Your vi clone of choice can be configured in several ways.
A variety of commands can be entered while in command mode to set up vi just how you like it. Depending on your editor, you can enable features to make programming easier (like syntax hilighting, auto-indenting, and more), set up macros to automake tasks, enable textual substitutions, and more.
Almost all of these commands can be put into a configuration file in your home directory. elvis expects a .exrc file, while vim expects a .vimrc file. Most of the setup commands that can be entered in command mode can be placed in the configuration file. This includes setup information, textual substitutions, macros, and more.
Discussing all these options and the differences between the editors is quite an involved subject. For more information, check out the man page or web site for your preferred vi editor. Some editors (like vim) have extensive help within the editor that can be accessed with the :help command, or something similar. You can also check out the O'Reilly book Learning the vi Editor by Lamb and Robbins.
Many common programs in Linux will load up a text file in vi by default. For example, editing your crontabs will start up vi by default. If you do not like vi and would like another editor to be started instead, all you need to do is set the VISUAL environment variable to the editor you prefer. For information on setting environment variables, see the section called Environment Variables in Chapter 8. If you want to make sure that your editor will be the default every time you login, add the VISUAL setting to your .bash_profile or .bashrc files.


The Shotover U1 cinema drone is the most sophisticated, capable and safe remote aerial filming platform in the world and Flying Glass is proud to be one of the first companies to bring this to the UK and Europe.
The Shotover U1 sets a new standard for drone cinematography and imaging as the first solution to accommodate cinema quality cameras and lenses. We can fly amazing combinations including the 6K RED Weapon Dragon, Arri Alexa Mini, Phantom Flex 4K, Panasonic Varicam LT and Sony F55 cameras with Arri, Canon, Fujinon and Angenieux zoom lenses. This flexibility allows us to carry the right payload for whatever the mission requires.
Further increasing functionality, the Shotover U1 gimbal (G1) can be detached from the multirotor and used as a standalone gyro-stabilized platform for mounting on motorcycles, cars, boats, cables and almost anything that moves. Other U1 features include redundant flight control and battery systems, customized downlink with two HD video feeds and unparalleled stability even at full zoom.
The Shotover U1 builds upon Shotover’s expertise in the aerial cinematography industry with its class leading Shotover F1 and Shotover K1 gyro-stabilized camera systems. Recent credits include Hollywood blockbusters Jurassic World, Furious 7 and Spectre; Shotover has also been tapped by the BBC for filming telephoto 4K footage of wolves, bears and caribou in Canada’s remote Northwest Territories for a six-part wildlife documentary series scheduled to air in 2016.
The Shotover U1 is the first drone specifically designed for broadcasters and big budget filmmakers, allowing productions to employ the same professional grade cameras and lenses they choose for their principal photography. Coupled with unsurpassed reliability and support, the Shotover U1 will enable cinematographers to capture breathtaking shots, including those that wouldn’t be possible with a helicopter or crane – such as from inside a waterfall – without having to sacrifice image quality.
The Shotover U1’s redundant battery system with on screen feedback of cell voltage and capacity allows the pilot to turn off a failed battery cell and get the ship home safely. The redundant flight control system provides operators with the ability to quickly switch to a back-up flight controller if the need arises. Additional features of the Shotover U1 include a user-friendly design that allows operators to easily swap cameras and lenses during a shoot, 10x more pan motor torque than other prosumer gimbals and a unique balancing system for unshakeable stability. Like all Shotover systems, the Shotover U1 has no ITAR restrictions, enabling it to be shipped around the world.

Julian has scripted some new enforcement, and I've installed the scripts
on the Perforce server. Now if you try to submit a .java file
containing tabs, or containing lines which end with spaces, or for which
the last line is not
// End YerFileName.java
you'll get an error describing the problem, and you'll be asked to
reattempt the submit after fixing it.
If you get any bogus rejects, please let us know and we'll fix the scripts.
The checking script is available in //open/util/bin/checkFile, and you
can run it locally if you need to (the diagnostics should be the same as
what the server spits back).
Mondrian currently has one file in violation; it'll need to be fixed as

iOS 5.1.1 Untethered Jailbreak to be Released Tomorrow
Pod2g’s recent iOS 5.1.1 untethered jailbreak update indicated that within a very short period the much awaited jailbreak was to be released. In fact a report even pointed out to the release being this Friday, that is the coming tomorrow.Pod2g had been working quite hard on the jailbreak and had managed to cover all the devices except for Apple TV 3. He had claimed that the iOS 5.1.1 untethered jailbreak release date was just a matter of days away. Now according to a recent post that corresponds to a previous one by pod2g, the iOS 5.1.1 untethered jailbreak is likely to be demonstrated live at the Hack InThe Box conference to take place in Amsterdam tomorrow. The demonstration is to be followed by its much anticipated release.
No Spam Guarantee
The news about the iOS 5.1.1 ubtethered jailbreak release tomorrow at the conference has also been confirmed by the official twitter account for the conference. The organizers are reportedly offering special 1-day passes for those who would want to witness the historical release.
Now about the timings of the conference and the following release,Amsterdamis 6 hours ahead of EST and the earliest we can witness the release would be at 3AM EST tomorrow. But one thing that seems to be weird is that the official agenda showing timings displays the event featuring for iOS 5.0.1 instead of for iOS 5.1.1. It could be that the agenda hadn’t been updated or there was a typing error.
According to posts, there will be the Corona Jailbreak event starting at 5:30 AM EST tomorrow followed by Absinthe jailbreak event at 7:00 AM EST. And those interested to be a part of the major event can go to the Okura hotel to buy the 1-day passes for a price of 699 EUR.

