XKBPRINT(1) XKBPRINT(1) NAME xkbprint - print an XKB keyboard description SYNOPSIS xkbprint [options] source [ output_file ] DESCRIPTION The xkbprint command generates a printable or encapsulated PostScript description of the XKB keyboard description specified by source. The source can be any compiled keymap (.xkm) file that includes a geometry description or an X display specification. If an output_file is speci‐ fied, xkbprint writes to it. If no output file is specified, xkbprint creates replaces the extension of the source file with .ps or .eps depending on the requested format. If the source is a non-local X dis‐ play (e.g.:0), xkbprint appends the appropriate prefix to the display specification, replacing the colon with a dash. For a local display, xkprint uses server-n where n is the number of the display. OPTIONS -?, -help Prints a usage message. -color Print using the colors specified in the geometry file; by default, xkbprint prints a black-and-white image of the keyboard. -dflts Attempt to compute default names for any missing components, such as keys. -diffs Show symbols only where they are explicitly bound. -eps Generate an encapsulated PostScript file. -fit Fit the keyboard image on the page (default). -full Print the keyboard at full size. -grid res Print a grid with resmm resolution over the keyboard. -if fontName Specifies an internal PostScript type 1 font to dump to the spec‐ ified output file or to fontName.pfa, if no output file is speci‐ fied. No keyboard description is printed if an internal font is dumped. -label type Specifies the labels to be printed on keys; legal types are: none, name,code,symbols. -lc <locale> Specifies a locale in which KeySyms should be resolved. -level1 Generate level 1 PostScript. -level2 Generate level 2 PostScript. -lg group Print symbols in keyboard groups starting from group. -ll level Print symbols starting from shift level level. -mono Generate black-and-white image of keyboard (default). -n num Print num copies. -nkg num Print the symbols in num keyboard groups. -npk num Number of keyboard images to print on each page; for EPS files, this specifies the total number of keyboard images to print. -o file Write output to file. -Rdirectory Use directory as the root directory; all path names are inter‐ preted relative to directory. -pict which Controls use of pictographs instead of keysym names where avail‐ able. which can be any of all, none, or common(default). -synch Forces synchronization for X requests. -w level Sets warning level (0 for no warning, 10 for all warnings).

Eden Hazard: 'I missed out playing under Frank Lampard at Chelsea'
Eden Hazard has revealed that he would have liked to have played under Chelsea boss Frank Lampard.
by Darren PlantDuring the summer transfer window, Hazard ended his long-term association with the Blues to sign for Real Madrid.
However, despite his departure from Stamford Bridge, the Belgium international has acknowledged that he has been left hugely impressed by his former club's progression since the arrival of the ex-midfielder.
Speaking to Sky Sports News, Hazard said: "When I watch them, [there is] no Hazard but it is a party.
"They can score a lot of goals, the fans are happy, they are third in the league, it is going to be a great season. They just need to stay there and win games.
"We all know Willian, Jorginho they are very good. Also with the young players coming through, it is great to see the club high and I hope they can stay there."
When quizzed if he feels like he has missed out on working with Lampard, he added: "Yeah, of course."
Hazard netted 110 goals from his 352 appearances for Chelsea in all competitions.

[gecode-users] Gecode terminates on incomplete solution
Christian Schulte
cschulte at kth.se
Thu Jun 12 21:30:00 CEST 2014
The linear constraints for Boolean are in fact specialized versions that are
as smart as possible, they are linear only by name ;-)
But there is one thing that will never go away: Gecode has not been built to
be good at Booleans! You might be much better off with a SAT solver or a
Pseudo Boolean solver... If you have a mix of integers and Booleans then
Gecode is fine.
Cheers

