public interface ProcessingTarget
Rendering target to the Processing library.
Processing is using a Java2D mode so the underlying Processing object used is a PGraphicsJava2D object.
This render target supports two modes: applet or headless. The
applet mode is what is used in Gephi GUI and is backed by a PApplet
with zoom and pan control. The headless mode is tuned to work without GUI and
is typically used in exports. Either way users should use getGraphics()
method for drawing.
PreviewController.getRenderTarget(java.lang.String)
method users should define a width and height property in the
PreviewProperties
:
PreviewController previewController = Lookup.getDefault().lookup(PreviewController.class); PreviewModel model = previewController.getModel(); PreviewProperties props = model.getProperties(); props.putValue("width", 800); props.putValue("height", 600); ProcessingTarget target = (ProcessingTarget)previewController.getRenderTarget(RenderTarget.PROCESSING_TARGET);

Version control is something that's easy to take for granted when working by yourself on a project. You might accidentally delete something in your text file, but it's always just a press of the "undo" button away. Deleted an old folder, only to realize it had something you need in it? Don't worry, it's probably still in the computer's trash bin. Thanks to these types of features, we rarely screw up our work so badly that we can't get back to a functional version of it.
I learned about version control at this consulting firm where I used to work. We would receive heaps of operational data from clinics, mostly in the form of Excel spreadsheets. We got things like appointment times, durations, no-show status, doctor's name, etc. Our job was to comb through it and look for signs of inefficiency and ways to improve their productivity (riveting stuff!). In the beginning, it was just two of us and we could separate the work so as not to step on each other's toes.
Our team grew and in the end we had five people, all looking at the same dataset, all making different tables and charts. Like Gollum from The Lord of the Rings, our number one rule was this: protect the master! So, whenever we got a new dataset, the first thing we did was make our own personal copy before digging in. If anyone tampered with the master version, they were in for a good scolding.
Finally, we would write up a consultative report for the clinic managers, which meant we had to choose the most important findings each person had found and merge them back into one document. The bosses were kind of old-fashioned, so they usually wanted everything printed out. Because of this we had to make sure that not only file names, but also every page of every document had a version number and date on it. Sometimes one person's figures didn't match up with another person's figures, and we'd realize one of them was making calculation off the wrong version of the dataset!
Anyways, that model of version control wasn't quite the same as git, but it shared the same goals:
- Don't muck with the master version unless you're really, really sure.
- Allow lots of people to work on the same content at the same time.
- Be able to track changes incrementally, by date and author.
 You can make a copy of someone else's project by forking. Then you can branch from that copy to work on separate version or component without affecting the master's functionality. git also provides really thorough functionality for documenting and syncing changes.
GitHub is cool because it allows code to be accessed by anyone at any time. It also creates a social environment for open source development. You can even talk to it through git commands.
Who came up with that name, though?

This command will return to you the system timer value in milliseconds.
This is incredibly useful for precision timing of events. By reading this value into a variable, and checking it against the CURRENT time in milliseconds, you can perform 'waits' or check time lapses with a high degree of accuracy. A common use of this command is to seed the random number generator with the SeedRnd command. |

About Flat priors
I am a pharmacometrician and software engineer working in San Francisco (at UCSF and two startups). What you’ll find here are musings on pharmacometrics, applied statistics, software engineering, and other random geeky topics I find interesting. The title of this blog attempts to capture it’s unassuming nature and my attempt to keep an open mind to new science and technology.
So… why a blog, exactly?
- I like writing, and ‘practice makes perfect’, or in my case probably ‘slightly worse’ (but that doesn’t alliterate well)
- Writing a blog is much more fun that writing journal articles.
- I belief that many blogs (e.g. this one, and this one) have more direct and wide-spread impact on science than journal articles written by the same authors. Maybe not in a classical, high impact factor, peer-reviewed, gets-you-tenure kind of way, but more in an actual real-world sense. (Needless to say I wouldn’t dare compare this blog to those linked above).
- I can’t cram my thoughts in 140 characters, sorry.
Ron Keizer
PS. Many tools I talk about here are available at my Github repos, at Pirana Software, or at InsightRX.

