully have shipping details tomorrow.
Subtitle: A Signature PC should not behave this way or require this amount of manipulation. Not to mention that an average person would never be able to get through this.
A very old (in computer years) computer from the XP years that I’d been updating (hard drive, RAM, video card, network card, and of course Windows Operating System) (it was running 8.1 updated completely) finally gave up the ghost. It was an old clunker by today’s standards, and I had been using it for development and testing work. I’d been expecting this and had been doing some research for a few weeks. I’d already decided on a 17 inch laptop as a desktop replacement and I was loathe to order something I couldn’t test first or that came with bloatware, crapware, and things of that ilk. I’ve been to out almost local Microsoft Store enough times to know that the signature PC’s there were probably my best choice. And decided on an HP Envy 17 that appeared to be “fully loaded”.
The nice man that waited on me showed me a similar (less powerful) model that was on display. I decided that if testing that model proved acceptable, that the higher end model would be as good or better. On the negative side, the sales person was unsure of the specs of the higher end machine. I asked if it had a 5400 or 7200 speed hard drive (he had to look it up). I also asked if the higher end model had Windows 8.1 or Windows 8.1 Pro (the down level demo I was testing did not have Pro) and he replied affirmatively.
The demo seemed to be quite responsive, even on the store’s not so wonderful wireless internet connection. I wasn’t absolutely crazy about the gesture enabled trackpad and mouse functions, but knew I’d be purchasing/using a separate Arc Touch Mouse most of the time and that I could turn off and adjust trackpad functionality. Backlit keyboard was a plus. The keyboard itself is so-so but usable (I still think that no one has equaled the ThinkPad keyboards). After about twenty minutes I decided to pull the trigger and purchase.
The box came out from the back of the store. NOT Windows 8.1 Pro, only Core. I complained. I asked for a discount to offset the need to buy an upgrade key. The assistant store manager said yes to that in seconds (the store manager, who I know, was on vacation) and did some magic with prices to effectively reduce the cost by the amount needed to offset the Pro Pack Upgrade. Home I went, laptop in hand.
Arriving home, I plugged in and spent a couple of hours first applying the Pro with Media Center upgrade and then hitting Windows Update about 8 times until I was fully updated to 8.1, Update 1 (or whatever it is officially called).
I walked away to have lunch.
Problem #1: When I came back, the laptop was displaying an ominous black screen showing Boot Device Not Found Please install an Operating System. Held down the power button, did a few more things, started downloading my apps from the Windows Store. Went back to the desktop. Had two more instances of Boot Device Not Found Please install an Operating System. A web search for “hp envy operating system not found” turns up and ungodly number of hits. Most of which are folks who can’t get their computers to boot at all. That was not my problem. After some thought, I went hunting for a BIOS upgrade. Which I found and applied.
Problem #2: Under heavy network load (over 802.1ac wireless), I had some complete lockups. I went hunting for a driver update on the HP site. Found one for this specific model and applied it.
Problem #3: After performing the Windows 8.1, Update 1 update, Bluetooth went missing. It was completely gone from Device Manager as well. While I couldn’t find anything specific to the model laptop I had, I did find http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/Bluetooth-missing-HP-ENVY-15-j026tx-Windows-8-1/td-p/3753454. After some more searching, I figured out that I should try https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23761. Yes, that worked. Or at least I see Bluetooth in devman and have a functional BT task tray icon.
Problem #4: The HP Assistant Program finds newer drivers that those listed for the product page for this model laptop. It found an even newer Intel Wireless drive for the AC NIC. Suggests that it is a waste of time to use drivers from the product page. HP should be ashamed. If you have drivers, HP folks, keep your site updated.
Problem #5: I installed all my modern apps from synced profile. I then got all the Windows Store Updates for these apps. Skype and Bing News won’t install and error with 0x80073cf9. I can install other apps and update other apps. I uninstalled the “old” versions. Now I have none. I ran the PowerShell script to remove windows store apps and these two do NOT appear on the list. It’s not corrupted files, I’ve sfc /scannow’d and tried the standard wsreset, license sync, and it appears I am not alone. I do have the desktop app and there are other News Apps, so it is not the end of the world.
Problem #6: Locks up when accessing an SDXC card in the media reader slot. I’ve got an external card reader that works, but gee whiz…
I’ve got a thirty day return window and have resolved most of my issues. I’ve spent the past day and a half installing my apps and so on. I want this to be a keeper. I’m hoping I’m over the hump. HP should be ashamed for sure. And I’m hoping that the Microsoft Store folks leaern something from this.

Steps in filling a DMCA notice
You might be thinking, when will I ever use this? Well I'm in the process right now so I'll be walking through it myself.
First things first, if you're able to grab ahold of any IPs related to the rip, ban them. (In my case caught the person on live chat).
Secondly, if you know the URL (again in my case the live chat picked up where they uploaded it to), copy it and immediately do a whois search to find out who owns the domain.
Next, copy and paste it into a notepad for later use.
Ping the IP copy the IP address (using mark or whatever) and go back to google find an IP lookup service and look up who owns the IP (most will say the service provider)
Paste the IP into the notepad and of course paste any other info such as any e-mails attached (ex firstname.lastname@example.org)
Now grab a DMCA template, I used one from here which is very well written:
DMCA Notification Template - Copyright Law and SEO - McAnerin International Inc.
Grab the ISP one as it was most approiate.
Fill it in replacing the example text with your own stuff. Change the dates!
Login to your webmail (use email@example.com or something similar to resemble that you are indeed the owner)
Copy the contents of the document, paste it into the e-mail.
Attach the document to the e-mail and send it to the firstname.lastname@example.org address (whatever it is).
Wait until you get a response and of course keep checking each day and ensure to keep checking (proxies are a good idea to keep your IP from being blacklisted and should help keep you anonymous when you go for the kill).
If content is removed, keep checking in like 3 days later or so, if content reappears, send second notice just like the first but put in there that it is the second notice and that if it isn't removed you will pursue legal action.
Removed? Good check weekely still just in case, not removed? Ask an attourney for legal advice. If the entire thing is international (ex Malaysia or Sweeden) then you're pretty much screwed at the moment. Worth a shot though I guess. And of course you can submit one through the mail to Google if you include the search terms that infringing results come up on, haven't tried it yet so no idea.
Example that I used:
hostingworld.co.uk (infringing site)
Web Hosting, VPS, and Dedicated Servers by Host Mist (my site)

Microsoft Silverlight Vulnerability Leads To Malware Infections
Do you have Silverlight installed on your computer? The Microsoft product, similar to Adobe Flash, is used for running internet applications, most notably the streaming video client on Netflix. Subscribers alone account for 40-million Silverlight users worldwide. As Zeljka Zorz of HelpNet Security reports, all of these users are at risk of becoming a victim of a malware attack that exploits a critical vulnerability in Silverlight.
The malware, which could allow remote code execution, finds it way onto your machine when you visit an infected website. This website could be specifically set-up by hackers to infect unsuspecting users, it could be a compromised site that’s infecting users without the owners knowledge, or a site that allows user submitted content.
When you land on one of these websites, an Angler exploit kit, which is a tool used by hackers, determines what version of Silverlight you have installed. It determines whether you are vulnerable to an attack and, if so, the malware is downloaded to your computer.
The reason the Angler is needed is because Microsoft has already released a patch that fixes the security flaw being exploited. However, a number of users fail to update and are still using out-dated versions of Silverlight. If you’re using Silverlight, be sure you update to close vulnerabilities that could otherwise lead to a malware infection. If you don’t use Silverlight, but have it installed, you can remove it completely to protect yourself from this attack.
This is another example of why it’s important to keep all applications up to date and install each patch when it’s released. Enabling automatic updates for trusted applications makes this job easier.
If you have experienced a malware attack and your computer’s performance is suffering, bring your machine to Geek Rescue or call us at 918-369-4335.November 19th, 2013

Previous releases of this SDK have been in the form of an Eclipse plugin exclusively. Starting with version 10.2, the SDK has been expanded to include the API libraries and developer tools required to build apps.
Developing ArcGIS applications for Android is simplified by a group of Eclipse plugins provided with the SDK, ArcGIS for Android Core and ArcGIS for Android Doc and Samples. These plugins provide a rich set of tools, documentation, and samples to help developers create applications using the ArcGIS Runtime SDK for Android. The instructions below can be used for Eclipse with ADT plugin or the ADT Bundle.
The repository can be installed either by downloading in Eclipse via a public updatesite or with the local plugin that comes with the SDK. The workflow for both are offered below:Download the ArcGIS Android Eclipse plugin
Follow these steps after your eclipse repository is set to complete installation:
The ArcGIS Runtime SDK for Android allows easier integration into other developer environments without the support of a developer IDE plugin.
IntelliJ IDEA supports Android development much in the same way the ADT extends Eclipse for Android development. It offers excellent code assistance, integrated logcat, layout preview, and lint. Refer to the IntelliJ IDEA Web Help system to enable Android support. Once you have Android support enabled you can create a New Android Project.
Creating a global library allows you to add ArcGIS module dependency to any valid Android project.
Open your Android Manifest file by double-clicking on the AndroidManifest.xml file in your project directory. Add the following elements to your projects manifest under uses -sdk and above the application elements.
<uses-feature android:glEsVersion="0x00020000" android:required="true" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Now you are ready to start programming with the ArcGIS Runtime SDK for Android. A great place to start is the hello-world like tutorial, Add a map to your app.
The ArcGIS Runtime SDK for Android contains everything you need to develop ArcGIS Android apps. The contents of the SDK are provided below:
Version 10.2.2 is ready and waiting. Get it now.Download
Enhancements, known limitations, and migration information:At 10.2.2

App Widgets are mini apps that give users immediate access to important functions of an app.
We mostly use App Widgets to display important information about an app on a device’s Homescreen.
You can create your own app widgets. We’ll show you how.
Keep up with the fashion: Using Styles and Themes in your apps
Styles specify the look and feel of individual views, like text views and buttons.
Styles help you to:
Themes are simply Styles applied to an app or to individual activities.
Progress bars let the user know that the device is busy, for example, downloading a file. It can also show roughly how much longer the download will take.
Progress bars don’t always look the same on all devices.
We’ll show you how to customise your progress bars so that they look the same on all devices
Android touchscreen devices can sense when the user touches the screen. They can also record the movement of the user’s finger across the screen. These movements or strokes are also known as gestures.
You can store a collection of gestures in a file and then match the user’s gesture with those in the file.
Our tutorial app lets the user write their name on the screen using their finger. We then compare this gesture to our saved gestures and display the result in a text view.
Spinners display a list of selectable items.
When first displayed, the Spinner only shows the currently selected item. Touching the Spinner displays the full list of items that the user can choose from.
Our tutorial will show you how to use a Spinner to display a list of images that the user can choose from.
Our tutorial app creates a table containing text views, text fields and a button.
There is no XML layout file as we do everything programmatically.
A Toast message displays the input after the user has filled in the text fields and pressed the button.
Our tutorial app shows you how to use intents and intent filters in your apps.
Here’s a quick overview of what we’ll cover. We’ll show you how to:
Intents are messages that you can pass around between your app components. You can also send them to components in other apps. This enables you to create powerful applications where you can use other app’s components to perform tasks for you, such as playing music, sending email, and taking pictures.
Here are some of the things that you can do with intents:
The Android System also uses intents to signal changes such as low battery, incoming sms messages and phone calls. You can listen for these intent messages in your apps. You can also use intents to pass data.
You can use alarms to trigger events at any time even if your app is not running.

Addressing fluorogenic real-time qPCR inhibition using the novel custom Excel file system ‘FocusField2-6GallupqPCRSet-upTool-001’ to attain consistently high fidelity qPCR reactions
The purpose of this manuscript is to discuss fluorogenic real-time quantitative polymerase chain reaction (qPCR) inhibition and to introduce/define a novel Microsoft Excel-based file system which provides a way to detect and avoid inhibition, and enables investigators to consistently design dynamically-sound, truly LOG-linear qPCR reactions very quickly. The qPCR problems this invention solves are universal to all qPCR reactions, and it performs all necessary qPCR set-up calculations in about 52 seconds (using a pentium 4 processor) for up to seven qPCR targets and seventytwo samples at a time - calculations that commonly take capable investigators days to finish. We have named this custom Excel-based file system “FocusField2-6GallupqPCRSet-upTool-001” (FF2-6-001 qPCR set-up tool), and are in the process of transforming it into professional qPCR set-up software to be made available in 2007. The current prototype is already fully functional.

