This course is a work in progress, so any feedback/suggestions are appreciated.


CMake is a Makefile generator. CMake will scan your source code and, based on some predefined rules,
generate Make
scripts. Using Cmake is a two-step process: first generate the Makefiles,
then compile your code by invoking Make
on the Makefiles. CMake documentation can be
found on cmake.org
Make is a much older tool that will, at its core, incrementally compile your code. This simply means that
if
you have a project with two files (cat.c
and dog.c
), and a change is made to
cat.c
, then only cat.c
will be re-compiled. Lots of different flavors of Make
have been developed over the years including GNU, MinGW, Ninja, and more - but we will focus on GNU
since
that is what ships with the Windows version of PropGCC and comes with most Linux operating systems.
GNU's
Make documentation can be found on
gnu.org.
Two command line instructions are all you need to get started:
cmake -G "Unix Makefiles" <source directory>
make
Breakdown:
cmake -G "Unix Makefiles" <source directory>
: Here we perform the
first
step - generating the Makefiles. CMake will scan your source directory, read your source files
to
discover dependencies (like header files), and create one or more files named “Makefile”.
The first argument, -G "Unix Makefiles"
, tells CMake exactly what flavor
of
Make we're using. As reasoned in the What is Make?
section above, we will always be
using Unix Makefiles
for PropWare projects.
The second argument is the source directory of your project. This directory must contain a
CMakeLists.txt
file as described in step 1 of
Creating a PropWare
Application. I prefer to run “out of source” builds - which means I create a new folder
within my project where all of my generated and compiled files will end up. Generally, I name
this
folder bin
. With this simple case, the complete command to generate the Makefiles
would be cmake -G "Unix Makefiles" ..
. The ..
is a
cross-platform way of saying “the directory above me”. For reference: .
refers to
the current directory.
make
: Make is old, flexible, and great. CMake has done all the work though and no
extra
arguments are needed for this command. After successfully running CMake, simply type make
- character for character. When it completes successfully, your project will have been
compiled into its binary format, ready to be programmed to your Propeller. %PropWare provides
some extra “targets” to make your life even easier though. Try typing make debug
to
write your program to RAM and open a terminal (like Parallax's PST) or make run
to
write your program to EEPROM.
As described in Chapter 4, the CMakeLists.txt file is required for all CMake (and therefore %PropWare) applications. The file must be named “CMakeLists.txt” - character for character.
The contents of the file are simple - many useful tips can be gleaned from both Creating a PropWare Application and CMake for PropWare.
I won't hold back - CMakeCache.txt can be a royal pain. CMake keeps track of your settings in this file
and,
a lot of times, you might change a setting without CMake taking notice. When this happens, just delete
the
CMakeCache.txt
file and rerun your CMake command (as given above). As a bonus to using the
out-of-source build technique you can also just delete your entire build directory and start over - then
you know with 100% confidence that no leftover settings will linger around to haunt you.
Curses is a library that provides a psuedo-graphical user interface at the command line. Curses CMake (or
ccmake) allows you to easily configure some options for your project before compiling it. Try running
ccmake -G "Unix Makefiles <source directory>
next time and take a look.
A make “target” is a set of commands that you would like Make to execute for you. If you run Make with no
arguments, a default target of “all” is chosen for you. Generally, the all
target will
compile your code. On the rare off-chance that you made some changes to your code and Make hasn't picked
them up (and therefore is not recompiling them), giving Make the “clean” target will delete all compiled
objects and let you start over (make clean
). You can remove old files and recompile new
ones
in a single step with make clean all
(order matters).
PropWare provides two extra targets for your convenience.
debug
target will compile your code, write it to your Propeller's HUB RAM and then
start a serial terminal to
aid in debugging your application. When you are finished, press any of the arrow keys on your
keyboard
(don't use
Control-C
- it doesn't seem to like that) and you will be returned to your normal
command
prompt.
run
target will compile your code and load it into your Propeller's EEPROM.After generating your Makefiles, try adding VERBOSE=1
to your Make command. This will tell
Make
to print each command to the terminal before running it - rather than printing only a short summary of
what is being done. The output is very verbose and can be cumbersome to read - but it is invaluable when
determining what went wrong with your compilation. Full command: make VERBOSE=1

execline
Software
skarnet.org
The execline-umask program
execline-umask sets the umask (file creation mask),
then executes a program.
Interface
execline-umask mask prog...
execline-umask sets the current umask to mask,
then execs into prog....
Notes
- By default, at execline installation time, a umask
symbolic link is created, pointing to execline-umask.
- When execline has been configured with the --enable-pedantic-posix
option, the umask symbolic link points to the
posix-umask binary instead.
- Existing execline scripts calling umask will keep working
no matter the chosen configuration.

UserMsg Pile
version 0.0.1
UserMsg pile.
|
The UserMsg class provides a way to manage and dispatch messages that are intended for the user. The library does not provide the GUI to actually show the messages. Instread, a callback mechanism is employed and the user is expected to provide necessary callbacks. Also, the Qt signal/slot mechanism is also used, so the user has some flexibility in implementing the front-end.
UserMsgMan is the manager class. A singleton is created internally and it manages the settings and behaviour of UserMsg. The manager can be explicitly initialized but it does not have to. Any static function that will be invoked will first check for its existance and it will create it if it does not exist. Resources can be freed using UserMsgMan::end(), for example at the end of the application.
The messaging system can be disabled temporarly by calling UserMsgMan::disable(). It will accumulate the messages internaly and show them when UserMsgMan::enable() is called. The messages can be collapsed into one per type.
An initialization sequence that makes use of all the features of the manager may look like so:
The frontend has a range of options to connect and use the library.
Following callbacks are available:
Following signals are available:
A message consists of an optional title, an optional user defined value (payload) and a list of zero or more entries.
Each entry consists of a timestamp, a type and a message.
The informative messages are errors, warnings and general information that is intended to the user. The user is only informed about the event and, depending on the GUI front-end, may need to confirm message acknowledgement.
A message can be shown right away:
Messages can be accumulated in an instance of the class and presented later (or never presented):
To show the content accumulated in the structure, if any, use:
This will present the user with the messages the user elected to see.