Subject: Re: [gecode-users] Gecode terminates on incomplete solution
Hi Christian,
thanks for your reply!
You are right, the boolean variants of these constraints can be modeled like
that. In fact, my current solution works fine with "linear" - but it's slow.
Therefore, I was looking for specialized constraints like "distinct" or
"atmost", because Max indicated that they might be faster ("They usually
perform much better than linear constraints.").
If however the "linear" constraint in Gecode is already as good as possible
(I use the first one here
http://www.gecode.org/doc-latest/reference/group__TaskModelIntLB.html#ga7dba
f2c0ceb605f34731328004c73b57),
I'll stick with that. Since I don't know that much about constraint
propagation, I imagine (!) that a linear constraint requires some sort of
computation to sum up a (weighted) array, while an implementation of
"atmost_1" would only need to store the single variable from the array that
is currently true, and then prevent the rest from being set to true. That's
why I currently believe (!) that "linear" might by unnecessarily powerful
and not optimally efficient for my use case.
Again, I may well be wrong.
A "distinct" constraint on boolean variables would only make sense for two
variables, obviously. What I need is something like "distinct except 0"
(http://www.emn.fr/z-info/sdemasse/gccat/Calldifferent_except_0.html),
i.e. variables set to zero/false are ignored and only one variable is
allowed to be true/one. I can't achieve that with inequality, because two
variables may be 0, actually even all variables may be 0.
It does work with a pair-wise NAND constraint implemented like that:
forall i != j do: rel(*this, variables[i], BOT_AND, variables[j], 0); But
that gives me O(n^2) constraints only to express the single requirement that
at most one of these variables can be true. And I have
O(m^2) of these if m is my problem size, so I would end up with O(m^4)
constraints in Gecode. Am I overlooking something like an inequality
constraint for multiple boolean variables?
Best
Philipp

PH 142 is an introduction to statistics and data science, primarily for MPH and undergraduate public health majors, and others interested in public health majors. The course material focuses on the biomedical applications of basic data summarization using the statistical programming language: R, classical problems in probability/statistical distributions (Normal, binomial, Poisson), and statistical inference techniques. For Chemistry and Chemical Biology majors, this course can be taken as an allied subject. Priority is given to public health majors but the class is generally accommodating of students in other majors.
High School Algebra
Course is offered in the Spring, Summer, and Fall
3 hours of lecture per week (typically webcasted). 1 hour of discussion/1 hour of laboratory per week (not mandatory). 3-5 hours of homework per week.
This class fulfills 4 units of an Allied subject (for Chemistry/Chemical Biology majors) and requires no previous knowledge of statistics.
The information above is specifically based on the course in Fall 2018 taught by Professor Corrinne Riddell and Professor Alan Hubbard. While the basic statistical skills learned are consistent, the material has been known to vary with different professors
Good for people who have no coding experience and would like to learn the basic
Not necessarily relevant to any College of Chemistry courses but skills gained can be utilized for data analysis and presentation in research

My name is Sylvia Kinyanjui originally from Ngong.I'm currently learning Software development at Moringa School.I am 26 years old.I enjoy Painting and designing.
I turned to coding because It has always been a dream of mine to be able to design my own games and that needs some knowledge on coding and programming
I have done a couple of practice projects since I started prep and I hope to join core and advance my skill.Below are links to my Business pages and Social Networks,and one of my projects on github:

This is a recreation of the famous gapminder visualization adapted for our Yelp data analysis. This visualization shows the trend of checkins in the businesses tagged under "Food" in the 10 cities over a period of 24 hours of the day. The control bar at the bottom allows us to visualize the trends in checkin for these 10 cities. The radius of these bubbles that represent these cities are proportional to the total number of reviews recorded on Yelp in these cities.
As a matter of fact it's clearly visible that Las Vegas buzzes with social activity and leads not only in the number of checkins but also is way above others with repoect to the total number of review texts. On the other hand Kalsruhe has very minimal number of businesses recorded Yelp as per the dataset and hence very little social activity.

If you just finished a philosophy course this fall, you might be wondering what to read next.
Here’s some recommendations: These are good, accessible yet challenging classics.
For more in depth recommendations, go to my philosophy site here.
Finally, if you are overwhelmed with all the good books to read in the world,do the intentional reading project. It is a proven plan to help you read more good books this year.


Before Change
dtypes = [ar.dtype for ar in arrays]
dtype = _np.find_common_type(dtypes, ())
try:
index = dtypes.index(dtype)
except ValueError:
index = 0
if arrays[index].flags["FORTRAN"]:
// prefer Fortran for leading array with column major order
After Change
// use the most generic type in arrays
chars = [arr.dtype.char for arr in arrays]
scores = [_type_score.get(x, 5) for x in chars]
max_score = max(scores)
ind_max_score = scores.index(max_score)
// safe upcasting for mix of float64 and complex64 --> prefix "z"
if max_score == 3 and (2 in scores):
max_score = 4
if arrays[ind_max_score].flags["FORTRAN"]:
// prefer Fortran for leading array with column major order
prefer_fortran = True
// Get the LAPACK prefix and the corresponding dtype if not fall back

