As the solution architect for the manufacturing company, you now want to start moving the ERP app and database servers to Azure. As a first step, you're going to test out your network security plan, using two of your servers.
In this unit, you'll configure a network security group and security rules to restrict network traffic to specific servers. You want your app server to be able to connect to your database server over HTTP. You don't want the database server to be able to use HTTP to connect to the app server.
Important
You need your own Azure subscription to run this exercise, and you might incur charges. If you don't already have an Azure subscription, create a free account before you begin.
First, you'll create a resource group, the virtual network, and subnets for your server resources. You'll then create a network security group.
Open the Azure Cloud Shell in your browser, and log in to the directory with access to the subscription you want to create resources in. Use the Bash version of Cloud Shell.
To create a variable to store your resource group name, and a resource group for your resources, in the Cloud Shell, run the following command. Replace <resource group name>
with a name for your resource group, and <location>
with the Azure region you'd like to deploy your resources in.
Find the location name with the following command.
az account list-locations -o table
rg=<resource group name>
az group create --name $rg --location <location>
To create the ERP-servers virtual network and the Applications subnet, in the Cloud Shell, run the following command.
az network vnet create \
--resource-group $rg \
--name ERP-servers \
--address-prefix <IP_ADDRESS>/16 \
--subnet-name Applications \
--subnet-prefix <IP_ADDRESS>/24
To create the Databases subnet, in the Cloud Shell, run the following command.
az network vnet subnet create \
--resource-group $rg \
--vnet-name ERP-servers \
--address-prefix <IP_ADDRESS>/24 \
--name Databases
To create the ERP-SERVERS-NSG network security group, in the Cloud Shell, run the following command.
az network nsg create \
--resource-group $rg \
--name ERP-SERVERS-NSG
Next, you'll create two VMs called AppServer and DataServer. You deploy AppServer to the Applications subnet, and DataServer to the Databases subnet. Add the VM network interfaces to the ERP-SERVERS-NSG network security group. Then, to test your network security group, use these VMs.
To build the AppServer VM, in the Cloud Shell, run the following command.  For the admin account, define a <password>
.
az vm create \
--resource-group $rg \
--name DataServer \
--vnet-name ERP-servers \
--subnet Databases \
--nsg ERP-SERVERS-NSG \
--size Standard_DS1_v2 \
--image UbuntuLTS \
--admin-username azureuser \
--custom-data cloud-init.yml \
--admin-password <password>
It can take several minutes for the VMs to be in a running state. To confirm that the VMs are running, in the Cloud Shell, run the following command.
az vm list \
--resource-group $rg \
--show-details \
--query "[*].{Name:name, Provisioned:provisioningState, Power:powerState}" \
--output table
When your VM creation is complete, you should see the following output.
Name Provisioned Power
---------- ------------- ----------
AppServer Succeeded VM running
DataServer Succeeded VM running
Now, you'll try to open a Secure Shell (SSH) session to each of your VMs. Remember, so far you've deployed a network security group with default rules.
To connect to your VMs, use SSH directly from Cloud Shell. To do this, you need the public IP addresses that have been assigned to your VMs. To list the IP addresses that you'll use to connect to the VMs, in the Cloud Shell, run the following command.
az vm list \
--resource-group $rg \
--show-details \
--query "[*].{Name:name, PrivateIP:privateIps, PublicIP:publicIps}" \
--output table
To make it easier to connect to your VMs during the rest of this exercise, assign the public IP addresses to variables. To save the public IP address of AppServer and DataServer to a variable, in the Cloud Shell, run the following command.

