Affirmation: Combating Stereotype Threat
This is an exercise in affirmation. Let's see where it goes.
I really value mentoring other people. This is something I have been doing for a while, and have had the opportunity to expand upon in my current profession.
Why do I enjoy mentoring? I guess it makes me feel like I am doing something that actually matters. Also there is something about being able to give advice to someone that validates me as a person. If I know what I know, and have experienced what I have experienced, but do not share that with anyone, what good is it?
The last time someone asked me for advice, it was actually a married couple who are about to have a child. They wanted advice on coming to an agreement on how to order their priorities over the next several months. One spouse wants to do one thing, the other spouse wants to do something else. This is something I have experienced personally, and thus was able to guide this couple, without giving them an "answer", since they have to come up with an agreement that works best for them.
When I think about this interaction, it connects with some values I hold strongly: close relationships, meaningful work, wisdom, commitment, growth. Hey, maybe this is why I like doing this!
Ok the affirmation exercise is done. How do I feel? Pretty good! This type of exercise would definitely help if I experience stereotype threat. We all live by the words that have been spoken to us and by us. When our minds start to turn inward against themselves (whether because of what someone else said to us, or what we are saying to ourselves), we need to be able to pull ourselves out of that abyss. Positive words are the only way to do this. We need words of encouragement to balance our negative thinking.
The real question is, why do we tend toward negative thinking at all? Are we tearing other people down to make ourselves feel better? Are we tearing ourselves down to protect ourselves from something we fear even more? If we can control our words, both spoken and our internal monologues, we can control any part of our lives. But can anyone do that 100%?

| PostgreSQL 9.0.10 Documentation | ||||
|---|---|---|---|---|
| Prev | Up | Chapter 40. PL/Tcl - Tcl Procedural Language | Next |
Trigger procedures can be written in PL/Tcl. PostgreSQL requires that a procedure that is to be called as a trigger must be declared as a function with no arguments and a return type of trigger.
The information from the trigger manager is passed to the procedure body in the following variables:
The name of the trigger from the CREATE TRIGGER statement.
The object ID of the table that caused the trigger procedure to be invoked.
The name of the table that caused the trigger procedure to be invoked.
The schema of the table that caused the trigger procedure to be invoked.
A Tcl list of the table column names, prefixed with an empty list
element. So looking up a column name in the list with Tcl's
lsearch
command returns the element's number starting
with 1 for the first column, the same way the columns are customarily
numbered in PostgreSQL. (Empty list
elements also appear in the positions of columns that have been
dropped, so that the attribute numbering is correct for columns
to their right.)
The string BEFORE or AFTER depending on the type of trigger event.
The string ROW or STATEMENT depending on the type of trigger event.
The string INSERT, UPDATE, DELETE, or TRUNCATE depending on the type of trigger event.
An associative array containing the values of the new table row for INSERT or UPDATE actions, or empty for DELETE. The array is indexed by column name. Columns that are null will not appear in the array. This is not set for statement-level triggers.
An associative array containing the values of the old table row for UPDATE or DELETE actions, or empty for INSERT. The array is indexed by column name. Columns that are null will not appear in the array. This is not set for statement-level triggers.
A Tcl list of the arguments to the procedure as given in the CREATE TRIGGER statement. These arguments are also accessible as $1 ... $n in the procedure body.
The return value from a trigger procedure can be one of the strings OK or SKIP, or a list as returned by the array get Tcl command. If the return value is OK, the operation (INSERT/UPDATE/DELETE) that fired the trigger will proceed normally. SKIP tells the trigger manager to silently suppress the operation for this row. If a list is returned, it tells PL/Tcl to return a modified row to the trigger manager that will be inserted instead of the one given in $NEW. (This works for INSERT and UPDATE only.) Needless to say that all this is only meaningful when the trigger is BEFORE and FOR EACH ROW; otherwise the return value is ignored.
Here's a little example trigger procedure that forces an integer value in a table to keep track of the number of updates that are performed on the row. For new rows inserted, the value is initialized to 0 and then incremented on every update operation.
CREATE FUNCTION trigfunc_modcount() RETURNS trigger AS $$ switch $TG_op { INSERT { set NEW($1) 0 } UPDATE { set NEW($1) $OLD($1) incr NEW($1) } default { return OK } } return [array get NEW] $$ LANGUAGE pltcl; CREATE TABLE mytab (num integer, description text, modcnt integer); CREATE TRIGGER trig_mytab_modcount BEFORE INSERT OR UPDATE ON mytab FOR EACH ROW EXECUTE PROCEDURE trigfunc_modcount('modcnt');
Notice that the trigger procedure itself does not know the column name; that's supplied from the trigger arguments. This lets the trigger procedure be reused with different tables.