Perspectives on the Ethicality of AI-Enabled Recruiting and Selection
We start by reviewing the different perspectives from which AI-enabled recruiting and selection practices are investigated and ethical considerations are articulated.
The first group of papers assessed AI-powered recruiting practices from an ethics theory perspective. We identified three articles that applied a theoretical framework to AI recruiting and thereby provide a theoretical foundation for discussion: First, Simbeck (2019) referred to ethical frameworks from other disciplines, such as medicine, robotics, and AI, and applied them to the HR context. She proposed the transfer of key ethical concepts from the other fields that should be implemented when applying new AI technologies in HR analytics. She identified five key ethical principles: privacy and confidentiality, opportunity to opt out, institutional review, transparency, and respect for the dynamic nature of personal development.
Second, Yarger et al. (2020) referred to feminist thinking and methods, arguing that these should guide the design of AI hiring systems. Feminist approaches shed light on the extent to which algorithms may perpetuate disadvantage for historically marginalized groups when equity is not considered in their design. The authors presented a feminist design justice framework, which includes prompts that commit the architects of AI systems to engage with the design process in ways that support an ethic of equity.
Third, Rąb-Kettler and Lehnervp (2019) assessed AI recruiting from a humanistic perspective, in which people were placed at the center. The authors presented humanistic recruiting as an answer to the current technological developments. They argued that technology and automation can be implemented in a way that improves the experience for both the recruiters and candidates in the process. They concluded that both humanistic insight and sophisticated technology are important to adjust to today’s dynamic reality. Reviewing these three theoretical papers reveals that a detailed assessment of AI recruiting from the standpoint of one of the traditional ethics theories, such as utilitarianism or deontology, and a discussion of potential implications for the hiring practice has not been done yet.
The second and largest category of papers assumed a practice-oriented perspective and focused on implications that are most relevant for managers and corporations. Most of the identified papers fall into this group, the common aim of which was to raise practitioners’ awareness of the strengths and limitations of AI technologies implemented in the recruiting process. From an experience-based perspective, some papers (Florentine, 2016; Polli et al., 2019) underlined the problematic nature of traditional candidate assessment methods and presented the use of AI as a promising alternative; others (Bogen, 2019; Dattner et al., 2019) rather warned of AI-powered hiring practices by raising many yet-unanswered questions about their accuracy, as well as the ethical, legal and privacy implications that they introduce. Furthermore, some papers (Bîgu & Cernea, 2019; Chamorro-Premuzic et al., 2019; Giang, 2018; Mann & O’Neil, 2016) provided practical recommendations for managers on how to ethically implement AI for recruiting, aiming to guide organizations to take the right steps and make the right investments.
The third group of papers looked at AI recruiting from a legal viewpoint. The importance of employment decisions to individuals, as well as to broader society, has led to the design of an extensive legal framework to guide these decisions. For example, in the US, Title VII of the Civil Rights Act protects people from discrimination in any employment decision that would result in disparate treatment2 or disparate impact3. It also assigns liability and legal responsibility to employers to ensure that the tools used do not create such results. However, the identified literature (Bornstein, 2017; Kim, 2017; Kim & Scott, 2018) has claimed that, so far, the law of Title VII lags behind current scientific knowledge and modern business practices: Kim and Scott (2018) discussed that targeted advertising may result in unfair exclusions that are not covered by current law, Bornstein (2017) argued that current regulation does not go far enough and argued for liability when an employer acts with reckless disregard for the consequences of implicit bias in employment decisions, and Kim (2017) claimed that Title VII should be broadened, requiring employers to prove that the data created by their algorithms are accurate and do not discriminate, instead of requiring victims of discrimination to prove its occurrence. We further identified two qualitative analyses that embraced both a legal and a technical perspective, while investigating how bias mitigation methods are used in practice. While Raghavan et al. (2020) evaluated the efforts of AI software vendors to mitigate bias, focusing on the employment laws in the US, Sánchez-Monedero et al. (2020) analyzed three recruiting software vendors from the perspective of UK law, addressing concerns over both discrimination and data protection.
Moreover, we identified a group of articles that established ethical considerations on AI recruiting, while taking a technical perspective. Some papers (Chwastek, 2017; Köchling et al., 2020; Lin et al., 2020; Mujtaba & Mahapatra, 2019; Persson, 2016; Williams et al., 2018) explained emerging ethical problems by looking at the mechanisms of algorithms used. Others (Fernández-Martínez & Fernández, 2020; Pena et al., 2020; Vasconcelos et al., 2018) presented technical solutions to implement ethical principles into algorithmic code or design. For instance, Fernández-Martínez and Fernández (2020) found that there is a lack of regulation and a need for external and neutral auditing of the used AI technologies, and consequently, they presented a multi-agent software architecture to support auditing the recruiting processes. Furthermore, Vasconcelos et al. (2018) proposed a computational framework to mitigate discrimination and unfairness caused by bias in AI systems, inspired by epistemological principles. Lastly, one paper (Schumann et al., 2020) outlined several technical challenges for future research in algorithmic hiring that must be overcome to make it fairer and more intelligible.
Covering the field of descriptive ethics, the last category comprises several experimental studies (e.g., Langer et al., 2018; Lee, 2018; van Esch & Black, 2019), as well as a case study (van den Broek et al., 2019) that assessed people’s reactions to AI-powered recruiting practices. A couple of studies compared applicants’ fairness perceptions of AI-enabled interviews vs. traditional interviews with a human recruiter, revealing contrasting findings. Whereas a group of papers (Acikgoz et al., 2020; Lee, 2018; Newman et al., 2020) found that people perceived algorithm-driven decisions as less fair than human-made decisions, another group of papers (Langer et al., 2019a, 2019b, 2020; Suen et al., 2019) found no difference in fairness perception between decisions made by an AI or a human. Other studies (Gelles et al., 2018; Kaibel et al., 2019; Langer et al., 2018; van Esch & Black, 2019) examined different contextual and procedural factors, such as the level of information given to applicants regarding the used AI or the level of computer experience of applicants, and how they affect applicant reactions to the use of AI in hiring.
In summary, this overview attests to the overall heterogeneous perspectives applied to ethical considerations of AI-based recruiting and selection. It also reveals that only a few theoretical articles exist, and that extant literature is rather practitioner oriented.
Underlying Research Topic: AI Applications in the Recruiting and Selection Process
In the following, we provide an overview of AI applications used in the recruiting and selection process and addressed in the identified literature. An understanding of where AI-powered tools and practices are applied can assist in understanding where ethical opportunities and risks may arise. Our review shows that AI-enabled practices are relevant in each stage of the recruiting process and can include different types of AI and algorithms. Table 4 gives an overview of the different AI applications across the recruiting and selection stages: outreach, screening, assessment, and facilitation, which we further expand on below.
Several articles deal with AI technologies applied in the outreach stage, in which businesses try to detect talent and attract applicants. By leveraging algorithms for targeted communication across online platforms and social media or for the automated notification of job seekers, companies can expand their outreach to potential candidates (Bogen, 2019). Furthermore, AI bots are used to identify the pool of active and passive candidates (e.g., via LinkedIn) or to (re-)discover top talents in the pool of former candidates via their internal automated tracking system (ATS) (van Esch & Black, 2019). Sometimes, the challenge is not just finding the right candidates but persuading them to apply via appealing job descriptions. AI software vendors, such as Textio, use AI in the form of text-mining techniques to predict the attractiveness of a job listing based on the hiring outcomes of several millions of job posts. The software thereby scans the job ad for key phrases that will statistically impact its performance. Additionally, a tone meter can determine whether the overall tone of the writing is likely to attract more men or more women and make suggestions on how to improve the inclusiveness of the language used (Lewis, 2018; Yarger et al., 2020). This is how AI can help businesses de-bias the wording of job ads, making them gender neutral to attract a diverse pool of applicants, or customize them for a specific target group (Rąb-Kettler & Lehnervp, 2019).
Notably, most articles that deal with the ethicality of AI recruiting focus on the application of AI technology in an initial resume screening. AI systems are used to filter applicants to derive a shortlist and a ranking of the most promising candidates (Bornstein, 2017; Fernández-Martínez & Fernández, 2020; Vasconcelos et al., 2018). For many years, companies have used traditional algorithms to scan resumes for preselected key words or phrases; however, today’s AI technology goes beyond that. Now, chatbots and resume-parsing tools look for semantic matches and related terms determining a candidate’s qualification. Other tools go even further and use ML to make predictions about a candidate’s future job performance based on signals related to tenure or productivity, or the absence of signals related to tardiness or disciplinary action (Bogen, 2019). Based on the initial screening, algorithms can also suggest the best matching job opening for a given candidate (Rąb-Kettler & Lehnervp, 2019). These screening tools are considered highly efficient to streamline the process, especially for top employers who receive huge numbers of applications for each open position; however, concerns have been raised that highly qualified applicants may be overlooked (Persson, 2016).
Although screening algorithms are not new in practice, there has been a recent trend toward video-interview analysis in recruiting. In such structured video interviews, AI technology replaces a human interviewer and asks the candidate a short set of predetermined questions (Chamorro-Premuzic et al., 2016; Fernández-Martínez & Fernández, 2020). Moreover, the AI technology can not only evaluate the actual responses, but also make use of audio and facial recognition software to analyze additional factors such as the tone of voice, microfacial movements, and emotions to provide insights on certain personality traits and competencies (Köchling et al., 2020; Tambe et al., 2019; van Esch & Black, 2019).
Besides interviews, AI-powered skill tests, simulations, and neuroscience video games are used to assess further qualities, for example, applicants’ risk attitude, planning abilities, persistence or motivation. Thereby, target variables need not be predefined by the company (Giang, 2018; Polli et al., 2019; Raghavan et al., 2020), but ML algorithms can analyze the data of a company’s current top performers and derive which applicant characteristics and skills have been associated with better job performance (Tambe et al., 2019). In this way, data-driven assessment tools have changed talent signals and the criteria by which candidates are evaluated (Chamorro-Premuzic et al., 2016). For example, the software vendor Pymetrics uses ML and psychometric training data based on current top performers to predict an applicant’s fit for a specific role. To this end, first, the top-performing incumbent employees in that role play a series of online games, which are gamified assessments that measure numerous cognitive and social traits. The data collected from these games are then used to establish a “success profile” for the job at hand. Second, the candidates applying to the job play the same games, and the ML model predicts their likelihood of success in the role (Polli et al., 2019).
Other software vendors offer AI technologies that analyze a person’s digital records such as social media posts to construct a psychological profile of a candidate. Based on linguistic analyses of candidates’ Web activities, new technologies infer talent, personality, and other important individual differences and compare them against the culture of the hiring company (e.g., Chamorro-Premuzic et al., 2016, 2017; Vasconcelos et al., 2018).
Finally, AI is used to facilitate the recruiting process, taking over administrative tasks. For instance, AI tools address the problem of long online questionnaires for applicants via natural language processing (NLP) techniques. These are used to parse unstructured documents, such as candidates’ CVs, and extract relevant information to automatically complete a company’s application form (Chwastek, 2017). Furthermore, AI-powered assistants can be used to interact and communicate with candidates: They can guide candidates through the different steps of the recruitment process, from answering company and process-related questions to scheduling interviews (Rąb-Kettler & Lehnervp, 2019; van Esch & Black, 2019). Today, many companies also use programs to create offers automatically and have them signed electronically (Sánchez-Monedero et al., 2020).
Mapping of Ethical Considerations
This rise of new AI recruiting practices comes with new ethical quandaries for organizations and society. In what follows, we examine extant research literature and map the ethical considerations established. This mapping of ethical considerations can be understood as a summary of areas in which society may have ethical concerns about the use of AI, which is derived from extant literature. In mapping the ethical considerations, we distinguish between aspects that are, on the one hand, clearly characterized as morally good and thus as ethical opportunities, and on the other hand, aspects that are clearly characterized as morally bad and thus ethical risks. In addition, we outline issues that are controversially discussed in the literature and thus reflect ethical ambiguities that require deeper exploration. Table 5 provides a structured overview of this ethical evaluation.
Human and Algorithmic Bias
The most-discussed topic in extant literature on AI-enabled recruiting is the occurrence of bias. Although there is broad agreement that the practices currently in place are far from effective and unbiased (e.g., Chamorro-Premuzic & Akhtar, 2019; Persson, 2016; Polli, 2019), there are two differing ways, in which AI-powered tools may effect the scope of bias.
On the one hand, the use of AI may reduce human bias in different stages of the recruiting process and should therefore be considered a huge ethical opportunity (e.g., Chamorro-Premuzic & Akhtar, 2019; Savage & Bales, 2017). In the outreach stage, AI can address bias in the form of gendered language in job descriptions that dissuades certain candidates from applying for a role by creating inclusive job descriptions (Mann & O’Neil, 2016; Recruitment & Employment Confederation, 2020). In the screening procedure, subjectivity can be reduced by using algorithms that screen all applicants against the same criteria. AI is thereby able to assess the entire pipeline of candidates rather than forcing time-constrained humans to shrink the pool from the start, based on a biased process. Instead, AI can shrink the initial pipeline so a recruiter with a constrained capacity can manually handle it (Polli, 2019). Especially in the assessment stage, the use of AI technology can remove human bias from the process – or at least reduce it substantially. Human intuition can be very good and accurate, but it is nevertheless based on subjective value assessment (Persson, 2016). In contrast, via a digital interview or a video game assessment, AI automatically captures many data points of the applicants’ behavior, such as what they say, their language use or their body language, for an objective, data-driven assessment of personality (Jayaratne & Jayatilleke, 2020). Moreover, human bias (e.g., related to applicants’ physical appearance or other attributes) can be reduced, as AI can be taught to ignore people’s personal attributes and focus only on specified skills and behaviors (e.g., Bîgu & Cernea, 2019; Chamorro-Premuzic & Akhtar, 2019; Fernández-Martínez & Fernández, 2020). Lastly, human bias can be removed from the process, as the required skills and qualities for successful candidates are not determined by bias-prone intuitions from recruiters, but based on analyzing the characteristics of the company’s top performers (Lin et al., 2020).
On the other hand, AI-enabled recruiting also bears the risk of introducing different types of algorithmic bias (e.g., Bogen, 2019; Yarger et al., 2020). Yarger et al. (2020) cited three factors that may lead to biased decisions: bias in the model design principles, bias in the feature selection, and bias in the training data. A biased design, for example, may be manifested in online job platforms that make superficial predictions, not focusing on who will be successful in the role, but on who is most likely to click on the job ad. This can lead to a reinforcement of gender and racial stereotypes. A study found that targeted ads on Facebook for supermarket cashier positions were shown to an audience of 85% women, indicating that adverse impact can also occur in sourcing algorithms (Bogen, 2019). Moreover, critics are concerned that algorithms derived from information about current employees will unintentionally discriminate against underrepresented groups if existing employees are not proportionately representative of the broader application pool; this would constitute a case of biased training data (Kim, 2017). A known example from practice is the Amazon case, in which a hiring algorithm (in test mode) discriminated against women, assigning lower scores to resumes of women when ranking candidates. The algorithm was trained on data of current top performers, of which the majority were male. Thus, the algorithm penalized female attributes (e.g., Mujtaba & Mahapatra, 2019). In all these cases, algorithms can introduce bias and even magnify discrimination, affecting entire classes of individuals (Bogen, 2019; Tambe et al., 2019). The occurring discrimination may thereby be direct or indirect via proxy attributes. In the latter case, a protected group (e.g., a specific race) is discriminated against but based on legitimate grounds (e.g., a zip code) (Bîgu & Cernea, 2019; Fernández-Martínez & Fernández, 2020).
Proponents of AI recruiting tools admit that adverse impact can occur; however, they state that, compared with human biases, algorithmic biases are much easier to detect and remove (Florentine, 2016; Polli, 2019). Often, the fear of biased AI ignores the fact that the original source of algorithmic bias is the human behavior it is simulating (e.g., the biased data set used to train the algorithm). Thus, if people criticize what the AI is doing, they should criticize human behavior even more because AI is purely learning from humans (Polli, 2019).
Although there is an ongoing debate on the potential occurrence of algorithmic bias in AI recruiting, there is no ambiguity on the topic itself but general agreement that all kinds of bias and discrimination should be prevented. Therefore, AI recruiting can be classified as ethically preferable, as long as it seeks to reduce interpersonal bias in the process. However, current research suggests that the usage of AI can reduce bias but is never completely free of bias and carries the risk of algorithmic discrimination, even without bad intentions on the part of the programmers, which should be morally denounced. Thus, technical due diligence regarding algorithmic design and implementation is crucial to keep this risk low (see Sect. 3.4).
Effect on Workforce Diversity
A topic closely related to the occurrence of bias in the selection process is its impact on diversity: On the one hand, a reduction in human bias could lead to diversification of a company’s workforce (Chamorro-Premuzic & Akhtar, 2019; Recruitment & Employment Confederation, 2020). For example, the use of bias-neutral job posts created through AI may result in a more diverse pool of applicants (Lewis, 2018). Furthermore, the data-driven assessment leads to hiring of “nontraditional” candidates who might typically not make it through a hiring process (e.g., from a non-elite college, but with other strong skills). In this way, AI-enhanced recruiting tools can provide people from a wider range of socioeconomic backgrounds access to better jobs, expanding diversity, and socioeconomic inclusion (e.g., Florentine, 2016; Hipps, 2019). Moreover, case studies have shown that, for example, the aforementioned AI-powered video games by Pymetrics have a clear positive impact on companies’ gender diversity (Polli et al., 2019).
On the other hand, a systematic bias through AI could result in more homogeneity in organizations (Chamorro-Premuzic et al., 2019; Vasconcelos et al., 2018; Yarger et al., 2020). As a single decision-making algorithm, which selects candidates based on certain profiles and traits, replaces several human decision makers with potentially differing views, this may also imply a loss in diversity (Vasconcelos et al., 2018; van den Broek et al., 2019; Bîgu & Cernea, 2019). Further, Fernández-Martínez and Fernández (2020) warned that the use of AI leads to increased racial bias: Given that emotional recognition software may not consider different intonations in different languages or that emotions are differently expressed in different cultures, it may systematically disadvantage specific races or ethnic groups, which could lead to a decrease in workforce diversity.
This research question about the influence of AI on diversity has also been discussed in general diversity scholarship. Ozkazanc-Pan (2019) outlined how advanced technological shifts impact diversity scholarship, underlining the importance of bias, ethical considerations and digital inequalities in this context. She also thereby referred to the recruiting context and, for example, pointed out how the creation of employee profiles that are based on behavioral preferences, when not implemented carefully, can lead to HR managers hiring the same groups over and over again, which can hinder a company’s diversity efforts.
Overall, there is no clear understanding of what impact the use of AI has on the diversity of corporate workforces, but the topic is controversially discussed in extant literature. Therefore, relevant empirical studies would be desirable in future. It must be noted that diversity is related to, but different from, non-discrimination, and more textured efforts are needed to explore the balance between diversity and non-discrimination (Schumann et al., 2020). An interesting question in this context may be whether it is ethical to promote diversity even if it discriminates against historically advantaged groups.
Privacy and Informed Consent
Another ethical consideration raised is the concept of privacy and informed consent. In this context, businesses must account for government regulations, which differ across countries. The European General Data Protection Regulation (GDPR), which came into effect in May 2018, is one of the strictest. It aims to protect EU citizens’ rights by regulating how to collect, store, and process personal data and requires informed consent for any personal data processing (i.e., applicants must have the opportunity to agree or not agree to the use of their data). However, the informed consent requirement is not yet well implemented in the big-data and AI-regulation context, rendering the protection of personal privacy an ethical challenge (Oswald et al., 2020). An ethical dilemma emerges at this point as applicants in the job market generally hold less power than employers. Even if applicants are informed enough to consent to the process, they may not be able to opt out without being disadvantaged in the process. It is therefore difficult to give explicit consent in the context of hiring anyhow (Sánchez-Monedero et al., 2020).
Moreover, there is active debate about the extent to which it is ethically appropriate to use social media information for personnel selection purposes (Chamorro-Premuzic et al., 2016; Oswald et al., 2020). Legally, social media content is public data, but it is questionable whether it is ethical to mine social media data for hiring purposes when users generally use those platforms for other purposes and may not have provided their consent for data analysis (Dattner et al., 2019; Tambe et al., 2019). Also, the extent to which social media posts are a valid and reliable indicator of personality or job performance is doubtful (Vasconcelos et al., 2018; Yarger et al., 2020). Chamorro-Premuzic et al. (2016) argued that it is naive to expect online profiles to be more authentic than resumes, but they can offer a wider set of behavioral samples. Prior empirical findings on the validity of social media data have been mixed (Ryan & Derous, 2019). Whereas some studies found connections to job performance (e.g., Kluemper et al., 2012), van Iddekinge et al. (2016) showed that recruiter ratings of applicants’ Facebook information were unrelated to their subsequent job performance and lead to subgroup differences, by favoring female and Caucasian applicants. This discussion on the use of social media information in the hiring context is not new and only connected to the use of AI. A study in Sweden showed that at least half of the interviewed recruiters had scanned applicant social media profiles themselves at some point before hiring (Persson, 2016). However, the new AI techniques make the analysis of social media profiles easier and even more tempting.
There are further AI-enabled ways to discern applicants’ private information indirectly. For example, image and voice recognition techniques can predict applicants’ sexual orientation, race, and age, as well as their physical attractiveness (Chamorro-Premuzic et al., 2016; Dattner et al., 2019). Other prediction algorithms may forecast who is more likely to become pregnant (Oswald et al., 2020; Simbeck, 2019). This greater access to candidates’ personal attributes can not only increase the risk of misuse and intentional discrimination (Fernández-Martínez & Fernández, 2020), but also might further an information and power asymmetry between candidates and potential employers, leaving applicants with less room to negotiate (Sánchez-Monedero et al., 2020).
Overall, extant research has agreed that AI recruiting practices constitute a potential privacy loss for applicants attended by a greater power imbalance between applicants and employers; this poses an ethical risk. In addition, the use of more personal data, which may lead to more accurate predictions, is controversial (see also the next section). Thus, it is currently an unresolved normative question the extent to which a company may legally and ethically collect, store, and use personal data from applicants, such as the information available on social media platforms (Lin et al., 2020).
Consistency, Accuracy and Validity
There is broad agreement in extant literature that AI enables companies to make decisions more consistently across candidates and time (van den Broek et al., 2019). Whereas traditional assessment techniques such as analogue interviews are difficult to standardize, AI-based practices allow firms to put all applicants through exactly the same experience, resulting in an increase in the consistency of candidate assessment (Chamorro-Premuzic, 2019).
However, the accuracy and validity of the new AI assessment methods are controversially discussed. Today, employers do not necessarily know exactly which characteristics make an applicant a good fit for a given role. Studies have shown a very small correlation between a person’s academic grades and their professional performance; still, many companies make above average grades a requirement for application. In contrast, some articles (e.g., Chamorro-Premuzic et al., 2019; Polli et al., 2019) argued that the new AI technologies have the potential to make the selection process more accurate as hiring algorithms predict a candidate’s work-related behavior and performance potential based on the data of current top performers. AI may thereby outperform human inferences of personality in accuracy because it can process a much larger range of behavioral signals (Chamorro-Premuzic & Akhtar, 2019; Chamorro-Premuzic et al., 2016; Polli et al., 2019). In this way, the use of AI improves both the possibilities of “what” and “how” skills and abilities are measured (Ryan & Derous, 2019).
One article pointed to the accuracy–fairness trade-off in recruiting decisions and stated that AI technologies constitute the opportunity to overcome it (Chamorro-Premuzic et al., 2019). Historically, research has shown that traditional cognitive ability tests have led to discrimination of underrepresented groups, such as candidates with a lower socioeconomic status. Thus, to increase diversity and create an inclusive culture, companies have often de-emphasized cognitive tests in hiring (Chamorro-Premuzic et al., 2019). However, AI may overcome this fairness–accuracy trade-off by deploying more dynamic and personalized scoring algorithms that can optimize for both (Chamorro-Premuzic et al., 2019; Raghavan et al., 2020).
Nevertheless, critics have raised concerns about the technical robustness and validity of AI-powered assessment methods. First, many of the newly offered AI tools have emerged as technological innovations, rather than from scientifically derived methods or research programs. Although there has been broad psychological research on the validity of traditional methods for candidate assessment, such as job interviews, assessment centers, or cognitive ability tests, the newly emerging AI tools have not been sufficiently scientifically validated, with regard to the underlying criteria for the prediction of job performance (Chamorro-Premuzic et al., 2016; Dattner et al., 2019; Raghavan et al., 2020). This means that firms may reject candidates based on unexplained correlations and make decisions based on factors with no clear causal connection to job performance (Cappelli, 2019; Kim, 2017). When AI links the tone of voice to differences in job performance, it raises the additional ethical question of whether it is appropriate to screen out people based on physically determined and rather unchangeable attributes (Dattner et al., 2019). Moreover, the indirect measurement of personality itself is still an open and discussed topic (De Cuyper et al., 2017).
Second, technical implementation bears some risks. For example, Tambe et al. (2019) argued that good employees are hard to measure, as it is difficult to disentangle individual from group performance. Further, introducing technological context, such as video games or avatar interviewers, to the recruiting process may add noisy variance to applicants’ performance and, thus, measurement error (Ryan & Derous, 2019). Therefore, a constant re-validation and control of the algorithmic tools is crucial. However, AI software vendors often do not publicly communicate whether or how they conduct validation studies on their models (Raghavan et al., 2020).
Third, Fernández-Martínez and Fernández (2020) brought up the risk that AI might not work equally for many people, undermining its accuracy. Along these lines, several studies (Buolamwini & Gebru, 2018; Raji & Buolamwini, 2019; Rhue, 2018) have shown that facial recognition software performs rather poorly, suffering from disparities in error rates across gender and race. Finally, Tambe et al. (2019) reported that AI recruiting faces the challenge of making trade-off decisions between accuracy and other ethical principles. For example, the authors stated that more “complicated” algorithms are more accurate, but they are also harder to explain, resulting in a trade-off between accuracy and explainability (we discuss the latter in the next paragraph).
These concerns about potential lack of validity and accuracy result in the question of whether it is ethical to use these new AI tools compared with more longstanding psychometric assessments that have been scientifically derived and validated. Which features are predictive, which are not, and which are protected? In particular, the selection of the features that define a good candidate is an ethically laden decision, about which current literature is ambivalent and further scientific validation is necessary (Schumann et al., 2020).
Transparency and Explainability
Another ethical opportunity mentioned in extant literature is the ability to establish transparency by providing applicants with updates and feedback throughout the process and in a timely fashion (e.g., via chatbots and AI technology), which can be considered one element of fair treatment (van Esch & Black, 2019). Often, firms fall short of providing relevant information in a timely manner, or they provide no information other than confirmation that a candidate’s application has been received. This can be very frustrating for candidates. However, next to progress updates, AI further enables firms to generate detailed feedback and give millions of job applicants data-driven insights on their strengths and development needs (Dattner et al., 2019).
However, the use of AI can also lead to a lack of transparency toward applicants, when the use of AI and automated systems is not proactively communicated to candidates (Sánchez-Monedero et al., 2020). Moreover, the predictive and decision-making processes of algorithms are often opaque, even for the programmers themselves. When algorithms take millions of data points for the assessment of a candidate, it becomes difficult to provide a qualitative explanation of which attributes are driving the decisions (Raghavan et al., 2020; Simbeck, 2019). This is ethically critical in the personnel selection context, due to its high relevance for people’s lives, and because this kind of black-box system may remain unchallenged, thereby obscuring discrimination (e.g., Tambe et al., 2019; Vasconcelos et al., 2018). Therefore, the GDPR also warrants a “right to explanation,” by which people can ask for explanations about (algorithmic) decisions made about them (Pena et al., 2020).
Overall, the ethicality of AI recruiting depends highly on the mode in which it is implemented and used. On the one hand, it offers a huge ethical opportunity in the form of timely feedback for applicants; on the other hand, it bears the ethical risk of omitting transparency and explainability. Extant literature agrees that companies and recruiters should not rely on information produced by a black-box algorithm they do not fully understand. This is an open technical challenge to solve: building algorithms and AI applications that lead to explainable results (Schumann et al., 2020).
Closely related to the issue of explainability is the topic of accountability in the hiring decision-making context. When automated AI technologies are used for decision-making, a question arises of whose job it is to adhere to ethical norms and labor laws, and who can be held responsible and accountable for the decisions made: the data scientists, the hiring managers or the company as a whole? This question becomes even more difficult when firms are not developing the AI themselves, but instead buying the technology from third-party vendors who want to protect their intellectual property and may not be willing to grant full transparency into the algorithms used (Sánchez-Monedero et al., 2020; Tambe et al., 2019). Lin et al. (2020) outlined that in the recruiting process, agents with different roles in the collective decision-making process can have a collective responsibility (i.e., each agent fulfills his or her role and shares a collective responsibility). Thus, when a recruiter makes a morally wrong decision based on a problematic recommendation by an AI, which in turn results from the negligence of a software engineer, both the recruiter and the engineer are collectively responsible and accountable for the wrong decision. Building on this discussion, Bornstein (2017) and Kim (2017) claimed that current regulation should be broadened, making companies that apply AI recruiting practices fully liable for any occurrence of discrimination or implicit bias in employment decisions.
It is clear that the AI itself cannot be held accountable; it should be a human agent who is ultimately responsible for the decision made when selecting an employee (Lin et al., 2020). However, the use of AI results in an obfuscation of responsibilities and accountabilities, which represents an ethical risk and must be clarified.
Human Oversight and Autonomy
The extent to which AI is integrated into the decision-making process varies across businesses. Some papers (Fernández-Martínez & Fernández, 2020; Yarger et al., 2020) have reported that increasingly more tasks are taken over by algorithms, though firms still rely on human recruiters to make the final decision. However, other papers (e.g., Lee, 2018; Vasconcelos et al., 2018) have stated that AI has already taken over the automated decision-making process, forwarding or rejecting candidates. This raises the question of whether it is ethical to base hiring decisions solely on algorithms and without human intervention. Sánchez-Monedero et al. (2020) even raised the point of whether, due to the new GDPR regulation, it is in fact illegal to use a solely automated hiring system in the EU, because the GDPR grants people the right to a “human in the loop.” Overall, extant literature agrees that the loss of human oversight should be avoided, but human involvement in the training, validation, and deployment process should be maintained.
Additionally, Lin et al. (2020) raised the question of whether the usage of AI effects human autonomy. When AI applications and analyses shape human decisions by interfering with deliberation processes, the violation of human autonomy can become a serious ethical concern. The authors called this “AI paternalism” (p. 16). However, this topic is not further discussed in the identified literature. Thus, questions regarding how AI impacts the autonomy and dignity of candidates remain open.
Efficiency Gains and Effects on Internal Organization
In the first place, AI-advanced selection tools are attractive for organizations, as they make hiring more cost- and time-efficient (e.g., Lee, 2018; van Esch & Black, 2019). With the help of AI, employers have a greater ability to quickly shortlist candidates with high potential and streamline the selection process (Hipps, 2019; Persson, 2016; Savage & Bales, 2017). For example, AI technology provides firms with the ability to initially screen and process hundreds of applications in a short time frame (Persson, 2016). Moreover, AI-powered video interviews increase efficiency by reducing selection process time as well as candidate time and travel distances (Fernández-Martínez & Fernández, 2020).
However, the use of AI has further effects on the internal organization. The enhancement of recruiters’ jobs is thereby considered an ethical opportunity of AI-enabled recruiting practices (Rąb-Kettler & Lehnervp, 2019; van Esch & Black, 2019). Daily, recruiters are confronted with numerous repetitive tasks, such as screening resumes, scheduling interviews and conducting similar conversations. When these tasks are taken over by AI, it results in a more meaningful job, as recruiters can undertake activities of higher value for the company. For instance, they can adapt better engagement techniques to ensure that a leading candidate accepts a job offer (Hipps, 2019; van Esch & Black, 2019) and can better focus on the individual candidates, stepping from a pure head hunter role into a career guide role (Rąb-Kettler & Lehnervp, 2019). Although the identified articles evaluated the effects of AI recruiting on the internal organizational members very positively, they must be studied in greater detail. For example, it needs to be tested whether a greater volume of candidates may prevent any gains in work time for recruiters (Ryan & Derous, 2019). Further, potential job losses of recruiters are not yet part of the discussion.
Although the research on applicant reactions to technology-powered recruiting processes has increased in recent years (see Woods et al., 2020 for a review on applicant reactions to digital selection procedures), there is limited understanding of how people perceive AI recruiting and contrasting findings exist. Several studies of applicant reactions to AI interviews provide some cause for concern as they reveal that applicants perceived AI interviews as less fair and less favorable than face-to-face interviews with humans (Acikgoz et al., 2020; Lee, 2018; Newman et al., 2020). For example, Lee (2018) found that participants believe that AI lacks certain human skills that are required in the recruiting context: It lacks human intuition, makes judgments based on keywords, ignores qualities that are hard to quantify and is not able to make exceptions. Furthermore, some participants felt that using algorithms and machines to assess humans is demeaning and dehumanizing (Lee, 2018). In contrast to those findings, another group of papers (Langer et al., 2019a, 2019b, 2020; Suen et al., 2019) found no differences in perceived fairness between interviews with an AI and interviews with a human among job applicants, although most of them exhibited lower favorability to AI interviews.
Other studies (Gelles et al., 2018; Kaibel et al., 2019; Langer et al., 2018; van Esch & Black, 2019) examined the effect of different contextual factors on applicant reactions to the use of AI in hiring. For instance, Langer et al. (2018) found that applicants with a computer science background did not perceive AI recruiting differently from non-computer science applicants. Another study by Kaibel et al. (2019) examined the moderating effect of applicants’ discrimination experience and uniqueness. They found that applicants who have experienced discrimination before perceive selection processes as fairer when an algorithm instead of a human makes the decision, whereas the negative effect of AI-based selection decisions on organizational attractiveness was stronger for individuals with a high sense of personal uniqueness. Underlining the relevance of perceived fairness, a study (van Esch & Black, 2019) found that the more job candidates perceive the AI-enabled recruiting system as providing fair treatment, the likelier they are to engage in and complete the recruiting process.
In a case study, van den Broek et al. (2019) found that different stakeholder groups may hold different and clashing notions of fairness, which may even be reconsidered during the implementation of AI recruiting in practice. For example, although AI tools are introduced to make the process fairer and decisions consistent across the company, it was observed that some recruiters did not use the algorithmic results consistently, but made exceptions, which they perceived as fairer.
Overall, there is no clear answer to the question of how AI recruiting is perceived. What is perceived as fair in one context may be judged differently in another. Although we found several studies examining the fairness perceptions of applicants, the perspective of current employees and HR managers on AI recruiting tends to be neglected. This leaves open the question of the extent to which HR managers trust and accept AI recruiting.
Approaches to Mitigate Ethical Risks
As shown in the previous section, the new AI technologies pose new challenges to regulation and governments, especially as they are being applied in recruiting. Some approaches to mitigating the emerging ethical risks in the AI recruiting context are discussed in extant literature.
In the identified literature, it has been broadly claimed that more governmental regulation is needed to respond to the new developments in hiring: Whereas Kim (2017) argued for a legal response to what she called classification bias, Fernández-Martínez and Fernández (2020) called for governments to track selection processes and check for any infringement of fundamental employment laws or human rights. In their recent analysis, Raghavan et al. (2020) found that currently, vendors’ practices in bias mitigation are heterogeneous. This suggests that evolving industry norms are sensitive to bias concerns but lack clear guidance on how to respond. However, as current regulation leaves room for unethical behavior of firms, today, employers need to think beyond governmental law when developing and using predictive hiring tools (Bogen, 2019).
Extant literature refers to various organizational standards that firms may and should implement to ensure ethical use of AI in recruiting. First, it is suggested that companies applying AI tools in the personnel selection process comply with privacy laws just as they would in traditional hiring. On the one hand, this means that organizations should fully protect and keep safe all sensitive data. On the other hand, recruiters should not use or predict any private or sensitive candidate information in the recruiting process. In addition, firms should proactively and fully brief candidates that their data will be analyzed by AI systems and obtain their consent (e.g., Chamorro-Premuzic & Akhtar, 2019; Simbeck, 2019). Second, firms should proactively and explicitly provide meaningful information on the hiring decision-making process, including information about the algorithmic techniques and data sets used, to ensure transparency and craft effective policy (Köchling et al., 2020; Raghavan et al., 2020; Sánchez-Monedero et al., 2020). Additionally, it should be always transparent to applicants whether they are communicating with another human or with AI (Simbeck, 2019). Third, several papers (e.g., Chamorro-Premuzic & Akhtar, 2019; Köchling et al., 2020) also suggested human oversight on AI as a standard for organizations. The authors encouraged a human review, in which experienced recruiters oversee the selection and evaluation made by AI. They argued that decisions should be made by an algorithm-informed human, rather than by an algorithm alone. Fourth, to further ensure and audit the implementation of these ethical standards, various authors have referred to compliance instruments companies should establish, such as an AI ethics board with an oversight function, consisting of representatives of relevant stakeholders who debate the data and ethical dimensions of AI algorithms and agree on boundaries for AI technology in the company (Simbeck, 2019; Tambe et al., 2019). In addition, Tambe et al. (2019) recommended specifying a code of ethics for AI-related initiatives within the company. Lastly, authors have encouraged diverse data scientist teams in organizations to foster inclusion and equity in AI (Giang, 2018; Yarger et al., 2020). In particular, in the ML algorithm development process, diverse voices across gender and race must be present to raise questions and check implicit assumptions.
Technical Due Diligence
Next to approaches on the governmental and organizational level, the identified literature also discusses technical methods to ensure ethical application of AI tools in recruiting. First, authors mentioned the data literacy of programmers, as well as the knowledge of hiring managers on how to use the AI solutions as a first prerequisite. Given that any data concerns can have a life-changing impact on applicants, companies need to have adequate levels of data and statistical skills to assure the accuracy and validity of the developed algorithms (Fernández-Martínez & Fernández, 2020; Lewis, 2018; Simbeck, 2019). Second, if companies do not develop the algorithms in-house, but buy more innovative skill tests or games from external vendors, practitioners are strongly encouraged to refer to professional test standards and obtain critical information about the tools: for example, evidence that informs psychometric reliability, criterion-related validity and bias implications (Oswald et al., 2020).
Third, the ethicality of the AI tool design, which should include bias mitigation techniques, plays a crucial role. For instance, some AI software vendors remove any wording or phrases that can unconsciously predict the gender of a candidate from CVs to circumvent unconscious bias and improve equity (e.g., Lin et al., 2020; Yarger et al., 2020). A different approach suggested by Williams et al. (2018) is to proactively gather and use social category data to illuminate and combat discriminatory practices. The authors argued that only when data are labeled with social categories can data scientists detect, understand, or remediate patterns of discrimination. Furthermore, open-source tools and technical frameworks for data scientists (e.g., IBM’s “AI Fairness 360”) can facilitate systematic bias checks and assist developers in embedding fairness in their algorithms (see Mujtaba & Mahapatra, 2019 for an overview of open-source toolkits). However, Sánchez-Monedero et al. (2020) pointed to the computational limitations of bias mitigation techniques and further argued that most bias mitigation systems aim at meeting the constraints of US law, which makes them not directly applicable in EU markets. In the context of ethical AI, Polli (2019) further referred to the movement among AI practitioners to develop a set of design principles for making AI ethical and fair (i.e., beneficial to everyone). She thereby emphasized the key principle according to which AI should be designed so that it can be easily audited. Rather than just assuming that algorithms yield accurate results, employers must regularly check the technology used for discrimination, as well as data errors and biases (e.g., Fernández-Martínez & Fernández, 2020; Hipps, 2019; Polli, 2019). Efforts must be made to constantly improve the robustness of any AI tool and, thus, proactive auditing methods should be implemented (Köchling et al., 2020). For example, outside professionals can be hired to build an internal auditing team to look at the AI decisions and audit key algorithms (Giang, 2018; Mann & O’Neil, 2016). They can carry out random spot checks on algorithmic recommendations, investigating in detail which candidates the algorithm has been selecting and why. To this end, Fernández-Martínez and Fernández (2020) developed an automated multi-agent software architecture to support auditing the recruiting process.
Lastly, companies need to be able to explain why a candidate has been selected and the causality regarding which specific attributes can be associated with their success in a role (Chamorro-Premuzic et al., 2019; Lewis, 2018). Thus, employers should not rely on black-box models, but develop AI applications that are interpretable (Lin et al., 2020). Transparency on algorithmic assumptions and models (e.g., in the form of explainability reports) is key in the mitigation of bias and when addressing trade-off decisions data scientists have to make (e.g., Mujtaba & Mahapatra, 2019; Tambe et al., 2019).
Awareness Among Employees
AI plays a critical role in technology to attack the diversity problem. It is therefore crucial that companies invest not only in AI technology, but also in people who are aware of both the opportunities and the risks that attend AI-powered recruiting practices (Chamorro-Premuzic et al., 2019). The awareness and sensibility of recruiters and data scientists about the potential bias and shortcomings of their algorithms is key to address the accompanying ethical challenges (Simbeck, 2019). When regulation is not enough to guide human behavior, ethical thinking and awareness of conscious use of predictive AI tools must be further promoted beyond regulation (Persson, 2016).

