Riding on Rails3 with full stack of Gems
NOTICE: Below post was released a month ago on Intridea Company Blog, also post here as a backup.
It’s been close to a year since Rails3 came out. Luckily, I’ve worked on several Rails3 projects after it’s released, so I’d like to share a stack of gems that I used in my previous projects. I guess they will give people a bit help while developing a new Rails3 app.
I don’t want to explain too much on these gems separately, well, most of the gems have good documents on their project wiki(every great gem should be well documented, right?). Instead, I just add regarding links to their repos so that you’d better take a further look while you really use it. In order to introduce the lists of gems clearly, I simply categorized them based on a rough structure.
Ok, here we start:
» Authentication
- OmniAuth (https://github.com/intridea/omniauth)
- Devise (https://github.com/plataformatec/devise)
The above two are really amazing gems to speed up your authentication. Yes, I love both of them in different cases: ideally OmniAuth is better for applications which want to support multi-provider external authentication, so I’ve just added OmniAuth into RefactorMyCode Rails3 branch to take its auth benefits; Devise is totally powerful enough for classic authentication case.
» Access Control
- CanCan (https://github.com/ryanb/cancan)
- declarative_authorization (https://github.com/stffn/declarative_authorization)
Ryan is a star in Rails world, so his CanCan is really popular, which aims to do neat but powerful authorization. However, the declarativeautharization is also an option, actually, Ryan mentioned CanCan was inspired by declarativeautharization.
» Views/Page and Admin Scaffold
- compass (https://github.com/chriseppstein/compass)
- haml (https://github.com/nex3/haml)
- sanitize (https://github.com/rgrove/sanitize)
- rails_admin (https://github.com/sferik/rails_admin)
- web-app-theme (https://github.com/andreferraro/web-app-theme)
From a front-end perspective, I suggest you might need to try above gems to speed up and simplify your UI designing. For example on the admin section, it’d be great if you can apply your CRUD quickly to pages, that’s what rails_admin does. Surely, these gems won’t end all your UI problems, but it really helps when you doing prototype or being lack of some real designers.
» Quick SNS
- acts-as-taggable-on (https://github.com/mbleigh/acts-as-taggable-on)
- has_friends-rails3 (https://github.com/rrouse/has_friends)
- acts_as_favable (https://github.com/yorzi/acts_as_favable)
- thumbs_up (https://github.com/brady8/thumbs_up)
- acts_as_commentable (https://github.com/jackdempsey/acts_as_commentable)
- profanity_filter (https://github.com/intridea/profanity_filter)
Well, I don’t mean a whole solution of SNS or regarding feature, here theses gems can help you add the basic cross-object function rapidly, it increases your confidence to focus on designing over programming at the very beginning. Here I want to give a simple introduction to actsasfavable, it allows for favorites refer to be added to multiple and different models.
» Form and Related Tools
- simple_form (https://github.com/plataformatec/simple_form)
- formtastic (https://github.com/justinfrench/formtastic)
- formtastic_datepicker_inputs (https://github.com/demersus/formtastic_datepicker_inputs)
- tiny_mce (https://github.com/kete/tiny_mce)
- paperclip (https://github.com/thoughtbot/paperclip)
- carrierwave (https://github.com/jnicklas/carrierwave)
Most of above gems are famous through <railscasts.com> created by Ryan. There are two pairs of options here: simple_form and formtastic / paperclip and carrierwave. I like all these solutions, you should pick up one to fit your project, if you want to know differences between each pair, get more details on their wiki :) Tiny is an HUGE gem for rich editing, I list it here to remind its exist, but I recommend you get the WYSWYG via some JS lib like CLEditor, it works gracefully.
» Searching Solutions
- meta_seach (https://github.com/ernie/meta_search)
- meta_where (https://github.com/ernie/meta_where)
- thinking-sphinx (https://github.com/freelancing-god/thinking-sphinx)
- acts_at_indexed (https://github.com/dougal/acts_as_indexed)
- sunspot (https://github.com/outoftime/sunspot)
Talking about searching in rails, I think you have many words to say. Here I wanna roughly split these gems into two types: Object-based searching and Full-Text searching. I heavily recommend you use metasearch and/or metawhere as your model based searching, it can convert your form params directly to a search solution, that’s convenient. Full-Test searching depends on your case, but all these three gems(thinking-sphinx, actsasindexed, sunspot) are great.
» Pagination
- kaminari (https://github.com/amatsuda/kaminari)
- kaminari_themes (https://github.com/amatsuda/kaminari_themes)
No more will_paginate in Rails3, absolutely, the only option is kaminari.
» Background Work
- delayed_job (https://github.com/collectiveidea/delayed_job)
- resque (https://github.com/defunkt/resque)
There is one post to introduce resque clearly here, in that post, github staff mentioned their brief history of doing background jobs, so I think you can understand well the differences between delayed_job and resque solution.
» Status Machine
- workflow (https://github.com/ryan-allen/workflow)
- state_machine (https://github.com/pluginaweek/state_machine)
I like to use workflow a bit more, since it’s much natural to me, you definitely need one status machine to control your stable flow stuff, such as a registration flow status or a wizard-like features.
» Rack API framework
This gem is for adding API to Rails/Sinatra application. Michael gave people an awesome speech in RubyConf2010 on his Grape, here I suggest you should watch it to know more details about GRAPE. I believe you will fall in love with it.
» Memcached Client
- memcache-client (https://github.com/mperham/memcache-client)
- dalli (https://github.com/mperham/dalli)
These two gems are actually mainly written by one same author Mike Perham, he mentioned that Dalli is a high performance pure Ruby client for accessing memcached servers. It works with memcached 1.4+ only as it uses the newer binary protocol. It should be considered a replacement for the memcache-client gem. The API tries to be mostly compatible with memcache-client with the goal being to make it a drop-in replacement for Rails.
» Deployment and Monitor
- capistrano (https://github.com/capistrano/capistrano)
- cap-recipes (https://github.com/nesquena/cap-recipes)
- god (https://github.com/mojombo/god)
I am not a system administrator, so every time talking about the regarding aspects will make me feel silly, I just try to describe tools which can help me out on unfamiliar area, that’s not bad, at least people like me, will do deployment and monitor quickly based on these gems, they do help.
  Now time changes, you, as a ruby programmer, can do the corn job and backup in ruby way, surely as a PRO. :)
» Testing Gracefully
- rspec-rails (https://github.com/dchelimsky/rspec-rails)
- factory_girl_rails (https://github.com/thoughtbot/factory_girl_rails)
- faker (https://github.com/yyyc514/faker)
- watchr (https://github.com/mynyml/watchr)
- autowatchr (https://github.com/viking/autowatchr)
- database_cleaner (https://github.com/bmabey/database_cleaner)
- mail_safe (https://github.com/myronmarston/mail_safe)
Testing is always important, I know TDD and BDD are getting more and more popular, that means you have to own your super gun to make it happen. Right, here is a list of gems which can help you out, I didn’t cover all different levels of testing with these gems. Point is, rspec is my favorite framework for testing, factory_girl and faker are good supports. Anyway, test by your way.
» Toolkit
- ruby-debug (https://github.com/mark-moseley/ruby-debug)
- hirb (https://github.com/cldwalker/hirb)
- cheat (https://github.com/defunkt/cheat)
- rails-settings-cached (https://github.com/huacnlee/rails-settings-cached)
There are many handy gems which will give you convenience and power. Take above four as examples, ruby-debuy gives you a chance to check your running applications’ context at specific program point; hirb display your AR items in table view in console; cheat makes your terminal working as a pool of other gems’ manual; rails-settings-cached is for global configurations in Rails3 application. Yeah, throwing the brick out is to meet your GEMS.
How to find great gems?
First, you need to follow up Ryan’s railscasts, he is good at introducing new stuff in video. Second, you can go through great open source project’s Gemfile, yeah, it’s definitely the best way to come across valuable gems. Third, just subscribe github ruby trends to know what’s going on in Ruby/Rails community. There are also some other involving sites, like rubygems and railsplugins, you should take a glance when you free, I bet you will find useful gems.
It’s nearly the end of this post, this topic was originally shared with all Intridea China Team members during last Friday Teahour. You can find the PPT here. To share with more people, I turn it into this blog, I must miss many valuable gems in this list, so please comment your thoughts.