which offer native mixing (i.e. Linux ALSA with hardware mixing,
Solaris Mixer enabled, Windows DirectSound).
- The new real-time Sequencer works with all MIDI devices and
allows unlimited Transmitters (RFE 4773012).
- The
sound.properties
configuration file allows
choice of default devices (RFE 4776511). For details, see
MidiSystem
and AudioSystem
for
details.
- MidiDevices can query connected Receivers and Transmitters (RFE
4931387, methods MidiDevice.getReceiver and
MidiDevice.getTransmitter).
AudioFormat
, AudioFileFormat
, and
MidiFileFormat
now have properties that allow further
description and qualification of the format (RFEs 4925767 and
4666845).
- A set of ease-of-use methods allow easier retrieval of lines
from AudioSystem (RFE 4896221).
- The Sequencer interface is extended with loop methods, for
seamless looping of specific portions of a MIDI sequence (RFE
4204105).
- Java Sound no longer prevents the VM from exiting (bug
4735740).


[gecode-users] How to set an arbitrary RandomGenerator for randomized branching?!?
Christian Schulte

Even that is not enough! It also needs to work with recomputation, that's
why each branching actually needs to store the entire state of a random
number generator.

A problem with your approach is that a global random number generator
doesn't work in a multi-threaded setting (you don't want to lock
access to it, I think). One would at least have to have it per thread.

Jason Manford on bringing award-winning musical comedy Curtains to Belfast
Comedian Jason Manford is starring in a brand-new production of the Tony Award-winning musical Curtains this week at Grand Opera House, Belfast. We caught up with Jason to quiz him about the show
CAN you tell us a little about Curtains?
The show was a huge success on Broadway so it's really exciting to be bringing this new production to Belfast. It's a comedy musical 'whodunit?' and I play a detective, Frank Cioffi, who is obsessed with musicals.
When a murder happens in a theatre, he, along with the audience, turns up to discover who the killer is. It's written by Kander and Ebb who wrote Chicago and Cabaret, so the music is great and it's a hilarious script.
Did you know the show before coming on board?
I didn't know much, but as soon as I would mention it to friends in theatre they would say, "That's one of my favourite shows". It's a popular musical within the theatre community and I'm excited that we can share this love to cities all over the UK.
What appealed to you about taking on the role?
What I love about Frank is that he's such a sweet guy, even considering he's there to solve a murder. He loves theatre but hasn't had the chance to be on stage, and that's not dissimilar from how I started.
I came from a different world, coming from stand-up comedy and television,and was surrounded by these hugely talented actors and performers, so I can relate to that a bit. There's something in him that is just fun to play with as an actor.
How did you prepare for the role?
The first thing I had to do was adapt to the Boston accent. I've done New York a couple of times as I was Leo Bloom in The Producers and Nathan Detroit in Guys and Dolls so I know my way around a New York accent.
However, a Boston accent was a new challenge. We got to work with an accent coach, and I watched lots of videos and films set in Boston to get an ear for it. We've also got a few dance numbers, so I hit the gym to prepare for that.
Do you prefer performing in theatre to stand up comedy?
I just find that there are times when stand-up is number one, and there are times when it's theatre. With stand-up I'm starting with a blank page – I sit down and think about what I want to tell stories and jokes about, whereas with musicals somebody else is setting the parameters that I then get to explore and play in.
There's something quite exciting about that – someone saying here are the rules, a script, story, songs, and then you've got to use what you've got to collaborate with them, with what pre-exists. It's actually a really good discipline, and I've been able to use some of the skills I've learned in theatre and translate them to how I perform stand-up comedy.
What was your very first experience of musical theatre?
I remember being about nine or 10 at school, and I don't know how they got away with it, but they took us to see Sweeney Todd. It was quite an experience, and I remember thinking it was just brilliant. I was in every musical I could be at high school, whether it was my year group or not I would badger the teacher until they let me be a part of it somehow.
Then, when I got to university they didn't have a drama society, so I actually set one up at Salford University called Almost Famous. That's still going now and I get invited to stuff by them all the time which is really nice. I actually also wrote a couple of musicals myself when I was at uni.
Do you have a role you'd love to play?
Yeah, I'd like to play Jean Valjean in Les Misérables at some point. That feels like the ultimate aim.
Have you ever been given a piece of advice or some words of wisdom that have stuck with you?
I've had quite a bit actually over the years. I remember Peter Kay telling me when I first started stand-up that the rest of the country is working a 40-hour week at least, so just because you work in show business why should you be any different?
As a comic, if you wanted to, you could probably get away with working for 20 minutes a night, four nights a week – but he was a real inspiration to get me to say 'OK, what am I doing with the rest of my time?' He made me write a lot more and do a lot more.