To check whether you can connect to your DataServer VM, in the Cloud Shell, run the following command.
ssh azureuser@$DATASERVERIP -o ConnectTimeout=5
You'll get the same connection failure message.
Remember that the default rules deny all inbound traffic into a virtual network, unless this traffic is coming from the same virtual network. The Deny All Inbound rule blocked the inbound SSH connections you just attempted.
Inbound
As you've now experienced, the default rules in your ERP-SERVERS-NSG network security group include a Deny All Inbound rule. You'll now add a rule so that you can use SSH to connect to AppServer and DataServer.
To create a new inbound security rule to enable SSH access, in the Cloud Shell, run the following command.
az network nsg rule create \
--resource-group $rg \
--nsg-name ERP-SERVERS-NSG \
--name AllowSSHRule \
--direction Inbound \
--priority 100 \
--source-address-prefixes '*' \
--source-port-ranges '*' \
--destination-address-prefixes '*' \
--destination-port-ranges 22 \
--access Allow \
--protocol Tcp \
--description "Allow inbound SSH"
To check whether you can now connect to your AppServer VM, in the Cloud Shell, run the following command.
ssh azureuser@$APPSERVERIP -o ConnectTimeout=5
The network security group rule might take a minute or two to take effect. If you receive a connection failure message, try again.
You should now be able to connect. After the Are you sure you want to continue connecting (yes/no)?
message, enter yes
.
Enter the password you used when you created the VM.
Close the AppServer session, enter exit
.
To check whether you can now connect to your DataServer VM, in the Cloud Shell, run the following command.
ssh azureuser@$DATASERVERIP -o ConnectTimeout=5
You should now be able to connect. After the Are you sure you want to continue connecting (yes/no)?
message, enter yes
.
Enter the password you used when you created the VM.
To close the DataServer session, enter exit
.
Now, add a rule so that AppServer can communicate with DataServer over HTTP, but DataServer can't communicate with AppServer over HTTP.  AppServer should be able to communicate with DataServer over HTTP. DataServer shouldn't be able to communicate with AppServer over HTTP.
To connect to your AppServer VM, in the Cloud Shell, run the following command. Check if AppServer can communicate with DataServer over HTTP.
ssh -t azureuser@$APPSERVERIP 'wget http://<IP_ADDRESS>; exit; bash'
Enter the password you used when you created the VM.
The response should include a 200 OK
message.
To connect to your DataServer VM, in the Cloud Shell, run the following command. Check if DataServer can communicate with AppServer over HTTP.
ssh -t azureuser@$DATASERVERIP 'wget http://<IP_ADDRESS>; exit; bash'
Enter the password you used when you created the VM.
This shouldn't succeed, because you've blocked access over port 80. After several minutes, you should get a Connection timed out
message. To stop the command before the timeout, press Ctrl+C.
Next, create an app security group for database servers, so that all servers in this group can be assigned the same settings. You're planning to deploy more database servers, and want to prevent these servers from accessing app servers over HTTP. By assigning sources in the app security group, you don't need to manually maintain a list of IP addresses in the network security group. Instead, you assign the network interfaces of the VMs you want to manage to the app security group.
To create a new app security group called ERP-DB-SERVERS-ASG, in the Cloud Shell, run the following command.
az network asg create \
--resource-group $rg \
--name ERP-DB-SERVERS-ASG
To associate DataServer with the app security group, in the Cloud Shell, run the following command.
az network nic ip-config update \
--resource-group $rg \
--application-security-groups ERP-DB-SERVERS-ASG \
--name ipconfigDataServer \
--nic-name DataServerVMNic \
--vnet-name ERP-servers \
--subnet Databases
To update the HTTP rule in the ERP-SERVERS-NSG network security group, in the Cloud Shell, run the following command. It should reference the ERP-DB-Servers app security group.
az network nsg rule update \
--resource-group $rg \
--nsg-name ERP-SERVERS-NSG \
--name httpRule \
--direction Inbound \
--priority 150 \
--source-address-prefixes "" \
--source-port-ranges '*' \
--source-asgs ERP-DB-SERVERS-ASG \
--destination-address-prefixes <IP_ADDRESS> \
--destination-port-ranges 80 \
--access Deny \
--protocol Tcp \
--description "Deny from DataServer to AppServer on port 80 using application security group"
To connect to your AppServer VM. in the Cloud Shell, run the following command. Check if AppServer can communicate with DataServer over HTTP.
ssh -t azureuser@$APPSERVERIP 'wget http://<IP_ADDRESS>; exit; bash'
Enter the password you used when you created the VM.
As before, the response should include a 200 OK
message. The app security group settings can take a minute or two to take effect. If you don't initially receive the 200 OK
message, wait a minute and try again.
To connect to your DataServer in the Cloud Shell (at the top-right in Azure; the box with the >_) , run the following command. Check if DataServer can communicate with AppServer over HTTP.
ssh -t azureuser@$DATASERVERIP 'wget http://<IP_ADDRESS>; exit; bash'
Enter the password you used when you created the VM.
As before, this shouldn't succeed, because you've blocked access over port 80. After several minutes, you should get a Connection timed out
message. To stop the command before the timeout, press Ctrl+C.
You've now confirmed that your network security group rule works using an app security group, in the same way as when you used a source IP address. If we were to add additional data servers, you can easily ensure they have the proper network security by adding the new servers to the ERP-DB-SERVERS-ASG.

