The CMSIS-SVD format is based on XML and was influenced by IP-XACT. Due to the much wider scope and complexity of IP-XACT, it was decided to specify a separate format focused and tailored towards the description of the programmer's view of a device.
CMSIS-SVD XML Hierarchy
CMSIS-SVD Hierarchy Levels
One CMSIS-SVD file contains the description of a single device. A device consists of a processor and at least one peripheral. Each peripheral contains at least one register. A register may consist of one or more fields. The range of values for a field may be further described with enumerated values.
- File Conventions: Outlines the main conventions for writing an SVD description file.
- SVD File Example Provides an example outlining the SVD XML structure.
- Device Level: The top level of a System View Description is the device. On this level, information is captured that is specific to the device as a whole. For example, the device name, description, or version. The minimal addressable unit as well as the bit-width of the data bus are required by the debugger to perform the correct target accesses.
Default values for register attributes like register size, reset value, and access permissions can be set for the whole device on this level and are implicitly inherited by the lower levels of the description. If however specified on a lower level, the default setting from a higher level will get overruled.
- CPU Level: The CPU section describes the processor included in the microcontroller device. This section is mandatory if the SVD file is used to generate the device header file.
- Peripherals Level: A peripheral is a named collection of registers. A peripheral is mapped to a defined base address within the device's address space. A peripheral allocates one or more exclusive address blocks relative to its base address, such that all described registers fit into the allocated address blocks. Allocated addresses without an associated register description are automatically considered reserved. The peripheral can be assigned to a group of peripherals and may be associated with one or more interrupts.
- Registers Level: A register is a named, programmable resource that belongs to a peripheral. Registers are mapped to a defined address in the address space of the device. An address is specified relative to the peripheral base address. The description of a register documents the purpose and function of the resource. A debugger requires information about the permitted access to a resource as well as side effects triggered by read and write accesses respectively.
- Fields Level: Registers may be partitioned into chunks of bits of distinct functionality. A chunk is referred to as field. The field names within a single register must be unique. Only architecturally defined fields shall be described. Any bits not being explicitly described are treated as reserved. They are not displayed in the System Viewer and are padded in the bit fields of the device header file. The case-insensitive field named "reserved" is treated as a keyword and each field with this name is ignored.
- Enumerated Values Level: An enumeration maps an unsigned integer constant to a descriptive identifier and, optionally, to a description string. Enumerations are used in C to enhance the readability of source code. Similarly, it can be used by debuggers to provide more instructive information to the programmer, avoiding a lookup in the device documentation.
- Special Elements: Specific elements that occur in various other elements are described in this section.
- Vendor Extensions: The CMSIS-SVD format includes a section named <vendorExtensions> positioned after the closing tag </peripherals>. This allows silicon vendors and tool partners to extend the description beyond the current specification.
Multiple Instantiation
CMSIS-SVD supports the reuse of whole sections of the description. The attribute derivedFrom for peripheral, register, and field specifies the source of the section to be copied from. Individual tags can be used to redefine specific elements within a copied section.
Array of Elements
A powerfull construct in data structures of the C programming language is the array. An array is a series of data elements of the same type selected via an index. CMSIS-SVD supports arrays for peripheral, cluster, and register.
Peripheral Grouping
Peripherals that provide similar functionality (Simple Timer, Complex Timer) can be grouped with the element <groupName>. Peripheral groups help structuring the list of peripherals in the debugger. All peripherals associated with the same group name are collectively listed under this group in the order they were specified in the SVD file.
Descriptions
On each level, the tag <description> provides verbose information about the respective element. The description field plays an important part in improving software development productivity as it gives instant access to information that otherwise would need to be looked up in the device documentation.
All multiple whitespace characters (space, tab, linefeed, carriage return) may be removed from the description by any tool for further processing (i.e. SVDConv does). In order to preserve explicit linebreaks one has to use the linefeed escape sequence (i.e. \n).

This project includes data from the city of Columbus, OH and APIs for accessing that information. Our goal is to make this data available and help build interest and knowledge about what is possible with city-level data.
Looking to the future, we hope to see this kind of data being put to better use and encouraging both city officials and citizens alike to think about their city in a more data-centric way. We hope that this project can not only be of use to those interested in learning more about the city of Columbus but also to those looking for new way to think about city planning, technology, and the future we are all building together.
The following examples use the above API and illustrate some of the possibilities for using this data:

Welcome to my website
Today I am going to give you information about different dogs and which breed is ideal pet for you
There are many breeds of dog. Each breed has its own common characters. When you come to
choose your breed you need to consider some of the characters each breed has such as:
- They shed
- They have alot of energy
- They are very smart
Considering all the factors,
here are some of breeds we recommend:


Class.forName("org.fit.proxy.jdbc.ProxyDriver");
Connection proxyConnection = DriverManager.getConnection("jdbc:proxy:../properties/proxy.properties");
----
import org.fit.proxy.jdbc.ProxyDriver;
...
DriverManager.registerDriver(new ProxyDriver());
Connection proxyConnection = DriverManager.getConnection("jdbc:proxy:../properties/proxy.properties");
There is also a possibility to get a connection with given properties only without URL:
import org.fit.proxy.jdbc.ProxyDriver;
...
Properties proxyProperties = new Properties();
proxyProperties.load("../properties/proxy.properties");
Driver proxyDriver = new ProxyDriver();
Connection proxyConnection = proxyDriver(null, proxyProperties);
When URL and Properties are given, properties file given by URL is selected
import org.fit.proxy.jdbc.ProxyDriver;
...
Properties proxyProperties = new Properties();
proxyProperties.load("../properties/anotherProxy.properties");
Driver proxyDriver = new ProxyDriver();
Connection proxyConnection = proxyDriver("jdbc:proxy:../properties/selectedProxy.properties", proxyProperties);
If no URL and Properties are given, it tries to search for properties in current directory with name: config.properties
import org.fit.proxy.jdbc.ProxyDriver;
...
Driver proxyDriver = new ProxyDriver();
Connection proxyConnection = proxyDriver(null, null); //URL is same as "jdbc:proxy:./config.properties"
It is not allowed to have two database connections with the same name.
items=2
db0_driver=com.mysql.jdbc.Driver
db0_url=jdbc:mysql://localhost/proxyDatabase1
db0_name=MyDatabase1
db0_user=proxyDriver1
db0_password=heslo1
db0_regexp=^UPDATE*
db1_driver=com.mysql.jdbc.Driver
db1_url=jdbc:mysql://localhost/proxyDatabase2?user=proxyDriver2&password=heslo2
db1_name=MyDatabase2
db1_regexp=^SELECT*
default=MyDatabase2
Using driver is very simple, use it like standard JDBC driver. Suppose that properties settings are same in following examples as they are in previous and data are the same in both databases.
//open connection
Class.forName("org.fit.proxy.jdbc.ProxyDriver");
Connection proxyConnection = DriverManager.getConnection("jdbc:proxy:../properties/proxy.properties");
Statement proxyStatement = proxyConnection.createStatement();
//update data in first database
proxyStatement.execute("UPDATE `persons` SET firstName = 'Lazy' WHERE ID = 8");
//print data from second database
ResultSet rs = proxyStatement.executeQuery("SELECT * FROM `persons`");
while (rs.next()) {
System.out.println(rs.getString(1) + "," + rs.getString(2) + "," + rs.getString(3));
}
//setting auto commit = false
proxyConnection.setAutoCommit(false);
proxyStatement.executeQuery("UPDATE persons SET `homeID` = 2 WHERE `homeID` = 1"); //updates MyDatabase1
proxyStatement.executeQuery("INSERT INTO `homes` (`street`, `city`, `houseNumber`, `zipCode`) VALUES ('Svobodná', 'Svobodov', '1', '1')"); //updates MyDatabase2 (is default)
//rollback
proxyConnection.rollback();
//New feature - setting default connection
ProxyConnection proxy = (ProxyConnection) proxyConnection;
//setting connection which is not present - will fail
try {
proxy.setDefaultConnection("Nonsense");
} catch (SQLException e) {
System.err.println(e.getMessage()); //will be printed
}
//setting default connection correctly
proxy.setDefaultConnection("MyDatabase1");
proxyStatement.executeQuery("INSERT INTO `homes` (`street`, `city`, `houseNumber`, `zipCode`) VALUES ('Svobodná', 'Svobodov', '1', '1')"); //updates MyDatabase1 (is default)
//unset default connection
proxy.unsetDefaultConnection();
//Trying to execute queries that are not associated - an exception will be thrown
try {
proxyStatement.executeQuery("INSERT INTO `homes` (`street`, `city`, `houseNumber`, `zipCode`) VALUES ('Svobodná', 'Svobodov', '1', '1')"); //will fail - query is not associated to any database connection
} catch (SQLException e) {
System.err.println(e.getMessage()); //will be printed
}
//close connection
proxyStatement.close();
proxyConnection.close();
The only thing that is set on start is auto commit = true and read only = false. Setting of one thing will affect all connection. Furthermore, asking for value of connection attribute will probably fail if called before setting. However, this won't happen when you do this thing in a statement.
Class.forName("org.fit.proxy.jdbc.ProxyDriver");
Connection proxyConnection = DriverManager.getConnection("jdbc:proxy:../properties/proxy.properties");
boolean readOnly = proxyConnection.isReadOnly(); //will fail
proxyConnection.setReadOnly(true); //will not be executed
Class.forName("org.fit.proxy.jdbc.ProxyDriver");
Connection proxyConnection = DriverManager.getConnection("jdbc:proxy:../properties/proxy.properties");
proxyConnection.setReadOnly(true);
boolean readOnly = proxyConnection.isReadOnly(); //correct
Other advices concerns transactions. Do not use them unless you are absolutely sure what you are doing! Make sure that all what you are doing in transactions is supported by all JDBC drivers.
These methods are all unsupported. Using them will throw an UnsupportedOperationException. All of them are contained in ProxyConnection class.

