The MySQL adapter will work with both Ruby/MySQL, which is a Ruby-based MySQL adapter that comes bundled with Active Record, and with the faster C-based MySQL/Ruby adapter (available both as a gem and from www.tmtm.org/en/mysql/ruby/).
Options:
By default, the MysqlAdapter will consider all columns of type tinyint(1) as boolean. If you wish to disable this emulation (which was the default behavior in versions 0.13.1 and earlier) you can add the following line to your environment.rb file:
ActiveRecord::ConnectionAdapters::MysqlAdapter.emulate_booleans = false
| LOST_CONNECTION_ERROR_MESSAGES | = | [ "Server shutdown in progress", "Broken pipe", "Lost connection to MySQL server during query", "MySQL server has gone away" ] |
| QUOTED_FALSE | = | '1', '0' |

Only the True Friends Fans Will Know What Went Wrong With Jennifer Aniston’s Quiz
by Devon IvieRachel and Jill are back on yet another late-night blitz for that show they’re promoting, and, like a lotion and a powder creating an anti-leather paste, you know exactly what’s destined to happen: Friends trivia. The questions are easy and the guests are into it (we’ll just spoil that Julie Andrews declares “THEY WERE ON A BREAK!”), so we’ll posit another question for the show’s diehards instead. There’s a wrong answer that was deemed correct. What was it? Maybe it was Jennifer Aniston reminiscing about the British trifle. Or Reese Witherspoon fondly recalling her one good line about lactose intolerance. We guess life is gonna be this way for them, forever.


Victoria Beckham says she and husband David are equal partners in parenting
It's no wonder David and Victoria have got it right as they have been married for nearly two decades
by Irishmirror.ieVictoria Beckham reckons she and husband David have perfected parenting.
The fashion designer said the parents take it in turns when it comes to looking after their four kids during her Tuesday appearance on Jimmy Kimmel.
Posh Spice and David raise their children Brooklyn, 20, Romeo, 17, Cruz, 14, and Harper, seven, together.
In a loving moment, Victoria celebrated her husband's successes as she praised him for being a "very good dad".
She said: "I've been married to him for over 20 years, so I'm kinda fond of him. He's a good dad, he's a very good dad...
"He's really good, I mean. David is watching the kids and we swap. When I'm at home, he's away, so one of us is always there looking after the kids."
It's no wonder David and Victoria have got it right as they have been married for nearly two decades.
Recently, the Beckham brood spent Halloween in Los Angeles with David while Victoria was busy with work.
The mother-of-four discussed the famous family's wide connections in the US.
Close to Justin Bieber and his new wife Hailey, David took Harper for a magical trick or treating session at the singer's home.
Victoria explained how the special evening come about.
She said: "He texted David, this was on Halloween, he asked what David was doing, he was out trick or treating with the kids.
"[Justin] said “Come over, I’m giving out snow cones”. He's such a nice man."
Victoria is in Los Angeles this week to launch her Cell Rejuvenating Prime Moisturizer.
She has been focusing on the launch of her beauty brand as she continues to expand her image in the fashionable spheres.

Usage¶
Collect Python files¶
Collecting Python files is really straight forward:
from pycollect import PythonFileCollector
collector = PythonFileCollector()
files = collector.collect()
Note
By default, files are collected from the current execution’s working directory.
At each collect()
call a custom search path can be specified:
from pycollect import PythonFileCollector
collector = PythonFileCollector()
files_foo = collector.collect("../foo")
files_bar = collector.collect("../bar")
Note
Search paths can be either, relative or absolute. Relative directories are not referring to the declaration file’s location as root but to the current working directory.
Beyond default exclusion patterns for file and directory names the
PythonFileCollector
class accepts additional patterns:
from pycollect import PythonFileCollector
collector = PythonFileCollector(
additional_file_exclusion_patterns=["*_test.py", "foo*", "Bar_*qux.py"],
additional_dir_exclusion_patterns=["*tests", "test*"],
)
files = collector.collect()
Note
By default the simple pattern syntax is used to match file and directory names.
The *
character is considered a wildcard and can be used only once per pattern.
The !
character at the beginning of the pattern negates it.
Note
Regex syntax can be enabled instead of the simple pattern syntax passing
regex=True
as parameter to the PythonFileCollector
. This may impact
collection time performance though.
Find a file’s Python module¶
Given a file one can easily find its referring Python module using the
find_module_name()
utility method:
from pycollect import find_module_name
module_name = find_module_name("/path/to/file.py")
Note
As a file can refer to multiple modules, by default, the outermost module found is
returned. This behavior can be inverted by passing innermost=True
as parameter
to find_module_name()
.