I also remember doing Sweeney Todd and feeling really nervous around these incredible singers, dancers and actors. I said to Michael Ball that I feel like I'm winging it, that I'm on that TV show Faking It, and he said to me "darling, we're all on Faking It", which I thought was good advice as it reassured me we are all sort of winging it, to a point!
My dad always used to say to me "Your horizon should become your middle distance" so that you aim for things and, when you get there, you head on to the next thing. That's a great piece of advice.
Finally, what can audiences expect when they come and see Curtains?
They can expect great music from the team behind Cabaret and Chicago, a wonderful and talented cast, hilarious comedy, and you'll be questioning right the way through to the end – whodunit?!
:: Curtains is on now at Grand Opera House, Belfast, until Saturday November 23. See Goh.co.uk for showtimes and tickets


_Anna_and_the_King_ (PG-13) *** (out of ****)
Fox chose an ideal year to produce and release Andy Tennant's lavish non-musical treatment of the oft-told true story of the meeting of minds between King Mongkut (Chow Yun-Fat) and English schoolteacher Anna Leonowens (Jodie Foster) in 1862 Siam. After all, it can only look good compared to this year's other screen version of the tale, Warner Bros.' woefully misguided animated adaptation of Rodgers and Hammerstein's venerable musical _The_King_and_I_. That fact aside, however, _Anna_, while taking the occasional dramatic misstep, is a pretty solid drama on its own terms, boasting beautiful pageantry, smart political intrigue, and a convincing rapport between leads.
While they are a unit for most of the film, taken individually, Foster and Chow have differing degrees of success. Foster is good, but her performance is a big step down from her Oscar-caliber work of recent years (last in 1997's _Contact_), hampered by an accent that is only sporadically convincing. Chow, on the other hand, is terrific. Although he made a name for himself in Hong Kong as an action star, the King is the first American role where he really shows the key to his appeal--it's not necessarily the gun(s) in his hand(s), but his suave charm and charisma. He's also a solid dramatic actor; not for nothing do his legendary collaborations with John Woo have such a potent emotional impact. Anna may get top billing in this retelling, but it's the king who commands the show.

Nirvana was an American rock band that was formed by singer and guitarist Kurt Cobain and bassist Krist Novoselic in Aberdeen, Washington, in 1987. Nirvana went through a succession of drummers, the longest-lasting being Dave Grohl, who joined the band in 1990. Despite releasing only three full-length studio albums in their seven-year career, Nirvana has come to be regarded as one of the most influential and important rock bands of the modern era.
In the late 1980s, Nirvana established itself as part of the Seattle grunge scene, releasing its first album Bleach for the independent record label Sub Pop in 1989. The band eventually came to develop a sound that relied on dynamic contrasts, often between quiet verses and loud, heavy choruses. After signing to major label DGC Records, Nirvana found unexpected success with "Smells Like Teen Spirit", the first single from the band's second album Nevermind (1991).
Nirvana's sudden success widely popularized alternative rock as a whole, and the band's frontman Cobain found himself referred to in the media as the "spokesman of a generation", with Nirvana being considered the "flagship band" of Generation X.[1] In response, Nirvana's third studio album, In Utero (1993), featured an abrasive, less-mainstream sound and challenged the group's audience. The album did not match the sales figures of Nevermind, but was still a commercial success and critically acclaimed.
Nirvana's brief run ended following the death of Kurt Cobain in 1994, but various posthumous releases have been issued since, overseen by Novoselic, Grohl, and Cobain's widow Courtney Love. Since its debut, the band has sold over 25 million records in the United States alone, and over 75 million records worldwide, making them one of the best-selling bands of all time.[2][3] Nirvana was inducted into the Rock and Roll Hall of Fame in 2014, in its first year of eligibility.

Using WQL almost any hardware or operating system event can be set as and event trigger. I highly recommend that you take some time to review the Win32 Provider Classes to get an understanding of the scope of these events. As always, the best way to learn is to try to formulate some queries on your local host. In powershell the Get-WmiObject cmdlet can be used, in conjunction with the provided link, to get instances of WMI classes.
# Cursory information can be retrieved by only specifying the class name.
PS C:\Windows\system32> Get-WmiObject -class Win32_CDROMDrive
# Using the ConfigManagerErrorCode property we can check if the drive is functioning normally.
PS C:\Windows\system32> Get-WmiObject -query "select ConfigManagerErrorCode from Win32_CDROMDrive"
# Using the Capabilities property we can check capabilities of the device.
PS C:\Windows\system32> Get-WmiObject -query "select Capabilities from Win32_CDROMDrive"
# Using the MediaLoaded property we can check if the drive currently has a CD-Rom.
PS C:\Windows\system32> Get-WmiObject -query "select MediaLoaded from Win32_CDROMDrive"
As an example could create a WQL event trigger which would wait for a CD-Rom to be inserted into a drive on the system. When the WQL query determins a CD-Rom drive has been inserted it will then trigger an action. The sample WQL query can been seen below.