Test method names should clearly indicate what they are testing.
A test’s purpose (what is being tested, any pre-conditions, and the expected result) should be obvious from its name alone. It should not be necessary to read the code to work out what is being tested.
The general naming convention for a test class and its fixtures is:
public class <ClassNameUnderTest>Tests { // separated by underscores [Test] public void <SystemUnderTest>_<PostCondition>() {...} // or [Test] public void <SystemUnderTest>_<PreCondition>_<PostCondition>() {...} }
For unit tests, the SystemUnderTest
will usually be the name of the method you are testing.
[Test] public void HazardLightsTest() {...}
[Test] public void HazardLightsToggleButton_WhenPushedWithLightsBlinking_StopsLightsBlinking() {...}
If you are having difficultly naming your test this way, it might indicate it is doing too much and should be split into more granular tests.


Concentric Program Notes
This is a program to create concentric rings of polygons, and to allow you to decorate them in the Islamic style. See the paper “Beyond the Great 96” presented at the 2021 Bridges program.
The program is quite self-explanatory. Just push buttons and slide sliders. We start from the left and add columns of tiles to build up a tiling that we will wrap around a central ring.
Here’s an example to get you started:
Slide the N slider to 10. (After clicking, you can also use the left and right arrow buttons to do small adjustments.)
Hit these column buttons in order:
Then the mode button:
This should give you a copy of our logo’s design:
When I want to start a new tiling, I reload the page.
It may help to first choose what how many sides you want in your center n-gon by sliding the N slider.
Column Buttons
The column buttons change type depending on the shape of the edge that needs to be matched. Certain columns fit best with small n. Certain fit best with larger n. Experiment. You can always undo. Some buttons force you to use an even number for n.
The column buttons are grouped by the Left/Right turns that you make traveling along the left edge. You start with the pattern going Straight, with no turns. The left edges will fit against the current tiling. The right edges will be the new outside of the tiling. Here are all the column buttons.
When it comes time to fit in a new column, look at the ring area. You can see how big the angles you need are. The program will squeeze in whatever you tell it to, but the closer the angles, the better the fit, and the nicer the tiling may look.
Depending on the columns you choose, the edge lengths may grow or shrink. It's traditional to try to keep the edge lengths as constant as you can. If you want to decrease the edge length, try finding buttons that have more segments on the right side, or that have a wider angle on the left side. If you want to increase the edge length, find buttons that keep the same number of segments on the right side and use smaller angles on the left side.
If you hover over a button, it will tell you what it does. The column buttons tell you what size the right edge is. This size is given in the list of all column buttons. In general, we want to slowly decrease the size until we reach .5 which is where we usually double the number of sides and restart. Restarting is shown in the list by “x 2”. There are some shapes that go a little below .5. These shapes would work best with a large n. With a small n, we have to get to .5 faster.
For a given tiling, you might try changing the N slider to make the edge lengths match for the inner and the outer edges. This can't do anything for the in-between parts.
Mode Buttons
The mode buttons tell how the tiling is decorated. I prefer to run in base tiling mode so I can see the shapes of the tiles. You can also run in star or rosette mode, if you like.
Here is the same tiling in all three modes.
In star mode, an extra slider appears. You can play with the angle if you want. One cool thing that I only noticed after I made the program is that if you use star mode, very small angles and very large angles look similar – but with the colors reversed. So very small angles give you pointy purple stars and a white background. Very large angles give you pointy white stars and a purple background. Here’s a different tiling in star mode with very small and very large angles.
Saving
You can download PNG image files or SVG files of either the stack or the ring with the save buttons.
More examples
Set n = 6. Then use this button:
to get this:
Note that this button doubles the numbers of edges in one step – so it works best with very small n.
Or set n=15.
Then use these four column buttons:
to get this:
These are both examples of small n.
Here’s an example of large n – the example given in the paper.
Set n = 184.
Choose these buttons:
then
to get this big image
Play with it. Have fun.

Pladipus or bringing cluster management to the masses
- 1. Development
- 2. Requirements
- 3. Contact
1. Development
Pladipus was originally developed at the CompOmics group at Ghent University, Belgium (part of VIB) as
part of a pipeline for large scale reprocessing of public proteomics data from the PRIDE database.
Since the initial developments, Pladipus has been enhanced to have many capabilities
which can be applied to many computationally intense problems that can be "embarrassingly parallelised".
Since the initial prototype, Pladipus has become a true cluster management system and has been continuously operated
at the CompOmics group.
Examples of applied usages for the Pladipus Framework applications include:
- Extraction of both precursor and fragment ion mass accuracies for all projects in PRIDE
- Generation of a database of theoretical peptides using MS2PIP
- Reprocessing of all human projects in PRIDE against UniProtKB
2. Requirements
- Access to a MySQL-server
- Access to an ActiveMQ
- A central repository to store results/input data
Pladipus is under continuous development at the CompOmics lab.

