Setting up Rails Apps with Passenger and NGINX in CentOS, Ruby, Rails, NGINX
Deploy Rails Apps with Passenger and NGINX - CentOS
Difficulty: 2
Time: 30 minutes
Rails enables rapid application development, while NGINX is a lightweight and high performance web server. In this article, you will learn to deploy Rails application on NGINX web server using the simple and powerful features of Phusion Passenger. To perform this task, we are assuming that the user has sudo privileges.
Prerequisites
To set up your CentOS server, refer to the article: Initial Server Setup - CentOS. You need to ensure that the fully qualified domain name (FQDN) points to the server. After you have set up the CentOS server, you will need to install Ruby on Rails using RVM. You may also refer to the article: Deploy Rails Apps with Passenger and Apache - CentOS.
Install NGINX and Passenger
- Install Passenger and update all packages of the operating system.
gem install passenger
sudo yum -y update
- Install a dependency and provide the required permission to the
home
directory.
sudo yum install libcurl-devel
sudo chmod o+x "/home/UserName"
- Install NGINX passenger.
rvmsudo passenger-install-nginx-module
- For language, select
Ruby
, and then press the Enter key.
Use <space> to select. If the menu doesn't display correctly, ensure that your terminal supports UTF-8.
- Ruby
- Python
- Node.js
- Meteor
- Select
1
and press the Enter key to continue. This action downloads, compiles, and installs the NGINX files with Passenger support.
1. Yes: download, compile and install Nginx for me.(recommended)
The easiest way to get started. A stock NGINX 1.4.4 with Passenger support, but with no other additional third party modules, will be installed for you to a directory of your choice.
- Save and exit.
wq!
Set up a test Rails application
- Create a directory
sudo mkdir -p /var/www
- Provide all required permissions, and then go to that directory.
sudo chmod -R 0777 /var/www/
cd /var/www
- Create a Rail application, and then go to
application
directory.
rails new HelloWorld
cd HelloWorld
- Create a sample databases, and then generate a scaffold controller to manage the production database.
RAILS_ENV=development rake db:migrate
RAILS_ENV=production rake db:migrate
rails generate scaffold Task title:string note:text
- Test your application by running the following command in the application directory:
ruby -s
Configure NGINX
- Open the following configuration file of NGINX.
sudo vim /etc/nginx/conf/nginx.conf
- Uncomment the following line:
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/deploy/.rbenv/shims/ruby; # If you use rbenv
- Add the following line in this file:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
server_name mydomain.com; //your server name
passenger_enabled on;
rails_env production;
root/home/deploy/myapp/current/public; //Rails application path
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html
{
root html;
}
}
- Save and exit.
wq!
- Restart the NGINX service.
sudo service nginx restart
Conclusion
In this article, we reviewed the steps involved in installing Ruby on Rails using RVM, installed NGINX and Passenger, and finally compiled and configured it to deploy our Rails application on NGINX web server.


The sample application provides a mechanism to view and compare items with duration, and single events, against time. It presents a set of features to promote quick understanding of the high level picture as well as the identification of causal-effect relationships and trends. This control could be used to convey information either to the patient or to the clinician.
The Timeline Control is implemented by hosting and configuring the application code in a Microsoft Health CUI compliant manner.
Additional information relating to this control can be found on the corresponding MSCUI control page.