 So do the people who make them, and the people who line up to see them. What's the point? Filmmakers keep churning them out to provide actors with a showcase to display their chops, but most are downright horrible at both pretending to die and pretending to be upset about the other person pretending to die.  Philadelphia?  And who wants to bet that the upcoming Charlize Theron/Keanu Reeves tearjerker Sweet November isn't going to be a complete waste of time? Any takers? I hope they find cures for cancer and AIDS just so film characters can stop dying.
Now, a comedy about dying people is a whole different ballgame. I'm not saying the Farrelly brothers should make a film about the Holocaust, or that the South Park guys tackling slavery would be a good idea (okay, I'd probably still be the first one in line), but there's definitely room in the marketplace for a lighthearted film about death. Two Thousand and None is that film. It's a smart, quirky and, most importantly, funny film about a normal guy who happens to be dying.
John Turturro (O Brother, Where Art Thou?) plays Benjamin Kasparian, a soon-to-be-divorced paleontologist who, as the film opens, has just discovered a new fish fossil important enough to make the science world reconsider what they know about evolution. He gets a lot of headaches and, after a visit to the doctor, learns he's got a brain-swelling disease called Talbot's Syndrome. Benjamin is given five weeks to live and is told that he may lose his memory and ability to hear.
Sounds like a blast, right? It is. Benjamin develops a sense of humor and an ability to be honest with everyone he knows and meets. His pals, co-workers and ex (played by Katherine Borowitz, Turturro's real-life wife) can't deal with Benjamin's impending death and think he's flipped his lid when he keeps trying to ditch them to have a good time with his remaining days.
As his brain swells, Benjamin begins to have cool black-and-white hallucinations in reflections of various watery surfaces (a puddle, a cup of coffee, etc.). He has imaginary conversations with his dead parents, who tell him to return their remains to Armenia. And there's a whole side plot involving the cloning of Benjamin's brain, which is simultaneously amusing and disturbing.
Two Thousand was written and directed by Arto Paragamian, who, as far as I know, used to coach football at Notre Dame. It's nice to see that he's made such a successful transition from the gridiron to the screen (yeah, I know - it was Ara Parseghian). The film, which is really made by Turturro's terrific performance, isn't too bogged down with heavy messages about the meaning of life. That is, not until the end, where Benjamin begins to confront his own mortality, and Two Thousand turns into, well, a conventional film about a guy dying.