David Sifry of Technorati at O’Reilly Web 2.0 Expo
David Sifry of Technorati did a presentation on some of their blog stats today at Web 2.0. He came up with a few interesting tidbits:
- 22% of the top 100 most-linked sites are blogs (this is interesting when you consider it in relation to mainstream media).
- The single largest posting language is currently Japanese. 37% of all public posts use Japanese as a posting language (he noted that they do undercount French, Korean & Chinese)..
- A newcomer of the top ten posting languages is Farsi (which is interesting if you assume that these bloggers are in Iran).
- Blogs are getting less active. In May of 2006, 36% of all of Technorati’s tracked blogs were “active.” In March of 2007, 21% of all of their tracked blogs were “active.”

How to Find Lost or Missing AirPods & Case
Are your AirPods or AirPods Pro and case lost or missing? Luckily, you can use the "Find My" App on your Apple device or iCloud to see the last known location, even if offline or dead. Follow the step by step instructions below on how to hopefully find your lost AirPods.
AirPods and AirPods Pro can be located using the "Find My" app on your Apple device, or iCloud account. The only case that can be tracked without the AirPods inside are the AirPods Pro 2.
If at least one of the AirPods has battery and the case is open, you can "Play Sound" or "Find" the current location.
If AirPods are now offline or dead, you can view the last known location. You can also set it to "Mark as Lost" which will notify an Apple device user if they pick it up.
How to Track AirPods if Lost or Missing
You can attempt to locate your lost AirPods with Apple's "Find My" app, which is only available on Apple devices like iPhones. Here's how:
Step 1. Open the "Find My" app on your iPhone or Apple device.
Step 2. Go to "Devices", then pick your AirPods from the list. Sometimes you will only be able to pick the left or right earbud. Only the AirPods Pro 2 case can be chosen separately from the earbuds.
Step 3. After selecting your AirPods, you can either "Play Sound" or "Directions" to see a map to the location. If you are close enough, you can also find a "Find Nearby" option.
Step 4. If you still can't find your AirPods with the above methods, you can scroll down to "Mark as Lost" > "Activate". This option will notify any Apple user who picks it up and shares your contact information with them to return them.
Can you find AirPods if they are offline or dead?
Yes, you may be able to see the last known location of AirPods that are offline or dead using the "Find My" app on your iPhone, Apple device, or iCloud account. To see the current location, the AirPods need to have battery and the case must be opened. As a last resort, you can also activate "Mark as Lost" inside the app, and hope whoever finds your AirPods has an iPhone and returns them.
How far can AirPods be tracked by location?
AirPods can be tracked within up to 40 feet (or 10 meters) of the last device they were actively connected to. This is the range of Bluetooth that can reach AirPods. If the AirPods are within this range, their location can be tracked and shared using the "Find My" app on iPhones and Apple devices.
What to do if you only lose one AirPod or the case?
If you only lose one AirPod or the charging case, you can buy a replacement for either of these online on Amazon or eBay. You will just need to perform a factory reset to your AirPods to get the new earbuds and case working together. Replacing just one AirPod or the charging case is an economical solution, rather than throwing away the whole product.

Thanks to the versatility of automatic parking systems, we are able to adapt our systems to existing spaces and structures. We have several automatic parking solutions but basically the operation of the same consists in leaving the vehicle on special metal platforms that will pick it up and in the available spaces. The advantages of these structures lie in the fact that, even in minimal spaces, it will be possible to arrange numerous cars with very short entry and exit times.
The triaxial platform system is the ideal system to park your cars automatically on different levels. Cars will be parked and sorted on different levels without the use of driving lanes or access ramps.
The available parking space can be used more effectively. Costs and at the same time increasing the number of parking spaces available. In addition to the economic benefits, this automatic parking system offers a high level of safety and has a positive impact on the protection of the environment thanks to the reduction of carbon dioxide emissions emitted by circulating cars in search of a place to park.
Each system has an access room equipped with equipment for detecting the size of the car stored in it and an RFID reading system to be used when storing and collecting your car. One or more vertical elevators act as a means of transport for the cars between the various levels that make up the system. The movement of the cars on the single level takes place through longitudinal and transverse movements; the management software also moves the cars outside normal work cycles in order to optimize the exit times of the cars, the software can also be supplied with the exit booking system of your car, made via the web.


A slick, clean hull at all times, with no need for haul-out
The Hulltimo Pro consists of an underwater robot plus a handheld control panel.
Thanks to its slightly positive buoyancy, the Hulltimo Pro hugs the hull using the suction generated by the rotation of the brushes under the machine.
The unit features four belt-driven wheels which provide excellent mobility on all types of surfacing. An on-board camera allows the operator to monitor the progress of the underwater cleaning operation.
There is no risk of damage to the hull. Debris is collected and filtered via a disposable bag built into the Hulltimo Pro.
The Hulltimo Smart consists of a very low voltage brush unit and a set of five boom elements. It is controlled by the operator who moves it across the underwater surface to be cleaned.
Its self-attaching function allows it to effortlessly hug the hull. The Hulltimo Smart's two side wheels ensure optimal access to even in the most difficult-to-reach areas.
The robot's built-in disposable bag collects and filters the debris detached by the rotary brushes.


If you want to become a systems thinker and achieve deeper insights about our complex world, you’re going to need a range of systems thinking tools.
But you might be overwhelmed by the sheer number and range of tools out there. You’ve probably seen a number of systems thinking toolboxes online. Some focus only on engaging stakeholders while others just cover mapping tools or systems thinking concepts.
This blog provides a comprehensive list of 75 essential systems thinking tools helpfully sorted into 10 categories.