System-Wide Repository (Windows only) |
Previous to this release, when a new JRE was installed, JAR and native libraries for the old release were not visible to the new one. Thus applications and applets that relied on those libraries would not work, and developers were forced to redeploy their libraries to the new JRE. The new System-Wide Repository is the solution to that problem. It provides a global or system-wide location where the VM can search for libraries, JAR or native, indepenent of the JRE location. It provides functionality similar to the repository in the Microsoft VM (see How Does the Virtual Machine Search for Java Classes?).
Note: In this release the system-wide repository is supported only by Java Plug-in and only on Windows.
The table below shows the location of the new System-Wide Repository:
Type of Library System-Wide LocationDLL Any directory in the System Path environment variable. Untrusted JAR <Windows Directory>\Sun\Java\Deployment\Lib\Untrusted
Trusted JAR <Windows Directory>\Sun\Java\Deployment\Lib\Trusted
<Windows Directory>
is the Windows OS directory on the drive where Windows was installed (also called %SystemRoot%
).
For example, on Windows XP, where Windows has been installed on the C drive (typical), the locations of these libraries would be as follows:
Type of Library System-Wide LocationDLL Any directory in the System Path variable; e.g., C:\WINDOWS\repository
ifC:\WINDOWS\repository
has been set in the System Path variable.Untrusted JAR C:\WINDOWS\Sun\Java\Deployment\Lib\Untrusted
Trusted JAR C:\WINDOWS\Sun\Java\Deployment\Lib\Trusted
Note the following:
AllPermission
permissions, while the latter are given only default applet permissions.java.ext.dirs
.
If the user selects his/her own java.ext.dirs
system property
via the Java Control Panel, the JARs in the system-wide trusted repository will not be
loaded by Java Plug-in.


NAMESPACE\&.CONF
Section: Linux\-PAM Manual (5)Updated: 03/02/2009
Index Return to Main Contents
namespace.conf - the namespace configuration file
DESCRIPTION
The pam_namespace.so module allows setup of private namespaces with polyinstantiated directories. Directories can be polyinstantiated based on user name or, in the case of SELinux, user name, sensitivity level or complete security context. If an executable script FC/etc/security/namespace.initF[] exists, it is used to initialize the namespace every time an instance directory is set up and mounted. The script receives the polyinstantiated directory path and the instance directory path as its arguments.
The FC/etc/security/namespace.confF[] file specifies which directories are polyinstantiated, how they are polyinstantiated, how instance directories would be named, and any users for whom polyinstantiation would not be performed.
When someone logs in, the file FCnamespace.confF[] is scanned. Comments are marked by # characters. Each non comment line represents one polyinstantiated directory. The fields are separated by spaces but can be quoted by " characters also escape sequences \b, \n, and \t are recognized. The fields are as follows:
polydir instance_prefix method list_of_uids
The first field, polydir, is the absolute pathname of the directory to polyinstantiate. The special string $HOME is replaced with the user's home directory, and $USER with the username. This field cannot be blank.
The second field, instance_prefix is the string prefix used to build the pathname for the instantiation of <polydir>. Depending on the polyinstantiation method it is then appended with "instance differentiation string" to generate the final instance directory path. This directory is created if it did not exist already, and is then bind mounted on the <polydir> to provide an instance of <polydir> based on the <method> column. The special string $HOME is replaced with the user's home directory, and $USER with the username. This field cannot be blank.
The third field, method, is the method used for polyinstantiation. It can take these values; "user" for polyinstantiation based on user name, "level" for polyinstantiation based on process MLS level and user name, "context" for polyinstantiation based on process security context and user name, "tmpfs" for mounting tmpfs filesystem as an instance dir, and "tmpdir" for creating temporary directory as an instance dir which is removed when the user's session is closed. Methods "context" and "level" are only available with SELinux. This field cannot be blank.
The fourth field, list_of_uids, is a comma separated list of user names for whom the polyinstantiation is not performed. If left blank, polyinstantiation will be performed for all users. If the list is preceded with a single "~" character, polyinstantiation is performed only for users in the list.
The method field can contain also following optional flags separated by : characters.
create=mode,owner,group - create the polyinstantiated directory. The mode, owner and group parameters are optional. The default for mode is determined by umask, the default owner is the user whose session is opened, the default group is the primary group of the user.
iscript=path - path to the instance directory init script. The base directory for relative paths is FC/etc/security/namespace.dF[].
noinit - instance directory init script will not be executed.
shared - the instance directories for "context" and "level" methods will not contain the user name and will be shared among all users.
The directory where polyinstantiated instances are to be created, must exist and must have, by default, the mode of 0000. The requirement that the instance parent be of mode 0000 can be overridden with the command line option ignore_instance_parent_mode
In case of context or level polyinstantiation the SELinux context which is used for polyinstantiation is the context used for executing a new process as obtained by getexeccon. This context must be set by the calling application or FCpam_selinux.soF[] module. If this context is not set the polyinstatiation will be based just on user name.
The "instance differentiation string" is <user name> for "user" method and <user name>_<raw directory context> for "context" and "level" methods. If the whole string is too long the end of it is replaced with md5sum of itself. Also when command line option gen_hash is used the whole string is replaced with md5sum of itself.
EXAMPLES
These are some example lines which might be specified in FC/etc/security/namespace.confF[].
-
# The following three lines will polyinstantiate /tmp, # /var/tmp and user's home directories. /tmp and /var/tmp # will be polyinstantiated based on the security level # as well as user name, whereas home directory will be # polyinstantiated based on the full security context and user name. # Polyinstantiation will not be performed for user root # and adm for directories /tmp and /var/tmp, whereas home # directories will be polyinstantiated for all users. # # Note that instance directories do not have to reside inside # the polyinstantiated directory. In the examples below, # instances of /tmp will be created in /tmp-inst directory, # where as instances of /var/tmp and users home directories # will reside within the directories that are being # polyinstantiated. # /tmp /tmp-inst/ level root,adm /var/tmp /var/tmp/tmp-inst/ level root,adm $HOME $HOME/$USER.inst/inst- context
For the <service>s you need polyinstantiation (login for example) put the following line in /etc/pam.d/<service> as the last line for session group:
session required pam_namespace.so [arguments]
This module also depends on pam_selinux.so setting the context.