Social Distancing Compliance (0-1)
Social distancing compliance is how seriously people adhere to Socail Distancing, which is defined by the CDC as staying at least 6 feet from other people, and avoiding gatherings. This is an effective strategy to minimize the spread of COVID-19 because the spread of COVID-19 occurs when pathogens are transmitted by respiratory droplets. Respiratory droplets can spread as far as 6 feet from their source, so when individuals are in close contact with one another, they risk spreading the disease through talking, coughing, or sneezing in particular. CDC.gov
Infection Rate (0-1)
Infection Rate is the probability that an infection will be transmitted in a population. Given that it is unclear how many people have contracted COVID-19, it is also unclear what the infection rate of COVID-19 truly is. The New York Times estimates that for every confirmed case of COVID-19, there are likely between five and ten undetected infections. U.S. News reported that after screening 3,000 people in New York, 13.9% of them tested positive.
New York Times ArticleUS News article
Fatality Rate (0-1)
Fatality Rate is the proportion of infected people that ultimately die from a disease. Given that COVID-19 is relatively new, the case fatality rate is not accurate, and the reported rates are likely too high. This is because COVID-19 is not easy to identify or diagnose, and only those that are very sick are being identified as COVID-19 positive for the most part. This makes the calculated number of infections lower than it actually is, and in turn is inflating the death rate. There are other factors that affect the case fatality rate, such as the age of a population and the strength of health systems.
NPR Article BBC Article
Test and Trace: Test Symptomatic Rate (0-1)
The Test Symptomatic Rate defines the percent of people in our simulation that are tested when they become symptomatic, and subsequently contact traced if they are infected. According to Forbes, more than 260 million of the nearly 330 citizens in the United states have an Android or iPhone smartphone. This means that in the United States, if all of these smartphone users downloaded the contact tracing app being developed by Apple and Google, nearly 80% of citizens would be participating in this advanced Bluetooth-based contact tracing platform. This type of participation in contact tracing could increase the test symptomatic rate by helping to locate people that have been exposed to the virus. Forbes Link Apple Link
Symptomatic Rate (0-1)
Symptomatic Rate refers to the probability that an infected person either shows visible symptoms as opposed to being an "asymptomatic carrier". CDC director, Dr. Redfield, estimates, as of April 2020, that 25% of people with COVID-19 may be asymptomatic. The director of the National Institute of Allergy and Infectious Diseases director, Dr. Fauci, estimates that 25-50% of people with COVID-19 may be asymptomatic. However, Medical News Today reported that it is possible that only 1-3% of people with COVID-19 are "asymptomatic carriers."

Symptom Start Time (1+)
Symptom Start Time is how long after contracting an infection the person starts having visible symptoms.Medical News Today reported on March 17, 2020 that according to a recent study, symptoms start appearing after an incubation period 2-14 days.

--- layout: post title: How to Use Web API OData to Build an OData V4 Service without Entity Framework date: 2015-03-13 03:10:41.000000000 +08:00 categories: - ".NET" - OData tutorials - OData V4 tags: [] status: publish type: post published: true author: Qian Li ---
There are quite a lot of tutorials showing how to create OData services using Web API OData, but these requires Entity Framework and a database server behind. If you want a quick try or you have your own way of implementing data sources, these tutorials may not be the best fit. In this article, we will show how to build an OData service using in-memory data as data source and with basic function.
Create a new solution following File -> New -> Project -> Web, then choose ASP.NET Web Application
. Name it with Demo
. Then in the upcoming dialogue box, choose Empty
and check Web API
, click OK.
Run the following command in the Package Manager Console.
PM> Install-Package Microsoft.AspNet.OData
In this getting-started example, we just add two model class Person.cs
and Trip.cs
under folder Models
. Person
can navigate to Trips
.
The attributes [Key]
and [Required]
are all from System.ComponentModel.DataAnnotations
meaning the property is key and required seperately.
This tutorial uses in-memory data source, which is more flexible. Below are only one way to implement, you can definitely have your only way.
Add a folder DataSource
and add a class file DemoDataSources.cs
with the code below.
Since there are two entity set, we will add two controller class under the folder Controllers
First is controller for People {% highlight csharp %} using Demo.DataSource; using System.Linq; using System.Web.Http; using System.Web.OData; namespace Demo.Controllers { [EnableQuery] public class PeopleController : ODataController { public IHttpActionResult Get() { return Ok(DemoDataSources.Instance.People.AsQueryable()); } } } {% endhighlight %}
Then is the controller for Trips {% highlight csharp %} using Demo.DataSource; using System.Linq; using System.Web.Http; using System.Web.OData; namespace Demo.Controllers { [EnableQuery] public class TripsController : ODataController { public IHttpActionResult Get() { return Ok(DemoDataSources.Instance.Trips.AsQueryable()); } } } {% endhighlight %}
In this very simple implementation, only simple Get
with query options are allowed. If you want to enable more capabilities in your controller, the code is quite similar with what's done with EF as data source. Please refer to
ASP.NET Web API OData V4 Samples and Create an OData v4 Endpoint Using ASP.NET Web API 2.2.
The last step is to modify the WebApiConfig.cs
file under App_Start
.
It's done to create a very basic OData endpoint with in-memory data source using Web API OData.
You can try it out now! All samples below are all GET
method.