TASK FORCE SPARTAN
i. The Command Staff would like you to know that our office is not one of power, but of responsibility. It is our duty to steer the course of this unit to greatness. That said the power and might of this unit is YOU! We can not do great things without you and your dedication. We look forward to you and the talent you can bring to this group.
i. Within Task Force Spartan, we believe highly in personnel following the in-place chain of command. Our front line of leadership are the FTLs and SLs within the unit. We believe in the idea that such personnel are in the prime position to assist with and deal with any issues that may arise during a member's time with TFS. With this, it is expected that any issues within the unit are first given to a member's immediate leadership personnel, who will if necessary, continue the issue further up the chain-of-command. While every member values the opinion of every other member, regardless of rank, we want to ensure that those within the lower levels of leadership are as active with the average members as possible, and are the next link in the chain to higher command.
i. Task Force Spartan enforces a zero tolerance policy regarding any sort of disrespectful behavior or mischief. Nobody should be back talking other members, and especially NCOs and Officers, given they have been granted this trust and position, and must be shown respect.
ii. Indecently talking back to authority will be valid grounds for a dishonorable discharge or other means of disciplinary action taken against the offender(s). Our reason for uniting as a unit of this scale is, that we intend to run as a mil-sim unit, and all hope to have fun and a good time. With this comes following the orders of your superiors.
*Every member is to be treated equally, and nobody should be disrespecting anyone!
i. Task Force Spartan will be built as an Army unit and as such will follow the standard element make up. We operate at the Company level and Detachments will operate at the Platoon level.
Task Force Command
Battalion Commander [LTC]
Battalion Executive Officer[MAJ]
Battalion Sergeant [CSM]
Company Commander[CPT]
Company Sergeant [1SG]
Detachments
Platoon Leader[2LT]
Platoon Sergeant[SFC]
Below is a breakdown of elements from the smallest to the largest to help you understand unit composition.
iii. As a Task Force often times we will blend these structures for the benefit of the group. As we do not have the funding or manpower of a nation we will make do and adjust when needed.
i. TFS members will be promoted based on the training's and skills they have earned at certain events. Some promotions require you to be selected(Billet). These ranks will be based on actions and attitude you have displayed in the unit!
ii. Leadership is to be inquisitive and apply critical thinking in regards to promotions. To be promoted at higher levels of leadership, one must receive three recommendations. Rank is to be provided based on competence and performance. Re-evaluation of current leadership will happen over time.
i. This unit operates on a basis of mutual respect and one facet of this respect is of each member's time and commitment to the unit. The command staff requires weekly roll calls regarding attendance for operations. Responding you cannot attend an operation is perfectly understandable as real life happens, we just ask that you communicate with your leaders about your situation. If for some reason you cannot attend for an extended period of time, we have a process for requesting a LOA (Leave of Absence), LOAs are for times when you will be gone for more than 2 weeks or 2 operations.
ii. Failure to respond to roll call or failing to attend an operation in which you committed to attending will result in an unexcused absence. Below is the process for unexcused absences.
i. By becoming a member of Task Force Spartan, all members are subject to disciplinary actions decided upon by that persons detachment command and/or unit command. This can include but is not limited to inappropriate conduct, blatant harassment, racism, disrespecting other unit members, etc. Such disciplinary actions can include but are not limited to probation, inability to attend an event, demotion, dismissal from the unit, etc. Any person found not following such restrictions made or are not willing to abide by punishments made will be subject to immediate dismissal with no ability to reapply.
i. Training at Task Force Spartan is divided into three separate bands: Fundamentals, Specializations, and Leadership. The first band includes Basic Combat Training, Advanced Individual Training, and MOUT. These classes provide the combat essentials for a member of Task Force Spartan to be successful. From there, focus is put into explaining specialty roles and equipment. These classes are Advanced Weapons Training, Airborne/Air Assault, Medical Training, and Convoy Training. Finally, Radio Communications and Leadership Training reflect the skills necessary to operate within the unit in a leadership role. By the time a member has completed all facets of training, they are expected to be able to understand and utilize all roles within a fire team effectively, utilize specialty weapons, equipment, and vehicles, as well as be able to manipulate radios to facilitate proper communication at the platoon level and above.
ii. Their will be no Make-up training's or side training’s unless permitted by all of Company Command. Training is only part of the requirement for rank, and review is also required. 3 individuals should sign off on promotions and should prepare comments, personal and from peers, about the individual being evaluated.
iii. Platoon training's will be done every two weeks, squad training's can be done whenever and however much but there must be a minimum of four hours a month of squad training.
i. To be considered for retirement certain criteria must be met. Member must have served honorably and have earned the rank of Sergeant, Chief Warrant Officer Two, or Second Lieutenant. A formal letter of retirement will be placed and will be either accepted or denied by Command staff.
ii. Retired members will retain the privilege of their rank, but will not but authorized to exert command over active members. After one month returning to the active roster will require a refresher training. If the retiree is to join another unit, they will lose all positions with TFS.
i. If you bring your issues to leadership and they are not resolved promptly you are authorized to bring them to the next higher leader. If it is not resolved there please inform the Command Staff. If leaders are not available the requester will not be at fault. *You must have followed the chain-of-command before going to higher leadership!
i. Every member of Task Force Spartan is expected to show maturity and professionalism at all times, regardless of the server they are present on. “Fun Ops” are permitted, but irregular messing about and disrespect towards fellow players and especially leaders will incur disciplinary actions. All NCO’s/CO’s (CPL’s and above) are to be referred by their ranks!
ii. Leaders (CPL and above) are required to maintain order and decency on the operation server, and especially for these “Fun Ops”. While anyone (within reason) could be running Zeus and create the operation, the NCOs and COs are responsible for leading as per the command structure of Task Force Spartan – the highest ranking leader present must act as being in command of the operation, and must inform the next link in the chain of command if issues occur.
iii. Fun operations will be done in MOS gear unless otherwise stated by the highest ranking NCO during the planning of the mission.
iv. Pilots, Vehicle Commanders, Squad Leaders, Platoon Headquarters positions (2LT, SFC, RTO, Medic) can have Commander’s Tablets, FTLs may have androids. Global markers may only be placed by platoon leadership and above before the company moves out. After that, markers may only be placed in the commander's tablet or direct chat.
iv. Choose your voice volume appropriately (i.e whisper, normal, yelling), do not stay on yelling all the time, cater it to how far the guys you are talking to are. If someone breaks this rule, it should be pointed out to them.
*Should extreme or most unusual circumstances arise, notify Company Command immediately.
i. All higher ups are to act serious at all times, if somebody is acting out or breaking policy any higher up is allowed to discipline to an appropriate level. Any issue must be reported to the offender’s CO/NCO.
ii. COs and NCOs are required to maintain order and decency on the operation server, and especially for these “Mini Ops”. While anyone (within reason) could be running Zeus and create the operation, the NCOs and COs are responsible for leading as per the command structure of Task Force Spartan – the highest ranking leader present must act as being in command of the operation, and must inform the next link in the chain of command if issues occur.
i. Poking is not an acceptable form of official communication, only private messages through the forum are permitted.
ii. People must ask permission from the owner of the office if they may enter, NOT the highest rank in the channel. If the owner is not present then the highest rank may be asked.
iii. Training and Deployment rooms must never be signed into whether it be active or inactive. If a game channel is being used for arma purposes do not join the TS channel until you are in game with TFR connected. If you have question on the mini operation please message the commander(Highest ranking) in the channel.
iv. Radio protocol must always be used in TFS events.
v. Highest rank must be given admin immediately upon joining the server.
vi. Attention will be called by the highest ranking person in the channel when an officer enters the channel. At ease will be called by the highest ranking person in the channel when an SFC or above enters a channel. If there is a person with a higher rank in the channel already nothing is called. This does not apply to warrant officers.

“On Thursday morning, he awoke heavy, confused and splenetic. On Friday, he remembered a friend's prescription that, on arising, he should cut two or three brisk capers round the room, which he did and found attended with most agreeable effects. It expelled the phlegm from his heart, gave his blood a free circulation and his spirits a brisk flow, so that he was all at once made happy. He resolved to persist in the exercise.”