This is a story of my first and only trip on acid. I was with my friend Mike at a party getting drunk, popping pills and waiting for a bag of weed to arrive. When the weed didn't show up at midnight me and Mike took his truck to go and find a bag. Mike said that his roommate Matt could probably find some. When we got to Mike's dormroom Matt was just about to leave to another party.
'Got any buds?' I asked.
Matt said he didn't have any and he didn't know where to get any but for fifty bucks he'd run and get me 14 hits of acid.
When Matt returned he handed me a piece of foil with a strip of tie-dye paper wrapped inside it. Mike (who had tripped alot before) cut it and gave me a tab of paper amounting to about six hits. I asked Matt how much I should do and he said 'for the first time? I'd take one-maybe two.' I put the entire cut on my tongue 'if one or two will get me tripping, six will make me trip balls' I thought. 'great, now what am I supposed to do?' Mike asked (he had intended on splitting 3 a peice). “take the rest, it'll be fun!” I said. Mike took the remaining eight hits and we headed to the grocery store for some snacks and orange juice.
Mike and me had been planning on tripping together ever since we met. We had taken laundry detergent and black lights and turned his room into a tripper's paradise. When the lights were off and the black lights were on the tide that was flung all over the room would glow like a giant world of stars and as we started our trip, the setting couldn't have been any more comfortable.
For about two hours all we did was sit there and watch this beautiful scene, it was great. Than we decided to go for a cigarette.
While outside, we ran into a pothead named Robert, he was smoking a joint, so we joined him right outside of the dorm doors, passing a doobie like it was legal.   He decided to give us a couple of joints to enhance our trip. We thanked him and went to Mike's truck and smoked both joints.
Mike's truck was so cloudy that I couldn't see him a foot away from me. We opened the doors and laughed as all the smoke bellowed out like a giant wave. To our horrored surprise, the campus police officer was just walking out of the door as we shut both doors.
Did he see us get high and is he coming to bust us?
we didn't know but anyone who's ever tripped will tell you that police are extremely negative to a trip.
Mike started to run but I grabbed him by the back of his shirt.
'He can't bust you if you stay cool.'

The cop passed us without even looking.
 I was still having a good time but the combination of Mike's frightened voice, the six hits, and the events just prior, finally sank in, it was no longer fun to be this fucked up, and I wanted out.
But I wasn't getting out, the music became more and more violent, all the shadows in the room stood out and began to crawl, the television light began to dim, and the music became evil, chanting voices, I didn't know what they were saying but I knew they were summoning Satan. The faces on the TV merged together and turned a brilliant color red, the red became an ominous face and that face grew ram horns and fiery yellow eyes, and breathed blasphemous fire right into my soul.
 I felt saved and very relieved. Me and Mike left his room and drove to a friend's house so he could calm down, his heart was beating a million times a minute, and he was very worried but eventually we both got sleep that night.
I have never done acid since than. For a year I was plagued with anxiety attacks, probably post-traumatic stress syndrome from what had happened. Mike too experienced negative reactions.
Since then I have come to the conclusion that the devil was a hallucinative manifestation of my depression, since that trip I quit popping pills, getting drunk, and only smoke weed occasionally. One might think my experience was negative, but I believe that LSD is a tool that showed me who I really was, and helped me change my life for the better. It also taught me to respect drugs and also myself, since my experience I have changed many of the negative things about me. And I couldn't have done it without the help of my own demons.

Permanent storage is something most applications want to have in one way or another. Selecting the right storage wouldn't be a choice at all if there weren't so many options out there, and a lot of these come with their respective advantages and disadvantages.
The process in principle is always going to be the same:
- Figure out what we need, in a technical and a user experience sense
- Figure out which options could fit our design
- Compare these two sets and select accordingly
So the first step in figuring out what the correct storage option for our application is, is figuring out what our application is. Without knowing what our application is going to need, we can't make an informed decision about which path to take.
Requirements
Sealas is at the stage where this question becomes relevant, and so we'll take it as an example. The user database is already done, and is using a simple single schema Postgres database. The application data is where it gets interesting.
We have two unique properties of our application we need to take into consideration:
- All our application data is being encrypted on the client before it reaches storage
- We want to have an Offline First application
Client-side encryption
One of our goals is to provide a privacy focused application, so our users don't need to worry about any side effects of using a web application. This would include possible leaks, possible surveillance or any other data aggregation methods.
Storage wise this means all incoming data is opaque. We can't manipulate it and we can't look at it. Another thing we can't do, is forget that we have other goals as well: the biggest of them is a good user experience. One of the most recognizable aspects of a good user experience is speed, so one of the trade-offs necessary here is with metadata.
Just because we don't want to look at the actual contents, doesn't mean we can't employ the help of relational data to make searching and selective access easier. Without any meta data, the only available method for searching left would be to always download all data on the client, which would have a significant performance impact.
Offline First
Offline First may seem like a buzzword just thrown around to make us feel good.
Without a closer look at what we actually mean to do with it, this remains true. Again, this is not purely a technical feature, but one that is very much focused on our user experience design. In principle it just means we want to save all data locally before pushing it into some kind of messaging queue to sync it back to the server.
So what do we want to achieve by adding this capability?
There are two aspects that are most relevant here: keeping our data in sync when the connection becomes flaky, and providing us with the option for an amazing onboarding experience. Let's have a closer look:
#### Connections
Flaky connections are not only an issue with a moody router or a roommate who all of a sudden decides to download the entire internet. If at any point we want to expand our web application to serve mobile users as well, we reach an entirely different realm of constantly dropping connections. Having a working data sync ready however allows us to keep working with the same code base.
With a growing set of options to implement mobile apps with JavaScript like NativeScript for Angular and Vue.JS, or React Native, this is something to keep in mind.
User experience wise this also enables something crucial: saving user input across sessions. So even if the browser decides to crash in just the right moment, all work done remains in the browser. Nothing ruins a day more than finding out the hard way that your app doesn't do automated backups of your work.
#### Onboarding
One of the things I want to build and would love to see more often is a seamless transition between demoing a product and actively working with it. Offline First in this case enables us to give the user a clean new working environment to try out the application with their actual data and use-cases, and if they happen to like it, they can create an account to which we can sync the existing data.
Datastore options
Now that we know what we're dealing with, let's look at the available options.
Postgres with a multi tenant setup
Since Sealas' backend runs with Elixir and Phoenix, whose default supported database is Postgres, this would be the most natural choice when going for a RDBMS. We didn't rule out relational data after all, so it makes sense to include it as a viable option.
Other advantages of using Postgres:
- Very stable and mature product
- Big community and support base around it
- Rich "NoSQL" data support with HStore and JSON support
Schematic scalability is not that much of an issue for us, since at least the bulk of our data is going to a simple blob whose structure would be changed client-side anyway.
Postgres with a multi instance setup
Same argumentation as above with one key difference: every user would get their own database. Having a multi instance setup allows us to completely separate data at a user level. This would allow us to easily add features for each individual user with their own structure. We could also include stricter ACLs for added security.
Our users' data is encrypted though, so it's not that much of a concern as it would be otherwise. Apart from that, the setup and maintenance is also a bit more complicated, especially with updates, since every database would need to have their migrations run separately.
CouchDB (+ PouchDB)
PouchDB is the ready-made solution for Offline First support that an implementation with Postgres would be lacking. It provides you with a database on the browser, which syncs back to a CouchDB instance.
In CouchDB terms, a connection between two databases is a sync — but at the same time it can also be unidirectional to serve as a backup. On the server-side this would make backups absolutely trivial.
PouchDB even sports backwards compatibility for almost any more modern browser. One of the things that worries me about this option though, is that it's a very niche project that doesn't have a lot of traction.
Decisions, decisions
CouchDB may seem like the ideal candidate, when focusing only on the sync aspect. But then again there's no such thing as free lunch and every good thing also has its downsides. The easiest one to point out is that it would make for a heavier tech stack.
Couch also wants to be your application server, which is even more true in combination with Pouch, as it wants to speak directly to the database. So if you already have an authentication system in place, this might become a pain to integrate.
Postgres on the other hand doesn't have a widespread solution for Offline First support ready-made to just plug in and play. There is however one new addition to the world of web development that is getting more and more mature: Service Workers; background scripts that act as proxies between your app and the server, which can access the IndexedDB API for caching.
Another big plus for a stack with Postgres, is my own level of experience with running applications backed by an RDBMS. Experience building things usually results in more robust code but especially something that gets done way quicker. Then again, you lose out on learning something new.
In the end pondering only gets you so far, and the one thing that will get things done the easiest is tossing a coin or experimenting with a few prototypes. We would need to find out how easily possible it is to integrate Pouch+Couch into an existing application design and how easy it is to make changes to the way data is saved and partitioned. If that proves too much work, Postgres wins again.