For each tool I’ve created a short description. This will help you choose the right tool for the right purpose at the right time.
Linking to the best systems thinking tools and resources
When relevant, I link to the best place on the web to either get the tool itself or read a more in-depth description.
If you’re interested in learning how to use these tools, check out my online course all about how to solve complex social problems.
75 systems thinking tools in 10 categories
Instead of sorting through all the systems thinking tools, you can just jump to the category that best fits what you’re trying to do by clicking one of the sections below.
- Types of system problems (4)
- Types of system dynamics and system archetypes (16)
- Mental models and metaphors about systems (4)
- Concepts about systems (13)
- Mapping and visualizing systems (16)
- Brainstorming and engaging with stakeholders (7)
- Decision-making tools (6)
- Evaluation tools (6)
- Simulation and learning experiences (2)
- The ultimate multipurpose tool (1)
Why use systems thinking tools?
In a word, sense-making. Systems thinking tools help make sense of situations that are complex and hard to understand.
Sometimes the tool is a helpful mental model or concept that succinctly captures a dynamic otherwise hard to describe. On other occasions, for example, a tool may create a visual that better describes a system than words alone. Finally, tools may be about helping others see the systems they are operating within.
But just like any other tool, systems thinking tools extend your ability to modify the surrounding environment. By helping you better understand your environment, you’ll be better prepared to influence it in the way you want.
If you’re operating in a system – and it’s likely you are – becoming familiar with the tools below can enhance your complex problem-solving ability. That means you’re more likely to solve system problems and create the long-term impact you want.
Chapter 1: Types of system problems
It is important to recognize the type of systems problem you face because it has implications for how you should approach it.
#1. Mess: Coined by Ackoff in 1974, a mess is not just one problem, but a system of interrelated problems. The related insight, according to Ackoff, is that “the sum of the optimal solutions to each component problem taken separately is no an optimal solution to the mess.”
#2. Wicked problems: Introduced by C. West Churchman in 1967, a wicked problem is one where the information required to solve it depends on problem understanding. Rittel and Webber have aptly described the impossible implication: “in order to describe a wicked-problem in sufficient detail, one has to develop an exhaustive inventory of all conceivable solutions ahead of time.”
#3. Swamps: Developed by Schon, a swamp implies leaving the “high ground” of using research-based theory and techniques, and the necessity of using less rigorous techniques for swampy “low land” problems that don’t have a technical solution.
#4. Problematique (meta-problem): Introduced by Ozbekhan in 1970, a problematique is a system of messes. This is particularly apt for social problems in our society that are so interrelated as to be impossible to discuss in isolation.
Chapter 2: Types of dynamics and archetypes within systems
Recognizing basic variable relationships, as well as how they add up to common dynamics can help you more quickly see a system.
There are two basic types of causal loops: reinforcing (#4) and balancing (#5).
#5. Reinforcing feedback loops: Two variables change in the same direction, resulting in a compounding or exponential effect over time. An increase in X increases Y, which in turn increase X. Or, a decrease in X decreases Y, which in turn decreases X.
#6. Balancing feedback loops: Two variables change in opposite directions, often resulting in a plateau. An increase in X decreases Y, which decreases X.
#7. Time delays: The time between an action and the change(s) it manifests. Time delays often result in oscillations or inertia in system dynamics. In causal loop diagrams, delays are represented by two hash marks on any relational arrow.
#8. Unintended consequences: Outcomes of purposeful action not intended or foreseen. The law of unintended consequences is an adage used to describe the likely unintended (and undesirable) consequences of any kind of intervention in complex systems.
Systems dynamics was an approach developed in the 1950s by Jay Wright Forrester. Problems and systems are represented by causal loop diagrams (#43), which is a simple map of the system, component parts and relationships. Systems archetypes, which built on the work of Forrrester and John Sterman, were first catalogued as described below by Peter Senge in The Fifth Discipline (and added to by Donella Meadows and David Peter Stroh).
Below are the twelve most common system structures or patterns. In this case, I’ve found that a dozen causal loop diagrams can be overwhelming for most people. As such, I’ve only used short descriptions and common examples because they seem to be easier for most people to quickly digest.
#9. Balancing with delay: Response to action is delayed. If the delay is not understood by participants, action may under- or over-shoot the necessary amount to reach goals. Common example is supply chains where delays result in large inventory fluctuations.
#10. Limits to growth (or unanticipated constraints): A reinforcing feedback loop that leads to exponential growth until a system limit is reached. Continued action that had previously resulted in growth will not work and perhaps cause the opposite effect. Common example is learning a new skill.
#11. Shifting the burden (or unintended dependency): The symptom is addressed with short-term solutions to some effect, but the long-term cause of the problem isn’t remedied and likely gets worse. Common example is paying debts with more loans.
#12. Shifting the burden to the intervenor: Similar to shifting the burden, this version uses outside intervenors to successfully address symptoms, preventing system participant from feeling agency to address causes themselves. Common example is hiring outside consultants rather than learning in-house.
#13. Success to the successful (or winner takes all): A process by which a winner’s gains lead to more gains, and a loser’s losses leads to more losses. Common example is two products competing in the same company, where initial success of one product leads to more resources, which propels further growth over the other product.
#14. Accidental adversaries: Two parties who may be working for the same goal, but inadvertently become enemies, hurting their individual and collective chance at success. Common example is two non-profits with the same goals undercutting each other’s work in the pursuit of additional funding.
#15. Drifting/eroding goals (or unintended poor performance): Current pressures lead system participants to lower standards or goals, leading to deteriorating performance over time. Common example is federal budget deficit.