The Sweet Hereafter (1997) * * * * A movie review by Serdar Yegulalp Copyright 1998 by Serdar Yegulalp
THE SWEET HEREAFTER is not the first film I have cried in, but certainly one of the few where I felt unashamed of what I was being invited to weep over. This is one of the best films ever made about the uncertainty of how to live in the face of death and tragedy. it is not a tearjerker that works with dumb gimmicks like a terminal disease or a cute animal; it simply states a condition, with merciless detail, and asks that we empathize. We do. It is one of the best films about "the human condition" -- what a weatherbeaten way to talk about life and death! -- since Kurosawa's IKIRU.
Somewhere in Canada, a township has suffered a terrible accident. A busload of fourteen schoolchildren went off the road, and all of them save two -- one student and the driver -- were killed. A lawyer, Mitchell Stephens (Ian Holm, in easily the best performance he has ever given), comes to this town to represent the citizens in a class action suit. Maybe they can get something back -- not their children, certainly (and one of the citizens tells him, bluntly, that there's nothing Stephens can do for him unless he can raise the dead), but something is better than nothing, yes?
Stephens is himself in mourning for his own child. His daughter is not dead, but a drug addict, and in a way that's worse -- he gets to hear her voice without being able to do anything to really help her, since she's proven time and again that she's not trustable. The first time we see him, he's locked in a car wash, talking to his daughter on the cell phone. She is stuck in some unnamed city, trying to hustle him for more drug money. He mouths one nicety after another mechanically. Holm's performance is fearful and excellent, and only one of several excellent ones in this film.
The movie is not a formula legal thriller where everything hinges on some plot twist or piece of hidden evidence, but rather a story about pain that cannot be healed or dispelled with social mechanisms like lawsuits. The parents of some of the surviving children are depicted in spare, carefully assembled scenes. Some of them are hungry for any chance at redemption at all, like the parents of the adopted Indian boy (Earl Pastko and Arsinee Khanjian). Some are bitter and numb, like the father who witnessed the accident (Bruce Greenwood). Some have lost just enough to know they are not the only ones suffering, like the parents (Tom McCamus and Brooke Johnson) whose talented daughter is now confined to a wheelchair for life.
Nicole (Sarah Polley), the girl singer, is a pivotal character, but for reasons that sneak up on us gradually. At first we think her character is just going to be another meditation on soldiering on through life, no matter what we're given, but the accident has done more than cripple her -- it's starved her of a whole group of friends and peers. (The movie uses the poem "The Pied Piper" to great and tragic effect here -- a device that sounds corny, but strikes like a hammer blow when its real meaning surfaces.) She is lonely, and wounded because of that. Her performance, too, is excellent -- she's not so emotionally distant that we feel annoyed for wanting to empathize with her in the first place.
The story is drawn from a novel by Russell Banks, who had four of the main characters tell the story in separate monologues. The director, the gifted Atom Egoyan, has chosen to take the book apart and reassemble it in a way that jumps back and forth through time, but he does not use black and white vs. color or other cheap cinematographic tricks to discern the past from the present. He simply lets each scene dictate its presence in the story's whole through its emotional resonances, through what is shown and what is only implied, and the result is incredibly nuanced and rich.
One of the ways we see the movie expose itself piece by piece is in a series of scenes that take place on the flight back from the town. Here, Holm's character confesses a great deal about his daughter to a friend -- and in a scene of utterly astounding emotional power, talks about when his daughter almost died of an insect bite when she was a baby, and how he was confronted with the possibility of having to perform an emergency tracheotomy on her with a pocketknife. The way this scene is deployed and the way Ian Holm's voice ties it together and pushes it forward is masterful and heartbreaking, not the least of which because he has saved her life before and now finds himself saying about her, "I gave her all the love the father of a drug addict could spare."
The film is also startlingly lovely. I had the chance to read the script before seeing the movie, and wondered: Would this just be a movie where the characters sit around and talk to each other? No; the town is seen in elegantly composed shots that are like Wyeth paintings. Egoyan has filmed everything in a way that makes the events stand out starkly and brilliantly on the screen, and has managed to find the colors in everything he points the camera at without being flashy or distracting. The only indulgence he permits himself is in the very last shot, and by that time he's earned it.
And then there are those final scenes, in which we see the whole sad affair of the lawsuit disintegrating as a key witness apparently falsifies a testimony. Why? Since this is not a movie with a lockstep, closed-ended plot, it's almost unfair to ask a question like that. Some things cannot be healed, the movie seems to be saying, and must simply be turned away from. But some of us, sadly, cannot turn away, and are blinded as we look on.

Not the greatest, but I've found some of its snippets useful. If you really want to learn, get an intro book from B&N.

3D Graphics programming is going to be a really pain in the bum unless you first understand some of the concepts. Jumping into Direct3D 9 without any theory on:
a) 3D Math/Space
b) 3D -> 2D conversions
c) API <-> OS <-> Graphics Hardware
...is going to leave you wondering what the hell just went on to make that triangle appear on the screen. Direct3D 9 isn't a very beginner-friendly API and assumes you have already passed Calculus III and have been programming with 3D graphics for a long time (= steep learning curve).
It certainly isn't impossible, but without a book or some other formal writing, it will be much more difficult to learn.

Probably a good choice. There are times when I wished I had learned it first, but both DX and OpenGL have their ups and downs (please don't start a discussion on the specifics)

no problem. I am pretty good at decypering C++ errors, but if you want more help with OpenGL, Figgles is the person to ask. He really knows what he's talking about.

The reason that code doesn't work very well is because it uses a library called glaux, which is OpenGL Auxilliary which is an optional library that came with the original OpenGL for Windows 95 (i.e. software rendering) that was vastly ignored.
Unfortunately, that library has been deprecated for close to a decade now and didn't even ship in Windows 98. It doesn't do much, just loads some images really. I suggest that you find a tutorial that doesn't require glaux. I think the site Karl mentioned ,www.ultimategameprogramming.com, has tutorials on how to load images without glaux.

Sundowns book spot in TKO final with victory over Arrows
Mamelodi Sundowns’ dominance over Golden Arrows in their semi-final clash of the Telkom Knockout cup was mirrored by the final score.
by Phakaaathi ReporterLindokuhle Mtshali of Golden Arrows and Hlompho Kekana of Mamelodi Sundowns during the Telkom Knockout 2019 Semi Final match between Golden Arrows and Mamelodi Sundowns at Sugar Ray Xulu Stadium on November 23, 2019 in Durban, South Africa. (Photo by Anesh Debiky/Gallo Images)
Coach Pitso Mosimane’s men managed to score two goals in the first half to seal the victory against the home side at the Sugar Ray Xulu Stadium.
Sundowns captain Hlompho Kekana opened the scoring for the defending Absa Premiership champions before Gaston Sirino extended the Brazilians’ lead.
Sirino went from hero to villain when he was given a straight red car for a late tackle in the 83rd minute.
Nduduzo Sibiya pulled one back for the KZN side to give coach Steve Komphela’s men hope of making a comeback.
Arrows missed an injury-time chance to take the game into extra time with a ten men Sundowns team but Mosimane’s men held on for the victory.