These release notes cover new developer and user-facing incompatibilities, features, and major improvements.
Direct Bytebuffer decompressors for Zlib (Deflate & Gzip) and Snappy
The 'du' (disk usage command from Unix) script refresh monitor is now configurable in the same way as its 'df' counterpart, via the property 'fs.du.interval', the default of which is 10 minute (in ms).
Added file system implementation for OpenStack Swift. There are two implementation: block and native (similar to Amazon S3 integration). Data locality issue solved by patch in Swift, commit procedure to OpenStack is in progress.
To use implementation add to core-site.xml following:
xml <property> <name>fs.swift.impl</name> <value>com.mirantis.fs.SwiftFileSystem</value> </property> <property> <name>fs.swift.block.impl</name> <value>com.mirantis.fs.block.SwiftBlockFileSystem</value> </property>
In MapReduce job specify following configs for OpenStack Keystone authentication:
java conf.set("swift.auth.url", "http://<IP_ADDRESS>:5000/v2.0/tokens"); conf.set("swift.tenant", "superuser"); conf.set("swift.username", "admin1"); conf.set("swift.password", "password"); conf.setInt("swift.http.port", 8080); conf.setInt("swift.https.port", 443);
Additional information specified on github: https://github.com/DmitryMezhensky/Hadoop-and-Swift-integration
Add a new editlog record (OP_ADD_BLOCK) that only records allocation of the new block instead of the entire block list, on every block allocation.
Makes the retries and time between retries getting the length of the last block on file configurable. Below are the new configurations.
dfs.client.retry.times.get-last-block-length dfs.client.retry.interval-ms.get-last-block-length
They are set to the 3 and 4000 respectively, these being what was previously hardcoded.
Add new HTTP policy configuration. Users can use "dfs.http.policy" to control the HTTP endpoints for NameNode and DataNode. Specifically, The following values are supported: - HTTP_ONLY : Service is provided only on http - HTTPS_ONLY : Service is provided only on https - HTTP_AND_HTTPS : Service is provided both on http and https
hadoop.ssl.enabled and dfs.https.enabled are deprecated. When the deprecated configuration properties are still configured, currently http policy is decided based on the following rules: 1. If dfs.http.policy is set to HTTPS_ONLY or HTTP_AND_HTTPS. It picks the specified policy, otherwise it proceeds to 2~4. 2. It picks HTTPS_ONLY if hadoop.ssl.enabled equals to true. 3. It picks HTTP_AND_HTTPS if dfs.https.enable equals to true. 4. It picks HTTP_ONLY for other configurations.
Fix the https support in HsftpFileSystem. With the change the client now verifies the server certificate. In particular, client side will verify the Common Name of the certificate using a strategy specified by the configuration property "hadoop.ssl.hostname.verifier".
libhdfs now returns correct codes in errno. Previously, due to a bug, many functions set errno to 255 instead of the more specific error code.
Add a new configuration property "dfs.webhdfs.user.provider.user.pattern" for specifying user name filters for WebHDFS.
Addition of FixedLengthInputFormat and FixedLengthRecordReader in the org.apache.hadoop.mapreduce.lib.input package. These two classes can be used when you need to read data from files containing fixed length (fixed width) records. Such files have no CR/LF (or any combination thereof), no delimiters etc, but each record is a fixed length, and extra data is padded with spaces. The data is one gigantic line within a file. When creating a job that specifies this input format, the job must have the "mapreduce.input.fixedlengthinputformat.record.length" property set as follows myJobConf.setInt("mapreduce.input.fixedlengthinputformat.record.length",[myFixedRecordLength]);
Please see javadoc for more details.


The U.S. Census and You!
Making Choropleths from Census Data
Everyone living in the U.S. in a "residental structure" is counted, regardless of citizenship.
(Americans living abroad aren't counted...unless they work for the Federal Government.)
Here's what a dotmap of that looks like...
What questions are on the Census?
This 2010 Census was one of the shortest in the history of the U.S. Census. It consisted of only 10 questions.
In 1940, there were 50 questions.
Important Information about Census Data
Census data is only available as aggregate data.
(Unless it's over 72 years old or you have access to a Federal Research Data Center)
Census data is broken down into a series of increasingly smaller units
- state
- county
- tract
- block group
- block
Every census unit has a numeric geographic identifier (GEOID)
Not all Census tracts are equal
- Tracts are drawn by population, not geographic area.
- Population density can result in a wide range of tract sizes.
- The goal is to have between 1,200 and 8,000 residents in a tract, with 4,000 being the ideal.
Census units are redrawn for every Decennial Census
- People move, so tract boundaries are changed to maintain population size.
- Really important when trying to compare Census findings from one year to another.
Where do you get U.S. Census data?
Finding the data you want
- Use the Download Center if you know what tables you need or you want prepackaged data
- Use Advanced Search if you need to explore the data more
- Use the Help option if you want to become a data ninja
TIGER
Topologically Integrated Geographic Encoding and Referencing
This is the clearinghouse for all of the U.S. Census Bureau's mapping products. Mapping products are available as shapefiles, geodatabases, and kmls.
Downloading county data from TIGER
- Go to the TIGER web interface
- Choose the year you want data for and then select "Counties (and Equivalent)" as the datatype
- On the next page, select the state or opt to download all the states in one file
- Click the download button and select where you want to save the file
Want data for a specific place but don't know it's GEOID?
Try TIGERweb
Getting Started with QGIS
Adding TIGER data to QGIS
- Click Add Vector Layer
- Use the Browse button to find your saved shapefile
- Click on the Open button
Adding Fact Finder data to QGIS
- Click Add Delimited Text Layer
- Use the Browse button to find your saved csv file
- Make sure the radio buttons for "CSV" and "No geometry" are selected
- Click OK
Finding your keys
In a GIS, primary and foreign keys are used to join layers together. A primary key is a unique identifier for each record that has no duplicate values and is not null. A foreign key, matches the primary key, but is located in a different table. In Census data, we use the GEOID for both keys.
You'll need to know which column in each of your data layers contains the GEOID. You can do this by right-clicking on a data layer and selecting Open Attribute Table. You'll then be able to scroll through the data and find the column is the one you want.
Performing a table join
- Right-click on the vector layer
- Select Properties and then the Joins tab
- Click on the green plus symbol
- In the pop-up menu, the Join Layer is the table layer you want to join, the Join Field is the foreign key, and the Target Field is the primary key
- Click Okay
- Open the attribute table and check that the join worked
Troubleshooting
- If your table join isn't working, first make sure that you're selecting the correct fields for your primary and foreign keys.
- If the columns are correct and it's still not working, check the Fields tab under the layer Properties to make sure the data types of the two columns are the same.
- If the column data types are different, you'll need a sidecar file to correct the problem.
Normalizing the Data
- Select the layer you want to normalize
- Open the Field Calculator
- Create a new field and name it
- Set the new field's field type, as well as the precision and width
- In the expression editor, write an expression that divides the data your want to normalize by a field containing population data
- Click Ok
Categorizing the Data
- Open the layer properties and select the Style tab
- Select Graduated from the upper left dropdown menu
- Use the Column dropdown menu to select your normalized field
- Select the Mode of classification you're going to use
- Click the Classify button in the middle of the screen to add your classes
- Click Ok
Choosing a Classification Scheme
The classification scheme you choose makes a big difference to how your map represents the data.
John Krygier breaks this down on his website.
Selecting a Color Scheme
Once again, John Krygier has this covered.
Using Colorbrewer in QGIS
- From the Settings menu, select Style Manager
- Choose the Color Ramp option and click Add
- In the dropdown menu, select ColorBrewer
- From here you can select any of the color schemes available on ColorBrewer
- Click Ok to choose your color scheme and then give it a name
- The next time you go to set a layer Style, you shoudl see the new color ramp as an option
*You can also make these changes in the Layer Properties Style tab*

