Overview¶
Concepts¶
WebAssembly encodes a low-level, assembly-like programming language. This language is structured around the following concepts.
- Values
- WebAssembly provides only four basic value types. These are integers and IEEE 754-2008 numbers, each in 32 and 64 bit width. 32 bit integers also serve as Booleans and as memory addresses. The usual operations on these types are available, including the full matrix of conversions between them. There is no distinction between signed and unsigned integer types. Instead, integers are interpreted by respective operations as either unsigned or signed in two’s complement representation.
- Instructions
- The computational model of WebAssembly is based on a stack machine. Code consists of sequences of instructions that are executed in order. Instructions manipulate values on an implicit operand stack [1] and fall into two main categories. Simple instructions perform basic operations on data. They pop arguments from the operand stack and push results back to it. Control instructions alter control flow. Control flow is structured, meaning it is expressed with well-nested constructs such as blocks, loops, and conditionals. Branches can only target such constructs.
- Traps
- Under some conditions, certain instructions may produce a trap, which immediately aborts execution. Traps cannot be handled by WebAssembly code, but are reported to the outside environment, where they typically can be caught.
- Functions
- Code is organized into separate functions. Each function takes a sequence of values as parameters and returns a sequence of values as results. [2] Functions can call each other, including recursively, resulting in an implicit call stack that cannot be accessed directly. Functions may also declare mutable local variables that are usable as virtual registers.
- Tables
- A table is an array of opaque values of a particular element type. It allows programs to select such values indirectly through a dynamic index operand. Currently, the only available element type is an untyped function reference. Thereby, a program can call functions indirectly through a dynamic index into a table. For example, this allows emulating function pointers by way of table indices.
- Linear Memory
- A linear memory is a contiguous, mutable array of raw bytes. Such a memory is created with an initial size but can be grown dynamically. A program can load and store values from/to a linear memory at any byte address (including unaligned). Integer loads and stores can specify a storage size which is smaller than the size of the respective value type. A trap occurs if an access is not within the bounds of the current memory size.
- Modules
- A WebAssembly binary takes the form of a module that contains definitions for functions, tables, and linear memories, as well as mutable or immutable global variables. Definitions can also be imported, specifying a module/name pair and a suitable type. Each definition can optionally be exported under one or more names. In addition to definitions, modules can define initialization data for their memories or tables that takes the form of segments copied to given offsets. They can also define a start function that is automatically executed.
- Embedder
- A WebAssembly implementation will typically be embedded into a host environment. This environment defines how loading of modules is initiated, how imports are provided (including host-side definitions), and how exports can be accessed. However, the details of any particular embedding are beyond the scope of this specification, and will instead be provided by complementary, environment-specific API definitions.
| [1] | In practice, implementations need not maintain an actual operand stack. Instead, the stack can be viewed as a set of anonymous registers that are implicitly referenced by instructions. The type system ensures that the stack height, and thus any referenced register, is always known statically. |
| [2] | In the current version of WebAssembly, there may be at most one result value. |
Semantic Phases¶
Conceptually, the semantics of WebAssembly is divided into three phases. For each part of the language, the specification specifies each of them.
- Decoding
- WebAssembly modules are distributed in a binary format. Decoding processes that format and converts it into an internal representation of a module. In this specification, this representation is modelled by abstract syntax, but a real implementation could compile directly to machine code instead.
- Validation
- A decoded module has to be valid. Validation checks a number of well-formedness conditions to guarantee that the module is meaningful and safe. In particular, it performs type checking of functions and the instruction sequences in their bodies, ensuring for example that the operand stack is used consistently.
- Execution
Finally, a valid module can be executed. Execution can be further divided into two phases:
Instantiation. A module instance is the dynamic representation of a module, complete with its own state and execution stack. Instantiation executes the module body itself, given definitions for all its imports. It initializes globals, memories and tables and invokes the module’s start function if defined. It returns the instances of the module’s exports.
Invocation. Once instantiated, further WebAssembly computations can be initiated by invoking an exported function on a module instance. Given the required arguments, that executes the respective function and returns its results.
Instantiation and invocation are operations within the embedding environment.

Sample function code
To process events from Amazon Kinesis, iterate through the records included in the event object and decode the Base64-encoded data included in each.
The code on this page does not support aggregated records. You can
disable aggregation in the Kinesis Producer Library configuration, or use the Kinesis Record
Aggregation library
Sample code is available for the following languages.
Topics
Node.js 12.x
The following example code receives a Kinesis event input and processes the messages that it contains. For illustration, the code writes some of the incoming event data to CloudWatch Logs.
Example index.js
console.log('Loading function'); exports.handler = function(event, context) { //console.log(JSON.stringify(event, null, 2)); event.Records.forEach(function(record) { // Kinesis data is base64 encoded so decode here var payload = Buffer.from(record.kinesis.data, 'base64').toString('ascii'); console.log('Decoded payload:', payload); }); };
Zip up the sample code to create a deployment package. For instructions, see Deploy Node.js Lambda functions with .zip file archives.
Java 11
The following is example Java code that receives Kinesis event record data as input and processes it. For illustration, the code writes some of the incoming event data to CloudWatch Logs.
In the code, recordHandler
is the handler. The handler uses the predefined
KinesisEvent
class that is defined in the aws-lambda-java-events
library.
