Welcome to FIWARE OFNIC GE’s documentation!¶
Refer to this page for more general information about OFNIC.
Installation & Administration¶
Goal of the document¶
The OFNIC is an implementation of the NetIC Generic Enabler Open Specifications. This GEi is in charge of providing a common programmable interface to an Openflow Network, by collecting information and statistics regarding the managed Openflow network node’s. This interface is based on the NetIC Open API RESTful specifications. The OFNIC GEi is an extension of the open-source OpenDaylight Controller. It relies on the Openflow protocol to retrieve network information about the managed network. The OFNIC GEi provides also a Graphical User Interface (GUI) based on web technologies. Basically this is a web page with javascript code that communicates with the RESTful interface of the GEi.
Goal of this document is to provide a useful guide for the installation of OFNIC GEi, together with its GUI. The document starts describing basic software and hardware required to support the OFNIC GEi on top of a device. It then follows with specific technical information that might help users and administrators: running processes, diagnosis tests, network flows etc.
OFNIC GEi¶
Software and Hardware environment¶
The OFNIC OpenFlow controller runs in a Java Virtual Machine. Being a Java application, it can (potentially) runs on any machine that supports Java. However, all the software have been tested on recent Linux distributions, so we recommend the following:
- A recent Linux distribution (for example Ubuntu 14.04 LTS or Debian 7.x)
- Java Virtual Machine 1.7
Prerequisites¶
- As the previous paragraph, being a Java application, the only requistite is Java Virtual Machine.
Getting OFNIC¶
There are two options for obtaining the OFNIC Controller. The first option is to download the pre-built current build. The second option is to getting the source code of the component and build the code on your machine.
The pre-built package can be downloaded at TBD
Another way of getting the source code is to pull the code by cloning the controller repository on GitHub with the following commands:
Build the code¶
Prerequisites¶
The following are required for building the codebase:
- Maven 3.x.y
If you use a Debian or Ubuntu machine, you can install Maven with the following command:
sudo apt-get install maven
and check the installed version with:
mvn -v
Using a system shell locate in the main OFNIC source code directory, where is located the pom.xml maven’s configuration file. Run the following commands:
mvn clean install
Running¶
Now OFNIC GEi is ready to start running. With a terminal locate in the main folder with the following content:
- opendaylight build folder
- ofnic.conf
- ofnic-uniroma1.jar
- qos_queue.con
- run.sh
- The command reported below starts the OFNIC controller:
- ./run.sh
Sanity check procedures¶
The Sanity Check Procedures are the steps that a System Administrator will take to verify that an installation is ready to be tested. This is therefore a preliminary set of tests to ensure that obvious or basic malfunctioning is fixed before proceeding to unit tests, integration tests and user validation.
End to End testing¶
This is basically quick testing to check that everything is up and running.
Launch ofnic with the command:
./run.sh
To verify that the OFNIC GEi is loaded correctly it should display bootstrap complete in the terminal on which it was launched.
Network nodes side, on ovs switch give the following command to verify that the device is correctly connected with the controller :
ovs-vsctl show
it should display the following log message:
- Bridge “br0”
- Controller “tcp:<IP_ADDRESS>” is_connected: true
- Port “br0”
- Interface “br0” type: internal
After this two checks have been done, the GEi should be up and ready. To test that is actually running a simple check can be done from the browser. Going with a normal internet browser application to the following address:
should display the list of all API of OFNIC GEi.
List of Running Processes¶
In order to list running processes on a Linux distribution one can use ps aux command. In order to get more filtered results one can use this more articulated command:
ps aux | grep “Name_of_process”
In the machine that hosts the OFNIC GEi the run.sh process is required to be active. So by typing in the terminal:
ps aux | grep run.sh
Network interfaces Up & Open¶
The OFNIC GEi listens to the ports 6633, 2222 and 8080, with the following command you can verify it:
netstat -lnptu | grep tcp
in the terminal you will see a list of the process listen on port 6633, 8080 and 2222.
Diagnosis Procedures¶
OFNIC logs to the stdout on the terminal on which it was launched.
Resource availability¶
The required RAM depends on many factors such as network topology, number of flows in the network, frequency of the statistics updates, frequency of web service requests, etc.
- Generally RAM size varies from 100 MB to 250 MB.
- Usually the disk size required during run time is negligible.
Remote Service Access¶
User can verify the correct execution of the OFNIC, by directing the browser (all types are supported) to the following page:
which should display a list of commands that can be sent to the interface. Note that if the browser app is not on the same machine of the GE, the remote IP address of the GEi can be used.
Resource consumption¶
The resource consumption is highly dependent on the number of network events processed. The minimum amount of RAM is nearly 200 MB so eventually in any lower amount of RAM means that the application did not load properly. Under normal working conditions RAM size reaches the order of 250 MB so values of greater orders mean that there is some malfunctioning. CPU percentage ranges and is highly dependent on the processor speed. However it should be noted that at idle state the OFNIC processor consumption can be even lower that 0.1%.
I/O flows¶
Port 2222 for RESTful API and port 6633 for the communication with the network nodes via OpenFlow plugin..

I drag around my MacBook Pro to different networks every day.
Sometimes, there are hassles connecting to a network, wired or wifi.
This little script can be used to kick the network interfaces a little bit to potentially fix strange states they find themselves in:

Dear Friend My name is Mr. David Kofi, the regional manager of International commercial Bank (ICB) Kaneshie Branch Ghana. I am a Ghanaian married with two kids. I have packaged a financial transaction that will benefit both of us. As the regional manager of the bank, it’s my duty to send financial reports to my head office in the capital city of Accra. On the course of the last year 2005 end of the of the year’s report, I discovered that my branch in which I am the manager made Six Million Five Hundred and Fifty Thousand US Dollars (6,550.000.00) of which my head Office is not aware of and will never be aware of. I have since then PLACED this fund on a SUSPENCE ACCOUNT without a beneficiary. As an officer of the bank, I cannot be directly connected to this money thus I am compelled to request for your assistance to receive this money into your bank account. I intend to part with 30% of this fund to you while 70% shall be for me. I do need to assure you that there is practically no risk involved in this. It’s going to be a bank-to-bank transfer. All I need from you is to stand as the original depositor of this fund. If you accept this offer, I will appreciate your timely response.