Allegiant adding five new nonstop routes, three to Nashville, two to Florida
by Dawn Gilbertson, USA TODAYAllegiant Air is adding five new nonstop routes in February: three to Nashville and two to Florida.
On Tuesday, the Las Vegas-based discount carrier, which offers bargain fares but charges extra for everything else – including advance seat assignments, carry on bags and soft drinks, said the new seasonal routes are aimed at spring break and summer vacationers.
Allegiant doesn't offer daily service on its routes like major airlines, generally offering flights one, two or three times a week depending on the route and demand. The new routes, which will all be offered twice a week:
Nashville International Airport, to and from:

Case study
TripBuzz is the example of startup which has been developed over the last few years by our team.
The app makes sightseeing across States easier categorizing the attractions according to the distance and activity type.
Our role
The service grows organically, it started from MVP and is based on LEAN approach.
Our role so far has been to choose the best tools, design software architecture, implement both backened and frontend, adjust it to changes the owners wanted to introduce, suggest best technical solutions for each new idea, monitor the app running with huge traffic.
History
-
2015
We created background workers which helped with processing big amounts of geo data.
New feature for adding user feedback to sightseeing attractions was developed. -
2014
Voting system for attractions, thematic pages templates, hotel search functionality were added.
We introduced individual attraction pages and mobile version of thematic pages. -
2013
We designed software architecture and implemented the first version of TripBuzz.
Technology
TripBuzz relies on geographical data and uses them to a great extent. The algorithm has been implemented to connect data from the rating system with geo data. This allowed us to provide the best attractions for the given location in the search results.
A sophisticated caching system has been implemented to maintain speed of the search engine with the growing userbase. In order to build the cache we've developed a set of background workers which update the cached data continuously.
Similar projects
From an idea to new versions
We have worked with startup founders since 2010. We've been wearing different hats in the process of development.


Front Proxy¶
To get a flavor of what Envoy has to offer as a front proxy, we are releasing a docker compose
sandbox that deploys a front Envoy and a couple of services (simple Flask apps) colocated with a
running service Envoy. The three containers will be deployed inside a virtual network called
envoymesh
.
Below you can see a graphic showing the docker compose deployment:
All incoming requests are routed via the front Envoy, which is acting as a reverse proxy sitting on
the edge of the envoymesh
network. Port 8080
, 8443
, and 8001
are exposed by docker
compose (see /examples/front-proxy/docker-compose.yaml) to handle HTTP
, HTTPS
calls
to the services and requests to /admin
respectively. Moreover, notice that all traffic routed
by the front Envoy to the service containers is actually routed to the service Envoys
(routes setup in /examples/front-proxy/front-envoy.yaml). In turn the service Envoys route
the request to the Flask app via the loopback address (routes setup in /examples/front-proxy/service-envoy.yaml).
This setup illustrates the advantage of running service Envoys collocated with your services: all
requests are handled by the service Envoy, and efficiently routed to your services.
Running the Sandbox¶
The following documentation runs through the setup of an Envoy cluster organized as is described in the image above.
Step 1: Install Docker
Ensure that you have a recent versions of docker
and docker-compose
installed.
A simple way to achieve this is via the Docker Desktop.
Step 2: Clone the Envoy repo, and start all of our containers
If you have not cloned the Envoy repo, clone it with git clone git@github.com:envoyproxy/envoy
or git clone https://github.com/envoyproxy/envoy.git
:
$ pwd
envoy/examples/front-proxy
$ docker-compose build --pull
$ docker-compose up -d
$ docker-compose ps
Name Command State Ports
------------------------------------------------------------------------------------------------------------------------------------------------------

front-proxy_service2_1 /bin/sh -c /usr/local/bin/ ... Up 10000/tcp, 8000/tcp
Step 3: Test Envoy’s routing capabilities
You can now send a request to both services via the front-envoy
.
For service1
:
$ curl -v localhost:8080/service/1

Notice that each request, while sent to the front Envoy, was correctly routed to the respective application.
We can also use HTTPS
to call services behind the front Envoy. For example, calling service1
:
$ curl https://localhost:8443/service/1 -k -v
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8443 (#0)

Step 4: Test Envoy’s load balancing capabilities
Now let’s scale up our service1
nodes to demonstrate the load balancing abilities of Envoy:
$ docker-compose scale service1=3
Creating and starting example_service1_2 ... done
Creating and starting example_service1_3 ... done
Now if we send a request to service1
multiple times, the front Envoy will load balance the
requests by doing a round robin of the three service1
machines:
$ curl -v localhost:8080/service/1
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)

< x-envoy-protocol-version: HTTP/1.1
<
Hello from behind Envoy (service 1)! hostname: 36418bc3c824 resolvedhostname: <IP_ADDRESS>
Step 5: enter containers and curl services
In addition of using curl
from your host machine, you can also enter the
containers themselves and curl
from inside them. To enter a container you
can use docker-compose exec <container_name> /bin/bash
. For example we can
enter the front-envoy
container, and curl
for services locally:
$ docker-compose exec front-envoy /bin/bash
root@81288499f9d7:/# curl localhost:8080/service/1
Hello from behind Envoy (service 1)! hostname: 85ac151715c6 resolvedhostname: <IP_ADDRESS>
root@81288499f9d7:/# curl localhost:8080/service/1
Hello from behind Envoy (service 1)! hostname: 20da22cfc955 resolvedhostname: <IP_ADDRESS>
root@81288499f9d7:/# curl localhost:8080/service/1
Hello from behind Envoy (service 1)! hostname: f26027f1ce28 resolvedhostname: <IP_ADDRESS>
root@81288499f9d7:/# curl localhost:8080/service/2
Hello from behind Envoy (service 2)! hostname: 92f4a3737bbc resolvedhostname: <IP_ADDRESS>
Step 6: enter containers and curl admin
When Envoy runs it also attaches an admin
to your desired port. In the example
configs the admin is bound to port 8001
. We can curl
it to gain useful information.
For example you can curl
/server_info
to get information about the
Envoy version you are running. Additionally you can curl
/stats
to get
statistics. For example inside front-envoy
we can get:
$ docker-compose exec front-envoy /bin/bash
root@e654c2c83277:/# curl localhost:8001/server_info

Hello There!
My name is Jonathan Thomas.
I am a recent Computer Engineering graduate from the University of Florida and am currently looking for a full time position.
I have experience with core programming fundamentals and some web development as well.
Below I have attached links to my Linkedin and GitHub accounts as well as my Resume.


What prevents an application, like Twitter, Â of acquiring more and more users besides the geek users? Even within my circle of friends and acquaintances that work/study with IT, when I talk about I’ m a Twitter user, I need to repeat uncountable times what Twitter is about Â and I usually explain to them according to what twitter advertise as their goal (Not a micro blogging tool, What are you doing?). In 90% of the cases, they say they heard about it but don’t know whatÂ´s its purpose, in other words, they donÂ´t know how they could use twitter for their benefit.Â ”Why would I tell Â´followersÂ´ what I am doing ?Â¨ is the most asked question after Â my explanation.Â Â It means TwitterÂ´s initial goal failed to instigate the user to create a new need, but why ?