This document covers setting up and managing authentication and authorization in InfluxDB.
| Authentication: | Authorization: |
| Set up Authentication | User Types and Privileges |
| Authenticate Requests | User Management Commands |
| HTTP Errors | HTTP Errors |
Note: Authentication and authorization should not be relied upon to prevent access and protect data from malicious actors. If additional security or compliance features are desired, InfluxDB should be run behind a third-party service.
Authentication
The InfluxDB API and the command line interface (CLI), which connects to the database using the API, include simple, built-in authentication based on user credentials. When you enable authentication, InfluxDB only executes HTTP requests that are sent with valid credentials.
Note: Authentication only occurs at the HTTP request scope. Plugins do not currently have the ability to authenticate requests and service endpoints (for example, Graphite, collectd, etc.) are not authenticated.
Set up authentication
1. Create at least one admin user.
See the authorization section for how to create an admin user.
Note: If you enable authentication and have no users, InfluxDB will not enforce authentication and will only accept the query that creates a new admin user.
InfluxDB will enforce authentication once there is an admin user.
2. By default, authentication is disabled in the configuration file.
Enable authentication by setting the auth-enabled
option to true
in the [http]
section of the configuration file:
[http]
enabled = true
bind-address = ":8086"
auth-enabled = true # ✨
log-enabled = true
write-tracing = false
pprof-enabled = true
pprof-auth-enabled = true
debug-pprof-enabled = false
ping-auth-enabled = true
https-enabled = true
https-certificate = "/etc/ssl/influxdb.pem"
If pprof-enabled
is set to true
, set pprof-auth-enabled
and ping-auth-enabled
to true
to require authentication on profiling and ping endpoints.
3. Restart the process
Now InfluxDB will check user credentials on every request and will only process requests that have valid credentials for an existing user.
Authenticate requests
Authenticate with the InfluxDB API
There are two options for authenticating with the InfluxDB API.
If you authenticate with both Basic Authentication and the URL query parameters, the user credentials specified in the query parameters take precedence. The queries in the following examples assume that the user is an admin user. See the section on authorization for the different user types, their privileges, and more on user management.
Note: InfluxDB redacts passwords when you enable authentication.
Authenticate with Basic Authentication as described in RFC 2617, Section 2
This is the preferred method for providing user credentials.
Example:
curl -G http://localhost:8086/query -u todd:influxdb4ever --data-urlencode "q=SHOW DATABASES"
Authenticate by providing query parameters in the URL or request body
Set u
as the username and p
as the password.
Example using query parameters
curl -G "http://localhost:8086/query?u=todd&p=influxdb4ever" --data-urlencode "q=SHOW DATABASES"
Example using request body
curl -G http://localhost:8086/query --data-urlencode "u=todd" --data-urlencode "p=influxdb4ever" --data-urlencode "q=SHOW DATABASES"
Authenticate with the CLI
There are three options for authenticating with the CLI.
Authenticate with the INFLUX_USERNAME
and INFLUX_PASSWORD
environment variables
Example:
export INFLUX_USERNAME=todd
export INFLUX_PASSWORD=influxdb4ever
echo $INFLUX_USERNAME $INFLUX_PASSWORD
todd influxdb4ever
influx
Connected to http://localhost:8086 version 1.4.x
InfluxDB shell 1.4.x
Authenticate by setting the username
and password
flags when you start the CLI
Example:
influx -username todd -password influxdb4ever
Connected to http://localhost:8086 version 1.4.x
InfluxDB shell 1.4.x
Authenticate with auth <username> <password>
after starting the CLI
Example:
influx
Connected to http://localhost:8086 version 1.4.x
InfluxDB shell 1.4.x
> auth
username: todd
password:
>
Authenticate using JWT tokens
Passing JWT tokens in each request is a more secure alternative to using passwords. This is currently only possible through the InfluxDB HTTP API.
1. Add a shared secret in your InfluxDB configuration file
InfluxDB uses the shared secret to encode the JWT signature.
By default, shared-secret
is set to an empty string, in which case no JWT authentication takes place.
Add a custom shared secret in your InfluxDB configuration file.
The longer the secret string, the more secure it is:
[http]
shared-secret = "my super secret pass phrase"
Alternatively, to avoid keeping your secret phrase as plain text in your InfluxDB configuration file, set the value with the INFLUXDB_HTTP_SHARED_SECRET
environment variable.
2. Generate your token
Use an authentication service to generate a secure token using your InfluxDB username, an expiration time, and your shared secret. There are online tools, such as https://jwt.io/, that will do this for you.
The payload (or claims) of the token must be in the following format:
{
"username": "myUserName",
"exp":<PHONE_NUMBER>
}
◦ username - The name of your InfluxDB user.
◦ exp - The expiration time of the token in UNIX epoch time.
For increased security, keep token expiration periods short.
For testing, you can manually generate UNIX timestamps using https://www.unixtimestamp.com/index.php.
Encode the payload using your shared secret. You can do this with either a JWT library in your own authentication server or by hand at https://jwt.io/. The generated token should look similar to the following:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.he0ErCNloe4J7Id0Ry2SEDg09lKkZkfsRiGsdX_vgEg
3. Include the token in HTTP requests
Include your generated token as part of the Authorization
header in HTTP requests.
Use the Bearer
authorization scheme:
Authorization: Bearer <myToken>
Only unexpired tokens will successfully authenticate. Be sure your token has not expired.
Example query request with JWT authentication
curl -XGET "http://localhost:8086/query?db=demodb" \
--data-urlencode "q=SHOW DATABASES" \
--header "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.he0ErCNloe4J7Id0Ry2SEDg09lKkZkfsRiGsdX_vgEg"
Authenticate Telegraf requests to InfluxDB
Authenticating Telegraf requests to an InfluxDB instance with
authentication enabled requires some additional steps.
In the Telegraf configuration file (/etc/telegraf/telegraf.conf
), uncomment
and edit the username
and password
settings.