Ruby Classes
1.15.2016When working with objects that share similar characteristics but are different from each other, classes can offer simplicity and organization. Classes can hold a number of variables and methods that are specific to that class object. Let's make a class to keep track of all of the books in your library! We start by defining our new class and what it should do when we make an instance of one. We can also define the title and author when we create a new book. Classes use both local and instance variables. Local variables, as their name suggests, are limited to the method they're a part of. Instance variables however are available to the entire instance or specific object of that class. Instance variables are denoted with the @ symbol.
class BooksHere we have created our class Books, which requires two arguments upon creation. It then sets instance variables those arguments equal to the supplied arguments. To call an instance of our new class. type:
def initialize(title, author)
@title = title
@author = author
end
end
first_book = Books.new("Ulysses", "James Joyce")
Our class doesn't do much right now, so let's add some more to it! Instance variables are shared across the object, so let's create some methods to access their value so other methods can reference them as well. We'll do this with a rather simple method that looks like this:
def titleNow whenever you call the method
@title
end
def author
@author
end
title
, it will return @title
and similarly for
author
.
Okay, that's great but our class still doesn't do much.
def infoNow we can call our
puts title + "," + author
end
info
on a class we've created and it will print out the title and author
first_book.infoLike instance variables, these are instance methods. They are available to the entire instance of this particular class. As you can imagine we could create more methods to add more information to our class like publisher, copyright date, plot, etc.


Quickly understand of ACTS models
When you write a test case, you need to prepare some database tables, request parameter data of methods, or data for validating database tables and responses. You can save such data in models, and import it to preparation data or validation data when you edit the test case. This allows you to conveniently reuse data. Currently, ACTS models can be divided into database models and class models.
In conventional test case compilation, data preparation of models, such as database models, request parameter models, and response models, is based on the test code. The complexity of models increases with the business complexity, especially in financial-level business applications, where a class or data table may have dozens of properties or fields, and where class nesting is common. In this case, constructing complex objects is extremely difficult and prone to omissions. Some of the most frequently occurring problems are listed as follows:
- Omissions may occur and troubleshooting takes a lot of time for a large number of tables.
- Field names of tables are difficult to remember, and spelling errors frequently occur.
- The large number and complex types of interface request parameters are frustrating.
- There are so many class properties that important properties are prone to omission.
- Object construction with nested structures requires continuous effort in creating and setting values.
- Important properties are easily omitted when the inheritance and implementation relationships are complex.
ACTS models can effectively address the above problems by formatting classes and tables in CSV, which makes the structure of classes easier to understand. Class models and data table models can help you quickly create objects, and serialize them into the YAML file. ACTS models allow you to conveniently manage test case data.
Storage location of models
You can view existing models under the resource/model directory of the test module.