As seen in the graph, thereÂ´s Â a steep Â that divides Early adopter users from the mainstream users. I believe that this gap,Â Â which is always Â the final “test” to any application to become popular, is becoming even steeper between Â theÂ Early Adopter user (the ones who adopt new technologies before the vast majority of people) and the mainstream user due the fact Â most of the services around the web, like twitter, Â being targeted (mostly due to bad advertisement) to Early Adopters users. Like I said before, it happens that forÂ mainstream users the reason for what they would use something needs to be clearly written in giant letters with neon lights otherwise they wonÂ´t buy Â your idea by just “giving a try”.
I myself, being an early adopter user, believe we are living in some kind of technological bubble and even though we see so many applications doing success around there, most of them are not even close of what they could reach because they are kept restricted to the geek world. There’s a lot of things that could be achieved. In my opinion, before saturating the market with thousands of applications that Â deliver the same product in different designs, we could stop being so selfish and besides developing applications we should care about how we are going to sell our idea and how to create the need inside the userÂ´s mind.
However, create focusing the real need of the final user isn’ t a easy task. We, developers, having the bad habit of programming to ourselves, solving our own problems and satisfying our selfish needs doesnÂ´t help much either. Because of that, we live in this technological bubble where we create services/products to impress our friends with all our freak techniques and for what ? Just to be to be used by ourselves. But how to break the bubble ? How to identify the needs of the mainstream users ? It’s really hard to give final answers to these questions, however, I believe the solution is start paying attention to our non-geek friends (if you donÂ´t have non-geek friends, can be your mom) Â in their day-to-day and trying to assume the mainstream user’s role.Â
Users donÂ´t like to take risk. They are very different from people like me and probably you. They donÂ´t care about 99% of the things we care about, Â so pay attention to the people around you, notice how they interact with the computer as well their reactions behind it. One user screwing his face in front of the computer can be the best time to ask him to find out what’ s wrong and how he think it might be possible to improve.

An opensouce library that brings database features into your JavaScript applications.
How you ever noticed how JavaScript object literals look a lot like records? And that if you wrap a group of them up in an array you have something that looks a lot like a database table? TaffyDB is a libary to bring powerful database funtionality to that concept and rapidly improve the way you work with data inside of JavaScript.
// Create DB and fill it with records var friends = TAFFY([ {"id":1,"gender":"M","first":"John","last":"Smith","city":"Seattle, WA","status":"Active"}, {"id":2,"gender":"F","first":"Kelly","last":"Ruth","city":"Dallas, TX","status":"Active"}, {"id":3,"gender":"M","first":"Jeff","last":"Stevenson","city":"Washington, D.C.","status":"Active"}, {"id":4,"gender":"F","first":"Jennifer","last":"Gill","city":"Seattle, WA","status":"Active"} ]);
// Find all the friends in Seattle friends({city:"Seattle, WA"}); // Find John Smith, by ID friends({id:1}); // Find John Smith, by Name friends({first:"John",last:"Smith"});
// Kelly's record var kelly = friends({id:2}).first(); // Kelly's last name var kellyslastname = kelly.last; // Get an array of record ids var cities = friends().select("id"); // Get an array of distinct cities var cities = friends().distinct("city"); // Apply a function to all the male friends friends({gender:"M"}).each(function (r) { alert(r.name + "!"); });
// Move John Smith to Las Vegas friends({first:"John",last:"Smith"}).update({city:"Las Vegas, NV:"}); // Remove Jennifer Gill as a friend friends({id:4}).remove(); // insert a new friend friends.insert({"id":5,"gender":"F","first":"Jennifer","last":"Gill","city":"Seattle, WA","status":"Active"});


Managing Category Menu Settings
How to manage the category menu settings of the Store module.
- Go to the Store Menu module.
-
- Select the Category Menu Settings tab.
- At Display Mode, select from these options:
- Table: Displays categories inside an HTML table. Customers must click on a parent category to view any child categories. This is the default settings.
- List: Displays all categories on the page at the same time. Child categories are indented below their parent categories. This option allows web designers use jQuery or Java.
- In the Column Count text box, enter the number of columns to use when displaying categories. In the below example, a column count of two ( 2 ) is used.
- At Catalog Page, select the page where the Store Catalog module is located. Typically this will be Same Page, which is the default setting. You may however prefer to have two Store Menus for your store. E.g. You may have one Store Menu module on the Home page of your site that drives people to your store. In this case, you would set Store Menu module on the Home page to direct to the page name of your Store.

Perform any special initialization steps.
The earlyInitHook_() function must be implemented by the derived class as a static function.
These functions run before the C Run-time setup functions are called, and normal functionality (e.g. OS concepts) are not available.
Early initialization steps represent any super early code that needs to execute. For example, DRAM might need to be initialized before the boot process can relocate memory to its proper location in memory.
These functions are declared static to prevent you from easily using drivers within their confines

The hard_reset_() function must be implemented by the derived class.
A hard reset is intended to perform a full power cycle of the system.

The initProcessor_() function must be implemented by the derived class.
Perform any steps necessary for initializing the processor & processor peripheral devices for use.
Note that this is only intended to be processor initialization. Platform initialization nis handled by the init() function.
This function will likely invoke the VirtualProcessor::init() function, but the order and actual initialization process is left to the derived class.

Shutdown the system.
The shutdown_() function must be implemented by the derived class.
If your platform supports shutdown capability, take the proper steps to initiate a shutdown.
If the platform does not support shutdown capability, implement your shutdown_() function as an assert to notify users trying to call this API. You could also leave the shutdown_() function undefined. Anyone who calls the shutdown() function on a platform with an undefined shutdown_() function will encounter a compiler error.
The shutdown function is not expected to return.
◆ soft_reset()
Perform a soft reset of the system (chip reset)
The soft_reset_() function must be implemnted by the derived class.
A soft reset is intended to reset the program to the beginning without performing a full power cycle.
A good strategy is to just call virtual processor's reset() function, if one is provided.

Schneier on Security: Marcus Ranum's "The Six Dumbest Ideas in Computer Security"
Link from Bruce Schneir's blog to an article by Marcus Ranum. As always some interesting thoughts, this time about the dumbest ideas in security, some of which I agree with and some which I'm not so sure about.
The 1st, default permit I'd agree with. Default Permit is all over IT. One example which I think is interesting but not mentioned is URL filtering. Any company I've seen run a default permit and blacklist concept for web traffic filtering. Whilst I can see why that would work from a usability perspective, it's next to useless from a security standpoint. As soon as you allow access to unknown sites, you're allowing access to everything as users can use one of the variety of tunnelling or proxying programs to get access to all the content you've blocked, as can any virii or worms that might get installed..
Enumerating badness, yeah, I like it in principle, although I do think that Marcus is understating the level of complexity in enumerating the goodness. Sure there may be only 20-30 programs you use in an interactive sense, there are many more pieces of code executed that you're not aware of...
Penetrate and Patch. This is a well made point, in that code should be designed to be secure, as should systems. However I'm not convinced of the wortlessness of penetration testing. Once you've designed your secure system and implemented it, shouldn't someone test that it actually is secure?
Number four's a bit of a "yeah but no" point. Yeah hacking isn't cool (in the criminal sense of hacking) but understanding how you're current adversary operates, is to my mind, useful.....
Number Five... nah ain't buying it. The implication of this point is that user education has done nothing for security, because there are still some users who don't behave securely... so should we not take any countermeasures unless they're going to be 100% successful!? User education has done a lot for security it's just, like all other countermeasuers not perfect...
Number Six, I'll go along with, the number of people who seem ready to jump on the latest security bandwagon, whilst still not doing the fundamentals of good security operations well never ceases to amaze me...
All interesting stuff though and well worth a read...


History
- Originally developed by Jack Slocum.
- Started as extension to Yahoo's YUI! framework.
- Interactive Data Grid
- Ext JS 1.0 was released two years ago from tomorrow, April 15th 2007.
- Has adapters for jQuery, Prototype and YUI.
- Abstracted the implementation of its base library.
- 2.0 introduced components/containers/layouts
- Migrating from Ext JS 1.x to Ext JS 2.x involved some major architecture changes.
- Ext Core (subset of Ext JS)
- Ext JS 2.x was a solid foundation to build Ext 3.0 on and there are almost no breaking changes.
- 3.0 Ext Direct, DataWriters, Accessibility (ARIA) and much more.