atlassian
Businessmodel of Atlassian
Customer Segments
Atlassian has a mass market business model, with a multi-sided market; most of its consumer segments represent specific business functions and not industries – this means that its offerings can be used in different ways across different functions in the same organization. The company has taken advantage of this by building software ecosystems for various business segments, each representing a particular business function.
- Software (JIRA Software, BitBucket, Bamboo, Confluence, HipChat) – The company’s key offering, the JIRA Software, is aimed at streamlining software development. A number of the other offerings of the company, such as Bamboo and BitBucket, are targeted specifically at coders and software developers.
- IT (JIRA Software, IRA Service Desk, Confluence, HipChat) – The JIRA suite, including JIRA Service Desk and JIRA Software, allows IT teams to quickly respond to their organisation’s needs by maintaining effective feedback channels (through the Service Desk) and allowing for efficient and managed workflows (through the Software).
- Marketing (JIRA Core, Confluence, HipChat) – The company’s project management tools, including JIRA Core and Confluence, allow marketing teams to keep track of data and marketing material.
- Finance (JIRA Core, Confluence, HipChat) – JIRA Core is used by some of the largest financial institutions globally to manage financial processes such as procurement and financial reporting.
- Operations (JIRA Core, Confluence, HipChat) – JIRA Core allows operations managers to keep track of tasks, personnel, and deadlines. Confluence allows managers to set and communicate policies and operations documents.
- Human Resources (JIRA Core, Confluence, HipChat) – The Atlassian software suites, including JIRA Core and Confluence, can assist HR managers from recruitment and onboarding to personnel management.
- Legal (JIRA Core, Confluence, HipChat) – JIRA Core allows legal teams to create and manage legal materials including contracts and policies – these materials can be disseminated via Confluence. ### Value Proposition
Atlassian offers the following value propositions: Customisation, Price, Cost Reduction, Risk Reduction, and Convenience.
- Customisation – Atlassian recognizes that each business has different requirements and allows each business the freedom of choosing which of its products it wants in whichever combination it wants – the integrated nature of the products affords consumers this flexibility. This possibility of customization is furthered by the Atlassian Marketplace, where over 1,700 add-ons for the key products may be purchased to add additional features.
- Price – Atlassian works on a high-volume low-cost model. It spends far less than its competitors on sales and marketing, selling directly to consumers via its website. This allows it to charge far less for the same offering.
- Cost and Risk Reduction – By giving managers the ability to manage and further streamline their workflows, Atlassian provides a cost reduction to its clients by eliminating work-hours spend on unnecessary administrative tasks. In the same vein, the ability to manage workflows reduces the risk of mistakes or oversight in management.
- Convenience – By offering an integrated solution, Atlassian allows its clients to perform multiple functions on the same integrated platform. ### Channels
Atlassian’s only sales channel is direct online sales through its website. It does not have a sales team and spends only 15% to 20% of its revenue on sales and marketing. Compare this to a common figure of over 100% of revenue as marketing costs spent by tech companies within the first few years of an IPO.
Customer Relationships
Atlassian relies mainly on self-service – its website has a range of self-help material including product guides and live training. It also relies on community, through a community Q&A forum where clients can post questions which can be answered by other clients or by Atlassian staff, and through maintaining an experts program through which independent expert partners can sign up to assist Atlassian clients while showcasing their own products or services.
For personal assistance, Atlassian offers, at a fee, enterprise support services that provide technical account management through direct access to senior engineers in the company.
Key Activities
Atlassian’s key activity is the creation and maintenance of an integrated platform for customers to use for a variety of business functions.
Key Partners
Atlassian maintains an ecosystem of partners that create and sell add-ons for its services and that provide expert assistance to its clients. Some examples of partners include Adaptavist, Comalatech, and Zivra, all of which also serve Fortune 1000 companies.
Key Resources
Atlassian’s key resource is its people – it has over 1,400 employers in 6 offices in 5 different countries and spends over half of its expenses on R&D.
Cost Structure
Atlassian, unlike most other tech companies, spends only 15% to 20% of its revenue on sales and marketing. Its other key cost driver is research and development, at 40% to 45%. General and administrative expenses take up around 18% of total revenue.
Revenue Streams
Atlassian earns from subscription, maintenance, and perpetual license fees:
Revenue Stream Amount in FY 2015 ($’000) Proportion* Subscription 85,891 26.9% Maintenance 160,373 50.2% Perpetual License 57,373 17.5% Other 15,884 5.0% Total 319,521 100% *Figures are rounded and thus do not tally