#16. Competing goals: Conflicting goals that are not possible to simultaneously reach, or too many goals that result in not achieving any of them. Common example is a strategic plan with over a dozen goals that no one can remember.
#17. Escalation: Two parties acting in a perceived zero-sum game where they see their welfare as dependent on their advantage over the other. Results in cycles of ever-increasing threat and aggression. Common example is gang warfare.
#18. Tragedy of the commons: A common resource is depleted by individuals seeking their own gain. A decreasing resource supply or diminishing returns leads to intensified efforts, perhaps fully using up the resource. Common example is mining a natural resource.
#19. Fixes that fail (or unintended consequences): An effective short-term fix creates unforeseen, longer-term consequences that require even more of the same fix. Common example is delaying maintenance, creating more expensive repairs in the future.
#20. Growth and underinvestment (or self-created limits): Continued growth requires significant investment in longer-term capacity that may hurt current performance. To maintain current performance, underinvestment is justified, but growth nonetheless slows due to lack of capacity. Common example is over-investing in advertising while underinvesting in human capital, resulting in a sub-par product and eventually lower sales.
Chapter 3: Mental models and metaphors about systems
These are the four most common metaphors about systems, and they are often used as systems thinking tools in systems change initiatives (learn more in my No-Bullshit Systems Change Guide).
#21. Iceberg: The iceberg metaphor is meant to show that we can’t see most of a situation’s causes. So, while we focus on real-time events, which is the tip of the iceberg, more foundational causes lie beneath the surface of our consciousness. The model encourages people to look at things “below water” like patterns, beliefs, power dynamics and mindsets.
#22. Root causes: The root causes metaphor is all about finding a condition’s initiating cause. Similar to the iceberg metaphor, what is above ground (the leaves) are obvious, whereas the less obvious cause is unseen below (the roots). The purpose of this metaphor is to get people to distinguish between symptoms and causes.
#23. Swimming in water: Just like the fish who doesn’t know what water is, in this analogy the the philanthropic sector is “swimming” in a system of non-explicit factors that nonetheless drive social change. It is posited that by focusing on non-obvious factors, practitioners can increase their odds of success. Check out The Water of Systems Change for a whole report based on this metaphor.
#24. Bathtub: The bathtub analogy is a simple way of describing any stock and flow system. The water is the stock, and the flows are controlled by the faucet (in-flow) and drain (out-flow). The purpose of this system map is to help people go beyond quantity at any given moment, and expand to consider rates of change.
Chapter 4: Concepts about systems
#25. Emergence: Most simply, the whole is more than the sum of its parts. Specifically, denotes properties of the whole (its structure or activities) not reducible to components.
#26. Self-organization: The principle that order emerges of out initially independent and uncoordinated components. Implies that trying to manage or control systems is difficult due to its own dynamics.
#27. Interconnectedness: The general everything is connected to everything else, like an ecosystem.
#28. Hierarchy: Parts are treated as wholes, which are themselves made up of smaller parts, which are themselves wholes. Higher “levels” are more complex and have emergent behavior not present at lower levels.
#29. Darkness: The idea that no complex system can be completely known, because each human has limited perceptions. Implies the need for multiple perspectives.
#30. Complimentarity: Coined by Neils Bohr, this term refers to the idea that no single perspective of a system can provide complete knowledge about the system. Similar to darkness (#29), implies the need for multiple perspectives.
#31. Equifinality: No matter the starting point, all actions lead to the same end point. Implies that some actions will have the same effect regardless of initial state.
#32. Multifinality: The same starting points will have dissimilar end points. Implies that some actions may result in different effects even given the same initial state.
#33. Requisite saliency: The idea that the parts of a system don’t have equal importance or relevance, but that these factors can only be determined through a process of examination and comparison.
#34. Requisite parsimony: Humans have a limit to the number of things they can process simultaneously, likely between 5 and 9 observations. From Miller’s famous The Magical Number Seven, Plus of Minus Two.
#35. Suboptimization: The optimal solution to a mess (a collection of interrelated problems), is not the sum of optimal solutions to each component problem. Attributed to a World War II observation by Charles Hitch.
#36. Synthesis: The opposite of reductive analysis, synthesis brings two or more ideas together to understand the whole in a different way than treating the parts separately.
#37. Satisficing: Because humans have incomplete information (a far cry from the “perfect information” presumed by traditional economics), they make the best possible choice at any given time based on what satifies their goals to a suffient degree. Coined by Herbert Simon, the word satisfice is a portmanteau of satisfy and suffice.
Chapter 5: Mapping or visualizing systems
This section categorizes mapping tools under brainstorming, hypothesizing, and simulating.
Mapping as brainstorming
#38. Rich pictures: Originally developed as part of Soft Systems Methodology by Peter Checkland, rich pictures is an individual or group method of creating a visual representation of an ill-defined or complex situation. The purpose is not to define the problem structure or logic model (unlike some of the mapping tools below), but to actively reflect on various perspectives about the situation.
#39. Cognitive mapping: Cognitive mapping is a method of creating a visual representation of a concept or process. Concepts are connected with arrows and linking phrases like “increases”, “causes”, or “is a part of”. Cognitive mapping has been used in Strategic Options Development and Analysis (SODA), where operational research (OR) interviews mappers and facilitates group processes to learn from the map. Mind mapping can be similar but instead of a free-form map it typically uses a tree structure. There are many concept- and mind-mapping software options.
#40. Connection circles: A brainstorming exercise to help people get started thinking about how variables are related. A circle is drawn and variables are listed on the outside. Participants then begin connecting variables with lines that go through the circle. This method can help identify closed loops that can be converted into causal loop diagrams.