Example ProcessKinesisEvents.java
package example; import com.amazonaws.services.lambda.runtime.Context; import com.amazonaws.services.lambda.runtime.RequestHandler; import com.amazonaws.services.lambda.runtime.events.KinesisEvent; import com.amazonaws.services.lambda.runtime.events.KinesisEvent.KinesisEventRecord; public class ProcessKinesisRecords implements RequestHandler<KinesisEvent, Void>{ @Override public Void handleRequest(KinesisEvent event, Context context) { for(KinesisEventRecord rec : event.getRecords()) { System.out.println(new String(rec.getKinesis().getData().array())); } return null; } }
If the handler returns normally without exceptions, Lambda considers the input batch of records as processed successfully and begins reading new records in the stream. If the handler throws an exception, Lambda considers the input batch of records as not processed and invokes the function with the same batch of records again.
Dependencies

aws-java-sdk
Build the code with the Lambda library dependencies to create a deployment package. For instructions, see Deploy Java Lambda functions with .zip or JAR file archives.
C#
The following is example C# code that receives Kinesis event record data as input and processes it. For illustration, the code writes some of the incoming event data to CloudWatch Logs.
In the code, HandleKinesisRecord
is the handler. The handler uses the predefined
KinesisEvent
class that is defined in the Amazon.Lambda.KinesisEvents
library.
Example ProcessingKinesisEvents.cs
using System; using System.IO; using System.Text; using Amazon.Lambda.Core; using Amazon.Lambda.KinesisEvents; namespace KinesisStreams { public class KinesisSample { [LambdaSerializer(typeof(JsonSerializer))] public void HandleKinesisRecord(KinesisEvent kinesisEvent) { Console.WriteLine($"Beginning to process {kinesisEvent.Records.Count} records..."); foreach (var record in kinesisEvent.Records) { Console.WriteLine($"Event ID: {record.EventId}"); Console.WriteLine($"Event Name: {record.EventName}"); string recordData = GetRecordContents(record.Kinesis); Console.WriteLine($"Record Data:"); Console.WriteLine(recordData); } Console.WriteLine("Stream processing complete."); } private string GetRecordContents(KinesisEvent.Record streamRecord) { using (var reader = new StreamReader(streamRecord.Data, Encoding.ASCII)) { return reader.ReadToEnd(); } } } }
Replace the Program.cs
in a .NET Core project with the above sample. For instructions, see Deploy C# Lambda functions with .zip file archives.
Python 3
The following is example Python code that receives Kinesis event record data as input and processes it. For illustration, the code writes to some of the incoming event data to CloudWatch Logs.
Example ProcessKinesisRecords.py
from __future__ import print_function #import json import base64 def lambda_handler(event, context): for record in event['Records']: #Kinesis data is base64 encoded so decode here payload=base64.b64decode(record["kinesis"]["data"]) print("Decoded payload: " + str(payload))
Zip up the sample code to create a deployment package. For instructions, see Deploy Python Lambda functions with .zip file archives.
Go
The following is example Go code that receives Kinesis event record data as input and processes it. For illustration, the code writes to some of the incoming event data to CloudWatch Logs.
Example ProcessKinesisRecords.go
import ( "strings" "github.com/aws/aws-lambda-go/events" ) func handler(ctx context.Context, kinesisEvent events.KinesisEvent) { for _, record := range kinesisEvent.Records { kinesisRecord := record.Kinesis dataBytes := kinesisRecord.Data dataText := string(dataBytes) fmt.Printf("%s Data = %s \n", record.EventName, dataText) } }
Build the executable with go build

clone_package.Rd
This function copies a data package from one DataONE Member Node to another. Note: the dateUploaded, obsoletes, and obsoletedBy fields in the sysmeta will be reset on the cloned object.

Juneau supports converting arbitrary POJOs to and from XML using ultra-efficient serializers and parsers.
The XML serializer converts POJOs directly to XML without the need for intermediate DOM objects.
Likewise, the XML parser uses a STaX parser and creates POJOs directly without intermediate DOM objects.
Unlike frameworks such as JAXB, Juneau does not require POJO classes to be annotated to produce and consume
XML.
However, several XML annotations are provided for handling namespaces and fine-tuning the format of the XML produced.
The following example shows XML for a typical bean:
| @Bean(typeName="person")
| public class Person {
|
| // Bean properties
| public String name;
| @Swap(TemporalCalendarSwap.IsoInstant.class) public Calendar birthDate;
| public List<Address> addresses;
|
| // Getters/setters omitted
| }
|
| @Bean(typeName="address")
| public class Address {
|
| // Bean properties
| public String street, city;
| public StateEnum state;
| public int zip;
| public boolean isCurrent;
|
| // Getters/setters omitted
| }
| Person person = new Person()
| .name("John Smith")
| .birthDate("1946-08-12T00:00:00Z")
| .addresses(
| new Address()
| .street("100 Main Street")
| .city("Anywhereville")
| .state(NY)
| .zip(12345)
| .isCurrent(true);
| );
| <person>
| <name>John Smith</name>
| <birthDate>1946-08-12T04:00:00Z</birthDate>
| <addresses>
| <address>
| <street>100 Main Street</street>
| <city>Anywhereville</city>
| <state>NY</state>
| <zip>12345</zip>
| <isCurrent>true</isCurrent>
| </address>
| </addresses>
| </person>
Juneau produces JSON-equivalent XML, meaning any valid JSON document can be losslessly converted into an XML
equivalent.
In fact, all of the Juneau serializers and parsers are built upon this JSON-equivalence.