One of my favorite features of Editorial when I used it was the ability to open its internal web browser, find a website, and insert a link into the editor. This saved me so much time, and I wanted to recreate it in Drafts. This feature wasn’t possible in the exact same way, but I managed to make something that works well for me.
You can get the script from the Drafts Action Directory.
There’s a lot happening in it, but essentially when you run the action, you will be prompted to select a website you want to search and the term you want to search for. Drafts will then use DuckDuckGo’s URL parameters to search for the term you entered on the website you select. This is really handy if you have particular websites you like to reference. For instance, here I often link back to other posts I’ve written here.
To customize this, you just have to change what websites are entered in the sites object at the top. Replace the sites I have in there (like my own) with yours or another. Put the title to the left of the : (this is what will be displayed in the prompt) and the url (sans www.) to the right. If you’re not sure what any of that means, look at the script comments, and they should show you what to do.
I have also created on selection box that will search DuckDuckGo on the whole and one where you can enter a URL you haven’t already programmed in.
The final thing to notice is toward the bottom of the script.
Once I find the site or article I want to link to, I tap where the URL bar would be in normal Safari and hold. This will present you with a dialog to copy the URL to your clipboard.
var mdLink = Action.find("Markdown Link");
app.queueAction(mdLink, draft);
The little bit of JavaScript queues up the Markdown Link action which will turn the selected text in the Drafts editor into a Markdown link using a URL in your clipboard. These two actions tie together really well and make creating links to other articles super easy.
As someone who creates links in show notes and blog posts all the time, this is going to save me a ton of time, and I hope it does for you as well.

Since MTEX version 5.9 we use L2 normalized Wigner-D functions as basis functions for the harmonic series expansion of ODFs/SO3Funs.
Up to MTEX version 5.8 the ODFs has been definded by \[ F({\bf R}) = \sum \hat{f}_n^{k,l} \, D_n^{k,l}({\bf R})\] with \( D_n^{k,l}({\bf R}(\alpha,\beta,\gamma)) = \mathrm e^{-\mathrm i k\gamma} \mathrm d_n^{k,l}(\cos\beta) \,e^{-\mathrm i l\alpha} \). Hence the \(L_2\) norm of the Wigner-D function \(D_n^{k,l}\) was \(\sqrt{2n+1}\).
Now since MTEX version 5.9 the Wigner-D functions have \(L_2\) norm 1. Hence they are defined by \( D_n^{k,l}({\bf R}(\alpha,\beta,\gamma)) = \sqrt{2n+1} \, \mathrm e^{-\mathrm i k\gamma} \mathrm d_n^{k,l}(\cos\beta) \, e^{-\mathrm i l\alpha} \).
Take a look at Wigner-D functions.


(1) The handler does SQL operations (delete, select, and insert) on our plugin database.
(2) The handler queries for attributes or keys from the existing Zotero database since foreign key is not possible across databases.
(3) The AnyaPls plugin is wrapped into an XPI that serves as add-on for the existing Zotero source.
(4) On start-up of the plugin, the init creates the necessary tables, sets up required columns, and initialize objects.
(5) The XUL window contains user prompts and buttons that will trigger events in the field handlers.

ECDSA_SIG_new, ECDSA_SIG_free, ECDSA_SIG_get0, ECDSA_SIG_get0_r, ECDSA_SIG_get0_s, ECDSA_SIG_set0 - Functions for creating, destroying and manipulating ECDSA_SIG objects
#include <openssl/ecdsa.h>
ECDSA_SIG *ECDSA_SIG_new(void);
void ECDSA_SIG_free(ECDSA_SIG *sig);
void ECDSA_SIG_get0(const ECDSA_SIG *sig, const BIGNUM **pr, const BIGNUM **ps);
const BIGNUM *ECDSA_SIG_get0_r(const ECDSA_SIG *sig);
const BIGNUM *ECDSA_SIG_get0_s(const ECDSA_SIG *sig);
int ECDSA_SIG_set0(ECDSA_SIG *sig, BIGNUM *r, BIGNUM *s);
ECDSA_SIG is an opaque structure consisting of two BIGNUMs for the r and s value of an Elliptic Curve Digital Signature Algorithm (ECDSA) signature (see FIPS186-4 or X9.62). The ECDSA_SIG object was mainly used by the deprecated low level functions described in ECDSA_sign(3), it is still required in order to be able to set or get the values of r and s into or from a signature. This is mainly used for testing purposes as shown in the "EXAMPLES".
ECDSA_SIG_new() allocates an empty ECDSA_SIG structure. Note: before OpenSSL 1.1.0, the r and s components were initialised.
ECDSA_SIG_free() frees the ECDSA_SIG structure sig.
ECDSA_SIG_get0() returns internal pointers the r and s values contained in sig and stores them in *pr and *ps, respectively. The pointer pr or ps can be NULL, in which case the corresponding value is not returned.
The values r, s can also be retrieved separately by the corresponding function ECDSA_SIG_get0_r() and ECDSA_SIG_get0_s(), respectively.
Non-NULL r and s values can be set on the sig by calling ECDSA_SIG_set0(). Calling this function transfers the memory management of the values to the ECDSA_SIG object, and therefore the values that have been passed in should not be freed by the caller.
See i2d_ECDSA_SIG(3) and d2i_ECDSA_SIG(3) for information about encoding and decoding ECDSA signatures to/from DER.
ECDSA_SIG_new() returns NULL if the allocation fails.
ECDSA_SIG_set0() returns 1 on success or 0 on failure.
ECDSA_SIG_get0_r() and ECDSA_SIG_get0_s() return the corresponding value, or NULL if it is unset.
Extract signature r and s values from a ECDSA signature of size signaturelen:
ECDSA_SIG *obj;
const BIGNUM *r, *s;
/* Load a signature into the ECDSA_SIG object */
obj = d2i_ECDSA_SIG(NULL, &signature, signaturelen);
if (obj == NULL)
/* error */
r = ECDSA_SIG_get0_r(obj);
s = ECDSA_SIG_get0_s(obj);
if (r == NULL || s == NULL)
/* error */
/* Use BN_bn2binpad() here to convert to r and s into byte arrays */
/*
* Do not try to access I<r> or I<s> after calling ECDSA_SIG_free(),
* as they are both freed by this call.
*/
ECDSA_SIG_free(obj);
Convert r and s byte arrays into an ECDSA_SIG signature of size signaturelen:
ECDSA_SIG *obj = NULL;
unsigned char *signature = NULL;
size_t signaturelen;
BIGNUM *rbn = NULL, *sbn = NULL;
obj = ECDSA_SIG_new();
if (obj == NULL)
/* error */
rbn = BN_bin2bn(r, rlen, NULL);
sbn = BN_bin2bn(s, slen, NULL);
if (rbn == NULL || sbn == NULL)
/* error */
if (!ECDSA_SIG_set0(obj, rbn, sbn))
/* error */
/* Set these to NULL since they are now owned by obj */
rbn = sbn = NULL;
signaturelen = i2d_ECDSA_SIG(obj, &signature);
if (signaturelen <= 0)
/* error */
/*
* This signature could now be passed to L<EVP_DigestVerify(3)>
* or L<EVP_DigestVerifyFinal(3)>
*/