March 18th, 2013
WHY are you playing video games? Dad came home. My living room was structured in such a way that everything was visible from the door. Turn that thing off.
Hmm… And after a pause, No. I was immersed in my game – my team needed me in the teamfight. I didn’t even look up at him.
Close that thing right now. Who told you you can play? Right, the first thing is to look for who to blame in this situation. Sigh, Asian parents when they’re angry.
Good question. Let me try and remember. I tried to picture his face as he stormed right up to me. In retrospect, a sarcastic comment while ignoring your dad was not the best idea here.
He came next to me and closed the lid of my laptop and looked at me. Didn’t I tell you to not play?
At the time all I could think of how my team could probably handle the rest of the game now. I mean we did just win a terribly one-sided teamfight. Really. It was totally in the bag. I let out a slight grin as I looked back up at dad. You know, I think you’re right. You did tell me not play.
Then don’t play.
Hmmm… I did my fake pondering act again. No. I proceeded to reach for the laptop. My dad’s forehead vein almost popped when he saw my hand move.
It’s always a mystery what a guy might do to another guy that’s making him furious. My tired dad from a long day of work probably thought about the various actions he could do. He came between the laptop and me, then kicked my chair. And I, still sitting in it, rolled back to the wall.
I acted as if I was stunned by that, and shook my head as if I was dizzy. I wasn’t actually, but I was enjoying the effect that it had. In typical disputes, the person who uses violence first has already lost the battle.
I stood up, and walked back to him, standing face to face. What do you want?
What do you think?
Perhaps there were better things to say; perhaps this whole engagement could have gone differently. For example, if he just told me to get the hell out the moment he had walked in, I might have submitted. He started with asking why, which I thought was weird and humorous. Perhaps it made me feel superior. At the end of the day, it is simply that I don’t respect my parents. What do I think? Don’t push me. I pushed him back.
…
I ended up spending the night at a conveniently-placed “Student Life Center” of a certain university next to my house. It was the second night that I was outside by myself. A good friend had convinced me that I should return home before tomorrow morning. When I came back late that night, I found the back door unlocked, and some food left on the kitchen table.
Eventually the grip my parents have over my behavior loosened, and they are starting to understand that I act based on my own interests and beliefs, but more importantly, that I can take care of my own affairs.
I can never say that I regretted how I acted that day. Something about me that just doesn’t regret things. I like to accept them, as a part of life. I did apologize to my dad the next morning, and he forgives me. Later I found out my parents had looked for me at the nearby McDonald’s, and all places that was open 24-hours. When they couldn’t find me, it was my dad that insisted on leaving the backdoor open. I am certain I do not appreciate my parents enough, and I may never do. Perhaps it is simply that they will always treat me like a child, overprotecting, and me always hating it.
— some eight months later —
Ahh, we forgot to order spring rolls! I said on our way out.
Hmm? My mom looks at me strangely. The sky was almost dark; we were in the restaurant for quite some time. I always liked the twilight.
Spring rolls! We forgot to order them! I repeated myself.
Why spring rolls? It’s not New Years or anything.
But we’ve just been to Spring Rolls dinner buffet, and we forgot to order spring rolls!
My dad started laughing. He was in a good mood that day. I just received an offer of admission from the university. A stone landed safely on the bottom of my parent’s hearts.
Can we walk home?
What about the car?
Get it tomorrow?
From what, the police station?
Do you think they would pity us if we said we forgot to order spring rolls from Spring Rolls?
Get in the car.