I am a full stack developer. I 💚 all things technology.
I've been developing for a number of years. It's cool...I like it a lot.
It's great! Just be careful not to overdo it. I used to put tabasco on everything. I also like Texas Pete hot sauce, and Herdez Guacamole Salsa. I've never tried ghost peppers, and don't think I'm really interested.

The Foreign Function Interface (FFI) is a mechanism for interfacing Slogan with C libraries.
Slogan has two interfaces for communicating with C libraries. First we will discuss the higher-level interface made available through
the declare ffi
statement.
syntax: declare ffi library_name list_of_prototypes
`library_name` should be a string or an identifier. If it is a string, it must be the full or
relative path of the C library to be loaded. If the path is relative, the library is first looked
up in the local folder and then under the paths specified in the `LD_LIBRARY_PATH`
environment variable.
If `library_name` is an identifier it must point to a library object loaded by the
`ffi_open` function, described later in this chapter.
`list_of_prototypes contain prototype declarations of functions and structures in the C library.
The Slogan compiler uses these declarations to define functions that act as proxies to
access C objects.
A function prototype has the following syntax:
syntax: return_type c_function_name list_of_argument_types as proxy_function_name
`proxy_function_name` is optional. If provided, the Slogan function that acts as a proxy will be
bound to this name. Otherwise it will be bound to `c_function_name`.
The following table list type names that can be used in a prototype and their equivalent C-types:
Type Equivalent C-type
==== =================
uint8 uint8_t
int8 int8_t
uint16 uint16_t
int16 int16_t
uint32 uint32_t
int32 int32_t
uchar unsigned char
char signed char
ushort unsigned short
short signed short
uint unsigned int
int signed int
ulong unsigned long
long signed long
uint64 uint64_t
int64 int64_t
float float
double double
longdouble long double
charstring char *
pointer void *
void void
Note that the void type can only be used as a return type. It cannot be used as the
type of a parameter.
As an example, two C functions and their corresponding prototypes are given below:
// sample_c_lib.c
#include <math.h>
double square_root(double f) { return sqrt(f); }
long add_li(int i, long l) { return ((long)i) + l; }
// end of sample_c_lib.c
// importing this library from slogan:
declare ffi "sample_c_lib.so" [double square_root [double] as sqrt,
long add_li [int, long]];
This prototype declaration means that the Slogan program can call the C `square_root`
function as `sqrt(param)` and the `add_li` function with the same name.
A structure prototype has the following syntax:
syntax: struct c_struct_name list_of_members
`list_of_members` is an association list of the types and field names.
For example consider the definition of a C struct and its corresponding prototype:
// sample_c_lib.c
struct point {
int x;
int y;
};
struct point make_point(int x, int y)
{
struct point p = {x, y};
return p;
}
// end of C code.
// importing the struct in Slogan:
declare ffi "sample_c_lib.so" [struct point [int:x, int:y],
point make_point [int, int]];
Note that a struct prototype is required only if Slogan has to call C functions
that deal with struct instances directly, i.e not through pointers.
If all C functions that you need to call deal with pointers to structures,
you can get by with function declarations with the pointer type.
Struct prototypes are also required if you want to inspect the contents of a
pointer to a structure or you want to construct an instance of the structure from Slogan.
The complete example is reproduced below:
// sample_c_lib.c
#include <math.h>
double square_root(double f) { return sqrt(f); }
long add_li(int i, long l) { return ((long)i) + l; }
// end of sample_c_lib.c
// sample_c_lib.c
struct point {
int x;
int y;
};
struct point make_point(int x, int y)
{
struct point p = {x, y};
return p;
}
// end of C code.
// Compile to a shared library (Linux):
$ gcc -Wall -shared -fPIC -o sample_c_lib.so sample_c_lib.c
// Compile to a shared library (OS X):
$ gcc -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -o sample_c_lib.so sample_c_lib.c
// Loading and using the C library from Slogan:
declare ffi "c_lib.so" [double square_root [double] as sqrt,
long add_li [int, long],
struct point [int:x, int:y],
point make_point [int, int]];
sqrt(10.3);
//=> 3.2093613071762426
add_li(10, 20);
//=> 30
let p = make_point(100, 200);
c_struct_name(p);
//=> point
c_struct_get(p, 'x);
//=> 100
c_struct_get(p, 'y);
//=> 200
function: c_struct_name(s)
returns: a symbol which is the name of the C-struct instance `s`.
function: c_struct_get(s, m)
returns: the value of the member `m` from the structure `s`, false if the member is not found.
function: c_struct_instance(n, v)
returns: a new instance of the structure named `n` with the members initialized to the values of the list `v`.
The values list should be specified in the same order as the members in the struct definition.
function: pointer_to_c_struct(n, ptr)
returns: casts the generic pointer `ptr` to a pointer to the structure named `n`.
The header file src/include/slogan.h
define certain constants that control the number of arguments that can be passed to
a C function and the number of C-struct proxies that can be defined in Slogan. These definitions are:
#define SLOGAN_LIBFFI_ARGC 32
#define SLOGAN_LIBFFI_STRUCT_DEFS 32
#define SLOGAN_LIBFFI_STRUCT_SIZE 1024
By default the number of arguments and struct proxies are limited at 32
. A struct can be up to 1024
bytes in size.
These limits can be increased or decreased as per the applications requirement. Slogan must be rebuilt for these changes to take effect.
The lower-level FFI gives more control over making C function calls. It also allows C functions to callback into Slogan code.
A C function to be callable from low-level FFI must have one of the following signatures:
Here args
is an array of ___slogan_obj
objects. Argp
is a pointer to an arbitrary C object and the return_type
is one of: void
, void*
, ___slogan_obj
, char
, char*
, int
, unsigned int
, long
, unsigned long
, long long
, float
or double
.
The type ___slogan_obj
represent all Slogan objects like strings, lists, integers and characters.
The header file slogan.h
declare functions and macros required for converting a ___slogan_obj
to a
C object and vice versa.
This section describes the C macros and functions defined in slogan.h
for converting between ___slogan_obj
and C types.
C macro: ___slogan_obj_to_char(s, t)
C macro: ___slogan_obj_to_uchar(s, t)
C macro: ___slogan_obj_to_int(s, t)
C macro: ___slogan_obj_to_uint(s, t)
C macro: ___slogan_obj_to_long(s, t)
C macro: ___slogan_obj_to_ulong(s, t)
C macro: ___slogan_obj_to_longlong(s, t)
C macro: ___slogan_obj_to_float(s, t)
C macro: ___slogan_obj_to_double(s, t)
C macro: ___slogan_obj_to_charstring(s, t)
C macro: ___slogan_obj_to_nonnull_charstring(s, t)
C macro: ___slogan_obj_to_void_pointer(s, t)
The ___slogan_obj object `s` is converted to a C int, unsigned int, float, double or
char* and stored in `t` which should be the address of a C variable of the appropriate type.
C macro: ___int(s)
returns: a C int that contain the integer value of the Slogan character or integer
(___slogan_obj) `s`.
C function: ___slogan_obj ___fix(int i)
returns: a ___slogan_obj containing the value of the C integer `i`.
C macro: ___char_to_slogan_obj(c)
returns: a ___slogan_obj containing the value of the character `c`.
C macro: ___uchar_to_slogan_obj(c)
returns: a ___slogan_obj containing the value of the unsigned character `c`.
C macro: ___uint_to_slogan_obj(i)
returns: a ___slogan_obj containing the value of the unsigned integer `i`.
C macro: ___ulong_to_slogan_obj(i)
returns: a ___slogan_obj containing the value of the unsigned long `i`.
C macro: ___long_to_slogan_obj(i)
returns: a ___slogan_obj representing the long value `i`.
C macro: ___longlong_to_slogan_obj(i)
returns: a ___slogan_obj representing the long long value `i`.
C macro: ___float_to_slogan_obj(f)
returns: a ___slogan_obj representing the float value `f`.
C macro: ___double_to_slogan_obj(d)
returns: a ___slogan_obj representing the double value `d`.
C macro: ___void_pointer_to_slogan_obj(p)
returns: a ___slogan_obj representing the generic pointer `p`.
C macro: ___charstring_to_slogan_obj(c, s)
C macro: ___nonnullcharstring_to_slogan_obj(c, s)
___charstring_to_slogan_obj initializes the ___slogan_obj `s` as a Slogan string with
the characters from the C string `c`. ___charstring_to_slogan_obj creates a
null-terminated string and ___nonnullcharstring_to_slogan_obj creates a string object
that keeps track of its length. The C string `c` should always be null terminated.
The following C code shows the correct way to use these functions:
// test.c
#include <stdio.h>
#include "slogan.h"
___slogan_obj hi(___slogan_obj *args)
{
___slogan_obj message;
char *s = "hi from C!";
char *p;
___slogan_obj_to_charstring(args[0], &p);
printf("Slogan says \"%s\"\n", p);
___charstring_to_slogan_obj(s, &message);
return message;
}
// end of test.c
This can be compiled to a shared library on Linux using the command:
$ gcc -Wall -shared -fPIC -I ${SLOGAN_HOME}/src/include/ \
-I ${SLOGAN_HOME}/platform/gsc/include -o test.so test.c
and on OS X using this command:
$ gcc -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -I \
${SLOGAN_HOME}/src/include/ -I ${SLOGAN_HOME}/platform/gsc/include -o test.so test.c
The function `hi` can be invoked from Slogan as shown below:
let clib = ffi_open("./test.so");
let f = ffi_fn(clib, "hi");
ffi_call_obj(f, #["hello from Slogan"]);
//-> Slogan says "hello from Slogan"
//=> hi from C!
ffi_close(clib);
//=> true
C function: ___slogan_obj ___pair(___slogan_obj obj1, ___slogan_obj obj2)
returns: a ___slogan_obj that represents a Slogan pair with head and tail pointing to
`obj1` and `obj2`.
Both `obj1` and `obj2` must be of types ___slogan_obj.
C macro: ___head(p)
C macro: ___tail(p)
returns: the head or tail objects of the ___slogan_obj `p` that represents a Slogan pair.
C constant: ___TRU
C constant: ___FAL
returns: the ___slogan_obj that represents the Slogan values true or false.
C constant: ___NUL
returns: the ___slogan_obj that represents the empty list [].
C macro: ___is_empty(pair)
returns: ___TRU if pair is the empty list [], ___FAL otherwise.
The following C function demonstrates how to receive a list of integers from Slogan and print it:
void print_i_list(___slogan_obj *args)
{
___slogan_obj a = args[0];
while (!___is_empty(a)) {
___slogan_obj h = ___head(a);
___slogan_obj t = ___tail(a);
int i;
___slogan_obj_to_int(h, &i);
printf("%d\n", i);
a = t;
}
}
`print_i_list` can be invoked from Slogan as shown below:
let f = ffi_fn(clib, "print_i_list");
ffi_call_void(f, #[[1, 10, -3, 99]]);
//-> 1
10
-3
99
C macro: ___body(array)
returns: a C array of ___slogan_obj objects that are the elements of the Slogan array array.
The following C function prints the first two elements of a Slogan array passed to it. The function
expects the first element to be an integer and the second element to be a string.
void f(___slogan_obj *args)
{
___slogan_obj *b = ___body(args[0]);
int i;
char *s;
___slogan_obj_to_int(b[0], &i);
___slogan_obj_to_charstring(b[1], &s);
printf("%d\n%s\n", i, s);
}
This function can be invoked from Slogan as:
f = ffi_fn(clib, "f");
ffi_call_void(f, #[#[100, "hello"]]);
//-> 100
hello
A bunch of macros and functions are provided for working with arrays. (Some of the macros require the local variable
`___slogan_obj ___temp;`
to be declared explicitly.)
C function: ___slogan_obj ___alloc_u8array(int size)
returns: a byte array of length `size`.
C function: ___slogan_obj ___alloc_array(int size)
returns: an array of length `size`.
C macro: ___array_length(array)
returns: the number of elements in `array` as a C integer.
C macro: ___array_at(array, i)
returns: the element in `array` at index `i` as a ___slogan_obj.
C macro: ___array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
The index argument must be passed in as a Slogan integer (i.e ___fix(i)
).
Equivalent macros are available for arrays of signed/unsigned integers and floats. Similar macros are there to access and manipulate Slogan strings as well:
C macro: ___s8array_length(array)