# Notice that we are checking for an instance modification where the value for "MediaLoaded" changes from
"False" to "True".
Query = "SELECT * FROM __InstanceModificationEvent Within 5"
"Where TargetInstance Isa \"Win32_CDROMDrive\" "
"And Targetinstance.MediaLoaded = \"True\" ";

It is often required that, a user register's or sign up to login to a particular website or application. It is a tedious job to fill those long forms with user basic details. To avoid filling long forms, Cuppa Angular 2 OAuth provides a module to login using social OAuth services like google OAtuh, Facebook OAuth and LinkedIn OAuth. Using this your application will be able to recieve basic details of the user from social networking sites and you can store in your application environment.
To get started using the Cuppa OAuth Social Login, the following pre requisites needs to be met with. 1) Knowledge of Angular 2 and latest Angular 2 version. Refer Setup AngularJS 2) Knowledge of NodeJS and latest version installed in your environment. Refer Setup NodeJS 3) Installed MongoDB and knowledge of setting up. Refer Setup MongoDB 4) Set up Angular Client, App Server(your node server), Mongo DB.
Follow the steps to install the Cuppa OAuthcode in your environment. 1) Clone https://github.com/CuppaLabs/angular2-social-login.git repository from github. 2) $ npm install - To install all the dependencies 3) $ npm run auth-server - To start the server (Run only when the entire application is setup).
To configure angular, the urls need to be changed to your environment url endpoints. 1) Go to src/app/auth.service.ts 2) Replace the baseURL with your endpoint(http://localhost:500, to run locally), as shown in the below snippet 3) Create your social app with Google/Facebook/LinkedIn and get you client ID 4) Replace the Client ID in the authConfig Object as shown below in the snippet.(blurred area) 4) redirectURI - the redirect url configured in the social networking app which redirects to your page on that URL, on successful login 5) authEndpoint - Your application server endpoint where it hits for authentication.
To configure Node Server, follow the below steps 1) Go to /auth-config.js 2) Create your social app with Google/Facebook/LinkedIn and get the client secret. 3) Replace the client secret with your app's client secret as show in the below snippet. (Blurred my credentials). Place your credentials there.
To configure Node Server with mongo DB details, follow the below steps 1) Install Mongo DB locally and start or deploy on any cloud platform 2) Go to /auth-config.js 3) Replace the username, password, mongo url and DB name. Form the url as follows and replcae as shown in the below snippet.
Ahh !!! Now you are ready to make your app up and running. 1) Start MongoDB Server 2) $ npm run build 3) $ npm run auth-server 4) Visit http://localhost:5000 to access your app running in your local. This should be the baseURL you configured in the angular configuration section. Deploy to your application server or any cloud platform.
1) Visit Google API Console 2) Go to "Credentials" tab. 3) Select "OAuth Client ID"" from "Create credentials"" tab. 4) Select "web application"" option. 5) Provide your application name, URL of your app origin and redirect URL and Click Create. 6) On creating successfully, you will see the following screen with client ID and client secret.
1) Visit Facebook Apps 2) Click "Add a New App" button.Fill the details and click "Create ID" 3) Select "Facebook Login" from product list and click "Get Started" 4) Provide redirect URL. 6) On creating successfully, you will see the following screen with client ID and client secret.

