Mapping For More Than Just Directions
Finding Your Way From E..e In Your Enumerables
Friday, June 12, 2015
Ruby is an awesome language. Just this week I managed to take a 35 line method that I had written for a challenge and refactor it down into just 3 lines. That's including the def and end lines! How was I able to do this you might ask? The magic of Ruby's many built-in methods! It is one of these magical methods that I will be spending the rest of this post talking about. That's right, no food talk, just method talk. Namely, #map
, or Enumerable#map
if you wish.
So, what can #map
do for you? Before we get into that, let me quickly point something out. While #map
is really cool and totally worth writing an entire post about, it isn't exactly unique. You see, #collect
is the exact same thing! Despite this, it is still an incredibly useful, and potentially powerful, tool.
Ok, now we can get into what #map
actually does. What better way to start than with a simple example? Let's say you have a large array of name tat you are going to use at some point in your program. Unfortunately, this array was populated via the keyboard input of a fellow human. As a result, some names are in all lowercase, some have stray capitals in, and others still are in all caps for some reason (maybe it was getting close to lunch time, hanger is real!). Anyway, before we can do anything else with this array we should fix all that. Let's start with the zeroth element, see that it is "Janet", move on to the first element, notice "jason"...what? Oh yes, much too slow! Ok, let's set up a while
loop and go through each elemen...now what? Just get to the #map
already? Gee, as you wish. All of this can easily be done with one line of code!
names_array.map! {|name| name.capitalize}
Just like that, your name_array
will be filled with nicely capitalized names! You may have noticed the "!" after map? That nifty little variation on the standard #map
method ensures that your names not only get changed, but that they stay changed. That's right, your original array will be changed! If that isn't something you want to do, just leave that "!" off. The #map
method will then just return the changed array so that you can store it or chain it into other methods as you see fit.
Now that we have a brief idea as to what #map
can do, let's quickly look at the syntax involved in calling it and maybe touch a bit on what is actually happening. First, the syntax. For an array, the syntax is as follow:
array_to_be_mapped.map {|element| #code to be done to element}
So, here we are working with our wisely named array_to_be_mapped
. Each element of array_to_be_mapped
will be passed into the provided code block, temporarily being assigned to the variable element
. The result of this call will be an array containing the results of the code being called on each element of array_to_be_mapped
. For those that like to see the actual code in action:
> ary = [1, 2, 3, 4]
=> [1, 2, 3, 4]
> ary.map {|n| n * 3}
=>[3, 6, 8, 12]
> ary
=> [1, 2, 3, 4]
Each number in the array was yielded to the block of code as n
and multiplied by 3, resulting in the array [3, 6, 9, 12]
. The original array was never changed, as is shown in the last two lines above. Finally, let's take one last look at the alternate, or multi line, syntax for map along with how it can be used with a hash
.
Keeping with our example above, we have the below hash showing two our of groups (notice the names are beautifully capitalized):
my_hash = {"Group 1" => ["Max", "Ben", "Erin", "Stacie", "Erick"],
"Group 2" => ["Philip", "Brenda", "Andrew", "Harmin", "Daniel"]}
But, what if we want each group to have their names in alphabetical order? We have already split them up, and they're no longer in one giant array that we could run #sort
on so...#map
to the rescue, of course! That is what this post was supposed to be about all along...so long ago...anyway! Let's get those names in order. Since it is unlikely we would need this random order again in the future, we will go ahead and use #map!
to actually alter the original hash.
> my_hash.map {|k,v| [k, v.sort]}.to_h
=> {"Group 1"=>["Ben", "Erick", "Erin", "Max", "Stacie"],
"Group 2"=>["Andrew", "Brenda", "Daniel", "Harmin", "Philip"]}
Magic! Well, almost. I threw that last little #to_h
in there so that you could see the resuls more closely in appearance to the original hash. Without that, the result would have been in a two-dimensional array because #map
always returns an array when given a code block.
Phew! I figure it's about time to wrap this up. Hopefully it has been at least somewhat beneficial to you either by increasing your understanding of #map
or at the very least let you see what can happen when I start a blog post too late after a full week of work. If I managed to just confuse you more than you were before, feel free to contact me via any of the nifty buttons on my main page.

This keyboard class driver is compliant with Plug and Play on Windows® 2000 and beyond. The behavior of the various routines is documented in the source code files. The driver works on both 32 and 64 bit platforms.
In addition to Plug and Play, the driver supports legacy Windows NT® 4.0-style input devices, Power Management, and all other Windows 2000 drivers.
The files necessary to build the sample include Kbdclass.c, Kbdlass.h, Kbdlass.rc, Kbdlog.rc, the makefile, and the sources. Once built, the sample produces a keyboard class driver (Kbdclass.sys). One binary is produced. Both checked and free build are available and functional. KEYBOARD.INF (the inf required to load this driver) is a system INF.
This sample is the complete source code for the shipping keyboard
class driver, which runs always on Windows systems since Windows 2000.
It is therefore always installed. As a system binary, it is also
subject to Windows File Protection. For Windows XP and prior releases,
you can replace kbdclass.sys in the %Windir%\System32\Drivers directory to
use your customized version. As of Windows Vista, it is no
longer possible to overwrite system binaries on the filesystem, so
replacing the inbox version for debugging will require use of a kernel debugger and
the .kdfiles command. Alternatively, it is possible to rename the
binary and inf and install the driver as a separate instance; this
would not replace the inbox kbdclass, but would allow the modified
driver to load.