Y: indicates that the data is to be inserted.
N: indicates that the data is not to be inserted.
C: indicates that ACTS will clean the inserted data by taking this value as the where condition.
F: indicates that the value of this column is a database function.
L: indicates that a large field data record requires line wrap. The preparation method for this data record is: A=B;C=D.
2. Quickly import data from models during test case editing
When editing database table data (including preparing table data and expectation data) in ACTS IDE, you can right click to add a model of the specified table, to import all fields and values of the specified table directly from the CSV file of the table model for quick editing. For more information about the use of DB models, see Prepare database data.

A complex object is a closed package that contains not only its own model but also the models of its nested objects.
ACTS uses models to quickly import data and edit complex objects (including request parameters, responses, and exceptions). You can right click a class model in ACTS IDE to construct objects of this class, and assign values to these objects for quick editing.
Generate object model
You can generate an object model by using one of the following methods: 1. Right click any method defined in the class that you want to generate the object model for. 1. Right click any method defined in the interface as shown in the following figure.
If you use IDEA, ensure that your code has been compiled. IDEA does not automatically compile your code and you need to manually proceed with mvn clean install
, or enable the automatic compilation function by choosing File > Settings > Build,Execution,Deployment > Compiler > Make project automatically.
Generate object model in ACTS IDE
(1) Right click any method defined in the class that you want to generate the object model for.

Former Cumberland and Circle Traders Pool Money for Crypto Prop Trading
by Brad KeounDan Matuszewski remembers the early days of cryptocurrency trading, just a handful of years ago. It wasn’t the possibility of a market correction that worried him. It was the risk that the whole business might disappear.
“There was always a non-zero chance that bitcoin would gap down, die, and never come back,” Matuszewski, 31, said in a phone interview.
Matuszewski, who previously oversaw trading at the cryptocurrency-focused financial company Circle, says he’s now confident enough in the market’s future that he’s teamed up with two partners to pool more than $10 million to start a proprietary-trading firm. They are Bobby Cho, 35, former head of trading at brokerage firm DRW’s Cumberland crypto unit, and Julien Collard-Seguin, 31, a former technology executive at Circle.
According to Cho, the new company, called CMS Holdings, started trading in October. The business is registered in the Cayman Islands and doesn’t manage money from outside investors, he said.
“We deploy strategies much like a hedge fund in the market, except that we’re not structured as such,” Cho said.
The plan is to put 30 percent of the firm’s money into highly liquid cryptocurrencies like bitcoin and ethereum and 40 percent to 50 percent into less-frequently traded tokens and digital assets, Cho said. The rest would likely go into long-term equity investments in the crypto industry, he said.
“The space is evolving very quickly, and it’s not stopping,” Cho said.
Bitcoin’s price has more than doubled this year to about $8,700 each, though it’s still well off the record of about $20,000 reached in 2017.
Said Matuszewski:
“It’s a lot safer now, in that it’s probably not going to disappear.”

There's a buzz about wax wrap at beekeeper's meeting
The Tiverton Beekeepers had a demonstration by Norma King on how to make Wax Wraps
by Lewis ClarkeBeekeepers have said goodbye to clingfilm as they welcomed wax wraps.
The Tiverton Beekeepers had a demonstration by Norma King on how to make Wax Wraps, at their November branch meeting.
Speaking to the group, Norma King said: “All you need is 60,000 bees to produce you some spare beeswax - or know a friendly beekeeper - a coconut, a Bain Marie, an old iron and to follow Norma’s instructions.
“Basically, you need about 200 grams of beeswax, 20 grams of coconut oil. Heat them together in a jug standing in a pan of boiling water. When melted, use a paintbrush to spread the mixture on a piece of clean cotton cloth, cover with a piece of greaseproof paper and iron away! After about 30 seconds, the wax mixture will have spread evenly and soaked into the cloth. Hey presto, you have made something in which to wrap your sandwich.
“Wraps can also be used to cover containers to put into the fridge and store food.
“The great thing about wax wraps is not just the fun of making your own Christmas presents, but also they can be washed in warm - not hot - water and reused many times.
“Eventually, they can be composted, so no harm to the environment.”