Deep Scene Perception without Labeled Data
This talk will present the recent research work carried out at CVLab-University of Bologna in the field of deep learning for scene perception. The leitmotif behind our work concerns avoiding reliance on supervision from labeled data, which, indeed, I am lead to posit not to even exist when it comes to train models aimed at key perception tasks like depth prediction.
Firstly, I will address depth estimation from both stereo as well as monocular views. Here, the main contribution of our research concerns deploying self-supervision to pursue domain adaptation of deep CNNs pre-trained on computer generated imagery. This, indeed, lead us to the development of the first-ever on-line adaptive stereo network, i.e. a CNN that deploys an efficient continual learning paradigm to keep-up with domain changes in real-time.
As for depth-from-mono, based on the intuition that effective monocular depth cues arise from semantic knowledge, I will show how joint learning of depth and per-pixel class labels can ameliorate depth prediction significantly.
I will dwell further into cross-task learning by presenting our novel AT/DT framework, which allows for transferring learned representations across different task and domains, so to, e.g., enable predicting depths in a target domain by leveraging on sematic labels only (or vice-versa).
I will then present our latest results dealing with the first CNN architecture for comprehensive scene perception from monocular videos: ΩNet (CVPR 2020) can predict depth, semantic labels, optical flow, per-pixel motion probabilities and motion mask based on a novel training protocol relying on self-supervision and knowledge distillation.
Finally, I will address perception from point clouds and present our rotation-equivariant local 3D descriptor based on Spherical CNNs and learned end-to-end from raw data without any explicit supervision. Peculiarly, this proposal is conducive to extraction of a canonical orientation from the learned rotation-equivariant representation so as to allow for rotation-invariant descriptor matching.
To conclude the talk, I will briefly show some unpublished results from an on-going project carried out in cooperation with a major company.