The biggest threat that Pakistan is facing is not its current political tribulations or its endemic terrorism; its the threat of losing a basic human necessity. The International Monetary Fund (IMF) has recently ranked Pakistan third among countries across the world that are facing severe water shortages. The unfortunate reality is that the population in Pakistan continues to rapidly grow, while the supply of fresh water is continuing to decline as fast. The Pakistan Council of Research in Water Resources warned the public that the country would run out of drinkable water by 2025. The country crossed the "water scarcity line" in 2005, resulting in worsening drought-like conditions for the Pakistani people.
In light of this unfortunate reality, Paani is an organization based in Ann Arbor, Michigan, USA that strives to create both short-term and long-term solutions to create sustainable change within the water crisis. Our current partnerships have allowed us to build wells in Pakistan with the help of non-profits like Baitulmaal and Hassan Foundation. We are currently working with engineers to continue to improve the design of these wells to increase the efficiency of water retrieval and increase its resistance to weather/natural disasters.
The versatility of water also affects life-changing institutions such as Mehran Charitable Hospital. Organizations like this provide free health check-ups for the vulnerable and poor who are not able to afford treatments in larger hospitals due to financial or distance barriers. We have had the opportunity to work with this health clinic to increase its efficiency and facilitate its switch to renewable energy to decrease costs and increase the number of patients that can be seen.
Recognizing our privilege in being raised in an area that is surrounded by 25% of the world's fresh water, we have been inspired to work on creating systemic change within Pakistan. Supporting the implementation of water systems in Pakistan has never been a political issue; it was and continues to be a humanitarian issue.

About me
I Geek out over Geography, make maps, crunch numbers/code on computers, and generally play around with stuff. Life is short so do what you love, and I love a lot of different things. So I thought I would build a website to show off some of the exploits my monkey brain comes up with from time to time. This is a constant work in progress.  None of it is exhaustive or meant to be a walk through, but if you have questions about any of it please reach out to me.
When I am not working on maps, or coding on computers I enjoy the outdoors. Hiking, backpacking, biking, surfing, fishing, etc. I also enjoy cooking and building DIY projects. I think all of these things are important to keep your brain well lubricated and balanced for complicated tasks like coding and developing.
What I love Doing

Geographic Information Sciences. Using geospatial information to empower decision making
Coding
The thrill of building custom applications (usually geospatial) is hard to beat
Data Geeking
Give me a good piece of data. Lets dig into it, have some fun and get some data viz going.
Outdoor play
Close the laptop and crank some peddles, hop on a surfboard, or strap on some skis. It does the mind and body well
Photography
Am I good at it? No. Do I do it often? No. Do I enjoy it. Yes.
Tinkering
From building campers, to remodeling a bathroom, to repairing bikes. If I can break it, I enjoy tinkering on it

The Caemlyn Road was not very different from the North Road through the Two Rivers. It was considerably wider, of course, and showed the wear of much more use, but it was still hard-packed dirt, lined on either side by trees that would not have been at all out of place in the Two Rivers, especially since only the evergreens carried a leaf.
The land itself was different, though, for by midday the road entered low hills. For two days the road ran through the hills—cut right through them, sometimes, if they were wide enough to have made the road go much out of its way and not so big as to have made digging through too difficult. As the angle of the sun shifted each day it became apparent that the road, for all it appeared straight to the eye, curved slowly southward as it ran east. Rand had daydreamed over Master al’Vere’s old map—half the boys in Emond’s Field had daydreamed over it—and as he remembered, the road curved around something called the Hills of Absher until it reached Whitebridge.
From time to time Lan had them dismount atop one of the hills, where he could get a good view of the road both ahead and behind, and the surrounding countryside as well. The Warder would study the view while the others stretched their legs, or sat under the trees and ate.
“I used to like cheese,” Egwene said on the third day after leaving Baerlon. She sat with her back to the bole of a tree, grimacing over a dinner that was once again the same as breakfast, as supper would be. “Not a chance of tea. Nice hot tea.” She pulled her cloak tighter and shifted around the tree in a vain effort to avoid the swirling wind.
“Flatwort tea and andilay root,” Nynaeve was saying to Moiraine, “are best for fatigue. They clear the head a


By default, an element size does not include the border or padding. With Border Box, the element padding and border is included in its size.
We can apply Border Box to all elements (and pseudo elements), by using this CSS:
*, *::before, *::after {
box-sizing: border-box;
}

Important Class Notes:
What is process.argv
“The process.argv property returns an array containing the command line arguments passed when the Node.js process was launched.”
You can use this to find out what arguments are being passed into your program, if a certain argument is supplied you can have the node.js program do something that it wouldn't do if there weren’t any supplied arguments.
With process.argv the first element will be node.js path. The second element is the path to the js file being executed. Every element after is a user supplied argument.
process.argv stores everything as an array, so to view a specific argument, use indexing as such: process.argv[2] - would return the first ‘user supplied’ argument. process.argv[0] - returns the PATH to node.js exec.