--- layout: layout-sidebar order: 13 name: Create a tabbed page files: js: - /assets/js/tabbedpage.js ---
Now that we know how to create a record page, lets look at how to create the other common page type in {{ stache.config.product_name_short }}: a tabbed page. While record pages display data for individual records, tabbed pages usually serve as overviews for multiple records. For example, tabbed pages can display lists of constituents or gifts.
{{ stache.config.product_name_short }} uses the UI Bootstrap Tabs module to display tabs. It adds {{ stache.config.product_name_short }}-specific functionality with its tabset module.
In this example, we have two tabs. Each tab displays a list of records, and to display the number of records beside the tab headers, we use the .bb-tab-header-count
CSS class. And to display tab content from edge to edge and give the tabs themselves a margin, we add the .bb-page-tabs
CSS class.
{{ include "includes/create-a-tabbed-page/tabs.html" escape=true }}
Now that we've covered the two basic page types, we can proceed to the Components section for more information about the components that we can include on each page type.

The EXTERNSHEET record specifies externally referenced workbooks. In BIFF7 and earlier, multiple EXTERNSHEET records form a table in the file. The cxals field of the EXTERNCOUNT record specifies the number of EXTERNSHEET records. You should not change the order of EXTERNSHEET records.
In BIFF8, the SUPBOOK record stores the encoded pathname and file name. There is one SUPBOOK record for each externally referenced workbook. The EXTERNSHEET record contains a table ( rgXTI ) that points to the SUPBOOK records. Several ptg s in a BIFF8 formula contain an ixti field; this is the 0-based index to the rgXTI table in the EXTERNSHEET record.
An externally referenced workbook is called a source workbook. The workbook that refers to it is called a dependent workbook.

chEmpty indicates the file name is an external reference to an empty workbook name, as in the formula =Sheet1!$A$1 .
chSelf indicates the file name is an external reference in which the dependent and source workbooks are the same. An example of this is the workbook SALES.XLS, which contains the formula =SALES.XLS!$A$1 .
A chDDE key ( 03h ) can occur in the rgch field; it is not necessarily the first character in the field, as are chEmpty , chEncode , and chSelf . This key indicates that the external reference is a DDE or OLE link. In a DDE link, the chDDE key replaces the | (pipe) character that separates the DDE application and topic. In an OLE link, chDDE separates the classname and file name.
A chEncode at the beginning of rgch indicates the file name of the source workbook was encoded to a less system-dependent file name. The special keys listed in the following table are recognized in the rgch field.
|
Key Name |
Value |
PC file systems |
|
chVolume |
01 |
Represents an MS-DOS drive letter. It is followed by the drive letter. For example, the formula =‘D:\SALES.XLS’!A1 generates the chVolume key when the dependent workbook is not on the D drive. UNC file names, such as \\server\share\myfile.xls , generate an @ character after the chVolume key; this replaces the initial double backslash (\\). |
|
chSameVolume |
02 |
Indicates the source workbook is on the same drive as the dependent workbook (the drive letter is omitted). For example, the formula =‘\SALES.XLS’!A1 generates the chSameVolume key when the dependent workbook is not in the root directory. |
|
ChDownDir |
03 |
Indicates the source workbook is in a subdirectory of the current directory. For example, the formula =‘XL\SALES.XLS’!A1 generates the chDownDir key. The subdirectory name precedes the chDownDir key, and the file name follows it. |
|
chUpDir |
04 |
Indicates the source workbook is in the parent directory of the current directory. For example, the formula =‘..\SALES.XLS’!A1 generates the chUpDir key. |
|
chLongVolume |
05 |
(Not used) |
|
chStartupDir |
06 |
Indicates the source workbook is in the startup directory (the Xlstart subdirectory of the directory that contains Excel.exe). |
|
chAltStartupDir |
07 |
Indicates the source workbook is in the alternate startup directory. |
|
chLibDir |
08 |
Indicates the source workbook is in the Library directory. |