Firenado is a python web framework based on Tornado web framework/server.
Firenado is a Python web framework that encapsulates and extends Tornado organizing the application in components also adding a server side session layer, yaml based configuration files as other features common that will help developers building web applications and services.
pip install firenado
Creating and running a new application:
> firenado project init helloworld > helloworld > firenado app run
By default an application will be created with a redis based session and a redis data source defied and linked to the session.
Firenado don’t install redispy so it is necessary to either install it or turn the session as file based. You can disable the session engine too.
To change the session type to file go to helloworld/conf/firenado.yml and change the session definition to:
# Session types could be: # file or redis. session: type: file enabled: true # Redis session handler configuration #data: # source: session # File session handler related configuration path: /tmp
If your helloworld project isn’t on the python path just go helloworld/conf/firenado.yml and configure the application settings:
app: component: helloworld data: sources: # Set here references from sources defined on data.sources - session pythonpath: .. port: 8888

Unformatted text preview: for a
set of parameters that cause the inputs to model the outputs. Function learning attempts to
nd the best parameter vector v; alignment attempts to nd the best transformation T . As
we did for function learning, we can draw an analogy with sample entropy. The log likelihood
of T is proportional to the conditional entropy of the image given the model,
log`T = , N havT X j uX ; T; ; q; F :
a 4.14 This is not the EMMA estimate of entropy, but the conditional entropy of v under the
assumption that v is conditionally Gaussian. For the problems described in Section 3.1 it
was possible to show that entropy optimization led to maximum mutual information solutions.
For this problem however, we cannot claim that maximizing log likelihood is equivalent to
maximizing the mutual information between v and u. The mutual information I vT X ; uX = hvT X , hvT X j uX ; T; ; q; F ; 4.15 includes both a conditioned and unconditioned entropy. For some types of transformations
hvT X may change as T is varied. In these cases minimizing conditional entropy is not
equivalent to maximizing mutual information. One must also maximize the unconditioned
entropy. In our simple example, where only translation is varied and the signals are periodic,
unconditioned entropy does not change as T is varied.
Returning to the rst synthetic example, we can plot C T from 4.12 versus translation. Figure 4.3 graphs C T for the two signals from Figure 4.1 we have assumed periodic
boundary conditions on the signals. We can see that the cost has a very strong minimum at
the true translation of 0 pixels.

Correlation works very well at matching together u and v when the imaging model and
exogenous parameters are known. In many cases however we may be faced with a situation
where F and q are unknown. In some cases alignment problems can still be solved by
assuming that the imaging function is the identity function. This assumption is not e ective
when aligning the non-monotonically related signals shown in Figure 4.2. Figure 4.4 graphs
C T versus translation for these two signals. Notice that each of the actual minima are at
In general C T cannot be used to align signals related by an unknown non-linear transformations. C T can however be generalized to work with signals that have been transformed
linearly. Rather than minimize the squared di erence between signals, we can instead minimize the squared di erence between signals that have been normalized. A normalized signal

be computed directly as one minus the Normalized correlation between the signals u and v.
Normalized cost is de ned as:
, u E
NC T = 1 , Ea uX vT X EavTXX a vT X :

As a shorthand we have abbreviated sums over the coordinates x as expectations and variances.
Normalized cost can be used on signals like the ones shown in Figure 4.5 F u = 3u , 2.
A plot of NC T versus translation is identical to Figure 4.3. In some cases, normalized cost
can be applied to signals transformed by non-linear monotonic functions. Note however that
the two signals shown in Figure 4.2 are related by a non-monotonic function and cannot be
accommodated in this way. In these examples translation does not e ect the mean or the
standard deviation of the signals. As a result, normalized cost will not produce a convincing
minimum where cost alone does not.