"Superlinker" allows your links to be aviable in your parent element, so your visitors will be able to get to your links without searching the small letters :D
You just have to load the script "superlinker.js" in your HTML document, it contains the "superlinker" class
First, add the "superlink-blank" or "superlink" classes to your "a" tag in your HTML, just like this:
Now, let's see what's next!
Once you have prepared your workspace, you just have to add the next javascript code:
The default configuration of superlink applies color "rgba(255,255,255,0.3)" on mouseenter event and makes the font 1.4 times bigger. It also makes your cursor to be a pointer ;)
Now you can click on any place of the parent box of the link! It's comfortable and beautiful :)
You can change the background color and fontsize on the hover events!, see the example:
Upps! We need to change the classes for the superlink because they are different from the ones we have up there, just add the "blankClass" and "selfClass" parameters when you initialize the Superlinker class
"Superlinker" adds a class to the parent element, so you can desactivate the hover effects and modify them in your CSS file :)
Follow the example:
The "hovered" class is the default class name for the parent element, but you can replace it for whatever you want. If you want to delete ALL hover effects you just have to add "{hover:false}" and it won't be there anymore (including the cursor pointer change), but you can click the parent element and you will still get to your URL :)

TEMPNAM
Section: Linux Programmer's Manual (3)
Updated: 2014-02-27
Index
Return to Main Contents
NAME
tempnam - create a name for a temporary file
SYNOPSIS
#include <stdio.h>
char *tempnam(const char *dir, const char *pfx);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
tempnam():
_BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
Never use this function.
Use
mkstemp(3)
or
tmpfile(3)
instead.
The
tempnam()
function returns a pointer to a string that is a valid filename,
and such that a file with this name did not exist when
tempnam()
checked.
The filename suffix of the pathname generated will start with
pfx
in case
pfx
is a non-NULL string of at most five bytes.
The directory prefix part of the pathname generated is required to
be "appropriate" (often that at least implies writable).
Attempts to find an appropriate directory go through the following
steps:
- a)
-
In case the environment variable
TMPDIR
exists and
contains the name of an appropriate directory, that is used.
- b)
-
Otherwise, if the
dir
argument is non-NULL and appropriate, it is used.
- c)
-
Otherwise,
P_tmpdir
(as defined in
<stdio.h>)
is used when appropriate.
- d)
-
Finally an implementation-defined directory may be used.
The string returned by
tempnam()
is allocated using
malloc(3)
and hence should be freed by
free(3).
RETURN VALUE
On success, the
tempnam()
function returns a pointer to a unique temporary filename.
It returns NULL if a unique name cannot be generated, with
errno
set to indicate the cause of the error.
ERRORS
- ENOMEM
-
Allocation of storage failed.
CONFORMING TO
SVr4, 4.3BSD, POSIX.1-2001.
POSIX.1-2008 marks
tempnam()
as obsolete.
NOTES
Although
tempnam()
generates names that are difficult to guess,
it is nevertheless possible that between the time that
tempnam()
returns a pathname, and the time that the program opens it,
another program might create that pathname using
open(2),
or create it as a symbolic link.
This can lead to security holes.
To avoid such possibilities, use the
open(2)
O_EXCL
flag to open the pathname.
Or better yet, use
mkstemp(3)
or
tmpfile(3).
SUSv2 does not mention the use of
TMPDIR;
glibc will use it only
when the program is not set-user-ID.
On SVr4, the directory used under d) is
/tmp
(and this is what glibc does).
Because it dynamically allocates memory used to return the pathname,
tempnam()
is reentrant, and thus thread safe, unlike
tmpnam(3).
The
tempnam()
function generates a different string each time it is called,
up to
TMP_MAX
(defined in
<stdio.h>)
times.
If it is called more than
TMP_MAX
times,
the behavior is implementation defined.
tempnam()
uses at most the first five bytes from
pfx.
The glibc implementation of
tempnam()
will fail with the error
EEXIST
upon failure to find a unique name.
BUGS
The precise meaning of "appropriate" is undefined;
it is unspecified how accessibility of a directory is determined.

