William Oughtred (1574-1660), the inventor of the slide rule, was Rector of Albury from 1608 or 1610 until his death. Here he tutored many young mathematicians of the time, including Wallis, Ward, Moore, Scarburgh and Wren; and all English mathematicians for the next century, including Isaac Newton, learned algebra from his Clavis mathematicae (1631). Seth Ward stayed here with Oughtred after his expulsion from Cambridge during the Civil War.

2- pyridone is a chemical compound from the group of nitrogen-containing heterocycles. Its structure is derived from that of pyridine. 2- pyridone belongs to the group of lactams, however, is in a tautomeric equilibrium with its lactim 2 -hydroxypyridine ( lactam lactim tautomerism ).
Production and representation
2- pyridone can be obtained by reaction of 2 -pyrone with ammonia, but there are other possibilities, for example, the synthesis of pyridine or Guareschi - Thorpe known condensation.
2- pyridone is a solid, which is in equilibrium with its tautomeric form (2- hydroxypyridine ) at room temperature.
The position of the equilibrium is dependent on the polarity of the solvent. In polar solvents such as water, the equilibrium is almost entirely due to the 2- pyridone side, while in non-polar solvents, preferably, the 2 -hydroxypyridine is present. In the gas phase the compound is predominantly in the lactim.
2- pyridone dimers formed by linking two molecules over relatively strong hydrogen bonds.
The dimeric structure is also present in the crystal. The dimer is similar to that occurring in the DNA base pair adenine - thymine.
2- pyridone, is used as an intermediate, catalyst or ligand for the preparation of drugs such as ciclopirox, levetiracetam and Amphenidon.

Grayscale-thermal tracking via inverse sparse representation-based collaborative encoding
2020-03-26T10:23:03Z (GMT) by
Grayscale-thermal tracking has attracted a great deal of attention due to its capability of fusing two different yet complementary target observations. Existing methods often consider extracting the discriminative target information and exploring the target correlation among different images as two separate issues, ignoring their interdependence. This may cause tracking drifts in challenging video pairs. This paper presents a collaborative encoding model called joint correlation and discriminant analysis based inver-sparse representation (JCDA-InvSR) to jointly encode the target candidates in the grayscale and thermal video sequences. In particular, we develop a multi-objective programming to integrate the feature selection and the multi-view correlation analysis into a unified optimization problem in JCDA-InvSR, which can simultaneously highlight the special characters of the grayscale and thermal targets through alternately optimizing two aspects: the target discrimination within a given image and the target correlation across different images. For robust grayscale-thermal tracking, we also incorporate the prior knowledge of target candidate codes into the SVM based target classifier to overcome the overfitting caused by limited training labels. Extensive experiments on GTOT and RGBT234 datasets illustrate the promising performance of our tracking framework.

As organizations, governments, and people’s lives continue to change as a result of technology, aspirant students are leaning more and more toward careers in computer science, programming, and application development. The abundance of professional opportunities in the computer sector, however, might make it challenging to select a job after college. The contrast between a web developer and a software developer might be particularly difficult for students to understand.
While those who are interested in these professions frequently seek degrees with a similar focus, like a Bachelor of Science in Computer Science, the knowledge and skills they develop during their studies usually differ. Despite the fact that both positions include writing code, creating client-side applications, and employing various programming languages, the projects they work on are typically very different.
Let’s take a closer look at the duties, employment outlook, and fundamental abilities required in each of these well-known tech professions in order to help you comprehend the differences between web development and software development.
Key Differences Between Web Developers and Software Developers
The main distinction between a web developer and a software developer is the applications they use and the products they strive to produce. While software developers are more focused on creating computer programs for desktop and mobile devices, web developers are primarily focused on creating websites and online applications that run in web browsers.
Both professions demand a lot of programming knowledge, a keen eye for detail, and a talent for problem-solving, but they have different maintenance needs, complexity levels, and work processes.
For instance, to make sure their company’s website is effective, user-friendly, and aesthetically beautiful, web developers frequently work closely with business and marketing specialists. On the other hand, software developers frequently collaborate with other technologically savvy colleagues on significant software, operating system, and mobile application initiatives that may not require involvement from other business divisions.
The job path students select should ultimately be in line with their professional objectives and personal interests, which is why it’s essential to thoroughly research each position before devoting the necessary time and resources.
Who is a Web Developer?
Apps and interactive websites are created by web developers. The building of a website may involve anything, from straightforward text files to intricate data processing.
What Does a Web Developer Do?
A web developer creates websites and webpages using coding. As independent contractors, web developers may provide their services to people or companies that require websites or web applications. Web developers can also work for a business, either by keeping up the online presence of that business or by working for an employer who subcontracts out web development tasks.
A web developer might perform the following roles:
- Front-end developer: These design professionals, often known as client-side developers, are in control of how websites and applications seem to users and perform. They are in charge of ensuring that all online information is simple to access, explore, and engage with, particularly for people with rudimentary computer skills. To avoid display and functionality issues, front-end web developers must also make sure their websites are compatible with a variety of operating systems, browsers, and devices.
- Back-end developer: These specialists concentrate on the technological elements of web pages and applications that support both fundamental and sophisticated functionality. They primarily focus on developing new APIs and user interfaces based on predetermined requirements for administrative components such as databases, website architecture, and application logic. Generally speaking, this type of developer is concerned with how websites and web-based applications work on a fundamental level.
Roles and Responsibilities of a Web Developer
Building interactive web sites requires the use of programming and markup languages by web developers. These pages might be as simple as text files that are accessible online or as complicated as e-commerce sites. Regardless of the final result, there is a good chance that it was produced by a web developer, at least partially, if not totally, if users are reading it through a web browser.
A web developer needs to take care of the following responsibilities:
- Create well designed, testable, and useful code
- Make website layout or user interface using basic HTML/CSS
- Combine data from multiple back-end services and databases
- Collect and improve specifications based on technical requirements
- Generate and maintain a software documentation
- Be accountable for maintaining, developing, and scaling the website
- Stay updated with emerging technologies and industry trends
- Work together with web designers to match up the visual design intent
Who is a Software Developer?
A software developer is someone who, as the name implies, is in charge of identifying, developing, installing, and testing software systems that they have created for a firm to provide infrastructure for millions of users and decrease security breaches for clients or users. They are only the innovative minds behind computer programs.

What Does a Software Developer Do?
A software developer creates and codes programs, either from scratch or in accordance with a design specification. Software developers can use a coding language to produce their software packages, or they can utilize a development engine that offers pre-built functionality or modules they can use. There are numerous work prospects for software engineers across a wide range of industries. Typical industries in which software developers may work include:
- Mobile applications: Applications made by a mobile software developer are tailored to function with the special features of mobile devices. Games, business-related apps, and applications for helping users finish their work are examples of this.
- Professional software: Many programmers are employed by businesses that produce and offer retail software solutions for business use. Professional software completes tasks and manages workloads for businesses, enabling them to operate more safely and productively.
- Video games: Working as a software developer on a game project enables you to use your coding expertise to design the systems that enable a video game to run and provide players with a satisfying experience.
Roles and Responsibilities of a Software Developer
For desktop and mobile platforms, software developers often produce programs and applications. The end users can interact with computer tools for a variety of activities and tasks thanks to the software they create. Additionally, they must to be fully conversant with both the idea of programming and the best development procedures.
A software developer needs a broad range of skills to take care of the following responsibilities:
- Design algorithms and flowcharts
- Deliver clean and useful code based on specifications
- Incorporate software components and third-party applications
- Validate and deploy programs and applications
- Troubleshoot, debug, and update existing software
- Gather and assess user feedback
- Propose and execute upgrades
- Generate technical documentation for referencing and reporting
Tips For Choosing Between These Careers
Consider the following advice while choosing between web development and software development if you’re thinking about a career in computer science:
- Choose a versatile major: Consider a degree like computer science that can be used for both, or during the first few semesters, concentrate on your electives and general computer science courses. This preserves your field of study possibilities while allowing you to advance toward a degree.
- Try both fields: Getting hands-on experience is one of the best ways to learn about software and web development. You can learn the fundamentals of both professions and decide which one appeals to you more with the help of free online courses.
- Establish your career goals: Make a list of your career objectives and rank the factors in it according to importance and preference. This will enable you to evaluate your job possibilities and decide which most closely matches your objectives.
- Apply for an internship: A great way to obtain expertise in software or web development is to participate in an internship program. An internship gives you the chance to test working in that sector and determine how much you enjoy it, in addition to giving you experience and recommendations that could aid you in finding employment after graduation.

Entity-Component-System (ECS) is a distributed and compositional architectural design pattern that is mostly used in game development. It enables flexible decoupling of domain-specific behaviour, which overcomes many of the drawbacks of traditional object-oriented inheritance.
Elixir is a dynamic, functional language built on top of the Erlang VM designed for building scalable and maintainable applications.
In this article, discover how we can use both ECS and Elixir in a novel approach to structure our programs beyond the class based inheritance paradigm.
Drawbacks of class-based inheritance
The traditional way to build game worlds is to have an object-oriented hierarchy of game objects that model the world. However, even simple objects can end up with a large set of unused functionality. Consider the example below:
We’re building a game engine, and we find ourselves with the below class hierarchy:
We have a base
GameObject, which is subclassed by
Animal is subclassed by
Whale, each with its own special behaviour
swim() respectively. We also have a
Killer Whale, which is a subclass of
Whale than can
Let’s try to introduce a new animal to our world:
Killer Bunnyto be able to
kill(), but which class should
Killer Bunnyinherit from?
For languages / platforms with only single inheritance, we’re out of luck. We’d have to move both
kill() to some superclass such as
Killer Bunny can then inherit. However, all other subclasses of
Animal will inherit things they don’t need.
kill(). Over time,
Animal will become a god object with a massive set of behaviours.
Multiple inheritance doesn’t do it either. Suppose
Killer Bunny inherits from both
Killer Bunny will inherit
swim(), which is unneeded functionality.
We face a number of other issues:
Rigid functionality: Only
Killer Whale can
kill(). We can’t change our mind later and make other animals
kill() very easily. Behaviour is only available to classes that were specifically coded to support that behaviour. As the number of game entities grow, we face greater difficulty in finding a spot in the hierarchy to place new entities under.
The Diamond Problem: The “diamond problem” (sometimes referred to as the “deadly diamond of death”) is an ambiguity that arises when two classes B and C inherit from A, and class D inherits from both B and C. If there is a method in A that B and C have overridden, and D does not override it, then which version of the method does D inherit: that of B, or that of C?
The Blob antipattern: With inheritance, games end up with a huge single root class or some other leaf node with a large amount of functionality. Subclasses become overburdened with unneeded functionality.
The difficulties mentioned above has plagued game developers for a long time, and Entity Component Systems attempts to remedy these annoyances. We’ll learn about ECS in the next section.
Entity Component Systems
There are three key abstractions in ECS:
We’ll examine each in detail, starting from
The qualities or aspects of an entity.
Components are minimal, reusable data objects that are plugged into entities to support some behaviour. A Component tags an entity with a single quality. A Component itself has no behaviour. Typically, it’s implemented as a struct or dictionary.
Imagine we have a
Bunny entity in our world:
We can define bunnies as nothing more than an aggregation / collection of independent components. In the example above, a Bunny is ‘composed’ of components such as
Each component support some behaviour. To illustrate,
Seeing has attributes
sight_radius to support a sight behaviour. Note however, that a Component themselves have no behaviour. Each component is simply a minimal data object.
An aggregation or container of components.
Entities are solely the sum of its components. Entities are implemented as a globally unique IDs associated to a collection of Components. Note that Entities themselves have no actual data or behaviour. Each Component gives an Entity data to support some behaviour.
Let’s look at our
See the dashed box around our components? That’s the
Bunny entity - nothing more than a container of components. We can define entities as an aggregation of any subset of components, like this
An entity is little more than a collection of components.
Some ECS implementations allow you to modify an entity’s components collection at runtime. This allows you to “mutate” entities on the fly. For example, we could have a
Poisonedcomponent that makes entities tagged with this component to lose health over time. We can add and remove this component dynamically to inflict and cure poison. You might also have a ‘blind’ status effect that removes the
Seeingcomponent of entities it hits.
Up until this point, we haven’t touched on any logic or behaviour. Entities are just an aggregation of components; Components are just data objects. Where does behaviour in ECS come from? They come from Systems.
Systems brings entities and components to life.
Systems enumerate over Components or groups of Components, updating their state according to an internal rule or external event. A way to think of Behaviour is as a change from one state to another. Let’s see an example:
Behaviour: “A bunny on a tree falls due to gravity.”
How do we implement the above behaviour? We can make it so that
Placeable Components with a
z value more than 0 to decrease over time to 0.
Behaviour: “Living beings age.”
How do we implement the above behaviour? We can make it so that
Living Components has its
age value increase over time.
We create a dedicated System for each behaviour we wish to support. A
GravitySystem enumerates over all
Placeable Components; a
TimeSystem enumarates over all
Living components. Bear in mind that Systems operate on Components, not Entities.
Data Flow in Entity-Component-System
To further cement your understanding of the pattern, let’s see a typical data flow in this architecture:
Each System listens to some event stream such as time or player input, and updates the states of its Components in response to that event and some internal rules. These continuously changing state is available for access by the Entities it is a part of, and thus result in behaviour.
Another example: Suppose the player presses the “move left” key. PlayerInputSystem executes and detects the keypress, updating the Motion component. MotionSystem executes and “sees” the Motion for the entity is to the left, applying a Physics force to the left. The RenderSystem executes and reads the current position of the entity, and draws it according to the Spatial definition (which may include texture region / animation information).
The spreadsheet analogy
Another way to think of ECS is as a relational table, like a spreadsheet:
An Entity Component System can be visualized as a table with columns of components and rows of entities. To operate on a single component, we select its column and look at each cell. To operate on an entity, we selects its row and look at each cell.
Advantages Of ECS
Now that we have a better understanding of the Entity-Component-System architecture, let’s think about how this approach compares to class-based inheritance.
Good decoupling, single responsibility principle: each behaviour or domain is decoupled from each other in independent components and/or systems. Unlike our monolithic god object in class based inheritance, we can extract any subset of functionality and assemble it in any combination. ECS also encourages small interfaces.
Composability and runtime object definition: Any type of game object can be created by adding the correct components to an entity. This can also allow the developer to easily add features of one type of object to another, without any dependency issues. For example, we can do
Entity.build([FlyingComponent, SeeingComponent]) at runtime.
Testable: Each component and system is a unit by definition. We can also substitute components with mocked or demo components for testing.
Parallelizable: In many real-world ECS implementations such as MMOs, a System is implemented as a distributed system or a worker pool that can distribute the work amongst themselves. This lets us horizontally scale the size of our simulations by increasing the number of system workers in our pool.
Separation of data and behaviour: components hold data, systems hold behaviour. There is no intermingling of the two. This property lets you plug-and-play different behaviour to apply on the same data.
Challenges Of ECS
Despite the flexibility this gives us, ECS introduces a number of non-trivial challenges:
ECS is a relatively unknown pattern: Since this design pattern has been mostly limited to game development, discussing how to use ECS for domains outside of it such as for building web apps can be challenging. There are few resources available for applying this pattern to other domains, if any.
Handling interprocess communication: How do we handle the communication between systems and components? We need some kind of message bus or publish-subscribe system to enable parts of our ECS to talk to each other. Depending on the language or platform the ECS is implemented in, this could introduce a spike in complexity. The cost of iterating through components and entities may also result in a drop in performance.
Inter-component communication: What happens when a system needs to access and modify data in multiple components? Components might need to share state with other components and communicate with each other prior to communicating with systems. For example, say we have a
Sound component in an entity. We could have a
PositionalSoundSystem that needs to communicate with both components. We may need a separate channel for inter-component communication to support this use case.
Inter-system communication: What happens when two systems need to access and modify the same component? Say we have two systems: one multiplies attribute
-1, the other adds
10. Depending on the order of application of the two systems, the end result will be different. Unless the operations are associative, we may need to introduce a way to ensure that the order of the systems are correct.
Not as concretely define as other design patterns such as MVC: There are a multitude of ways to implement ECS. Each language or platform will have different abstractions available, which result in different flavours of ECS.
ECS in the Real world
Aside from being a popular architecture for video games, current applications of ECS are for large-scale distributed simulations. This includes real-time city traffic, internet telecommunications network, and physics simulations. It’s also used for building massively multiplayer backends for video games with staggering numbers of entities.
One startup in particular, is building an ECS-as-a-service called SpatialOS.
An ECS implementation in Elixir
In this section, we’ll take a look at one possible implementation of Entity-Component-System in Elixir. I’ll start by briefly mentioning why Elixir (also Erlang) and its concurrency primitives is a good fit for the ECS pattern.
From here on out, since Elixir compiles to Erlang bytecode, when I say Elixir I also mean Erlang.
The Actor Model
One of the key abstractions of Elixir are processes - these are akin to actors of the actor model. Actors are computations entities that can:
- Send messages
- Receive messages
- Spawn new actors
In the diagram above, Actor
A sends messages
2 to Actor
C, which it receives. In response to these messages, Actor C can do send new messages, or spawn new actors and wait to receive messages from those actors.
Elixir also has higher-level abstractions for building actors called
Consider how you might implement ECS with the help of actors.
Here’s what our implementation would look like in use:
My ECS implementation in Elixir is open source on Github. You can clone and run it via
iex -S mix from the root folder. You must have Elixir installed on your machine.
An entity is a struct with a randoms string
id and a list of components. We can create entities and extend it by adding components. Both can be done at runtime.
Below is an actual entity, the
The above code introduces the idea of a ‘prefab’, which are convenient factories for entities with a common set of components. Using the prefab saves you from typing too much, and acts as a facade.
Component.Agent modules provide facilities to get and set state. Each Component is backed by an Actor (an Agent - a kind of GenServer.) Components such as
TimeComponent implement the
Component behaviour (interface.)
Below is an actual component, the
TimeComponent, which implements the
System and Registry
Systems enumerates over all components of its type.
A few things to notice:
dispatchtakes in an external action, evaluates it based on an internal rule, and returns a new state. This part was inspired largely by my experiences with Redux reducers and Elm’s
componentsmethod returns the set of components that this System will enumerate. Whenever a Component is instantiated, it registers its agent to the
Registrywhich keeps track of all active components. The Registry is itself an actor, shown below:
And that’s it!
This particular ECS implementation may be a bit rough around the edges. There are many flavours of ECS, and this is most certainly not the only way to make ECS work. Your feedback is most welcome!
ECS is an overlooked architectural pattern that overcomes some of the drawbacks of OOP-style inheritance, and is a great fit for distributed systems.
Branching out into unfamiliar domains (such as game development) is a fruitful source of new ideas and patterns to write better software.