By bmerry TopCoder Member Introduction Most of the optimizations that go into TopCoder contests are high-level; that is, they affect the algorithm rather than the implementation. However, one of the most useful and effective low-level optimizations is bit manipulation, or using the bits of an integer to represent a set. Not only does it produce an order-of-magnitude improvement in both speed and size, it can often simplify code at the same time. I'll start by briefly recapping the basics, before going on to cover more advanced techniques. The basics At the heart of bit manipulation are the bit-wise operators & (and), | (or), ~ (not) and ^ (xor). The first three you should already be familiar with in their boolean forms (&&, || and !). As a reminder, here are the truth tables:
The bit-wise versions of the operations are the same, except that instead of interpreting their arguments as true or false, they operate on each bit of the arguments. Thus, if A is 1010 and B is 1100, then
In general, we will use an integer to represent a set on a domain of up to 32 values (or 64, using a 64-bit integer), with a 1 bit representing a member that is present and a 0 bit one that is absent. Then the following operations are quite straightforward, where ALL_BITS is a number with 1's for all bits corresponding to the elements of the domain:
In this section I'll consider the problems of finding the highest and lowest 1 bit in a number. These are basic operations for splitting a set into its elements. Finding the lowest set bit turns out to be surprisingly easy, with the right combination of bitwise and arithmetic operators. Suppose we wish to find the lowest set bit of x (which is known to be non-zero). If we subtract 1 from x then this bit is cleared, but all the other one bits in x remain set. Thus, x & ~(x - 1) consists of only the lowest set bit of x. However, this only tells us the bit value, not the index of the bit. If we want the index of the highest or lowest bit, the obvious approach is simply to loop through the bits (upwards or downwards) until we find one that is set. At first glance this sounds slow, since it does not take advantage of the bit-packing at all. However, if all 2N subsets of the N-element domain are equally likely, then the loop will take only two iterations on average, and this is actually the fastest method. The 386 introduced CPU instructions for bit scanning: BSF (bit scan forward) and BSR (bit scan reverse). GCC exposes these instructions through the built-in functions __builtin_ctz (count trailing zeros) and __builtin_clz (count leading zeros). These are the most convenient way to find bit indices for C++ programmers in TopCoder. Be warned though: the return value is undefined for an argument of zero. Finally, there is a portable method that performs well in cases where the looping solution would require many iterations. Use each byte of the 4- or 8-byte integer to index a precomputed 256-entry table that stores the index of the highest (lowest) set bit in that byte. The highest (lowest) bit of the integer is then the maximum (minimum) of the table entries. This method is only mentioned for completeness, and the performance gain is unlikely to justify its use in a TopCoder match. Counting out the bits One can easily check if a number is a power of 2: clear the lowest 1 bit (see above) and check if the result is 0. However, sometimes it is necessary to know how many bits are set, and this is more difficult. GCC has a function called __builtin_popcount which does precisely this. However, unlike __builtin_ctz, it does not translate into a hardware instruction (at least on x86). Instead, it uses a table-based method similar to the one described above for bit searches. It is nevertheless quite efficient and also extremely convenient. Users of other languages do not have this option (although they could re-implement it). If a number is expected to have very few 1 bits, an alternative is to repeatedly extract the lowest 1 bit and clear it. All the subsets A big advantage of bit manipulation is that it is trivial to iterate over all the subsets of an N-element set: every N-bit value represents some subset. Even better, if A is a subset of B then the number representing A is less than that representing B, which is convenient for some dynamic programming solutions. It is also possible to iterate over all the subsets of a particular subset (represented by a bit pattern), provided that you don't mind visiting them in reverse order (if this is problematic, put them in a list as they're generated, then walk the list backwards). The trick is similar to that for finding the lowest bit in a number. If we subtract 1 from a subset, then the lowest set element is cleared, and every lower element is set. However, we only want to set those lower elements that are in the superset. So the iteration step is just i = (i - 1) & superset. Even a bit wrong scores zero There are a few mistakes that are very easy to make when performing bit manipulations. Watch out for them in your code.
There are a few other tricks that can be done with bit manipulation. They're good for amazing your friends, but generally not worth the effect to use in practice.
Sample problems TCCC 2006, Round 1B Medium For each city, keep a bit-set of the neighbouring cities. Once the part-building factories have been chosen (recursively), ANDing together these bit-sets will give a bit-set which describes the possible locations of the part-assembly factories. If this bit-set has k bits, then there are kCm ways to allocate the part-assembly factories. TCO 2006, Round 1 Easy The small number of nodes strongly suggests that this is done by considering all possible subsets. For every possible subset we consider two possibilities: either the smallest-numbered node does not communicate at all, in which case we refer back to the subset that excludes it, or it communicates with some node, in which case we refer back to the subset that excludes both of these nodes. The resulting code is extremely short: static int dp[1 << 18]; int SeparateConnections::howMany(vector <string> mat) { int N = mat.size(); int N2 = 1 << N; dp[0] = 0; for (int i = 1; i < N2; i++) { int bot = i & ~(i - 1); int use = __builtin_ctz(bot); dp[i] = dp[i ^ bot]; for (int j = use + 1; j < N; j++) if ((i & (1 << j)) && mat[use][j] == 'Y') dp[i] = max(dp[i], dp[i ^ bot ^ (1 << j)] + 2); } return dp[N2 - 1]; }SRM 308, Division 1 Medium The board contains 36 squares and the draughts are indistinguishable, so the possible positions can be encoded into 64-bit integers. The first step is to enumerate all the legal moves. Any legal move can be encoded using three bit-fields: a before state, an after state and a mask, which defines which parts of the before state are significant. The move can be made from the current state if (current & mask) == before; if it is made, the new state is (current & ~mask) | after. SRM 320, Division 1 Hard The constraints tell us that there are at most 8 columns (if there are more, we can swap rows and columns), so it is feasible to consider every possible way to lay out a row. Once we have this information, we can solve the remainder of the problem (refer to the match editorial for details). We thus need a list of all n-bit integers which do not have two adjacent 1 bits, and we also need to know how many 1 bits there are in each such row. Here is my code for this: for (int i = 0; i < (1 << n); i++) { if (i & (i << 1)) continue; pg.push_back(i); pgb.push_back(__builtin_popcount(i)); }

Federal monitor says NYCHA not doing enough to remove mold and lead
by Danielle LeighNEW YORK (WABC) -- NYCHA isn't making enough progress to reduce issues with lead based paint and mold inside city housing, according to a report released late Friday afternoon by the federal monitor assigned to oversee reforms at the struggling city agency.