UseOpsworksSecurityGroups
-
Whether to associate the AWS OpsWorks Stacks built-in security groups with the stack's layers.
AWS OpsWorks Stacks provides a standard set of built-in security groups, one for each layer, which are associated with layers by default. With
UseOpsworksSecurityGroups
you can instead provide your own custom security groups.UseOpsworksSecurityGroups
has the following settings:-
True - AWS OpsWorks Stacks automatically associates the appropriate built-in security group with each layer (default setting). You can associate additional security groups with a layer after you create it, but you cannot delete the built-in security group.
-
False - AWS OpsWorks Stacks does not associate built-in security groups with layers. You must create appropriate EC2 security groups and associate a security group with each layer that you create. However, you can still manually associate a built-in security group with a layer on creation; custom security groups are required only for those layers that need custom settings.
For more information, see Create a New Stack.
Required: No
Type: Boolean
Update requires: No interruption
-
VpcId
-
The ID of the VPC that the stack is to be launched into. The VPC must be in the stack's region. All instances are launched into this VPC. You cannot change the ID later.
-
If your account supports EC2-Classic, the default value is
no VPC
. -
If your account does not support EC2-Classic, the default value is the default VPC for the specified region.
If the VPC ID corresponds to a default VPC and you have specified either the
DefaultAvailabilityZone
or theDefaultSubnetId
parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks sets these parameters to the first valid Availability Zone for the specified region and the corresponding default VPC subnet ID, respectively.If you specify a nondefault VPC ID, note the following:
-
It must belong to a VPC in your account that is in the specified region.
-
You must specify a value for
DefaultSubnetId
.
For more information about how to use AWS OpsWorks Stacks with a VPC, see Running a Stack in a VPC. For more information about default VPC and EC2-Classic, see Supported Platforms.
Required: No
Type: String
Update requires: Replacement

Return values
Ref
When you pass the logical ID of this resource to the intrinsic Ref
function, Ref
returns the resource name. For example:
{ "Ref": "myStack" }
For the AWS OpsWorks stack myStack, Ref
returns the AWS OpsWorks stack ID.
For more information about using the Ref

Colleagues,
I wanted to share the below digital resources that are available to you and your students. Information about free broadband is especially important for distance learning.
Patty
With an unprecedented number of schools closing and students across the country shifting to digital learning because of COVID-19, Verizon has made digital resources available to schools and teachers across the country.
The Verizon Innovative Learning Schools Connection website has a number of resources including tips to prepare for and implement robust digital learning plans and Verizon’s partner Digital Promise has helpful COVID-19 online learning resources and FAQs.
Knowing many students also rely on schools for more than learning, Verizon is working with nonprofit partners to ensure children from low-income families still have access to healthy meals while their schools are closed.
Altice USA and Charter Communications both announced on March 13, 2020 that they would offer free broadband services to students taking online classes. Both providers cover different parts of New York City.
Charter announced that it would offer free high-speed Spectrum Internet service and Wi-Fi for 60 days to households with students taking online classes because of the coronavirus outbreak. Students can call<PHONE_NUMBER> to enroll. Installation fees will be waived for new student households, the company said. Spectrum said regular pricing will take effect at the end of the 60-day period if a customer doesn’t cancel or change the service. For more information, see https://corporate.charter.com/newsroom/charter-to-offer-free-access-to-spectrum-broadband-and-wifi-for-60-days-for-new-K12-and-college-student-households-and-more
Altice USA said that it would offer Altice Advantage 30 mgbs broadband service for free to college students without Internet service for 60 days. Eligible students can call<PHONE_NUMBER> to enroll. For more information see https://www.alticeusa.com/news/articles/feature/corporate/altice-usa-brings-free-broadband-k-12-and-college-students-during-coronavirus-pandemic
In addition, AT&T, Verizon, T-Mobile, Sprint and Comcast have announced additional services during the coronavirus outbreak, such as the removal of data caps and waiver of late fees. Students should check with their individual carriers for these arrangements. https://www.cnet.com/news/carriers-are-suspending-internet-data-caps-during-coronavirus/