Two summers ago, after forays into organic farming and yurt living, I found myself in a really cool position at the Ohio State University Agricultural Ecosystem Management Program that combined many things I was passionate about: building usable web systems, building community, and local agriculture. I was helping make changes to Local Food Systems, a website that helps connect entreprenuers with the food system (and those who run it) to help spawn new businesses based on the stream of goods and services in that system. I was working in Drupal, and helped guide user experience and user interface decisions and changes in the three months that I was there on a half-time contract.
When the end of August came, I was sad to find out that this awesome job could not become a full-time endeavor because there were no new grants for the project, and neither could my half-time contract be extended. That same week, I was contacted by an internal recruiter for Fathom, a digital marketing and analytics agency closer to where I had just moved, and began the conversation of becoming a full time web developer there.
Within a few weeks I was working for Fathom, building a lot of frontends to landing pages and microsites that were mostly used in email marketing and pay-per-click campaigns. In my first few weeks at Fathom, the Twitter-sphere was abuzz about gSchool, a 6 month web development program in Denver, Colorado. I checked out the website, read a little bit about it, and thought to myself, “Wow, it’d be so great to learn web development from the pros, but who has the time to spend 6 months not earning a paycheck?” I was intrigued by Ruby and thought it would be great to learn someday, but I moved on, back to my frontends, and back to my spaghetti PHP.
During my year at Fathom, I started getting more interested in Ruby, Test Driven Development, and Agile methodology, but the work we were doing on the web development team was rigid. But we sold our products well, and we had jam-packed development schedules. There was no time to explore or implement the things I was reading about, the things that I so desperately wanted to learn.
I thought I could fit in new learning by starting a Code for America Brigade in my town, dubbed Code for Summit County, and organizing an event for the National Day of Civic Hacking locally, called HackNEO, (which brought together over 30 local developers, designers, park lovers, and community memeber to hack on park data). As I worked and organized, I realized that if I was going to continue to be a leader, my learning needed a serious turbo boost to propel me forward past the bad habits I had acquired through self-teaching and a lack of a programming mentor.
I started exploring the option of attending one of those developer bootcamps that I had heard about. I needed a time and a place to focus on learning, without interruption. I researched all of them, read what students had to say about them, and thought about applying to them. But I wasn’t sure if I could do it. I had a life at home – three months (the average of these bootcamps) was a long time away from everything that needed my attention – family, chickens, my cat, my job…
And then it all boiled down to making a pros and cons list.
An honest, hard look at the opportunity cost, as well as the ways doing this now would pay off for the rest of my career, brought me to one conclusion: Just do it.
My focus was being close to home, in Chicago or New York at the bootcamps available there, when suddenly, seemingly out of the blue, Steve Klabnik tweeted an application deadline reminder for gSchool. I had been following Steve on Twitter for a while, but hadn’t realized he was an instructor for Jumpstart Lab, the company that runs gSchool. I took another hard look at gSchool, and completed the application. I didn’t think I stood a chance.
Fast-forward to today, and here I am, writing this post in Denver, Colorado. Next week we start gSchool[1], the second class that gSchool will graduate, and my coding adventures will continue. I will have experienced mentors helping me understand the tough spots, pushing me to the next level, and helping me unlearn bad habits, learn a new language, and build the skills needed to bring to life the ideas that have been gnawing at me for years.
I plan to document the journey so that others may have a map to guide them.

Our garden clearance service is for areas that need to be cleared for landscaping or other construction, for neglected or overgrown gardens.
We break up and remove patios, dismantle sheds, take apart concrete paths, demolish garden walks, etc. We also clear any kind of weeds, bushes, plants, trees, old turf or trunks and roots. We can clear areas quickly and efficiently, disposing of the green waste into licenced recycling centres.
The work is quicker if there is direct access to the garden. Otherwise the waste from the garden will need to be carried through the property. In these cases we cover your floor and protect walks and furniture. We will of course clean the area before the job is finished and keep disruption to a minimum.
Garden clearance waste can be bagged up and left on the site for council collection. Or we can take it straight for an additional charge. For waste disposal informations please see our price list below. With large volumes it could be necessary to hire a skip or a lorry. We arrange waste disposal, skip hire and road permit for you if required.
For smaller garden clearance projects we are able to discuss and quote the job on phone. We suggest to arrange a site meeting if the job takes longer than one or two days or need more worker than one or two.
We provide friendly, efficient regular garden maintenance to both residential and commercial customers, weekly, fortnightly and monthly or just one off tidy ups.
Garden clearence: we can help you to get your overgrown garden back in control. This service available at any time of the year either in stages or all at once, depending on your preferences.
Weed control: we can help you to keep patios, paths, beds, borders and pots clear of any weeds, moss, algies.
Planting: we supply plants for your requirements. Before planting we always make sure the ground well prepared, the soil enriched and improved using the appropriate method.
Pots and planters: we design seasonal displays or we can create and maintaine your balcony or terrace by following your instructions.
Pruning and hedge trimming: keeping plants healthy and strong. We prune fruit trees, roses, controll climbers and shape hedges and bushes.
Plant disase identification and controll: if you are not sure what is affecting your plants. We can help you to diagnose the problems. We will also provide both organic and chemical treatments as well as advice to help prevent problems in the future.
Watering: we can turn up regularly and water your pots on your balcony or water your lawn or plants. We can also design, supply and install your automatic watering system.