The report recognized that NYCHA has made progress toward spending state funding intended for new elevators and boilers.
The agency has also begun structural changes to better respond to residents needs going forward.
This is the second report the monitor has released since being assigned to oversee the agency earlier this year as part of an agreement with the federal government.

Setting up a sharded RethinkDB cluster on Ubuntu and Debian, NoSQL
Set Up a Sharded RethinkDB Cluster - Ubuntu, Debian
Difficulty: 3
Time: 30 minutes
RethinkDB, a NoSQL database, is the first open-source, scalable JSON database built from the ground up for real-time web applications. It's designed specifically to push data to applications in real time, dramatically reducing the time and effort necessary to build scalable real-time applications. In this article, we'll help you build a RethinkDB cluster, import a database onto it, and make it secure.
For these tasks, you'll need two servers running Ubuntu 14.04 or Debian 7, named rethinkdb1
and rethinkdb2
. For optimal security, set up a sudo
user for each RethinkDB server.
Set up a RethinkDB node
RethinkDB cluster is a type of peer-to-peer network. The primary step in building a RethinkDB cluster is to install RethinkDB on every server included in this cluster.
- On each server, add the RethinkDB key and repository to
apt-get
.
source /etc/lsb-release && echo "deb http://download.rethinkdb.com/apt
$DISTRIB_CODENAME main" | sudo tee /etc/apt/sources.list.d/rethinkdb.list
wget -qO- http://download.rethinkdb.com/apt/pubkey.gpg | sudo apt-key add –
- Update and install RethinkDB.
sudo apt-get update
sudo apt-get install rethinkdb
RethinkDB is installed on the server.
- Configure RethinkDB to run on startup.
sudo cp /etc/rethinkdb/default.conf.sample
/etc/rethinkdb/instances.d/cluster_instance.conf
sudo vi /etc/rethinkdb/instances.d/cluster_instance.conf
- Change the server name as follows:
Search for:
server-name=server
Change it to:
Server-name=rethinkdb1
- Set up the bind address.
By default it is accessible only on localhost (<IP_ADDRESS>). Change this so that it listens on all network interfaces.
Search for:
bind=<IP_ADDRESS>
Change it to:
Bind=all
- Save the configuration changes.
- Start RethinkDB with a new build configuration.
sudo service rethinkdb start
sudo netstat -tulnp | grep rethindb
The output looks like this:
tcp6 0 0 :::28016 :::* LISTEN 2181/rethinkdb
tcp6 0 0 :::8080 :::* LISTEN 2181/rethinkdb
tcp6 0 0 :::29015 :::* LISTEN 2181/rethinkdb
Secure the RethinkDB cluster
You've now configured RethinkDB to listen on all network interfaces (bind=all
). However, this exposes RethinkDB to outside networks and presents a security threat. In this section we'll make RethinkDB accessible only from authorized computers.
In the above netstat
command results, you see three different ports on which RethinkDB listens:
- Port 8080 is used for the RethinkDB web management console.
- Port 28015 is the driver port.
- Port 29015 is the cluster port.
We'll secure the cluster port through the firewall, and we'll use SSH tunnels to securely access the web management console and the driver port.
- Block all outside connections. Perform the following steps on all RethinkDB servers.
Web Management Console:
sudo iptables -A INPUT -i eth0 -p tcp --dport 8080 -j DROP
sudo iptables -I INPUT -i eth0 -s <IP_ADDRESS> -p tcp --dport 8080 -j ACCEPT
Driver Port:
sudo iptables -A INPUT -i eth0 -p tcp --dport 28015 -j DROP
sudo iptables -I INPUT -i eth0 -s <IP_ADDRESS> -p tcp --dport 28015 -j ACCEPT
Cluster Port:
sudo iptables -A INPUT -i eth0 -p tcp --dport 29015 -j DROP
sudo iptables -I INPUT -i eth0 -s <IP_ADDRESS> -p tcp --dport 29015 -j ACCEPT
- Install
iptables-persistent
to save the rules.
sudo apt-get install iptables-persistent
<Screnshot: 18528-iptables_save>
- At the prompt, select (yes) to save ipv4 and ipv6 rules.
Set up a management user
Next we need to set up SSH tunnels to access RethinkDB's web management console and the driver interface securely.