timeout = "5s"
username = "telegraf" #💥
password = "metricsmetricsmetricsmetrics" #💥
>
[...]
Next, restart Telegraf and you’re all set!
Authorization
Authorization is only enforced once you’ve enabled authentication. By default, authentication is disabled, all credentials are silently ignored, and all users have all privileges.
User types and privileges
Admin users
Admin users have READ
and WRITE
access to all databases and full access to the following administrative queries:
Database management:
◦ CREATE DATABASE
, and DROP DATABASE
◦ DROP SERIES
and DROP MEASUREMENT
◦ CREATE RETENTION POLICY
, ALTER RETENTION POLICY
, and DROP RETENTION POLICY
◦ CREATE CONTINUOUS QUERY
and DROP CONTINUOUS QUERY
See the database management and continuous queries pages for a complete discussion of the commands listed above.
User management:
◦ Admin user management:
CREATE USER
, GRANT ALL PRIVILEGES
, REVOKE ALL PRIVILEGES
, and SHOW USERS
◦ Non-admin user management:
CREATE USER
, GRANT [READ,WRITE,ALL]
, REVOKE [READ,WRITE,ALL]
, and SHOW GRANTS
◦ General user management:
SET PASSWORD
and DROP USER
See below for a complete discussion of the user management commands.
Non-admin users
Non-admin users can have one of the following three privileges per database:
◦ READ
◦ WRITE
◦ ALL
(both READ
and WRITE
access)
READ
, WRITE
, and ALL
privileges are controlled per user per database. A new non-admin user has no access to any database until they are specifically granted privileges to a database by an admin user.
Non-admin users can SHOW
the databases on which they have READ
and/or WRITE
permissions.
User management commands
Admin user management
When you enable HTTP authentication, InfluxDB requires you to create at least one admin user before you can interact with the system.
 If any values change the database will return a duplicate user error. See GitHub Issue #6890 for details.CLI example:
> CREATE USER todd WITH PASSWORD '123456' WITH ALL PRIVILEGES > CREATE USER todd WITH PASSWORD '123456' WITH ALL PRIVILEGES > CREATE USER todd WITH PASSWORD '123' WITH ALL PRIVILEGES ERR: user already exists > CREATE USER todd WITH PASSWORD '123456' ERR: user already exists > CREATE USER todd WITH PASSWORD '123456' WITH ALL PRIVILEGES >
GRANT
administrative privileges to an existing user
GRANT ALL PRIVILEGES TO <username>
CLI example:
> GRANT ALL PRIVILEGES TO "todd"
>
REVOKE
administrative privileges from an admin user
REVOKE ALL PRIVILEGES FROM <username>
CLI example:
> REVOKE ALL PRIVILEGES FROM "todd"
>
SHOW
all existing users and their admin status
SHOW USERS
CLI example:
> SHOW USERS
user admin
todd false
paul true
hermione false
dobby false
Non-admin user management
CREATE
a new non-admin user
CREATE USER <username> WITH PASSWORD '<password>'
CLI example:
> CREATE USER todd WITH PASSWORD 'influxdb41yf3'
> CREATE USER alice WITH PASSWORD 'wonder\'land'
> CREATE USER "rachel_smith" WITH PASSWORD 'asdf1234!'
> CREATE USER "monitoring-robot" WITH PASSWORD 'XXXXX'
> CREATE USER "$savyadmin" WITH PASSWORD 'm3tr1cL0v3r'
>
Notes:
- The user value must be wrapped in double quotes if it starts with a digit, is an InfluxQL keyword, contains a hyphen and or includes any special characters, for example:
!@#$%^&*()-
- The password string must be wrapped in single quotes.
- Do not include the single quotes when authenticating requests.
For passwords that include a single quote or a newline character, escape the single quote or newline character with a backslash both when creating the password and when submitting authentication requests.
- Repeating the exact
CREATE USER
statement is idempotent. If any values change the database will return a duplicate user error. See GitHub Issue #6890 for details.CLI example:
> CREATE USER "todd" WITH PASSWORD '123456' > CREATE USER "todd" WITH PASSWORD '123456' > CREATE USER "todd" WITH PASSWORD '123' ERR: user already exists > CREATE USER "todd" WITH PASSWORD '123456' > CREATE USER "todd" WITH PASSWORD '123456' WITH ALL PRIVILEGES ERR: user already exists > CREATE USER "todd" WITH PASSWORD '123456' >
GRANT
READ
, WRITE
or ALL
database privileges to an existing user
GRANT [READ,WRITE,ALL] ON <database_name> TO <username>
CLI examples:
GRANT
READ
access to todd
on the NOAA_water_database
database:
> GRANT READ ON "NOAA_water_database" TO "todd"
>
GRANT
ALL
access to todd
on the NOAA_water_database
database:
> GRANT ALL ON "NOAA_water_database" TO "todd"
>
REVOKE
READ
, WRITE
, or ALL
database privileges from an existing user
REVOKE [READ,WRITE,ALL] ON <database_name> FROM <username>
CLI examples:
REVOKE
ALL
privileges from todd
on the NOAA_water_database
database:
> REVOKE ALL ON "NOAA_water_database" FROM "todd"
>
REVOKE
WRITE
privileges from todd
on the NOAA_water_database
database:
> REVOKE WRITE ON "NOAA_water_database" FROM "todd"
>
Note: If a user with
ALL
privileges hasWRITE
privileges revoked, they are left withREAD
privileges, and vice versa.
SHOW
a user’s database privileges
SHOW GRANTS FOR <user_name>
CLI example:
> SHOW GRANTS FOR "todd"
database privilege
NOAA_water_database WRITE
another_database_name READ
yet_another_database_name ALL PRIVILEGES
one_more_database_name NO PRIVILEGES
General admin and non-admin user management
ReSET
a user’s password
SET PASSWORD FOR <username> = '<password>'
CLI example:
> SET PASSWORD FOR "todd" = 'influxdb4ever'
>
Note: The password string must be wrapped in single quotes. Do not include the single quotes when authenticating requests. For passwords that include a single quote or a newline character, escape the single quote or newline character with a backslash both when creating the password and when submitting authentication requests.
DROP
a user
DROP USER <username>
CLI example:
> DROP USER "todd"
>
Authentication and authorization HTTP errors
Requests with no authentication credentials or incorrect credentials yield the HTTP 401 Unauthorized
response.
Requests by unauthorized users yield the HTTP 403 Forbidden
response.