During our time in the hospital, the staff would always tell us, "Take care of yourselves, so you can take care of Emma." As great as that sounds, we did what any parent would do - we sacrificed anything for Emma. This sacrifice looks different to many, but often includes time, food, sleep, and general hygiene to be there for your child. Our mom boxes contain makeup and skin-care products, which are items that don't even make the list when your focus is on your child, and you're rushing around to pack things for the hospital stay.Emma's Hope Mom Boxes
The Need
“As someone who has been there, I know first hand just how uplifting it can be to simply wash my face and put on moisturizer and mascara. It helped me feel more put together, and in a small way, it helped me mentally feel that I was better able to care for Emma because I felt good about myself.”
— Jane (Emma's Mom)
These mom boxes are filled with a variety of skin-care, makeup, and wellness products:
We are honored and blessed to be able to provide mothers whose children are undergoing treatment for a life-threatening illness or cancer and are currently admitted to the hospital with these boxes, as a small, tangible gesture of love and hope.
Donate To a Mom Box NowWe are also extraordinarily grateful to the businesses who have partnered with us to provide certain products for these mom boxes. Thank you!


fuzzyPEACH: Fuzzy Logic Simulation of Deltaic Deposition
As an undergraduate, I took over development of a MATLAB tool called fuzzyPEACH (Fuzzy Predictive Earth Analysis Constrained by Heuristics). Originally written by Dr. Jeffrey Warren as a way to simulate stratigraphic architecture developed in deltaic depositional systems on passive margins (e.g., the East China Sea), my job was to update the model to better represent more diverse systems.
Below is the poster I presented at the 2016 Anadarko Research Symposium at UNC.

Under Construction: Try nav bar!
Under Construction: Try nav bar!
My journey, like many, began on the Oregon Trail, a step behind the rippling red trench coat of Carmen Sandiego, inside a classroom during recess inserting the floppiest of floppy disks into an old Apple IIe. I died a gumshoe stricken with dysentery out there on the range, but I was reborn with code running through my veins, a ten year old Neo, a new world open to me. I scrounged up ten dollars and bought my own Apple IIe at a rummage sale.
No one is quite certain about what happened next. Some say I died off the coast of Chile in a geographically unlikely waterspout, while others claim the American School System in the 90s was unhelpful in encouraging a child's interest in tech, and for a time I languished in an unrelated field. Whatever the case, after spending ten years working in media as a videographer and video editor, a move to Chicago gave me the opportunity to get back on that horse, and I am off galloping.
At Dev Bootcamp here in Chicago, I reconnected with my childlike curiosity about coding. I've taken all the creativity and passion I put into video editing and found it all operates exactly the same in the world of software development. I've rediscovered a passion for learning everything that I can about the field, which is vast. Lastly, I've found a real life Carmen Sandiego: a life-long pursuit of excellence where I'll learn a thing or two and have a blast along the way.
My work style is efficient, thorough, focused, and results-driven. My colleagues describe me as adaptable, resourceful, consistent, and eager to both get a laugh and the job done. I strongly value honesty, excellence, collaboration, and loyalty.
And, if you’re interested, my Myers-Briggs is INFP.