Why to write kfemate?
for which in mexico there is no software wherefrom choosing, and realizing searches in the web many leave to me that to wish, that's why I decided to write kfemate, enjoy it!
Why Open Source?
because I believe that there are many persons who want something rapid and that it could be modified to his needs, I did not write kfemate with all the options for the whole world, only for me, that's why it is Open Source.

Speaker: Augusto Marques Ferreira Silva is an Associate Professor in the Department of Electronics, Telecommunications, and Informatics and a member of the Institute of Electronics and Informatics Engineering of Aveiro – IEETA. He is also the Director of the Master’s program in Medical Image Technologies. His preferred research area is Medical Image Processing with a focus on Machine Learning methods.
Abstract: In an era where data-driven decision-making has become central to healthcare, machine learning (ML) holds great promise. This presentation aims to promote discussion on the often overlooked but critical aspect of ML in healthcare: the pitfalls and challenges.
Key themes will include data quality and bias, interpretability, generalization, and ethical considerations. We’ll discuss how the unique characteristics of healthcare data, such as class imbalance and noisy labels, can skew model performance and decision-making.
Furthermore, we will emphasize the importance of interpretability and transparency in healthcare ML models. The ability to explain and understand model predictions is paramount when lives are at stake.
Generalization, or the ability of models to perform well on unseen data, is another critical challenge in healthcare. We will discuss strategies to mitigate overfitting and ensure that ML models perform reliably across diverse patient populations.
The role of latest trends such as generative ML will be addressed with some practical examples.
Ethical considerations, such as patient privacy, consent, and fairness, will be central to our discussion. We will address the ethical dilemmas that arise when deploying ML in healthcare and offer guidance on responsible AI implementation.

You still need to mount that printer onto your computer then share the printer via lpd.

Otherwise, Windows does not display the driver in the list displayed in the printer's properties when assigning the driver. Understand with lpd running on your linux box, there is no processing that happens on the linux box.

Tutorial for the pipe() system call. In this video, we illustrate the basics of pipe() and how you can use it to allow multiple processes or programs to communicate with each other. Pipe() takes in an int array of size two, and the indices of this array will act as each end of our pipe. It is now possible to disconnect stdin and stdout from the terminal and reconnect (stdin and stdout) with the ends of the pipe to allow communications between different processes.

Emulator Issues #7098
GBA Connectivity Master Issue
For its time, The GameCube has a very unique feature of using Link Cables to connect its handheld counterpart, The Gameboy Advance, for additional game features. This feature was used mostly for additional features, transferring data and additional gameplay modes, and most of all, selling GBAs and link cables.
Usage and information:
For example, Pokemon Colosseum and XD both allowed you to battle in full 3D between two players that had GBAs. The screens kept all your battle options secret from your opponent, likely because they were too lazy to do what Pokemon Stadium 1 and 2 already perfected. Those two games and Pokemon Box also allowed you to transfer Pokemon into your Ruby, Sapphire and Emerald Pokemon games.
Wind Waker and others has the Tingle Tuner, connecting a GBA gets you extra options that enhance the main gameplay mode.
A few games used the GBA connectivity as their main hook. Four Swords Adventures and Final Fantasy: Crystal Chronicles are well known multiplayer games that use the GBAs as controllers and their extra screens for menus, notifications and even gameplay. Pacman VS and the aforementioned Pokemon Box go even further, using GBA connectivity as the sole way to play the games.
Due to latency concerns, it's likely impossible to connect a real GBA to dolphin. Even if we could, it'd require custom hardware for connecting and cause all kinds of headaches. The solution to that, of course, is to use a GBA emulator. As of this post, VBA-M can connect to dolphin, and a couple of the games that use these features work relatively well, and a few more at least connect.
Unfortunately, there are far more games with problems and even more that don't seem to work at all. To complicate matters further, because two emulators are involved, problems could be on both sides of the connection, VBA-M could have problems, Dolphin could have problems... or both!
Speed issues, in order for this issue to be closed, both emulators must run at full speed (or at least theoretically if on a fast enough computer.) Some games as of this posting run < 1 fps when set to default frame limiters. Messing around may improve, but never totally fix. Another example is if it requires one emulator to run far above full speed for the other to reach full speed.
Disconnection issues. It is not acceptable for the GBA Emulator to lose connection to dolphin.
Failure to connect issues. The GBA emulator or Dolphin lock up upon connecting to one another.
Further Information and Data
A total list of games that use the GBA Link Cable can be found here: https://wiki.dolphin-emu.org/index.php?title=Category:Game_Boy_Advance_%28Input_supported%29
A guide to connecting VBA-M to Dolphin (Edited from the Working Guide on the Wiki)
Game Boy connection support can be supported via joybus emulation. Such requires VBA-M (r947 or newer, latest should work) and a dump of GBA BIOS.
1: Launch Dolphin and start the game you intending to play. Get to the point at which it prompts you to connect the GBA; or if it just intends it to be connected all along, just keep the game running.
2: In Dolphin, go to Config => GameCube and change the controller ports to GBA;
Launch VBA-M, go to Options => Emulator and uncheck "Pause When Inactive". Then, go to Options => Link => Joybus options, mark "Enable Joybus Connection" and use default settings (127.0.0.1)
3: After enabling joybus in VBA-M, Dolphin will freeze (don't panic, its OK!). Now load the GBA BIOS in VBA-M, after the splash screen Dolphin will recognize the joybus link and game will detect that a GBA was connected. Depending on the game, this can take upwards of five minutes. Enabling turbo mode in VBA-M and Dolphin (no frame limiter) can speed this up.
To connect other GBAs, just open another instance of VBA-M and repeat last instruction. Remember to unblock Dolphin and VBA-M in your firewall, some may block joybus link, leaving Dolphin stuck in connection screen. You can also refer to this video for more details.

What if you used the GC Controller Adapter by Mayflash with the GBA to GC adapter cord to connect the GBA to the PC? In the config for GC controller there is an option for GBA. Would dolphin check the other Mayflash port for the GBA? If not, could it be possible to add in that functionality?

I have made available a test build and am looking for test results. Please test this version out and post the results to the thread below. More information is available in the thread. This WIP build is a Windows build.
#9 Updated by Specs almost 5 years ago
I'm not sure whether this works with specific builds of both emulator but I can't get it to work in 4 player on 4swords with new or old builds. I can connect one virtual GBA with VBAM but after that it doesn't seem to detect the other VBAM windows and they all try to connect to controller port 1.

Four Swords Adventures+ - in Tetra's Trackers, after finishing a level, you're asked if you want to play another. The GBA reboots into the BIOS but then it seems to never re-establish the connection, so you must close and re-open Dolphin and the GBA emulator to play another level. Happens both with VBA-M and mGBA. [dolphin-master-5.0-13963-x64]

Hey reddit, so I recently thought I'd try out my first linux with an ubuntu dual boot on my windows 7 laptop.
I want to access my files (mainly my music) in ubuntu but I have run into some problems.
After googling it, I was lead to try to install Samba and smbfs, but for whatever reason it is not installing.
After aimlessly looking through forum posts and stuff I still havent been able to get samba or smbfs to install, and remain unable to find my windows 7 files.
Is there an easier way? If its not apparent, I have little to no idea what I am doing and could use some advice.
(I am in highschool and posting while in class (heh...) so I wont be able to respond immediately. Thanks for the help!)

Just right click the Cinnamon desktop, select "Open as root", then use
nemo with temporarily elevated privileges. Then close nemo, and I am

Have you tried nemo (cinnamon's file mgr) in KDE? It'll likely bring in
a bit of gtk stuff, but that shouldn't hurt anything.

How To Choose The Wave Grease
How do you choose the Wave Grease? You must consider many things, such as the brand name, price, and product quality. In addition, you should also consider whether it is suitable for your needs or not.
So how do you choose the right Wave Grease? Here are some tips that you can use to help you find a good product:
1. You first need to consider the product’s brand name. A good brand will always produce quality products, so a product with an established name should be good enough for your needs.
2. You need to consider the product’s price next. A high-quality product does not always mean that it will cost more, but if it costs too much, there must be something wrong, or nobody will buy it.
3. The final thing you need to look at is how well suited this item is for your needs and requirements and how well suited it is for others with similar requirements.
What you Should Keep in Mind When Buying Wave Grease
When shopping for Wave Grease, there are several things to consider. You need to think about the quality of the product, the price, and even how much it will benefit your life. However, you also need to keep these factors in mind:
Purchase from a reputable Brand
The finest product for you is that brand if you have your heart set on it. For instance, you should shop for a Samsung S9 phone online or at any other Samsung store if you wish to buy one.
Read reviews from others who have bought the product before. You must check what other customers have said about a product before buying it online, as this will help you determine whether it is worth buying or not. Suppose there are many positive reviews about an item and no negative ones. In that case, most people are happy with their purchase and would recommend it to others too.
Seal of approval
Look for the seal of approval. For example, look for the Energy Star seal if you’re shopping for a new printer. It indicates that the printer uses less energy than other models in its class.
It’s important to do your research before buying any new product. For example, check the minimum requirements listed on each model’s product page if you’re looking at laptops and want one with a larger hard drive. If they’re not listed, ask customer service or call the manufacturer directly before making your purchase.
Complete sure the website offers free shipping if you’re getting something online so that you don’t have to pay anything extra once you make your purchase. If the website doesn’t offer free shipping, think about making your purchase from a different site that does.
Many retailers offer extended warranties covering malfunctions, materials, or quality defects. If a product has this kind of coverage, it’s worth paying extra money upfront so that you don’t have to pay again later if something goes wrong with your purchase.
Ultimately, our Wave Grease reviews are designed to help you make a more informed purchasing decision. It’s much easier to decide when you know exactly what to look for and your options. We hope that this Keyword review article has helped. So if you’re looking for the best Wave Grease, we’re glad we could help. If you’re considering purchasing Wave Grease, we strongly recommend you look deeper at our top 10 Wave Grease reviews. Based on our research, we have found these excellent products to be well worth the money and should be able to meet your needs.

I am a user here and have no access to the grafana panel_s configuration, but I think this behaviour is strange so I want to report it here and if someone agrees, maybe make it a bug.
In one specific graph, I am presenting some number of records. it is an absolute number, no comma places. the lowest number is 9860, the highest number is 9872.
However, grafana displays this as “k”. And moreover, it adds more comma places than there are actual digits, and it invents a “,5” which in reality is not there. So the axis labellings read “9.86000 K” to “9.87250 K” which is questionable at least.

RadSpell uses a RadWindow for its dialog which, in turn, uses RadFormDecorator. Thus, RadSpell should expose its RenderMode property in order to allow the developer to make the popups consistent on the page (i.e. avoid mixing modes which is not supported) and to avoid styling issues with the dialog.
Currently the following web.config setting can be used to change the rendering mode of all RadWindows in the application, including the ones used by RadSpell:
<add key="Telerik.Web.UI.Window.RenderMode" value="Lightweight" />
and this one for the RadFormDecorators:
<add key="Telerik.Web.UI.FormDecorator.RenderMode" value="lightweight" />

The DVD-RW drive has been installed before. I formatted the HDDs & just didn't connect it up again as i have a blu-ray drive in there too which i was using.
Bought a PCIe card as i needed another SATA slot. This one to be exact: http://www.ebuyer.co...r-card-pexsat32
Anyway, i've connected everything up & the DVD-RW drive opens & closes but it's not recognized in My Computer at all.
In addition to this, the PCIe card installation manual says in Windows 7, it'll be listed under the "IDE ATA/ATAPI controller" category as "Standard AHCI device". As you can see, it doesn't mention Standard AHCI device.
How to get this working?
: I forgot to add - when i booted into Windows, it just said it needed to be restarted, but this didn't fix the problem.

Make your setting a character.
Writing is Rewriting
So how do you edit your book? Each author has their own method of madness, but many would agree that these steps are critical:
Beta readers are meant to edit your work. They can focus on different things, depending on their skill level and your needs/desires. But one thing's for sure: a good beta reader is worth their weight in gold.
Revision is re-envisioning
There's nothing akin to the agony of editing your book. This suffering goes beyond the whole "kill your darlings" because, at least for me, I'll gladly kill my darlings if it means saving my book.

UI for .NET MAUI
The Cartesian Series for .NET MAUI visualizes the ScatterArea Series as the area enclosed by the coordinate axes and straight line segments that connect the series data points. The ScatterArea Series inherits from the [ScatterPointSeries]() class and also requires both Chart axes to be Numerical Axes.
The Numerical axis chart type is an indispensable part of the Cartesian coordinate system. The chart type calculates the coordinate of each data point on its actual numerical value this point provides for the axis.
See the .NET MAUI Charts documentation: Numerical axis
The Telerik UI for .NET MAUI Charts Legend feature displays a set of items, which correspond to the chart content making it easy for you to provide descriptions for the series visualized within the control.
You can use annotations in your Telerik UI for .NET MAUI Charts whenever you need to highlight certain areas or points on the plot. You can easily define annotations on any point of the plot area and customize their appearance.

View Full Version : Extending Wireless Networks?
Jul 30, 2004, 05:13 PM
I don't understand the signal that a wireless base station sends, so I don't understand how the extending capabilities of an Airport Express function. When I sit at my desk upstairs, I get one to two bars from the Airport Extreme base station downstairs. It seems to me that if I plug my new Airport Express base station in up here, it'll only be picking up one or two bars and it is only extending a degraded network. I'm sure I'm not understanding this correctly, because that seems nearly useless. Can someone explain this too me in laymen terms what's going on?
Jul 30, 2004, 10:56 PM
FWIW, I just noticed that when enabling the wireless bridging function it warns that it may degrade the overall quality of the wireless network. I guess that limits how far you can bridge...
I still don't understand how the whole bridging thing can work though. A crappy signal is a crappy signal no matter what picks it up or how loud it repeats it.
Jul 30, 2004, 11:35 PM
I'm sure I'm not understanding this correctly, because that seems nearly useless. Can someone explain this too me in laymen terms what's going on?
The idea is that if your computer and your base station are too far apart, you would install the Express somewhere about half-way between the two. That way, it's in adequate proximity to talk to each, even if they're not close enough to talk to each other.
In light of this, installing the 'bridging' device right next to where you're going to use your computer would not be very helpful (they're both seeing the same signal anyway, as you point out).