uni2ascii(1) uni2ascii(1) NAME uni2ascii - convert UTF-8 Unicode to various 7-bit ASCII representations SYNOPSIS uni2ascii [options] (<input file name>) DESCRIPTION uni2ascii converts UTF-8 Unicode to various 7-bit ASCII representations. If no format is specified, standard hexadecimal format (e.g. 0x00e9) is used. It reads from the standard input and writes to the standard out‐ put. Command line options are: -A List the single character approximations carried out by the -y flag. -a <format> Convert to the specified format. Formats may be specified by means of the following arbitrary single character codes, by means of names such as "SGML_decimal", and by examples of the desired for‐ mat. A Generate hexadecimal numbers with prefix U in angle-brackets (<U00E9>). B Generate \x-escaped hex (e.g. \x00E9) C Generate \x escaped hexadecimal numbers in braces (e.g. \x{00E9}). D Generate decimal HTML numeric character references (e.g. é) E Generate hexadecimal with prefix U (U00E9). F Generate hexadecimal with prefix u (u00E9). G Convert hexadecimal in single quotes with prefix X (e.g. X'00E9'). H Generate hexadecimal HTML numeric character references (e.g. é) I Generate hexadecimal UTF-8 with each byte's hex preceded by an =-sign (e.g. =C3=A9) . This is the Quoted Printable format defined by RFC 2045. J Generate hexadecimal UTF-8 with each byte's hex preceded by a %-sign (e.g. %C3%A9). This is the URI escape format defined by RFC 2396. K Generate octal UTF-8 with each byte escaped by a backslash (e.g. \303\251) L Generate \U-escaped hex outside the BMP, \u-escaped hex within the BMP (U+0000-U+FFFF). M Generate hexadecimal SGML numeric character references (e.g. \#xE9;) N Generate decimal SGML numeric character references (e.g. \#233;) O Generate octal escapes for the three low bytes in big-endian order(e.g. \000\000\351)) P Generate hexadecimal numbers with prefix U+ (e.g. U+00E9) Q Generate character entities (e.g. é) where possible, oth‐ erwise hexadecimal numeric character references. R Generate raw hexadecimal numbers (e.g. 00E9) S Generate hexadecimal escapes for the three low bytes in big- endian order (e.g. \x00\x00\xE9) T Generate decimal escapes for the three low bytes in big-endian order (e.g. \d000\d000\d233) U Generate \u-escaped hexadecimal numbers (e.g. \u00E9). V Generate \u-escaped decimal numbers (e.g. \u00233). X Generate standard hexadecimal numbers (e.g. 0x00E9). 0 Generate hexadecimal UTF-8 with each byte's hex enclosed within angle brackets (e.g. <C3><A9>). 1 Generate Common Lisp format hexadecimal numbers (e.g. #x00E9). 2 Generate Perl format decimal numbers with prefix v (e.g. v233). 3 Generate hexadecimal numbers with prefix $ (e.g. $00E9). 4 Generate Postscript format hexadecimal numbers with prefix 16# (e.g. 16#00E9). 5 Generate Common Lisp format hexadecimal numbers with prefix #16r (e.g. #16r00E9). 6 Generate ADA format hexadecimal numbers with prefix 16# and suf‐ fix # (e.g. 16#00E9#). 7 Generate Apache log format hexadecimal UTF-8 with each byte's hex preceded by a backslash-x (e.g. \xC3\xA9). 8 Generate Microsoft OOXML format hexadecimal numbers with prefix _x and suffix _ (e.g. _x00E9_). 9 Generate %\u-escaped hexadecimal numbers (e.g. %\u00E9). -B Transform to ASCII if possible. This option is equivalent to the combination cdefx. -c Convert circled and parenthesized characters to their unenclosed counterparts. -d Strip diacritics. This converts single codepoints representing characters with diacritics to the corresponding ASCII character and deletes separately encoded diacritics. -e Convert characters to their approximate ASCII equivalents, as fol‐ lows: U+0085 next line 0x0A newline U+00A0 no break space 0x20 space U+00AB left-pointing double angle quotation mark 0x22 double quote U+00AD soft hyphen 0x2D minus U+00AF macron 0x2D minus U+00B7 middle dot 0x2E period U+00BB right-pointing double angle quotation mark 0x22 double quote U+1361 ethiopic word space 0x20 space U+1680 ogham space 0x20 space U+2000 en quad 0x20 space U+2001 em quad 0x20 space U+2002 en space 0x20 space U+2003 em space 0x20 space U+2004 three-per-em space 0x20 space U+2005 four-per-em space 0x20 space U+2006 six-per-em space 0x20 space U+2007 figure space 0x20 space U+2008 punctuation space 0x20 space U+2009 thin space 0x20 space U+200A hair space 0x20 space U+200B zero-width space 0x20 space U+2010 hyphen 0x2D minus U+2011 non-breaking hyphen 0x2D minus U+2012 figure dash 0x2D minus U+2013 en dash 0x2D minus U+2014 em dash 0x2D minus U+2018 left single quotation mark 0x60 left single quote U+2019 right single quotation mark 0x27 right or neutral single quote U+201A single low-9 quotation mark 0x60 left single quote U+201B single high-reversed-9 quotation mark 0x60 left single quote U+201C left double quotation mark 0x22 double quote U+201D right double quotation mark 0x22 double quote U+201E double low-9 quotation mark 0x22 double quote U+201F double high-reversed-9 quotation mark 0x22 double quote U+2022 bullet 0x6F small letter o U+2028 line separator 0x0A newline U+2033 double prime 0x22 double quote U+2039 single left-pointing angle quotation mark 0x60 left single quote U+203A single right-pointing angle quotation mark 0x27 right or neutral single quote U+204E low asterisk 0x2A asterisk U+2212 minus sign 0x2D minus U+2216 set minus 0x5C back‐ slash U+2217 asterisk operator 0x2A asterisk U+2223 divides 0x7C vertical line U+2500 box drawing light horizontal 0x2D minus U+2501 box drawing heavy horizontal 0x2D minus U+2502 box drawing light vertical 0x7C vertical line U+2503 box drawing heavy vertical 0x7C vertical line U+2731 heavy asterisk 0x2A asterisk U+275D heavy double turned comma quotation mark 0x22 double quote U+275E heavy double comma quotation mark 0x22 double quote U+3000 ideographic space 0x20 space U+FE60 small ampersand 0x26 amper‐ sand U+FE61 small asterisk 0x2A asterisk U+FE62 small plus sign 0x2B plus sign -E List the expansions performed by the -x flag. -f Convert stylistic variants to plain ASCII. Stylistic equivalents include: superscript and subscript forms, small capitals (e.g. U+1D04), script forms (e.g. U+212C), black letter forms (e.g. U+212D), fullwidth forms (e.g. U+FF01), halfwidth forms (e.g. U+FF7B), and the mathematical alphanumeric symbols (e.g. U+1D400). -h Help. Print the usage message and exit. -l Use lowercase a-f when generating hexadecimal numbers. -n Convert newlines too. By default, they are left alone. -P Pass through Unicode rather than converting to ASCII escapes if the character is not converted to an ASCII character by a trans‐ formation such as diacritic stripping. Note that if this option is used the output may not be pure ASCII. -p Pure. Convert characters within the ASCII range except for space and newline as well as those above. -q Quiet. Do not chat unnecessarily while working. -s Convert space characters too. By default, they are left alone. -S <Unicode:ASCII> Define a custom substitution. The argument should consist of the Unicode codepoint to be replaced followed by the ASCII code of the character to be used as replacement, separated by a colon. If no ASCII code follows the colon, the specified Unicode character will be deleted. The code values may be in hexadecimal, octal, or dec‐ imal following the usual conventions (to be precise,those of str‐ toul(3)). This option may be repeated as many times as desired to define multiple substitutions. -v Print program version information and exit. -w Add a space after each converted item. -x Expand certain characters to multicharacter sequences.