C macro: ___u16array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
C macro: ___s32array_length(array)
returns: the number of elements in `array` as a C integer.
C macro: ___s32array_at(array, i)
returns: the element in `array` at index `i` as a ___slogan_obj.
C macro: ___s32array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
C macro: ___u32array_length(array)

C macro: ___u64array_length(array)
returns: the number of elements in `array` as a C integer.
C macro: ___u64array_at(array, i)
returns: the element in `array` at index `i` as a ___slogan_obj.
C macro: ___u64array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
C macro: ___f32array_length(array)
returns: the number of elements in `array` as a C integer.
C macro: ___f32array_at(array, i)
returns: the element in `array` at index `i` as a ___slogan_obj.
C macro: ___f32array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
C macro: ___f64array_length(array)
returns: the number of elements in `array` as a C integer.
C macro: ___f64array_at(array, i)
returns: the element in `array` at index `i` as a ___slogan_obj.
C macro: ___f64array_set(array, i, obj)
returns: sets the element in `array` at index `i` to the ___slogan_obj `obj`.
C macro: ___string_length(s)
returns: the number of characters in the string `s` as a C integer.
C macro: ___string_at(s, i)
returns: the character in `s` at index `i` as a ___slogan_obj.
C macro: ___string_set(s, i, obj)
returns: sets the character in `s` at index `i` to the ___slogan_obj `obj`.
function: ffi_open(libname)
returns: an object representing a "handle" to the shared library file named `libname`, false
if the shared library could not be loaded.
function: ffi_close(lib_handle)
returns: true if the shared library represented by `lib_handle` was successfully unloaded,
false otherwise.
function: ffi_fn(lib_handle, fnname)
returns: returns the address of the function named `fnname` from the library represented
by `lib_handle`, false if the function is not found.
The functions described below are used for calling a C function. `fn_pointer` is the function pointer returned by `ffi_fn`. `args` must be an array and `argp` must be a pointer to a C object.
The ___call_fn
function enables C code to call any function implemented in Slogan. ___call_fn
takes two arguments - the function object to call and its arguments. The arguments are passed as a single list. ___call_fn
will return a ___slogan_obj
which is the return value of the Slogan function. The following example show how to write a shared library that makes a call back into Slogan:
/* call_fn_test.c */
#include <stdio.h>
#include "slogan.h"
___slogan_obj call(___slogan_obj *args)
{
int error = 0;
___slogan_obj result;
___slogan_obj f = args[0];
___ON_THROW(result = ___call_fn(f, ___pair(___fix(100), ___pair(___fix(200), ___NUL))), error = 1);
if (error == 1)
{
printf("Slogan function raised error\n");
return ___FAL;
}
return result;
}
The ___ON_THROW
macro will set the integer variable error
to 1
if the Slogan function raised an exception.
Once the C file is compiled into a shared library, call
can be invoked as shown below:
let clib = ffi_open("./call_fn_test.so");
let f = ffi_fn(clib, "call");
ffi_call_obj(f, #[add]);
//=> 300