Drivers don't stop working by date. So yes your driver will work. As time goes on they eventually will not have any more bug fixes, performance improvements or even support for future operating systems. Typically the later is way into the future. For instance my AM2 board is still supported and it is from 2004.

Overview of Molecule curation
Textpresso aided molecule curation
Extract drug terms and associated sentences from papers, automate the population of postgres with the extracted information. Extract drug terms using the following rules:
- only from sections: results, conclusion, discussion, non-sectioned
- use filters: -review[type]-anesthetized-anaesthetized-anesthetised-anaesthetised-immobilized-immobilised-receptor[sentence]
- Download drug (CHEMICAL) list from http://ctd.mdibl.org/downloads/;jsessionid=EB1439FEB0CFB6FBF5977BB176141A41#allchems
Using a list of terms from the CTD, use textpresso to flag papers containing the term or synonym of term, extract relevant sentence. Map drug term with a MeSH ID (need to use both column 1 and column 7 terms from the tsp. if no match, create list of drug terms with no MeSH ID Match MeSH ID with Molecule postgres MeSH ID if no match, enter MeSH ID ->MeSH/CTD or default textpresso term name ->Public Name textpresso term name different case ->synonym curator ->Michael\\ If MeSH ID match is found in postgres Match drug (case sensitive) with Postgres Public if no match, enter term as a synonym (pipe separated). Match WBPaperID with WBPaper entries associated with molecule term if no match, check WBPaper false field if no match in WBPaper false then enter paperID Enter sentence(s) in Textpresso sentence field (need to create) For each matched MeSH ID, enter synonyms in synonym field
Change to the OA ->add WBPaper false field
Change to the Molecule dumper ->Don't dump Michael curator fields
cron job to grab new ids/terms from ctd?
Problem for some drugs:
levamisole for slide mounting -> actually this can probably be ok
sucrose as in sucrose flotation and sucrose gradient can we create an exclusion list?
- pgid -autoassigned
- WBPaper -multiontology, does not need to be filled in
- Public name -big text field, common name used in paper '''make required'''
- Synonyms -big text field, any other names associated with the molecule
- Molecule use -big text field, enter its use, make sure to have a source noted in WBPaper or include a pers comm. in the field
- MeSH/CTD or default -molecules in acedb should be stored with their MeSH UID.
- when no MeSH ID is available, a WBMol ID is assigned (based on the pgid), which will eventually get replaced by the MeSH ID when available. Therefore periodic checks of the WBMolecules against other databases must be scheduled.
- Initially these WBMolIDs were only to be kept internally in Postgres but with the addition of SMMID's to our curation pipeline, molecules with links to SMMID will be collected that do not have MeSH IDs available and will need to be pushed to the website without them.
- Also, molecules entered through XREFs are not suppressed if they only have a WBMol ID, so these molecules will be on the site in relation to these other classes.
- When MeSH IDs are available, WBMol ID's need to be kept as synonyms so the molecule to phenotype mapping can be maintained.
- These Names are scripted to be used in URL constructions for MeSH and CTD database links. By suppressing WBMol_id's URLs to these database were not pushed out to the database. Now that WBMol_id's are not suppressed incorrect URLs will be made and will now have to be suppressed somehow. See jobs for molecule dumper on this page: molecule .ace dumper change made 7/7/11
- If a molecule needs to be created it is given a WBMol ID, which will need to be used as a synonym once a bona fide MeSH ID is avaible -e.g. move the WBMol ID from the default field to the synonym field--talk to the web team about only displaying the public name.
- CasRN -ID text field; assigned by CAS, can be used in multiple chemical databases including ChEMIDplus. A ChEMIDplus db line is generated using the CasRN in the .ace file.
- ChEBI_ID -text field; ID for ChEBI db
- Kegg compound -text field; accession number for KEGG compound db
- SMMID -text field; to link to SMMID DB -also need to change the dumper
- Curator - single ontology
- Remark -big text, not dumped
Two files need to be supplied for each upload:
- Molecule.ace made from karen/Molecule/dump_molecule_ace.pl
- database.ace static .ace also in karen/Molecule : this file contains all the database info for the chemical/small molecule database links, it needs to be manually edited whenever there are changes to the databases associated with molecule data.
During each upload a molecule.ace file will be made in citace by Wen. This file will contain all the molecule cross references from within the RNAi and Variation Phenotype curation, merging them with the molecule data from the molecule list.
What we mean by small molecule
- metabolite (primary and secondary)
- monomers or very small oligomers of nucleic acids, proteins, and polysaccharides
- "Large collections of small molecules (molecular weight about 600 or less), of similar or diverse nature which are used for high-throughput screening analysis of the gene function, protein interaction, cellular processing, biochemical pathways, or other chemical interactions." (from nlm.nih.gov and wikipedia)
- metabolites: precursors, intermediates, or end products of a metabolic pathway
- monomeric or very small oligomeric nucleic acids (not RNAi primers), e.g. ATP, ADP, cAMP, GTP, trinucleotide repeats??
- minerals, ions, salts
?Molecule Name ?Text Public_name ?Text Synonym ?Text DB_info Database ?Database ?Database_field ?Accession_number Gene_regulation Gene_regulator ?Gene_regulation XREF Molecule_regulator Affects_phenotype_of Variation ?Variation #Evidence Strain ?Strain #Evidence Transgene ?Transgene #Evidence RNAi ?RNAi #Evidence Corresponding changes in touched models ?Phenotype_info Affected_by Molecule ?Molecule #Evidence ?Gene_regulation Regulator Molecule_regulator ?Molecule XREF Gene_regulator #Boolean
- Name-> MeSH UID
- when no MeSH ID is available, a WBMol ID is assigned, which are based on the pgid.
- Changes in names will also need to be conveyed to other curators so they can change the name in their curation pipelines so cross-links from their small molecule curation attributes will be retained.
- Public name -> common name in elegans literature
- Synonym -> other names, how do we mine these from other DBs?
- DB_info -> links to entity in other database add following databases to database.ace
Molecules will be linked to genes based on their influence on gene activity altered by variation, overexpression, and RNAi-based knockdown.
Molecules will also be linked to genes through their influence on gene activity directly through gene regulation interactions.
Molecule IDs will be provided, when available, for the following databases:<br>
- Database "NLM_MeSH" "UID"
- Database "CTD" "ChemicalID"
- Database "ChemIDplus" ''using the CasRN''
- Database "ChEBI" "CHEBI_ID"
- Database "KEGG COMPOUND" "ACCESSION_NUMBER"
- Database "SMMID DB" ''will need to add a field to capture their ID''
Initially, we will be using MeSH UIDs, assigned by the NLM, as IDs for the molecules in our database. Due to the more comprehensive coverage of the NLM molecules, and the fact that it is more stably funded, this source was thought to be a good starting point for this project. The list we are starting with is a pared down list of molecules from the NLM, that was created by the Comparative Toxicogenomic Database (CTD), which contains over 130,000 terms. For each term, this list contains a term name, CTD ID, MeSH UID, and where available CAS Registry Numbers. Using the CasRNs, we extracted the ChEBI ID from the Chemical Entities of Biological Interest database entity list, where it existed, along with any KEGG Compound accession number.
A sample molecule.ace record:
Molecule : "C009687"
Database "NLM_MeSH" "UID" "C009687"
Database "CTD" "ChemicalID" "C009687"
Database "ChemIDplus" "19545-26-7"
Database "ChEBI" "CHEBI_ID" "52289"
Database "KEGG COMPOUND" "ACCESSION_NUMBER" "C15181"
To make a working list of reference molecules for the various curation efforts, we used Textpresso to scan for all terms on the list that have been published in the C. elegans corpus. The resulting list is less than 6000 terms. The terms that have been identified in the corpus are available here:
http://textpresso-dev.caltech.edu/michael/molecule-obo-analysis/By-Frequency/ ''This is a directory of files of terms based on the number of times the term appears in the corpus.''
http://textpresso-dev.caltech.edu/michael/molecule-obo-analysis/By-Frequency/all ''This is a list of all terms from the previous files concatenated into one.''
This last file is being used as a starting file for molecule look-up by WB curators.
Caveats and notes:
- The list is now small enough that if we wanted to load it into WB at least we know that every term has some relevance to the literature (although unverified).
- The list is small enough to be amenable to editing through ontology editors like OBOedit (even though it is not an ontology).
- We do not have definitions of the terms, nor are the terms arranged in any hierarchical manner; however other databases do, and we provide links to those websites if an ID is available.
- Terms and synonyms of terms, will be added as needed, this curation effort still needs to be worked out, ideally the list will be incorporated as a selection list for whatever curation tool a curator is using.

[October 05, 2000] See the Sun Microsystems web site for description of the XMLspec DTD: "The XMLspec DTD was originally designed to be used to encode the XML specification document itself, even before the first XML processor existed! It was probably one of the first XML DTDs to be fully compliant with the XML specification, to be used in a collaborative authoring situation, and to drive the generation of multiple different outputs from the same source. Its scope soon grew to cover World Wide Web Consortium working drafts, notes, recommendations, and all other document types that fall under the category of 'technical reports,' and is in fact used by many W3C working groups and other specification authors. Eve Maler, now [2000-10] of Sun, took over the development and maintenance of the DTD in mid-1997, and revises it on a schedule mostly dictated by requests from W3C technical report editors. The latest versions of the DTD and its documentation, along with old versions, are officially published at the W3C site." See also the stylesheet.

The W3C 'spec-prod' development area stores a collection of doctypes and stylesheets that are used (by some W3C WGs) to produce working drafts and the various stages of recommendations.

Note of 12 Oct 2000: "As my initial foray into non-toy XML Schemas, I took a stab at creating an XML Schema for the XML Specification doctype. My goal was to write an XML Schema that was configurable in the same general way that Maler/Andaloussi-methodology DTDs are, and that would validate the same set of documents (modulo additional constraints that DTDs can't express). I'm sure I've overlooked things, possibly large things, but the schema at http://dev.w3.org/cvsweb/spec-prod/schema/ now validates the XML 2e Recommendation with XSV 1.166/1.77 of 2000/09/28 15:54:50." - Norm Walsh.

The W3C's XML Recommendation 1.0 (February 1998) and several related classes of W3C XML-related specifications documents have been produced in XML according to a formal document model expressed in an XML DTD. Such a DTD has been "developed for use with the XML family of W3C specifications. It is an XML-compliant DTD based in part on the TEI Lite and Sweb DTDs." Major contributors to the design of the DTD, as named, include: Jon Bosak, Sun (XML chair), Tim Bray, Textuality and Netscape (XML co-editor), Dan Connolly, W3C (W3C staff contact), Eve Maler, ArborText (DTD maintainer), Gavin Nicol, Inso (DOM member), C. Michael Sperberg-McQueen, University of Illinois (XML co-editor), and Lauren Wood, SoftQuad (DOM chair). The W3C XML DTD is subject to minor change as the W3C's documentation requirements are refined. This "XML specification DTD" has been documented in an accompanying commentary, Design Report for the W3C XML Specification DTD. The report describes the design and implementation of the XML DTD used for World Wide Web Consortium (W3C) specifications and notes related to XML.

We have released NextflowWorkbench 1.3. This new release makes it easier to create frozen docker images with the bioinformatics resources needed by your analysis pipeline. Creating frozen images is useful in two situations:
- You are organizing training sessions to show others how to use a workflow and you need a simple way for trainees to install all the required software. Creating a frozen docker image that includes all the dependencies, from software to data indices will help you save time. Trainees download the image and are ready to go without lengthy configurations.
- You need to create a frozen analysis pipeline for a clinical data analysis pipeline (i.e., in the context of CLIA and/or New York State clinical test regulations). You can package the workflow and its dependencies in a docker image that can be tagged and represents a frozen state of the software and data.
Creating such a frozen image got easier with release 1.3 of the NextflowWorkbench. You can use a special instruction (install gobyweb artifacts) inside the Dockerfile and declaratively indicate which resources are needed, as shown in this snapshot:
If you have defined this resource declaration in a Process or Bash script, you can simply type “install gobyweb artifacts” in the dockerfile and paste the resource bit of the statement (copy it from the script).
This special instruction will expand into a series of shell instructions that will install the requested software inside the image. The Process or script, when run, will automatically detect that the resources are present in the image and will run much faster, as these resources will not be installed again.
The following improvements are also included in release 1.3:
- Improved auto-completion for artifact paths and paths inside the docker image (for instance, auto-completion will now warn you if the interactive container is not running).
- Provide the ability to specify a current directory for interactive containers, so that relative path auto-completion knows what suggestions to offer when auto-completion is invoked.
- Add Salmon 0.5.0 to the list of resources that can be installed as a GobyWeb resource.

Instructor: 0:00 Sometimes it might be required to return a completely new set from a producer. For example, in the case where we add a reset button to our application to revert to the original set. Let's add a button and an event handler.
0:18 Remember, we will get initial set function already so our first bet will be to reuse it. The question is, how can we connect this initial state function to our drafts? The first guess might be to assign the initial set directly to our drafts, but that doesn't work.
0:34 You have to realize that this only reassigns the arguments to the function, but it doesn't change the drafts. This is quite similar to how you could not implement increments in the following way. This doesn't work.
0:47 This doesn't increase. Why? Why? Because it just reassigns the local parameters but not the original arguments.
0:55 Anyway, what is the proper way of achieving this? Well, this is actually quite simple. Immer allows you to return a completely fresh state from a recipe. Instead of updating our draft in this producer, we just return some new data and Immer will use that as the next state to be returned.