Joyo's new R-15 packs 9 classic preamps into one pedal
by Rob LaingJoyo's new R-15 packs 9 classic preamps into one pedal
It's turning into a heady time to be alive for guitar players who want to play direct – either plugging in live or for recording. Following the new Strymon Iridium amp and cab modeller, Joyo has weighed in with its R-15.
It's a preamp pedal offering 9 preamp sims – each with a clean and distortion channel to give you 18 tones to tweak in total that can be switched onboard.
Though Joyo's names only allude to the famed preamp models they're based on, they include tones inspired by the Fender 65 Twin, Marshall JCM 900, Vox AC30, Mesa/Boogie Lonestar and Dual Rectifier, EVH 5150 III, Engl Powerball, Orange Thunderverb 200 and the Friedman BE-100.
There's one built in cab sim for stage use with an FX loop for additional pedals in your rig and balanced XLR output for recording.
The R-15 carries street price of $169.99 / £145. Head to Joyo for more info.

java.lang.Object com.reverseXSL.message.Data
public class Data
Wraps byte-oriented collections or structures into an object enriched with numerous methods capable of normalizing interchange data.
The original data piece (e.g. a ByteBuffer) is just wrapped, and not cloned nor copied. Therefore any later change to the argument data piece may geopardize operations.
Raw data received via some communication channel or read from various media is often affected by additional control characters, spurious record delimiters or other 'pollution' of the canonical formats required for fully automated processing. This Data class is used to wrap such raw data and yield clean, de-polluted, streams of bytes or characters for message processing.
NOTE: full use of this class is for future functional extensions of the reverseXSL software.

| Field Detail |
|---|
public static final int _1NewLineAtEnd
getConvertedData(int)
: suppress trailing empty lines
and ensure that the very last data line bears a single line terminator.
The line terminator is either CR or CRLF according to other conversions or
the existing data contents (by default).
public static final int _ASCII7bits
getConvertedData(int)
: control characters (value<32)
are discarded except for tabs, carriage returns and line feeds.
Character values above 127 are replaced by a '?'.
Note that this method operates on characters, not bytes, and thus also properly replaces all multibyte characters (whose Unicode values are always >127) with a single '?'.
public static final int _NoBlankLine
getConvertedData(int)
: suppress blank lines everywhere
in the original data. Precisely, both the
true empty lines and those containing only spaces or tabs are removed.
This is a byte-oriented method, applied before decoding bytes into characters!
public static final int _NoCRLFBytes
getConvertedData(int)
: suppress all CR's and LF's.
In other words, consider the original data as a very long line.
This is a byte-oriented method, applied before decoding bytes into characters!
It is most useful when added to_NoCtrlBytes
in which case only tab characters (with a value <32)
are preserved.
public static final int _NoCtrlBytes
getConvertedData(int)
: control BYTES (value<32)
are discarded except for tabs, carriage returns and line feeds.
8-bit values (above 127) are preserved.
This is a byte-oriented method, applied before decoding bytes into characters!
Compared with _NoCtrlChars
, the supporting function operates
on bytes and not characters, and thus may discard bytes
actually belonging to multibyte character encodings, thus scrambling the original data!.
However,
public static final int _NoCtrlChars
getConvertedData(int)
: control characters (value<32)
are discarded except for tabs, carriage returns and line feeds.
All other character values are preserved.
Compared with _NoCtrlBytes
, the supporting function preserves
character values that would be encoded as 8bit values in
ISO-8859, and all multibyte characters in
UTF-16 Unicode Transformation Formats.
public static final int _NONE
getConvertedData(int)
: case of no conversion requested.
public static final int _ToCRLF
getConvertedData(int)
: convert standalone LF's to CRLF's,
and preserve existing CRLF's.
public static final int _ToLF
getConvertedData(int)
: remove CR's.
public static final int _ToUPPER
getConvertedData(int)
: convert all characters to their
uppercase equivalents (based on built-in java String methods).
public static final int _TrimNBSP
getConvertedData(int)
: Trim
Non-Breaking SPaces (i.e. space chars and tabs) at the beginning and end of each line in the message body.
Note that if you combine this trim operation with _NoCRLFBytes
you will only trim NBSP leading and
trailing the entire data because _NoCRLFBytes transforms the whole data into a single big line first!
public static final int _UnfoldPSCRMRemarks
getConvertedData(int)
: IATA PSCRM messages still generated by older systems can enforce
the 69 chars limit of the even older TELEX transmission system by cutting lines in the middle of remarks
elements, e.g. 1BIMMEL/LMRS-BV2 .L/272397 .R/TOP KRSV .R/CKIN HK1 1BAG 05KG-1BIMMEL/LMRSbecomes:
1BIMMEL/LMRS-BV2 .L/272397 .R/TOP KRSV .R/CKIN HK1 1BAGthus breaking the .R/CKIN check-in luggage segment that normally runs to the end of line. This flag restores the canonical long line.

On my last visit to my dentist, I took a photograph of the drop ceiling above my regular chair. It is this image of curly dots and lines that serve as a point of focus while entering a heightened state of consciousness from the administered nitrous oxide.
I have done straight nitrous in the form of balloons, whippets and whipped cream canisters but the dentist office experiences are far superior due to the extended length of time and the 'safe' dosage created from mixing oxygen with the nitrous. I often use music to help insulate against the dentist's conversations with his assistant more than for the sounds and content of the music.
These N20 experiences in the dentist chairs are the most expansive states of consciousness that I have ever known. The gas seems to open a path to the immediate present. Nitrous opens the door to thoughts of the ultimate joy of life in the ever present, NOW. I believe that people find such enjoyment by realizing how good the present is, they appear to be laughing from this simple realization of joy.
The one problem I have with the gas is at times I think I may never return to a normal state of consciousness. This paranoid fear has moved me to have the dentist reduce the amount of nitrous being administered. I have also experienced a small amount of ringing in my ears after a lengthy session. Other than these mild set backs, Nitrous is amazingly fast in its onset and in its recovery time.
I have some periodontal work coming up next week. They want to charge me an additional $45.00 for administering nitrous during my treatment.

Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.