Before I was a web developer, I worked in media. Here are a few projects I shot and edited over the past 10 years!
The City of Paris from Michael Pintar on Vimeo.
Los Angeles City Video from Michael Pintar on Vimeo.
Berlin Bar: The Green Door from Michael Pintar on Vimeo.
Hewlett Packard Unpacked: Billy Galaxy from Michael Pintar on Vimeo.
VEVO: NERD from Michael Pintar on Vimeo.
Men's Health Trends from Michael Pintar on Vimeo.
Duckies is a game based off of the popular "2048" and was a solo challenge I completed at DevBootcamp. It was one of the first javascript projects I undertook with emphasis on Object-oriented programming. As an extended challenge to myself I opted out of storing the values in a nested array, and instead stored them in one long array. The final code could use a refactor, but I believe it illustrates solid OOP.

For complex-valued glorot [GLOROT-2010] or He [HE-2015] initialization, one can not simply initialize real and complex part separately or one will not have the variance restrictions presented on the papers and therefore will lose its good properties. The theory on how to implement the initialization can be found in [TRABELESI-2017] section 3.6.

Hey Scarlett,
Well, the way they make shows is, they make one show. That show's called a pilot. Then they show that show to the people who make shows, and on the strength of that one show they decide if they're going to make more shows. Some pilots get picked and become television programs. Some don't, become nothing. She starred in one of the ones that became nothing.
Now that there is the Tec-9, a crappy spray gun from South Miami. This gun is advertised as the most popular gun in American crime. Do you believe that shit? It actually says that in the little book that comes with it: the most popular gun in American crime.
You don't get sick!
Your bones don't break, mine do. That's clear. Your cells react to bacteria and viruses
differently than mine. You don't get sick, I do. That's also clear. But for some reason,
you and I react the exact same way to water. We swallow it too fast, we choke. We get some
in our lungs, we drown. However unreal it may seem, we are connected, you and I. We're on
the same curve, just on opposite ends.

Devon pub named most dog-friendly in the South West
Four Devon pubs made the top ten
by Jamie HawkinsA Devon pub has been named as the most dog-friendly in the south west.
The Ship Inn, Teignmouth has been declared the regional winner of Rover’s coveted Dog-friendly Pub Awards, after receiving the most votes from the public in the area.
The seaside pub fought off fierce competition this year from over 335 dog-friendly watering holes across the South West, but held on to the top spot after accumulating the most votes.
Locally renowned as a great pit stop after a nice long dog-walk, the pub is hailed for its welcoming approach, and dog amenities, including treats, secure garden and quiet areas.
Ellie Cameron from The Ship Inn was delighted with the news.
She said: “It’s really lovely that being dog-friendly is a recognised feature of this pub. To be the most dog-friendly pub in our region is amazing as we know there were many to choose from, but we were lucky enough this year to take the crown.
"It's shown us how supportive our customers are and that is something truly heartwarming.
“It's important to us, as a pub, that we are dog friendly because we understand and value how much our customers pets mean to them, and how nice it is to share that part of their life with them.”
Three other Devon pubs made the top ten:
- The Ship Inn, Teignmouth
- The Halzephron Inn, Gunwalloe
- The Swan Inn, Sidmouth
- The Fox and Hounds, Devizes
- Henry’s Bar, Paignton
- The Royal Oak, Exeter
- The White Hart, Melksham
- The Blue Anchor, Teignmouth
- The Mason’s Arms, Yeovil
- The Royal Oak Hotel, Yeovil
An extensive database of dog-friendly pubs in the South West is available for perusal by punters and pups at pubs.rover.com .
Simon Le Grice from Rover said, “The South West has a fantastic array of dog-friendly pubs for locals to choose from. It’s been wonderful to see so many of them represented in this year’s awards. The community has really got behind their favourite pubs and helped us, for the fourth year running, to find the best of the bunch - and with the The Ship Inn at Teignmouth, we’ve found just that.
“The superb service they demonstrated shows a real consideration for dog welfare and happiness, which we at Rover value above all. The whole Rover pack is proud to congratulate The Ship Inn on winning the Dog-friendly Pub Award for the South West and hopes that the awards will inspire dog owners country-wide to discover and support their local pubs, while also encouraging more pubs to consider our two-legged friends in their offerings.”
The Ship Inn is one of 12 regional finalists in this year’s nationwide Dog-friendly Pub Awards. Chosen from the regional finalists, the national winner, The Fox & Hounds in Theale was selected by a panel of judges from Rover, RSPCA, The Morning Advertiser, Your Dog Magazine and The Guardian.