Icons
Naked CSS is Use Font Awesome
for Icon.
You can place the Icons just about anywhere using the CSS Prefix xn
and the icon's name. The Icons is designed to be used with inline elements (we like the <i>
tag for brevity, but using a <span>
is more semantically correct).
Basic Icons

I have this one sitting in my "To Blog" bookmarks list for ages now, so here it goes. It is actually inspired by a great post by Eric Ries entitled "A new version of the Joel Test". The original Joel Test was written in 2000 and Eric tried to update it a little bit based on his experience in software development in agile teams. Same as him I start with Joel’s list.

Do you use source control? Yes, essential and check.

Can you make a build in one step? We have continuous integration, so check.

Do you make daily builds? Well, building continuously would qualify I think. Ok, we could always do with more automated test but we are doing ok.

Do you have a bug database? Sure, check.

Do you fix bugs before writing code? There I am with Eric, yes we try to, but bug is not bug. There are some things we accept to fix later. But we do have an ASAP list that gets precendence over anything else.

Do you have an up-to-date schedule? Here I again agree with Eric, damn I agree aa lot with him, but that's the point. What we learned is that not the schedule is important, but keeping sprints short. As soon as a sprint goes over more than 2 weeks we have a problem of too big a backlog for the next one, too long testing, too much waiting, too hard to test features and the like. Our progress, which is what it is about, is better with shorter sprints, which take less planning and can actually be planned on the spot.

Do you have a spec? Eric rephrases that into "does the team have a clear objective?" Yes, this is what is important. We try to have a 1-3 sentence goal for each sprint. Everything is aligned to that. There are then cross functional teams that build the spec. In the first meeting we create scribbles, get the features down, try to make the interactions clear, and go from there. This first meeting is very important though and we have failed in this before because you need the cross functional team there and you need to discuss things to the end and fight it out and the team needs to stay fixed afterwards. This is sometimes hard, but very important.

Do programmers have quiet working conditions? It's not one size fits all. Two of our devs moved out of each others office because one likes to hear to music and one likes it quiet. Some want company, some don't. You need to enable that.

Do you use the best tools money can buy? We try to and this should probably be taking up a bit more, but hey, we are a startup that watches the money.

Do you have testers? Everybody writes tests first and then codes, as best possible. Yes, we have somebody responsible that makes sure everybody does that, but developer is developer. This is still to be decided in my mind. After a certain team size you probably need someone that takes care of the infrastructure, enabling automated testing by developers, and builds new test cases and handles the release process. But for small teams, it's a team responsibility.

Do new candidates write code during their interview? We didn't do that yet, but more or less knew the people we hired, so it wasn't so necessary. What we would be doing more in the future to give a new developer full responsibility for a new feature that is laid out so that it interacts with the entire platform. Then let everything be discussed in the weekly code review.

Do you do hallway usability testing? Majorly lacking here, sorry. We are trying to keep iterations short but will probably have to do some learning in this field.

 Next up are some of his suggestions. Yes, we do work in small batches and through daily scrums we know who is working on what and hence there are little conflicts at checking. He also talks about practicing the five Whys which I remember from the MBA. It’s a great idea. Why is it a great idea? Because it allows you to think up till the root cause? Why does that help? Because you don’t fix something that does not need fixing but what really went wrong. Why? Because after the first idea you ask why again and go on from there… get the point? 5 Whys. It’s a great system and oh so simple.
He then goes on to talk about the difference between defects and polish. This is very important to understand. We build a feature, often taking the easy way for the interface (after we learned building it complicated first is nuts ;)) and how it works but making sure there are no bugs, that it works, and does so reliably. From there we can build polish if need be. This is a subtle difference, but an important one.
His last point is probably the most important one: Does everyone (he names programmers but that’s not enough) understand how what they are doing relates to the company strategy, well being, vision, day to day business? This is where the cross functional teams help. It helps programmers understand what people do. A good developer will go nuts finding out that somebody sits there doing something in the interface for 2 hours every day when the dev can whip up something simple and get that down to 5 minutes. But you need to have communication.
That is actually one thing that I would like to add. The most important thing, and the reason for being of Agile, is that you have communication. The entire point of now doing waterfall development is that you know that the biggest problem in software development is that people speak different languages. Every party will need to try to work out what the other party really means. That is hard, and painful sometimes but only understanding will lead to good code.