How It Works
The users can either rent any type of equipment you wish to rent or you can lend out your equipment. They can set up items they have for rent such as cameras, TVs, Party equipment like speakers/fog machines etc.
Tired of paying ridiculous fees for camera and other equipment rentals? Bypass the middleman and rent from a real person!
The users can either rent any type of equipment you wish to rent or you can lend out your equipment. They can set up items they have for rent such as cameras, TVs, Party equipment like speakers/fog machines etc.
As a renter, you will be able to save a lot of money by not needing to buy the equipment when you only need to use the equipment for a short amount of time.
As a lender, you will be able to make income by lending out your equipment to thousands of renters who really need to use the equipment but would like to save money or can't afford to buy one.
Lenders will be able to Create, Read, Update and Delete rental data. Renters can log in and see items that users have for rent and ask to rent an item.

About Me
Programming is my passion. I've been programming for 7 years in a variety of languages such as Java, C++, and Javascript and HTML. I'm especially interested in back-end programming and games. I'm an innovative, hard-working, and great at solving problems creatively. I love to experiment and try new ways of doing things, and so I'm frequently rewriting past code to try and improve on what I already have, or even just to try something new and see if it works better. I'm also a fast learner, and I'm always looking to learn new things!
I am a nonbinary individual, and my pronouns are they/them. I aim to bring diversity and a unique and different perspective to whatever team I work with in an effort to make the tech field a more welcoming and accommodating place.
I'm always working on something new, so check out my GitHub if you'd like to stay updated on my projects or see my past projects!

https://code.google.com/archive/p/pinata-csrf-tool/
Pinata is a Python Script that will generate Proof of Concept CSRF HTML from HTTP request.
Overview:
-WARNING - THIS IS NOT A POINT AND CLICK TOOL.
The tool will generate proof of concept CSRF HTML given an HTTP request. It will automatically check whether it is a GET or a POST request and with further validation for standard POST and Multipart/form POST.
The tool will then create an HTML corresponding to the type of the request.
The GET CSRF HTML includes IMG tag with SRC set to the URL being tested.
The POST CSRF HTML is created with auto submit java script form with names and values from the HTTP request.
Working:
Pinata - Version 0.93 Out Now.
Download pinata.zip from the downloads.
It is Python based tool. Needs Python installed – I have developed it on Python 2.6. But it should work with Python 2.7.
The tool consists of three files, piñata.py, markup.py and CSRFBody.txt.
To install it create a new directory like C:\Pinata and copy all three files to it.
Piñata.py is the main file and should be run to generate the HTML.
Markup.py is called by piñata.py to generate HTML, I did not develop it and do not take any credit for it - however I would like to thank the developer, it made much easier to write this tool.
CSRFBody.txt holds the HTTP request.
To use the tool go to a vulnerable page, create a request, capturing the HTTP request in the proxy. Copy this request and paste it in CSRFBody.txt, saving and closing CSRFBody.txt
Run the tool by going to command line and typing C:\Pinata\pinata.py
It should generate the HTML file in C:\Pinata\
Demonstration can be found here on my blog.
http://secmir.blogspot.com/2010/05/csrf-demo-video.html
Future Directions:
I look forward to your suggestions.
Perhaps some features to beat referer header based CSRF protection.
This is essentially a hack so I will work towards cleaning up the current code.
Questions:
Let me know if you have any questions or it suddenly stops working for you.

12.2 Quick Installation
Accessing your data
You can create and organize content in RAMADDA in a number of ways but we'll show you how to provide access
to data that is already on your server.
- Now, lets assume you have a data directory on your server, e.g., /data/ldm
- First, we need to tell RAMADDA that it is OK to provide access to that area of your file system.
- Go to the site Administration pages from the "Admin" link:
- Open the "Access " section and enter the data directory, e.g., /data/ldm, in the "File system access" field and press Change Settings:
- Now you need to create an entry that provides access to that data.
- Go to the top-level entry in RAMADDA (the "Top" link in the upper left).
- Select "New Entry" under the File menu.
- In the "Or create a" list choose Local File View and press Go:
- This will take you to the Local File View Entry create form. Enter a name, the file path and that
patterns that match the files you want to exclude. When done press "Add Local File View"
Note: If you are providing access to your LDM/IDD data feed and you are also getting the NLDN lightning data and/or the ACARS feed make sure
you exclude those directories and files.
- Congratulations you are done! To access your server from Unidata's Integrated Data View (IDV) go to the top level entry, click on the
View menu and copy the "Catalog" link into the IDV's catalog data chooser.