| PostgreSQL 9.6.2 Documentation | |||
|---|---|---|---|
| Prev | Up | Chapter 15. Parallel Query | Next |
Because each worker executes the parallel portion of the plan to completion, it is not possible to simply take an ordinary query plan and run it using multiple workers. Each worker would produce a full copy of the output result set, so the query would not run any faster than normal but would produce incorrect results. Instead, the parallel portion of the plan must be what is known internally to the query optimizer as a partial plan; that is, it must be done so that each process which executes the plan will generate only a subset of the output rows in such a way that each required output row is guaranteed to be generated by exactly one of the cooperating processes.
Currently, the only type of scan which has been modified to work with parallel query is a sequential scan. Therefore, the driving table in a parallel plan will always be scanned using a Parallel Seq Scan. The relation's blocks will be divided among the cooperating processes. Blocks are handed out one at a time, so that access to the relation remains sequential. Each process will visit every tuple on the page assigned to it before requesting a new page.
The driving table may be joined to one or more other tables using nested loops or hash joins. The outer side of the join may be any kind of non-parallel plan that is otherwise supported by the planner provided that it is safe to run within a parallel worker. For example, it may be an index scan which looks up a value based on a column taken from the inner table. Each worker will execute the outer side of the plan in full, which is why merge joins are not supported here. The outer side of a merge join will often involve sorting the entire inner table; even if it involves an index, it is unlikely to be productive to have multiple processes each conduct a full index scan of the inner table.
It is not possible to perform the aggregation portion of a query entirely in parallel. For example, if a query involves selecting COUNT(*), each worker could compute a total, but those totals would need to combined in order to produce a final answer. If the query involved a GROUP BY clause, a separate total would need to be computed for each group. Even though aggregation can't be done entirely in parallel, queries involving aggregation are often excellent candidates for parallel query, because they typically read many rows but return only a few rows to the client. Queries that return many rows to the client are often limited by the speed at which the client can read the data, in which case parallel query cannot help very much.
PostgreSQL supports parallel aggregation by aggregating twice. First, each process participating in the parallel portion of the query performs an aggregation step, producing a partial result for each group of which that process is aware. This is reflected in the plan as a PartialAggregate node. Second, the partial results are transferred to the leader via the Gather node. Finally, the leader re-aggregates the results across all workers in order to produce the final result. This is reflected in the plan as a FinalizeAggregate node.
Parallel aggregation is not supported in all situations. Each aggregate must be safe for parallelism and must have a combine function. If the aggregate has a transition state of type internal, it must have serialization and deserialization functions. See CREATE AGGREGATE for more details. Parallel aggregation is not supported for ordered set aggregates or when the query involves GROUPING SETS. It can only be used when all joins involved in the query are also part of the parallel portion of the plan.
If a query that is expected to do so does not produce a parallel plan, you can try reducing parallel_setup_cost or parallel_tuple_cost. Of course, this plan may turn out to be slower than the serial plan which the planner preferred, but this will not always be the case. If you don't get a parallel plan even with very small values of these settings (e.g. after setting them both to zero), there may be some reason why the query planner is unable to generate a parallel plan for your query. See Section 15.2 and Section 15.4 for information on why this may be the case.
When executing a parallel plan, you can use EXPLAIN (ANALYZE, VERBOSE) to display per-worker statistics for each plan node. This may be useful in determining whether the work is being evenly distributed between all plan nodes and more generally in understanding the performance characteristics of the plan.

There are corner cases where Haskell doesn’t shine that well, but smart people found ways around them.
I would like to expand your horizons when it comes to Haskell, as a language, and also introduce you to few GHC language extensions.
This is a shallow talk, it doesn’t go in to details or too deep in to the problems, its here just to inspire you to do that your self.
value :: type
type :: kind
Values have types:
True :: Bool
map :: (a -> b) -> [a] -> [b]
Types have kinds:
Int :: *
Maybe :: * -> *
(->) :: * -> * -> *
And all the way up, until you reach co-turtles.