IndexSQL language
(The symbols < and > means the parameter is optional)
CREATE TABLE
Syntax: “CREATE TABLE table_name (
column1 datatype <constraints>,
column2 datatype <constraints>,
....
PRIMARY KEY (columnName),
< FOREIGN KEY (columnName) REFERENCES
foreignTableName(foreignTableColumn)>
);”
It creates the table table_name . It will contain the columns, with the datatypes and constraints specified, the constraints are optional, and they are:
- NOT_NULL The column value won’t be null
- UNIQUE The column value won’t be repeated
- DEFAULT If the column value is not specified, it will be the default
- AUTO_INCREMENT If the column value is not specified, it will be the the next one, only available with datatype number.
The possible datatypes are:
- NUMBER
- STRING
- BOOLEAN
IndexSQL will accept other SQL datatypes like VARCHAR but it will assign them one of the primitive datatypes and it won’t check the length of the columns data.
The primary key is a column that will act as the key to the whole column. It will be NOT_NULL and UNIQUE by default.
The foreign keys will be a series of keys that are related to another column in another table. It means that during the insertion, it will check if the value of the column exists on the foreign table.
DROP TABLE
Syntax: “DROP TABLE table_name;”
It will delete the table_name table and all their values. This action cannot be reverted.
TRUNCATE TABLE
Syntax: “DROP TRUNCATE table_name;”
It will delete all the values of the table_name table and leave it clean. This action cannot be reverted.
TABLES
Syntax: “TABLES;”
It will return a list with all the tables of the system.
INSERT INTO
Syntax:” INSERT INTO table_name <(column1, column2, column3, ...)>
VALUES (value1, value2, value3, ...);”
It will insert the values into the table_name. The columns are optional, if they are not specified, it will take the values in the order the table was originally created.
If the columns contain the primary key, and the primary key matches any other primary key of the table. It will rewrite the contents.
SELECT
Syntax:”SELECT <DISTINCT> column1, column2, ... FROM table_name <WHERE condition> <ORDER BY column1 ASC|DESC, column2 ASC|DESC, ... ;>”
It will return the values selected. To select all columns, you can write an asterisk (*) instead.
The DISTINCT parameter will make any rows that are the same to collapse into one.
The WHERE and ORDER BY statements are optional.
To see more about the WHERE statement, check this part of the documentation .
The ORDER BY will order the columns by the list provided, ASC means ascendant and DESC is descendant. If it’s not specified it will be ASC. If the columns are the same, it will check the next column in the list.
UPDATE
Syntax:” UPDATE table_name SET column1 = value1, column2 = value2, ... <WHERE condition;>”
It will update the columns with the new values provided.
The WHERE statement is optional, if it is not specified, it will update all the rows of the table.
To see more about the WHERE statement, check this part of the documentation .
DELETE
Syntax:” DELETE FROM table_name <WHERE condition>;
It will delete the columns.
The WHERE statement is optional, if it is not specified, it will delete all the rows of the table.
To see more about the WHERE statement, check this part of the documentation .
START TRANSACTION
Syntax: “START TRANSACTION;”
It starts a transaction, any operation performed during the transaction won’t be recorded into the database. Any errors encountered during a transaction will halt the execution of all the queries, including the ones outside the transaction.
END TRANSACTION
Syntax: ”END TRANSACTION:”
It ends a transaction, committing all the changes made during the transaction to the database.
The WHERE statement
Syntax: ”WHERE condition”
It will match the columns that check the conditions. It supports a series of operations:

freemco NES Corelib
This is a reference to the routines available in the freemco NES Corelib, as well as a reference to any tools you may want to use in developing NES games.
Note: This (incomplete) documentation is being phased out in favor of a NaturalDocs-based setup.
Function/Routine Reference
The freemco NES Corelib is split into multiple parts based on the functionality they expose.- Quick Overview (includes
nes.inc
andram.inc
) - PPU (Graphics)
- APU (Sound)
- I/O (Controllers)
- Math
- Utilities
- Mapper-Specific
- Appendix A: Palettes
Tools
When developing NES games, it's useful to have tools around. I mean yeah, you can write an entire NES game with a hex editor if you wanted to, but it's really tedious and requires you to have memorized damn near everything.
Compilers
There are quite a few 6502-targeting compilers out there, but I've only tested and developed this code on ASM6 (and ASM6f).
ASM6
ASM6 is a 6502 compiler and linker by Loopy. The source code is a single C file containing portable code. If you're not afraid of the command line/terminal, ASM6 is available for all platforms. (Though you may need to compile it yourself.)
ASM6f
ASM6f is a fork of ASM6 by freem (hey, that's me!). While it's not required for using the Corelib, its ability to export FCEUX-compatible .nl files may be helpful for debugging.
Graphics
YY-CHR
YY-CHR is a pretty good program for editing the graphics of old video games (assuming the graphics aren't compressed). The .NET version works better in Windows 7, while the original C++ version works better in Windows XP and Wine. The two versions are mostly similar, though the .NET version lacks the Selection tool and the half-tone pattern tools.
Nametables
(todo: tepples' screen tools)NES Screen Tool
Shiru's NES Screen Tool allows you to interactively place tiles, change the palettes and attributes, and also edit the tiles if you need to. Works in Wine, if you're not on Windows. (Unrelated to nametables, it also has a Metasprite builder, which you might find useful.)
Sounds and Music
By no means is this an exhaustive list. This is blatantly missing various MML-based solutions. Do people still use NerdTracker 2?
Famitracker
Famitracker is a very popular NES tracker that supports various sound extensions and has a playback engine available. This engine is good for your games... if all you need to do is play music.
Muse
thefox has made a playback library called MUSE, which is more suited to NES games. Music data is exported from Musetracker (formerly known as "Pornotracker", if you ever see references to that).
Famitone2
Shiru recently released an update to Famitone, an engine capable of handling both sounds and music at the same time.
MetalSlime's Engine
MetalSlime's sound engine is presented as a tutorial in ten parts; the first part is available here. The sound engine I'm working on for the corelib is based off of this tutorial.
GradualGames's Engine
Derek Andrews of Gradual Games has a sound engine supporting four channels of music and two channels of sound effects.
bloopageddon
bloopageddon by ReaperSMS is probably not fit for public consumption yet, based on the todo file. If you are brave enough, you might be able to do something with it.