[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!]
After hearing all this hype about weed and how it's so awesome. I wanted to try it to get high and have fun. My friend and I went out and bought some and we decided to smoke after a while. So later on, we went back to her house and rolled the joints. She's a regular smoker, and we went outside to smoke it. I smoked mine and didn't feel anything, she didn't want hers anymore so I smoked hers too. I've never tried it before or any other types of drugs except for smokes.
I didn't feel anything while I was smoking my joint, so then when she offered me hers, I accepted because I thought I just needed more. But after like 5-10 mins I started to really feel the effects. I knew I was high and it's not like when you're drunk and you're having fun. It feels so much different. It made me paranoid, I thought I was going to die because my heart was pounding so hard. And I just remember I wanted the high to go away so badly. My friend and I were in her basement and we spent the majority of the night trying to calm me down. She was telling me she felt the same thing when she first smoked and that it was normal. But I didn't believe her.  I was just saying to myself 'you're high, just act normal' and for the 2 seconds I felt like I was normal but couldn't help it. I definitely wasn't peaceful or happy at all.
I just wanted to go home to sleep and have everything back to normal. So that was my plan, I got my keys and drove home. MY friend was telling me to take the leftover weed but that was the last thing that I wanted I am surprised I made it home. But I was scared shitless of getting caught so I was super careful and slow. I went home and went into bed. I started freaking out even more, saying to myself that I was going to die.  I just wanted to enjoy the high and not feel paranoid. And I kept telling myself to just be happy, and relax. It worked on and off for a few seconds but it got the better of me. I think the main thing that gave me a bad trip was my expectancy. I was expecting to just feel mellow, happy, and light headed. But instead my heart was pounding badly, and I didn't think that was normal. If somebody would have told me that, I would have been more prepared.
So after a few weeks, I wanted to try it again. It was definitely better the second time. I knew that my heart was going to pound, but it didn't so much because I think it was in my head more the first time. And I felt happy, but I was alone, so I didn't really have any bad cases of laughs. I just chilled and ate some stuff, and I had a shower and never wanted to get out. I went out with a friend and was able to control myself. And the high lasted probably about 2 hours. The first two hours are probably the worst, well they are the most extreme where you don't remember anything, where you can't control yourself, where you are really high. But then it's worth it because after that for another hour or two you feel like medium high were you are just happy and not so paranoid. I think that's what I'll feel like more when I smoke it more.
But overall, I just thought weed would make you feel like when you're drunk. I like the feeling of being drunk better (maybe it has something to do with the fact that it's a depressant) but I don't like drinking, smoking is just easier.

{{ site.contact_name }}
IT professional with a track record in increasing the rate at which teams can safely deliver customer value. I specialise in automating release processes, building the tools and fostering the culture that shifts quality and security left.
As a generalist, I am driven by a need to understand and own the end-to-end delivery of solutions both new and legacy; partly to achieve the best outcome for clients, but also to keep my technical curiosity in check!
Career Summary
I started out working part-time as a support engineer/junior dev for an internal J2EE-based product at ServiceRocket, while completing my Bachelor of IT at UTS. After graduating, I moved to the consulting team at ServiceRocket, selling, speccing and delivering process improvements, migrations and custom add-on development for the Atlassian ALM tools, and then tossing them over the 'wall' to customers ops teams.
Craving the satisfaction of longer-term ownership and continuous longer-term feature delivery, I moved to Transport for NSW, first building out a greenfield platform to deliver a revamped, cloud native update to their primary customer facing digital property transportnsw.info, and then operating and improving the platform and website in production for a year and a half. While at Transport, I co-operatively ran the Sydney Atlassian User Group (now ACE) events for a year to stay connected with my Atlassian product roots, doing event planning, hosting and delivering a few talks when community speakers were not available.
2018 brought about a move to London, where I started my consultancy, Digital Frontiers. The first engagagement with WorldFirst brought me into the ops sysadmin territory I had missed by jumping straight from development to the self-healing immutable infrastructure and serverless solutions we ran at Transport.
At WorldFirst, I continously delivered and supported software on bare-metal KVM hosts running in co-lo datacentres for the first 6 - 12 months. I then took a second engagement, which utilised my prior public cloud experience and knowledge of WorldFirst's production systems to provide technical leadership for a successful public cloud migration. A final engagment followed, where I led the updates and re-certification of IT BCP/DR plans for the new cloud platform.


1 Background
Flume is an open-source Apache project, it is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. This article shows how to import XML Files with Flume, including the development of a deserializer plugin and the corresponding configurations of Flume. We are using Flume 1.5.0 integrated with MapR.
The secenario is that XML files are sychronized to a directory periodically, we need to config a Spooling Directory Source to load these XML files into Flume.
2 Implement a Flume Deserializer
The default deserializer of Flume’s Spooling Directory Source is LineDeserializer, which simply parses each line as an Flume event. In our case, we need to implement a deserializer for XML files based on the structure.
2.1 Programming Environment
I prefer Gradle as the build automation and Eclispe as the IDE for java programming. Make sure you have them installed.
1. Create a folder for the project and create a build.gradle file using the template below.
2. Add dependencies to the build.gradle.
1 2 3 4 5 6 7 8 | @@ -25,6 +25,8 @@ repositories { dependencies { //compile 'commons-collections:commons-collections:3.2' + compile 'org.apache.flume:flume-ng-sdk:1.5.0' + compile 'org.apache.flume:flume-ng-core:1.5.0' testCompile 'junit:junit:4.+' } |
3. Initialize source folders and the Eclipse project.
1 | $ gradle initSourceFolders eclipse |
4. Import the project to Eclipse and now you can start coding.
2.2 Development
Custom deserializer has to implement EventDeserializer interface. We need to read input stream from ResettableInputStream and output a list of Event through readEvents() function.

नेब्रास्का मराठी मंडळ
is excited to present this first issue of the quarterly newsletter to you all. This is an effort of the Mandal to keep its members informed about upcoming activities, any new developments within the member community and lots of other things. It will also reflect on the past events and its success. As you might know, NMM was established with the aim to bring together individuals and family who share the Marathi culture. From its beginning the Mandal has made significant strides in bonding the members in its community. Its ever growing members list and increasing attendance at every event is a validation of the efforts that the Mandal committees/volunteers have put forth. NMM has been able to generate tremendous enthusiasm within the Maharashtrian community in Nebraska. We are seeing new faces at every event and growing list of member volunteers. Kudos to existing members for making every event a success and also keeping up the communication.