Jet washing & patio cleaning: we provide safe and professional jet washing for your driveway, patio and garden paths. In order to deliver the pressure washing service we will require access to a tap with decent water pressure, a power point and drainage in place for the water to flow away from the site.
Leaf clearing: it is an important job to clear away autumn leaves from your garden year to year.
Our landscaping team is specialist in ground work, turfing, block paving, driveways, patios, decking, pergolas, sheds, timber structures, fences, brick work, concreting, plant design and planting.
We offer a professional and reliable service with years of experience and expertise.
We provide a selection of samples and materials for our customers to choose from and offer advise every step of the way. We work with our customers to ensure their vision and end result is created.
Groundwork: whether it's levelling the garden, digging trenches, creating slope, steps or terraces our team can execute the work professionally. This is the work stage what usually prelude other work stages.
Professional planning, measuring and implementation of ground work is key factor in the success of later stages of landscaping. We practice the most suitable technique for every situation.
Paving: as a Marshalls Registered Company we take pride in our accreditation and the high standards met in order to become a Marshalls Registered company in 2016.
We want to supply high quality range of materials for our customers therefore we use all Marshall's Paving Products for all Block Paving, Driveways and Patios. For more choice we work with other paving and stone supplier companys such as St. Albans Stone Company.
Decking: can be the most beautiful feature of the garden, but it can cause many later problems if the installation is not done correctly.
We believe that treatment of the timber can prevent many problems. We use high quality exteriror preservatives and paints to keep your decking look great as long as possible.
Our dedicated team also make sure that everything's built correctly from the base through the frame and srtucture to the surface boards.
We supply and fit hard, softwood and composit decking boards. Depending on the garden, terrace or roof top we can provide and install the most suitable decking to fit the surroundings, preference and budget.
Fencing: Life In The Garden Ltd supply and install timber and conrete fences such as, but not only picket, feather edge, panel, security and private screen fences.
More and more people ask for contemporary style fences. We can deliver high quality finish in a wide range of colour. For advise what kind of fence suits your needs best and budget please contact us.
Driveways: are one of the most popular landscaping work people ask for. However there are many factor to consider. On 1 October 2008 new rules applied for householders wanting to hard surface over their front gardens. If the surface to be covered is more than five square metres, you are required to get planning permission for laying traditional, impermeable driveways that do not control rainwater running off onto roads. This will apply to new driveways, drive extensions or drive replacements. You will not need planning permission if the surface to be covered is less than five square metres, a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally.
No retrospective planning consent is needed for existing driveways and hard surfaces.
Solutions available to avoid the need for planning permission: permeable paving, sustainable drainage systems, porous asphalt, drivegrid driveway system, gravel or a mainly green, vegetated area, traditional hard surfaces with controlled run-off to your garden or lawn or to a purpose-built rain garden or soakaway.
Brickwork: whether to replace your front garden wall, pillars, stairs, retaining walls we have the expertise to complete professional work using both new or reclaimed bricks. We can recommend the best finish suit to surrounding.
Traditional uncovered finish or rendered, painted walls can be done for request.
We also take on repair jobs or repointing.
Footpath: we offer footpath change or new installation for a very competitive price.
We can create your new concrete, paving or tile path in a high standard finish.
Turf installation: from removing the old turf or unvanted vegetation through breaking ground, creating a perfect, even surface to lay the fresh, quality lawn we make sure every step we do professionally.
To keep your newly installed turf in a good condition aftercare is key factor. We advise and even offer maintenance for the grass layed by our team.
For aftercare cost please contact us.
Plant design Planting: the last and also very important stage of landscaping projects to create a sustainable all year interest garden.
Whether it's shady, sun exposed, windy or dry, after considering the conditions we can choose the best possible plant selection for your garden.
We collect information (soil test, site survey, customer survey) and make a planting plan including predictions for all year display and the state of the garden after 1, 2, 5 and 10 years time.
The planting design can include aftercare instructions or we can do regular or follow up maintenance.

This job search has been a bit more difficult than originally anticipated. There is a large overlap between what is done in physics and what is done in data science. Unfortunately, the vocabulary is not quite compatible. So I decided that the best way to showcase my abilities (while keeping them in practice) is to scrape job postings to see what is desired in industry.
In this tutorial, we will begin to scrape indeed.com
to compile a list of sought-after keywords that the current market is looking for. The overarching goal of this is to – other than finding a rewarding career that I absolutely love – do statistical analysis on the vocabulary built out of what’s done here. We will start by using BeautifulSoup
to parse the search results, load them into pandas
dataframes and saving them to .csv
or .json
files to process in the next tutorial.
Note: Not all websites are so welcoming to having their data scraped. Sites like glassdoor, linkedin, facebook, and many others that have personal user information are particularly vigilant when it comes to crawlig/scraping. You can check to see which parts are dis/allowed by adding ‘/robots.txt’ to the main URL (e.g. www.linkedin.com/robots.txt).
Note: The scraper depends on indeed’s website structure which you can parse through by right-clicking anywhere on the website and selecting Inspect (on Chrome, at least). So full discretion, this will not be the most stable way to get job postings from indeed. There is likely a more stable indeed API but I think this is a good exercise in web-scraping which is another important way to gather data. More so, many places will not provide an API to work with.