Utah is an unbelievable state. Not only does Utah contain 5 wonderful national parks, enable fantastic skiing and mountain biking, host world-renowned movie festivals, and offer a world-leading standard of living and livability, it has a pretty interesting shape. Let's make a game out of the Utah-shaped pentomino.
The game board is a
n cube. Two players take turns filling in one
of each of the cells in this cube, like some 3D Tic-Tac-Toe. But instead of
n cells in row, each player is trying to be the first to make a
Utah-shaped pentomino out of their filled cells. Any orientation, rotation, or
reflection is allowed, with the exception of diagonal (slanted) moves. A
diagonal Utah-pentomino is not an allowed shape.
Here are some examples of layouts a player might try to play for.
X__ ___ ___ XX_ ___ ___ XX_ ___ ___
Above is a cube. The left 3x3 square is the bottom of the cube, the middle 3x3 square is the middle layer of the cube, and the right 3x3 square is the top layer of the cube. On the bottom layer, the Xs form a Utah-shaped pentomino.
Here is the cube in the sample image on this page:
___ _O_ ___ ___ OO_ ___ XX_ XXO X__
In this cube, the Utah-shaped pentomino is along the front side of the cube.
___ ___ ___ __X _XX _XX ___ ___ ___
This cube has an upside-down Utah-shaped pentomino down the center right of the cube.
An example of a diagonal shape that does not contribute to winning:
X__ _X_ __X X__ _X_ ___ ___ ___ ___
Clear as mud?
To try and help, we've constructed a visualization program. When you clone the
project repo, you'll find
visualizer.py in addition to the normal things.
(If for some reason this didn't work for you, you can
download it here.)
(http://vpython.org/) to be able to click around.
This visualizer is what generated the sample image on this page. Left-click
marks a box, right-click and drag rotates the view, and middle-click and drag
We'll be giving you game states over
stdin. Each game state will be exactly
one move away from either you or your opponent completing a Utah pentomino.
You will be next to play and need to make the optimum move. Your task is to
write a program that takes an arbitrary amount of these final-stage game
states and outputs the next game state after making your move. Your program
plays for the player placing
Xs (the other player is
Input game states will be
NxNxN cubes, newline separated, and
stdin will be
closed when no more game states need to be sent.

For output, just output the next game board state with your new move placed.

Recently I bought an HP Envy d001nl and I’m very happy with it, but yesterday I realized that the Realtek SD Reader was not working properly under Ubuntu 15.10 Wily. Not good, since I badly need the SD Card reader for copying photos from my Pentax K-30… Let’see what can be done.
First of all, it could be useful to exclude an hardware problem: I still have Windows 10 in my PC, barely used, but this time it proves to be useful, since it shows that the card reader is properly working. Using device manager I can find a few more details on this piece of hardware.
It is a Realtke PCIE CardReader with device ID 522A.
Back to Ubuntu, I verify this info with:
[email protected]:~$ lspci
02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 522a (rev 01)
A quick check on the Internet shows that the Realtek SD Reader is supported in the kernel since version 4.4, but unfortunately my Kubuntu version has kernel
[email protected]:~$ uname -r
The cleanest way to solve the problem is to build an updated kernel version, with the support for the card reader: there are a ton of pages that explain how to do that, so I won’t cover this kind of solution.
But suppose that you don’t want to change the kernel, there is still some chance to have the SD card reader properly working.
Disclaimer: I am not responsible of the damages you can do to your PC following this tutorial. Do it at your own risk.
That said, there should really be no problem if you take a bit of care.
The first step is downloading the kernel sources and the kernel headers:
[email protected]:~$ apt-get source linux
[email protected]:~$ sudo apt-get install linux-headers-generic
Four files are involved in the working of the Realtek SD reader:
include/linux/mfd/rtsx_pci.h drivers/mfd/rtsx_pcr.h drivers/mfd/rtsx_pcr.c drivers/mfd/rts5227.c
The right way to proceed would be to backport the changes related to the device identified by the id 522A (to avoid problems due to the different kernel versions), but luckily the driver seems not to be changed much between versions 4.2 and 4.4. This means that we can use the files of the 4.4 (or more recent) kernel version straight away.
For my PC I choose to use the driver source code files found in kernel 4.5; they can be downloaded from the github kernel repository:
Once downloaded, go to the root of the kernel sources
[email protected]:~$ cd linux-4.2.0
and copy respectively the above files in
rtsx_pci.h in include/linux/mfd/
rtsx_pcr.h in drivers/mfd/
rtsx_pcr.c in drivers/mfd/
rts5227.c in drivers/mfd/
Now it’s time to build the driver; copy your kernel configuration in the .config file to be used for kernel building
[email protected]:~/linux-4.2.0$ cp -vi /boot/config-`uname -r` .config
Copy the Module.symvers from the kernel headers package (more info related to the Module.symvers file here)
[email protected]:~/linux-4.2.0$ cp /lib/modules/$(uname -r)/build/Module.symvers ./
Build the modules:
[email protected]:~/linux-4.2.0$ make prepare [email protected]:~/linux-4.2.0$ make modules_prepare [email protected]:~/linux-4.2.0$ make SUBDIRS=drivers/mfd/
If all is fine, using the following command
[email protected]:~/linux-4.2.0$ ls drivers/mfd/*.ko | grep pci
you should see the line
Remove the old driver (if loaded)
[email protected]:~/linux-4.2.0$ sudo rmmod rtsx_pci
Make a backup copy of the old driver
[email protected]:~/linux-4.2.0$ sudo mv /lib/modules/$(uname -r)/kernel/drivers/mfd/rtsx_pci.ko /lib/modules/$(uname -r)/kernel/drivers/mfd/rtsx_pci.ko_ORIGINAL
Copy the new driver and regenerates the module dependencies
[email protected]:~/linux-4.2.0$ sudo cp drivers/mfd/rtsx_pci.ko /lib/modules/$(uname -r)/kernel/drivers/mfd/ [email protected]:~/linux-4.2.0$ sudo depmod -a
Finally, load the driver
[email protected]:~/linux-4.2.0$ sudo modprobe rtsx_pci
If the operations has been successful, once a SD card is inserted, you should see in the kernel log something like:
[ 4248.349559] rtsx_pci 0000:02:00.0: rtsx_pci_acquire_irq: pcr->msi_en = 1, pci->irq = 280 [ 4251.305275] mmc0: cannot verify signal voltage switch [ 4251.433049] mmc0: new ultra high speed SDR50 SDHC card at address aaaa [ 4251.447625] mmcblk0: mmc0:aaaa SU32G 29.7 GiB [ 4251.466839] mmcblk0: p1
and if you are using a desktop manager you should see the device:

- ItemLoad balancing location of emergency medical service stations(Technická Univerzita v Liberci, ) Jánošíková, Ľudmila; Gábrišová, Lýdia; Ježek, Bruno; Ekonomická fakultaWhen we want to design a successful and efficient emergency medical system, the crucial task is to determine the number of ambulances operating in a given region and the deployment of stations where the ambulances are kept. In the Slovak Republic, the number and locations of stations are specified by the Ministry of Health for the whole state territory. In the Czech Republic, the network of stations is established by the local authority for each administrative region. Due to geographical and population diversity, there are significant differences in population served by individual ambulances. Assuming that the number of ambulances is given, we want to investigate whether a different location of the ambulances might result in a more even distribution of their workload and, consequently, shorter response time. The problem is modelled as a capacitated p-median problem and solved using mathematical programming. The capacitated p-median problem is known to be NP-complete. As a consequence, it cannot be solved to optimality even for moderate-sized problem instances. However, we face a large-scale problem instance consisting of almost 3,000 demand nodes. Therefore heuristic approaches need to be used to get a sufficiently good solution in an acceptable time. Two decomposition mathematical heuristics are described in the paper and a new heuristic method based on previously developed approaches is presented. A redeployment of existing EMS stations in the Slovak Republic is calculated using these methods. The results are compared mutually and with the current deployment. The benefits and limitations of the presented methodology are discussed.

I am using sprintf in the following format : [sprintf %s%s:%s%s],
which lets me have a nice clock in a LCD (or message box probably) in
a format something like 12:45, or 01:56
now when i want to see negative values ( how long to wait until
something happens...) i can easily have -10:21 (still fine) but i
would like to have also -4:39...
meaning i would like the first %s (leftmost) to output nothing......
for the moment i just output a dot (.) so my format is .-4:54... but
is there a way to input something which will be output as nothing???

as well. Application servers, for example, typically specify a maximum permgen size of 128
MB, 192 MB, or more.
Contrary to its name, data stored in permgen is not permanent (metaspace, then, is a much
better name). In particular, classes can be eligible for GC just like anything else. This is a
very common occurrence in an application server, which creates new classloaders every time
an application is deployed (or redeployed). The old classloaders are then unreferenced and
eligible for GC, as are any classes that they defined. In a long development cycle in an ap-
plication server, it is not unusual to see full GCs triggered during deployment: permgen or
metaspace has filled up with the new class information, but the old class metadata can be
Heap dumps (see Chapter 7 ) can be used to diagnose what classloaders exist, which in turn
can help determine if a classloader leak is filling up permgen (or metaspace). Otherwise,
jmap can be used with the argument -permstat (in Java 7) or -clstats (in Java 8) to print
out information about the classloaders. That particular command isn't the most stable,
though, and it cannot be recommended.
1. The permanent generation or metaspace holds class metadata (not class data it-
self). It behaves like a separate heap.
2. For typical applications that do not load classes after startup, the initial size of this
region can be based on its usage after all classes have been loaded. That will
slightly speed up startup.
3. Application servers doing development (or any environment where classes are
frequently redefined) will see an occasional full GC caused when permgen/
metaspace fills up and old class metadata is discarded.
All GC algorithms except the serial collector use multiple threads. The number of these
threads is controlled by the -XX:ParallelGCThreads= N flag. The value of this flag affects
the number of threads used for the following operations:

Hi, I created a class that validate an user in NDS, but I need to get the value of one NDS parameter (called "Company") of the respective user. How can I do this? Please, I really need some help here. Thanks.
I hope this isn't for a homework assignment. Here's some code that might help you:
"myCtx" is an instance of "DirContext". "attrName" and "attrValue" are attribute name and value you want to search by. For example, it could be "cn" and "jbrown". The attribute value can contain wild cards, etc., just standard LDAP stuff. "searchScope" is one of teh valid "SearchControls.XXXX" values (ONELEVEL_SCOPE, OBJECT_SCOPE, SUBTREE_SCOPE, ...). Again pretty standard LDAP stuff. In the example here it will retrieve all of the attributes from the matching object and save the key/value pairs in a "TreeMap". It only handles String (text) attribute values nicely, and it doesn't have allowance for multi-value attributes. I'm sure you can add those if you need. It is fairly easy to modify this to handle multiple matches: this code only handles a single match, which is sufficient in many cases. Hope this helps ...

Most experienced change and configuration managers would gasp at the seeming low-tech inefficiency of index cards as means to track and report conformance and status. At the same time, it is hard to combat the efficacy of index cards to engage customers in a more participative and collaborative dialogue for eliciting requirements, and drawing simple diagrams - apparently, the physicality and tactile experience of the cards is simply more inviting and lets the customer do the writing instead of relying upon a single input-controlling scribe. (Some have suggested pair writing could be done between a developer and a customer in the same fashion that pair programming is done during implementation).
Even if index cards are used as the medium for initial capture of requests and requirements, many (if not most) change and configuration managers will want to subsequently transfer this information into a spreadsheet or a tracking system for fast and easy reporting, querying, searching, sorting, as well as for real-time dissemination across the project's organization and stakeholder-sites (not to mention affording more efficient and reliable storage, record retention, archival, and retrieval/recovery). Keeping stories in a tool also lets you apply a simple workflow see how the work is progressing.
Several agilists would argue that such a tool rails against the mandate of simplicity. To be certain, many have gone overboard with defining and enforcing process through a tool - we highly recommend against that since it often results in drastically increased administration overhead, drastically decreased face-to-face communication, and hence very low agility. On the other hand, many have had bad experiences with tools used to enforce too much process. We believe this, combined with bad experiences from misapplied CMM level climbing attempts, is responsible for much of the agile community's backlash against the use of more sophisticated but useful tools and processes.
The relentless focus on keeping things as simple as possible, and on face-to-face interaction over face-to-machine interaction still provides sound guidelines and important reminders when adopting processes and tools. With the right amount of process using a simple and smart tool, agile projects will find increased productivity and better coordination. The bottom line is really to do what you know works for you, and keep it as simple as possible, applying the principles of lean development every step of the way.
Change management is concerned with controlling and tracking changes to project and product scope and ensuring conformance to customer expectations. Agile change management is concerned with increasing the ability of the project to be responsive to requests for change and to quickly implement accepted change requests. This requires minimizing: the cost of effective knowledge transfer, the amount of knowledge captured in intermediate artifacts, and the time between making a decision and learning the effects of its result. The key success factors of agile change management are the use of iterative and incremental development with short feedback cycles, and close collaboration with frequent face-to-face interaction between developers and customers.
Sometimes the customer base is diverse and/or dispersed and a product manager role is needed to facilitate agreement from, and make decisions on behalf of the customer base. Participatory decision-making tends to produce the most collaborative results, and normative voting and effort allocation approaches have proved effective in reaching customer consensus to prioritize and plan the requests to implement at the beginning of an iteration. The product manager should be empowered to make decisions about issues that arise during an iteration, but either the product manager or a small sampling of customer reps can elaborate the details of a particular request to be implemented.
Index cards can be an effective means of engaging the customer during requirements capture, and simple tools (and processes) are an effective means of tracking, coordinating, and reporting visible progress of requests and changes against expected functionality and content. Don't be fooled by the allure of sophisticated processes and tools; and don't overcompensate by discarding simple but effective tools and techniques. Look for a balance of utility and simplicity that is both effective and efficient in meeting your change management needs. And keep an eye out for opportunities to eliminate redundant or unused elements of your processes, tools, and artifacts after each iteration.