Microservices is a term used to describe two things:
One, cloud servers which provide access to a single resource in a distributed computational system.
Two, an overall trend of computing moving away from large, monolithic codebases towards smaller, reusable components.
Specific platforms and frameworks.
Distributed computing. Not modular approaches in a single system. eg. Linux.
Containers (Docker, Vagrant) are generally used in production environments, not discussing.

Problem: My application can't search Twitter via a client side GET. They want me to use an API.
Solution 1: Building an external API integration into the application, manage authentication, and handle API keys in the same codebase.
Solution 2: Microservice. 10 lines of server logic to search Twitter via a proxied GET call and forward the results.
Authentication is isolated, bad calls won't reach microservice, API keys are provided by the container at run time.
Problem: Client needs to compose results from Multiple Databases. User info is in Mongo, their transactional data is in SQL and the recommendation engine uses Neo4j.
Putting all this business logic into a single codebase is possible, but not easy to maintain or reason about. Long, intensive processes will lead to memory bottlenecks and server downtime.
Solution: Several Microservices, one for each database, connected via a Event-style messaging system to compose requests and return results.
REST / RPC - Send, Wait for Response
Two directional. External API, Database Access. Ordered Operations.
RabbitMQ, ZeroMQ, Redis - Pubsub, Message Queue
One directional. Data Transformations and Processing. Ordered queues for workers. Distributed data ingestion. Operations in Parallel.
Microservices can be either, and a comprehensive system will incorporate both types.
Sequential - Machine Code, BASIC, GOTO
Procedural - Functions, Headers, Abstraction
Abstraction - Classes, OOP, Encapsulation
Functional - LISP, Clojure, Composing, Immutability
Microservices are generally a variant of the Interface Pattern, used to provide access to an underlying service without exposing underlying logic which permits decoupling.
Coupling is a measure of how vulnerable to change the connection between two software entities are. A "loosely coupled" connection maintains only the bare minimum of connection required to function, and thus, requires less cognitive effort to maintain.
Traditionally, OOP classes incur a wide range of coupling costs, which usually increase as changes are made to the system.
Microservices encourages better software architecture, the edge between services forces a simple interface which can be easily documented and built upon.
Consider a typical CRUD Over REST. Create Read Update Delete
In almost every application, Read will be used 99% of the time. Heavy use incurs a performance cost to clients who Create and Update.
A Microservice approach would make an stand-alone Read service and scale that indepedently of the other, less requested database operations.
Logging - Lots of servers means it's more difficult to debug without intentional visibility.
Edge Documentation - For developers to be functional in a microservices architecture, function, context, inputs and outputs must be clearly defined.
Choice of Tools / Cloud Provider - Flexibility in choosing the right tool for the task. Not for cloud beginners.
Tests - Without automated testing, your microservices will fail and burn.
Local Development - Using containers, a developer should be able to reproduce the environment locally.
Health Check - At a minimum, microservices should include a health check endpoint for monitoring. Each cloud service has it's own approach.
Thanks for listening.

Using TensorBoard to Observe Training
ML-Agents saves statistics during learning session that you can view with a TensorFlow utility named, TensorBoard.
The learn.py
program saves training statistics to a folder named summaries
, organized by the run-id
value you assign to a training session.
In order to observe the training process, either during training or afterward, start TensorBoard:
- Open a terminal or console window:
- Navigate to the ml-agents/python folder.
From the command line run :
tensorboard --logdir=summaries
Open a browser window and navigate to localhost:6006.
Note: If you don't assign a run-id
identifier, learn.py
uses the default string, "ppo". All the statistics will be saved to the same sub-folder and displayed as one session in TensorBoard. After a few runs, the displays can become difficult to interpret in this situation. You can delete the folders under the summaries
directory to clear out old statistics.
On the left side of the TensorBoard window, you can select which of the training runs you want to display. You can select multiple run-ids to compare statistics. The TensorBoard window also provides options for how to display and smooth graphs.
When you run the training program, learn.py
, you can use the --save-freq
option to specify how frequently to save the statistics.
ML-Agents training statistics
The ML-agents training program saves the following statistics:
Lesson - Plots the progress from lesson to lesson. Only interesting when performing curriculum training.
Cumulative Reward - The mean cumulative episode reward over all agents. Should increase during a successful training session.
Entropy - How random the decisions of the model are. Should slowly decrease during a successful training process. If it decreases too quickly, the
beta
hyperparameter should be increased.Episode Length - The mean length of each episode in the environment for all agents.
Learning Rate - How large a step the training algorithm takes as it searches for the optimal policy. Should decrease over time.
Policy Loss - The mean loss of the policy function update. Correlates to how much the policy (process for deciding actions) is changing. The magnitude of this should decrease during a successful training session.
Value Estimate - The mean value estimate for all states visited by the agent. Should increase during a successful training session.
Value Loss - The mean loss of the value function update. Correlates to how well the model is able to predict the value of each state. This should decrease during a successful training session.