*If you’re new to my music project: I’m Michael, a music creator (I compose, play, record, create music), and I started uploading here on YouTube back in 2011.
I believe music can be much more than just pure entertainment. It can be a beautiful soundtrack that accompanies us through a moment, through the day or through life. My goal and journey is to create the most beautiful music possible - one track at a time.
Many use my recordings and piano music as background music while doing mental or creative work, as music for studying, to achieve better focus, doing homework, as relaxing music, spa, bar, lounge, cafe music, as music for yoga, while meditating or simply to fill their space with light, calm, peaceful and positive music.
This project is not as much about a genre as it is about a feeling. A way of life. With my tunes, I try to take a little heat and speed from our generally quite busy lives. A soundtrack for you, when you feel the need for calm and positive, cooling and liberating tunes.

IN THIS CHAPTER
Machine learning packages
Packages for maps and images
Text analysis packages
The projects I walk you through in this book are vehicles for sharpening your R skill set. These projects depend on R packages specialized for the topics I cover. In this chapter, I tell you about some packages that can serve as the foundation for additional projects, and for further honing your R skills.
These packages address subject areas I cover in this book, and one area that I don’t.
The goal of the
caret package is to make it easy for you to work with machine learning. Consistent with R formula notation, its simple syntax connects with a huge array of machine learning methods. Additionally, the package offers a number of data sets to try them out on. If I were writing a book about the gamut of machine learning, I'd include this package. (In fact, it might cover only this package.)
As its name implies, the
neuralnet package is all about neural networks. It goes beyond

Ok, the documentation says that the dot operator is used to extract components
- But the reason that I wrote it that way, is because I like to think of the
"C1.x" form as a short form of the dot product between the C1 vector and the
basis vector x.
It wasn't my intention to confuse anyone.
(Several ASCII-coded texts/papers/posts about vector math use the "." as the
vector dot product operator.)

First post here, thanks for the wealth of information thus far.
Okay, so I have a pair of Atomic "Daddy" carbon ski poles. They are extraordinarily light, and lasted me the better part of a season skiing with them before I wiped out and snapped one of them in two.
Recently, I stopped by Fiberlay in Seattle to pick up some carbon fiber and resin to patch the thing up, fixed it, made the mistake of skiing with them and broke it again. Now I have a mess of carbon on my pole and I am thinking of replacing the whole lower.
I am quite attached to the poles because of the fiscal consequences of replacing them. Before I dive into another round or laying up carbon...
Does anyone have any other bright ideas?

Laravel 5 select with sum query exampleBy Hardik Savani | June 8, 2016 | | 46150 Viewer | Category : Laravel
We mostly required to get sum of amount, salary etc in laravel. We can also get sum of column using mysql SUM(). We have two way to get sum of column value. first we can use laravel sum() of query builder and another one we can use with directly with select statement using DB::raw(). I give you both example you can see and use any one as perfect for you.
$data = DB::table("click")->sum('numberofclick');
$data = DB::table("click")
->select(DB::raw("SUM(numberofclick) as count"))

"helping clients to tell their story well"
So that's what we aimed to capture in our little poster (I benefitted from a bit of art direction from an outstanding designer friend +David Soutar).
In the process of finding the right balance of type and images I went through several iterations. Graphic design is as time consuming as coding, nowadays I tend to outsource design work to those more fluent, so that I can focus on coding (I really don't get those coders and managers who think that graphic design is a quick thing).
* note to self: rubbing up a flyer translated into about 4 hours of work plus USD$30 to purchaes the stock images used (in case I ever forget why we've started to outsource this stuff).

|
Last Update: 2016-04-20 18:41:05 UTC
This document explains the best practices when implementing and configuring environments for CA ARCserve RHA specifically with regards to various popular anti-virus applications available to date of this document.
Due to the sheer nature of replication read / write IO that is required the CA ARCserve RHA engine process should be excluded whenever possible from anti-virus 'On Read Access' or scanning all-together. This will alleviate additional IO overhead on the read access of the files that we need to capture changes from and also the amount of IO that occurs when we create our journal files for replication within the RHA “Spool” directory.
Many popular anti-virus solutions allow for an entire process to be excluded from scanning or at the very least “On read access” scans. These are below with information pertaining to how to enable such exclusions.
At a bare minimum the spool folder needs to be excluded from anti-virus 'On-Access Scanning'. The default location for the spool folder is '%SYSTEMDRIVE%\Program Files\CA\ARCserve RHA\engine\tmp'.
Whenever possible please also add in file exclusions for '*.jrnl'. These are the spool journal file extensions and will help reduce IO overhead if the spool folder is changed in the scenario from the default or user defined location that is already excluded.
In addition to this many anti-virus solutions allow for an entire process to be excluded. If possible please also add the 'ws_rep.exe' process as excluded from all 'On-Access' AV scanning. Below are some popular AV solutions with information on how to exclude a process from scanning.
Symantec Endpoint Protection:
Below are screen shots of how to exclude a process within Symantec Endpoint Protection
1. First open Symantec Endpoint Protection by right clicking on the right hand corner task menu
2. Then click on the options button for Virus and Spyware Protection
3. Then click on Change settings
4. On the Global Settings tab click on View List
5. Next click Add then click on Application Exception
6. Then browse to the ws_rep.exe process within the engine install directory. Select it and click OK
7. It will now show in the exceptions list
McAfee VirusScan Enterprise
Sophos does not allow for process exclusion, only folder and file within the GUI. But it does have the capability of exclusion a process with registry keys that also require reboots.
Create a string value called:
The value can then be for example: 'notepad.exe' to exclude the notepad.exe process.
If you need to exclude multiple processes you would need to create additional string keys, i.e.
with no gaps in the numbering, etc..
Kapersky Anti-Virus Enterprise Edition
Has a “trusted zone list” that allows for process exclusion as well:

Exp: to let the opened file go to this or that page ... perform some actions.
How do you do this?
What I do is set a global in the first file, then get this value in the opened file to use it as a trigger.
Is there any other way for doing this?

The idea of a forum is interesting. We sure have our Github for suggestions and issues, but most people don't use it or know how to use it. And it's also always good to hear what people want, whether from emails, polls or posts; albeit most of the time people won't know they want something until you show it to them. And that's mostly our place to think about new ways to make Notes better and improve it. Not degrading at all from the power of our users to tell us what they want, but it's imprtant to not be take every suggestion (even with majority) to be a final decision. We should everything under own ideas and values and choose the ones that fit the most with our vision.
I think Wix has some built-in forum capabilities, I should check out on that sometime.

Underflow occurs when the result of an arithmetic operation is smaller than the smallest normal floating point number of the target datatype. Smaller numbers, subnormal or denormal numbers, can be represented but with fewer bits of precision. Production of a subnormal numbers is called gradual underflow. One way to deal with such underflow is to flush denormal results to zero. This will lead to some loss of precision when results are very small but may improve performance since frequent gradual underflow calculations consume a lot of system time. If subnormal values are critical to the behavior of your program you should add the
-no-ftz option when using
-O1 or higher optimization level.
Flush denormal results to zero. This is the default option with every optimization except
Do not flush denormal results to zero
The Boost library version 1.61.0 includes bjam/b2 and the necessary files for building python extensions with Boost.Python. Boost.Python is a C++-library which enables interoperability between C++ and the Python programming language. Methods and abstracted data types implemented with C++ can be made availabe for use by Python.The Boost Web page lists what is supported by the library.
Example: Import methods to Python
Chapter 1 of Numerical Recipes implements three methods
- flmoon() :: The method calculates the phases of the moon
- julday() :: The method calculates the Julian Day Number
- caldat() :: The method returnd the date based on the Julian Day Number as input
With this methods available in a python interactive session it is for example easier to search for future occurrences of a full moon on Friday 13th ( a suggested exercise at the end of Chapter 1 of Numerical Recipes.)
Note that this page do not show the implementation of these methods. You need to go to Numerical Recipes to see the implementation
Let us first look at the methods interfaces
Both flmoon() and caldat() having arguments passing by reference. The results of the calculations are returned through these. This is not doable in Python. One way to get around this is by defining local variables and let the functions return a tuple. Note that the implementations in Numerical Recipes use defined types (Int and Doub). This example will use built-in types (int and double).
After the function decfini
Our directory have the following contents:
We now execute b2 or bjam (they are equivalent) in the directory containing flmoon.cpp. b2/bjam will build a debug version of the flmoon extension, which we can load into a python interpreter. We need to set the necessary environmental variables to have access to the Intel compiler, boost library and python - note the module loads before executing b2/bjam.
We start a python interpreter and load the extension library.

Last n rows
To flag the last n rows in a range, you can use helper column with a formula based on the ROW and ROWS functions. In the example shown, the formula in cell E5, copied down, is:
where data (B5:E15) and n (G5) are named ranges.
This formula returns TRUE if a row is a "last n row", and FALSE if not.
The core of this formula is based on another formula that calculates the "current row" in a range:
In brief, we get the current row in the workbook, then subtract the first row number of the range plus 1. The result is an adjusted row number that begins at 1. The INDEX function is simply one way get the first cell in a given range:
This is for convenience only. The formula could be re-written like as:
Once we have a current row number, we can compare the row number to the total rows in the data less n:
current_row > ROWS(data)-n
If this expression returns TRUE, the current row is one of the last n rows we are looking for.
Last n rows in a table
If data is in an Excel table, the formula can be adapted like this:
The logic is exactly the same, but we use a slightly different approach to get the first cell in the table:
You can think of the @ character as indicating "single":
As before, the table formula returns TRUE in "last n rows" and FALSE in others.
Last row only
To test for the last row only, you can use a slightly simplified version of the formula:

When Paul introduces new concepts, such as changing an image shape using .clipShape(), displaying an alert using .alert(), modifying the font color with .foregroundColor(.white) etc., I find myself wondering how he arrived at these design decisions. I can understand the code and replicate it by looking back, but when I look at the underlying Swift developer docs I can't make any sense of the thinking process and how he chooses the modifiers that he does.
To anyone reading, do you have any advice? Should I just chill and move forward and eventually I'll understand the process? Or should I spend some time reading through the dev docs to understand all of this in more depth?
Thank you for your time!
Background: I'm a beginner studying Swift and C#. Right now I'm working through this tutorial while reading the Swift Book
Hello! If you're asking about how I come to design decisions, it's almost entirely based on what I think looks good – there's no magic there. Apple does have a great many recommendations for creating iOS apps, called its Human Interface Guidelines. However for anything else, such as how I clip shapes or choose colors, it's mostly based on what I think looks good, backed up by whether it's relevant for the project.

This workshop will highlight the extensive research into seasonal and subseasonal climate prediction using data from the North American Multi-Model Ensemble (NMME) and Subseasonal Experiment (SubX). Participant abstracts should focus on the forecast problem, and include evaluation of prediction data from Phase I or Phase II of NMME, or SubX. Abstracts can use retrospective and/or realtime forecasts. The goal of the workshop is to move forward on the subseasonal and seasonal climate prediction through interaction between research teams.
- Model representation of physical processes, including but not limited to: modes of climate variability such as the El Nino Southern Oscillation (ENSO) or North Atlantic Oscillation (NAO) and their teleconnections; trends; climate mean and variability.
- Subseasonal/seasonal prediction skill of regional or global climate, including extremes.
- Multi-model forecast consolidation, including weighting, bias correction, or calibration.
The meeting will consist of keynote presentations and dedicated poster sessions. The poster sessions will be advertised with 2-slide "flash" talks.

|
code

When paging through data that comes from a DB, you need to know how many pages there will be to render the page jump controls.
Currently I do that by running the query twice, once wrapped in a
count() to determine the total results, and a second time with a limit applied to get back just the results I need for the current page.
This seems inefficient. Is there a better way to determine how many results would have been returned before
LIMIT was applied?
I am using PHP and Postgres.
SELECT foo , count(*) OVER() AS full_count FROM bar WHERE <some condition> ORDER BY <some col> LIMIT <pagesize> OFFSET <offset>;
Note that this can be considerably more expensive than without the total count. All rows have to be counted, and a possible shortcut taking just the top rows from a matching index may not be helpful any more.
Doesn't matter much with small tables or
LIMIT. Matters for a substantially bigger
Corner case: when
OFFSET is at least as great as the number of rows from the base query, no row is returned. So you also get no
full_count. Possible alternative:
Sequence of events in a
( 0. CTEs are evaluated and materialized separately. In Postgres 12 or later the planner may inline those like subqueries before going to work.) Not here.
JOINconditions, though none in your example) filter qualifying rows from the base table(s). The rest is based on the filtered subset.
GROUP BY and aggregate functions would go here.) Not here.
( 3. Other
SELECT list expressions are evaluated, based on grouped / aggregated columns.) Not here.
Window functions are applied depending on the
OVERclause and the frame specification of the function. The simple
count(*) OVER()is based on all qualifying rows.
DISTINCT ON would go here.) Not here.
OFFSETare applied based on the established order to select rows to return.
OFFSET becomes increasingly inefficient with a growing number of rows in the table. Consider alternative approaches if you need better performance:
Alternatives to get final count
There are completely different approaches to get the count of affected rows (not the full count before
LIMIT were applied). Postgres has internal bookkeeping how many rows where affected by the last SQL command. Some clients can access that information or count rows themselves (like psql).
For instance, you can retrieve the number of affected rows in plpgsql immediately after executing an SQL command with:
GET DIAGNOSTICS integer_var = ROW_COUNT;
Or you can use
pg_num_rows in PHP. Or similar functions in other clients.
As I describe on my blog, MySQL has a feature called SQL_CALC_FOUND_ROWS. This removes the need to do the query twice, but it still needs to do the query in its entireity, even if the limit clause would have allowed it to stop early.
As far as I know, there is no similar feature for PostgreSQL. One thing to watch out for when doing pagination (the most common thing for which LIMIT is used IMHO): doing an "OFFSET 1000 LIMIT 10" means that the DB has to fetch at least 1010 rows, even if it only gives you 10. A more performant way to do is to remember the value of the row you are ordering by for the previous row (the 1000th in this case) and rewrite the query like this: "... WHERE order_row > value_of_1000_th LIMIT 10". The advantage is that "order_row" is most probably indexed (if not, you've go a problem). The disadvantage being that if new elements are added between page views, this can get a little out of synch (but then again, it may not be observable by visitors and can be a big performance gain).
You could mitigate the performance penalty by not running the COUNT() query every time. Cache the number of pages for, say 5 minutes before the query is run again. Unless you're seeing a huge number of INSERTs, that should work just fine.
Since Postgres already does a certain amount of caching things, this type of method isn't as inefficient as it seems. It's definitely not doubling execution time. We have timers built into our DB layer, so I have seen the evidence.
Seeing as you need to know for the purpose of paging, I'd suggest running the full query once, writing the data to disk as a server-side cache, then feeding that through your paging mechanism.
If you're running the COUNT query for the purpose of deciding whether to provide the data to the user or not (i.e. if there are > X records, give back an error), you need to stick with the COUNT approach.