- Create a management user for SSH tunnel in
rethinkdb1
sudo adduser sshuser
- Set up the authorized keys file for a new user.
sudo mkdir /home/sshuser/.ssh
sudo touch /home/sshuser/.ssh/authorized_keys
- Import the public key from a local computer, from where you'll access the RethinkDB web management console. You can either copy the public key directly from your computer, or you can use
ssh-copy-id
command.
- Copy the user public key.
- Open
authorized_keys
for editing.
sudo vi /home/sshuser/.ssh/authorized_keys
- Paste the user public key into this file.
- Repeat the above steps to create other cluster nodes.
Import or create a database
If you already have a database on this or another server, you need to import those databases into your cluster. If there is no database, RethinkDB creates an empty database by default.
- Copy the database that you want to import on
rethinkdb1
, if not already present. First you need to find the path of your current RethinkDB database. (If you used the rethinkdb
command to start your old database, then the directory path is rethinkdb_data.)
Use the scp
command to copy it to rethinkdb1
sudo scp -rpC From Server User@From Server IP:/RethinkDB Data Folder/*
/var/lib/rethinkdb/cluster_instance/data
- Restart RethinkDB.
sudo service rethinkdb restart
- If you have an existing RethinkDB database on
rethinkdb1
, open the configuration file on rethinkdb1
sudo vi /etc/rethinkdb/instances.d/cluster_instance.conf
- Find the path of the RethinkDB database to import. If you used the
rethinkdb
command to start your old database, the directory is rethinkdb_data
. Insert that path into the configuration file.
directory=/home/user/rethink/rethinkdb_data/
- Save the changes.
- Restart RethinkDB.
sudo service rethinkdb restart
Create a cluster
- To create a cluster, first allow all cluster machines to be accessed through each other’s firewall. Now on
rethinkdb1
server, we will allow all other servers to connect to cluster port through firewall.
sudo iptables -I INPUT -i eth0 -s other_server_ip_address -p tcp --dport 29015 -j ACCEPT
- Repeat the same command for any other nodes you want to add. Replace
other_server_ip_address
with respective server IP addresses.
- Save the firewall changes.
sudo sh -c "iptables-save > /etc/iptables/rules.v4"
- Repeat these steps for your other servers.
Once ports are opened and servers can communicate to one another, you can connect other servers to create a cluster.
- To connect other servers, access the
rethinkdb2
server, and edit the following configuration file:
sudo vi /etc/rethinkdb/instances.d/cluster_instance.conf
- Join this server (rethinkdb2) to the cluster: Find the
join
statement in the file.
join=example.com:29015
Replace it with the following:
join=rethinkdb1_IP
- Save the configuration file, and then restart RethinkDB.
sudo service rethinkdb restart
- Perform the same steps for other servers.
In the first node, rethindb1 does not need a join
statement as we are joining other servers to rethinkdb1.
After completing this step, you have all servers joined to rethinkdb1 and have a fully functioning RethinkDB cluster.
Connect to the web management console
You can use the RethinkDB web management console for an online platform to perform basic functions on RethinkDB such as creating databases and tables, changing basic table settings, and running RethinkDB commands.
Connect to the cluster using Python driver
In this section we'll use a SSH tunnel to establish a connection with the driver port. Because we already have secured the connection to the cluster nodes, no one from outside the network can access the cluster port.
Now we'll create a SSH tunnel from one of the servers (rethinkdb2
), so that they can establish a secure connection to the cluster port (29018).
- Perform following steps in
rethinkdb2
to generate a SSH key.
ssh-keygen -t rsa
- Copy the public key (
id_rsa.pub
) to rethinkdb1 server (Cluster Node), and add in authorized_keys
.
sudo vi /home/sshuser/.ssh/authorized_keys
- Use SSH tunneling to access the driver port from the sever.
ssh -L 28015:localhost:28015 sshuser@cluster_node_ip -f -N
If you get a "bind: Address already in use error," you can change the port.
Eg: ssh -L 28016:localhost:28015 sshuser@cluster_node_ip -f –N
Install the Python driver
- To install the Python driver on the connecting server (
rethinkdb2
), install the Python virtual environment.
sudo apt-get install python-virtualenv
- Create a directory named
rethink
in user home directory.
mkdir rethink
cd rethink
- Create the new virtual environment structure.
virtualenv venv
- Activate the environment before starting Python.
source venv/bin/activate
- Install the RethinkDB module.
pip install rethinkdb
- Start Python from the connecting server.
Python
- Connect to the cluster server database. Make sure to provide the correct port, which you used earlier to connect to the SSH tunnel.
import rethinkdb as r
r.connect("localhost", 28016).repl()
- Create a table test.
r.db("test").table_create("test").run()
- Insert data into the table test.
r.db("test").table("test").insert({"hello":"world"}).run()
r.db("test").table("test").insert({"This”:”Is”:”world”}).run()
Sharding
RethinkDB allows you to shard and replicate your cluster on a per-table basis. You can control the sharding settings through web management console.