A deliciously easy and luxurious pudding for dinner parties and gatherings.
Equipment: you will need 4 small pudding basins (dariole moulds)
Preheat the oven to 180C/160C Fan/Gas 4.
Butter 4 small pudding basins (dariole moulds) and dust with flour, shaking out any excess and place them on a baking tray.
To make the pudding, pour 200ml/7fl oz boiling water over the dates in a medium bowl. Add the vanilla seeds and bicarbonate of soda, mix to combine and leave to soak.
In a clean bowl, cream the butter with the sugars using an electric whisk. Beat in the egg a little at a time then gently fold in the flour and spices. Pour in the date mixture and stir well.
Divide the mixture equally between the prepared basins, they should be roughly two-thirds full. Cook for 15-20 minutes or until well-risen and springy to the touch. Allow to cool and then remove from the moulds.
To make the sauce, combine all ingredients in a large saucepan and place over a low heat until the sugar has dissolved.
To serve, pour a small amount of sauce over each pudding (as desired) and finish with chopped walnuts.


Lauryn Hill unveils 'Guarding the Gates,' a song from the film 'Queen & Slim'
LOS ANGELES, Nov 16 — The grande dame of R&B is back with a new title on the soundtrack for Queen & Slim, which has just been released.
Lauryn Hill has yet to make up her mind to release a follow-up to The Miseducation of Lauryn Hill which topped the charts two decades ago, however, fans of the neo-soul and R&B album will be pleased with this latest track from Queen & Slim by Melina Matsoukas.
Blood Orange, Bilal, Mike Jones, Roy Ayers, and many others feature along with Hill on the soundtrack that also includes a track by Tiana Major9 and EarthGang, Collide, which dropped in October.
Queen & Slim, directed by Melina Matsoukas (Master of None, Insecure), tells the tale of a couple played by Daniel Kaluuya (Get Out) and Jodie Turner-Smith (The Neon Demon), who are forced to go on the run when Kaluuya's character kills a police officer (played by Sturgill Simpson) in self-defence.
Indya Moore, Chloe Sevigny and Flea also feature in the cast for the film, which is due for release on November 27. — AFP-Relaxnews


About Me
Who Am I?
Hi! My name is Brian Wu, and I am a freshman at Stanford University majoring in Engineering Physics on the Computational Sciences Track. For the past three years, I conducted extensive self-directed research in planetary science, utilizing the Doppler spectroscopy technique to discover new exoplanets as well as developing software and Artificial Intelligence solutions that provide a more precise and efficient method to detect these exoplanets. My research primarily focused on a Tatooine-like circumbinary planet (a planet orbiting two stars), the first of its kind to be identified using Doppler spectroscopy.
I'm currently serving as Co-Founder and CEO of Vitol, a drone delivery company specializing in medical and humanitarian relief efforts. The Coronavirus pandemic not only demonstrated the inequities we as a society face in healthcare, but also the need for a more efficient transportation solution that minimizes human contact. Vitol seeks to accomplish exactly that - the future of transportation lies in the aerial realm, so let's build roads in the sky, together.
I'm highly skilled in data analytics and Machine Learning using MATLAB, Python, and IDL (Interactive Data Language). Additionally, I am also proficient in a wide variety of 3D Modeling techniques (primarily utilizing SolidWorks, AutoCAD/Inventor/Fusion 360, and Blender) as well as Computational Fluid Dynamics (CFD), having built the flight systems analysis and airfoil flow model simulation software for Vitol's first prototype drone.
Aside from engineering and piloting delivery drones, running a startup, as well as college classes, I love to spend my time as active as I can be! Whether it's skiing, squash, basketball, road running, or bodybuilding, there's always something fun to do as long as you're active. I spend a lot of my free time experimenting with music production, and am currently working towards releasing select covers and original works on SoundCloud. Recently, I've been getting super into stock trading via RobinHood, so feel free to reach out if you'd like to have a virtual coffee chat about our common interests!
I'm always on the lookout for new challenges and opportunities for personal growth, as well as applying my talents in Engineering, Software Development, Research, and Entrepreneurship to world-changing causes. If you think I'd be a great fit for your mission, I'm more than happy to chat at brian.wu@stanford.edu!