The Berkeley DB test suite is built if you specify --enable-test as an argument during the UNIX configure process and the Tcl libraries are found on your system. The Berkeley DB test suite needs the Tcl (but not the Tk) library to run. See Building for UNIX platforms for more information.
You can download Tcl from the Scriptics Corporation web site.

3201 William Nicol Drive
Bryanston, Gauteng, South Africa
Abstract:
This session will show you how a better understanding of how the Query Optimizer works can help you to improve the performance of your queries. I will show you some of the top Query Optimizer topics that can give you the most benefit by focusing both on concepts and practical solutions. Several areas of the query processor will be covered, everything from troubleshooting query performance problems and identifying what information the Query Optimizer needs to do a better job to the extreme cases where, because of the its limitations, the Query Optimizer may not give you a good plan and you may need to take a different approach.
Speaker(s): Benjamin Nevarez,
Abstract:
"Data lasts longer than code, treat it right" - In this session we take a look at database design phases, data modelling and some tools to help you along the way.
Speaker(s): Luis de Sousa,
Abstract:
In this session, we will explore the usage and performance of the Microsoft Connector Version 1.1 for Oracle by Attunity. Delegates will leave the session empowered to replace their current SQL Server Integration Packages to use the new connector to dramatically increase data transfer speed between SQL Server and Oracle. The session is a must for BI developers working in heterogeneous environments where Oracle source systems or Data Warehouses and Microsoft BI tools co-exist.
Speaker(s): Phlippie Smit,
Abstract:
(Eng Afrikaans) Within the realm of financial instruments, business structure and rules are highly hierarchical in nature. Investor funds consist of one or many levels of asset ID’s which in turn are comprised of one or more lots. This certainly poses interesting challenges when it comes to creating efficient and effective detailed and summary level queries and reports. This beginners' to intermediate level hands-on presentations is aimed at showing the attendee how we handle recursive scenarios,utilizing several techniques including, recursive T-SQL, code using memory TABLEs (as custom stacks) and CTE's.
Speaker(s): Steve Simon,
Abstract:
As a DBA I always get asked by my DBA peers “How many I/Os, Deadlocks, Scans etc. does your database perform?”. Very valid question but in what context? The starting point of answering the context questions starts with implementing a baseline for your database. In this session I will propose concepts and raise important things to consider when implementing a baseline on a production database.
Speaker(s): Theo Potgieter,
Abstract:
Database performance is a hot topic and there are often questions asked pertaining to the best way to write T-SQL queries. In this presentation, the attendee will NOT be shown the best manner in which to write queries but rather numerous ways of how to write poorly performing queries, with the hope that the attendee will obtain an understanding of what NOT to do. The user will be guided through each query, be shown why it’s not the optimal way of doing things and then shown a well-written query that achieves the same results.
Speaker(s): Gail Shaw,
Abstract:
"Many data are publicly available , including Geographic Information Systems points, and economic metrics. In this session, Mark will show a couple of these sources, and show how to import this geographic and economic information into a SQL database, and display it as a map in SSRS"
Speaker(s): Mark Stacey,
Abstract:
Look at what happens to a transaction in the log file, and take a deep dive into VLF's with a live demo to see how they can affect performance if managed badly.
Speaker(s): Stephan Lawson,
Abstract:
In this session we will explore some practical scripts to help create database documentation. We will be looking at how to make some of those documentation tasks easier, while giving you greater insight into your database(s). Attendees will be able to leave with some additional tools for their toolbox and through the use of these scripts the attendee will be able to perform these tasks faster.
Speaker(s): Jason Brimhall,

used to create UrlRule objects for common cases
Disables monitoring of the URL.
Disables monitoring of the URL.
Call this method before UI-Router has bootstrapped. It will stop UI-Router from performing the initial url sync.
This can be useful to perform some asynchronous initialization before the router starts. Once the initialization is complete, call listen to tell UI-Router to start watching and synchronizing the URL.
// Prevent $urlRouter from automatically intercepting URL changes when it starts;
urlService.deferIntercept();
$http.get('/states.json').then(function(resp) {
resp.data.forEach(state => $stateRegistry.register(state));
urlService.listen();
urlService.sync();
});

$bob = $urlRouter.href(matcher, params);
// $bob == "/about/bob";
The UrlMatcher object which is used as the template of the URL to generate.
An object of parameter values to fill the matcher's required parameters.
Options object. The options are:

- {boolean=false}, If true will generate an absolute url, e.g. "http://www.example.com/fullurl".Returns the fully compiled URL, or null
if params
fail validation against urlMatcher
Starts or stops listening for URL changes
Starts or stops listening for URL changes
Call this sometime after calling deferIntercept to start monitoring the url. This causes UrlRouter to start listening for changes to the URL, if it wasn't already listening.
If called with false
, will stop listening. Call listen() again to start listening
urlService.deferIntercept();
$http.get('/states.json').then(function(resp) {
resp.data.forEach(state => $stateRegistry.register(state));
// Start responding to URL changes
urlService.listen();

Given a URL, check all rules and return the best MatchResult
Given a URL, check all rules and return the best MatchResult
Defines the state, url, or behavior to use when no other rule matches the URL.
Defines the state, url, or behavior to use when no other rule matches the URL.
This rule is matched when no other rule matches. It is generally used to handle unknown URLs (similar to "404" behavior, but on the client side).
handler
a string, it is treated as a url redirectWhen no other url rule matches, redirect to /index
.otherwise('/index');
handler
is an object with a state
property, the state is activated.When no other url rule matches, redirect to home
and provide a dashboard
parameter value.
.otherwise({ state: 'home', params: { dashboard: 'default' } });
handler
is a function, the function receives the current url (UrlParts) and the UIRouter object.
The function can perform actions, and/or return a value.When no other url rule matches, manually trigger a transition to the home
state
.otherwise((matchValue, urlParts, router) => {
router.stateService.go('home');
});
When no other url rule matches, go to home
state
.otherwise((matchValue, urlParts, router) => {
return { state: 'home' };
});