Mapping as hypothesizing and representing complexity
#41. Behavior over time graph: A simple line graph that shows a variable’s change over time. Plotting multiple variables at the same time can help participants theorize about causal relationships between variables.
#42. Graphical function diagram: Similar to behavior over time graphs (see #41) in that two variables are being graphed, but in this version time is removed and the relationship between variables is charted. One variable is on the X axis and the other on the Y. The resulting graph hypothesizes the causal relationship between variables.
#43. Causal loop diagram: A diagram that visually shows how a set of variables are causally related, usually denoted by a increasing (positive) or decreasing (negative) relationships. This type of diagram focuses most on closed loops that are labeled as reinforcing or balancing. Causal loop diagrams are especially useful for identifying common system dynamics, or archetypes (see tools #9 through #20).
#44. Bayesian belief networks: A probabilistic visual representation of relationships that can be used in network analysis to determine probabilities. Often used in social network analysis.
#45. GIGA-maps: A mapping process that emerged from how designers apply systems thinking, GIGA-mapping attempts to create extensive visual maps that transcend traditional boundaries of boundaries and scale. Designers have used GIGA-mapping as a research tool to investigate design questions, as well as to create new knowledge.
#46. Viable systems model (VSM): Developed by operations researcher Stafford Beer, VSM models the organizational structure on any autonomous system capable of adapting itself to a changing environment. A key feature of all viable systems is that they are recursive.
#47. Social network analysis (SNA): A process of exploring and visualizing social structures using network and graph theory. Many different types of SNA software are able to analyze networks for key metrics like degree centrality, betweenness centrality, and closeness centrality. In addition to data analysis, visual representations provide avenues for qualitative analysis not otherwise available. There are many options of social analysis software.
#48. Policy structure diagram: A visual representation of steps in a decision-making processes. The map can be expanded by adding the factors that are weighed for each step.
Mapping as simulating
#49. Fuzzy cognitive mapping (FCM): FCM is a type of cognitive mapping that quantifies relationships between concepts with fuzzy logic, and allows the creation of simulation models to determine strength of impact. It is an excellent qualitative tool that combines the benefits of concept mapping with the empirical side of system dynamics.
#50. System dynamics simulation model: A computerized model that quantifies relationships and can measure stock and flows, analyze feedback loops, and run scenarios. This is a great option when there is an abundance of empirical data and all nodes can be quantified.
#51. Stock and flow diagram: Stock and flow is a way of representing quantities and rates in a more detailed way than in a causal loop diagram. Oftentimes people will start with a causal loop diagram and convert it into a stock and flow diagram by adding relevant quantities and rates.
#52. Discrete-event simulation: A way to model a system as a series of discrete events in time. Events occur at specific moments in time and result in state changes for the system. This type of simulation is particularly helpful in understanding complex behavior in processes, like in manufacturing and supply chains.
#53. Agent-based modeling: A computational model for understanding the behavior of independent agents and how their decisions result in aggregate, or system-wide behavior. This type of model is often used to re-create and/or predict how micro-scale behavior results in macro-scale behavior.
Chapter 6: Brainstorming and engaging with stakeholders
#54. Double-Q (QQ) diagram: A modified “fishbone” diagram of cause and effect that separates “hard” (quantitative) variables from “soft” (qualitative) variables.
#55. Actor mapping: A visual way to brainstorm or represent stakeholders who are involved with or influence an issue. Distinct from stakeholder analysis, actor mapping helps to depict the many relationships between stakeholder to explore relational dynamics in a system.
FSG has the best step-by-by resources for engaging stakeholders with the following group mapping methods. These methods are good for brainstorming, exploring issues in groups, and finding common understanding. However, most mapping and visualizing methods listed above are far superior in terms of mapping actual system structures and dynamics.
#56. Appreciative inquiry: A method for helping a group of stakeholders find or create a common vision. Unlike other methods that may focus on problems, appreciative inquiry takes a positive, strengths-based approach that builds on successes that already exist within a system.
#57. Ecocycle mapping: A collaborative activity and mapping process that applies a 4-stage (development, conservation, destruction, and renewal) closed-loop system to a particular initiative or organization. The insight being explored is how an organization’s work may, like a natural ecosystem, go through life stages over time.
#58. Timeline mapping: A process for creating a visual and chronological map of events, actions, achievements over time. The purpose is to put an initiative’s or organization’s work into a broader context of how it is affected by external events.
#59. Trend mapping: A group process for brainstorming trends related to any given topic. Like timeline mapping, the purpose is to consider the broader context of system changes over time.
#60. World cafe method: A methodology for facilitating collaborative conversation and hosting large group dialogue.
Chapter 7: Decision-making tools
#61. Fundamental objectives hierarchy: A way of decomposing and organizing objectives that clarifies which are most important and which are a simply a means to another objective. The hierarchy is created by asking series of questions to clarify what is valued most. Often used in conjunction with means-end network.
#62. Means-end network: Usually created from a Fundamental Objectives Hierarchy, a means-end network is a way of organizing how objectives can be achieved.
#63. Cynefin framework: A conceptual framework for analyzing general behavior of a system and a guide for decision-making. It provides “sense-making” for five different types of system environments: obvious, complicated, complex, chaotic, and disorder.
#64. Stacey matrix: A two by two matrix to help categorize actions or tasks based on level of complexity. On one axis is a scale of agreement from “close to” and “far from”. On the other axis is a scale of certainty from “close to” to “far from”. Within the matrix are five areas very similar to the Cyfin framework: simple, complicated (2), complex and chaos.
#65. Ladder of inference: A visual representation of steps one goes through, often without realizing it, to get from a fact to a decision. The original concept of each step depicted as a rung on a ladder was created by Chris Argyris. The tool is often used to help people think about how they think, and to share their thinking process with others.