Check if a process is registered to run under DynamoRIO. To obtain client information, use dr_get_client_info().
| [in] | process_name | A NULL-terminated string specifying the name of the target process. The string should identify the base name of the process, not the full path of the executable (e.g., calc.exe). |
| [in] | pid | A process id of a target process, typically just created and suspended via dr_inject_process_exit(). If pid != 0, the one-time configuration for that pid will be queried. If pid == 0, the general configuration for process_name will be queried. |
| [in] | global | Whether global config files, stored in a dir pointed at by the DYNAMORIO_HOME registry key, should be used, or local config files private to the current user. Administrative privileges may be needed if global is true. Note that DynamoRIO gives local config files precedence when both exist. The caller must separately create the global directory. |
| [in] | dr_platform | Configurations are kept separate on 64-bit Windows for 32-bit (WOW64) processes and 64-bit processes. This parameter allows selecting which of those configurations to check. |
| [out] | dr_root_dir | If the process is registered, the root DynamoRIO directory provided at registration. Callers can pass NULL if this value is not needed. Otherwise, the parameter must be a caller-allocated array of length MAX_PATH. |
| [out] | dr_mode | If the process is registered, the mode provided at registration. Callers can pass NULL if this value is not needed. |
| [out] | debug | If the process is registered, the debug flag provided at registration. Callers can pass NULL if this value is not needed. |
| [out] | dr_options | If the process is registered, the extra DynamoRIO parameters provided at registration. Callers can pass NULL if this value is not needed. Otherwise, the parameter must be a caller-allocated array of length DR_MAX_OPTIONS_LENGTH. |

| ) |
Register a client for a particular process. Note that the process must first be registered via dr_register_process() before calling this routine.
| [in] | process_name | A NULL-terminated string specifying the name of the target process. The string should identify the base name of the process, not the full path of the executable (e.g., calc.exe). |
| [in] | pid | A process id of a target process, typically just created and suspended via dr_inject_process_exit(). If pid != 0, the one-time configuration for that pid will be modified. If pid == 0, the general configuration for process_name will be modified. |
| [in] | global | Whether global config files, stored in a dir pointed at by the DYNAMORIO_HOME registry key, should be used, or local config files private to the current user. Administrative privileges may be needed if global is true. Note that DynamoRIO gives local config files precedence when both exist. The caller must separately create the global directory. |
| [in] | dr_platform | Configurations are kept separate on 64-bit Windows for 32-bit (WOW64) processes and 64-bit processes. This parameter allows selecting which of those configurations to unset. |
| [in] | client_id | A client_id_t uniquely identifying the client. DynamoRIO provides the client ID as a parameter to dr_init(). Clients use this ID to retrieve client-specific path and option information. Outside entities also identify the target of a nudge via this ID. |
| [in] | client_pri | The client number, or priority. Client registration includes a value indicating the priority of a client relative to other clients. In multi-client settings, a client's priority influences event callback ordering. That is, higher priority clients can register their callbacks first; DynamoRIO then calls these routines last. Client priorities range consecutively from 0 to N-1, where N is the number of registered clients. Specify priority 0 to register a client with highest priority. |
| [in] | client_path | A NULL-terminated string specifying the full path to a valid client library. The string length cannot exceed MAX_PATH. The client path may not include any semicolons. |
| [in] | client_options | A NULL-terminated string specifying options that are available to the client via dr_get_options(). The string length cannot exceed DR_MAX_OPTIONS_LENGTH. The client options may not include any semicolons. |

| const char * | dr_options | |||
| ) |
Register a process to run under DynamoRIO. Note that this routine only sets the base options to run a process under DynamoRIO. To register one or more clients, call dr_register_client() subsequently.
| [in] | process_name | A NULL-terminated string specifying the name of the target process. The string should identify the base name of the process, not the full path of the executable (e.g., calc.exe). |
| [in] | pid | A process id of a target process, typically just created and suspended via dr_inject_process_exit(). If pid != 0, a one-time configuration is created just for it. If pid == 0, a general configuration is created for all future instances of process_name. |
| [in] | global | Whether global config files, stored in a dir pointed at by the DYNAMORIO_HOME registry key, should be used, or local config files private to the current user. Administrative privileges may be needed if global is true. Note that DynamoRIO gives local config files precedence when both exist. The caller must separately create the global directory. |
| [in] | dr_root_dir | A NULL-terminated string specifying the full path to a valid DynamoRIO root directory. The string length cannot exceed MAX_PATH. |
| [in] | dr_mode | Specifies the mode under which DynamoRIO should operate. See dr_operation_mode_t. |
| [in] | debug | If true, a DynamoRIO debug build will be used; otherwise, a release build will be used. |
| [in] | dr_platform | Configurations are kept separate on 64-bit Windows for 32-bit (WOW64) processes and 64-bit processes. This parameter allows selecting which of those configurations to set. |
| [in] | dr_options | A NULL-terminated string controlling DynamoRIO's behavior. Most users should not need to specify options. The total string length cannot exceed DR_MAX_OPTIONS_LENGTH. |
| dr_config_status_t dr_register_syswide | ( | dr_platform_t | dr_platform, | |
| const char * | dr_root_dir | |||
| ) |
Sets up systemwide injection so that registered applications will run under DynamoRIO however they are launched (i.e., they do not need to be explicitly invoked with the drrun or drinject tools). This requires administrative privileges and affects all users (though configurations remain private to each user). On Windows NT, a reboot is required for this to take effect.
| [in] | dr_platform | Configurations are kept separate on 64-bit Windows for 32-bit (WOW64) processes and 64-bit processes. This parameter allows selecting which of those to use. |
| [in] | dr_root_dir | The root DynamoRIO directory (used to locate drpreinject.dll). |
| bool dr_registered_process_iterator_hasnext | ( | dr_registered_process_iterator_t * | iter | ) |