Kerala govt moves HC against acquittal of accused in Walayar sisters death case
The state government sought a direction to call for the records of the case, set aside the sessions court judgment and convict the accused for the offences or order an investigation into the crime.
by PTIThe Kerala government on Wednesday filed an appeal in the high court, challenging the acquittal of the accused in the Walayar sisters’ death case, saying the lower court verdict was “absolutely perverse and wholly unsustainable.”
The state government sought a direction to call for the records of the case, set aside the sessions court judgment and convict the accused for the offences or order an investigation into the crime.
The government admitted that the police failed to conduct a foolproof investigation touching upon all areas, which should have been covered.
The move comes after the government announced in the state assembly that the public prosecutor who handled it has been removed and said a probe is on to identify lapses in the police inquiry, if any.
Chief Minister Pinarayi Vijayan had informed the state assembly that the government would go in for an appeal against the POCSO court order.
Two minor girls were found dead in Walayar. The elder child, aged 13, was found dead on January 13, 2017, and the younger child, aged nine, died 52 days later.

The single QR option is slightly more tricky to use, but could save more time. This video demonstrates how ti can be used.
This is very much in testing mode at the moment, for a busy clinic, I suggest sticking to the default option.
For this final step, add your CSV file containing your patient list. The file is not uploaded anywhere and is processed entirely within your web browser.
| Name | NHS Number | Date Of Birth | StartTime* | SessionDate* |
|---|---|---|---|---|
| Bloggs, Joe |<PHONE_NUMBER> | 12/01/1956 | 18:30 | 08/01/2021 |
*Optional
All fields except "StartTime" and "SessionDate" will be soft matched. This means the column names or date formats do not need to be exactly as above. Dates can be in any format.
Additional fields can be included but will be ignored.

Programmatic
We programmatically create transactions using ebeanServer.beginTransaction()
.
When we do so we generally should use try with resources
to ensure that the
transaction is closed regardless of an exception throw.
```java
// use try with resources such that the transaction is
// always closed, even if an exception is thrown
try (Transaction transaction = ebeanServer.beginTransaction()) {
// do good stuff...
customer.save();
order.save();
transaction.commit();
}
```

24 things that are considered ‘normal’ in the US but the rest of the world finds weird
by Jessica Booth- Some common practices in America are actually quite strange to people from other countries.
- America’s obsession with drug commercials, American flags, and taking leftover food home after a restaurant meal are odd to people from overseas.
- Other countries also don’t have the same tipping culture – or the same amount of student debt.
- Visit Insider’s homepage for more stories.
Sometimes people in the US forget that the way we do things isn’t necessarily the way it’s done everywhere else.
That doesn’t mean these American customs are bad – it just means that what we believe is common is actually not. Here are some regular things we do in the US that people from other cultures might think is a bit strange.
Using money that is all the same color.
It seems confusing.
NBC
In the US, dollar bills are all the same shade of green, and they all look very similar, aside from slightly different images.
If you travel to other countries, you’ll find that their bills are typically all different colors and sizes according to what they’re worth. Many foreigners find our currency to be a bit confusing, since it all looks the same.
Putting a lot of ice in our drinks.
One small thing that stands out when you visit Europe is that they don’t use a lot of ice – at most restaurants, you won’t get it unless you ask for it.
Americans are some of the only people who use an excess of ice in their drinks. Articles have even written about why we do it. The Smithsonian believes it may be related to our “more is more” vibe in the US.
Using “America” or “Americans” to describes ourselves, our customs, and our country.
If you grew up in the US, you may think of “America” and “United States” as interchangeable. As it turns out, much of the rest of the world does not.
The United States is not the only “America” out there – there’s also the rest of North America and all of South America. Many can’t understand why we refer to the US as “America,” and people from other countries often refer to our country as simply “the States.”
Writing the date beginning with the month.
People in the US typically write the date out in the format of month-day-year. People in other parts of the world, like the United Kingdom and Europe, write it out in the format of day-month-year. To us, that format is quite strange. But many people from other countries can’t understand why we write the month first, as to them it seems out of order.
Advertising prescription drugs all over the place.
In a Reddit thread asking the weirdest things Americans do, many users discuss how strange they think it is that the US advertises prescription drugs. Many said they found it to be one of the weirdest things about being in the US.
Reddit user NoDownvotesPlease said, “That was the weirdest one for me. ‘Ask your doctor for brand x antidepressants’ type commercials on TV. In the UK, your doctor tells you what drugs you should take, not the other way round.”
Hanging American flags everywhere.
In that same Reddit thread, users expressed how strange it was that that American flags are everywhere, from businesses to historical sites to homes.
The fact that our pharmacies sell so many things.
As BBC America pointed out, there are many differences between pharmacies in the US and drugstores in Europe and elsewhere. Many people from other places can’t believe that, in the US, our pharmacies sell drugs and junk food. They can’t believe that pharmacies basically double as convenience stores in the US.
Eating bread that almost always tastes sweet.
In the Reddit thread, many users discuss how they found it incredibly strange to constantly encounter sweet bread in the US.
Using the imperial system of measurement instead of the metric system.
The United States is one of only three countries who still use the imperial system of measurement, and everyone out there thinks we’re strange for doing so.
The constant commercials on TV.
When it comes to advertisements, the rest of the world can’t believe how many we have.
Reddit user WhatWouldTylerDo wrote, “I love America. But the one thing I hate is the placement of commercials on TV. It might be only for certain channels, but for a 30-minute show, there will be about four commercial breaks. And not even evenly spaced. Including one before the credits at the end of a show. Then it’ll jump straight from the credits to the next show.”
Expecting free refills everywhere we get a drink.
Many foreigners think it’s strange that free refills are offered and generally expected. It’s not the norm in many other places – France banned unlimited refills in 2017.
Using a lot of water in the toilet bowls.
Toilets are certainly different in the US than other parts of the world, and one amusing difference to note is how much more water there is in American toilets than other countries.
In the Reddit thread, one user wrote, “Seriously, why so much?!”
Putting giant gaps in between bathroom stalls.
Some people from other countries can’t believe how large the spaces are between bathroom stalls. It was brought up in many comments in the Reddit thread, with users saying they found the “massive” gaps to be an invasion of privacy and just plain strange.
Drinking huge coffees while we walk around.
In many other countries, like Europe, coffee is consumed in smaller quantities. That means they drink it quickly and they don’t take it to go.
But in the US, large to-go coffee cups are common. People from other countries find it very strange.
Taking leftover food home from a restaurant.
In the US, we don’t think twice about asking a server to box up our uneaten food so we can bring it home to finish another time. In other countries, this is incredibly strange and even considered to be rude. In France, for example, it’s so frowned upon that a law had to be passed to allow “doggy bags” to happen in order to get rid of food waste.
Eating giant portions.
Speaking of leftover food, people from other countries also can’t believe how big American portions are. That’s true when it comes to the size of dishes in restaurants, sodas and other drinks in fast-food chains, and even items that aren’t food.
Paying sales tax on pretty much everything we buy.
We might not like sales tax here in the US, but we expect it.
In other countries, the sales tax is often built into the price, so the price doesn’t change when you bring something to the register, and they find it strange that the US doesn’t do the same. It’s such a big difference that there are even advisories to people traveling to the US warning them of sales tax when shopping.
Tipping waiters and waitresses and other service professionals.
Not tipping in the United States is extremely frowned upon. In other parts of the world, a tip is not expected – it can even be considered rude. Tipping is another thing travelers are often warned about when coming to the States.
Chatting with strangers and making small talk.
One thing many Reddit users noted is that they found it strange that Americans chat with strangers so often. While some found it odd in a weird way, others found it nice.
Reddit user CompleteWoks said, “The hospitality, generosity and kindness to strangers, the friendliness and welcoming warmth is paralleled nowhere in the world.”
Using red cups to drink alcohol out of.
People around the world can’t believe how often Americans use red cups. In some countries, people throw “American parties,” where they all make sure to use red cups.
Wearing swimsuits to the beach.
In some other countries, like Europe, it’s considered totally normal to be topless on the beach. In fact, individuals who travel to the US often have to be warned to wear swimsuits in public, and keep them on.
Going into debt in order to go to college.
It’s no secret that going to college in the US can be extremely expensive and students can end up in debt to get a degree. A lot of other countries offer free college educations, and they can’t believe how much we spend on ours.
Throwing baby showers.
Baby showers are a fun custom in the US, but it’s not something many other parts of the world partake in. Outside of the US, some people find them strange, kind of rude, and aren’t interested in partaking in them.
Working constantly with very little vacation time.
According to research by the Center for American Progress, the United States is officially the most overworked country in the “developed” world. Some people in other countries can’t believe how much work we do, how long our hours are, how we eat lunch at our desks, and how we don’t take advantage of vacation time. Some other countries offer six weeks of paid vacation time as a standard. That’s certainly not the case here.