Cop Land (1997)
Seen on 20 September 1997 at the Cineplex Baronet Coronet for free.
What has an ensemble cast, pointless flashbacks, a love of policemen, 90 minutes to bore an audience to death, has only two funny moments, one overblown dramatic moment, and stinks? No, it's not Mayor Giuliani's campaign. It's Cop Land. A lot of people were leaving the theatre within the first half hour. Of course, it was free to anyone who was there for the preview. I would have left, but I rarely leave a theatre, and besides, I had to see if this would be the worst movie I have seen since Excess Baggage.
Cop Land would probably read better than it films. The high-concept premise here is that Garrison, NJ (not it's real name) is a town of 1280 people, mostly police (all of whom are white) and their families and embroiled in a deep cover up. Already, the prospect of watching corrupt straight white men is unappealing; I could just watch the news every night and review that.
Sheriff Freddy Heflin (Sylvester Stallone) is the "law" in Garrison, and he has a childlike trust in those who have empowered him to guard the American Dream. The worst thing that happens to him is bumping his nose on the steering wheel while swerving to miss a deer caught in his headlights. But the American Dream, in this case, is built an a lie. Oooooo. How shocking. Corrupt cops (Harvey Keitel, Ray Liotta, Peter Berg, etc.) work in New York City, which they hate, and come home to be above the law to a town across the George Washington Bridge, which, oh so ironically, overlooks New York.
 Lots of subplots and "buddy boy" nonsense ensues. The film takes its sweet time and when Freddy finally figures out he is living in a gangster movie, it is too late to care. That he is deaf in one ear, the result of saving the love of his teen years, who married some other putz, keeps him off the NYPD he reveres, and out of our sympathies.
Ultimately, Cop Land is something that would have been a great book, but is in fact, a dreadful movie. There are simply too many characters and subplots to keep track of or care about. I watch soap operas and read 19th Century Russian novels, but this was too much of a challenge. There are so many other ways to watch stories like these, and one springs to mind. NYPD Blue. Tuesday nights on ABC, 10 Eastern, 9 Central. Slow and steady builds audience interest. Throwing dressed up pigs (no pun intended) in the form of an All-Star cast into this mishmash was a real waste. The only actor missing from this mix was Steve Buscemi.
One of Three Woman Shown in the Cast: Cathy Moriarity, who is often seen holding a drink or looking like she ought to be.
Most Annoyed Actor with a Bad Haircut: Robert De Niro as the very exasperated Internal Affairs officer with a very very very bad haircut.
Smartest Actor: Janeane Garofolo, as the Sheriff's Deputy who does the only logical thing in the movie; she leaves town.
Best Ironic Line: Ray Liotta tells Stallone that there are two kinds of people in this world: Video game players and pinball players. I guess those were the intended audience members.

We choose to go to the moon in this decade and do the other things, not because they are easy.
Because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone and one.


It was just another boring day at summer school. It was a Friday, I had no plans for the weekend and my girl friend had been on vacation for the past 2 weeks and wouldn't be getting back for another 3 days. I had my usual ritalin in the morning, to wake me up.
Just as I got home I received a call from my speedhead friend (we hunt, share, and do speed together daily). He asked me right away if I had any plans, and if I didn't, then did I have any money and how much? I said yes, about twenty bucks, why? He then told me a girl we know who is a meth head is selling a half gram of some really good coke for 30 bucks. I was at his house in 3.. 2.. 1...
Neither of us had ever gotten to doing coke, I had some experience with the substance from doing ecstacy which contained MDMA, meth, and coke. But never just plain cocaine, which had always surprised people since I am such a speedhead. Wasting no time we ran up to his room and chopped/lined it up. I had paid more, so I went first. I hadn't felt any real need to every try it, I was always more interested in e and meth, but the way people talked about it made me give it a shot.
On the initial pull there was no real rush at all. I snort so much speed that I barely ever feel a rush anymore. I passed the box with the rest of the lines in it to my friend and proceeded to licking the plastic it had come in. I did not see what the big deal was, the taste wasn't good, but it wasn't bad. It did not burn much, I felt barely anything at all.
When it began to hit me I was loving it. I got the floaty feeling I get from a lot of ritalin, but also an overwhelming feeling of freedom, confidence, and belonging. This combined with my new rush of energy and numbness had me suggesting we go for a walk right away. Time just flashed by, I remember us having some extremely strange conversations.
Towards the end of the night my friend stopped by and we did the last two bumps that were left, then we sat in my room listening to music while I played guitar. We would just keep looking at each other and smiling, without saying a word. If one of us started speaking the other one wouldn't really be comprehending what was being said, but neither cared. Somehow it just felt that we were on the same level, and understood each other perfectly.
After he left the fun ended. I began to shake, I was nervous beyond belief. I felt more paranoid than any amount of speed has ever made me. I felt so alone, but when I would talk to people I would just zone out. I could hear what was being said but I didn't care, I didn't care to even try. Deciding that since it was now about one in the morning and there wouldn't be any chance of sleep for the next few hours I called my girl friend. This was bad. I really wanted to talk to her, I really missed her, it felt like there was a never ending list of things that I wanted to tell her, but just couldn't. I told her of what I'd done over the course of the day and she was worried. This did not make me feel any better. It seemed like I was numb to all the positive emotions of life, and all the negative ones would be amplified. I told her I was going to go to sleep. It took me five hours in bed until I woke up at seven.
I woke up with much the same feeling, maybe not as bad. I smoked weed a few times in the morning to make myself feel a bit better and to help me come down. I didn't come down until about three pm.
Overall the high was great, the experience was fun. But the coming down is too much, this added to the price would make me say that it's really not worth it, I'm happier with high dosage's of ritalin. I might try it again some time, but I definately don't see how this could be so addicting to some.

Both interfaces provide traverse the collection and fetch objects from it.
But, there are 2 differences between Iterator and Enumeration interface.
public interface Iterator {
public boolean hasNext();
public Object next();
public void remove();
}
Enumeration interface doesnt have this method. Enumeration acts as Read-Only interface.
public interface Enumeration {
public boolean hasMoreElements();
public Object nextElement();
}
Iterator doesnt allow multiple threads modify the collection at the same time. Therefore, ConcurrentModificationException is not thrown while traversing the collection through the use of Iterator interface. Whereas Enumeration interface cannot provide this feature. Enumeration is not thread-safe interface.