| [out] | debug | If the process is registered, the debug flag provided at registration. Callers can pass NULL if this value is not needed. |
| [out] | dr_options | If the process is registered, the extra DynamoRIO parameters provided at registration. Callers can pass NULL if this value is not needed. Otherwise, the parameter must be a caller-allocated array of length DR_MAX_OPTIONS_LENGTH. |

| bool | global | |||
| ) |
Creates and starts an iterator for iterating over all processes registered for the given platform and given global or local parameter.

With .NET Core, we get a lot of stuff for free. If you so choose, wiring up your applications (ASP.NET or Console) with things like Dependency Injection, Configuration and Logging is as simple as can be. .NET Core bakes these features into the framework and usage of does not require a trade-off of power or flexibility.
Following, I will walk you through getting up and running with all three of these items in a .NET Core console application.
Be sure to head over to the git repository that supports this post at - Pioneer Console Boilerplate
First thing first, let's create a new project. Open up Visual Studio, hit Ctrl+Shift+N and select the Console Application ( .NET Core) project type from the templates.
Visual studio will scaffold a project for you which will end up looking like this.
.NET Core is all about opting into dependencies as opposed to opting out. That being said we will need to pull in a few NuGet packages to facilitate our needs. Open up your project.json file and add the following packages to your dependencies node. Versions might differ depending on what version of .NET Core you are using.
"dependencies": { "Microsoft.NETCore.App": "1.1.0", "Microsoft.Extensions.DependencyInjection": "1.1.0", "Microsoft.Extensions.Configuration.Json": "1.1.0", "Microsoft.Extensions.Configuration.FileExtensions": "1.1.0", "Microsoft.Extensions.Configuration": "1.1.0", "Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0", "Microsoft.Extensions.Logging": "1.1.0", "Microsoft.Extensions.Logging.Console": "1.1.0", "Microsoft.Extensions.Logging.Debug": "1.1.0" }
Fair warning, project.json is on its way out in favor of .csproj. As of the date this was published, this transition is already available in the Visual Studio 2017 release candidate.
Now that our project is ready, we need to wire up our dependency injection container so we have a means to register the individual components we will be using in our program. For this demonstration, we will be registering a new service called TestService. Go ahead and create a new file called TestService.cs and add the following.
public interface ITestService { } class TestService : ITestService { }
To maintain a separation of concern between our business based logic and the logic we use to configure and run the actual console application, let's create a new class called App.cs. The goal being that we will use Program.cs to bootstrap everything need to support our application and then fire off all the logic that is needed to support out "business" needs by way of executing the Run() method in App.cs.
public class App { private readonly ITestService _testService; public App(ITestService testService) { _testService = testService; } public void Run() { _testService.Run(); System.Console.ReadKey(); } }
App.cs needs an object that meets the ITestService interface contract. This object will be passed in through our dependency manager.
Open up your Program.cs file and add the following.
public class Program { public static void Main(string[] args) { // create service collection var serviceCollection = new ServiceCollection(); ConfigureServices(serviceCollection); // create service provider var serviceProvider = serviceCollection.BuildServiceProvider(); // entry to run app serviceProvider.GetService<App>().Run(); } private static void ConfigureServices(IServiceCollection serviceCollection) { // add services serviceCollection.AddTransient<ITestService, TestService>(); // add app serviceCollection.AddTransient<App>(); } }
Our console app starts out in Main. Here we create a new ServiceCollection object and configure it inside of ConfigureServices. In ConfigureServices we add our dependencies to the container collection, of which can have a lifetime of Scoped, Transient or Singleton. Once the ServiceCollection object is configured, we then need to request an IServiceProvider (Dependency Management Container) from our ServiceCollection object in order to manually resolve our App class and kick our logical loop off by calling its Run() method.
For more information on service lifetime and registration options, visit .NET Dependency Injection.
Now that we have our Dependency Injection wired up, we need to setup logging. More specifically, we need to log to the console so that we can visually verify that not only our App.Run() method is being called but also that our ITestService is being injected and ran from the App class.