We launched Userbase 1 year ago promising the easiest way to create secure and private web apps — and it's gotten way easier!
Along with a number of optimizations and bug fixes to maximize Userbase’s performance and safeguard reliability.
We also added a free Starter tier with the following limits:
We listened, heard, and worked hard to make sure Userbase has everything you need to build powerful, secure, private apps. And there's plenty more to come!
Cossack Labs has completed a security audit of Userbase!
Userbase is a database-like product, purpose-built for web app user data. Unlike regular databases, user data is end-to-end encrypted using an encryption key that is never exposed to the Userbase server. Users own their own databases which are partitioned from databases of other users on the server-side, and can share their databases with other users, without exposing private keys to the server. Userbase is accessible through a very simple JavaScript SDK, directly from the browser.
We picked Cossack Labs because they specialize in cryptographic data security tools (both developer tools and bespoke solutions) for modern applications. Cossack Labs' experts that participated in this audit have decades of hands-on practical experience and formal backgrounds in information security and cryptography.
Cossack Labs found that Userbase prevents an adversary with privileged access to the Userbase server from accessing protected user data under the chosen set of assumptions and constraints. They also provided us with a list of findings and recommendations to strengthen Userbase. We have already implemented a number of their recommendations, and will continue implementing the rest as we work to improve Userbase.
Here is Cossack Labs’ public security audit report.
Here are our supporting documents:
Userbase can be contacted at<EMAIL_ADDRESS>or via Twitter @UserbaseHQ. If you believe you've found a security-related issue, please drop us an email at<EMAIL_ADDRESS>- bug bounty program may apply.