The previous parts of this series of blog entries showed how to log in to the FSI Server and uploading images with a client application using the OpenAPI. This episode will show how to handle directories, something that is in fact essential before even starting to upload images.
The top-level directories are created by adding an import profile of the desired name. This is not an image management task but an administrative task and can therefore not be performed via the OpenAPI. Please refer to the FSI Server manual to learn how to create an import profile.
In this URI the import profile would be called “path” and “to” and “dir” would be subdirectories in the import profile. Directories are created using PUT requests. Presuming the login process was implemented similar to the one described in part II, the Java code is quite simple:
WebResource directoryResource = client.resource(serviceURL + "directory/path/to/dir"); ActionResponse response = directoryResource.put(ActionResponse.class);
The response will contain a status code and in case of failure also an error description. Deleting a directory is more or less the same but is implemented using a DELETE request instead of a PUT request. Developers implementing client applications using this interface should keep in mind, that this will recursively delete the given directory including all files in subdirectories without requiring any further confirmation. Asking the user if he really wants to delete this directory needs to be implemented in the client application.
Moving or renaming directories is also quite simple to implement on the client side. Renaming directories is quite a complicated operation on the serverside though. This is due to the fact that a rename operation recursively renames all subdirectories including their files inside FSI Servers internal storage. A rename request for a directory containing a lot of files and subdirectories will therefore take accordingly long. Client application developers should make sure that these requests do not time out too quickly.
The rename or move request is a POST request to the source directory URI with a form parameters called “to” which contains the target directory as the value. The following example shows the Java code which moves /path/to/source/dir to /path/to/target/dir:
WebResource sourceDirectoryResource = client.resource(serviceURL + "service/directory/path/to/source/dir"); Form form = new Form();
form.add("to", "path/to/target/dir"); ActionResponse reponse = sourceDirectoryResource.post(ActionResponse.class, form);
Finally the directory URIs support GET requests. These will deliver an XML or JSON formatted list showing the directory contents, enabling developers to write applications to browse through the directory tree on the server.
The next part of this blog series will show how to rename, move and delete images on the server and conclude the series with some final thoughts.

|
code
|
Outlook 2003’s Quick Flags feature is a handy tool — if you can develop a logical system for using it. One solution: A custom toolbar that makes it easy to flag and organize messages.
Quick Flags help you categorize your messages, usually by some level of importance or by task. For instance, you might use a red flag to mark messages that need a quick response and a blue flag to mark messages on which you’ve acted and are waiting for a response.The problem with Quick Flags is that there’s no way to customize their descriptions. Outlook identifies them only by color. You can’t change the name of Red Flag to Critical. Remembering what each color represents can become burdensome.
An easy way to remember what each flag represents is to create a custom toolbar that displays each flag with text that means something to you. Fortunately, the process is easy:
- From the Tools menu, choose Customize.
- On the Toolbars tab, click New (Figure A).
- Name the new toolbar appropriately — for instance, you might name it Flags, as shown in Figure B — and click OK.
- Still in the Customize dialog box, click the Commands tab.
- Select Actions from the Categories list box (Figure C).
- Scroll down through the Commands list box to find the flag entries. Then, drag the appropriate flag color buttons onto your custom toolbar. (If you can’t find the toolbar, look behind the dialog box.)
- After adding all the flags you want, change the text for each flag button. Right-click a flag button on the toolbar and replace the Name setting, e.g., &Red Flag (Figure D), with something more helpful, such as Critical. Select the Image And Text option so that Outlook will display the button’s name on the toolbar (Figure E).
- Complete steps 6 and 7 for each flag button in your new toolbar.
Figure F shows an example of the finished toolbar.

Could I gain knowledge of the civet through our shared biological processes?
Maybe with the help of a coffee cherry.
Through the medium of art, literature, storytelling and ethnography, we collectively explore the shared heritage held between humans and animals within global commodity chains. Specifically, we investigate kopi luwak, the world’s most expensive coffee, traditionally produced from the excrement of civets.
With the rise of capitalism, civets’ relationships to humans have been transformed from one of fleeting local encounters to being an exploited other, as commodifiable goods and cultural symbols. Increasingly confined for industrialized kopi luwak production and tourism, civets find themselves ensnared within a politically and economically driven world of human-civet domination.
As an interdisciplinary collaboration between anthrozoologists and visual artists, we seek to problematize the commodification of wild animals and their “products”. Our collaborative work traverse the concept of “becoming with” another species by instrumentalizing our own human bodies. By uilizing that in which we physically share with civets we attempt to create a new form of storytelling where the animals' perspectives are observed through our shared biological processes.
On the one hand, explicitly addressing these concerns brings possibilities of positive social change for multi-species coexistence. On the other, our chosen method of multispecies storytelling brings about the need for further ethical consideration.

Hadoop Across Availability Zones
Hadoop is a great solution to the big data problem and with the instant access to servers and storage in the cloud, it’s easier than ever to spin up and manage your own cluster. If you haven’t heard too much about it yet, hadoop provides access to a distributed file system along with a framework for running map reduce jobs over the data. It takes care of replicating chunks of data to each node and running jobs in parallel for you. However, when you want to expand your hadoop cluster across availability zones you can run into some unexpected problems. So lets dig into the ideas we tried and the final solution that worked the best for our configuration.
Communicating across data centers is a pretty old problem with a lot of different solutions so we wanted to start out with the simplest thing we could think of. First, we decided to allow access by adding an elastic ip to each node and adding those addresses in the security group of the opposite availability zone. So this would basically just allow open communication from certain public addresses on the internet, which isn’t a bad solution. But if you ever need to replace or spin up a new node, it requires a decent bit of manual intervention to reassign the elastic ip or to create a new one and add it back to the security groups. Another downside is that, due to hadoop’s fancy hostname resolution, we can only utilize tasktrackers within the same availability zone as the namenode.
So next we tried using OpenVPN to create a bridge across the two networks, but there was one small problem. Because we didn’t have full control over what ip address our servers were assigned, there was the potential for two machines with the same ip on separate networks which would cause all kinds of weird problems. Amazon’s VPC can help solve this problem by giving you more control over the network but we decided to go a different route.
Instead of using a classic VPN solution, we gave tinc a try. Tinc is still considered a vpn daemon but instead of using it for a point to point connection, because it is so lightweight, you can install it on all of your servers and expose a new network interface to route traffic over. This allowed us to easily configure the vpn on the production system and then just switch the interface hadoop was listening on once everything was up and running. So here’s how we set it up.
Three files make up the basic configuration. The tinc-up script is responsible for creating the new network interface. The tinc.conf names the local node and keeps track of all the other nodes it needs to talk to. We also need a hosts file which is named after the local node we set in the tinc.conf. This file includes attributes for setting up the connection to the vpn like the external ip, vpn ip, vpn subnet and public key. Since we have everything already set up in chef we just set up a cookbook that ran a few searches across our servers and generated all the configuration files we needed. We also took advantage of hadoop’s rack awareness feature to make sure data is always streamed from the closest node and also makes sure replicas are spread across different data centers. There was only 1 problem that we came across which again involved hadoop’s hostname resolution. Map reduce jobs were periodically failing because the tasktracker would sometimes use the ec2 hostname and resolve the ip of a datanode incorrectly. So, we had to setup a tiny dns server to make sure that hostnames always pointed to correct tinc address. After fixing that everything worked great. We also had the added benefit of being able to connect through the vpn and access the files from hdfs directly using hue.
Since we quickly covered a lot of new technology, here are some useful resources for when you want to try this out yourself:
What other tips do you have on breaking the single availability zone barrier?

Do not be afraid to experiment with the most unexpected things
This title is basically the mantra of DIY projects. DIY is all about the following:
- Exploring your talent in creating or recreating things
- Finding out how much of a creative fantasy you have
- Finding out how you can reuse things, in order for them to still stay in the house and still make you happy.
- Working out in how many ways are you able to reuse the same thing, even after you are unable to use it for its original purposes.
- To explore how to make things more useful or useful again
- To work out how many things you can restore and reuse without having to trash them.
We need to add a few useful tips here:
- Know your limits: overdoing things is never good you do not want to look like a modern Ophelia
- Some things can be saved and revived the proper way. Give yourself time to see what’s the best method to use

The latest Kartotherian version runs fine under my own account on the prod server, but not as a firejailed service
I don't have access there, but this log line makes me think the problem might be in the configuration. Is the config using absolute or relative paths? If it's the latter, perhaps the wrong dir is used at the root?
Also, make sure service-runner's at the latest version (0.2.10)
Update: the service runs as a single instance, but fails as ncpu. This might be related to the fact that mapnik shared lib is used by a large number of npms
I had to refactor the code to avoid 10+ different singleton instances of mapnik, and now it starts ok.

Here you put the string you want to look for, normal searches would be a single word... but
you can use any number of words without problems (while the network plugin where to send the
search allow it), when you use more than one word is the destination network plugin (supernode)
the responsible of handling it on a "human readable" way... unfortunately this does not seems
to happen most of the times... to work against this behavior GiFTMui implements
some filters to get results e.g. on ordered words (as you typed it).
This object hasn't notification to the return key and therefore you'll need to click on the
Search Button to start the search.
The object is created using a String.mui subclass with history/cache facility, when a new search
request is sent the string you typed is stored on a private cache, you can access such cache
by using the RMB (right mouse button) over the string object and a context-menu with the
cached entrys will be shown. If you want the cache saved upon exit you'll have to active
the 'save on exit' switch available from the same context menu.
Attached to the string object there is a button as you can see (MUI's "tape down" image), this
is here to expand/replace the standard search panel to the advanced search panel mode, where you can finetune
the searches (explained below).
- - Realm
Here you can define what type of results you want to be returned, this could be
everything meaning any type of files, audio, video, images,
documents, or software. There are options as well to found files based
on its hash, or to browse a single user shares (if the protocol support it).
- - Max (Maximum number of results)
How many results do you want as maximum for your search requests, read the notes given to the
toolbar's stop button for additional info.
Note: The value set here is valid and used
as well while the advanced search panel is being used.
- - Paths
Activating this switch causes the paths to the files in the results to be shown, this is only
usefull if the network/supernode who give us the results uses pathed files.

App sucks wang Installed fine, took my provider log in and tried to watch a program but said "3g/4g has been disabled, can be changed in the app settings" that's bull, no matter what settings i changed in the app And on the device the show wouldn't play. Using a Samsung Galaxy express 3 and got rid of the app due to it being complete garbage.
Keeps getting better! In the last 8 months I have seen some much needed improvements with this app. It used to freeze during shows constantly to the point where I would give up. Now 95% of the time the videos work flawlessly. Super convenient to watch my favorite shows on my own time. Thanks for all your app improvements!
Grrrr 😧 I can watch one or two (MAYBE) episodes of my favorite shows. It'd be alright if they were not old and I didn't only like two shows in all of Travel Network. I work two jobs and still can't afford TV so this app is pointless. Why would I need the app if I could just record the shows on the TV in the first place?!?
Not worth it There are several episodes from weeks ago and there locked. You can't look at them unless you have cable. Whats the use of having this when I can just watch my cable tv if I have it. This app is not accessible for people without a cable provider.
Videos Don't Play I've tried reinstalling and installing this app to see if that will allow me to watch any video, but videos won't load. Even after signing in with my cable provider information, I'm unable to watch anything. They need to fix this ASAP.
WHY?! WHAT IS THE POINT?!? Seriously Travel Channel, what is the point of offering an app to let people watch and then ONLY allowing those with cable to use it? IF I HAD CABLE I WOULDN'T NEED THE APP!!! Everytime I try to watch Ghost Adventures or Deadly Possessions in full screen on my laptop the screen goes all wonky so I end up having to watch a minimized version. Found out about this app and was hoping this would work, but I don't have a cable provider. So no GAC on the go for me. :(

The action wizard lets you customize what happens when you, for example, press a widget or quick action button. They can be programmed to do many things.
"Device Actions" are used for triggering actions that run locally on your device. For example, Wake on LAN, opening the mouse, opening the keyboard, sending an IR signal, etc.
Note that many types of actions can also be programmed to trigger on a specific server (or active server to use the currently connected computer). This is useful if you want to control specific programs on specific computers.

Starting with release 18.104.22.168, over 4,000 icons are available for use in apps created with Touch UI. Icons can be applied to a page, view, or action to help the user in navigation and data manipulation.
By default, every application comes integrated with 1,650 icons from the Material icons library, provided for re-use by Google under the Apache License Version 2.0. There are 260 Halfling glyphicons (included with Bootstrap 3.0 under MIT License integrated as well. Additional icon libraries Font Awesome (730) and Ionicons (1,466) can be included using the method described in the last section of this article.
The picture below shows the page “Customers”. The page has been assigned the icon “material-icon-group”, and that icon is displayed as selected in the Quick Launch area of the sidebar. The Customers edit form has been assigned the same icon, displayed in the header of the view. The “New Orders” action has icon “material-icon-add-shopping-cart” applied, and the “New Customers” action has “material-icon-group-add” icon.
Learn how to assign icons to pages
. These icons will be displayed in related menus. Up to five page icons will be added to the Quick Launch area of the sidebar.
The “Apps” menu will display a grid of all page icons.
Icons can be assigned to views in order to better communicate the purpose of a particular form.
Adding relevant icons to actions
helps the user locate and understand the purpose of that action.
Only Material Icons and Halfling Glyphicons are included in Touch UI apps in order to reduce the size of the generated project and required download size for every client. Offline applications will have access to these icons. If more icons are needed, Font Awesome
library icons can be included. If additional icons are desired, please open a support ticket
for your request.
Let’s include icons from these two libraries. In the Project Designer
, press Open
to open the project folder in File Explorer
. Navigate to “~/WebSite/touch” folder. Right-click and press “New | Text Document”.
Name the file “custom-icons.css”. Double-click the file to open in your default text editor. Replace the contents with the following:
/*Font Awesome icons*/
Save the file and close the text editor.
Let’s use our new icons on some pages. Switch back to the Project Designer
. Make the following assignments:
On the toolbar, press Browse
. The new icons will be used on the sidebar and dropdown menus.
The icons will be visible in the site menu as well.

Subject: Re: Accessing driver from within kernel
To: Dave McConnell <firstname.lastname@example.org>
From: Martin Husemann <email@example.com>
Date: 05/07/1999 20:50:47
> More specifically, I want a network pseudo driver to be able to

Look at the way ISDN4BSD does it, it handles multiple (different) ISDN cards
and a few different pseudo devices accessing any of that cards.
It's two pointers to records of function pointers: one for functions
the ISDN card driver implements, one for functions the pseudo device
Example: when a packet arrives on a pseudo interface, this sends a dial
request message to userland. The userland daemon checks policies, selects
an ISDN card to use for the call and does an ioctl() to connect the pseudo
device and the hardware driver and allocate kernel state info for that
connection. It gets back a handle identifying that state info. All further
request from userland to kernel are done via that connection handle. Never
ever is a concrete ISDN card driver accessed by the userland daemon. So I end
up having three ISDN cards in one machine, but only needing one /dev/i4b.
There is userland access not to ISDN cards, but to B-channels, i.e. when
doing userland PPP (which I4B doesn't do right now). That is another pseudo
device driver, which gets connected to the hardware driver just like the
in-kernel PPP driver or the IP-over-HDLC driver.

I'm considering switching from that nasty Vista ( ) media center for my PVR in my living room. I'm going to test out LinuxMCE, but I have a couple of questions:
- What format does LinuxMCE store recorded TV shows to? Is it compressed? Is compression available?
- How much space does it take to store a one hour standard def TV show?
- What formats are supported for video? For instance, if I convert all our existing MS-DVR TV shows to XVid, will LinuxMCE "like" them?
Please respond if you can answer any or all of these.
* This depends on the tuner card selected, and if you are choosing to transcode the files after they've been recorded. Most of the time, if you're using a tuner card with MPEG-2 assisted hardware (i.e. the Hauppauge PVR-150/500/PVRUSB2), the files will be standard MPEG-2. Other devices now are MPEG-4 assisted (the Plextor devices), so the files will be in that format. Other generic cards will typically be Nuppelvideo container files containing either MJPEG or MPEG-4 streams.
* With mpeg-2? It takes me about 2.5 gigs.
* Pretty much anything Xine will play is supported. But I would stick with MPEG, AVI, MKV, DVD images, MP4, etc. You will have no problem with files encoded with the DivX or XVID codec.