Let’s get started…
BeautifulSoup
You can follow along
*The interactive notebook requires a google account to save a copy and run on their servers.
import sys
import time
import pandas as pd
import requests
from bs4 import BeautifulSoup
Below are the modules and why we use them:
sys
: Not really important, just a way to print out a progress bar.time
: We use this to really get the date so that we have a time stamp on each file we create. This way, if things break in the future, we still have a working example to apply the next stages.pandas
: If we’re going to be working with a fairly large table of data (memory-limited so if things were much heavier, we’d be querying from a database or some data distribution center), pandas
is currently my favorite way to work with it.requests
: This module pulls a webpage in a format to be used to feed ino BeautifulSoup
(from a URL string with the get()
method).bs4
, BeautifulSoup
: The meat and potatoes that takes the output requests.get()
and allows you to parse through it with its built-in methods.Alright, let’s put the tools to work.
BeautifulSoup
Now that we have our job query going, we want to pull job postings and fill out a table row-by-row with each posting.
So let’s see how we can use BeautifulSoup
to do that. First let’s acknowledge what tools will be using i.e., import the required modules.
Let’s just go ahead and perform a search on indeed for a data scientist position with a minimum annual salary of, let’s say, $20,000 in Boston.
Note the address bar after you submit the search. It should look something, if not exactly, like this:
https://www.indeed.com/jobs?q=data+scientist+%2420%2C000&l=Boston%2C+MA
Let’s break down what and why it looks like this. Our request was to look up job postings for ‘data scientist’ with ‘$20,000’ salary in Boston, MA. Everything after the jobs?q=
reflects just that.
data+scientist
is pretty straightforward.%24
, is the URL escape code for the dollar sign ($).20
and then the escape URL code for the comma %2C
(,).&l=
and Boston, MA
afer it. This indicates an additional requirement for the query to look for job postings where the location variable, &l=
, is Boston, Massachusetts.Knowing this structure allows us to know how to navigate the page without having to be on it and clicking through a series of intermediate steps. Also, this will become important later in this tutorial!
Maybe it’s overkill, but I like to break down each component of the URL in separate variables.
city = 'boston'
job = 'data+scientist'
min_sal = '%2420%2C000'
URL_base = 'https://www.indeed.com/jobs?q=' + job + '+' + min_sal
URL_location = '&l=' + city
URL = URL_base + URL_location
With this URL, let’s grab the results page and feed it into BeautifulSoup
.
First, we use requests
to get the results page. Then we make a BeautifulSoup
class out of the webpage request.
page = requests.get(URL)
soup = BeautifulSoup(page.text, 'lxml')
The webpage is now in a nice class with useful methods that we can use to parse through and extract exactly what we want.
But how does it work? First, we need to know what we want so we can pinpoint what we need from BeautifulSoup
.
We’re going to want to eventually loop over the job postings so let’s identify what that is and see how BeautifulSoup
can help.
Again, let’s inspect our results.
What will be really helpful is Chrome’s cursor tool on the top left (highlighted in blue in the image, left of ‘Elements’ and the mobile view).
When you activate this tool, whatever element you hover over on the page, you’ll see the corresponding HTML that produced it.
Taking a look, we see that when hovering over a single posting (highlighted in green and blue below), the corresponding div
is highlighted on the right hand side
(Yes, it sure does look like an ad but it’s not – it’s a screenshot. Dammit Google!):
And there’s a lot here. There’re a lot of different terms under class
, there’s an id
, there’s different data-
attributes, etc.
As you go through the different postings, you’ll see a couple different things common between all of them.
The class='row'
encompassed and best described the post.
So, using BeautifulSoup
, we can get all of the entries on a single webpage via defining a method:
def get_entries(soup):
# entries = soup.find_all(name='div', attrs={'class':'row'}) # This way we can have a certain criteria
entries = soup.find_all(name='div', class_='row') # This looks cleaner
return entries
entries = get_entries(soup)
The first line in get_entries()
is commented out but it’s another way to get the entries. It uses a dictionary of attributes to select exactly what you want, with multiple criteria.
Instead, we use a – what I personally prefer and find simpler/cleaner – version where you explicitly state the common variables to extract what you want.
This returns a list of entries. At this current time, there are 18 job posting/results for a given page with pagination/links for next few pages of other postings.
For a given posting, what do we want? What immediately comes to mind is the company name, location, salary range, and a description/summary.
Look through a single job posting. There are lot of different attributes. Some obvious, some not. To start off, within the job post, there is a class
with value "title"
.
This is the official job title that the company is seeking. Here are the common ones:
| Class | Description |
|---|---|
title |
Job Title |
sjcl |
Company Info |
location |
Office Location |
salarySnippet |
Salary Range |
summary |
Job Summary |
Some things to note are that the data is not pristine: The format can change from one job posting to another (sjcl
, location
, …) – sometimes the values aren’t even there (salarySnippet
, location
, …)!
Let’s go through and see how we’d use BeautifulSoup
to get one of these values. A more complicated one that comes to mind is the job location.
For one, it’s embedded in the company info. Also, the formatting varies from posting to posting.
The class enclosing the location is the sjcl
. We can get this class from an entry by using the BeautifulSoup
element’s find()
method.
Within an entry, we look for the class 'sjcl'
to pull the company info. Within that, we look for the location by find()
ing the class 'location'
.
def get_location_info(entry):
company_info = entry.find(class_='sjcl')
location_info = company_info.find(class_='location')
location = location_info.text.strip()
...
Loaded into the location
variable is everything within the HTML tags with class="sjcl"
and also within class="location"
.
The last line above extracts the text, not including any of the HTML, CSS, etc from the text
member. Then we additionally use python’s string
method strip
to get rid of excess spaces.