Pushes a new location to the browser history.
Manually adds a URL Rule.
Manually adds a URL Rule.
Usually, a url rule is added using StateDeclaration.url or when. This api can be used directly for more control (to register a BaseUrlRule, for example). Rules can be created using UrlRouter.urlRuleFactory, or create manually as simple objects.
A rule should have a match
function which returns truthy if the rule matched.
It should also have a handler
function which is invoked if the rule is the best match.
a function that deregisters the rule
Gets all registered rules
Gets all registered rules
an array of all the registered rules
Checks the URL for a matching UrlRule
Checks the URL for a matching UrlRule
Checks the current URL for a matching url rule, then invokes that rule's handler. This method is called internally any time the URL has changed.
This effectively activates the state which matches the current URL.
urlService.deferIntercept();
$http.get('/states.json').then(function(resp) {
resp.data.forEach(state => $stateRegistry.register(state));
urlService.listen();
// Find the matching URL and invoke the handler.
urlService.sync();
});

Generated using TypeDoc
Updates URL and responds to URL changes
Deprecation warning:
This class is now considered to be an internal API Use the UrlService instead. For configuring URL rules, use the UrlRulesApi which can be found as UrlService.rules.
This class updates the URL when the state changes. It also responds to changes in the URL.

If first is less than zero, it is considered to refer to before the first element of the list. For non-empty lists, the element indicated by first must exist or first must indicate before the start of the list.
If last is less than first, then any specified elements will be inserted into the list at the point specified by first with no elements being deleted.
The element arguments specify zero or more new arguments to be added to the list in place of those that were deleted. Each element argument will become a separate element of the list. If no element arguments are specified, then the elements between first and last are simply deleted. If list is empty, any element arguments are added to the end of the list.
% lreplace {a b c d e} 1 1 foo a foo c d e
Replacing two elements of a list with three:
% lreplace {a b c d e} 1 2 three more elements a three more elements d e
Deleting the last element from a list in a variable:
% set var {a b c d e} a b c d e % set var [lreplace $var end end] a b c d
A procedure to delete a given element from a list:
proc lremove {listVariable value} { upvar 1 $listVariable var set idx [lsearch -exact $var $value] set var [lreplace $var $idx $idx] }


It is also possible to specify the default sort order for a page. In the example below data are sorted by the Continent column in ascending order, then by the Population column in descending order.
Note that removing all columns from the sort order will restore the default ordering.

Choosing Signature
The last step to set up your signature is to select in the Mail.app preferences. To do so simply open the preferences and choose the signatures section. (As seen in Figure 1.1)
1. Drag the new signature from the All Signatures area to your account
2. Click on your account in the left hand pane and then
3. Click on the new signature and
4. Choose Signature - choose your new signature.
5. Close the window
The next couple steps aren't needed but will remove the ?s from showing up when you are writing your message - the signature does send correctly but doesn't appear correctly in your message window at first.
6. Create and send a new email to yourself using the new signature in order to see if it works.
7. Check your email again and view your new signature - the ?s will disappear when writing an email now.


In this scenario, you can pick any of the tile templates and insert your own text and images to see what they look like.
Ensure that the tile size matches the template size you are using.
Select a template, fill in text and images, and configure branding
Template preview:
Images
Images can use
http:// - web images
appx:/// - images in the .appx package
ms-appdata:///local/ - images saved in the app's local storage
For more information, see the Image Protocols scenario.
You can also copy your own images to this app's local storage to test them in a notification.
You can use the following local files:
ms-appx:///images/graySquare150x150.png
ms-appx:///images/redWide310x150.png
ms-appx:///images/blueWide310x150.png
ms-appx:///images/purpleSquare310x310.png

Branding
Applications can choose to use different branding for each notification, which impacts
the layout of the template. If a logo or name is shown on the tile, some text fields
will not display in certain templates. For example, if you send a notification with
TileWide310x150Text06 with a logo, text fields 9 and 10 are clipped.
Some templates do not allow for the branding to be set to the name. If the branding is
set to the name, these templates will just fallback to showing a logo.
Logo - specified in the manifest (default if branding is omitted)
Name - specified in the manifest
None - doesn't show logo or name