This documentation is aimed at infrastructure developers, for Snabb infrastructure usage see the Snabblab section in Snabb manual.
Overview of Snabblab CI infrastructure
Source code for managing infrastructure for Snabb community providing tools to build, test and benchmark Snabb software to developers.
Under the hood, Nix language is used.
Source code serves two purposes:
Hydra is a [CI] (https://en.wikipedia.org/wiki/Continuous_integration) used by Snabb developers to test and benchmark different kinds of applications in Snabb. Relevant folders are
Server deployments using NixOps and Hydra. Relevant folders are
Motivations for Snabblab infrastructure
Following separate topics are all covered in this repository.
Snabblab is a group of servers with attached Networking cards on which Snabb can be developed and used. The cluster needs to be managed and deployed without too much hustle.
Snabb has unit and functional tests that require specific setup and environment to run successfully.
It's critical that Snabb doesn't regress in performance throughout development.
Different Snabb applications integrate into other software, requiring interesting set of software combinations to be benchmarked with.
- 10 different test cases.
- 5 versions of QEMU.
- 10 different guest VMs (Linux and DPDK).
- 16 combinations of Virtio-net options.
- 2 NUMA setups ("good" and "bad")
- 2 polling modes (engine "busy loop" and sleep/backoff)
- 2 error recovery modes (engine supervising apps vs process restart)
- 2 C libraries (glibc and musl)
- 3 CPUs (Sandy Bridge, Haswell, Skylake)
Be familiar with:
existence of basic Nix datatype manipulation functions
The very core of Hydra are jobsets. They define configuration how and when a specific Nix expression is executed.
Jobsets are grouped into projects for easier separation of concerns.
For example, snabb/master means master jobset for snabb project.
jobsets/snabb.nix expressions is evaluated using the highlighted function inputs that jobset configures.
The jobset configuration page defines:
jobsets/snabb.nixin input named
snabblab(which fetches https://github.com/snabblab/snabblab-nixos.git into Nix store).
snabbSrcfunction input as https://github.com/snabbco/snabb.git imported into Nix store
nixpkgsavailable in Nix search path to be imported anywhere in the expression
Once evaluation is triggered (every 300 seconds in this case), inputs are fetched and the whole Nix expression is evaluated. For each Nix derivation the hash is calculated and if it changes, the derivation is rebuilt.
An example evaluation shows that all jobs still succeed. Under the "Inputs" tab one can observe what inputs were used in this specific evaluation and due to Nix design and property of referential transparency, one should always get the same derivations for those inputs.
Each job can also provide "build products" which define what files are inside the resulting derivations and ready for download. Clicking on the manual job it lists different files representing manual formats contained inside the Nix store path.
- Snabb binary
- Snabb manual
- Snabb tests (make test)
- Snabb, not using Nix expression but rather packages on specific distribution (CentOS, OpenSUSE, Debian, Ubuntu, Fedora)
Note: clicking on specific jobset, on "Configuration" tab one can see what inputs are used for the Nix expression: here is an example.
The jobset will build all specified Snabb branches (
pairs). Additionally, you specify which
kernelVersions will be used. Using all these software versions, a big matrix
of combinations of inputs is computed and used to execute selected benchmarks.
benchmarkNames is a list of benchmark names
being executed on the matrix.
numTimesRunBenchmark input specifies how many times each benchmarks is
nixpkgs points to a specific commit, pinning all software used.
Once all benchmarks are executed, a big CSV file is generated based on results.
Last but not least,
reports is a list of reports names
that consumes the CSV and produces a nice report using R and markdown.
Under the hood of a specific benchmark (outputs)
Infrastructure behind a call to execute a benchmark consists of jobset function
outputs, spans over 700 lines in
jobsets/snabb-matrix.nix file and supporting
lib/ folder and begins at building all software used in the matrix.
Using sets of different (Snabb/Qemu/Dpdk/kernel) versions and names of benchmarks, a huge list of benchmark derivations is generated.
namejust being the identifier of the benchmark
checkPhasein bash executing the benchmark itself and writing output to stdout and a log file
toCSVtaking derivation result as input and extracting benchmarking value out of it
provides an environment in which all Snabb tests/benchmark are executed. All
software and environment settings are configured for
checkPhase to execute
correctly. For some benchmarks/tests
~/.test_env inside the chrooted
environment is populated using mkTestNixEnv
function that builds two qemu images (one plain NixOS and one with dpdk l2fwd
running) and corresponding
initrd kernel fixtures.
Using all executed benchmarks, [mkBenchmarkCSV] generates (https://github.com/snabblab/snabblab-nixos/blob/master/lib/benchmarks.nix#L200-217) one big CSV consisting of inputs specification and measures benchmarking values.
NixOps is used for provisioning the machines.
$ ssh firstname.lastname@example.org $ cd snabblab-nixos
It uses an sqlite database (
~/.nixops/deployments.nixops) to store state
about the provisioning. For example SSH keys, path to nix files, current

$ HETZNER_ROBOT_USER=<user> HETZNER_ROBOT_PASS=<pass> nixops deploy -d eiger -I nixpkgs=http://nixos.org/channels/nixos-16.09/nixexprs.tar.xz --include eiger
Copy generated Nix configuration into separate file:
$ nixops export -d lab-production | ./convert_export.py > ./machines/lab-export.nix
Note: this is very WIP and not all servers are deployed using this workflow yet.
A developer pushes a configuration change into Git, Hydra builds and tests it, servers are setup to automatically update themselves from Hydra. For each machine there is a separate channel that serves up that machine's software and configuration.

“Microsoft makes Notepad a separate Store app starting with new Windows 10 20H1 test build”. It allows customizing headers, footers, and margins before printing. The date, file name, and other information can be placed in the headers and footers with various codes consisting of an ampersand (‘&’) followed by a letter.
If Notepad is not up to date, it may not be compatible with Windows 11 and may cause errors. Notepad is a popular text-editing program that comes with Windows, but it can be prone to various errors. It is an invaluable tool for many users and can be incredibly frustrating when it stops working. Fortunately, there are a few things you can do to fix the issue.
Therefore, when making this update users will be able to access all the features available in the classic app as they are supported by RichEdit. That said, Show Unicode control characters will now work in this new version of the application which also includes emojis. Microsoft also announced new keyboard shortcut keys to help you manage tabs. Getting back the classic Notepad in Windows 11 can be useful if you don’t like the modern app that replaced it.

- This is located on the right-hand side of the main window.
Good luck and do not forget to check other techinal tips on mycodebit website. Notepad is the first built-in app to get a tabbed interface afterMicrosoft added tabs to File Explorerlast year. Microsoft first started testing tabs across all Windows 10 appsnearly five years ago in a featurenamed Sets. This would have added support for tabs inside Notepad, File Explorer, and many other apps, but Microsoft eventuallycanceled the projectand never shipped it to Windows 10 users. The obvious new feature in the redesigned Notepad is the dark mode. Learning how to do simple file management at the Command Prompt comes in handy when you’re learning to code.
2 How to Compare Two Files in Notepad++
The result is a list of the dictionary’s values. This ability to sort lists and other data containers by multiple positions is very helpful because you quite often need to sort data by multiple values. For example, if you have daily sale transactions data, you may need to sort the data first by day and then by transaction amount for each day. Or, if you have supplier data, you may need to sort the data first by supplier name and then by supply receipt dates for each supplier. The sorted and itemgetter functions provide this functionality. This example shows how to use the sorted function in combination with a key function to sort a collection of lists by the value in a specific index position in each list.
For JS/Angular/React I would suggest go with VSCode. I personally use it and prefer as its light weight and have good integration with chrome for frontend development. I couldn’t imagine using a development tool other than the IntelliJ IDEA Ultimate All Products Pack.

S0ix-states represent the residency in the Intel® SoC idle standby power states. The S0ix states shut off part of the SoC when they are not in use. The S0ix states are triggered when specific conditions within the SoC have been achieved, for example: certain components are in low power states. The SoC consumes the least amount of power in the deepest (for example, S0i3) state.
On Linux*, Android*, and Chrome* OS, ACPI-SState represent the system’s residency in the ACPI Suspend-To-RAM (S3). In the Suspend-To-RAM state, the Linux kernel powers down many of the systems’ components while maintaining the system’s state in its main memory. The system consumes the least amount of power possible while in the Suspend-To-RAM state. Note that any wakelock will prevent the system from entering the Suspend-To-RAM state.
This metric is collected as part of energy analysis. Collecting energy analysis data with Intel® SoC Watch is available for target Android*, Windows*, or Linux* devices. Import and viewing of the Intel SoC Watch results is supported with any version of the VTune Profiler.

With this function you can create a new sound index which can then be used in the regular audio functions to stream audio directly from an external OGG file source. The function requires the filename (which can be an included file, for example) and will return the new sound index for use. Note that after you no longer need the sound you should call the function audio_destroy_stream() with the sound index to remove it from memory otherwise you may get a memory leak which will slow down and eventually crash your game.NOTE: This functionality is not available for the HTML5 target platform.重要！该函数在试用版（Trial License）产品中不可用。
|filename||The file (OGG only) to stream the audio from.|
snd = audio_create_stream("Music/Track1.ogg");

The above code creates a new sound index in the variable "snd" from the given file, then plays this sound.

Functional programming (FP) has been around for the past six decades, and at the moment, attempts to overcome the ubiquitous dominance of object-oriented programming (OOP) continue. With the growth of popularity for machine learning (ML) and big data analysis, FP has gained demand due to the ease with which pure functions can be implemented. The functional paradigm also makes it easier to track, test, and maintain code for complicated assets, like data analysis, setting the stage for active use in the near future.
So, where does the interest in functional programming come from, and why is it worth learning FP languages? Let’s figure it out.
Crest of the wave of IT trends and the use of FP
In the IT world, nothing happens just like that. One thing clings to another, and now all the hottest trends are interconnected.
If we recall the most sensational trends of 2010th, these, of course, will be AI, IoT, Big Data, and Blockchain. They are on everyone’s lips, and everyone knows their potential and key features. And it is some of these trends that have catalyzed the rise in popularity of functional programming among developers.
Currently, the problem of parallel processing and work with large data streams is very acute, and one such example is the work with Big Data. And by parallelizing the processing of this data, you can get the desired result in a split second, which is critical in the real world. Plus, do not forget about decentralized (distributed) computing, blockchain, and others, which, in their essence, are a rather complex mechanism. And for such calculations, FP is most suitable due to the principles of functional programming (such as pure functions, for example). The use of FP techniques facilitates parallel code execution and maintenance. From which we can safely conclude: large IT companies tend to use functional programming more and more.
- Use JS with all its disadvantages.
- Find a solution to change the situation.
And it’s the time when TypeScript came to the stage.
What is TypeScript
The major advantage of introducing TypeScript is its strong typing. Typed variables help avoid bugs in code on the go, as the compiler monitors the correctness of all the implemented variable types, their consistency, and inheritance. Check this post if need more details about TS benefits.
Functional programming languages
Clojure, Elixir, Erlang, Elm, F #, Idris, Nix, Agda, and Haskell are the languages most often mentioned as the family of functional programming. And they will not lose their popularity for many years to come. Haskell is the most powerful language, my favourite one, but over time, later ones, such as Clojure, became intertwined with it, forming a general picture of the evolution of FP.
Let’s look at a few most popular and progressive functional programming languages.
Haskell is an unusual language from the point of view of those accustomed to Java, C ++, Python, or any other object-oriented language. The point is that Haskell is a functional language.
Haskell is too complicated for ordinary things, and you don’t need it for a simple website. It will be like reinventing the wheel. But great for making the server part, which will take over all the complex calculations, or decentralized layers for transactions, covering hundreds of thousands of operations. Haskell is best at accurate math and logic, so the better you know math, the easy will be for you to code in Haskell.
Almost everything in Haskell is done through functions. The task of the programmer is to find the mathematical function, which will be the solution for the task, and to describe the function to the compiler, mentioning:
- what parameters can come to the function,
- what to do with them,
- In what form the machine needs to give the result.
Haskell is a language that supports lazy evaluation. This means that he will calculate the required values in any function, not when the programmer runs it, but when this value is really needed in the calculation.
For example, we have a function that returns some value after being called. Haskell will not read if this value is not needed right now or is not used in a function call. It will wait until the function value is required, and only then will calculate it.
Lazy evaluation helps reduce the load on resources and makes programs faster and more efficient. If you write a calculator that does all the math but only uses addition, Haskell won’t even pay attention to the rest. He will know that you have a code that, if anything, can still multiply and divide, but he will not do anything with it yet.
What is Haskell good for?
- Text processing and parsing. In Haskell, it is easy to lay down the rules of any language, according to which language constructions are built, and to teach it to analyze this language. For example, he can divide sentences into words and prepositions, find connections between them, see if everything is written without errors, or find incorrect language constructions. This works both for common languages (English or German) and for programming languages, even for the design of new ones.
- Since Haskell does everything strictly according to the set of rules, it is an excellent tool for writing compilers. The task of any compiler is to convert the code, written in the high-level programming language, into the code understandable by the machine to execute it. So, Haskell is great at writing compilers. GHC (Glasgow Haskell Compiler, the main compiler for Haskell language) is also written in Haskell.
- Financial instruments. The main advantages of using Haskell for financial instruments are speed of operation, guaranteed accuracy, and the absence of bugs or discrepancies, which can lead to data leakage. Software written in Haskell can be systems for banking transactions, stock trading, risk analysis, or financial monitoring tools, etc.
- Industrial applications. Haskell is very flexible in defining the complex rules and process data according to these rules – this is exactly what enterprises need to build decision support or internal audit systems. This relieves the burden on people and allows algorithms to find points for industrial growth more efficiently.
It is a dynamic functional language designed for building scalable and maintainable applications. Elixir is powered by the Erlang VM ecosystem. It is used by Heroku, WhatsApp, Klarna, and other projects for distributed, fault-tolerant applications. Every element of applications is an expression, Erlang functions can be called without impacting runtime due to compilation of bytecode in Erlang and vice versa.
Elixir was released in 2012 by José Valim and was supported for several years only by its creator. At some point, its popularity grew so much that many companies began to use it in their projects seriously.
Elixir runs on top of the Erlang virtual machine. It is widely recognized for its unique capabilities for building fault-tolerant and distributed systems. Moreover, both in embedded devices, such as routers, when creating real-time applications (games, instant messengers).
Almost everything that is said about the Elixir is the merit of the Erlang virtual machine. Elixir was conceived as a language that brings something new to the world of Erlang, which Erlang itself lacked. First of all, these are tools that increase the level of abstraction (Struct, Protocol), allowing you to write more concise code (pipe operator, with construction), and it is convenient to manage the project and its dependencies (mix). It is also meta-programming, a powerful macro system that allows you to create DSL languages. A prominent example of such a DSL is the Ecto database library.
Elixir is a functional language. It is easy to learn and efficient to use. Based on it, the Phoenix web framework was created, which is very reminiscent of the simplified Ruby on Rails. It’s an open-source language and is available on GitHub.
As you probably already understood, you should not be afraid of functional programming. A little bit of diligence and curiosity, and now you have mastered FP. Given the prevalence of functional programming, you can be confident about your professional future (with due diligence), as you can surely be able to use your newly acquired skills.
In addition, I wish to say that learning FP languages changes your perception of programming in general, helps you look at problems from a new angle, forms abstract thinking, and lets you find non-standard and effective solutions to problems. If you are searching for the job of your life, functional programming can be such one.