As we have discussed earlier, one of the major advantages of Verilog HDL is that we can define our design in any of the four levels of abstraction.
So, here we will explore how the complexity of code changes when described in various levels of abstraction and why designers prefer to describe the design at a higher level of abstraction in the case of larger designs.
In gate level modelling, the design is defined in terms of gates as basic building blocks. The module is implemented in terms of logic gates and interconnections between these gates.It is therefore termed as a low level of abstraction, as the only lower level of abstraction than gate level is the switch level modelling.
But the designs at switch level modelling (transistor switches as basic elements) can become pretty complex for even basic digital elements. Hence, gate level modelling is preferred for low levels of abstraction.
The design at this level is intuitive for the user because it is possible to see one-to-one correspondence between logic circuit diagrams and their Verilog codes. A change in the value of any input signal of a component activates the component. If two or more components are activated simultaneously, they will perform their actions simultaneously as well.
We are already familiar with the Gate Predefined Primitives and how we implement basic logic and transmission gates in Verilog HDL. Also, we’ve got a basic idea how to define a module for any digital system we wish to design.
To learn/revise concepts of Gate Primitives, refer Predefined Primitives
Here, we would like to implement a basic digital system in Gate Level Modelling with the help of these gate primitives.
Most logic gates have delays associated with them depending on signal transition (Rise, Fall and Turn Off Delays). Each of these delays can be in three forms: ‘Min’, ‘Max’ and ‘Typical Values’, depending upon the configuration. A user can specify these delays in gate models in Verilog HDL by following a certain syntax. Modelling these gates exactly as per their properties gives us an edge of obtaining practical and reliable results.
We’ll be discussing this in depth with examples in Gate-Level Modelling.
For smaller circuits the gate level modelling seems to work fine, as the number of gates is limited and connecting every gate individually is not a big issue. But in complex designs , it is not efficient to follow the gate level modelling as the number of gates is pretty large.
To solve this problem, Dataflow Modelling provides a powerful way to implement the design at higher levels of abstraction. The circuit is designed in terms of how data flows between registers and how the design processes the data. The style of modelling is similar to implementation of Boolean logical equations. It comprises expressions where input signals are assigned to output signals along with some operations to be done.
There are a lot of tools developed for converting the final expressions to a gate level implementation, basically getting the final circuit diagram in terms of gates and wires.
The most basic statement in dataflow modelling is a continuous assignment. This assignment replaces gates in the circuit implementation.
The assignment syntax starts with the keyword ‘assign’ followed by the signal name which can be either a single signal or a concatenation of different signals.
Syntax ---
assign (net_expression) =[drive_strength] [delay](expression of different signals and operators or constant values)
The drive_strength and delay parameters are optional and are used when real hardware needs to be implemented. In addition to all of this, we also need to know about various types of assignments and operators.
This might seem complex, but don’t worry! We’ll be discussing this in depth with relevant examples in Dataflow Level Modelling.
With more and more complexity in digital design, designers need to be able to evaluate the trade-offs of various algorithms and architecture to get the optimum algorithm and architecture in the end. All these things are possible when hardware implementation is designed at an algorithmic level and not with dataflow or logic gates
Verilog HDL provides designers the ability to describe the design functionality in an algorithmic manner, basically describing the behaviour of the circuit. The behavioural description is therefore, the highest level of abstraction. The design at this level resembles the C programming language, as a lot of constructs are similar to C language in many ways. The style of modelling is similar to implementation of Truth Tables or similar digital blocks which describe the behaviour of the circuit. It is the closest to a natural language description of the circuit functionality, but at the same time, it is the most difficult to synthesize
The basic statements in this type of modelling are termed as Structural Procedures which include the keywords ‘always’ and ‘initial’. These are expressed in terms of blocks which contain behavioural statements. Multiple such behavioural statements can be grouped with keywords ‘begin’ and ‘end’, just like the curly brackets {} in C Language.
The behavioural statements are in the form of procedural assignments.
Conditional Statements and Loop Statements are also used to represent the behaviour of certain blocks.
Sequential Circuits are best modelled in this level of abstraction. It is a very important topic in the learning process of Verilog HDL, and hence is quite lengthy. This is because most of the large-scale designs are based in Behavioural Modelling. The reason is very simple, it describes the design in a much effective and effortless manner.
A detailed explanation on Behavioral Modeling is presented in Behavioural Modelling

Modules are used to expand the capabilities of class and develop super classes. They also segeregate classes of the same name into modules.They allow for different inheritance patterns. Modules are used to expand the capabilities of an entire program and avoid redundancy. They are much more effective than saving the same files to a folder like in C programming.

Self awareness
17 April 2016
Mindfulness is about paying attention to something, only observing and being aware of it without judging or looking for meaning.
Self awareness is another step after mindfulness. Self awareness is being crtically reflective of oneself's emotions, thoughts and actions, understanding oneself without attachment.
The practice of mindfulness helps us become more self aware. By paying attention to ourselves without judgement, we are able to reflect ourself and be self aware.
This week, a practice I tried from the book was a body scan. I've done less directed, shorter, body scans in the past. I experienced the same relaxation and calming as I have done in the past. Something I did not expect was the joy felt when I recognised that my mind had been wandering. I couldn't place why I felt joy but it often occurred as I regained my focus.
The concluding part of the body scan was to entertain a positive memory and then focus on how the body responds to this memory. This part was less enjoyable as it was difficult for me to focus on a positive memory without remembering negative things linked to it. It felt a little like dredging up the past, feeling less immersive than an in-the-moment attention.
An insight given at the end of the reading was "my emotions are not me". Thinking about emotions as an experience allows me to be aware of them without getting caught up with them. It is a simple but curious idea that will help me internally verbalise emotions from "I am anxious" to "I experience a feeling of anxiousness". I believe this will help in letting emotions go.

EDIT: Alright, we now have started a Geo group for Phoenix AZ. It is a google group at http://www.phxgeo.org. We are going to have monthly meetups every 2nd Wednesday of the month location TBD. The group encompasses everything geo from GIS to programming.
OK, so I have looked all over for a Python user group in Arizona and I cannot find anything. So many states have users groups but I cannot find anything. As big of a city that Phoenix is, I find this unbelieveable. Not only is there not a Python users group in Arizona but there is also no GIS user group. What is up with this? All of the other states have something going on but we do not in Arizona. In the programming world I have found so many people willing to assist in helping and we are in one of the largest cities in the U.S.
If there is anybody that knows of a Python or GIS users group in Arizona, please let me know. If there isn't anything out there but somebody would like to start a user group for Python or GIS, please let me know.