Hadoop
Apache Hadoop is a set of algorithms (an open-source software framework written in Java) for distributed storage and distributed processing of very large data sets (Big Data) on computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures (of individual machines, or racks of machines) are commonplace and thus should be automatically handled in software by the framework.The core of Apache Hadoop consists of a storage part (Hadoop Distributed File System (HDFS)) and a processing part (MapReduce). Hadoop splits files into large blocks (default 64MB or 128MB) and distributes the blocks amongst the nodes in the cluster. To process the data, Hadoop Map/Reduce transfers code (specifically Jar files) to nodes that have the required data, which the nodes then process in parallel.

Big data
Brief theretical explanation
hwo big data has been used by industries from century


The fitness tracker industry has a problem: people love wearing their devices, but after a while, knowing how many steps you've walked gets boring. What if your Apple Watch or Fitbit did more than track your fitness - and made your mind a little bit healthier too?
Quick: mark how you feel - right now - out of ten. Ten is good, zero is bad. Remember this for later.
Chris Dancy records everything.
He feeds all of the data from his life into a special Google Calendar. From the week view, it looks like a crazed Piet Mondrian painting, packed with tiny colourful squares, squashed up next to each other. They seem randomly scattered, and yet the eye can detect a vague order.

Each calendar entry is a datapoint. The calendar is a dashboard, showing every bit of data Chris records.
Zoom out, and the calendar doesn’t just show Chris’ life - it is Chris’ life. Crazed but ordered. Obsessive, but thoughtful.
Chris Dancy created hundreds of ways to track and record data about him, his actions, and his dogs.
He used pretty much every off-the-shelf consumer tracking kit you can think of. Fitness trackers, smartwatches, and heart rate monitors were all in Chris’ toolbox - and for his pooches, a dog-tracking GPS system called Tagg. He also built his own tracking systems that recorded, for example, his mood at any given time, how many emails he read and sent, and what the weather was like.
It changed his life.
En route, he lost a load of weight, and gained a sharp hairdo, a sharper wardrobe and the ability to take better selfies.
Chris, before and after he started recording his data, via Flickr
Chris might now be the world’s most connected human. In a world where people vacillate between fear of using online services due to privacy concerns, and blindly over-sharing personal info on social media, this is not a straightforward boast.
But wait, you cry, I do most of this stuff already! I keep track of my finances in a notebook, watch my weight using good old-fashioned scales, and I use a FitBit - I just don’t call myself a “quantified human.”
Well, yes - that’s kind of the point. Because what Chris is doing now is taking lots of simple data points - just like the ones you record - then squashing them together, slicing them back up, and using them to make really useful things happen in his life.
Maybe you won’t be aware of it, but very soon, you’ll be doing the same thing and experiencing, to quote the Wu-Tang Clan, a better tomorrow.
In his personal FAQs, Chris names a few simple things he learnt as he started out on his quest to be hyper-connected:
- How late I could have a drink without getting up to pee in the middle of the night.
- How what I did on social media, and how I spent my time online, related to how much I did or didn’t exercise.
- How the nutritional value of my food stacked up against the money I spent on that food and the time it took to acquire.
And in this neat trio, Chris happens to also outline the three stages of Data-Overload Distress:
Usefulness -> anxiousness -> obsessiveness
Usefulness: Knowing when to stop drinking before bedtime is useful!
Anxiousness: But over-analysis of your public actions is unhelpful!
Obsessiveness: And when you start viewing food as value-for-money human-fuel, you’ve landed right in the Soylent wheelhouse.
 He warns of how easy it is to unwittingly stroll down the data-driven path to unwanted, unintended, obsession.
It’s a warning that we could all probably heed.
“My life had become a Wikipedia of me.”
Virtually none of us are fully aware of the wild nature of our existing personal data-storm. But be sure that it does put stresses on our lives.
How many likes did your Instagram post get and what did it make you feel? How do you feel when your fitness tracker nudges you to go for a run and you swipe the notification away instead?