[I am thinking of automating a supermarket queuing mechanism by implementing a Poisson queue distribution which will be in synchronised with other queues.
For instance 5-10 persons per queue on 1 counter. At each counter, an LCD will display the time taken per customer based on that corresponding queue.]
I am searching help for writing the code.
Problem: I have a supermarket whereby the clients need to search and then select the shortest queue. Suppose there are 4 queues such that each queue contains around 5-10 persons. I am thinking of automating this search by implementing a queuing mechanism (for e.g. Poisson Distribution). The queuing mechanism can be then synchronized with other queues at each counter. An LCD (as a display mean) can be used to inform the clients which queue they should take.
So, I want to know if this is possible.

|
code
|
I have a DEM in a Mosaic Dataset covering a large area (300 x 200 km). I want to create a classified slope raster showing slopes of say 0 - 10 degrees, 10 - 20 degrees, and then 20 - 90 degrees. Because the dataset is so large I want to avoid having to create a separate slope raster dataset, but instead use the Image Analysis so I can visually see where the slope classes are.
In the Image Analysis window I can create a Slope Function for my dem and display it using the Stretched color ramp in the Symbology tab of the Layer Properties. I want to use the Classified renderer, but Arc requires the data to have a histogram. When I say Yes, it chugs away computing the statistics and histogram. For really large datasets it can take a very long time. I'm wondering where the histogram and statistics are stored for a Image Analysis layer because it this Compute Histogram dialog keeps re-appearing.
I thought there could be a way to create this with a Function chain. There are functions called: Classify, Colormap, Remap that sound promising, but I haven't gotten any of them to work
The Classify function wants a .ECD or .ACT file as input. How do I create a ECD or ACT file or is there a better way to accomplish this?

There is some confusion around when to create a new app build version.
In App Store Connect, once an app build has been sent for review no changes can be made to that build number. A minor build
3.2.2 must be set for the next build created whether this is a TestFlight or release build. A way around this is to reject the current build, then it is possible to push another build to
This caused me some headache before I understood it.

Time Series Forecasting in Python: From Zero to Neural Networks in (Only) a Month
At the best of times, data science can be complicated, opaque, and dense with jargon, especially for those just starting to learn about it. This, at least, was my experience entering the field as a student intern for Wegaw with relatively limited prior knowledge in the details of how exactly you’re supposed to do something with a dataset.
However, with some research, the very helpful guidance of someone more experienced, some understanding of high-school statistics, and a few very useful Python libraries, I was ultimately able to make a couple of reasonably good predictions. Described below is the complete process I went through to get these predictions, in the hope that someone in the position I was in about a month ago will find it useful.
The data of interest in this case is the snow depth in certain measuring sites in British Columbia (BC). Predictions of future snow depth through methods like those described below can be a piece of a larger puzzle of tracking snowfall and snowmelt patterns in the region. That being said, a similar process can be used for almost any kind of data.
Finding the Data
Thankfully, this was the easy part. Like most developed countries with any amount of snowfall, Canada has a government agency that keeps reasonably good records of snowfall over time. In this case, the provincial government of BC has publicly available snow data that can be downloaded here.
This is the part of the article where I have to stress the principle of “Garbage In, Garbage Out”. It’s absolutely vital when doing this kind of work that relatively clean and reliable data be chosen so that results are accurate. It might therefore be worth going through a couple of different datasets to find ones without significant gaps: problems with the data can be fixed, but you can’t make data appear from thin air.
For this project, since I was intending to create a multivariate model, I picked three datasets measuring snow depth, temperature, and snow water content on an hourly basis from a single station near Aiken Lake, BC. The Aiken Lake data was in csv format, which I dealt with using the pandas library in Python.
Cleaning the Data
This was by far the most arduous process in the entire project, not necessarily because it was the most technical, but because it was the least interesting.
The first thing I did was get rid of all NaN values from the dataset; even the best datasets will have a couple, and getting rid of them meant working with only numerical data going forward.
To do this, two options presented themselves: I could either delete the rows containing NaN values, or just replace all NaN values with the mean of the previous two values. I chose the latter solution based on the assumption that the weather wasn’t likely to vary significantly from one hour to the next. Since there weren’t too many continuous NaN values, this wasn’t a problem.
Having done this, we can finally look at our data for the very first time:
Not very pretty.
The first thing that stands out is the extreme variation, in both the positive and negative directions. By scrolling through the raw data in Excel, it became obvious that this stemmed from an error with the order of magnitude of the data: instead of 8,000 cm of snow, there was really only 80.
The first step to fixing this was to take the absolute value of all the data; getting negative values for snow depth seemed unlikely. The next step was trying to find the right power of 10 to multiply/divide any outliers by so that they fell in line with the rest of the data.
Finding the outliers themselves wasn’t the main issue: because I was dealing with an order of magnitude problem, I assumed (probably correctly) that if the depth of the snow increases or decreases by a factor of 10 within an hour, something’s gone wrong.
The slightly harder part was figuring out what the order of magnitude is supposed to be. This is a relatively easy task for a person looking through the file in Excel, but a somewhat harder one to program efficiently. This is because the snow data I used is precise to the millimetre, which means that it ranges from 0.1 cm all the way up to about 120 cm: four orders of magnitude.
The solution I ended up implementing is as follows: if a correction is in order, Python checks if the previous value was corrected. If it was, it corrects the current value by the same amount as it corrected the previous one. Otherwise, it assumes that the order of magnitude of the previous value is the same as the true order of magnitude of the current value. This solution breaks if consecutive values are wrong by different orders of magnitude, but this approach was the simplest one I tested which still worked consistently.
The final correction I had to make was to remove any outliers (defined as values more than 3 standard deviations away from the mean) from the data that didn’t seem to be caused by any issues in the order of magnitude of the measurement; these were just random values that appeared in the data for no apparent reason. These were dealt with in the same way as NaN values: by replacing the outlier with the mean of the two previous values.
Having done all this to each of the three datasets, the cleaned data looks like this:
(Note: the temperature here is in Kelvin in order to keep the values from all the datasets positive. This made cleaning them easier.)
Using the handy
pandas.DataFrame.merge() function, I combined and downloaded these as one csv file.
Preparing the Data
Before running the models, however, there is one final matter I had to attend to. Almost all classical statistical models, including the ARMA and VAR models that I ended up using, require a stationary time series. Effectively, this means that the time series can’t have any time-dependant patterns or trends (a more detailed explanation of the concept of seasonality can be found here).
Looking at the data, it’s pretty obvious that a seasonal pattern is at play here; this is what we would expect from meteorological data like this. While it is possible to run seasonal ARMA models, they’re pretty power intensive, and the seasonality must be corrected for the VAR model to work properly anyway. This is most easily done by subtracting each value in the dataset from the value it had a year prior (eg. snow depth on the 1st of January 2021 at 00:00:00 is now equal to itself minus the snow depth on the 1st of January 2020 at 00:00:00). This is a process known as seasonal differencing.
Unfortunately, this means that the first year of our data is unusable, but there is still enough remaining for the models to train on.
The stationary data looks like this:
To make absolutely sure the data was stationary, I ran a unit root test on each dataset. I used the augmented Dickey-Fuller test provided by the statsmodels library (
statsmodels.tsa.stattools.adfuller()), although other options are available and equivalent.
For each of the datasets, the Dickey-Fuller test rejected the hypothesis that they have a unit root, implying that the data is stationary. More information on how unit root tests work and how they can be implemented can be found here.
I was now ready to run the models!
Modelling the Data
I used three approaches to try to forecast snow depth: a classical univariate, classical multivariate, and neural network approach. For each of these, different models was used.
Classical Univariate: ARMA
An ARMA (Autoregressive Moving Average) model uses past values of the dataset to forecast future values of the same dataset by combining different models into one. Consequently, I only used snow depth data for this model, since that’s what I wanted to predict.
Fully understanding what each component of the ARMA model does is essential in picking the right hyperparameters. Autoregressive (AR) models are models which use previous values to predict future values. For our purposes, the important thing we have to keep track of is how many previous values are used, also called the “order” of the model. As an example, an order 3 autoregressive model would use the three previous values of the dataset to predict the next one. (For more details, here’s a website I found useful.)
In a similar way, a moving average (MA) model uses past errors in the model to predict future values. Once again, the “order” of the model refers to how many steps you take back in time in order to predict the next value. (For more details, the same website as above has a pretty good explanation of MA models as well.)
An ARMA model is a combination of an AR and MA model, and requires two hyperparameters to work: the order of the AR model (p) and the order of the MA model (q), written as ARMA(p, q). Although there are more technical and systematic ways to pick these two hyperparameters, the easiest is to just try out a bunch of values and see which ones work best. For this, however, I had to start coding.
As with most statistical models, I was able to find a library that did most of the heavy lifting for me: the
statsmodels.tsa.arima.model.ARIMA() class, which takes as parameters a time series and an order in the form of a tuplet (p, d, q).
While this (an ARIMA model) is not the same as an ARMA model, we can set d equal to zero, and keep p and q as the orders of the AR and MA models respectively to create an ARMA model. If the data I used wasn’t stationary, I would have had to consider d more carefully, but the seasonal differencing was enough in this case to ensure stationarity.
I then split the dataset into train and test data, choosing the arbitrary cut-off point of January 1st, 2021, and applied the model to my train data. Testing a couple different values of p and q, and using RMSE to measure the quality of each resulting model, I arrived on an ARMA(1, 2) model as my solution.
Once the model was fitted, all I had to do was undo the seasonal differencing by adding the value of the previous year to each data point. This gives the following results:
Classical Multivariate: VAR
A vector autoregression model is like an autoregression model but using several time series to predict each other. In this case, I used past values of snow depth, temperature, and snow water content to make predictions about future values of snow depth. Like an AR model, it has an “order”, referring to how many previous values of each time series it will consider.
The actual programming is not too different from the ARMA: I once again divided the datasets into train and test, the only difference being all three time series were used instead of only snow depth. These help predict snow depth, assuming that they are all correlated with each other (which, looking at their plots above, they seem to be).
Like with the ARMA model, I used the
statsmodels.tsa.api.VAR() class to make predictions. Even more conveniently than the ARMA model, the statsmodels VAR class allows you to input a maximum order for the model, and simply checks every order for the model until that value, picking the right one using an information criterion that must be specified (I used the AIC, but others are available). These effectively judge the quality of the model by trying to balance the quality of the predictions and the quantity of parameters (to prevent overfitting).
The final step was to correct the seasonal differencing, and I got the following predictions:
(Note: since snow depth was what I was primarily interested it, that’s the only thing I plotted but the VAR model makes predictions for each one of the time series I inputted.)
The most striking thing about this model when compared to the ARMA model is its extreme degree of similarity. Because they have (slightly) different RMSEs, it’s clear that different models were run, but the extreme similarity does indicate that something may have gone wrong.
My guess is that the other time series added to the model (temperature, snow water content) were not sufficiently correlated with snow depth, so the model treated them as insignificant and basically just ran an autoregression model on the snow depth data.
In any case, however, a RMSE of about 13 cm is also pretty good in this case too.
An LSTM model is a neural network, and as such, was by far the most complicated model I tried to implement. In contrast with the other models, LSTM doesn’t actually require any differencing, since stationarity isn’t necessary.
I used a simple, “vanilla” LSTM; I was using a smaller amount of relatively uncomplicated data, so a more complicated model was unnecessary. In order to make it a multi-step model (with predictions more than one hour ahead), I used this vanilla LSTM as a vector output model: a kind of LSTM model that takes a vector as both an input and an output, with the output vector being the length of the prediction that we want (a length 30 vector corresponds to 30 hours ahead). For the model itself, I used the keras library for machine learning, and found an extremely helpful guide for how to write the code itself. Finally, I chose to make it a univariate model, and only used snow depth.
The main task when creating such a model was picking the right hyperparameters. There are three main ones: the number of epochs, the learning rate, and the number of units in the LSTM model. The only real way to pick any of these is to run a series of tests to find which one results in the lowest RMSE for the test data.
Once again, it is helpful to understand what each of these hyperparameters do so that they can be tuned correctly. The epochs is the number of times the model goes back over the parameters to correct them, which usually takes place in the order of 100–2,000. The units are the number of neurons in the LSTM, and usually number in the order of 10–200. The learning rate is a measure of how quickly the model changes to fit the problem, and has a value between 0 and 1.
As mentioned above, the only way to get specific values for hyperparameters is to test a bunch of them. LSTM models can take a while to work, especially with a large dataset, high number of epochs, or high number of units. Consequently, it is absolutely worth the time to automate the process: check each of the values for each of the hyperparameters automatically, and just get the value with the lowest RMSE for each one. As a final note, LSTM models contain a random element (the initial setting of all the parameters), so running it a couple of times and taking the average of the RMSE ensures that you’re not dismissing a perfectly good value for one of the hyperparameters by accident.
In my case, I had to turn my hourly data into daily data to get a prediction that goes any length into the future. Additionally, I could only try to predict a month in the future, since any more would take far too long to run. After testing in the way I described above, I came across values of 500 for the epochs, 75 for the number of units, and 0.01 for the learning rate. This gave me the following result, with an RMSE of 6.41(!):
By contrast, the ARMA model over the same period of time (using hourly data) looks like this and has an RMSE of 11.54:
It’s hard to know whether scaling up the problem for the LSTM (six or seven months, rather than just one) will result in the same quality of prediction, but doing so requires more time and computing power than I currently have on my hands. However, I think that, at least on this scale, this implementation of an LSTM can definitely be considered successful.
Before the end of the article, I just wanted to mention some generally useful tips for anyone who’s interested in starting.
- If you ever find yourself thinking “why hasn’t someone already written a method for this?” someone probably already has.
When I first started, I spent about three hours creating and testing a function that takes a string and turns into a
datetime.datetime() object, before discovering the pandas
to_datetime() method. Don’t make the same mistake I did.
- Understand the models you’re using
There are many, many websites and tutorials explaining the models described above with examples that you can very easily copy-paste into your IDE. This is fine, as long as you don’t then spend a few hours guessing different hyperparameters without even knowing what order of magnitude they’re supposed to be.
- Don’t be afraid to use other people’s work
This is probably the most important piece of advice I’d give to someone just starting: someone more experienced than you has already done a lot of the hard part for you. There are dozens of different libraries that do most of the technical computational part of the process behind the scenes. As long as you learn to use them properly, and have a vague understanding of what you need to do to make them work, you should implement them in whatever way you find useful.
The process of finding out more about data science and modelling through practical examples like these has been incredibly interesting and intellectually stimulating, and I would recommend to anyone interested in this field to start by getting some real data and working with it in a way similar to what I did.
Finally, I want to thank everyone at Wegaw for this opportunity, but especially Daria Ludtke for organising the internship, and Thomas James for his patience in taking me through some of the more complicated parts of the process.