BitShares Core
BitShares Core is the BitShares blockchain implementation and command-line interface. The web wallet is BitShares UI.
Visit BitShares.org to learn about BitShares and join the community at BitSharesTalk.org.
NOTE: The official BitShares git repository location, default branch, and submodule remotes were recently changed. Existing repositories can be updated with the following steps:
git remote set-url origin https://github.com/bitshares/bitshares-core.git
git checkout master
git remote set-head origin --auto
git pull
git submodule sync --recursive
git submodule update --init --recursive
Getting Started
Build instructions and additional documentation are available in the wiki.
We recommend building on Ubuntu 16.04 LTS, and the build dependencies may be installed with:
sudo apt-get update
sudo apt-get install autoconf cmake git libboost-all-dev libssl-dev g++ libcurl4-openssl-dev
To build after all dependencies are installed:
git clone https://github.com/bitshares/bitshares-core.git
cd bitshares-core
git checkout <LATEST_RELEASE_TAG>
git submodule update --init --recursive
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .
make
NOTE: BitShares requires an OpenSSL version in the 1.0.x series. OpenSSL 1.1.0 and newer are NOT supported. If your system OpenSSL version is newer, then you will need to manually provide an older version of OpenSSL and specify it to CMake using -DOPENSSL_INCLUDE_DIR
, -DOPENSSL_SSL_LIBRARY
, and -DOPENSSL_CRYPTO_LIBRARY
.
NOTE: BitShares requires a Boost version in the range [1.57, 1.63]. Versions earlier than
1.57 or newer than 1.63 are NOT supported. If your system Boost version is newer, then you will need to manually build
an older version of Boost and specify it to CMake using DBOOST_ROOT
.
After building, the witness node can be launched with:
./programs/witness_node/witness_node
The node will automatically create a data directory including a config file. It may take several hours to fully synchronize
the blockchain. After syncing, you can exit the node using Ctrl+C and setup the command-line wallet by editing
witness_node_data_dir/config.ini
as follows:
rpc-endpoint = <IP_ADDRESS>:8090
NOTE: By default the witness node will start in reduced memory ram mode by using some of the commands detailed in Memory reduction for nodes.
In order to run a full node with all the account history you need to remove partial-operations
and max-ops-per-account
from your config file. Please note that currently(2017-12-23) a full node need 54GB of RAM to operate and required memory is growing fast.
After starting the witness node again, in a separate terminal you can run:
./programs/cli_wallet/cli_wallet
Set your inital password:
>>> set_password <PASSWORD>
>>> unlock <PASSWORD>
To import your initial balance:
>>> import_balance <ACCOUNT NAME> [<WIF_KEY>] true
If you send private keys over this connection, rpc-endpoint
should be bound to localhost for security.
Use help
to see all available wallet commands. Source definition and listing of all commands is available
here.
Support
Technical support is available in the BitSharesTalk technical support subforum.
BitShares Core bugs can be reported directly to the issue tracker.
BitShares UI bugs should be reported to the UI issue tracker
Using the API
We provide several different API's. Each API has its own ID.
When running witness_node
, initially two API's are available:
API 0 provides read-only access to the database, while API 1 is
used to login and gain access to additional, restricted API's.
Here is an example using wscat
package from npm
for websockets:
$ npm install -g wscat
$ wscat -c ws://<IP_ADDRESS>:8090
> {"id":1, "method":"call", "params":[0,"get_accounts",[["1.2.0"]]]}
< {"id":1,"result":[{"id":"1.2.0","annotations":[],"membership_expiration_date":"1969-12-31T23:59:59","registrar":"1.2.0","referrer":"1.2.0","lifetime_referrer":"1.2.0","network_fee_percentage":2000,"lifetime_referrer_fee_percentage":8000,"referrer_rewards_percentage":0,"name":"committee-account","owner":{"weight_threshold":1,"account_auths":[],"key_auths":[],"address_auths":[]},"active":{"weight_threshold":6,"account_auths":[["1.2.5",1],["1.2.6",1],["1.2.7",1],["1.2.8",1],["1.2.9",1],["1.2.10",1],["1.2.11",1],["1.2.12",1],["1.2.13",1],["1.2.14",1]],"key_auths":[],"address_auths":[]},"options":{"memo_key":"GPH1111111111111111111111111111111114T1Anm","voting_account":"1.2.0","num_witness":0,"num_committee":0,"votes":[],"extensions":[]},"statistics":"2.7.0","whitelisting_accounts":[],"blacklisting_accounts":[]}]}
We can do the same thing using an HTTP client such as curl
for API's which do not require login or other session state:
$ curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0, "get_accounts", [["1.2.0"]]], "id": 1}' http://<IP_ADDRESS>:8090/rpc

API 0 is accessible using regular JSON-RPC:
$ curl --data '{"jsonrpc": "2.0", "method": "get_accounts", "params": [["1.2.0"]], "id": 1}' http://<IP_ADDRESS>:8090/rpc
Accessing restricted API's
You can restrict API's to particular users by specifying an api-access
file in config.ini
or by using the --api-access /full/path/to/api-access.json
startup node command. Here is an example api-access
file which allows
user bytemaster
with password supersecret
to access four different API's, while allowing any other user to access the three public API's
necessary to use the wallet:
{
"permission_map" :
[
[
"bytemaster",
{
"password_hash_b64" : "9e9GF7ooXVb9k4BoSfNIPTelXeGOZ5DrgOYMj94elaY=",
"password_salt_b64" : "INDdM6iCi/8=",
"allowed_apis" : ["database_api", "network_broadcast_api", "history_api", "network_node_api"]
}
],
[
"*",
{
"password_hash_b64" : "*",
"password_salt_b64" : "*",
"allowed_apis" : ["database_api", "network_broadcast_api", "history_api"]
}
]
]
}
Passwords are stored in base64
as salted sha256
hashes. A simple Python script, saltpass.py
is avaliable to obtain hash and salt values from a password.
A single asterisk "*"
may be specified as username or password hash to accept any value.
With the above configuration, here is an example of how to call add_node
from the network_node
API:
{"id":1, "method":"call", "params":[1,"login",["bytemaster", "supersecret"]]}
{"id":2, "method":"call", "params":[1,"network_node",[]]}
{"id":3, "method":"call", "params":[2,"add_node",["<IP_ADDRESS>:9090"]]}
Note, the call to network_node
is necessary to obtain the correct API identifier for the network API. It is not guaranteed that the network API identifier will always be 2
.
Since the network_node
API requires login, it is only accessible over the websocket RPC. Our doxygen
documentation contains the most up-to-date information
about API's for the witness node and the
wallet.
If you want information which is not available from an API, it might be available
from the database;
it is fairly simple to write API methods to expose database methods.
FAQ
-
Is there a way to generate help with parameter names and method descriptions?
Yes. Documentation of the code base, including APIs, can be generated using Doxygen. Simply run
doxygen
in this directory.If both Doxygen and perl are available in your build environment, the CLI wallet's
help
andgethelp
commands will display help generated from the doxygen documentation.If your CLI wallet's
help
command displays descriptions without parameter names likesigned_transaction transfer(string, string, string, string, string, bool)
it means CMake was unable to find Doxygen or perl during configuration. If found, the output should look like this:signed_transaction transfer(string from, string to, string amount, string asset_symbol, string memo, bool broadcast)
-
Is there a way to allow external program to drive
cli_wallet
via websocket, JSONRPC, or HTTP?Yes. External programs may connect to the CLI wallet and make its calls over a websockets API. To do this, run the wallet in server mode, i.e.
cli_wallet -s "<IP_ADDRESS>:9999"
and then have the external program connect to it over the specified port (in this example, port 9999). -
Is there a way to access methods which require login over HTTP?
No. Login is inherently a stateful process (logging in changes what the server will do for certain requests, that's kind of the point of having it). If you need to track state across HTTP RPC calls, you must maintain a session across multiple connections. This is a famous source of security vulnerabilities for HTTP applications. Additionally, HTTP is not really designed for "server push" notifications, and we would have to figure out a way to queue notifications for a polling client.
Websockets solves all these problems. If you need to access Graphene's stateful methods, you need to use Websockets.
-
What is the meaning of
a.b.c
numbers?The first number specifies the space. Space 1 is for protocol objects, 2 is for implementation objects. Protocol space objects can appear on the wire, for example in the binary form of transactions. Implementation space objects cannot appear on the wire and solely exist for implementation purposes, such as optimization or internal bookkeeping.
The second number specifies the type. The type of the object determines what fields it has. For a complete list of type ID's, see
enum object_type
andenum impl_object_type
in types.hpp.The third number specifies the instance. The instance of the object is different for each individual object.
-
The answer to the previous question was really confusing. Can you make it clearer?
All account ID's are of the form
1.2.x
. If you were the 9735th account to be registered, your account's ID will be1.2.9735
. Account0
is special (it's the "committee account," which is controlled by the committee members and has a few abilities and restrictions other accounts do not).All asset ID's are of the form
1.3.x
. If you were the 29th asset to be registered, your asset's ID will be1.3.29
. Asset0
is special (it's BTS, which is considered the "core asset").The first and second number together identify the kind of thing you're talking about (
1.2
for accounts,1.3
for assets). The third number identifies the particular thing. -
How do I get the
network_add_nodes
command to work? Why is it so complicated?You need to follow the instructions in the "Accessing restricted API's" section to allow a username/password access to the
network_node
API. Then you need to pass the username/password to thecli_wallet
on the command line or in a config file.It's set up this way so that the default configuration is secure even if the RPC port is publicly accessible. It's fine if your
witness_node
allows the general public to query the database or broadcast transactions (in fact, this is how the hosted web UI works). It's less fine if yourwitness_node
allows the general public to control which p2p nodes it's connecting to. Therefore the API to add p2p connections needs to be set up with proper access controls.