Caleb Ekuban to convince Daniel Amartey to join him at Trabzonspor
Defender Daniel Amartey could join Turkish side Trabzonspor in the winter transfer window.
According to Turkish news outlet, Fanatik, the Leicester City fringe player is being persuaded by international teammate Caleb Ekuban to join him in Turkey.
Amartey is yet to make an appearance for the Foxes this season, after making a return from a long injury lay off.
The 24-year old has lost his position to Ricardo Pareira, and has to work hard to find his way back in the team that has conceded the fewest goals in the English Premier League.
Meanwhile, Caleb Ekuban has been enjoying a good spell in Turkey since moving to Trabzonspor last season.
He had a good start to the campaign, where he scored 5 goals in seven games before getting injured but he could return in the game against Galatasaray.
Ekuban made 20 league appearances for the Elland Road club between 2017 and 2019, turning out for his nation on four occasions along the way.
Amartey has 222 caps for Ghana despite missing the 2019 nations cup due to injury.

--- title: Bert for Multi-task Learning keywords: fastai sidebar: home_sidebar nb_path: "source_nbs/index.ipynb" ---
Note: Since 0.4.0, tf version >= 2.1 is required.
pip install bert-multitask-learning
This a project that uses transformers(based on huggingface transformers) to do multi-modal multi-task learning.
In the original BERT code, neither multi-task learning or multiple GPU training is possible. Plus, the original purpose of this project is NER which dose not have a working script in the original BERT code.
To sum up, compared to the original bert repo, this repo has the following features:
There are two types of chaining operations can be used to chain problems.
&
. If two problems have the same inputs, they can be chained using &
. Problems chained by &
will be trained at the same time.|
. If two problems don't have the same inputs, they need to be chained using |
. Problems chained by |
will be sampled to train at every instance.For example, cws|NER|weibo_ner&weibo_cws
, one problem will be sampled at each turn, say weibo_ner&weibo_cws
, then weibo_ner
and weibo_cws
will trained for this turn together. Therefore, in a particular batch, some tasks might not be sampled, and their loss could be 0 in this batch.
Please see the examples in notebooks for more details about training, evaluation and export models.
注意：版本0.4.0后要求tf>=2.1
pip install bert-multitask-learning
这是利用transformer(基于huggingface transformers)进行多模态多任务学习的项目.
在原始的BERT代码中, 是没有办法直接用多GPU进行多任务学习的. 另外, BERT并没有给出序列标注和Seq2seq的训练代码.
因此, 和原来的BERT相比, 这个项目具有以下特点:
可以用两种方法来将多个任务连接起来.
&
. 如果两个任务有相同的输入, 不同标签的话, 那么他们可以用&
来连接. 被&
连接起来的任务会被同时训练.|
. 如果两个任务为不同的输入, 那么他们必须用|
来连接. 被|
连接起来的任务会被随机抽取来训练.例如, 我们定义任务cws|NER|weibo_ner&weibo_cws
, 那么在生成每一条数据时, 一个任务块会被随机抽取出来, 例如在这一次抽样中, weibo_ner&weibo_cws
被选中. 那么这次weibo_ner
和weibo_cws
会被同时训练. 因此, 在一个batch中, 有可能某些任务没有被抽中, loss为0.

The New Survivalist

Chapter 7:
|
| |
Survival ShelterHopefully you will never be forced to leave your home. Your chances of survival will be much greater if you can remain in the safety of your own private shelter. But if for some reason you are ever forced to leave your home you will need to take as many supplies as you can reasonably carry. If the weather is cold you will need plenty of warm clothing in your bug out bag. You may also want to take a lightweight tent and sleeping bags. If you can avoid seeking refuge in a government-run shelter you will probably be better off. |
| Even if you are not forced to leave your home you will need to prepare for power outages. You can start now by making your home more energy efficient. Locate areas where your house loses energy and correct them. Consider how comfortable your home will be during hot weather when you are without air conditioning. Perhaps you can improve your landscapingplanting trees to provide shade during the hot months and protection from frigid winds during the cold months. |
| Consider how you can close off portions of your home during an emergency to save on energy usage. If you are reduced to heating with kerosene, a wood-burning stove or a propane camping stove, it will be much more practical to heat just one or two rooms of your house, rather than trying to keep the whole house warm. Trying to heat rooms which are not in use will result in an unnecessary loss of crucial energy supplies. |
|
If your family enjoys camping, you probably already own a lot of the survival equipment that you will need, including portable propane stoves, lanterns and heaters. If you are not a camper, I certainly recommend that you consider the hobby. At least once a year take a camping trip to a nice natural location, such as a state park. But don't go with the intention of hooking up to the campsite's electrical, water and sewage systems. Leave your television at home! Primitive camping will teach you many survival skills. Learn how to build a campfire (using only matches, newspapers and twigs to start it.) Learn to cook on your campfire, as well as on your portable propane camping stove. Stay in a tentnot in an air-conditioned trailer or RV! Learn what it is like to have to carry your water from the source to your campsite, and how to wash your dishes, with water heated on your stove or campfire, without the convenience of an automatic dishwasher. Camping is a lot of fun! Part of that fun comes from the adventure of living temporarily in more primitive conditions. The lessons you will learn will be priceless! Do it regularly. You will learn what you really need to get by in times of emergency, and eventually you will accumulate everything that you will need to be more self-sufficient in an emergency. |
|
Camping regularly will also help you keep your emergency equipment in topnotch condition. When a disaster strikes, not only will you have many of the items that you will need to make your life easier, you will also be experienced in how to use them under primitive conditions. But even more importantly, you and your family will have the confidence that comes with knowing how to get by "off the grid." |
|
Action Step 13: Shelter Check ListsTurn to the page in you Action Planner where you have begun your "Get" and "Do" lists for shelter and begin making your lists. On your "Do" list include home improvements to make your house more energy efficient. The camping check list below will help you with your "Get" list. This is the check list that we use every time we make a camping trip, to insure that we don't forget something. Camping Check List:
Shelter
|
Building a CampfireYou should be able to light a campfire with only one or two matches without using lighter fluid or gasoline. They key is proper planning and preparation, using the materials that are easier to ignite to start the materials that are more difficult to ignite. First, select a suitable location where there is little danger of creating a wildfire. Avoid starting a fire when conditions are very dry and windy. Begin by collecting the materials that you will need to start your fire. Place newspapers, dead leaves, or other easily-ignitable dry material on the bottom. If you are using newspaper it must be crumpled so that air can easily get to it. On top of the newspaper place dry twigs and small sticks. Then place larger sticks on top of the smaller sticks, leaving plenty of spaces for air. This is easily accomplished by placing the larger sticks in a teepee formation over the newspaper and smaller sticks (as in the photograph below.) Use one match, or hold two matches together, and light the newspaper first. The newspaper will ignite the twigs, which will ignite the smaller sticks, which will ignite the larger ones. |
|
Once the larger sticks are burning well you can add larger and larger pieces, until your fire is finally ready for the largest long-burning logs. |
|
A fire place poker is helpful for moving the logs around to improve the flow of air and keep the fire going strongly. |