How many hours passed as you waited for the flirty message you sent got a green “read” tick? How anxious did you feel as you thumb hovered before you read their non-committal reply?
Pause for a moment before you blithely create more data: what if you decided to create less instead? Or figured out what it is that you already create, and what the value in it could be?
There is an argument that says tracking yourself and creating as much data as possible is a big step to fully owning your life.
It’s not a revolutionary statement: mindfulness meditation means allowing unwelcome thoughts to happen and facing them head on, so what if you did the same with your unwelcome data too? Would you focus on the good data?
How would you recognise it, anyway?
Everything, everything
Collating everything means you get a huge, zoomed-out view of your life - and if you can figure out how to use this data, you can tweak your life into a series of slightly better versions of itself.
And fret not - you are already doused by a firehose of data, generated by your own actions, every day.
Example A: Here’s a simple, life-improving data-collection experiment that your doctor may have already asked you to undertake.
“I’m anxious,” you tell the doctor, “and I’m overworked, and I can’t sleep. I need to be less anxious, sleep better, and be more happy. Help.”
Idly tapping her pen against her knuckles, the doctor asks, “How much coffee do you drink a day?” And you immediately scoff: you need real help, not to keep tabs on your beverages!
But still, you dutifully track your mood throughout each day by marking it out of ten (hey, it’s often a 5, hmm), and record how many cups of coffee you gulp down.
It turns out that you swill a lot of the black stuff: big, strong espressos to wake you up, another long sugary coffee for the commute, and, well, the office does have that endless filter machine in the corner, just an office-chair-shove away - the one with the fresh-ground-locally-roasted beans…
So you compare the two, and slash your coffee habit to see if you are calmer as a result. And you are. And you sleep better. Simple. Why didn’t you think of this yourself?
Small, workable changes are hard to spot when you’re creating them. But when you integrate this data with new technology, you can start to integrate these changes with your world in a pleasant way.
And then you can use this data and make it play a fortune-telling role in your life.
Example B: And now, here’s a simple way that you could use tech that exists right now to make tiny acts of magic happen in your life.
Does the rain make you measurably sadder? What could you do to simply make life better, easier, more calming? What could happen automagically?
Let’s say that every couple of hours, your Apple Watch asks you to record your mood. And then this data, along with weather alert data, your geo-location, and your calendar, is automatically fed into a service like IFFT.
You then also dutifully connect your home’s internet-connected lightbulbs, wifi-enabled coffee machine, your phone, and your Google Home speaker as well.
Wait, wait, bear with me. This might sound a lot like building weird life-LEGO, but it’s the crux of your quantified future: lots and lots of seemingly unconnected data splicing in simple ways to subtly change your life for the better.
Data variables in, effects on your life out
Now consider the emotion sausage-machine you have built.

In a hyper-connected tomorrow, things will take a turn for the better before you even have a chance to contemplate the grumbling. Here’s how.
IFFT can see from your GPS data and your diary that you’re at home but about to leave for a meeting. It also hears via the National Weather service that it’s about to rain heavily, and notices from your self-collected mood data that you’re already hovering around a middling-to-gloomy 6.5 today.
So it quietly triggers some pre-emptive actions. Your favourite music fades up, the lights bloom into a calming pink, your favourite (decaff!) coffee steams and froths away in the corner of the kitchen, and a subtly worded notification reminds that it’s time to go - and you really should grab your umbrella before you leave.
Before you’ve even been able to let a bad mood take hold, you’ve built a system that gently steers you - literally - into calmer waters.
And this is a fairly trivial example. You could set this up in an afternoon. There's now limitless opportunities to remix your life-data in ways that are perfect for you. Finally, you’ve got something better to do with all that fitness wearables data than try and run around the park a bit faster.
Go back to the top of this article: how happy were you then? How much happier would you be if life was just that little bit simpler? Now you just need to figure out how connected you're willing to be in order to get it.