portBASE_TYPE xTaskCreateRestricted( xTaskParameters *pxTaskDefinition, xTaskHandle *pxCreatedTask );
xTaskCreateRestricted() should only be used in systems that include an MPU implementation.
Create a new task and add it to the list of tasks that are ready to run. The function parameters define the memory regions and associated access permissions allocated to the task.
| pxTaskDefinition | Pointer to a structure that contains a member for each of the normal xTaskCreate() parameters (see the xTaskCreate() API documentation) plus an optional stack buffer and the memory region definitions. |
| pxCreatedTask | Used to pass back a handle by which the created task can be referenced. |
Example usage:
// Create an xTaskParameters structure that defines the task to be created. static const xTaskParameters xCheckTaskParameters = { vATask, // pvTaskCode - the function that implements the task. "ATask", // pcName - just a text name for the task to assist debugging. 100, // usStackDepth - the stack size DEFINED IN WORDS. NULL, // pvParameters - passed into the task function as the function parameters. ( 1UL | portPRIVILEGE_BIT ),// uxPriority - task priority, set the portPRIVILEGE_BIT if the task should run in a privileged state. cStackBuffer,// puxStackBuffer - the buffer to be used as the task stack.
// xRegions - Allocate up to three separate memory regions for access by // the task, with appropriate access permissions. Different processors have // different memory alignment requirements - refer to the FreeRTOS documentation // for full information. { // Base address Length Parameters { cReadWriteArray, 32, portMPU_REGION_READ_WRITE }, { cReadOnlyArray, 32, portMPU_REGION_READ_ONLY }, { cPrivilegedOnlyAccessArray, 128, portMPU_REGION_PRIVILEGED_READ_WRITE } } };
int main( void ) { xTaskHandle xHandle;// Create a task from the const structure defined above. The task handle // is requested (the second parameter is not NULL) but in this case just for // demonstration purposes as its not actually used. xTaskCreateRestricted( &xRegTest1Parameters, &xHandle ); // Start the scheduler. vTaskStartScheduler(); // Will only get here if there was insufficient memory to create the idle // task. for( ;; );}
h
void vTaskAllocateMPURegions( xTaskHandle xTask, const xMemoryRegion * const pxRegions );
Memory regions are assigned to a restricted task when the task is created by a call to xTaskCreateRestricted(). These regions can be redefined using vTaskAllocateMPURegions().
| xTask | The handle of the task being updated. |
| xRegions | A pointer to an xMemoryRegion structure that contains the new memory region definitions. |
Example usage:
// Define an array of xMemoryRegion structures that configures an MPU region // allowing read/write access for 1024 bytes starting at the beginning of the // ucOneKByte array. The other two of the maximum 3 definable regions are // unused so set to zero. static const xMemoryRegion xAltRegions[ portNUM_CONFIGURABLE_REGIONS ] = { // Base address Length Parameters { ucOneKByte, 1024, portMPU_REGION_READ_WRITE }, { 0, 0, 0 }, { 0, 0, 0 } };
void vATask( void *pvParameters ) { // This task was created such that it has access to certain regions of // memory as defined by the MPU configuration. At some point it is // desired that these MPU regions are replaced with that defined in the // xAltRegions const struct above. Use a call to vTaskAllocateMPURegions() // for this purpose. NULL is used as the task handle to indicate that this // function should modify the MPU regions of the calling task. vTaskAllocateMPURegions( NULL, xAltRegions );
// Now the task can continue its function, but from this point on can only // access its stack and the ucOneKByte array (unless any other statically // defined or shared regions have been declared elsewhere). }