CL-MEMCACHED is a Simple, Fast, Thread-Safe library to interface with the memcached object caching system. It implements the Memcached TEXT protocol.
Tested on SBCL, CCL, CMUCL.
memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
Danga Interactive developed memcached to enhance the speed of LiveJournal.com, a site which was already doing 20 million+ dynamic page views per day for 1 million users with a bunch of webservers and a bunch of database servers. memcached dropped the database load to almost nothing, yielding faster page load times for users, better resource utilization, and faster access to the databases on a memcache miss.
The code comes with a MIT-style license so you can basically do with it whatever you want.

| Dalli on Ruby 1.9 | 0.957 | 1.033 |
When we do not use the pool we make a new socket connection every time.
The Ruby 'dalli' client, which implements the binary protocol, uses the same socket (I think) so this should be comparable with our with-pool.

San Pedro & P. harmala (Syrian Rue)
10:15PM - Pick friend up from work.
10:30PM - Each ingested 1 capsule of harmala extract, containing the extract of about 1 tablespoon of harmala seeds.
11:00PM - Each of us drink Green Slime Tea giving each of us a dose equal to about ~65g of dried Pedro.
11:30PM - I get hit by INTENSE nausea and run to the bathroom. I vomit, then go back to the couch feeling miserable. My mind is full of negative thoughts, something that's never happened from Pedro before and which I feel came from the harmala. I spend the next hour or so fighting off waves of nausea, having to run to vomit about 5 ot 6 times.  Unlike the nausea harmala normally induces, rather than feeling as if I am dying, after the first puke I feel as if I am purging myself of negative emotions. Every heave throws out another bad feeling, leaving me feeling cleansed when all of it is over.
12:00AM - OH MY GOD!!! The trip has reached very intense levels. Keeping my
eyes open becomes difficult because so much is going on internally. Recent
life events are being reviewed from many points of view simultaneously,
interspersed with bizarre visuals, such as a universe in which nothing exists but millions of smurfs running around in a black vacuum. When I open my eyes, the room is very strange - shadows are meaningful entities, perspectives alter instantanously, everything is weird.
12:00AM thru 6:00AM - After the nausea passes, I am in a very good mood, though all I can do is lay on the couch and alternate between watching open-eye visuals and closing my eyes to reflect on things and watch closed-eye visuals. The closed eye visuals are weird... in one, a man is sitting in a bathtub taking a bath, only the bathtub is floating in the middle of a vast ocean. In another, I am watching a formal party, with people in tuxedos and evening gowns - only they are in a swimming pool with water up to their necks - this seems to be where they want to be, however. I am able to examine recent events in my life in amazingly clear detail, free from my own anxieties.
The television is on the whole time, and whenever I open my eyes and look at it, there is a different show on, it seems. It's impossible to follow the plots of anything I see for more than 20 or 30 seconds, though this could be due to the fact that I dont feel like watching. The shadows on the walls are much more interesting visual stimuli. At some point, I close my eyes and have a very intense closed eye visual.
I see a San Pedro in front of me, very realistic. All of the sudden, it grows to enormous size - hundreds of branches going out in every direction. The branches are easily 2 feet in diameter, and 40 or 50 feet tall. This mega-cactus is strangely alive, and seems to move slightly. All of the sudden the face of an old man appears on the top of the main branch of the cactus, and its eyes look down to its 'belly', which swells then opens up,revealing a large sphere of stars - I realize I am looking at the universe. A voice tells me that this is inside me as well, and that what needs to be done is to take this core of my being and pour out its energy in the form of love. The voice asks me if I understand and I answer that I do - and the vision ends.
I open my eyes and sit up, and tell my friends that I have just seen God. We all laugh. Laughter is a dominant emotion all night - I say emotion, because it is laughter for no reason other than just being alive. We keep commenting on how everything is weird - and derive great joy from the inherent oddness of the universe.
6:00AM-12:00PM: Several people who had been at a club all night come over, and everyone does a round of 1,4-butanediol. I took 2.5ml, then about an hour later take 3ml. A strange thing happens - my body becomes extremely intoxicated from the BDO, but my mind remains in a mescaline state, seemingly untouched by the BDO. This incongruity leaves me with the strange and not quite comfortable feeling that I am unable to control my body. While my coordination is shot, my mind is clear. I'm completely unable to sleep, though my body is very tired. Not a combination I'd ever try again. Finally, around 10AM, a friend drives me home where I finally manage to fall asleep around noon. I wake up exhausted but
spiritually refreshed.

Bayelsa has shown willingness to change destiny - Lokpobiri
by https://www.facebook.com/CheerfulpraiseMike Odiegwu, Yenagoa
Former Minister of State for Agriculture and Rural Development, Senator Heineken Lokpobiri has commended the people of Bayelsa State for changing their destiny by voting the All Progressives Congress (APC) in the Saturday election.
Lokpobiri said the victory of the APC was a loud and clear message from Bayelsans that they were ready and willing to ensure prosperity and good governance.
He congratulated Bayelsans and urged them to believe in the party because the APC would move the state to the next level with a renewed and amicable partnership with the Federal government led by President Muhammadu Buhari.

He said such partnership would help the state attain the desired visible and sustainable development in the State.
Lokpobiri further commended Buhari, the APC governors, especially Governors of Kebbi and Jigawa States, and the National Leadership of the Party, for the victory of the party at the poll.

Development
This project utilized many different APIs: Synaptics Touchpad, Google Cloud Vision, and Wolfram Alpha. The program grabbed input from the touchpad as a multidimensional array, and saved an image of it. It then sent the image to Google Cloud Vision, which then used its massive neural network for image recognition to try to figure out what the numbers and symbols were. It created a string for the equation, which was then sent through Wolfram Alpha's API. Wolfram Alpha calculated the string, and return a large dictionary of data. The program sifted through the data to get the direct answer, and displays it. That is essentially what this project does and how it does it.
The first phase of the project is the touchpad. We hit some roadblocks with utilizing the touchpad early on. We had trouble getting input data from the touchpad, unless we pushed on the touchpad really hard. We eventually had the touchpad replaced, and found that our previous one was defective. You still had to press firmly on the touchpad, but it was much more natural now. We used the code given to us by Synaptic to grab the data, and then used that data to create an image.
After the image was created, we sent that image through Google Cloud Vision's API via a custom wrapper we wrote. This part was our biggest headache. When we tested the equation detecting from Google Cloud Vision, we found that most of the time, it does not correctly detect the equation. When we put in 3 * 2 into the touchpad, we sometimes get weird responses. We initially thought that it was again the touchpad, but later realized that the neural network may not be optimized for numbers and equations (plus, our hand-writing was a bit poor). We wanted it to be able to detect complex equations like derivatives and integrals, but realized that it was simply out of our scope and capabilities at the moment (fun fact: some integrals did end up working). Once the neural network gave a response, we sent it to Wolfram Alpha.
Wolfram Alpha computed the equation and gave us all sorts of data. We looked specifically for just the answer, and displayed it.
The UI was made using pygame, and it displayed what the touchpad captured, what the image looked like, what Google Cloud Vision thought the image was, and what Wolfram Alpha though the answer was.