问题描述 :
After listening several songs of Jinkeloid,I come up with this problem :).
There is a string s only consist of first 20 lowercase English letters.
And we have several queries,each time I have k letters c1, c2, …, ck,and I wonder how many consecutive substring of string s that each ci has occur even times in it.
Two substring with the same content but different position are considered different.

盯着CLJ那神奇的两行代码看了半天啊，最近我的智商真心让我感到蛋蛋的忧伤，，，，，
各位出题人能不能不要在题解上加上任何带情感色彩的词语啊啊啊啊啊。。。
比如，“简单的dp”。。。。。。研究了一下午，，，233333333
说到这个题，其实可以通过预处理之后，对于每个询问，用容斥来做，或者像标称那样暴力，枚举一个集合的母集，然后减掉。题解都说的很清楚了，我就不多说什么了，毕竟是别人的思路。。。。
就贴一贴那段神奇的“简单的dp”，你能看出两个循环后cnt数组变成了什么吗？？反正我是折腾了半天（还是得从dp的角度去理解），一步步模拟只能知其然啊。。。
其实思想类似与倍增的DP，我觉得这道题最精髓的就是下面这个了，，，
for(int j = 0; j < 20; j++) { for(int i = 0; i < 1<<20; i++) if(i>>j&1) { cnt[i^(1<<j)] += cnt[i]; } }

Photography
In an era that everyone who holds a camera will be called a photographer, photography has more and more enthusiasts. Every day we can enjoy millions of photos scattered on social media, especially on Instagram. Beautiful images from people who choose photography as a hobby, to spectacular works from a professional photographer in different styles or genres of photography. Starting from architectural, candid, documentary, fashion, food, landscape, night-long exposure, photojournalism, portraiture, sport, street, wildlife, aerial to fine art photography. From black and white to color, photography remains a beautiful work for its lovers.
Since I love photography, I appreciate every moment of my life and my surroundings more. Moments when I travel, meet friends, and vacation with family—I capture every moment that will be a beautiful memory to remember. I also pay more attention to the moment around me, natural moments like sunrises, sunsets, fog, and rain. I also like to capture more moments of people's lives, especially for moments that can't be repeated like moments of cultural events and the moment of the cremation ceremony in Bali.
Photography makes me think of more creative concepts and rich ideas. It's an image that has a visual appeal and can be understood even without words. How to make photos that can attract readers, touch their hearts and minds to support my writing as a writer, so I have to understand photography—although I didn't ever take formal photography lessons.

Spanish police seize 'drugs submarine' off coast of Galicia
by EuronewsPolice in Spain have detained two people after intercepting a submarine suspected of carrying drugs, according to police sources.
The submarine, which was intercepted off the coast of Galicia on Sunday, was believed to be carrying around 3,000 kilograms of cocaine, news agency EFE quoted Spain’s Guardia Civil as saying.
But a central government source told Reuters the narcotics cargo had not yet been confirmed.
Two South American men have since been detained in a joint Guardia Civil and National Police operation, and a third man has escaped, according to the same source.
An operation to surface the vessel is set to resume later on Monday.

Ether |
(gas) |
Finding the ether reports on Erowid a bit disappointing, I wanted to share a bit of my own experience. My employment gives me access to unlimited amounts of reagent grade diethyl ether. It is powerful stuff! Taking (inhaling) it at baseline is the most fun. One first feels a powerful head rush, yet this is only the beginning of the magic. I guess the best way to describe it is that you see ghosts.
I remember one night sitting on my couch and seeing a couple walk out of my kitchen, go into my bedroom, and start making out. Another time I was in my lab and saw a face appear on the side of a five gallon bucket- he burped at me- lol! I've done ether a few times after drinking . . . bad idea. I passed out for good. Another aspect of ether is that it truly is addictive. So, what's this dawg's bottom opinion on ether . . .? I think it is an amazing time if done cautiously and when sober. But as always be careful.
Experience Reports are the writings and opinions of the individual authors who submit them.
Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.