#66. Force field diagram: Created by social psychologist Kurt Lewin, a force field diagram represents situations in which forces that drive change are in equilibrium with forces that resist change. For a change to occur, it is hypothesized, driving forces must be increased and resisting forces must be decreased. Like the ladder of inference, this tool helps people explain their thinking about why they made a decision.
Chapter 8: Evaluation tools
#67. 5Rs framework: Used by USAID to assessing local systems and the effectiveness of programs, the framework focuses on the key aspect of any system: Results, Roles, Relationships, Rules and Resources. The tool is used as a lens in evaluation to see the system “as is” and to envision desired changes (the system “to be”).
#68. Theory of change: A method and comprehensive description of how actions lead to desired results. Organizations and programs often use the tool to brainstorm desired long-term outcomes and work backwards to identify the conditions that must exist to create those outcomes. While an excellent logic tool, its linear progression can be limiting in complex situations in which change is less straightforward.
#69. Logic model: Often used in program planning, the tool hypothesizes a logical sequence of what an intervention’s outcomes will be. Like the theory of change, logic models are often used to focus on desired outcomes and move backward to actions.
#70. After action review: A structured process for analyzing what happened, why, and how it can be done better in the future. An excellent learning tool to explore intended results versus actual results achieved.
#71. Outcome harvesting: A highly participatory evaluation approach that looks at what has changed and works backward to determine if or how an intervention contributed to the result. The approach is used in complex situations in which in is not possible to prescribe in advance what a program’s interventions or outcomes will be. Learn more at Better Evaluation or in Ricardo Wilson-Grau and
Heather Britt’s book.
#72. Critical systems heuristics (CSH): A framework of twelve questions, developed by Werner Ulrich and later enhanced with Martin Reynolds, to surface judgements of boundaries in any system. CSH is an evaluation tool that questions perspectives about means and ends by asking “what is” and “what should be”.
Chapter 9: Simulation and learning experiences
#73. Management flight simulator: A learning environment that provides participants with experiential and conceptual lessons based on simulated real-world situations. Time is usually compressed so that participants can see the long-term consequences of their actions. Often used as training for corporate managers (or in high-school economics courses), the most classic example is the Beer Game. The best resource to play simulations online is MIT Sloan.
#74. Learning laboratories: Workshops that combine instruction in systems thinking with repeated use of games and/or management flight simulators. The intent is to encourage reflection about one’s own role in systems with double-loop learning.
Chapter 10: The ultimate multipurpose systems thinking tool
#75. Your brain: Yup, that’s right. Your brain is a complex problem-solving machine. Don’t forget that systems thinking tools themselves can’t provide you with the answers. And, tools can even serve to magnify your own biases if you’re not careful. No matter what tools you use, your job is to be a critical systems thinker in search of reasonable conclusions.

Let's continue last POSIX archiving guide from the
very spot we finished. Today, we'll deal with just one tool. Very peculiar one, because it's more of a development
utility than an archiver with portable format. In fact, it doesn't have a defined format at all. More than that, POSIX
acknowledges that several incompatible formats are known and that they don't care. User can usually count on one
implementation to support archives created on another machine using the same implementation, so it's not that bad.
It's time to stop pretending that ar
does not exist and learn how to use it.
Now then, when exactly do we want to use ar? Luckily, that's simple to answer. ar is used to create
libraries of object files that are meant to be later linked against. In other words, it creates static libraries.
In order to do it, ar maintains a symbol table. As long as at least one of the archived files is an object file,
ar is obliged to do it completely automatically. However, usability of the archive for the linker is only
guaranteed if all of the files are objects.
To create an empty archive:
$ ar -r archive.a
Now, that's not very useful. Luckily for us, option
-r actually means "replace or add" and accepts any
number of paths after the archive name:
$ ar -r archive.a file_a.o file_b.o ../../file_c.o
Assuming, that all of these files are present, they'll all be added to a new archive. If the archive.a already
happens to exist, then files that are already occurring in it will get replaced. If not, then files will get appended.
To list contents of the symbol table, so the contents of the archive, use:
$ ar -t archive.a
Nice! Notice, that the file_c.o was added directly, without any additional path - just basename of the file.
This will happen to every single file added to the archive. While adding files with same names you need to be cautious
about it. Consider modifying our archive.a by:
$ echo "Aloha!" > ../file_c.o
$ ar -r archive.a ../file_c.o
This will overwrite our current file_c.o with one that says "Aloha!". This could be problematic, but it's
generally easy to avoid and there are additional options that allow to do some shenanigans with the archive. Refer to
your friendly manual or standard itself.
You probably won't need to extract files from the archive, simply because you put it together so that the linker uses
it and not yourself, usually in a variation of one of the following ways. All depending on what tool is used as linker
and if the archive is available to it through its search paths:
$ cc -l:archive.a main.o -o main
$ ld main.o archive.a -o main
Still, if you need to extract files, you can extract them from library in two ways. First one uses
$ ar -x archive.a
This simply extracts all of the files from the archive directly into current directory. Keep in mind that the paths
are not remembered, only the basenames are. Using those basenames you can also extract selected files from the archive:
$ ar -x archive.a file_c.o
$ cat file_c.o
The other way of extracting is closer to cpio. By using
-p option content of selected files or
the entire archive will be printed out to standard output:
$ ar -p archive.a file_c.o
Just note that if you specify multiple files to output, they will get concatenated.
And that's about it regarding basic ar usage. Quite a few sources will probably recommend that you always run
-s option in every single operation you perform, in order to regenerate symbol table. However, that's not
required at all, ar should be able to deal with it without any input from the user. The only case in which it is
actually viable is after the archive was stripped. Otherwise, this suggestion is almost always useless.