class Logger
Description¶ ↑
The Logger
class provides a simple but sophisticated logging utility that you can use to output messages.
The messages have associated levels, such as INFO
or ERROR
that indicate their importance. You can then give the Logger
a level, and only messages at that level or higher will be printed.
The levels are:
UNKNOWN
-
An unknown message that should always be logged.
FATAL
-
An unhandleable error that results in a program crash.
ERROR
-
A handleable error condition.
WARN
-
A warning.
INFO
-
Generic (useful) information about system operation.
DEBUG
-
Low-level information for developers.
For instance, in a production system, you may have your Logger
set to INFO
or even WARN
. When you are developing the system, however, you probably want to know about the program's internal state, and would set the Logger
to DEBUG
.
Note: Logger
does not escape or sanitize any messages passed to it. Developers should be aware of when potentially malicious data (user-input) is passed to Logger
, and manually escape the untrusted data:
logger.info("User-input: #{input.dump}") logger.info("User-input: %p" % input)
You can use formatter=
for escaping all data.
original_formatter = Logger::Formatter.new logger.formatter = proc { |severity, datetime, progname, msg| original_formatter.call(severity, datetime, progname, msg.dump) } logger.info(input)
Example¶ ↑
This creates a Logger
that outputs to the standard output stream, with a level of WARN
:
require 'logger' logger = Logger.new(STDOUT) logger.level = Logger::WARN logger.debug("Created logger") logger.info("Program started") logger.warn("Nothing to do!") path = "a_non_existent_file" begin File.foreach(path) do |line| unless line =~ /^(\w+) = (.*)$/ logger.error("Line in wrong format: #{line.chomp}") end end rescue => err logger.fatal("Caught exception; exiting") logger.fatal(err) end
Because the Logger's level is set to WARN
, only the warning, error, and fatal messages are recorded. The debug and info messages are silently discarded.
Features¶ ↑
There are several interesting features that Logger
provides, like auto-rolling of log files, setting the format of log messages, and specifying a program name in conjunction with the message. The next section shows you how to achieve these things.
HOWTOs¶ ↑
How to create a logger¶ ↑
The options below give you various choices, in more or less increasing complexity.
-
Create a logger which logs messages to STDERR/STDOUT.
logger = Logger.new(STDERR) logger = Logger.new(STDOUT)
-
Create a logger for the file which has the specified name.
logger = Logger.new('logfile.log')
-
Create a logger for the specified file.
file = File.open('foo.log', File::WRONLY | File::APPEND) # To create new logfile, add File::CREAT like: # file = File.open('foo.log', File::WRONLY | File::APPEND | File::CREAT) logger = Logger.new(file)
-
Create a logger which ages the logfile once it reaches a certain size. Leave 10 “old” log files where each file is about 1,024,000 bytes.
logger = Logger.new('foo.log', 10, 1024000)
-
Create a logger which ages the logfile daily/weekly/monthly.
logger = Logger.new('foo.log', 'daily') logger = Logger.new('foo.log', 'weekly') logger = Logger.new('foo.log', 'monthly')
How to log a message¶ ↑
Notice the different methods (fatal
, error
, info
) being used to log messages of various levels? Other methods in this family are warn
and debug
. add
is used below to log a message of an arbitrary (perhaps dynamic) level.
-
Message in a block.
logger.fatal { "Argument 'foo' not given." }
-
Message as a string.
logger.error "Argument #{@foo} mismatch."
-
With progname.
logger.info('initialize') { "Initializing..." }
-
With severity.
logger.add(Logger::FATAL) { 'Fatal error!' }
The block form allows you to create potentially complex log messages, but to delay their evaluation until and unless the message is logged. For example, if we have the following:
logger.debug { "This is a " + potentially + " expensive operation" }
If the logger's level is INFO
or higher, no debug messages will be logged, and the entire block will not even be evaluated. Compare to this:
logger.debug("This is a " + potentially + " expensive operation")
Here, the string concatenation is done every time, even if the log level is not set to show the debug message.
How to close a logger¶ ↑
logger.close
Setting severity threshold¶ ↑
-
Original interface.
logger.sev_threshold = Logger::WARN
-
Log4r (somewhat) compatible interface.
logger.level = Logger::INFO # DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN
-
Symbol or String (case insensitive)
logger.level = :info logger.level = 'INFO' # :debug < :info < :warn < :error < :fatal < :unknown
-
Constructor
Logger.new(logdev, level: Logger::INFO) Logger.new(logdev, level: :info) Logger.new(logdev, level: 'INFO')
Format¶ ↑
Log messages are rendered in the output stream in a certain format by default. The default format and a sample are shown below:
Log format:
SeverityID, [DateTime #pid] SeverityLabel -- ProgName: message
Log sample:
I, [1999-03-03T02:34:24.895701 #19074] INFO -- Main: info.
You may change the date and time format via datetime_format=
.
logger.datetime_format = '%Y-%m-%d %H:%M:%S' # e.g. "2004-01-03 00:54:26"
or via the constructor.
Logger.new(logdev, datetime_format: '%Y-%m-%d %H:%M:%S')
Or, you may change the overall format via the formatter=
method.
logger.formatter = proc do |severity, datetime, progname, msg| "#{datetime}: #{msg}\n" end # e.g. "2005-09-22 08:51:08 +0900: hello world"
or via the constructor.
Logger.new(logdev, formatter: proc {|severity, datetime, progname, msg| "#{datetime}: #{msg}\n" })
not used after 1.2.7. just for compat.