Run
Generate, transform, or validate configuration files using locally run functions.
Functions are packaged as container images, starlark scripts, or binary executables which are run against the contents of a package.
Get an overview on how to use kpt fn run
from the Running Functions guide.
This page dives into details of the kpt fn run
command flow and serves as a
reference for advanced usecases.
Synopsis
kpt fn run DIR [flags]
If the container exits with non-zero status code, run will fail and print the
container STDERR
.
DIR:
Path to a package directory. Defaults to stdin if unspecified.
Examples
# read the Resources from DIR, provide them to a container my-fun as input,
# write my-fn output back to DIR
kpt fn run DIR/ --image gcr.io/example.com/my-fn
# provide the my-fn with an input ConfigMap containing `data: {foo: bar}`
kpt fn run DIR/ --image gcr.io/example.com/my-fn:v1.0.0 -- foo=bar
# run the functions in FUNCTIONS_DIR against the Resources in DIR
kpt fn run DIR/ --fn-path FUNCTIONS_DIR/
# discover functions in DIR and run them against Resource in DIR.
# functions may be scoped to a subset of Resources -- see `kpt help fn run`
kpt fn run DIR/
Structured Results
Functions may emit results using the structure defined in the
typescript result interface as an alternative to exiting with a non-zero
status code. Users may want to store these results separately from
configuration files. Kpt provides the --results-dir
flag for users to
specify a destination to write results to.
Example: Run validate-rolebinding
on an example package
kpt pkg get https://github.com/GoogleContainerTools/kpt-functions-sdk.git/example-configs example-configs
mkdir results/
kpt fn run example-configs/ --results-dir results/ --image gcr.io/kpt-functions/validate-rolebinding:results --<EMAIL_ADDRESS>Network Access
By default, container functions cannot access network. kpt
may enable network
access using the --network
flag, and specifying that a network is required in
the functionConfig.
Example: Run kubeval
on a package
apiVersion: v1
kind: ConfigMap
metadata:
name: my-config
annotations:
config.k8s.io/function: |
container:
image: gcr.io/kpt-functions/kubeval
network:
required: true
config.kubernetes.io/local-config: 'true'
kpt pkg get https://github.com/instrumenta/kubeval.git/fixtures .
kpt fn source fixtures/*invalid.yaml |
kpt fn run --fn-path fc.yaml --network 2>error.txt || true
Mounting Directories
By default, container functions cannot access the local file system. kpt
may
enable functions to mount volumes using the --mount
flag passing the same
arguments as for docker run
.
Example: Run kustomize-build
on a helloWorld package
kpt pkg get https://github.com/kubernetes-sigs/kustomize/examples/helloWorld helloWorld
kpt fn source helloWorld |
kpt fn run --mount type=bind,src="$(pwd)/helloWorld",dst=/source --image gcr.io/kpt-functions/kustomize-build -- path=/source |
kpt fn sink .
All volumes are mounted readonly by default. Specify rw=true
to mount volumes
in read-write mode.
kpt pkg get https://github.com/kubernetes-sigs/kustomize/examples/helloWorld helloWorld
kpt fn source helloWorld |
kpt fn run --mount type=bind,src="$(pwd)/helloWorld",dst=/source,rw=true --image gcr.io/kpt-functions/kustomize-build -- path=/source |
kpt fn sink .
kpt
accepts the same options to --mount
specified on the Docker Volumes
page.
Depending on the container image, the configuration function may not have permissions to access mounted volumes. Check how the function is running inside the container in case of permissions issues.
Environment Variables
kpt
exports all local environment variables except the TMPDIR
variable
when launching a docker container. Check the value of any environment
variables that are declared locally as they may be affecting container
behavior.
# Check the value of the GOPATH environment variable
echo $GOPATH
# List all environment variables
env
Deferring Failure
When running multiple validation functions, it may be desired to defer failures
until all functions have been run so that the results of all functions are
written to the results directory. Functions can specify that failures should be
deferred by specifying deferFailure
in the declaration.
apiVersion: example.com/v1alpha1
kind: ExampleFunction
metadata:
annotations:
config.kubernetes.io/function: |
container:
image: gcr.io/example.com/image:v1.0.0
# continue running functions if this fails, and fail at the end
deferFailure: true
Imperative Run Specifics
Generating FunctionConfig for Imperative Runs
When functions are run imperatively, the functionConfig will be generated from command line arguments.
When functions are run using the below command, the key-value pairs following
--
are parsed into a ConfigMap which is set as the functionConfig. The
arguments are passed as data
elements in the ConfigMap.
Example: Run validate-rolebinding
on an example package
kpt pkg get https://github.com/GoogleContainerTools/kpt-functions-sdk.git/example-configs example-configs
mkdir results/
kpt fn run example-configs/ --results-dir results/ --image gcr.io/kpt-functions/validate-rolebinding:results --<EMAIL_ADDRESS>Function Input:
kind: ResourceList
functionConfig:
apiVersion: v1
kind: ConfigMap
data:
subject_name<EMAIL_ADDRESS>...
items:
...
If the first argument after --
is not a key=value pair, it will be used as
the functionConfig type.
Run the function:
kpt fn run DIR/ --image foo:v1 -- Foo a=b c=d
Function Input:
kind: ResourceList
functionConfig:
kind: Foo
data:
a: b
c: d
...
items:
...
Caveats to Running Imperatively
kpt does not handle imperatively running functions which use the following types of arguments.
Complex arguments
Functions may take complex arguements such as lists and maps that have nested fields. It’s recommended to run such functions declaratively.
Arguments interpreted as flags
Some functions like helm-template
, istioctl-analyze
, and kustomize-build
take arbitrary command line flags as arguments. Passing arguments such as
--use-kube=false
imperatively results in parsing issues. See more details in
the following:
When passing flags as arguments, it’s recommended to run functions declaratively.
Functions expecting spec field
kpt fn run
provides any arguments passed imperatively to the container image
in a ConfigMap
containing a data
field. Some config functions may expect
arguemnts passed in a spec
field instead. It’s recommended to run such
functions declaratively by passing a ConfigMap
with a spec
field. See more
details in the following:
Declarative Run Specifics
Scoping Rules
Functions which are nested under some sub directory are scoped only to Resources under that same sub directory. This allows fine grain control over how functions are executed.
kpt fn run DIR/
will recursively traverse DIR/ looking for declared functions
and invoking them – passing in only those resources scoped to the function.
Example: Function declared in stuff/my-function.yaml
is scoped to
Resources in stuff/
and is NOT scoped to Resources in apps/
.
├── stuff
│ ├── inscope-deployment.yaml
│ ├── stuff2
│ │ └── inscope-deployment.yaml
│ └── my-function.yaml # functions is scoped to stuff/...
└── apps
├── not-inscope-deployment.yaml
└── not-inscope-service.yaml
Alternatively, you can also place function configurations in a special
directory named functions
.
Example: This is equivalent to previous example
.
├── stuff
│ ├── inscope-deployment.yaml
│ ├── stuff2
│ │ └── inscope-deployment.yaml
│ └── functions
│ └── my-function.yaml
└── apps
├── not-inscope-deployment.yaml
└── not-inscope-service.yaml
Alternatively, you can also use --fn-path
to explicitly provide the directory
containing function configurations:
kpt fn run DIR/ --fn-path FUNCTIONS_DIR/
Alternatively, scoping can be disabled using --global-scope
flag.
Multiple Functions Ordering
Functions execution follows a deterministic order and is based on the following set of rules:
- If the functions are specified in the same file
(multi-object YAML file separated by
---
), they will be executed sequentially in the order that they are specified. - If the functions are specified in multiple files, the functions deeper in the file system tree are executed first.
- If the functions are specified in multiple files but are at same file system tree depth, the function in the file with shorter lexical file path is executed first.
Example: Directory structure with multiple functions and corresponding ordering
.
├── stuff
│ ├── deployment.yaml
│ ├── stuff2
│ │ └── deployment.yaml
│ │ └── my-function3.yaml # executed first
└── └── my-function1.yaml # executed second
└── my-function2.yaml # executed third
Custom functionConfig
Functions may define their own API input types - these may be client-side equivalents of CRDs:
Example: Declare two functions in DIR/functions/my-functions.yaml
apiVersion: v1
kind: ConfigMap
metadata:
annotations:
config.kubernetes.io/function: |
container:
image: gcr.io/example.com/my-fn
data:
foo: bar
---
apiVersion: v1
kind: MyType
metadata:
annotations:
config.kubernetes.io/function: |
container:
image: gcr.io/example.com/other-fn
spec:
field:
nestedField: value
--flag-arg: flag-value
Because the first function uses the default ConfigMap
kind with arguments as
key-value pairs in the data
field, kpt is able to run it both imperatively
and declaratively. kpt is only able to run the second function declaratively
because:
- it expects arguments in the
spec
field - it takes complex arguments with nested values
- it takes flags as arguments