If you are interested in precise management, then there are couple of options that will help i.a.,
-u for restricted updates, or
-p for unchecked appending. But again, in normal
usage, you probably won't need them as
-r will deal with almost anything a Makefile will need.


For the first time in the blockchain world, a Grammy award-winning band will use crypto coin tokens to distribute unpublished material.
The Grammy-winning American pop-rock band, „Portugal. The Man“, has launched a crypto-currency for its fans on the Ethereum-based platform, Rally Network. Known as PTM Coin, the new currency will grant fans exclusive access to various events and benefits, such as a live party, new songs and more.
Gnosis receives 2.3 billion dollars in Ethereum in one day, now it is the third largest ETH holder with 2.2% of the supply
Fanatical tokens emerged as a growing trend in 2020, allowing artists and content creators (and even football players) to establish virtual communities through token economies in a chain of blocks.
When Portugal. The Man launches an archive of previously unreleased performances for token holders this Friday, it will be the first time that Grammy award-winning artists will use cryptomoney to distribute new material.
Argentina’s River Plate club joins Sorare with its own collectible tokens
Portugal. The Man is known for its hit 2017 single „Feel It Still“, which is estimated to have sold 5 million copies in the United States and millions more worldwide. The band was formed by Alaskan natives John Gourley, Zach Carothers, Kyle O’Quin, Zoe Manville, Jason Sechrist and Eric Howk, who now reside in Portland, Oregon.
PTM Coin is hosted on the Rally Network, a digital asset platform built on an Ethereum side-chain that allows artists and content creators to build custom „Creator Coins“.
Binance launches trading and staking for three new Chiliz fan tokens
John Gourlay, lead singer from Portugal. The man, said that the decision to launch a crypt coin for his fans was motivated by a desire to encourage the growth of the community, while at the same time conferring ownership to the fans themselves:
„PTM has always tried to have a direct connection with our audience. We never felt good about charging for Meet & Greets or autograph signings and things like that, we looked for a solution that would allow us to welcome our community, but also give them the opportunity to experience real ownership of what we are doing.
Kevin Chou, co-founder of Rally, said the launch of PTM Coin was „the most substantial release of an artist’s social token“ in the crypto coin space to date and „the first time a world-renowned group has partnered with its community to offer live, unreleased recordings.
deadmau5 and Sutu collaborate to launch an audio-reactive non-expendable token in SuperRare
The concept of tokens for fans based on blockchain was imposed worldwide in 2020. European football giant F.C Barcelona began experimenting with the social token model in June, leading to a token sale of USD 1.3 million that sold out in just two hours.

ERPNext is a modern solution that is primarily involved with small and medium businesses. It is gaining traction in the industry as a no-nonsense, cost-effective ERP software.
ERPNext Point of Sale is compatible with both offline and online transactions, and synching is enabled by default. You may also define dimensions for each of your retail outlets. In fact, you may compare each outlet's P&L statement as well! You must follow a few procedures to set up POS, which is where this blog comes in handy.
ERPNext’s 5 Step Point Of Sale
Step 1: Setup Your Inventory
The Stock module in ERPNext allows you to integrate your inventory and performs automatic stock ledger posting. In the Stock Settings, make sure that the perpetual inventory setting is turned on.
Step 2: Add Item Prices
Item Price allows you to set the prices of your products. You may have one or more Price Lists based on multi-currency, branch-specific product offerings, and other factors.
Step 3: Configure POS Profile
You'll need to make a Point of Sale Profile now. For each retail outlet, you can create several profiles. One or more users can be included in a single POS Profile. Cashiers have the ability to create Cash Closing Vouchers as well.
Step 4: Open POS
4.1 - Type "POS" into the awesome bar, and "Open POS" will appear as a suggestion. The POS screen appears once you pick it. You can choose the customer (one client can be defined as "Cash Sales/Branch Name").
4.2 - You can include the things that the buyer wants to purchase. There is a feature that allows you to navigate through the product list by Item Code, Item Name, Item Serial Number, or Barcode. You can also use a scanner to scan item barcodes or serial numbers.
4.3 - Then, to finish the deal, click the "Pay" option to pay for it with cash or a credit card (as per the setup of payment modes in POS Profile) If a customer has paid more than the outstanding balance, ERPNext calculates the difference automatically.
Step 5: Invoice your customer
In POS Profile, you can choose the default print format template for the system-generated POS Sales Invoice.
Other Features of ERPNext:
Offline POS: You can use Point of Sale when you're not connected to the internet. The system will synchronize the invoices once the internet connection is restored.
Configurable Print Formats: You may tailor your invoices according to your brand with the changeable print formats. Choose your style and generate print formats quickly and effortlessly with our drag-and-drop Print Format Builder.
Multi-store Management: With only a few clicks, you may register new branches of your firm and begin transacting right away! You can set up measurements for each branch or product line and analyze expenses, stock movements, earnings, and losses to determine your supermarket's overall profitability. With ERPNext's accounting dimensions, you can simply analyze store-specific P/L and income statements.

Feedburner’s superb BuzzBoost feature allows you to take one of your feeds and turn it into html for traditional web page applications. The BuzzBoost html has a ton of classes and IDs which allow you complete flexibility with how the html is presented. You can’t see all the IDs and classes by looking at the source html.