Since the introduction of the private branch exchange (PBX) in the 1970s, companies have become dependent on the many features that were introduced over time. Today, businesses have a variety of options when it comes to telephone systems. Many are choosing the cloud with a hosted PBX solution in order to reduce capital expenses, maintenance & upgrade costs – while still reaping the benefits of the latest PBX features.
This article aims to provide a guide through the (initial) planning and deployment of a FreePBX & Asterisk VoIP server and assumes you will be starting from a base install of CentOS 6.4

A PBX is a system that connects internal telephone extensions to outside public & mobile telephone networks. An IP (Internet Protocol) PBX is a PBX that provides audio, video, and instant messaging communication through data networks connected with the Public Switched Telephone Network (PSTN) for worldwide telephony communication.
In addition to the traditional PSTN (i.e. landline), modern PBX systems also utilize the Voice over Internet Protocol (VoIP). VoIP gateways enable businesses to use their managed intranets to help reduce long-distance expenses; and enjoy the benefits of a single network for voice and data communication.
Asterisk is an open source software implementation of a telephone PBX. Like any PBX, it allows connected telephones to make calls to one another, and to connect to other telephone services, such as traditional landlines (i.e. PSTN) and VoIP networks.
The Asterisk software includes many features available in proprietary PBX systems:
In addition, users can create new functionality by writing dial-plan scripts in several of Asterisk’s own extensions languages or by adding custom, loadable modules.
FreePBX is an open source graphical user interface (GUI) that controls and manages Asterisk. Without FreePBX, Asterisk’s configuration files could only be modified via the command line. FreePBX can be installed manually or as part of a pre-configured Distro.
The FreePBX Distro is an open source Unified Communications (UC) Server that includes the Asterisk VoIP server, the FreePBX GUI, and assorted dependencies, which include (but are not limited to):
The FreePBX Distro is based on CentOS, which has binary compatibility with Red Hat Enterprise Linux. FreePBX is a very large part of why Asterisk has been as successful as it has.
First, you must make a few structural decisions, before you deploy your cloud PBX.
Voice quality on VoIP calls is affected by network latency, among other factors. Thus, it is advisable to select a datacenter that is closest to the general, geographic location of the majority of your anticipated calls.
To access your IP PBX server after deployment, you will need to open a web browser and navigate to your cloud server’s IP address or fully qualified domain name (FQDN). If you wish to assign a FQDN to your VoIP server, make sure that you assign a FQDN as your server’s hostname – when you create your DigitalOcean cloud server in the next step – via the DigitalOcean Control Panel.
Deciding on the best size machine for your cloud IP-PBX server is not an exact science. Try to best anticipate your average call volume; and then follow the steps outlined in: How To Create Your First DigitalOcean Droplet Virtual Server to deploy a CentOS 6.4
virtual private server (VPS).
Generally speaking, a VPS with:SSH Keys
For increased security, it is advisable that you:
- Create your droplet with pre-installed SSH keys. See How To Use SSH Keys with DigitalOcean Droplets (Windows users: Refer to the article cited, next); and
- Disable password logins. See How To Create SSH Keys with PuTTY to Connect to a VPS.
| Memory | Concurrent Calls |
|---|---|
| 512 MB | Supports approx. 5-15 |
| 1 GB | Supports approx. 15-25 |
| 2 GB | Supports approx. 25-50 |
| 4 GB | Supports approx. 50-100 |
| 8 GB | Supports approx. 100-175 |
| 16 GB | Supports approx. 175+ |
NOTE: It is safe to “guess low.” If you underestimate your call volume, try adding swap space. See How To Add Swap on CentOS 6 | DigitalOcean. In addition, DigitalOcean makes it easy to resize your cloud server, later.
/etc/hosts
Next, follow the steps outlined in Setting the Hostname & Fully Qualified Domain Name (FQDN) on Ubuntu 12.04 or CentOS 6.4. If entered properly at the time that your cloud server was created, the machine’s hostname
should already be formatted as a FQDN. If so, feel free to skip to the section titled Setting the Fully Qualified Domain Name (FQDN).
You can set your server’s timezone to whatever you want. It may be best to set it to the same timezone as most of your callers. If you are unsure which timezone would be best, consider using universal coordinated time (UTC) – also known as Greenwich Mean Time