The memorial estate Arkhangelskoye
Yusupov burial vault (“The Colonnade”)
Yusupov burial vault (“The Colonnade”) is the latest building constructed in estate of Arkhangelskoe. It was constructed in 1909 – 1916 by the last owners Zinaida and Felix Yusupov in memory of their son Nikolas who lost his duel and died 22 of June 1908. Such kind of building is not typical to Russian architecture of the beginning of the XX century.
It is built in neo-classic style upon the project of R. Klein's, the famous Moscow architector. Yusupov burial vault is located in south-eastern part of the park near the old Church of Archangel Michael, the vault is situated on the place of former barley building. One can find some similarities between the Yusupov burial vault and St. Peter's Basilica in Rome or Kazan Cathedral in Petersburg: centrally-planned building with portico, dome, rounded collonade wings and balustrade around an oval ground.
Foundation works started in spring 1909.
Internal space of the vault is divided in 3 levels: top level is a Saint Nicholas's church with a chancel apse; on the ground level there is a burial vault (similar to a chapel); and a “crypt” (burial chamber) on the lowest level . The top interior is magnificently ornamented with vegetative and geometric frescos with some elements of religious Christian art (angels, cherubs, crosses) and fretwork. The lower interior is treated in monochromatic and geometric style. Accurate proportions create unique acoustics of the interior.
In 1912 the facade and the interior were redecorated. Klein's student, Grigory Brahinin, executed the works on constructing the bas-relief from a drawing by Klein.
Craftsmen Gladkov and Kozlov worked with sculptures and fretwork details on building facade, bas-reliefs on the dome drum, colomn caps, they undertook works on redecoration of the cornice and portico. Interior fretwork details were made by craftsmen of the first Moscow sculpture and fretwork workshop. Moscow firm “Artur Perks and co” laid the floor with multicolored tiles (made of marble crumb) upon Klein's drawing.
In 1913 Klein invited famous expert of monumental-decorative arts Ignatiy Nivinskiy to draw frescoes. The works have not been finished because of the First World War started in 1914 and the Russian Revolution in 1917. Yusupov family at first had to emigrate to Italy and then to France. So, the vault have never been used.
Today the building is used as an open storage of the large-scaled picture of Jusupov family's collection and also as an exhibition hall.

Talented Ghanaian Jeremie Frimpong tipped to be worth “£20m in two years”
Ghanaian youngster Jeremie Frimpong has been tipped to reach a valuation of £20million within the next two years if he continues showing his fine form.
According to Football Insider, a source close to Celtic has revealed that the club’s coaching staff have been seriously impressed by the former Manchester City man since his arrival in the summer.
Furthermore, the report also claims they believe the full-back could be “worth £20million in two years if he keeps his feet on the ground.”
Frimpong has certainly hit the ground running at Celtic, and he has been incredibly impressive in his five appearances for the club so far.
While it appears too early to stick such a price tag on the 18-year-old, the raw potential he possesses is there for all to see.
And if he remains as level-headed as he appears to currently be, then there is no reason why he can’t reach the top level and become a great player for Celtic.

| PostgreSQL 9.5.19 Documentation | |||
|---|---|---|---|
| Prev | Up | Appendix B. Date/Time Support | Next |
Ordinarily, if a date/time string is syntactically valid but contains out-of-range field values, an error will be thrown. For example, input specifying the 31st of February will be rejected.
During a daylight-savings-time transition, it is possible for a seemingly valid timestamp string to represent a nonexistent or ambiguous timestamp. Such cases are not rejected; the ambiguity is resolved by determining which UTC offset to apply. For example, supposing that the TimeZone parameter is set to America/New_York, consider
=> SELECT '2018-03-11 02:30'::timestamptz; timestamptz ------------------------ 2018-03-11 03:30:00-04 (1 row)
Because that day was a spring-forward transition date in that time zone, there was no civil time instant 2:30AM; clocks jumped forward from 2AM EST to 3AM EDT. PostgreSQL interprets the given time as if it were standard time (UTC-5), which then renders as 3:30AM EDT (UTC-4).
Conversely, consider the behavior during a fall-back transition:
=> SELECT '2018-11-04 02:30'::timestamptz; timestamptz ------------------------ 2018-11-04 02:30:00-05 (1 row)
On that date, there were two possible interpretations of 2:30AM; there was 2:30AM EDT, and then an hour later after the reversion to standard time, there was 2:30AM EST. Again, PostgreSQL interprets the given time as if it were standard time (UTC-5). We can force the matter by specifying daylight-savings time:
=> SELECT '2018-11-04 02:30 EDT'::timestamptz; timestamptz ------------------------ 2018-11-04 01:30:00-05 (1 row)
This timestamp could validly be rendered as either 2:30 UTC-4 or 1:30 UTC-5; the timestamp output code chooses the latter.
The precise rule that is applied in such cases is that an invalid timestamp that appears to fall within a jump-forward daylight savings transition is assigned the UTC offset that prevailed in the time zone just before the transition, while an ambiguous timestamp that could fall on either side of a jump-back transition is assigned the UTC offset that prevailed just after the transition. In most time zones this is equivalent to saying that "the standard-time interpretation is preferred when in doubt".
In all cases, the UTC offset associated with a timestamp can be specified explicitly, using either a numeric UTC offset or a time zone abbreviation that corresponds to a fixed UTC offset. The rule just given applies only when it is necessary to infer a UTC offset for a time zone in which the offset varies.