Sometimes, the neighborhood is included. Within the 'location'
, the neighborhood, when there, is found within the 'span'
attribute.
def get_neighborhood(location_info):
neighborhood_info = location_info.find(name='span')
neighborhood = ' '
if neighborhood_info:
neighborhood = neighborhood_info.text
return neighborhood
Finishing our get_location_info()
method, we can extract the location along with the neighborhood.
Let’s look at an example where this is applicable.
We see on the third line of this screenshot is the location information with the neighborhood in parentheses. We’d like to keep the location and neighborhood as separate variables. So we redefine the location with the neighborhood stripped.
def get_location_info(entry):
...
# Extract neightborhood info if it's there
neighborhood = get_neighborhood(location_info)
location = location.rstrip(neighborhood)
neighborhood = neighborhood.strip('()')
return location, neighborhood
test_job_entry = entries[0]
location, neighborhood = get_location_info(test_job_entry)
The job summary is nice but it’s often cut much too short: there is some word or character limit. Some descriptions don’t get to the substantial part until a bit later so the summary is inadequate. Getting the full job description is much trickier.
Getting the summary is simply:
def get_job_summary(entry):
return entry.find(class_='summary').text.strip()
But we can go beyond that!
To get the full job description, we have to click on the job posting to go to the page of the actual posting.
Now, note the link. It may be a nasty thing.
https://www.indeed.com/viewjob?jk=466c648cf7a22a50&tk=1dkuk8nat0gc8000&from=serp&vjs=3&advn=6613095622180756&adid=77005642&sjdu=teYnAu8OgCGxABCwWD3OBGSvNPsXXaEnWLrUq8268_Q7hC0YDHACZYjlfAZ2VvRY5EESrqlz1VwWF8YSqa7ebseSPxZCuEl0hMQipV1VPT6vIRhbN2jzOprwFHzzg5eqCVENzzZ9i-4GTmNHGSUnm5ZkpfgPbmXOGU2P7n50pq-C5LGpOJGmAL5Loqy_5pM1WIA2dUwXdF02ymLel9jAy22GfZafOde6nrdo-YH9JMgK4xylf_Z_R6MGkuLZCpCX
How are we going to work with this beastly thing and do it so in an automated way? Well, from our experience earlier, we saw that there’s a lot of information in the URL.
Maybe we don’t know what all of the tokens mean but we do know that the variables are separated by &var=
, where var
is some variable. What’s more, if you’ve been observant
when looking through the individual job posting from our results page, you’ll see that the value from the attribute name data-jk
is a unique id that also appears in the URL!
And where does it show up? It shows up after viewjob?
and subsequently after the URL variable jk=
.
Try getting rid of everything except that. What you’re left with is this:
https://www.indeed.com/viewjob?jk=466c648cf7a22a50
and gets you to the same page. I assume the rest of the URL is for tracking and statistics purposes to understand what was the most effective way to bring you to the job posting.
Using this information along with knowing how to extract text from a webpage, we can add in functionality to go beyond the job summary and extract the job description.
First, we get the unique id or link.
def get_link(entry):
link = entry['data-jk']
return link
URL_job_desc = 'https://www.indeed.com/viewjob?jk=' + get_link(test_job_entry)
Now we can use what we’ve done before to navigate to that page and pull the data that we want. Again, navigate to the page and inspect it.
If we have the unique link, we can navigate straight to the page using request.get()
again. This time, let’s include a pause with time.sleep()
so that we do not
trigger any response due to “suspicious” web traffic.
From my experience, the job description page is particularly messy. This is probably due to recruiters using
– likely – internal job postings with a certain format. Regardless, we can pull the text, touch it up now, and worry about the rest during the data cleaning stage.
Just scanning a few examples, we see that many of the C escape sequences like \n
and \t
– a clear sign of copying and pasting the posting from different sources.
def get_job_description(job_page):
page = requests.get(job_page)
time.sleep(1) # Ensuring at least 1 second between page grabs
soup = BeautifulSoup(page.text, 'lxml')
description = soup.find(name='div', class_='jobsearch-jobDescriptionText')
description = description.text.strip()
description = description.replace('\n',' ')
description = description.replace('\t',' ')
return description
description = get_job_description(URL_job_desc)
I won’t go into each of these and feel free to leave a comment if you have any questions to clear anything up.
I mix it up between using the dictionary way to gather (attr=
) and using variables directly (class_=
).
There are also some methods with try:
and except:
. These are used to consider entries where the variable is subject
to change. If it’s not there, returning a None
or a NaN
can break the entire program.