When using the web management console, you can perform sharding simply by specify the number of shards you want and based on the data available, RethinkDB will determine the best split points to maintain balanced shards. To shard your data:
- Go to the table view (Tables → table name).
- Click on the Reconfigure button.
- Set the number of shards and replicas you want.
- Click on the Apply Configuration button.
In addition to the options in web management console, ReQL
commands for table configuration allow both scripting capability and replication, distributing replicas for individual tables across user-defined groups of servers using server tags. All these functionalities can be achieved through ReQL
command.
There are three primary commands for changing sharding and replication in ReQL:
table_create
: Specify initial values of shards and replicas.
reconfigure
: Change the values of shards and replicas.
rebalance
: Used to rebalance table shards.
Advanced configuration
These include advanced configuration which cannot be performed through the web interface.
Server tag
- All servers in a RethinkDB cluster may be given zero or more tags that can be used in table configurations. This is used to map replicas to servers specified by tags. We can set a tag through the below command:
rethinkdb --server-tag us --server-tag us_west
- If no tags are specified on startup, the server will be started with default tag (default). When servers are tagged, you can use the tags in the reconfigure command:
- If we want to assign three replicas of the user's table to
us_1
and two to us_2
, use the following command:
r.table('users').reconfigure(shards=2, replicas={'us_1':3,
'us_2':2}, primary_replica_tag='us_2').run(conn)
Write acknowledgements and durability
Write acknowledgements and write durability are two other settings that can't be configured or managed through the web management console or reconfigure
command. They can be configured only by editing table table_config
for each individual table.
The write acknowledgement setting for a table controls when the cluster acknowledges a write
request as completed. There are two possible settings:
majority:
The cluster sends the acknowledgement when the majority of replicas have acknowledged it. This is the default.
single:
The cluster sends the acknowledgement when any replica has acknowledged it.
Below is an example:
r.db('rethinkdb').table('table_config').get(
'31c92680-f70c-4a4b-a49e-b238eb12c023').update(
{"write_acks": "single"}).run(conn)
The durability setting for a table controls when writes are committed. They include both hard and soft mode:
- In hard mode, writes are committed to disk before acknowledgements are sent
- In soft mode, writes are acknowledged immediately upon receipt. This is much faster.
Remove a server
Removing a server from the cluster must be performed carefully. When a document is divided over multiple servers, one server always keeps its primary index. If the server holding the primary index of the document is taken offline, then the document is lost. Therefore, before removing a server, you need to migrate all its primary shards away from it.
Here we'll migrate data off the node rethinkdb2
to make rethinkdb1
the sole node. Then we can remove the rethindb2
node safely.
- Enter the RethinkDB admin shell on
rethinkdb1.
rethinkdb admin
- List the shards (groups of documents) that
rethinkdb2
holds.
ls rethinkdb2
- Move the shards from one server (
rethinkdb2
) to another (rethinkdb1
).
pin shard TABLE SHARD-RANGE --master MACHINE-NAME
Eg : pin shard food.foodshards -inf-+inf --master rethinkdb1
- Exit from the admin shell.
Exit
Now you can safely stop RethinkDB on the server (rethinkdb2
).
- Execute this command in
rethinkdb2
:
sudo service rethinkdb stop
After you remove this server (rethinkdb2
), you receive a warning message when accessing the RethinkDB web management console. On the right-hand side of the message is a permanent remove button. You can click this button to remove this server (rethinkdb2
) from the cluster.
Conclusion
In this article, we discussed the steps involved in setting up a sharded RethinkDB cluster on Ubuntu and Debian servers.

As mentioned on the front page, this is an experiment to better understand the unique characteristics of blockchain technology, and how it might used to address challenges that are not served by conventional databases and web servers.
Volunteers deserve to be recognized in perpetuity. On the blockchain the records of volunteer contributions are resilient.
For Volunteer OrganizationsBecause many volunteer organizations and/or recognition initiatives come and go, and the new ones don't get the chance to build upon the successes of the past when an organization dissolves or stops paying its bills.
For CalgaryCalgary is famous for its volunteer spirit, and all Calgarians deserve to be recognized and proud of this fact. This registry will help tell that story across the world and for future generations, and will hopefully encourage more people to step up and do great things for their community.
Heck no. This is a very early, not ready for primetime, proof of concept for a 'distributed app' to share information with permanent storage and open access. It consists of a smart contract to store data on the ethereum blockchain and a web interface to interact with it.
The contract address is on the Rinkeby Test Network 0x8b963ede1E20d93eC2d73afaB54368F07DE0d382
The source code for the smart contract and the web interface is available on github.