Q. What ths difference between MP3 and AAC files?
A. AAC is a newer format that boasts higher musical fidelity than MP3s at the same bittrate—in other words, AAC files simply sound better. AAC files are compatible with nearly all recent digital music players and operating systems, including all iPods and iPhones, as well as players from Creative, Microsoft and Sony, among others. MP3s are sonically inferior, though are compatible with a broader range of music players. It would be wise to make sure your player can play AAC files before choosing them over MP3—here is an incomplete list of some hardware that supports AAC. Also worth noting—you can easily re-encode AAC files to MP3s, if you need MP3 versions at a later date, using free music managment software such as Apple's iTunes.
Q. When do I get to download the music I just bought?
A. The music download is available instantly after you complete the order.
Q. How do I open this ZIP file I just downloaded?
A. Our music downloads are packaged into zipped archives (with .zip at the end of the file name) to ensure a trouble-free download. In Windows XP, Vista and Mac OS X, opening a zipped file is as simple as double clicking it. If you are having difficulties, we'll let the Tech Pros guide you thorugh it.
Q. My secret code for the download isn't working. Help!
A.  We are here to help. Email us at<EMAIL_ADDRESS>and include your order #, which operating system and web browser you are using, and the exact problem encountered in downloading, and we'll get it working before you know it.

--- layout: single author_profile: true title: 'About Me' ---
I am a Data Scientist/Algorithm Engineer at the Maps Team in Shopee with a PhD doctorate from the Singapore University of Technology and Design.
I have extensive experience developing and deploying highly performant and scalable autocomplete and ranking systems to support map search services in Southeast Asia's largest E-commerce company. I also possess first-hand experience conducting A/B tests and have developed highly robust data engineering pipelines capable of processing millions of user tracker data collected on a daily basis.
Prior to entering the industry, my primary research focus was on applying various machine learning techniques, such as active learning, deep generative imputation models, and deep reinforcement learning to tackle a wide range of data issues frequently encountered in urban freight studies. Some of these issues include data sparsity, data imbalance, incomplete data, and datasets with high annotation costs. As an ex-researcher in the Sustainable Urban Mobility Research Laboratory, I also regularly worked with heterogeneous datasets such as GPS traces, digital travel surveys, and geographic points of interest data to study urban freight activity in an urban setting.
I am currently looking for full-time job opportunities for the following roles: Data Scientist, Algorithm Engineer, Machine Learning Engineer, and Research Scientist. Please feel free to connect with me if you have any relevant opportunities!
Please feel free to contact me at (+65) 9726 1640 or via e-mail at iamraymondlow@gmail.com.

Filter.im is a web application that allows you to upload an image and apply image filters to it. The filtering effect is achieved by 2D image convolution. Available transformation effects include edge detection, sharpening, embossing, blurring, etc.
Image convolution is a two-dimensional convolution operation in image processing. It is a favored technique used in image processing and object detection.
The convolution process onto an image applies a kernel over each pixel and its local neighbors across the entire image. The kernel is a square matrix of values to determine the transformation effect on an image
Many mathematical theories and models can be achieved using image convolution. These models can be executed in matrix form for digital image processing, recognized as image convolution kernel.