Previous: Partial instances, Up: Background [Contents][Index]
The previous sections pretend that there is only one kind of request in HTTP — the ‘GET’ request. In fact, there are some others.
The ‘HEAD’ request method retrieves data about an resource. Polipo does not normally use ‘HEAD’, but will fall back to using it for validation it if finds that a given server fails to cooperate with its standard validation methods (see Cache transparency). Polipo will correctly reply to a client’s ‘HEAD’ request.
The ‘POST’ method is used to request that the server should do something rather than merely sending an entity; it is usually used with HTML forms that have an effect3. The ‘PUT’ method is used to replace an resource with a different instance; it is typically used by web publishing applications.
‘POST’, ‘PUT’, ‘OPTIONS’ and ‘DELETE’ requests are handled by Polipo pretty much like ‘GET’ and ‘HEAD’; however, for various reasons, some precautions must be taken. In particular, any cached data for the resource they refer to must be discarded, and they can never be pipelined.
Finally, HTTP/1.1 includes a convenient backdoor with the ‘CONNECT’ method. For more information, please see Tunnelling connections.
Polipo does not currently handle the more exotic methods such as ‘PROPFIND’.
HTML forms should use the ‘GET’ method when the form has no side-effect as this makes the results cacheable.


Getting Started¶
So you want to give Keydra a go? Here’s how you deploy it to an AWS account with a starter secret under management.
You will need¶
An AWS account. Don’t have one, free tier is fine! Go get a free one at https://aws.amazon.com/free !
An Atlassian Bitbucket or a Github account, to host your Keydra configuration. We only support Bitbucket and Github right now, but expect to add other code repository providers in the future.
Initial Deployment¶
Setup a configuration repository¶
Create a new private repository, clone it locally, and change to the new directory. See the relevant guide for your preferred platform option:
Create a new directory called config, and initialise your environments and secrets files. We’ll start with one AWS environment (i.e. account) called main, and one sample secret called sample.
mkdir config && cd config
touch environments.yaml secrets.yaml
Edit environments.yaml. This file tells Keydra about the AWS account it will deploy to, and which secrets to manage there.
dev:
description: Our Development AWS account
type: aws
access: dev
id: <your AWS account ID>
secrets:
- sample
For this example, we’ve told Keydra that this account is a dev one, but could also be production or uat. The sample line tells Keydra to manage that secret in this environment, which we’ll now define! You can add lots of environments (i.e. AWS accounts) to this file, just follow the same format and append.
Edit secrets.yaml. This file tells Keydra about our secrets, just one for the time being - update with your repo organisation or user name, and update the provider key to match your code repo type. Note that the repository name here needs to be all lower case.
Note
What is the custodians key all about? This is just a free text value that can be used to indicate which person/team is the ‘owner’ of this secret. Can be handy in a larger environment where secrets are not managed by one central team.
sample:
key: keydra_managed_sample
description: A example secret which exists in IAM
custodians: my_team
provider: IAM
rotate: nightly
config:
groups:
- MyDeploymentGroup
policies:
- a/path/PolicyName
distribute:
-
config:
repository: keydraconfiguration
account_username: <your repo org or user name>
scope: repository
envs:
- dev
key: AWS_ACCESS_KEY_ID
provider: <bitbucket OR github>
source: key
-
config:
repository: keydraconfiguration
account_username: <your repo org or user name>
scope: repository
envs:
- dev
key: AWS_SECRET_ACCESS_KEY
provider: <bitbucket OR github>
source: secret
Now push your config up to the repo.
git add .
git commit -m "Initial commit"
git push origin main
What have we setup? This secret will create/manage an IAM user, which we’ll rotate the password every night, and distribute the key and secret as two environment variables in our new code repository. Why would you do this? You could use these credentials in pipelines to deploy code to AWS. Rather than hardcoding these values in your repo, this way Keydra will ensure that they are:
using your least privilege deploy IAM group (MyDeploymentGroup, which we’ll create soon)
are changed (very!) frequently to limit impact if compromised/exposed
are not seen by sneaky humans that can put them onto sticky notes or sell on the dark web!
Deploy Keydra to AWS¶
On your local machine, clone the Keydra role and install dependencies. Always best to create/activate a Python virtualenv first, but will leave that up to you.
git clone https://github.com/Athena-Home-Loans/keydra.git
cd keydra
pip install -r requirements-dev.txt
pip install -r src/requirements.txt
Friends don’t let friends use admin for everything!! Login to your AWS account console, and create a new IAM user called keydra_deploy, with programmatic access only and a policy like that in docsrc/KeydraDeploy.json.
Create an access key for the keydra_deploy user and stash the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY as enviroment variables in your terminal.
Now, we’re going to use AWS SAM to deploy two CloudFormation stacks. The first one (keydraExecRole) sets up a least privilege role to run Keydra with. Execute the following on your local machine, changing the region to match your needs.
Note
We’ve added some additional restrictions to this sample role. This requires all Keydra managed secrets in AWS Secrets Manager to be tagged with “managedby: keydra”. If this annoys you, delete lines 52-54 to provide Keydra will perms to all secrets.
sam build -t docsrc/KeydraExecRole.yaml
sam deploy -t docsrc/KeydraExecRole.yaml --stack-name keydraExecRole --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND CAPABILITY_NAMED_IAM --region ap-southeast-2
Assuming the SAM run was successful, you should see an outputs block with an Arn for the new role. Note this down, we’ll need this for step 7.
Now we’ll create the second stack, this one for keydra itself. Copy docsrc/sample_template.yaml to your main Keydra directory as template.yaml. This is a nice SAM template that will make this easy!
cp docsrc/sample_template.yaml template.yaml
Edit template.yaml. This looks daunting, but you only need to change the 6 values in angle brackets.
IAM Role Arn - This is the ARN to an AWS IAM role that you’ll use to run Keydra, from step 5.
repo account name - The code repo account or organisation name from the first section.
secrets repo name - The repository name. In this example, this is KeydraConfiguration.
path to secrets.yaml - The path to our secrets. For our example, this is src/main/config/secrets.yaml for Bitbucket, or main/config/secrets.yaml for Github.
environments repo name - We’ll use the same repo, use KeydraConfiguration.
path to environments.yaml - The path to our environments definition. For our example, this is src/main/config/environments.yaml for Bitbucket, or main/config/environments.yaml for Github.
Build and deploy with SAM. Make sure Docker is installed/running first!
sam build --use-container
sam deploy --stack-name keydra --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND --region ap-southeast-2
Test Run¶
Let’s do an adhoc trial run of the lambda!
In the AWS Console, navigate to the Lambda service.
You should see a keydra function, open it up.
- Scroll down a little, and select the Test tab. Test with the following event, which tells Keydra to run a Nightly run
with debug enabled. Click the Test button to run Keydra.
{
"trigger": "nightly",
"debug": true
}
With a little luck, you should see something like this!
- What just happened? Keydra created an IAM user in AWS, and then stored the IAM username and password in two separate
repository variables in your code repository. You can see the results under your repo; browse to Repository settings > Repository variables in Bitbucket, or Settings > Secrets in Github.
You can now use these values to deploy your code to AWS, and Keydra will kindly rotate them automagically every night, without you needing to do a thing!