Installing Wordpress Multisite on a LEMP server for CentOS 6.
Set up WordPress Multisite in Nginx - CentOS 6
Difficulty: 2
Time: 20 minutes
You can manage multiple sites under one WordPress installation. This setup is a great convenience if you manage many sites completely independent of each other (or sites that are related, such as subdomains), as youíd otherwise have to log into different WordPress accounts.
For this article, we'll walk through setting up WordPress multisite for a primary domain and its subdomains.
We'll set up WordPress on a CentOS 6 system. The steps are for a non-root user with sudo
privileges.
We'll use these example sites:
| Site 1 |
coolexample.com (primary) |
| Site 2 |
coolexampleproduct.com
product.coolexample.com |
| Site 3 |
coolexamplecompany.com
aboutus.coolexample.com |
Prerequisites
You'll need a Linux, Nginx®, MySQL, and PHP (LEMP) stack configured. Make sure that Nginx, MySQL, and PHP are up and running. For instructions, see Build a LEMP stack (Linux, NGINX, MySQL, PHP) Ė CentOS 6.
As you install the software, make a note of your MySQL root account (administrator) password. You'll need it for these tasks.
You'll also need to set up the DNS for all your domains. Point them to the IP that will host your WordPress. Make sure to set up wildcard DNS if you're creating subdomains. To point your domain name to a cloud server, see Point your domain name to a server.
Create the Wordpress document root directory
Let's create the WordPress root directory for us to transfer the files into later.
- Create the document root directory. We'll use
/var/www/html
for this article.
sudo mkdir -p /var/www/html
Make a copy of your NGINX config file
We now need to update the default NGINX config file with our WordPress settings. Letís work from our nginx.conf
file to configure it for WordPress.
- Double-check that you have the file first (you should).
sudo vim /etc/nginx/conf.d/default.conf
- Create a backup copy just in case.
sudo cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.bak
Populate your NGINX config file with your WordPress information
Now that we have a backup, letís start editing the config file.
- Open the
.conf
file.
sudo vim /etc/nginx/conf.d/default.conf
- Inside the file, make these changes.
Some of these changes may have already been made when you installed your LEMP stack.
After your changes, your file may look something like this:
# The default server
#
server {
listen 80 default_server;
server_name coolexample.com product.coolexample.com aboutus.coolexample.com;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
root /var/www/wordpress;
index index.php index.html index.htm;
}
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
...
# pass the PHP scripts to FastCGI server listening on <IP_ADDRESS>:9000
#
location ~ \.php$ {
root /var/www/wordpress;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
$document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
- Save and close.
- Restart NGINX to make your changes take.
sudo service nginx restart
Create a MySQL database and administrator for WordPress
Set up your MySQL database with an administrator so that WordPress has a place to store all your site and user information.
All MySQL code statements must end with a semi-colon (;).
- Log into your MySQL admin account.
mysql -u root -p
- At the prompt, enter your MySQL root password.
- At the MySQL prompt, create your WordPress database. For this article, we'll use the database name "wordpress."
CREATE DATABASE wordpress;
- Create the database administrator account, and set the user's credentials. We'll use "wordpressadmin" as the example user name, and "wordpresspassword" as the password.
CREATE USER wordpressadmin@localhost IDENTIFIED BY 'wordpresspassword';
As a best security practice, create a strong password. Keep your user name and password handy, as you'll need them later.
- Give, or grant, your admin permissions to the database.
 TO wordpressadmin@localhost;
GRANT
is one of the account management statements that the MySQL server notices and loads into memory right away. Therefore, a manual reload/restart should not be necessary. However, if you like, you can check the permissions using SHOW GRANTS:
SHOW GRANTS FOR 'wordpressadmin'@'localhost';
- If the privileges don't take, flush the privileges to activate the user.
FLUSH
forces a reload of the cache.
FLUSH PRIVILEGES;
- Exit MySQL to return to your normal command prompt.
exit
You're finished!
Download WordPress
Your system is now ready to install WordPress into your directory. WordPress is available in a tar.gz
or zip
format. We'll get the tar.gz
file.
- Download the WordPress files from the official site using
wget
:
cd ~
wget http://wordpress.org/latest.tar.gz
This URL always links to a compressed file of the latest stable version of WordPress.
- Extract, or untar, the application directory.
tar -xf latest.tar.gz
This command creates a directory called "wordpress" in your home directory.
- Move the files into the WordPress document root.
sudo mv wordpress/* /var/www/html/
- Change ownership to the user
www-data
so that you'll be able to work with WordPress uploads, plugins, and themes.
sudo chown nginx:nginx * -R
- Let's add a designated WordPress user. For this tutorial, we'll call ours
wordpress_user
.
sudo adduser wordpress_user
- Give your user permissions to modify the content.
sudo usermod -a -G nginx wordpress_user
Install WordPress
Now you can access the WordPress web interface.
- In your web browser, enter your primary domain name. In our example, that's
http://coolexample.com.
(If the Nginx default page displays, append
/wp-admin/
to your URL.)
You may get an introductory page. If so, click Let's go! to continue.
- On the next page, fill out your WordPress MySQL database credentials. You can leave the Database Host as is (localhost), since that's what we defined, and Table Prefix as wp_.
- Click Submit.
The following page displays the error message "Sorry, but I can't write the wp-config.php file." Not to worry! Let's create our wp-config
file now.
Create and modify the WordPress configuration file
- Back in your terminal, navigate to your WordPress document root.
cd /var/www/html
- List files using
ls
to make sure that wp-config-sample.php
is among them.
- Copy the sample configuration file.
sudo cp wp-config-sample.php wp-config.php
- Open your configuration file for editing.
sudo vim wp-config.php
- In the file, look for the following section of code (starting with "MySQL settings"), and enter your corresponding values of the three
DB_
variables that we filled out earlier in the WordPress web interface (database name, database username, mysql root password) with the credentials you created earlier.
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');
/** MySQL database username */
define('DB_USER', 'wordpressadmin');
/** MySQL database password */
define('DB_PASSWORD', 'password');
- Farther down in the file, find the line
/* That's all, stop editing! Happy blogging. */
and add these lines:
/* Multisite settings */
define( 'WP_ALLOW_MULTISITE', true );
- Save and close the file.
- Restart Nginx.
sudo service nginx restart
Continue setup in WordPress web interface
- Return to your browser and click Run the Install on the screen you were just on to continue the WordPress web installation. You should be taken to the WordPress 5-minute install screen.
- Choose a user name and password. Use the password supplied if you like; just be sure to save it somewhere handy.
- Click Install WordPress.
If at any point during web installation you get an error such as a 404 or 504 page, reload the wp-admin page (http://coolexample.com/wp-admin/
).
Enable multisite
- In your browser, continue the WordPress web installation. Click on Tools on the left-hand panel, then Network Setup.
- Because we're working with sub-domains, choose sub-domainsand change your Network Title if you like. Click Install.
- In the next Network Setup screen, copy the
wp-config
code in the first section. We'll paste this into our configuration file.
For Nginx, there's no htaccess
file. We'll ignore the .htaccess
code.
The code resembles this:
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', coolexample.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
- In your terminal, pull up your
wp-config
file.
cd /var/www/html
sudo vim wp-config.php
- Find the section torwards the end of the file we were modifying, and paste the code you copied right before
/* That's all, stop editing! Happy blogging. */
.
- Save and close the file.
Create additional sites or subdomains
- Back in your browser, click Log In at the bottom of the page or simply reload the page. (Log back in if your password isn't saved.)
- To the left of that on the top navigation bar is My Sites. Hover/mouse over it, and from the drop-down menu, select Network Admin, then Sites.
At the top, there should now be a "Network Admin: (your domain name)
option in the menu bar, if it wasn't there earlier.
- On the main screen, next to Sites, click Add New.
- Fill out your first subdomain information.
- Click Add Site to finish.
- Repeat for all your subdomains.
Next Steps
Congratulations! You have successfully set up a WordPress multisite. You'll be able to manage all your sites from your WordPress panel.
There's much you can do from here. One option is to map your sub-domains to external domains. See Set up WordPress Domain Mapping - CentOS 6 for instructions.

The last 27,28 and 29 of September was the ekoparty security confence,in this conference I did a workshop focused on mobile application implementations. And I talked about some security examples and implementations where thoose examples were based on differents mobile penetration test what I did.
Where I showed some "bad implementations" inside the code, hardcoded issues like usernames, passwords, services (FTP, SFTP, etc) or the lack of binary protections like obfuscation, anti-emulation, root checker, bad implementations of certificate pinning, SSL/TLS, etc.

When I try to install Synergy 3.5a I get an error right when it seems to have finished the installation, telling me that it couldn't install it and that I should try to manually start "Synergy.app".
When I then try to open the control panel via the System Preferences, it tells me that I can't change my Synergy preferences because it's "not possible on a PowerPC-Mac" (directly translated from a german OS).

Looks like the Universal Binary somehow got stripped to be uni-architecture. I'll try to find out why. Thanks for reporting the issue.

Have posted an updated release (3.5a2) that corrects this problem.

Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.
Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.
Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.
Home Automation
This is an open source system for integrating wireless Arduino sensors to an awesome home automation platform called OpenHAB. It allows you to get email notifications and audio alarming based on sensor data. The OpenHAB platform provides the mobile app server, browser based interface, actions (emails, Android/Apple push notification services), and rules engine needed to do real home automation.
how much functionality and flexibility can be packed into a single Arduino sensor, here is the parameters
1) smoke & combustible gas
2) motion
3) fire
4) sound (dog bark)
5) light level
6) temperature & humidity
Plant Monitoring System
you are going on a vacation for a week or so and are worried about your house plant at home.Here is a great project to under take a week before you head out for your vacation. Build yourself a plant monitoring and notification system with the following feature Monitor the Temperature,Light Value and Soil moisture value using dweet.io OR using the new Amazon IoT service to log data to AWS - DynamoDB. Use AWS -SNS notification, to send out an email to yourself, so that you can inform your cousin/neighbor to quickly water the plant or check on your thermostat at home.
Track and Control Your Car Remotely
Actually, many of us may suffer or afraid from being his car stolen. In this project, we will try to help you to protect your cars and even control them remotely.
Basically, you have to leave a mobile phone in your car and when the car starts to move it uses its sensors to detect that and will send to you a message on your mobile phone where ever you are. Then, you can send a message to stop the car immediately so the thief couldn't turn it on again as well you can send another message to know its location using GPS to get it from there.
All of these can be implemented so easily and requires no experience in coding. All you need is Arduino, any Android smart phone and 1Sheeld that connects the mobile and Arduino via Bluetooth and make use of its mobile app, so no need for Android coding.