Set the list of visible devices.
tf.compat.v1.config.experimental.set_visible_devices
tf.compat.v2.config.experimental.set_visible_devices
tf.config.experimental.set_visible_devices( devices, device_type=None )
Sets the list of PhysicalDevices to be marked as visible to the runtime. Any devices that are not marked as visible means TensorFlow will not allocate memory on it and will not be able to place any operations on it as no LogicalDevice will be created on it. By default all discovered devices are marked as visible.
The following example demonstrates disabling the first GPU on the machine.
physical_devices = config.experimental.list_physical_devices('GPU') assert len(physical_devices) > 0, "Not enough GPU hardware devices available" # Disable first GPU tf.config.experimental.set_visible_devices(physical_devices[1:], 'GPU') logical_devices = config.experimental.list_logical_devices('GPU') # Logical device was not created for first GPU assert len(logical_devices) == len(physical_devices) - 1
devices
: (optional) List of PhysicalDevice objects to make visibledevice_type
: (optional) Device types to limit visibility configuration to.
Other device types will be left unaltered.


Exquisite Corpse
Once upon a time, there was a beautiful princess.
She even had a pink pony. How cool is that? But one day... her pony turned evil.
The princess was riding her pony through the forest to the lake, when suddenly her pony bucked her off and ran away.
The princess was left all by herself in the forest and had no idea how to get home.
The princess decdied to walk in the direction of the lake, but ended up walking in the direction of the evil dragons lair. The Dragons lair was surounded by a small moat, inhabited by many frogs. One of these frogs was different though, it reminded her of someone, and happened to be wearing what seemed to resemble a crown.
The princess reached her hand toward the frog. But the frog ran away. She traced the frog through the forest and into another pile of frogs. To catch the special frog, princess swim through the pool of frogs and found an entrance to the outer space.