TimeMe.js
You have been active on this page for
0 seconds
Demo
Notice the timer above? It is tracking how long you are actively viewing this web page.
 It also stops incrementing if you go idle for more than 5
seconds (meaning you don't move the mouse or enter the keyboard for 5 seconds). While 5
seconds is a relatively short time to gauge inactivity, it can be increased to a more
realistic value (such as 60 seconds) to determine that a user is no longer viewing the page
and has left the browser or computer altogether.
Tracking specific elements
TimeMe allows you to track how users are interacting
with specific elements on
your page. If you go idle, the timer also stops.
Interact with this element
Interaction: seconds.
Interact with this element
Interaction: seconds.
TimeMe.js
TimeMe.js is a JavaScript library that accurately tracks how long users interact with a web page.
It disregards time spent on a web page if the user minimizes the browser or
switches to a different tab. This means a more accurate reflection of actual 'interaction' time by
a user is being collected.
Additionally, TimeMe.js disregards 'idle' time outs. If the user goes
idle (no page mouse movement, no page keyboard input) for a customizable period of time,
then TimeMe.js will automatically ignore this time. This means no time will be reported where a web page
is open but the user isn't actually interacting with it (such as when they temporarily leave the computer).
Furthermore - TimeMe supports tracking time for specific elements within a page. This means you
can track and compare usage of different parts of the same web page. Multiple concurrent timers
are supported.
These components put together create a much more accurate representation of how
long users are actually using a web page.


Located on the SE corner of the island, this is a safe and protected harbour. It is no longer used commercially. Only the Coast Guard have a base here.
Position 17°51.6' N, 076°19.5 W.
See Jamaica Formalities for full details re. clearing into and out of Jamaica.
Although this is officially a Port of Entry it may not be the best place to try and clear into Jamaica. It's likely you will be charged to bring the officials from Kingston for clearance (approx. US$65).
Last updated January 2016.
Anchor in front of the Coast Guard station. If it is free, they may suggest that you berth at their dock. They are very friendly and welcoming. The dock was originally a small marina which went out of business. It has water available.
The small town of Morant Bay is across the harbour and the approach is very shallow for the last 100m or so. It has a small restaurant.

Getting started¶
Where are we going?¶
We mentioned Machine Learning on the workshop land page —here’s a figure that provides a little more perspective. Note the emphasis on sample size “rules of thumb”. This is a characteristic of the empirical and computational nature of machine learning that enables the use of complex and sensitive models which subsequently require large amounts of data to actualize meaningful (as opposed to spurious) model fits. The figure also gives an indication of the vast and diverse set of tools and tasks that make up the machine learning world. If you’re interested in exploring this fascinating methodology space and learning how to leverage and apply these powerful tools (which, since you’re here, you probably are), then you’re going to need a fundamental understanding and serviceable skill set in programming, probability and statistics. And if you’re just starting your journey (congratulations!!) you’re in the right place!
http://scikit-learn.org/stable/tutorial/machine_learning_map
Industry Leading Tools¶
The above figure is part of Scikit-Learn’s extensive documentation and tutorial collection. Scikit-Learn is the leading open source collection of machine learning tools. There are some competitors (notably R, which has seen an increase in machine learning capabilities, but is still tailored more towards the more historical statistics and traditional data analysis communities), but it is safe to say that Scikit-Learn is the industry standard bearer. Scikit-Learn is a library in the python programming language – another industry standard in terms of programming languages – which has seen widespread adoption and the establishment of an incredibly vast and diverse ecosystem. Python is, and has been for quite some time now, the hottest most generally useful program language around. If you’re looking to build up your programming skill set, you cannot go wrong Python. One final industry leader is the Anaconda framework from Continuum Analytics. Anaconda is a platform that simplifies package management and deployment of open source data science capabilities. Data Scientists Love Anaconda.
Installing Python¶
Because (a) Python is the working language of the Data Science Immersive, and because (b) you’ll need to have a installation of Python on your computer if you want to follow along with the examples in this work shop, we encourage you to install Anaconda (which comes with a working installation of Python out of the box).
Installing an Editor¶
Data scientists need to be proficient at programming. To do this there is a specific kind of editor that is commonly used. There are many editors to choose from… Unless you have a programming editor that you are already comfortable with we recommend that you start with VSCode.
Another alternative for a beginner level editor is Atom.
Note
Programming practices, editors, version control, software engineering, and other related topics are not part of the scope of this short course.
Installing Git (optional)¶
On windows¶
Download the latest Git for Windows installer
When you’ve successfully started the installer, you should see the Git Setup wizard screen
Important
To use Git from the command prompt you must check the box
Open a Command Prompt (or Git Bash if that functionality was not enabled)
On OSX¶
Install Brew (If it is not already installed) using the instructions here
Install git from the command line
~$ brew install git
On Ubuntu¶
~$ sudo apt install git
Keeping your materials up to date¶
If you have Git installed on your machine. cd into the directory on your machine and
~$ git pull
If you are not using Git:
Copy the any downloaded materials you might have into a backup directory
Download the zip file from the repository and uncompress it
At the end of the course you may wish to fork the repository to your personal GitHub.
A note on Jupyter¶
Jupyter notebooks are a way to mix interactive Python with prose as expressed using Markdown. They are also both very powerful and an industry standard so practice with them is useful.
An in-depth understanding of Jupyter notebooks is not necessary for this course, but they are frequently used so it can be helpful to become familiar with the technology. Here are some resources to help you better understand this computing environment.


Narrated Abu Abs:
I heard the Prophet saying, "Anyone whose feet are covered with dust in Allah's cause, shall be saved by Allah from the Hell-Fire."
Narrated Abu Huraira:
heard Allah's Apostles (p.b.u.h) saying, "If the prayer is started do not run for it but just walk for it calmly and pray whatever you get, and complete whatever is missed. "
Narrated Abdullah bin Abi Qatada on the authority of his father:
The Prophet (p.b.u.h) said, "Do not stand up (for prayer) unless you see me, and observe calmness and solemnity".