Using the WebDeveloper Firefox addin, you can see all the classes and IDs in the generated html. So if you want to delete the little Feedburner image that say’s “Headlines by Feedburner”, just add
display:none to the
#creditfooter ID. If you don’t want the “Subscribe to this Feed” output, just add

A couple of months ago, I wrote a small note about feeds. Well, Ronald over at the Reader Appreciation Project did a much better job than I did, plus he wrote a kickin’ WordPress plugin to help you style your self-hosted WordPress feed.
While you’re over there at the RAP, check out Ronald’s other superb plugins. I use his AJAX Comment Editing and Categories/Posts Site Map plugins as well. He gets a big +1.
From the Perspective of a Feed Reader » Reader Appreciation Project
One of the sacred oaths webmasters must hold is to protect their contributors’ email addresses. It’s easy for static web sites. Just don’t use the mailto: tag. However, it’s not so easy when you have a message board or a blog. Message boards and blogs generate feeds. One of the more popular feed types is RSS2 which features the optional ‘author’ tag. The RSS 2.0 Specification (RSS 2.0 at Harvard Law) requires the author’s email address to be included in the tag for proper validation. Hello to all the harvesters and goodbye to keeping email addresses secure.
If you use WordPress and RSS2, don’t worry. The RSS2 feeds for comments and posts use the preferred ‘dc:creator’ tag which doesn’t require the author’s email address to validate. If you are using another blogging platform, pull up your feed and view the source. If you see the ‘author’ tag, someone’s email address is floating out there. Not good.
I came across this issue when I was looking at the source feed for my SMF (version 1.1.1) message board. Sure enough, there was the ‘author’ tag and all the members had their email addresses hanging out there. Changing the default feed to RDF or even better, hacking the SMF feed generating code to remove the ‘author’ tag will secure your feed and keep it validated.
My favorite feed reader! I can’t seem to get the column widths to stick consistently but that’s the only problem I have running it in 10.3.9. The GUI is almost identical to Mail.app so there’s no learning curve.
Open Community: Vienna 2.2 Released
My primary machine is a mac. Firefox is my preferred browser when I’m working on html or WordPress because of the great add-ons which help me troubleshoot css. However, I do have access to a pc with IE7 and I have to say, the built in feed reader is really slick. Easier to use than the Live Bookmarking on Firefox IMO.
Mention Internet Explorer 6 to anyone who does web or blog development and the foul language starts to fly. IE6 presents rendering and development problems, especially on blogs. The theme on my self hosted blog has a separate style sheet with workarounds so the blog doesn’t look like a jumbled mess in IE6. Still, we wait for the day when the last user ditches IE6 for Firefox, Safari or even IE7. That day isn’t coming very soon according to the stats Matt shows in his blog.
Everyday, I look at the search terms that people use which somehow get them here. One of the searches was asking about how to read RSS feeds with Internet Explorer 6. My first thought was, “Ummm….don’t use IE6.” Of course, that’s my recommendation
but it appears that Lektora has a plugin which works with IE6. I don’t know why I’m telling you this but what the heck. I don’t know if it works, how it works or why you’d want to use it so caveat emptor. If you are steadfast in keeping IE6 alive, it’s an option. I’d rather you ‘browse happy!’
Photo Matt » Browser Stats
UPDATE September 12, 2007 – Since I wrote this, the Lektora site has been down. Letkora was purchased a couple of years ago so I’m not sure if this product will continue to be supported. If you want integrated RSS feeds in your web browser, try IE7. There’s always Google Reader, too.
When I first started to dabble in html and web development, I realized the power of external stylesheets. A minor change to one file and you can change an entire web site. Beautiful. Same for blogs. Then I discovered FeedBurner and it’s fantastic BuzzBoost feature which takes a feed and converts it to html for static web pages. Update my blog and my web site refreshes, carrying over the css classes and ids in the tags which is important when I have images in my blog. All’s well, right?
FeedBurner will tell you how many readers use IE 6.0 (ugh) and how many readers view your content in a feed reader. Unfortunately, you can’t use your own external css stylesheets to control how images are styled on a feed reader. Since I can’t ignore these readers, I will use inline CSS styling to provide some control of how my feed is presented. As an example, I like to float my images to the right on my blog since it uses a right sidebar. My stylesheet will take care of this on the blog but it won’t do anything for my feed so I will use inline css in the img tag to float the image to the right. It’s a little duplicitous but at least your feed (and browser-friendly FeedBurner page) will look ok.

Dionisio, M., Mendes, M., Fernandez, M., Nisi, V. & Nunes, N. (2022) Aqua: leveraging citizen science to enhance whale-watching activities and promote marine-biodiversity awareness.Sustainability, 14(21), 14203. DOI:10.3390/su142114203 (IF2022 3,9; Q3 Environmental Studies)
Life-supporting ecosystems are facing impending destruction. The human–computer interaction (HCI) community must rethink how to design technological interventions that reconcile concepts and theories for ecological computing. Proponents of sustainable HCI have pushed for tools and systems that aim to decenter the human in a shift toward posthuman design—a theoretical approach that challenges the assumption that only humans are stakeholders of technology as it increasingly shapes the future. Building on the iconic value of whales and the economic impact of whale watching as a form of ecotourism, we developed Aqua, a digital tool that leverages the potential of citizen science to engage tourists in marine-biodiversity awareness and conservation. This manuscript is advancing the field of sustainable HCI and tourism applications in two ways: first, we deliver an artifact contribution by designing and implementing a digital tool to enhance whale-watching activities. Second, we offer an empirical research contribution through observation and data gathering while comparing participants’ experiences of a whale-watching trip with and without the digital tool. Finally, preliminary insights are provided to inform the design of future digital tools aimed at promoting environmental conservation and citizen-science approaches among tourists. This work presents progression in understanding and informs the design of digital tools to engage tourists in novel and sustainable experiences.