def get_job_title(entry):
job_title_container = entry.find(name='a', attrs={'data-tn-element':'jobTitle'})
job_title = job_title_container.text
return job_title.strip()
def get_company(entry):
company_list = []
try:
test_entry = entry.find(class_='company')
company_list.append(test_entry.text.strip())
company = company_list.pop()
except:
try:
test_entry = entry.find(class_='result-link-source')
company_list.append(test_entry.text.strip())
company = company_list.pop()
except:
company = ' '
return company
def get_location_info(entry):
company_info = entry.find(class_='sjcl')
location_info = company_info.find(class_='location')
location = location_info.text.strip()
# Extract neightborhood info if it's there
neighborhood = get_neighborhood(location_info)
location = location.rstrip(neighborhood)
neighborhood = neighborhood.strip('()')
return location, neighborhood
def get_neighborhood(location_info):
neighborhood_info = location_info.find(name='span')
neighborhood = ' '
if neighborhood_info:
neighborhood = neighborhood_info.text
return neighborhood
def get_salary(entry):
salary_list = []
salary = ''
try:
salary_list.append(entry.find('nobr').text.strip())
salary = salary_list.pop()
except:
try:
salary_container = entry.find(name='div', class_='salarySnippet')
salary_temp = salary_container.find(name='span', class_='salary')
salary_list.append(salary_temp.text.strip())
salary = salary_list.pop()
except:
salary = ' '
return salary
def get_job_summary(entry):
return entry.find(class_='summary').text.strip()
def get_link(entry):
link = entry['data-jk']
return link
def get_job_description(job_page):
page = requests.get(job_page)
time.sleep(1) # Ensuring at least 1 second between page grabs
soup = BeautifulSoup(page.text, 'lxml')
description = soup.find(name='div', class_='jobsearch-jobDescriptionText')
description = description.text.strip()
description = description.replace('\n',' ')
description = description.replace('\t',' ')
return description
Now that we have all the methods we need to grab the relevant information, we can go ahead and make a list to loop through to extract several postings from several cities.
Again, looking at the results page, we see 18 postings per page. Since this is a variable based off indeed, let’s name the variable POSTINGS_PER_PAGE
.
We’re looking to loop over cities we’re interested in and then loop over pages and loop over postings within the page.
From there, we’ll construct a pandas
dataframe with the variables that we’ll use in our machine learning and analysis stage.
max_pages_per_city = 60
POSTINGS_PER_PAGE = 18 # Indeed's default 18 entries per page
postings_per_city = max_pages_per_city * POSTINGS_PER_PAGE
columns = ['job_title', 'company_name', 'location', 'neighborhood', 'description', 'salary', 'link']
df = pd.DataFrame(columns = columns)
I’m personally only interested with job postings in and around Boston so I’ll only include that in my city_set
but this can be extended for your own use.
URL_base = 'https://www.indeed.com/jobs?q=data+scientist+%2420%2C000'
# Loop over cities
city_set = ['Boston']
for city_targ in city_set:
URL_location = '&l=' + city_targ
# Loop over pages
for page_number in range(0, postings_per_city, POSTINGS_PER_PAGE):
URL_page_start = '&start=' + str(page_number)
URL = URL_base + URL_location + URL_page_start
page = requests.get(URL)
time.sleep(1) # Ensuring at least 1 second between page grabs
soup = BeautifulSoup(page.text, 'lxml')
# Loop over posts/entries
entries = get_entries(soup)
for i,entry in enumerate(entries):
sys.stdout.write('\r' + ' page: ' + str(page_number//POSTINGS_PER_PAGE)
+ ' / ' + str(max_pages_per_city)
+ ', job posting: ' + str(i) + ' / ' + str(len(entries))
)
title = get_job_title(entry)
company = get_company(entry)
location, neighborhood = get_location_info(entry)
salary = get_salary(entry)
link = get_link(entry)
job_page = 'https://www.indeed.com/viewjob?jk=' + link
description = get_job_description(job_page)
# Append the new row with data scraped
i_next = len(df) + 1
df.loc[i_next] = [title, company, location, neighborhood, description, salary, link]
import datetime
date = str(datetime.date.today())
# Saving dataframe as local csv file
df.to_csv(date + '_indeed-ds-postings.csv', encoding='utf-8')
At the very end, we save the data in a comma-separated values (CSV) format with the date to be used in the next stages. The date is important to not overwrite your data on different days but also if there are any changes to indeed’s website formatting, we still have a working copy to work with for the next stages, with the present scripts.

Fish pie meets jacket potato in this easy family lunch recipe.
Preheat the oven to 200C/185C Fan/Gas 6. Wash the potatoes well, dry them and prick several times with a fork. Pour some olive oil into your hands and rub over the potatoes. Make four small mounds of sea salt on a baking tray and sit a potato on each one. Bake for 50 minutes–1 hour, or until crispy and cooked.
Meanwhile, for the filling, put the milk, garlic and bay in a saucepan, season and bring to a simmer. Add the cod and cook gently for 4 minutes, then remove from the heat. Lift out the cod using a slotted spoon and place on a plate. Pour the milk mixture into a jug.
Let the potatoes cool slightly, then cut them in half lengthways. Scoop out the flesh and put it in a bowl. Flake the cod and add to the potato. Mix in the parsley. Add 150ml/5fl oz of the milk and mash using a potato masher. Add a little more milk if the mixture is too stiff, but don’t let it become sloppy.
Spoon the flesh back into the potato skins and scatter the cheese on top. Place on a baking tray and bake for 25 minutes, or until piping hot and golden.
Serve immediately, drizzled with a little olive oil, with lemon wedges and watercress.


No. I am not talking about your financial portfolio or your financial literacy. I am not talking about index funds, mutual funds, hedge funds or your Roth IRA.
If you were expecting a quick rundown on how to properly invest your earnings for future wealth, welp, I'm sorry....but you are SOL.
What I am talking about is far more important...
I am about to reveal to you the meaning of Life....
HA. Kidding. But I digress...
Rather than just telling the purpose of this post I would rather illustrate it with a story from my lovely past (because everyone loves stories...right?):
I was raised in Cincinnati, Ohio. (Yes, that means I love the Bengals and the Reds :) )
My father was a chemical engineer and my mother was a teacher. Both of them raised me to always be a person of integrity and a hard worker.