In response to the COVID-19 pandemic, the White House and a coalition of leading research groups ( AI2, CZI, MSR, Georgetown, NIH) have prepared the COVID-19 Open Research Dataset (CORD-19). CORD-19 is a resource of over 29,000 scholarly articles, including over 13,000 with full text, about COVID-19, SARS-CoV-2, and related coronaviruses. This freely available dataset is provided to the global research community to apply recent advances in natural language processing and other AI techniques to generate new insights in support of the ongoing fight against this infectious disease. There is a growing urgency for these approaches because of the rapid acceleration in new coronavirus literature, making it difficult for the medical research community to keep up.
Maybe we need to generate data from the public themselves, perhaps each individual should make diary entries for each day irrespective of whether they have the virus or not, perhaps a standard form for diary entries should be proposed which can readily produced a consistent dataset. Possible entries could be.
- GPS Location
- Number Persons Close
- Number of Contacts per Day
- What Symptoms
- Washed Hands After What Activity
- Self Isolating
- Exercising in Isolation
Perhaps some of the above, and I am sure others could be suggested.
Not sure if this makes any sense but it’s just my 3 penny worth.
Might be useful …

Delta Chat, a new approach to decentralized messaging, uses Python in several ways. Delta Chat is a Whatsapp/Telegram-style messenger app which uses the existing e-mail server network instead of central servers. There is no address book upload, and no necessity to tie accounts to mobile numbers. We'll live- demo how "Chat over E-mail" works, with random audience members, in real-time.
We'll then look into how Python is used for automated testing (with pytest) against the messenger core library which is exposed through CFFI. However, the core library will soon be ported to full Rust. Are there better ways to interface Rust with Python than going through C-interfaces?
In the third part we'll introduce first example Chat Bots, written in Python. Do you want to send an machine-generated system allert to a sysadmin group? Or safely archive all media that is posted to a family group? Or have your IoT sensor react to commands or send info? Just do it without registering a bot to some central cite, or by exposing all content information to (e. g. Telegram) servers. A Chat Bot only needs access to a standard IMAP/SMTP account. We'll look at the simple Python API for writing and testing powerful and versatile Chat bots.

0 of these use a community maintained action and 0 of these have a release pipeline.
Sorry, but this doesn’t give a good image of the GH Actions product.
It’s good that you are from GH, maybe you can push some internal change.
In my opinion creating a release and pushing assets to it are basic features that have to be maintained by people from GitHub since it has a close relationship with GitHub API. I don’t want to trust my GitHub Token to a third party!
Other problem is there’s no GitHub Actions community right now, everything available is too immature. We need better reference documentation for it! Video teaching materials, a better way to search for stuff in each other’s CI workflows.
Sorry for being very critical, but GitHub sets a really high bar for everything, which is good, you guys do good work. But GitHub Actions really need more work before it can shine. After using Jenkins, GitLab, Travis, Circle CI, AppVeyor, TS, Azure, and CirrusCi I expected to settle for Actions and was a bit disappointed that it had to be another one for me to juggle.