cma.fitness_transformations.EvalParallel(object)
class documentationcma.fitness_transformations
(View In Hierarchy)
A class and context manager for parallel evaluations.
To be used with the with
statement (otherwise terminate
needs to
be called to free resources):
with EvalParallel() as eval_all: fvals = eval_all(fitness, solutions)
assigns a callable EvalParallel
class instance to eval_all.
The instance can be called with a list
(or tuple
or any
sequence) of solutions and returns their fitness values. That is:
eval_all(fitness, solutions) == [fitness(x) for x in solutions]
EvalParallel.__call__
may take two additional optional arguments,
namely args
passed to fitness and timeout
passed to the
multiprocessing.pool.ApplyResult.get
method which raises
multiprocessing.TimeoutError
in case.
Examples:
>>> import cma >>> from cma.fitness_transformations import EvalParallel >>> # class usage, don't forget to call terminate >>> ep = EvalParallel() >>> ep(cma.fitness_functions.elli, [[1,2], [3,4], [4, 5]]) # doctest:+ELLIPSIS [4000000.944... >>> ep.terminate() ... >>> # use with `with` statement (context manager) >>> es = cma.CMAEvolutionStrategy(3 * [1], 1, dict(verbose=-9)) >>> with EvalParallel(12) as eval_all: ... while not es.stop(): ... X = es.ask() ... es.tell(X, eval_all(cma.fitness_functions.elli, X)) >>> assert es.result[1] < 1e-13 and es.result[2] < 1500
Parameters: the EvalParallel
constructor takes the number of
processes as optional input argument, which is by default
multiprocessing.cpu_count().
Limitations: The multiprocessing
module (on which this class is
based upon) does not work with class instance method calls.
In some cases the execution may be considerably slowed down, as for example with test suites from coco/bbob.