These Are The Top 10 Best 10mm Pistols in 2019
We have the list.
by Gun News DailyKey point: It all comes down to needs and preferences.
Many gun aficionados have heralded the 9mm handgun as the ideal self-defense firearm, but despite its popularity, the “nine milli” is not the only worthy choice available.
On the contrary, the 10mm is making a big comeback and it’s got just as many excellent attributes as its counterpart.
First developed in 1983 thanks, in part, to the concerted efforts of the FBI and the Smith & Wesson gun company.
The 10mm is a rimless large pistol with a maximum pressure of 33,000 psi that has some serious power.
The findings of multiple ballistic gel tests found that the 10mm could travel more than 17 inches after impact whereas the 9mm could only travel 13 inches after impact.
In other words, a 10mm could penetrate two people at center mass and continue traveling.
While the 10mm fell by the wayside for many years, recent advances in metallurgy have resulted in a surge in popularity. Modern pistol models are better equipped to handle the 10mm caliber than those built in the 1980s.
Today, we’re going to take a look our my top picks for best 10mm pistols.
For each, we’ll discuss what makes them a worthwhile purchase and why the 10mm is every bit as ideal a handgun as its nemesis, the nine millimeter.
Are you ready? Let’s get started.
THINGS TO CONSIDER BEFORE PURCHASING A 10MM PISTOL
To recap what we’ve already gone over in summary above, there are several considerations a gun owner should contemplate before making a 10mm pistol purchase.
The key factors to think about when selecting the weapon for your personal needs are durability, price point and reliability.
10MM PISTOL ACCESSORIES
A lot of people think that gun accessories only apply to larger firearms like rifles and shotguns, but there are plenty of accessories for handguns as well.
Beretta offers a variety of handgun accessories including custom grips, lasers and lights, rear and front sights and magazines.
You’ll want to confirm how many rounds your 10mm pistol can hold before purchasing any magazines from such manufacturers.
I’m a big proponent of lasers and lights since they can enable the shooter to fire in any environment, whether it’s day or night.
Cabela’s carries my absolute favorite light, the Trijicon RMR Adjustable LED Reflex Sight. It’s a tad expensive at $349.00, but it’s worthy every penny.
You get a true-color multi-coated lens and eight adjustable brightness settings as well as a tritium phosphor lamp. The best part is, it’s powered by a single lithium battery. Each unit also comes with a lifetime warranty from the manufacturer.
SELECTING YOUR AMMO
Ammunition is every bit as important as the gun from which you fire it. The 10mm caliber is garnering a long-awaited and well-earned reputation among gun consumers, but brands and styles are an integral part of the shooting process.
Today, 10mm ammo is designed to make its forebears proud with 135 to 180 grain range that’s controllable and precise, providing the user excellent stopping power and ballistics.
There is much debate among the online community as to which ammo is the best ammo for a 10mm handgun, but the general consensus seems to be this: You don’t want a load that tops out at the teetering edge of SAAMI specs, but you also don’t want something like a 230 grain load which will penetrate too deeply in a defensive situation.
You want ammunition that will fire cleanly from your firearm every time and you want each round to be accurate.
People seem to underestimate the 10mm pistol, perhaps because of its checkered past. But the truth is, it can do a lot of damage with very little. For this reason, a fairly mediocre bullet like a 165 grain Montana Gold can produce a substantial wound.
Here’s a short list of some of the best ammo out there for a 10mm pistol:
- Underwood 165 grain Gold Dot
- Hornady 175 grain Critical Duty
- Reed’s 180 grain Golden Saber
All of these loads will let you take care of business with varying degrees of penetration and performance, but none of them will let you down.
Keeping these tips in mind, let’s take a look at the top ten 10mm’s, and what makes them uniqu
COLT DELTA ELITE
This government model is at the top of the heap when it comes to ten-millimeter semi-automatic handguns. Colt was one of the original pioneers of the ten milli and they’ve only gotten better with time.
This combat pistol blows away much of the competition because it’s got enough power for medium size game hunting in addition to CQC (Close Quarters Combat).
Each one comes with Novak sights with dots, an enhanced hammer, wide slide serration, a lowered ejection port and an upswept beavertail grip safety.
At $1,099, the Delta Elite is a bit more affordable than some of its counterparts and you’ll know that you are paying for quality engineering and a durable build.
DAN WESSON RZ-10
This 1911 model has a Clark-style target rib machined on the top of the slide with defensive sights.
The Razoback‘s got a pair of sexy double diamond Cocobolo grips that are a nice touch for collectors.
This is another one that’s on the pricey side at $1,499.99, but it’s a high-performance single action pistol that is known for never jamming and never disappointing.
EAA WITNESS P CARRY
This is a great option for those looking for a carry gun. It’s a low profile weapon with snag resistant sights and a stainless steel slide.
Unlike some other models, the Witness features a magazine that can hold 15 rounds. It’s got a one-piece full size polymer grip and an automatic firing pin block.
You won’t find the Witness at Cabela’s or 1800gunsandammo.com, but Cheaper Than Dirt sells them for $548.96.
GLOCK FLAT DARK EARTH GEN 4 FULL-SIZE PISTOL
This one is an aesthetic marvel and a shrewd one at that. If you’re looking for cover and you’re in an outdoor combat situation, this is the 10mm pistol you want to have on your hip.
Its forest green body is but one of the Gen 4’s terrific features. Built for performance and durability, the Dark Earth Gen 4 has fixed sights, a shiny finish and an enlarged, reversible magazine release.
Each FDE Gen 4 comes with three customizable backstraps and three magazines. Its RTF (Rough Textured Frame) makes it easy to handle.
Perhaps second only to its discreet color is its price point. Cabela’s offers the Glock FDE Gen 4 for just $599.99. When you consider the rising prices on most full-size pistol models, this one’s an absolute steal.
KIMBER ECLIPSE CUSTOM II
This 1911 pistol is a two-tone handgun with stainless steel match-grade barrels and bushings.
Each one comes with full size grips, a chamber indicator port, high-ride beavertail grip safety and an extended thumb safety. The Commander-style hammer and checkered side release are also quite appealing to most avid shooters.
It’s also got a brushed polished carbon slide and rosewood grips, making it one of the more attractive ten millis on the market. This one is famed for its hair-splitting accuracy and precision design.
You can usually get your hands on one for less than $700. Cabela’s has a few on sale for $699.99. They also offer a Kimber Eclipse Custom kit with a discount price of $949.99. It comes with a handsome leather holster, an aligner insert and eight-round KimPro TacMag magazines.
PARA USA ELITE LS HUNTER
This one’s got all the bells and whistles you want in a 10mm handgun from its adjustable rear target sight and green fiber optic front to its six-inch ramped barrel and beavertail grip safety.
It’s a high-end variation on the 1911 that comes with a bevy of unique features including VZ Operator machined G10 grips, oversized, flared ejection port, and an EGW HD Extractor.
At $1,249.00, it’s not the cheapest model on my list, but it’s certainly worth every penny. Pound for pound, the Elite LS Hunter is a python compared to some of the cheaper choices available to the general public.
REMINGTON 1911 R1 SEMI-AUTOMATIC HUNTER LS
You know the expression, “What’s in a name?” Well, when it comes to Remington, the name speaks for itself. Remington has maintained a solid reputation among gun enthusiasts since 1816.
In the last 201 years, they’ve continued to improve upon each of their firearms, maintaining a position in the industry as masters of innovation and excellence.
The 1911 is no exception in terms of classic values and contemporary quality.
With a match-grade stainless barrel, serrated slide, premium grip panels and two magazines, this one’s got the works.
Cabela’s stocks the R1 starting at $649.99 while 1800gunsandammo.com has the R1 .45 with Cocobolo grips for $725.00.
ROCK ISLAND ARMORY TAC ULTRA MS
The sleek, snub-like design of the TAC Ultra MS makes it a superior pistol for conceal and carry purposes. It’s compact, ergonomic and contemporary with a modern three-slat trigger, front and rear CNC angle grooves and Piccanniny rail.