At the age of 13 my father set me up with my first job as a paper boy...figuring this would teach me what it means to be a hard worker. There were around 75 houses in my route that I was responsible for. My job was simple: once a week I would deliver a paper to each house that was highlighted on the route map and at the end of the month I would walk door-to-door and collect the money that was owed to me (I believe it was $2.50/house at the time).
I would then go back to my house and dump out all the money in my pockets onto the kitchen table. Out of each house I collected from I was allowed to keep 50% of the earnings.
I followed this same process for a while until I started getting tired of making only $40 per month. I wanted more which meant I needed to convince more houses in my route to start buying the paper.
Upon looking at my route map I realized that more than half of the houses that were previously highlighted had a black X over them meaning they didn't want to receive the paper anymore. This left me very perplexed as I loved reading the paper! (or at least looking at the pictures as I was only 13)
I kept thinking.....and thinking....and thinking....of ways I could solve this problem.
AHA!
It finally came to me...if I wanted to get more houses to buy the paper, I would have to show the "Black X" houses how great the paper actually was. Turns out....around the time I had this idea, the local high school football team had made the state playoffs.
What a great opportunity! I would give the paper to all of the "Black X" houses with a note inside saying "FOR FREE! -Ian" so everyone in my route could see how the local football team was progressing in the playoffs. This way they would see how great the paper really was and maybe....just maybe...change their minds and start buying the paper in the future.
So that is exactly what I did...for 4 weeks I delivered papers with hand-written notes inside them to all of the "Black X" houses. I ended up losing money that month.
However, on the 5th week (the 1st week of the next month) something magical happened. I'll never forget it.
RING RING...RING....RINGGGGGGG!
Our corded home-phone (yes those existed at one point) would not stop ringing! All of the houses who I had paid for to get the paper for free kept calling, asking me to sign them back up to receive the paper!!
What an awesome lesson I learned that week. If you want to experience returns you first have to invest...
 We each have a limited amount of time on this earth...invest your time in activities that matter.
Every startup founder in the world has their own story of how they worked 20 hour days for weeks on end...how their diet turned into Monster energy drinks and pretzel sticks....how they sat staring at a computer screen until they started drooling down their chin...
These are the facts. If you want to be successful in business, in industry or as an entrepreneur you MUST force yourself to begin investing your time...because you simply can't get it back.
Here is my top 5 list of items you should begin investing your time in for the 20 and 30 somethings:
1. Reading
I used to hate reading books. Sitting in one place for multiple hours only to flip one page after the other terrified me. However, after giving it another try I can honestly say reading is one of the most valuable habits to get into. Imagine sitting at the table during an investor dinner...everyone begins talking about macroeconomics and socialism vs. capitalism.  Believe it or not, this can have a major affect on whether you raise that initial 120k in seed investments. Know a little about a lot and you'll do just fine.
2. Relationships
This goes hand-in-hand with expanding your network. The vast majority of jobs are actually found through personal relationships...not through submitting your resume online or placing it in your University's Career Services dropbox.
3. Education
For the love of God...stop playing video games 6 hours/day and begin educating yourself. Start teaching yourself new things and increasing your skill-set. If you do this, I promise the only regret you will have is not starting earlier. Learn Photography, Adobe Photoshop and Illustration, what goes into creating a website, how to solve a Rubik's cube, how to play an instrument, how to change a flat tire....and the list goes on forever. And the beautiful thing is all of this can be found by a simple Google Search.
4. Financial Literacy
This is always a tough one. Simply put: everything in life costs money. In order to stay above water you must develop a strategy for handling your income and tracking your expenses. Know what your monthly expenses are, know what you spend money on, create a budget spreadsheet and start taking care of your money. If you are looking for a place to start I always love recommending Rich Dad, Poor Dad.
5. Experiencing the World
Guess what?! There are 196 countries and over 4,000 religions in the world we live in. Experience as many of them as you can. Do not be ignorant. Read the news and have at least a baseline knowledge of what is going on in the world and plan time to travel! There is a world out there beyond the comfort of your bed.
At the end of the day...It comes down to a choice.
Choose to sit on your couch with a bag of Jalepeno Cheddar Cheetos watching seasons 1-3 of Game of Thrones or get out there and begin experiencing life, begin creating and begin investing your time in activities that will pay dividends in the future.
If you are still reading I assume I have at least said something that resonates you. Don't shove that drive and energy you feel now into a box...harness it and let it fuel you forward.
What separates the people that actually do things from the people that just dream about doing things is they act. And they fail. And they act again. They never become complacent and they never stop moving forward. And neither should you.
 That is a very limited life. Life can be much broader once you discover one simple fact.  And you can change it, you can influence it, you can build your own things that other people can use...It's to shake off this erroneous notion that life is there and you're just gonna live in it, versus embrace it, change it, improve it, make your mark upon it."

#volume_used_in_bytes ⇒ Integer
(rw)
The size of the data stored on the volume in bytes. This value is
calculated based on the number of blocks that are touched, instead
of the actual amount of data written. This value can be useful for
sequential write patterns but less accurate for random write
patterns. VolumeUsedInBytes
is different from the compressed size
of the volume, which is the value that is used to calculate your
bill.
If you use a delete tool that overwrites the data on your volume with random data, your usage will not be reduced. This is because the random data is not compressible. If you want to reduce the amount of billed storage on your volume, we recommend overwriting your files with zeros to compress the data to a negligible amount of actual storage.