.
To view the current timezone, execute:
date
To change your CentOS server’s timezone, you need to create a symbolic link from a zone file in /usr/share/zoneinfo/
to /etc/localtime
. To do so, you first need to find the zone file for your timezone (see the examples below for common possibilities):
ln -sf /usr/share/zoneinfo/EST /etc/localtime
ln -sf /usr/share/zoneinfo/US/Central /etc/localtime
ln -sf /usr/share/zoneinfo/US/Pacific /etc/localtime
ln -sf /usr/share/zoneinfo/UTC /etc/localtime
Now you need to install the available software updates for your CentOS server. Doing so patches security holes in packages and helps protect your droplet against unauthorized access.
yum update
First, navigate to your server’s /tmp
directory by executing the following command:
cd /tmp
Next, download the FreePBX Distro installation script by executing:
wget http://upgrades.freepbxdistro.org/blank-centos-installer/4.211.64-track/4.211.64-1-Installer-Script.sh
This script assumes you have a base install of CentOS 6.4. It will convert your system to a FreePBX Distro.
Then, make the script executable:
chmod +x 4.211.64-1-Installer-Script.sh
Run the installer script, by executing:
./4.211.64-1-Installer-Script.sh
Once completed, you should have a full-functioning IP-PBX server, based on the FreePBX Distro. (If you encountered any problems, feel free to create a post in the FreePBX Distro Discussion & Help forum.)
FreePBX publishes update scripts for new FreePBX Distro releases on its website. It is advisable that you bookmark that page and refer to it on a regular basis to obtain any recent upgrade scripts that may have been made available.
To update your FreePBX Distro to the most recent release, you will need to execute a series of individual shell scripts AND do so in sequential order.
The FreePBX Version Numbering System tells you at a glance which versions of core components a particular FreePBX Distro release is comprised of.
For example, FreePBX Distro 4.211.64-1 means:
In a terminal, execute:
cat /etc/schmooze/pbx-version
As mentioned above, the FreePBX Distro release identifier is the final number. For example, in this article’s previous steps, you deployed the following script: 4.211.64-1-Installer-Script.sh
. Notice the final numerical digit: The number 1
in this example.
The first time you, ever, execute an update script, enter the following commands in a terminal window (to create a directory in which to store all future Distro-update scripts):
cd
mkdir -p ~/FreePBX/UpdateScripts
cd ~/FreePBX/UpdateScripts
Upgrade Step 1: Execute, in a terminal window:
wget http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-2.sh
Upgrade Step 2: Make the file executable:
chmod +x upgrade-4.211.64-2.sh
Upgrade Step 3: Execute:
./upgrade-4.211.64-2.sh
The Distro upgrade script will update both FreePBX components (Asterisk & the FreePBX web GUI) and all base CentOS components.
Upgrade Step 4: Specific Script Instructions
Note or carry out any special instructions displayed (if any) at the end of the upgrade, such as to reboot the system.
Upgrade Step 5: Confirm the New FreePBX Distro Version
Check the updated (now current) version file – again, by executing cat /etc/schmooze/pbx-version
– to confirm the current installed version of the FreePBX Distro is the expected newer version.
Upgrade Step 6: Repeat Upgrade Steps 1-5
for each individual update script, in sequential order, found below.
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-3.sh
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-4.sh
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-5.sh
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-6.sh
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-7.sh
http://upgrades.freepbxdistro.org/stable/4.211.64/upgrade-4.211.64-8.sh
Make sure to save each upgrade-script in ~/FreePBX/UpdateScripts
.
To confirm that FreePBX & Asterisk were installed successfully, open a web browser and navigate – via https://
– to your cloud server’s FQDN or IP address, and you should be greeted by the FreePBX administrator-account setup screen.
That username and password will be used in the future to access the FreePBX configuration screen, via the web GUI.
Note: This password does not change the underlying operating system’s root password, if any. It is only used for access to the FreePBX web interface.
To configure Postfix & Cyrus SASL, begin with Step Two of this article: How To Install Postfix on CentOS 6 | DigitalOcean; but skip the section related to editing the /etc/imapd.conf
file.
Any server accessible from the public Internet should be security hardened, and an Asterisk IP-PBX is no exception. Security best practices, however, are not within the scope of this article.