Open of Program.cs again and update the ConfigureServices method with the following.
private static void ConfigureServices(IServiceCollection serviceCollection) { // add logging serviceCollection.AddSingleton(new LoggerFactory() .AddConsole() .AddDebug()); serviceCollection.AddLogging(); // add services serviceCollection.AddTransient<ITestService, TestService>(); // add app serviceCollection.AddTransient<App>(); }
We first add new instances of ILoggerFactory for the Console (outputs to the console) and Debug (writes log output by way of System.Diagnostics.Debug) providers. Both providers will have a Singleton lifetime. Finally, we add our logging services to your service collection.
Update the App class with the following.
public class App { private readonly ITestService _testService; private readonly ILogger<App> _logger; public App(ITestService testService, ILogger<App> logger) { _testService = testService; _logger = logger; } public void Run() { _logger.LogInformation($"This is a console application for {_config.Title}"); _testService.Run(); System.Console.ReadKey(); } }
We now are injecting an instance of ILogger<App>. Of which we are using to LogInfromation inside our Run() method. Additionally, we are calling the ITestService.Run() of our injected service to further illustrate that our dependency injection is actually managing dependencies correctly.
Update the TestService class and interface with the following.
public interface ITestService { void Run(); } class TestService : ITestService { private readonly ILogger<TestService> _logger; public TestService(ILogger<TestService> logger) { _logger = logger; } public void Run() { _logger.LogWarning("Wow! We are now in the test service."); } }
Much like App.cs we inject an instance of ILogger<TestService> and perform a LogWarning inside of ITestService.Run().
If we run our console app now, we should end up with something like the following. Of which shows our path down to the ITestService instance through our logging.
Typically you will need some kind of configuration to manage your app's deployment. Luckily, .NET Core offers up a clean and lightweight method of pulling in configuration through a JSON file.
Create a file called app-settings.json and add the following.
{ "Configuration": { "Title": "Pioneer Console Boilerplate" } }
Create a file called AppSettings.cs and add the following. We will use this model to deserialize our app-settings.json file into.
public class AppSettings { public string Title { get; set; } }
Update Program.ConfigureServices with the following.
private static void ConfigureServices(IServiceCollection serviceCollection) { // add configured instance of logging serviceCollection.AddSingleton(new LoggerFactory() .AddConsole() .AddDebug()); // add logging serviceCollection.AddLogging(); // build configuration var configuration = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile("app-settings.json", false) .Build(); serviceCollection.AddOptions(); serviceCollection.Configure<AppSettings>(configuration.GetSection("Configuration")); // add services serviceCollection.AddTransient<ITestService, TestService>(); // add app serviceCollection.AddTransient<App>(); }
We use a ConfigurationBuilder object to...
We then call AddOptions() on our IServiceCollection object to add services needed to use the Options pattern inside of our app. In short, the Options Pattern allows us to decouple feature configuration in our application and bind said feature configuration to independent models.
Finally, we register the IConfigurationRoot instance, which our Options will bind against.
Open up your App class and update it with the following.
public class App { private readonly ITestService _testService; private readonly ILogger<App> _logger; private readonly AppSettings _config; public App(ITestService testService, IOptions<AppSettings> config, ILogger<App> logger) { _testService = testService; _logger = logger; _config = config.Value; } public void Run() { _logger.LogInformation($"This is a console application for {_config.Title}"); _testService.Run(); System.Console.ReadKey(); } }
Open up your TestService class and update it with the following.
class TestService : ITestService { private readonly ILogger<TestService> _logger; private readonly AppSettings _config; public TestService(ILogger<TestService> logger, IOptions<AppSettings> config) { _logger = logger; _config = config.Value; } public void Run() { _logger.LogWarning($"Wow! We are now in the test service of: {_config.Title}"); } }
In both updates, we inject an IOptions<t> with a type of AppSettings. This means we will get an object that has our app-settings.json config file deserialized into that object. Of which, we use to print our Title variable out with our logging message.
Run the application and you should now get something that looks like this.
And that is that. .NET Core makes adding configuration, logging and dependency injection simple to add into your app no matter the type. As always, if you have any comments be sure to let me know below.