The block should return an Object that can be written to the logging device via write
. The default formatter is used when no formatter is set.
Logging severity threshold (e.g. Logger::INFO
).
Program name to include in log messages.
Logging severity threshold (e.g. Logger::INFO
).
Public Class Methods
Args¶ ↑
logdev
-
The log device. This is a filename (String) or IO object (typically
STDOUT
,STDERR
, or an open file). shift_age
-
Number of old log files to keep, or frequency of rotation (
daily
,weekly
ormonthly
). Default value is 0, which disables log file rotation. shift_size
-
Maximum logfile size in bytes (only applies when
shift_age
is a positive Integer). Defaults to1048576
(1MB). level
-
Logging severity threshold. Default values is Logger::DEBUG.
progname
-
Program name to include in log messages. Default value is nil.
formatter
-
Logging formatter. Default values is an instance of
Logger::Formatter
. datetime_format
-
Date and time format. Default value is '%Y-%m-%d %H:%M:%S'.
binmode
-
Use binary mode on the log device. Default value is false.
shift_period_suffix
-
The log file suffix format for
daily
,weekly
ormonthly
rotation. Default is '%Y%m%d'.
Description¶ ↑
Create an instance.
# File lib/logger.rb, line 379 def initialize(logdev, shift_age = 0, shift_size = 1048576, level: DEBUG, progname: nil, formatter: nil, datetime_format: nil, binmode: false, shift_period_suffix: '%Y%m%d') self.level = level self.progname = progname @default_formatter = Formatter.new self.datetime_format = datetime_format self.formatter = formatter @logdev = nil if logdev @logdev = LogDevice.new(logdev, shift_age: shift_age, shift_size: shift_size, shift_period_suffix: shift_period_suffix, binmode: binmode) end end
Public Instance Methods
Dump given message to the log device without any formatting. If no log device exists, return nil
.
# File lib/logger.rb, line 484 def <<(msg) @logdev&.write(msg) end
Args¶ ↑
severity
-
Severity
. Constants are defined inLogger
namespace:DEBUG
,INFO
,WARN
,ERROR
,FATAL
, orUNKNOWN
. message
-
The log message. A String or Exception.
progname
-
Program name string. Can be omitted. Treated as a message if no
message
andblock
are given. block
-
Can be omitted. Called to get a message string if
message
is nil.
Return¶ ↑
When the given severity is not high enough (for this particular logger), log no message, and return true
.
Description¶ ↑
Log a message if the given severity is high enough. This is the generic logging method. Users will be more inclined to use debug
, info
, warn
, error
, and fatal
.
Message format: message
can be any object, but it has to be converted to a String in order to log it. Generally, inspect
is used if the given object is not a String. A special case is an Exception
object, which will be printed in detail, including message, class, and backtrace. See msg2str for the implementation if required.
Bugs¶ ↑
-
Logfile is not locked.
-
Append open does not need to lock file.
-
If the OS supports multi I/O, records possibly may be mixed.
# File lib/logger.rb, line 458 def add(severity, message = nil, progname = nil) severity ||= UNKNOWN if @logdev.nil? or severity < level return true end if progname.nil? progname = @progname end if message.nil? if block_given? message = yield else message = progname progname = @progname end end @logdev.write( format_message(format_severity(severity), Time.now, progname, message)) true end
Close the logging device.
# File lib/logger.rb, line 571 def close @logdev&.close end
Returns the date format being used. See datetime_format=
# File lib/logger.rb, line 284 def datetime_format @default_formatter.datetime_format end
Set date-time format.
datetime_format
-
A string suitable for passing to
strftime
.
# File lib/logger.rb, line 279 def datetime_format=(datetime_format) @default_formatter.datetime_format = datetime_format end
Log a DEBUG
message.
See info
for more information.
# File lib/logger.rb, line 493 def debug(progname = nil, &block) add(DEBUG, nil, progname, &block) end
Sets the severity to DEBUG.
# File lib/logger.rb, line 310 def debug!; self.level = DEBUG; end
Returns true
iff the current severity level allows for the printing of DEBUG
messages.
# File lib/logger.rb, line 307 def debug?; level <= DEBUG; end
Log an ERROR
message.
See info
for more information.
# File lib/logger.rb, line 545 def error(progname = nil, &block) add(ERROR, nil, progname, &block) end
Sets the severity to ERROR.
# File lib/logger.rb, line 331 def error!; self.level = ERROR; end
Returns true
iff the current severity level allows for the printing of ERROR
messages.
# File lib/logger.rb, line 328 def error?; level <= ERROR; end
Log a FATAL
message.
See info
for more information.
# File lib/logger.rb, line 554 def fatal(progname = nil, &block) add(FATAL, nil, progname, &block) end
Sets the severity to FATAL.
# File lib/logger.rb, line 338 def fatal!; self.level = FATAL; end
Returns true
iff the current severity level allows for the printing of FATAL
messages.
# File lib/logger.rb, line 335 def fatal?; level <= FATAL; end
Log an INFO
message.
message
-
The message to log; does not need to be a String.
progname
-
In the block form, this is the
progname
to use in the log message. The default can be set withprogname=
. block
-
Evaluates to the message to log. This is not evaluated unless the logger's level is sufficient to log the message. This allows you to create potentially expensive logging messages that are only called when the logger is configured to show them.
Examples¶ ↑
logger.info("MainApp") { "Received connection from #{ip}" } # ... logger.info "Waiting for input from user" # ... logger.info { "User typed #{input}" }
You'll probably stick to the second form above, unless you want to provide a program name (which you can do with progname=
as well).
Return¶ ↑
See add
.
# File lib/logger.rb, line 527 def info(progname = nil, &block) add(INFO, nil, progname, &block) end
Sets the severity to INFO.
# File lib/logger.rb, line 317 def info!; self.level = INFO; end
Returns true
iff the current severity level allows for the printing of INFO
messages.
# File lib/logger.rb, line 314 def info?; level <= INFO; end
Set logging severity threshold.
severity
-

, do nothing for IO. Default isnil
.
Description¶ ↑
Reopen a log device.
# File lib/logger.rb, line 412 def reopen(logdev = nil) @logdev.reopen(logdev) self end