Okaay… So… How are you?
… On my side, I’ve been having quite some fun studying QM. I’ve reached a certain point in my studies, and it seems like this is a right time to take a little break, and write down an update, and thereby keep some momentum going at this blog.
Today I am going to write a little bit about three neat resources on QM, and also share some random thoughts, which occurred to me as a result of my wondering as to why I find these resources useful. In the process, I am going to touch a bit on the various approaches for systematically presenting a difficult topic like QM. The approaches I have in mind are: deduction-oriented, historically sequenced, and some combination of the two. Finally, I will also write a bit about a new ambition that has arisen in my mind. … OK, so let’s get going…
Lecture notes (and even full text-books) on QM tend to be organized in a highly deductive manner, especially when it comes to the topic of the QM spin. OTOH, many of you probably are very well aware that I tend to dislike any deduction-heavy treatments, even if these come from Nobel laureates and are highly praised, e.g., The Feynman Lectures vol. 2 and 3. … If fully or almost fully deductive, then sometimes, I even hate them—I mean such notes and books, the prime example here being: Dirac’s book on QM! … So… Where do we begin?
Ummm… First, a word about how the element of deduction can be put to some good use too!…
1. Some textbooks / lecture-notes / course-videos lean towards a deductive approach but still are good:
One good point with a somewhat deductively organized presentation is that it can achieve a greater efficiency in teaching—assuming that a class-room teacher (not to mention TAs for conducting the recitation sessions) are available to the student for clarifying his doubts and difficulties right then and there in an informal, personal, settings. A somewhat deduction-oriented pedagogy has its uses, given the time constraints of the typical university schedules—provided that it’s done right—and provided that resources like systematic recitation (or tutorial) sessions are available.
However, in general, if the organization of topics is more heavily slanted towards deduction, then, even if TAs are available, the main teacher himself has to be very careful. He has to exercise special care, especially on these two counts:
- he has to keep on giving at least some “intuitive” feel for the logical starting point of each topic separately, again and again, and
- the scope of the logical “fanning out” to implications, starting from the major premise(s) selected for deduction, also has to be kept judiciously delimited.
Deduction is powerful—too powerful, in fact! Just like a sharp, double-edged sword. If handled right, it can work wonders. In teaching-learning, it means: Deduction is useful to the student provided he already knows the general outline and meaning of a topic and its scope. But if you are completely new to a topic, then a deduction-heavy treatment is more likely to induce in you a large number of small but enduring misconceptions. Reason: Objectively speaking, induction has primacy. Deny it its rightful role by suppressing it, and it’s going to try and figure out some way out of the suppression. Splintering of knowledge, therefore, is a very easy possibility—if not splintering of the mind as well!
However, if due care is exercised on the aforementioned two counts, then a semi-deductive treatment can come in quite handy. Let me give you an example from engineering, just to illustrate what I have in mind here.
Consider the very first course in engineering mechanics, viz., the vector mechanics of Newtonian particles and rigid bodies.
For more than two centuries, physicists actually theorized certain natural phenomena, and solved problems related to these, without ever using the idea of vectors. They explicitly worked with systems of equations: three coupled scalar equations, one each formulated along a principal coordinate axis.
So, a pedagogical approach that sticks to a purely historical order would have to teach all the topics in applied mechanics—not just acceleration in , and angular momentum, and the Coriolis forces, and everything else, but eventually, also the entirety of Maxwell-Lorentz EM—using only systems of coupled scalar equations! The task of teaching would become unwieldy in practice (and require black-boards on all sides of a class-room, with student-chairs that can rotate through degrees). The task of learning would become even harder, and therefore, knowledge would become accessible to relatively very few students.
However, experience shows that a combination of the historical and the deductive approaches does work great for engineering mechanics. It definitely takes less amount of time to generate a good grasp of the subject for most students. (To get to the best possible grasp, you have no choice but to look up the history and fill in the details from such sources, purely on your own.)
So, what you do, for courses in engineering mechanics, using the “combination” approach, is this:
You begin with the separate scalar component equations, and list them once. But you actually use them only in the simplest cases like motion of particles in and (e.g. the parabolic path of a projectile, the uniform circular motion, etc.). Then, soon enough, you take a jump of approximately one–two centuries, and immediately introduce the idea of vectors right at this stage. You don’t get into all the complications of the concept, like the distinction between a true vector and a pseudo-vector, right at this stage. And, you certainly don’t give a formal definition of vector spaces at all. But, you do begin deploying the idea of vectors in calculations. And, you do so using only a simplified (or “curtailed”) sense of the term “vector” (which is: as a directed line segment). Then, as the physical systems to be analyzed become more and more complex, you also go on expanding and clarifying the idea of vectors and operations with them further. You introduce the scalar and cross products of vectors, and explain the necessity of their differences in reference to different aspects of physical phenomena, then you go on to the calculus of vector-valued functions, etc…
So, all in all, you are going back and forth in history a bit, but without necessarily creating too much confusion about the proper hierarchical relations among the physical concepts. Going back and forth in this way is OK, up to an extent, if the jumping around is kept limited to the concepts and techniques of mathematics. However, I would definitely say, such jumping around does not work for the concepts and contents of physics as such.
Now, an interesting fact here is that a lot of ideas from physics also have a heavy methodological, even mathematical, context to them. For example, ideas like: the variational principles (taught initially as the “energy” principles), operators, and of course, the spin in QM.
Teaching such topics too can become more efficient using the “combination” approach, but then, doing so requires a teacher who is comparatively more skillful, and also, much more careful.
The combination approach might be characterized, using a slightly more fundmental terminology, as the following:
Start with the phenomenological knowledge, and use induction to introduce certain important facts that are also generally applicable. Then, translate these preliminary ideas into more formal concepts. These new, formal concepts might themselves be of a far greater methodological scope, but start using them anyway, without pondering over all aspects of the expansion in scope which such a formalization implicitly brings in. Then start working out simple mathematical manipulations, while using the greatly generalized formalism, but only in the simpler contexts, and thereby make students comfortable with the rules of manipulations as well as the hieroglyphics (i.e. symbols). Then progressively go on fleshing up the meaning behind the symbolism as the student understanding deepens (and his facility in using the rules and symbols improves). And, all through this activity, always keep on dropping small bits of physical insights (or at least some hints) which show where the “floor” of the “ocean” lies. Do that frequently.
It works. Provided that, what the teacher is aiming at is only a more systematic treatment, i.e., if, emphatically, he has not sold out his soul to deduction as such. Not all teachers or textbook writers are of the latter kind.
Now, the trouble with today’s teachers (and text-book writers) is that they just don’t know how to stop short of being an outright slave to deduction—and in the process, they also pull their students in the same vortex. Their short-coming is especially evident as the physics gets more and more complicated and therefore more and more abstract, starting right from the fields idea in EM, and up to the modern physics of special relativity and QM.
[Aside: IMO, not even that great teacher—Feynman—could manage this challenge right, always. In evidence, see his deductive treatment in the Volume 2 of his Lectures, and compare it not just with Resnick and Halliday, or Sears and Zemansky, but also with Purcell (recently updated by Morin). I don’t know about you, but I would always go in for the latter three as my primary sources for learning. Once you have already learnt the topics, then Feynman does become good—especially for the occasional insights that are hard to find elsewhere (and more occasionally, for your cocktail party points). Personally, I have avoided The Feynman Lectures’ second volume (after a rapid but careful browsing some three decades ago). Aside over.]
So, yes, using some degree of a deductively oriented organization can lead to efficiency in terms of classroom time. Actually, the gain is in terms of generating an averagely good sort of competency, in the least possible time, for more number of students. But such methodology also is a bit more demanding on the main teacher.
And, this problem becomes an order of magnitude worse when it comes to teaching quantum mechanics.
That’s why, when one runs into a mildly-deductive treatment of QM that’s also done competently, one not only appreciates it, one also wants to applaud it. In this post, I will mention two such examples.
2. “Notes on Quantum Mechanics” by Prof. Daniel Schroeder:
This is a set of notes for an introductory UG course on QM at the Weber State University, available here [^].
The organization and presentation style followed in these notes is such that a definite slant towards deduction is very easy to make out. Yet, the writing is such that the notes remain very easy to follow—even in the absence of a class-room teacher, i.e., even for a “pure” self-study mode (without any video recordings and all).
I had noticed these notes some couple of years ago or so, but in the sea of all the material available on the ‘net for QM, I had come to postpone reading through it, back then. Then, some time later, I somehow came to forget about these notes.
Recently, I checked out Prof. Schroeder’s Web pages after a while; found a new version of these notes; and immediately downloaded the freely available PDF [ (PDF) ^]. A quick browsing later, I now decided to keep the MIT course-work on a further hold, and instead to go through these notes first.
Turns out that it was a very good decision to make.
By now, I have gone through the angular momentum- and spin-related parts of this book. (I skipped most of the initial parts of the book, simply because I knew those topics pretty well.) I have found the treatment of the QM spin here to be outstanding.
It in fact is the best introduction to spin among all notes and books I have seen so far.
Yes, the treatment of the spin here is, IMO, better than that in Townsend’s text-book. Reason: Schroeder’s notes are short, more readable, and the problems too are “doable”. In contrast, Townsend’s book is big in size, too big in fact. (I think it’s 800 pages long. I have merely browsed through it once or twice, but have not properly read through even one section completely. (TBD later!))
The treatment of spin in Schroeder’s notes also is better than that in Eisberg and Resnick (and many other text-books). An important reason: Schroeder’s notes have a distinctly modern “flavour”, and so, you can so easily transition from the introductory QM to reading the special-purpose books and literature (say on the QC) without much effort.
Another plus point:
These notes are the only source I know of which shows how to “implement” two-state systems using the spatial wavefunctions (i.e. without at all using the spin).
[Aside: To tell you the truth, I had independently figured out something like this—two-state systems using only some time ago, as also the fact that entanglement can be explained in reference to the spin-less particles too.
… The earliest memory I have about thinking of entanglement with only spatial wavefunctions, i.e., without involving any spin at all, goes back at least to November 2014, when I was teaching engineering courses in Mumbai; and then, a highlight also occurred around Diwali-time in 2017. … But my ideas were rather “conceptual” in nature. Actually, my ideas were relatively vague, though they were not quite “floating” abstractions. And remember, all my studies and research in QM has been purely on a part-time basis, except for the last one year (since the Covid-19 began).
Anyway, when I saw Schroeder’s paper, “Entanglement isn’t just for spin” [^] (which was may be in 2018 or so), I remember, how I had marveled at it. Now, coming back to the present, to these notes, the marvel repeated. I mean, it was pleasant to read a description which was also physics-wise fully correct! Aside over.]
The only “downside” (if it can be called that) which I found with Schroeder’s notes is this:
There is no coverage of topics like the “total” wavefunction (spatial + spinor) for the many-particle systems. … May be it was not practical for them to cover this topic during their regular university coursework. However, an additional chapter dealing with the details of this topic would have been very helpful.
Added attraction: The simulation applets written by the author himself. (His HTML5 code is clean!)
All in all:
Strongly recommended, especially for the topic of the spin.
If you come from a BS in CS sort of a background, but have never studied QM beyond the Modern Physics courses, and still, if you have somehow grown very enthusiastic about the QC, and are championing it around, then, for God’s sake, let me dispense away this completely gratuitous and unsought advice to you:
Don’t even consider opening your mouth to champion the QC until you have have already mastered this book, cover-to-cover, complete with solving the section-end problems too. (As to for my opinion about the pre-requisites required for this book, see the section 4. below.)
And yes, I mean it!
3. “Quirky Quantum Concepts: The Anti-Textbook” by Prof. Eric Michelsen:
I’ve forgotten the track of where I gathered about Prof. Michelsen’s background (even if I did it within the last fortnight!). Anyway, here it is, in brief. Michelsen started out as an engineer. He spent quite some time (“decades”) in engineering industry (IIRC, in electronics / semiconductors). Then, I gather, he also founded start-ups in software. Then, he turned to research, and did a PhD in lasers and astrophysics, from UCSD. He is now a professor at UCSD [^].
… In short, I might say that I am sort of like him (or he is sort of like me), minus his practical success. [See the endnote at the end of this section.]
…Anyway, to come back to the “Anti-Textbook” by Prof. Michelsen….
Looks like I had downloaded an old PDF for the draft of this book too, though I don’t seem to have much of a recollection of my initial impressions about it. May be I had downloaded it around the same time as Schroeder’s notes were (i.e. in 2018 or so). I guess I must have downloaded this book, looked at some equations, and closed the PDF, saying to myself that I would have to return to it for a careful look later on. Then, as usual, I must have come to forget it along with Schroeder’s notes too.
Anyway, so… A couple of weeks ago or so, I once again downloaded the latest copy of Michelsen’s draft. (The book has been published by Springer, but the draft version is still available for free, here [ (PDF) ^] ).
I am still going through it. However, by now, I have read significant parts from: chapter 2 (“Riding the Wave: More on Wave Mechanics”), chapter 4 (“Matrix Mechanics”), and some initial parts from chapter 5 (“Angular Momentum”). In particular, I’ve not yet completed the portion on the spin, and haven’t even begun with the next chapter (which is on the many-particle systems).
I am plain astounded at the richness of the insights offered here, full stop. This is one of the best resources for understanding the subtle aspects of QM.
Again, sometimes, I was even stunned to find the same insights as I myself had come to develop, independently. … Not so mysterious! The very approach of engineers is like that. Engineers (I mean: people who have worked as engineers for long enough of time so as to internalize the peculiar approach of engineering) do tend to think in a subtly (but definitely) different way than “pure” physicists do. (And we won’t even mention mathematicians here!) That’s why, it shouldn’t come as a surprise that when two engineers think deeply about the same new subject, there is a considerably similarity in terms of all: how they approach it, what they find interesting in it, and what they choose to highlight or take up for detailed considerations.
Of course, with his further formal training in physics (at the level of a PhD in physics), Michelsen has a much better knowledge of the mainstream QM than I do. He certainly has far more insights to offer on the more advanced aspects of the mainstream QM. These are difficult topics, and my studies of QM itself are relatively much more limited. I am not even aware of some of the topics whose quirkiness he notes. Yet, since his thinking retains the characteristic fold of an engineer’s thought processes, I have not found major difficulty in getting his points—even if these are quite quirky!
So, all in all, I think I can say this about my impression of this book (at this point of time):
I can always understand what Michelsen is saying, and often times, I also find myself having already worked through to precisely the same (or very similar) conclusions. However, I don’t always anticipate all his insights pertaining to the peculiarities of the mainstream QM.
But, yes, one way or the other, I find that his book is packed with insights. Even if you are not an engineer, you should benefit tremendously from this book. … Don’t take my word for it. Just go through the book and see for yourself. … OK. Let me copy-paste just one insight (just to help concretize this point); the following excerpt is from the draft copy page 49 (i.e. p. 51 of the PDF file):
Observable Operators Do Not Produce States Resulting From Measurements:
The mathematical result of an observable operator acting on a state is very different from the state resulting from actually measuring that observable.
Many people confuse the result of an observable operator on a state with the act of measuring that observable. These are very different things!
Note that the act of measurement is a nonlinear operation on the wave function; it can not be represented by a linear operator acting on the wave function. Recall that the whole point of a linear operator is to produce a superposition of results based on the superposition that composes the given function (or ket). In contrast, the consequence of a measurement is to choose one specific state out of a superposition of eigenstates.
A measurement eliminates a superposition, in favor of a more definite state. Therefore, a measurement is not a linear operation on the state; it is inherently nonlinear.
[Emphasis in bold original.]
See, see, why I am so impressed with this book? (And if you can’t figure out the reason, then check out my Outline document, here [(PDF) ^].)
… The entire book is filled with such nuggets.
No, this book is not at all induction-primary; it’s not even a historically sequenced presentation. In fact, this book isn’t even your usual text-book. Read the Preface to see why the author himself calls it an “Anti-Textbook”. …So, yes, this book is quirky! But yes, it’s quite rich in insights too.
So far, all that I’ve done is to rapidly read through the aforementioned chapters. But I don’t think that I’ve had enough opportunity to ponder over every subtle point, every nuance. I will have to read through the remaining parts, and then, I will have to return and re-read some parts again (may be 2–3 times).
The whole book is a kind of a teaser, as it were, to me. (Yes, my hard-copy is full of underlines, margin notes, scribblings, and all.)
Yes, this book is going to keep me engaged for quite some time to come.
However, no, do not bring up some points from this book for discussion with me. Not right away. I still have to learn a lot, and I am definitely quite a distance away from mastering the pre-requisite contents. I am also not likely to attempt mastering it any time soon. Reason: Many of these topics are not relevant to the research on Foundations of QM as such, even though the book deals with many advanced or subtle aspects of the mainstream QM, in a very admirable way.
As to me: First, I have to complete the first version of my document on my new approach to QM. Before that, I’ve to complete the MIT course 08.05 (i.e., watching videos). Before that, I’ve to complete the second half of MIT 08.04 too.
So, the bottomline is this:
Bottomline: One of the best books for really learning the subtleties of QM that I’ve ever come across, at such a level that it should be accessible even to the undergraduate students.
But make sure that you have completed the pre-requisites.
[Endnote to section 4: Why do I say that I am like Dr. Michelsen, minus his practical success? … Well, some of you should know the background behind that statement already, but in case you’ve just begun visiting this blog in the more recent times, there is a story about me and UCSD (which doesn’t come up on my CV)…:
After my failure in the PhD qualifiers at UAB in 1993, I was admitted to the mechanics program at UCSD, for the academic year beginning Fall ’93. … Not bad for a guy with a “mere” 8.25/10.00 CGPA at IITM and a 3.16/04.00 GPA at UAB. … OTOH, in fact, people at UCSD were (very) impressed by me. Reason? A literature review document which I had (on my own) attached to my application. It was on the micro-mechanics of fracture in ceramic composites. … Ummm, yes, the document was pretty good. So, they had decided to have me on board as soon as the funding arrives (which was around the May–June 1993 times).
However, roughly around the same time, even their on-going funding got cut down. So, formally, they said that they will keep the offer open for me for at least a year (which, eventually, they did), and informally, they called me to discuss the situation in all its detail with me. (By they, I mean the professors, not the staff at the graduate school.) Some of their on-going PhD students, supported previously via the funded projects which were now cancelled, began working in Pizza Hut, I gathered. I was willing to follow the suit. But starting completely afresh just on Pizz-Hut, i.e., without any prior savings, was not at all practical, someone (an IITian) doing his PhD there told me. The professors confirmed this assessment too, during the several telephonic discussions I had with them. … Anyway, all in all, I had to let go their offer, and return to India (which was in the last week of August ’93).
… BTW, my admission letter at UCSD was signed by Prof. Nemat-Nasser, the then Chair of the program. He and his colleagues had already brought this mechanics PhD program to a very good reputation; it was already ranked within the top 10 US-based programs or so. For comparison: My earlier program at UAB was ranked 60+ at that time (within about 70 PhD programs, in all, in the USA). … BTW, eventually, Prof. Nemat-Nasser also went on to receive the Timoshenko Medal. As to this medal …Well, yes, you may think of it as the “Nobel” of applied mechanics [^] [^]. … So, that’s the part related to UCSD…
… But coming back to the other aspects of practical success: As to my later experience in software, in particular, in the SF Bay Area… Well, ask me some other time, preferably in private (so I can be a bit free-er in my… err… expressions). Footnote over. ]
4. Revised recommended sequence for learning QM through self-studies alone:
If you want to study QM through the self-study mode (i.e. completely on your own, without any personal guidance from any one), then condensing down everything (including whatever I have said about this topic in the past, and now revising it), here is my advice in a nut-shell:
Follow this sequence:
Resnick and Halliday / Sears and Zemansky + if necessary, Purcell (updated by Morin) Beiser (Modern Physics) First half of McQuarry (Quantum Chemistry), up to and including the Helium atom + augmented readings for the same topics from Atkins (Molecular Chem.) Schroeder’s notes Eisberg and Resnick, Alastair I. M. Rae, and may be an occasional look into others like Griffiths / Gasiorowicz Michelsen.
For the last two stages, you can start with Michelsen and “dip back” into Griffiths etc. as the need arises. Also, consider watching the video series by ViaScience (mentioned in my earlier post here [^]) any time after you are past the books on quantum chemistry (including the He atom).
[Aside: Once my viewing of the MIT course-work (08.04 and 08.05) is over, it’s possible that I will revise the above sequence. So far, I’m half-way through 08.04 (2013 version), and I’m impressed with it. However, I don’t think that I am going to include the MIT course work in the shortest sequence presented above, and I don’t think I am eventually going to drop anything from the above sequence either. So, there. Aside over.]
Addendum: If your interest is in the Foundations of QM, rather than in QM itself or the QC, then my advice would depend on your background.
If you come with a background in physical / engineering sciences, then go through the above mentioned sequence at least up to and including Schroeder’s notes. Then, follow this sequence:
Travis Norsen (Foundations of QM) Tim Maudlin (Philosophy of Physics: Quantum Theory), both augmented with David Harriman (Induction in Physics).
(BTW, I have only browsed through some initial parts of Maudlin’s book, but I can definitely recommend it without any reservations.)
If you come with a background in other sciences or philosophy, then follow this sequence:
David Harriman (Induction in Physics) + Tim Maudlin (Philosophy of Physics: Quantum Theory), in any order Travis Norsen (Foundations of QM).
If you cannot understand the physics part of Harriman’s or Maudlin’s book even after a second or a third reading, then I would suggest: Quit pursuing Foundations of QM; this field is not for you. The field of Foundations of QM has a far greater basis in physics rather than philosophy—regardless of what other people might have led you to believe.
But if you still must persist with this field (Foundations of QM) at any cost, then quit pursuing all philosophical and popular science books on this topic (including those by Bell, and Bohmians), and instead, begin with the first sequence (given above), right from Resnick & Halliday etc., and going up to (and including) Schroeder’s notes. Once you are through with it (which should take at least a couple of years, may be 3–4 years), then once again check out Maudlin. If you can follow it right on the first read, then you may follow either of the two sequences given for the Foundations of QM.
5. A new, personal, long-term ambition:
Now that I had accidentally “re-discovered” the two gems mentioned above (the notes by Schroeder and Michelsen), I chastened myself a bit. Then, straining my memory, I remembered about
Malcom Longair’s book: “Quantum Concepts in Physics: An Alternative Approach to the Understanding of Quantum Mechanics”.
I had bought this book way back [^]. However, I have never been able to take it up for a systematic and comprehensive reading. … All that I’ve been able to do is sometimes to “take a dip” into it, may be for some 2–3 pages at a time, only then to toss it aside once again. “No right time for this book!” That’s what I’ve been saying to myself, invariably…
The last time I checked Longair’s book was, may be, 3+ years ago. It certainly was at least months before February 2019, which is when I wrote the Outline document [^].
A few days ago, I picked up this book once again. It was the first time I was touching it after the Outline document was posted. Presently, I came to a conclusion.
But before telling you the conclusion, let me ask: Remember Dr. Jennifer Coopersmith’s book “The Lazy Universe”? I had mentioned it pretty recently, just a few posts ago, here [^]. In the preface to her book, Coopersmith says that her book is like a simplified version of Lanczos’ book on the variational calculus. Now, Lanczos’ book is the Ultimate One, when it comes to the calculus of variations (i.e. the “energy” principles). And Coopersmith seems to have handled the simplification very well…
Now, coming back to Longair’s book and my long-term ambition.
I would like to write a simplified account of QM, based on Longair’s book.
The write up would be in a text-book like manner—complete with some solved problems and some review questions.
I would like to work at it slowly, one section at a time, and also irregularly, as my free time permits. I would like to post each section (or sub-section) in a GitHub repo or so. It will be, by intention, a long-term, and also irregular, hobby project.
But why rewrite a book if the original itself is so great?
Well, there are multiple reasons for that:
Yes, Longair has done a very admirable, scholarly, job in his book. However, he also gives greater detail of the initial analyses of experimental results, events and personalities than what a modern UG student of QM could possibly handle. If the goal is to simplify the presentation, one could omit many such details—precisely because Longair’s book is there!
Another point. Just the way the teacher has to exercise great care when presenting anything with a deduction-oriented approach (e.g. vector mechanics), similarly, the teacher also has to exercise a great care when presenting anything with a historically-oriented approach. Reason: Following the historical sequence helps in achieving a focus on the inductive roots of concepts and ideas. However, the former does not automatically ensure the latter. Isolation of the inductive roots is a separate task by itself.
With my enhanced understanding of induction (as brought about by David Harriman’s book “Induction in Physics”), I think that I can have a good shot at simplification. …
Let me be clear: I wouldn’t be explaining, let alone proving, how this or that development does have inductive roots; that’s not my goal. But I would like to present the physics points in such a way that their inductive roots become easier to grasp (even if they don’t become inescapable). I might not always do a great job for this aim; it’s too lofty for me. But I do think that I stand a good chance in converting the description from a mainly historically oriented account to one that is (i) simplified and (ii) highlights the nature of the respective inductive generalizations performed by the physicists at various stages of the main development. I think I can do that, to an acceptable degree.
One more point: I also think that, in the process of developing my new approach to QM, I’ve achieved a good clarity regarding what the mainstream QM theory is trying to say. This greater clarity, brought about by my new approach, should help in my goal, even if the explicit concern remains only with the development of the mainstream theory.
OK, so… I will begin working on it some time after the upcoming document on my new approach is done. I will work at it purely at leisure, purely as a hobby, and by intention, without any explicit plan… I think one should have some long-term hobby project like that going at any time…
6. But when will I start writing my planned document on the new approach?
Oh well. You tell me. … I’ve already told you the status as of now, and also the plan. Here it is—the plan—once again:
A few days more for going through Schroeder and Michelsen II half of MIT 08.04 (videos) MIT 08.05 Some rest Thinking as to how my new approach holds up—if it does! And, if it does hold—and I see no reason why it shouldn’t hold, including for the spin–then (and only then) Some planning for writing Start actually writing.
So, whaddaya think? When will I begin writing (that goddman document on that goddamn new approach of mine)? …
Well… Want to consult astrologers / tarot card readers / psychics? … Fine by me! Just let me know what they think (if they do), and then, also, what you think, if you do, after you have heard from them. … Or may be, want to consult some AI program? may be after you implementing a rough-and-ready one? Fine by me, again! … Or, perhaps, want to put to a practical use some certifiably random RNG (random number generator)? simply on the grounds that QM is supposed to be fundamentally random, and physics is universal? Or simpler still: want to toss a coin a few times? … Once again, fine by me. Whatever floats your boat! … From my sides, I’m all ears…
As to me, from my side, I will come back with a status update some time after watching the videos for the MIT 08.04 course is over, and watching for 08.05 is already in progress… That is, may be after two weeks or so (unless I have some brief update to post or so)…
In the meanwhile, take care, and bye for now…
Two songs I like:
Actually, I’ve two songs this time around. … Let me first give the credits and the links for both:
(Hindi) हम प्यार में जलने वालों को… (“ham pyaar mein jalane waalon ko…”)
Singer: Lata Mangeshkar
Lyrics: Rajinder Krishan
Music: Madan Mohan
A good audio for the original version is here [^]. There are other versions, including a so-called “revival” series version, but I won’t bother to give you the links to them.
The second song I have in mind is this:
(Hindi) फिर तेरी कहानी याद आयी… (“phir teri kahaani yaad aayee…”)
Singer: Lata Mangeshkar
Lyrics: Shaqeel Badayuni
A good quality audio is here [^].
Both are Hindi film songs based on Indian classical music. Both are sung by Lata. Both have been composed by highly acclaimed music composers. The two songs also have a certain unmistakable kind of a similarity in terms of certain turns of the tune, certain phrases of melody, so to speak. Both are serious kind of songs, evoking a sombre kind of a mood, one that borders on sadness but in a somewhat abstract sense. Further, people usually describe both these songs in quite superlative terms, and generally speaking, I quite agree with such assessments too.
However, personally, I happen to like one of them a bit more than the other. The question is: Which one? And, why, i.e., for what aspects / reasons? (And we consider only the audio aspects of the two songs here.) …
… I will let you think for a bit about it, and only then tell you my answer, in briefest possible terms, say in one sentence or two at the most, say via an update to this post (which may occur after 2–3 days or so). … In the meanwhile, happy guessing and / or consulting (once again) astrologers / tarot card readers / psychics / whoever, or even using (or implementing) an AI, or using RNGs / tossing coins. … Optionally, thinking too!…
BTW, if the songs are new to you, see if you enjoy any of them, or both…
Bye for now and take care…

Is it possible to run the tiling window manager i3 in just one of FVWMs virtual desktops?
That is: Say I have three virtual desktops “A”, “B” and “C”. I want to run i3 inside the virtual desktop called “A” only. Virtual desktops “B” and “C” should just be normal FVWM VTs.
Is that possible?
Why I ask this question: I think tiling window managers are bad at most tasks. I therefore prefere to use plain FVWM for most tasks, but tiling window managers are very good when it comes to terminal intensive tasks or programming. I would therefore like to start i3 in just one FVWM VT and be able to switch back and forth between i3 and normal FVWM without having to Lock out and in all the time.
Kind regards and thank

How can I add the following functionality to a checkbox: Show Text when checked, hide text when deckecked?
Just create an "On Toggle" + "Hide" event for the checkbox, with the Text as the target to be hidden.
Create a 'hide' event in the onclick option of the checkbox with a condition. Take a look at the attached image:
Is it possible to do the same thing with a button? I.e. if I click on a text such as "login" to make the login boxes "appear" and "hide" each time I press that button?
I can get it to appear but not sure how to hide.
Yes it is possible. But in this case you will need at least one variable in order to control when the button is pressed. Check out the following example where the login button shows and hides a group of inputs:
Thanks, that helped me as well.
When I try to do this i dont understand how to get that else action please specify
First you have to define the first condition (when login_pressed = 'false') -> shows Group_1. Then, just below that it will appear a link saying else. Click it and you will be able to define the else case. Take a look at this video http://www.justinmind.com/prototyper/... as well.