@InProceedings{ mckinney-proc-scipy-2010, author = { {W}es {M}c{K}inney }, title = { {D}ata {S}tructures for {S}tatistical {C}omputing in {P}ython }, booktitle = { {P}roceedings of the 9th {P}ython in {S}cience {C}onference }, pages = { 56 - 61 }, year = { 2010 }, editor = { {S}t\'efan van der {W}alt and {J}arrod {M}illman }, doi = { 10.25080/Majora-92bf1922-00a } }
Brand and logo
When using the project name pandas, please use it in lower case, even at the beginning of a sentence.
The official logos of pandas are:
Primary logo
Secondary logo
Logo mark
Logo usage
The pandas logo is available in full color and white accent. The full color logo should only appear against white backgrounds. The white accent logo should go against contrasting color background.
When using the logo, please follow the next directives:
- Primary logo should never be seen under 1 inch in size for printing and 72px for web
- The secondary logo should never be seen under 0.75 inch in size for printing and 55px for web
- Leave enough margin around the logo (leave the height of the logo in the top, bottom and both sides)
- Do not distort the logo by changing its proportions
- Do not place text or other elements on top of the logo

Code completion result for source line: ba.r|esolve(); (QueryType=COMPLETION, prefixSearch=false, caseSensitive=true) ------------------------------------ METHOD resolve(): String [PUBLIC] path.js
Resolves to
to an absolute path.
If to
isn't already absolute from
arguments are prepended in right to left
order, until an absolute path is found. If after using all from
paths still
no absolute path is found, the current working directory is used as well. The
resulting path is normalized, and trailing slashes are removed unless the path
gets resolved to the root directory. Non-string from
arguments are ignored.
Another way to think of it is as a sequence of cd
commands in a shell.
path.resolve('foo/bar', '/tmp/file/', '..', 'a/../subfile')
Is similar to:
cd foo/bar
cd /tmp/file/
cd ..
cd a/../subfile
pwd
The difference is that the different paths don't need to exist and may also be files.
Examples:
path.resolve('/foo/bar', './baz')
// returns
'/foo/bar/baz'
path.resolve('/foo/bar', '/tmp/file/')
// returns
'/tmp/file'
path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif')
// if currently in /home/myself/node, it returns
'/home/myself/node/wwwroot/static_files/gif/image.gif'


According to the computations by Nakamura, Johnson, and Mason1 this will result in the complete annihilation of both particles.


Mission
The Attackerspace will be an open meeting place for collaboration, outreach, training, hackathons, movies nights, and generally accessing hardware, software, and tools not easily accessed by individuals. Unlike other hackerspaces and makerspaces, the Attackerspace specifically emphasizes information security and related topics.
The Lab
The lab is actively building out the the physical architecture. When finished, the lab will contain the following core elements:
- WaspNest CTF: Stop by to live, or contact us to host WaspNest at your next event
- Wireless lab: Commercial and enterprise WAPs for securing and attacking
- Mobile lab: A variety of rooted and unrooted Android and iOS targets
- Training lab: Endpoints and a PXE server for training use
- Cisco stack: One of the biggest obstacles in CCNA training is acquiring practice gear; come use ours
- Lock picks: And practice locks
- Community library: Books, movies, and games
- Infosec archives: Video training, slides, password lists, POC code, VMs, and more