The Basics
Are you thinking about trying rock climbing? Climbing is a fun and challenging sport that has a surge of popularity in recent years. Almost anyone can climb: you don't need a high level of strength or fitness to get started. Gear is available for men, women, and children of all shapes and sizes, and most gyms will allow children as young as three to climb. Climbing is not about brute force. Climbing more difficult routes does take some strength, mostly in your legs and hands, but it also takes skill and problem-solving ability.
Oh, and it is okay if you are afraid of heights. Really. Just keep your eyes on the wall.

Max's database ( i.e.
t_database ) support currently consists of a SQLite ( http://sqlite.org ) extension which is loaded dynamically by Max at launch time. Because it is loaded dynamically, all interfacing with the sqlite object relies on Max's message passing interface, using object_method() and related functions.
For most common database needs, a C-interface is defined in the ext_database.h header file and implemented in the ext_database.c source file. The functions defined in this interface wrap the message passing calls and provide a convenient means by which you can work with databases. ext_database.c is located in the 'common' folder inside of the 'max-includes' folder. If you use any of the functions defined ext_database.h, you will need to add ext_database.c to your project.
| typedef t_object t_database |
A database object.
Use db_open() and db_close() to create and free database objects.
| typedef t_object t_db_result |
A database result object.
This is what the database object returns when a query is executed.
A database view object.
A database view wraps a query and a result for a given database, and is always updated and in-sync with the database.

| t_max_err db_transaction_start | ( | t_database * | db | ) |
Begin a database transaction.
When you are working with a file-based database, then the database will not be flushed to disk until db_transacation_end() is called. This means that you can _much_ more efficiently execute a sequence of queries in one transaction rather than independently.
That database object reference counts transactions, so it is possible nest calls to db_transacation_start() and db_transacation_end(). It is important to balance all calls with db_transacation_end() or the database contents will never be flushed to disk.

| t_max_err db_view_create | ( | t_database * | db, |
| const char * | sql, | ||
| t_db_view ** | dbview | ||
| ) |
A database view is a way of looking at a particular set of records in the database.

| va_list | ap | ||
| ) |
Execute a SQL query on the database.
| db | The t_database pointer for your database instance. |
| dbresult | The address of a t_db_result pointer. If the pointer is passed-in set to NULL then a new dbresult will be created.

As a beginner I did not worry too much about getting the best equipment. I was more worried about the price since I was on a budget. Luckily i was bale to find a great deal during black friday. I started off with purchasing a Nikon D3300 bundel. The bundel came with the Nikon D3300 body, a 18-55mm wide lense, a 50-200mm telephoto lense, and a Wi-Fi adaptar. I spent about $600 total and was pretty happy with what I bought.
After 2 years of learning how to ues the features on my camera I decided it was time to upgrade to new lenses. I spent about 3 months looking at deals and was able to find one that caught my eye. The bundle came with a macro lense and a fixed portrait lense. I spent about $500 in total.

I’ve wanted to be a teacher ever since I was 15 years old. I remember the English teacher who helped me love having Socratic discussions. I remember the band teacher who challenged me as a young adult. I remember teachers coming to swim meets, concerts, plays, and even graduation parties when we were done with school.
As a teacher, I’ve continued to grow my love of teaching by working with my colleagues to grow in our practice. My first principal showed me that it was okay to ask questions as well as proudly share what we’re doing in our classes. Doing so taught me how to grow in my own learning. He also gave me the okay to go to my first professional conference, where I learned about Flipped Learning, where I first heard about TechSmith.
Through all of this, I’ve developed a new love of teaching teachers. I shared at my first conference after nearly a year of flipping, and I caught the bug. I continue to look forward to sharing successes, failures, insights, and questions, at conferences. I also look forward to being challenged and being forced to explain why I do what I do in the classroom. It’s where growth happens. It’s also where I feel like my career is taking me.
I went to Colorado in the summer of 2011 and shared my learning. It’s also where I got to meet Dave McCollom and Troy Stein for the first time. Ever since then, I have had a fantastic working relationship with TechSmith.
I’m very excited to (officially) announce that I’m going to be shifting into a new role at the beginning of March. TechSmith has asked me to join their Academic Team as the Academic Customer Solutions Engineer. So, what does that mean?
It means I’m going to be a resource for teachers regionally and across the nation. My purpose is to help teachers use technology in their classrooms more effectively. I’ll be the bridge between classroom practice and TechSmith as they look to help teachers solve problems through the better use of technology.
While the timing isn’t ideal, leaving in the middle of a school year, I believe this is the correct next step in my career. I’m simply stepping aside in order to serve where I believe I can make a greater impact. I won’t have my own classroom anymore, and that’s a very difficult thing for me at the moment. But, I’m looking forward to having my feet in many, many more classrooms as I transition into the new role. I’m excited to continue to work with everyone I’ve worked with in the past as well as people I have yet to meet.