Text-to-speech is one area that is growing rapidly in the world of technology. This article will review Speechify, an application for text-to speech that is popular due to its user-friendly interface and innovative features. So, let’s dive in and find out what makes Speechify stand out from the competition!
What is Speechify?
Speechify is an innovative text-to speech application that converts text from a variety of sources into natural sounding speech. Speechify’s primary goal is to improve productivity and make information more accessible for people who have difficulty reading or prefer to listen to content.
App is available for iOS, Android and Mac OS, Windows, as well as Chrome Extension. Users can access the app on their preferred device.
How Speechify Works
Using Speechify is simple and straightforward. Users can import webpages or documents directly into the application. Speechify converts text into speech that can be played on your device or downloaded as an audio file to play offline.
Speechify’s text-to-speech engine is powered by advanced artificial intelligence, resulting in natural and high-quality speech output. This technology makes the content easy to understand for the listener.
The app supports multiple languages and accents, making it a versatile tool for users who need to access content in various languages.
The user can select from a variety of voices, adjust the volume and pitch to create an experience that is tailored to his or her preferences.
With Speechify, users have the option to adjust the playback speed to suit their listening pace. This feature is particularly useful for those who need to consume information more quickly, or at a slower speed to better understand the content.
Speechify allows users to easily import documents from a variety of sources such as Google Drive Dropbox, email attachments and webpages. This ensures that users can access and listen to content from different platforms without any hassle.
Who Is Speechify For?
Speechify is designed for a wide range of users, including:

for the new microstation BT:
How many BT connected devices will be remembered (so that I don't have to Pair every time I switch devices)?
Are there noises (beeps/tones) emitted over the outputs when devices connect or disconnect? If yes, can these be muted or turned way down? - My current BT receiver makes connect/disconnect noises and when the device is turned up to full volume these sounds are extremely loud. To avoid this, I have to remember to turn down the master volume before connecting/disconnecting - but sometimes the connection/disconnection is automatic such as when turning on a TV with Bluetooth transmitter built-in.

Tales from writing a RPN evaluator in Perl 5, Perl 6 and Haskell
I've been toying with the idea of learning a bit of Haskell or Perl 6, and now you've made me want to learn both. And I still have so much plain old Perl 5 to learn!
I'm only a part-time programmer! Have mercy, please...
I make decisions, and my brain carries them out
My brain makes the decisions, and I observe them (if I'm lucky)
I make some decisions, and my brain makes others
My spouse makes decisions and I and my brain carry them out
I wrote a program to relieve me and my brain from the burden of decision-making
The black-helicopter people project the decisions into my brain and then I do as ordered

Welcome back to another week of learning to code. This week we will dig a little more into some JQuery methods and begin working directly with an API. Until now, we have used the Yahoo Query Language too simplify the task of interacting with the Google API. Today we will begin interacting with the Alpha Vantage API, which offers real-time and historical stock quote information. This API has a very low barrier to entry, which makes it ideal for a learning environment. Today we will build a simple app that will allow a user to query the API for information on a particular stock. So, let’s get started.
Now, let’s start looking at our searchStock() function. We begin by referencing the table named output and the div tag named message. As before, we want to clear out the innerHTML in case of the user resubmitting the form. We also want to reference the stockSymbol that the user has typed in to the search box. Now, we begin looking at some more JQuery functionality. Remember, the dollar sign is the same as typing ‘JQuery’. So, $.getJSON could also be typed as JQuery.getJSON.
The getJSON() method is a shorthand way of calling the same Ajax method that we used last week. In this example, our first argument is the URL, which is a concatenation of our function call to the API, the symbol from our user, and our API key. The second argument is the success function that will be called on the data returned from the URL. We then create an empty array that will hold our HTML that we will eventually append to the output table. Our first element of this array will be the header for our table, which will include the stock symbol that our user has typed in. Here, we are again using template literals. Now, we want to show all the stock info to our user as rows in the table. So, we use the .each() JQuery method to iterate over the data and create cells for each key value pair in our JSON. Lastly, we want to present the user with an error message if no data is returned (i.e. the user typed in a bad stock symbol) and append our header and rows to the output table.
Throughout this short tutorial you have learned a little more JQuery functionality and how it can be used to simplify an HTTP request. Next week will add some more functionality to this little app to make it more responsive. Stay tuned. If you have any questions, please use the comment section below. Remember to share this post on your favorite social media platform. Thanks for stopping by, and I will see you all again next week.

At the PMS level, a system is described as an interconnected set of components, or individual devices, associated with a set of operations that work on a medium of information measured in bits (or some other base). Such a description is complicated by the amount of detail involved. It takes a whole manual, for instance, to describe the operations of a major computer, such as the IBM System/370. Thus the descriptive system must permit very compressed descriptions. It must also permit description of only those aspects of the components that are of interest, ignoring the rest. And what is of interest at the PMS level? Besides a description of the gross structure of a computer system, it is primarily the analysis of the amounts of information held in various components, the flows of information between components, and the distribution of the control that accomplishes these flows.
Thus a PMS-level description is analogous to the chemical engineer's diagram of a refinery in which the interest is in various kinds of liquid and gas flow. The engineer has to account for matter and energy loss with the system at various stages involving the transduction of materials from one form to another. A specific chemical plant's external performance is measured in terms of its production flow rate for a given cost. With computers, external performance is concerned with the economical accomplishment of discrete tasks, but at the PMS level this translates into operation rates and cost of operations.
For the PMS level we ignore all the fine structure of information processing and consider a system consisting of components that work on a homogeneous medium called information. Information comes in packets, called "i-units" (for information units), and is measured in bits (or equivalent units, such as characters). I-units have the sort of hierarchical structure indicated by the statement, A record consists of 300 words; a word consists of 4 bytes; a byte consists of 8 bits. A record, then, contains 300 ´ 4 ´ 8 = 9,600 bits. Each of these numbers-300, 4, 8-is called a length, since one often thinks of an i-unit as a spatial sequence of the next lower i-units of which it is composed. For example, one speaks of "word length," and of a record as "300 words long."
Other than being decomposable into a hierarchy of factors, i-units have no other structure at the PMS level. They do have a referent, i.e., a meaning. Thus it is possible to say of an i-unit that it refers to an employer's payroll, to the pressure of a boiler, or to a prime number satisfying certain conditions. To do so, of course, the i-units encode the information necessary to make the reference. At the PMS level we are not concerned with what is referred to, but only with the fact that certain components transform i-units but do not modify their meaning. In fact, these meaning-preserving operations are the most basic information- processing operations of all, and they provide the basic classification of computer components.
In PMS there are seven basic component types, each distinguished by the kinds of operations it performs:
Memory, M. A component that holds or stores information (i.e., i-units) over time. Its operations are reading i-units out of the memory and writing i-units into the memory. Each memory that holds more than a single i-unit has associated with it an addressing system by means of which particular i-units can be designated or selected. A memory can also be considered as a switch to a number of submemories. The i-units are not changed in any way by being stored in a memory.
Link, L. A component that transfers information (i.e., i-units) from one place to another in a computer system. It has fixed ports. The operation is that of transmitting an i-unit (or a sequence of them) from the component at one port to the component at the other. Again, except for the change in spatial position, there is no change of any sort in the i-units.
Control, K A component that evokes the operations of other components in the system. All other components are taken to consist of a set of discrete operations, each of which, when evoked, accomplishes some discrete transformation of state. With the exception of a processor, P, all other components are essentially passive and require some other active agent (a K) to set them into small episodes of activity.
Switch, S. A component that constructs a link between other components. Each switch has associated with it a set of possible links, and its operations consist of setting some of these links and breaking others.
Transducer, T. A component that changes the i-unit used to encode a given meaning (i.e., a given referent). The change may involve the medium used to encode the basic bits (e.g., voltage levels to magnetic flux, or voltage levels to holes in a paper card), or it may involve the structure of the i-unit (e.g., bit-serial to bit-parallel). Note that T's are meaning-preserving but not necessarily information-preserving (in number of bits), since the encodings of the (invariant) meaning need not be equally optimal.
Data-operation, D. A component that produces i-units with new meanings. It is this component that accomplishes all the data-operations, e.g., arithmetic, logic, and shifting.

I have created a way for real case numbers to automatically populate a text file (*.txt) on a daily basis. The main issue I have is how to force users to either enter or select the correct case number. There are roughly 250 case numbers and the format is the same for the case numbers.

The Gigabyte GA-C847N is a Mini-ITX motherboard with a soldered Celeron 847 CPU. It uses the Intel NM70 chipset and has one PCI slot. Let’s take a look at this little board.
The Celeron 847 is derived from the mobile version of the second generation Core i3 (Sandy Bridge) CPU, aimed at low-cost laptops. Its nominal clock is 1.1 GHz and it has 2 MiB of L3 memory cache. The main difference to a mobile Core i3 processor is the lack of the Hyper-Threading technology. It also has a smaller amount of L3 memory cache, since second-generation Core i3 mobile CPUs have an L3 memory cache of 3 MiB.
The NM70 chipset, despite its name (that looks like an Atom family chipset), is a low TDP version of the HM75 chipset.
You can see the Gigabyte C847N motherboard in Figure 1.

Also it had white text with black background but this was fixed by changing tooltip_*g_color settings in gtkrc file.
$ sudo apt-get install libwebkitgtk-1.0-0
sudo apt-get install libwebkitgtk-1.0-0
I had the same problem with Eclipse after upgraded my Ubuntu to 13.04.
After installed libwebkitgtk it works fine (I'm using Eclipse Kepler).
This works for Lubuntu 12.10 running Eclipse from the repository. Apparently libwebkitgtk-1.0-0 is not a dependency, at least not in Lubuntu.

[update: New DENG Build: 1.0.44]
I just published a new DENG build, that fixes some bugs and adds some minor features:
- fixed: Memory leaks. Some object cross references prevented the DENG component from unloading.
- fixed: Whitespace as first character in a block element with “white-space: normal” applied. Leading whitespace is now removed.
- fixed: _level0 references and callbacks in deng.swf made it difficult to load DENG into custom Flash projects.
- added: Support for <ul />. Unordered lists now display a bullet as marker.
- added: Support for <br />. The line break tag now defaults to “display: block”.
As we are slowly moving to a different hosting, the sources are currently not available from CVS.
DENG 1.0.43 sources: http://deng.com.br/deng_1_0_43_src.rar
I also published a demo showing how to use DENG with Flash projects compiled with Flash MX 2004, Flash 8 or MTASC, and how to use a standard vertical scrollbar (here: UIScrollBar v2 component) with DENG.
By the way, the DENG support forum moved:

Simply Easy Learning
About the Book
The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. This is the foundation for data communication for the World Wide Web (i.e. internet) since 1990. HTTP is a generic and stateless protocol which can be used for other purposes as well using extensions of its request methods, error codes, and headers.
This tutorial is based on RFC-2616 specification, which defines the protocol referred to as HTTP/1.1. HTTP/1.1 is a revision of the original HTTP (HTTP/1.0). A major difference between HTTP/1.0 and HTTP/1.1 is that HTTP/1.0 uses a new connection for each request/response exchange, whereas HTTP/1.1 connection may be used for one or more request/response exchanges.
This tutorial has been prepared for computer science graduates and web developers to help them understand the basic-to-advanced level concepts related to Hypertext Transfer Protocol (HTTP).
Before proceeding with this tutorial, it is good to have a basic understanding of web concepts, web browsers, web servers, client and server architecture based softwares.

Firefox (Windows, Linux, Mac): Snapper is a new Firefox extensions that can capture web pages as images. After installing Snapper, you’ll get a fish icon in your status bar. Clicking on this icon causes the fish to open it’s mouth! Now you are in capture mode. Click and drag around the portion that you want to save as image and a file save dialog pops up asking you the location to save the image.
Snapper makes it too simple. Watch this screencast.

Google Chrome Tricks
1. Jump to address bar:
Generally , Peoples uses the mouse cursor pointing on address bar and clicking on it. But we can also reach on address bar freom anywhere in browser using multiple ways like: Pressing Ctrl + L, F6, and Alt + D
2. Auto adding WWW. and .com in website URL
Just write the website name in address bar like gmail. then press the combination of CTRL+ENTER key. it will fill the www. before the gmail(website name) and .com in the last. for example, if you entered gmail in address bar and then pressed the CTRL + ENTER key then you will see the www.gmail.com in address bar and also no need to press the enter key again. It will be proceed to be open automatically.
3. Moving Browser TABs:
You can move the TABs using your keyboard instead of mouse and it is also faster then mouse. For example , in below image third TAB is opened but we want to move on first TAB.
To move First TAB we need to press CTRL + 1.
If we want to move on 8th TAB then we will enter CTRL + 9
4. Scroll Up and Down
This is easy , faster and amazing. generally peoples use the mouse to scroll up and down the website page. Sometime , peoples use the up and down arrow for scroll the page. But we can use the SHIFT key for scroll down and SHIFT + SPACE for scroll up. Best thing is , it is faster than both arrow key and mouse.
5. Instant image search
Suppose if you are searching images on on google. and want to open an image in separate TAB. This can also be done using keyboard but it will work in only chrome.
suppose , you are having below images output in google. Now you want to open third image in separate TAB.
Just press ‘S’ key and keep hold and than right click on the image.
Result will be like below:
6. Private browsing
Generally We use the incognito in chrome and private browser in Firefox. When we are working on shared computer. So cookies and history can’t be create. We can open incognito by just enter CTRL + SHIFT + N. If We want to open private mode browser in Firefox / explorer then we have to use CTRL + SHIFT + P.
Note: You can get the unexpected result in the case of Firefox. Like if you are pressing CTRL+SHIFT+P. then in result a print window can be open. But it will work fine with chrome.
7. Saving space in Bookmark Section
We can delete the name of site and can save the bookmark with icon only. It save the space in toolbar an we can see multiple sites in single row. In Chrome: right click the bookmark > edit > delete the name and save.
8. Mouse Wheel Button
This mouse wheel button (middle button) can be use to click on links and open the websites in new tab as well as we can close the tab by using this button. Just we nee to press this button instead of rotating.
9. Copy URL Faster
Generally, We copy the link URL by right clicking on link and then select ‘ copy link address’ But we can copy URL more faster way. Just right click on URL and then press the ‘E’ key.
10. Zoom In & Zoom Out
We can use CTRL + plus sign (+) to increase zoom and CTRL + minus sign (-) for decrease the zoom. To reset to the default zoom level we can use CTRL + 0.

TaskPaper 3.3 (216)
OS X 10.10.5
When I click on a task to mark it @done, TaskPaper scrolls to wherever the cursor happens to be. This is often outside the portion of the document visible in the window, and the view jumps away from what I was looking at when I clicked. This is annoying, as I then have to scroll back to where I was.
This is similar to the bug reported here,
except that the scrolling is to the cursor, not necessarily the top of the document.

Ciao a tutti!
Here we are with the second part of one of the most successful series of the blog!
This time there will be 4 videos, with both Italian and English subtitles so that also people that don't still speak Italian fluently can fully enjoy and learn Italian gestures.
Before we start, i want to express my gratitude again to Jin and Ken, they accepted gladly my unusual request to participate in this project, but in the end i can say that we had so much fun doing these videos.
We start with the most iconic italian gesture; it means "what are saying?!/"what are you talking about?!"" or "what are you doing!?", i think 99% of Italians do that gesture when talking.
Then there are gestures used when we want to say that someone is crazy and when we want to express that is cold or hot.
The second video, show another iconic gesture, used when we want to say: "eeh, you'd like to know!" when answering to a question, such us what did you do the other day?, where did you where going with that beautiful girl? etc..
The second gesture is used when we want to say that we have run out of something (gesture already used in the first part of his series), while the last one is used when we want to say that we have done something "more or less" or when we have almost finished to do something or finished something like money.
This video shows gestures used to express when someone want to invite another person to go to drink something. The second one is used when saying ok, while last one is used when saying to someone that he/she will see him/her later (the classic see you later! catch you up later!).
You can't miss our last video, full of gestures and really entertaining!
The first one is used when expressing that something was really boring (so boring that my beard grew very long waiting for its end).
The second one is used when hungry.
Third one used when inviting someone to go to eat some pasta, the gesture evoke the fork rolled to grab our iconic food.
Last one used when saying let's go, or when you want to say someone to go away because you don't want to be with him.
We are done for this lesson, hope you enjoyed this post as much as the first one.
Below you will find the same videos with Italian subtitles.