It is common in audio (and other kinds of signal processing) to
convert a time-domain signal to a spectrogram via the short-time Fourier transform (STFT)
modify the spectrogram to get
convert the modified spectrogram back to a time-domain signal via the inverse short-time Fourier transform (ISTFT)
An example of such processing is spectral subtraction for noise reduction.
When creating the spectrogram in Step 1, a window is usually applied to the samples in each frame, and the frames overlap. Because of this, it is not completely obvious if and how it is possible to construct a time domain signal from the modified spectrogram.
In fact, depending on the processing that is done, there may not be a time-domain signal whose STFT is exactly the output from Step 2. In this note, we are going to ignore this issue and consider only the simple case where we don’t do anything in Step 2: . That is, we want to recover the original signal and understand under what conditions it is possible to do so. The good news in this case is that, given conditions that are easily achieved in practice, it is possible to invert the STFT and exactly reproduce .
It is less common, but sometimes done, to carry out similar processing in the time domain. The steps are
convert a time-domain signal to a series of overlapping, windowed frames
modify the frames to get
convert the modified frames back to a time-domain signal
An example of such processing is to remove segments of an audio signal whose energy is below a threshold and are regarded as silent.
Again, we will focus on the case where no modification is done and ask when is it possible to recover from the It is expected that if we can do that, similar techniques will be valuable for the case where modifications are done.
The first condition for invertibility is that there is no gap between the frames. This makes intuitive sense because otherwise we are leaving out some samples when doing the windowing, so there is no way to reconstruct them.
The second condition is related to the specific technique used, which is called overlap-add and is explained below. It is common in the literature to find mention of the constant overlap-add (COLA) constraint. As we will see, this is a sufficient condition to achieve invertibility, but it is stronger than necessary and somewhat difficult to satisfy. We will show that the necessary condition, nonzero overlap-add (NOLA) constraint, is much weaker and is easily achieved.
Recent versions of SciPy include functions for the STFT and ISTFT. This note was prompted by the implementation of the istft function in scipy.signal (v1.0.0) which will check if COLA is satisfied and will abort if not. We want to make the case for removing that check.
There are lots of equations in what follows, but the mathematics is elementary and we have taken pains to be clear, perhaps to the point of being pedantic. A short Python script which illustrates the points made in this note is available here.
Let’s suppose we have a sequence of length that we want to analyse in successive frames of length with a hop size of from one frame to the next. We will only consider the case where there are no gaps between frames, which means that In other words, successive frames overlap by samples.
We’ll use (for time) as the index of the frames and as the index of the frequencies in a given frame. The samples in frame are
Let be a window function So far we have regarded and as finite sequences of length and respectively. To simplify the notation in the following, we will assume that they have both been extended to be defined for all by zero padding. The samples in the windowed frame can then be conveniently described as
Again, is defined for all but only a finite number of samples are nonzero.
We start with the easier case, which is time-domain processing.
We will arrive at the overlap-add technique by starting with the following sum. Note that we use infinite limits in the following, but only a finite number of terms are non-zero. For any (unless some of the , in which case we must have consider
We can then recover from
as long as the denominator is not zero. We call this the nonzero overlap-add (NOLA) constraint
A stronger constraint is constant overlap-add (COLA), defined by
for some constant An even more restrictive condition is that
If and the window satisfies the strong COLA constraint then we have a particularly simple inversion formula
However, while the COLA constraint is sufficient, it is not necessary for exact invertibility to be possible.
Although COLA is often introduced for the value the most common choice is for reasons that we will explain below.
where all sequences are extended to by zero padding.
The Fourier transform of frame is
We define a sequence which is the inverse Fourier transform of in frame and zero-padded for other
Because we did not modify we have But we’ll keep the notation to look forward to the situation where we do have a modified
By analogy with overlap-add in the time domain we consider the following sum. The equations look horrendous, but the calculation is straightforward.
In the line marked (*), we used Lemma 1 (below). In the next line, we used the fact that and are nonzero for the same values of
We conclude that
which is valid when the denominator is not zero. The inversion formula is valid under any of the following conditions, listed in order of increasing strictness
NOLA: for all
for all (see Lemma 3 below)
COLA: for all and some constant
Strong COLA: for all
As mentioned above, it is most common to choose The reason is that in the case where we did modify the STFT, there may not be a time-domain signal whose STFT matches our modified version. Choosing gives the Griffin-Lim optimal estimate (optimal in a least-squares sense) for a time-domain signal from a modified STFT. SciPy implements for the signal reconstruction in the istft routine.
We have shown that the commonly-used COLA constraint is sufficient but not necessary for the windowed time domain or STFT to be invertible. The weaker NOLA condition is necessary and sufficient. Almost all commonly-used window/overlap combinations satisfy NOLA.
We were motivated do this by the implementation of the SciPy library function istft. We recommend that the COLA constraint imposed by that function should be removed or at least made optional. Update: There is now a pull request for this in the SciPy repo.
Appendix
Lemma 1:
where
Proof: Using the formula for the sum of a geometric series, we have for the case
The case is obvious because in this case each term in the sum is equal to . QED
Lemma 2 (inverse Fourier transform):
Given a sequence its sampled discrete Fourier transform is
We can recover from by the equation
Proof: Substitute equation (3) into the right-hand side of equation (4) and use Lemma 1:
QED
Lemma 3:
Let be a window with strictly positive values: for all Extend to infinity at both ends by padding with zeros. Then if
for any
Proof: Since for we just need to show that for some
We’ll pick a that works. Let
By definition of the floor function,
Flipping this around and using the fact that , we have


About Me
I am studying informatics at the Ionian University. I am aspiring to learn as much as possible about what Computations are, the Processing of Information, and to become an expert Programmer. All in all i strive so that at the time this experience is over, i will know deeply about information theory, networks and every other interesting aspect of computers.
Experience
Oblix is a sophisticated restaurant with an incredible view as it is housed in The Shard, the tallest building in London.
As a commis waiter i had the responsibility of serving food to the tables, cleaning and setting them up, taking care of the tables and making sure everyone had a pleasant time. Other responsibilities included taking orders, serving drinks and assisting as needed on the floor.

Corfu
I am studying Informatics to aquire a B.S. degree and learn all the core concepts about how Databases, Operating Systems, Computer Networks and Computer Programming works. We are also being taught about the importance of Teamwork, working with tight Deadlines and Managing Projects.
The course also tought me about how computer graphics work, what is and how to use information retrieval techniques, machine learning and pattern recognition and lastly about virtual worlds and entertainment software.
Languages
Greek
Native Fluency
I was born in Greece and have lived here for the biggest part of my life so it is only natural that i speak Greek fluently.