Postbox is a program that enables users to manage different and various mail accounts using one interface. Postbox catalogs and provides quick searching of each and every type of content that is found in emails such as attachments, documents, pictures, addresses, links, contacts, and text. Content and email messages can be located, viewed, and edited easily.
When an email is clicked on, a preview pane displays all links, attachments, images, and text that are contained in it. An Archive function moves messages which users do not want to tackle with immediately into the Archive folder. For content to be shared online, users select online services to be used. Web connections are made from the program Inspector Pane or Search Tab. Any type of IMAP or email account like Zimbra, Dreamhost, AOL, Hotmail, Yahoo!, iCloud/MobileMe, Comcast, and Rackspace, can be used with the program. Messages can be organized according to Topics, such as events, clients, priorities, or projects. Thumbnails of pictures found in email messages can all be viewed via the tab titled Images. Files and documents can all be browsed through the Attachments option. Email confidentiality and privacy information are preserved. The program protects the computer from Trojan horses, viruses, and spyware by comparing and reviewing URLS sent to users to a database for suspected malware and phishing sites. Warning messages are displayed when malicious URS are detected. “To-Do” messages and reminders can also be incorporated into one’s Inbox.

This is a tricky one. I don't like profanity around my kids, but the eldest (coming up 8) knows enough bad words, and can maturely act around the words. The middle child is just expanding on speech so picks these things up very quickly. I try to encourage the oldest one to see that swearing is just an extension of language, used mainly when stupid people have run out of the right words to say, when people are trying to elicit a reaction, or when people are trying to be funny. I am trying to teach her that it's ok, sometimes, to use profanities, in the right context.
This may sound extremely silly, but we also have a game where we try and insult each other, by putting together interesting words and not swearing.
When I was a kid, I lived in Germany, on an Army base. Aged 6 (I can quite clearly remember it), I was playing a game and when I lost, I was told the forfeit was to say something very rude (as I now know it to be), to a cantankerous old German woman who cleaned the officers houses. I did, and she fair beat the crap out of me. Taught me an interesting lesson...
I don't really swear; I am not really often in a situation in which swearing would add value to the situation, but I do understand that it is all about, and you shouldn't really keep it underground with a kid who is bright enough to get it.
I am also teaching her that in other languages, swearing and insulting people is an interesting part of the culture. In the 1960's, we lived in Hong Kong and I still marvel at how Cantonese people speak to each other. Russians have an equally interesting take on insults.
As an aside, my 8 year old is just starting to understand irony properly and, for me, it's a stepping stone to really getting into, really understanding languages. I think profanity is similar in this fact too.

We bought a PICO 5203. The advertisement of the PICO technology announced that the drivers of PICO 5203 cover the Visual Basic.
However, ps5000sdk_r6_0_12 does not include any Visual Basic sample programs and header files for the library functions. Does this mean that we cannot use the Visual Basic for the control of PICO5203 or that you are preparing them and supply them soon?
The table of "Full List of Drivers and Examples" in http://www.picotech.com/drivers.html
indicates that only PICO 520x does not have any VB sample programs. This table correctly reflects the situation of the driver soft ps5000sdk_r6_0_12. Then, does your press announce have a mistake? Why do you not supply the VB samples only for PICO520x? Do the library functions for PICO520x have some problems for the usage in th Visual Basic? PICO 320x has almost same types of API functions as PICO520x and you supply the VB sample programs for PICO 320x. What happend to the PICO 520x drivers? Just now we are going to make Visula Basic programs for the controll of PICO 520x by ourselves modifying the PICO 3204 VB programing examples. Is this attempt impossible and will be failed?

https://www.gamedev.net/topic/634566-picasim-flight-simulator-for-radio-controller-airplanes/
|
code
|
This is a simulator for radio controlled planes - mainly gliders (because that's what I fly and know) but also a couple of powered planes. It is as accurate and realistic as I've been able to make it, so the aerodynamics are pretty good, but also it has quite a realistic representation of the wind/air flow over hills (generating lift), thermals and turbulence.
At the moment it's available on Android, iOS and Windows - details here:
On Windows the controllability is much improved when plugging in a R/C transmitter or gamepad. Either on the mobile devices or on desktop, you can definitely use the sim to learn to fly, or practise aerobatics etc. It also has some timed races using Scoreloop for leaderboards (on the mobile versions).
In terms of technology I'm using:
1. Bullet for the rigid body physics.
2. Marmalade to help get it cross-platform. This has been a very mixed blessing - when it works it is great, and being able to develop for iOS without needing a Mac is brilliant. However, it has a lot of bugs/oddness that the "community" support has not been able to resolve.
3. The aerodynamics are all home-grown, mostly based on my earlier, open source simulator here. It divides up the aerodynamic components into sections, calculates the forces on each, and then sums the results. Everything thus just emerges - the nature of the stalls, spins etc. In addition you can scale the plane size etc in the sim.
4. The rendering is pretty basic. For 3D views the terrain uses continuous LOD with geomorphing (yes, a little old fashioned I know!), and the "panoramic" views use a skybox, with the terrain rendered only into the depth buffer.
5. The audio samples are mostly home-made - going out for the wind sounds, and blowing/whistling into a mic for the gliders! The audio processing converts the sounds to 3D and adds Doppler etc.
It's been an interesting experience getting something that is fully polished and usable, which people can just pick up and fly, or delve into the settings and modify practically everything. It's a lot harder getting the UI design right than the tech!
Marmalade is a very mixed bag. They sell it as a silver bullet for portability, but there are still many issues with it. I've worked at larger companies paying the price of a new car for yearly Marmalade licences and the full commercial support have the similar problems with Marmalade.
@PurpleAmethyst Yes - I really struggle with it - it is a great system that seems to be in a constant "beta" (alpha for some of the features) state, with bugs that just never seem to go away. I have very mixed feelings about it, but I guess when push comes to shove, I renew my licence!
I would say to any dev considering it, though, make sure you check that you can work with every module that you think you will need before licencing it, because there is, effectively, no official support (at least for the affordable licences) that will actually guarantee the bugs you find (and you will find bugs) will be fixed - or even that you will get any official guidance on working around them.
Things are better now - their community forum has been improved (though I find it quite clunky and disorganised) and they actually have a system for reporting bugs!
The positive spin on this, though, is that if you do want to make something cross platform, it's definitely worth considering.

I am using the bukkit plugin Swornguns which is suppose to add all of these different types of guns to your server which are also suppose to include realistic texture for the guns. I am using bukkit version 1.11 and I believe that I am using Swornguns version 1.11, but for some apparent reason, the texture is not working on the gun. For example, instead of looking realistic, its just a wooden hoe. Any reason why this might be? Thanks.

Active Directory: What it is and why it’s useful
Active Directory is a service created by Microsoft for the Windows operating system. It’s typically found in Windows Server domains and is used for the purposes of centralizing network administration and security protocols. User authentication and software updates, among other administration tasks, are handled by the service, allowing them to be spread across the whole network without the administrator having to manually update each computer or account on the system. An example would be that when a user logs into the network, Active Directory would then verify the password and check to see if that user is a system administrator or simply a regular user.
For a brief technical explanation, Active Directory structures are arrangements of “objects” and the information attached to them. Objects consist of resources like printers, computers, users, and workgroups and security principles, which are the user, computer, or workgroup accounts. Principles are assigned unique security identifiers or SIDs. Objects can contain other objects depending on the type, and each object has its own unique ID and set of attributes that consist of the information associated with the object and its characteristics. These attributes are defined by a “schema object” which also determines what type of objects are stored by Active Directory.
Schema objects are system controller objects that allow modification or deactivation of objects contained in the system the schema applies to, with changes made to them propagating automatically through the entire system controlled by the schema. This can be used by systems and network administrators to modify whole networks quickly. However, because of the far-reaching impacts of changing the schema, planning is often required to ensure system integrity and continuity throughout the network the schema controls.
The other major object type is called a “site object” which is physical, geographic location that hosts networks within the system, such as server units and domain controller units.
The structure of an Active Directory system itself is divided into three different categories or levels. The base level is called a “domain”, identified by its DNS name structure or “namespace”, and consists of the objects grouped inside it. The next level up is called a “tree”, which is a collection of one or more domains and linked domain trees in a collective namespace, all communicating with each other through security protocols known as “trusts” that come in a small variety of different types and configurations. The top level is called a “forest”, which is a collection of domain trees that share common global catalogs, logical structures, directory structures, and schema objects. The forest also determines the security boundaries of the assets and resources it contains, determining access within the various domain trees.
Further options exist for the grouping of objects, such as Organizational Units or OUs, which Microsoft suggests using as opposed to domains for ease of administration. Group Policy Objects or GPOs are typically implemented within OUs, helping to simplify overall administration within systems. Another is Shadow Groups; however these are not a default option and have to be built manually using a program like Visual Basic.
Worth noting is that there exists methods for using Active Directory with Unix or Linux systems through third-party programs, although certain functions may not work and limitations may apply since Active Directory would not be running native within a Unix-based system.
In conclusion, Active Directory provides a powerful and flexible tool for systems and network administrators to manage the large networks and server configurations needed by today’s business world. Any IT specialist focused in the fields of network administration and repair would do well and definitely increase their marketable skill set by learning the complexities and possible implementations of this service.

Air traffic control using FM Band broadcast emissions to implement air traffic control Radar is attractive to developing nations since it utilises existing, well supported infrastructure, such as FM Broadcast and Mobile Telephony, providing emissions and data connectivity respectively. In the current work we present a multistatic, multi frequency band, commensal, Radar system architecture and a suite of tools to design and implement such a system. The system we describe consists of spatially distributed transmitters and receivers, operating at different frequencies. The receivers do not process the direct signal, which is recorded independently, and shared by network. We outline the simulation tools we have developed to assist in the deployment of this technology in the most operationally effective way. These tools include multisite radar simulation and modelling of multistatic radar cross section and propagation using terrain elevation models.

The cellular neuroscience research lab led by Dr. Molly Stanley opened at the University of Vermont in August 2022
Researching Food-Brain Connections at a cellular level
What should I eat? When should I eat? How much should I eat? All animals must regularly make these important feeding decisions. These food choices then impact the overall health and well-being of the animal.
The nervous systemplays a critical role in each step of this process: detecting a variety of chemicals found in food & drink, sensing internal levels of energy & nutrients, forming associations and memories with specific foods, and ultimately integrating all of this information to coordinate appropriate food intake.
In the Biology Department at the University of Vermont, our lab will use the fruit fly as a model organism to study the molecules, genes, cells, and neural circuits that impact feeding behavior and health.

In the famous “Bridge of Death” scene in Monty Python and the Holy Grail, some of the knights are asked to name their favorite color. One of them mistakenly says blue instead of yellow and is hurled into the Gorge of Eternal Peril.
I can sympathize with the unfortunate chap. If asked my least favorite part of the tax code, I sometimes get confused because there are so many possible answers.
Do I most despise the high tax rates that undermine economic growth?
Am I more upset about the pervasive double taxation of income that is saved and invested?
How about the distorting loopholes for politically connected interest groups?
And the anxiety of taxpayers who can’t figure out how to comply with an ever-changing tax code?
Depending on my mood and time of day, any of these options might be at the top of my list.
But I also might say that I’m most upset about the way that the tax code facilitates a perverse form of legalized corruption in Washington. In this FBN interview, I explain how even small tax bills often are vehicles for lining the pockets of lobbyists and politicians.
To elaborate, some taxpayers may pay more when there’s new tax legislation and some may pay less. But this “winners” and “losers” game only applies outside the beltway.
The inside-the-beltway crowd always wins. Whether they’re lobbying for or against a provision, they get very big checks. Whether they’re voting yes or no on legislation, they’re getting showered with campaign contributions.
This chart, showing the growing number of pages in the tax code (by the way, we’re now up to 76,000 pages of tax law), also could be seen as a proxy for how the Washington establishment has gamed the system so that they always profit.
Or, to be more specific, it’s an example of how government has become a racket for the benefit of insiders. All of us pay more and endure less growth, but Washington’s gilded class lives fat and happy because there is always lots of money changing hands.
So how do we solve this problem?
The answer, at least for a period of time, in the flat tax. This video explains how this simple and fair system would operate.
But even though I’m a big advocate of tax reform, the flat tax is only a partial solution.
Simply stated, there’s no way to reduce Washington corruption until and unless you shrink the size and scope of the federal government.
That means somehow figuring out how to restore the Constitution’s limits on Washington. For much of our nation’s history, federal spending consumed only about 3 percent of our economic output.
And when the public sector was small and government generally focused only on core competencies, there wasn’t nearly as much opportunity for the graft and sleaze that characterize modern Washington.
P.S. The bad news is that all the projections show that the federal government will get far bigger in the future. So before we shrink the burden of government, we first need to come up with ways to keep it from growing.
P.P.S. The national sales tax is another intermediate option for reducing DC corruption, though that option requires repeal of the 16th Amendment so politicians don’t pull a bait-and-switch game and stick up with both an income tax and consumption tax.

Hack 21. Generate Folder and File Listings for Printing or Editing
Longtime PC users and former Mac users alike are often shocked when they realize there's no easy, built-in option to print a list of files in a folder. This hack creates a context-menu right-click option to create such a list, which you can then edit, copy, paste, andmost usefullyprint.
How many times have you been browsing through directories in Windows Explorer and wished you could generate a text file or printout listing the files and folders? It seems like such a simple request that it's amazing the option isn't available. You don't believe me? Right-click a folder and see for yourself if there is an option to list or print the structure. There isn't, but there is a workaround that doesn't require any third-party software. Here's how to create a context menu item [Hack #28] that, when clicked, generates a printable (and editable) text-file listing of the selected directory.
To create the entry in the context menu it's necessary to first create a batch file. A batch file is a text file that contains a sequence of commands for a computer operating system and uses the .bat extension. The format for the .bat file is:
dir /a /-p /o:gen >filelisting.txt
The name of the .txt file can be whatever you like. In this example, I've used filelisting.txt, but it could just as easily be filelist, listoffiles, namedfiles, or even Wally if you enjoy the bizarre in your file-naming schemes. Once you've decided on the filename, create the file in Notepad, as shown in Figure 3-1.
Figure 3-1. Creating a batch file in Notepad
Save the file in your WINDOWS folder, as shown in Figure 3-2, making sure to use the .bat extension and not the default .txt extension. It's important to set "Save as type" to All Files and "Encoding" to ANSI.
Figure 3-2. Saving filelisting.bat
Now that we have the .bat file created, the next step is to make it functional and easily accessible by integrating it into the context menu that opens when a right-click is executed. Open Windows Explorer and choose Tools Folder Options File Types tab Folder Advanced New to open the New Action box shown in Figure 3-3.
Figure 3-3. Creating a new action for the context menu
In the Action box, type the name that you want to appear in the context menu. Once again, you have wide latitude in choices; something like Create File Listing will probably be most useful, but you can name yours something more confusing if you like. Browse to the location of the .bat file you created, and select it in the box labeled "Application used to perform action." Click OK, and you'll see that Create File Listing (or whatever you chose as an action name) has been added as one of the Actions in the Edit File Type window, as shown in Figure 3-4. Do the standard Windows dance of clicking OK again to close all the open windows.
Figure 3-4. The revised Edit File Type box with your new action
That's it! Congratulations. You've created a new item on the context menu that's ready to go to work. So, now that it's there, what can you do with it?
Open up Windows Explorer. Navigate to whatever folder you want to use as the basis for the file list, and right-click to open the context menu. Click the Create File Listing item (see Figure 3-5), and the list will be generated and displayed at the bottom of the open Notepad window as filelisting.txt. Figure 3-6 shows the file listing generated from the Sample Music folder shown in Figure 3-5. Since it is a text file, it can be fully edited, copied, pasted, printed, and so on, for any purpose.