Morgan O'Leary Technical Blogs
So Youtube is one of my favorite sites because you have so much access to virtual everything. You can view anything from music videos to instructions to movies. It's also a great places to connect with people. /
My eye is drawn towards the middle and the search bar. You can see so many videos. The site visually is an organized madness. I would describe it as "cluttered", "clean", "bright", "new age", and "colorful".
This website solves the problem of sharing videos with others. I would describe the content as "entertaining", "unique", "practical", "musical", and "personalized". The focus adjectives I think fit pretty well with the visual adjectives.
It's pretty easy to find what you are looking for from the homepage. The search bar on Youtube is vital. Also when you watch a video it recommends other videos and you can click on them directly from the video you are currently watching making it super easy. Usually when I spend time on the site I feel like I am happy. I love watching comedy videos and I know I am wasting time, but the power of laughter really helps me get through the day. The site doesn't sell anything, but I do share videos quite often.
I love Elite Daily because it's an online magazine that is dedicated to people around my age. When I look at the site my eye is drawn to the header,it's black and contrasts the rest of the page. It is the most important part of the site because it directs you to the certain types of articles you would like to read.
I would describe this site visually as colorful, engaging, cluttered, inspiring, and fun. I would say it's pretty easy to find certain type of articles, but if you had a specific article in mind it would be difficult to find it if it wasn't hot currently. However, it is very easy to browse the site. Typically, when I spend some time on the site I feel more educated or entertained about what is going on. The site doesn't sell anything but again, I will share articles that I feel relate to people I know.
Again, I like this site for the articles and the hub that it provides for access to news, movies, email etc. My eye is drawn to the middle and rotating articles.
This site visually is pleasant, colorful, engaging, informative, and entertaining. This site allows people to grab articles both newsworthy, and entertaining. The content is newsworthy, entertaining, fun, practical, and light. I think these adjectives compliment the visual adjectives nicely. Usually with this site I feel either informed about the world or about new tidbits about life.

- Terminate a program using the SIGINT (interrupt) signal.


Usage of JE HA requires you to handle many different HA-specific exceptions. While some of these are Master-specific and others are Replica-specific, your code may still need to handle both. The reason why is that it is not uncommon for HA applications to have standard classes that perform database access, regardless of whether the class is used for a node in the Master state or a node in the Replica state.
The following class is an example class that can be used to perform transactional reads and writes in an HA application. This class is used by the on-disk HA examples that you can find in your JE distribution (see Replication Examples for more information). However, we think this particular example class is important enough that we also describe it here.
The RunTransaction
abstract class is
used to implement a utility class that performs database access
for HA applications. It provides all the
transaction error handling and retry framework that
is required for database access in an HA environment.
Because RunTransaction
is a class that
is meant to be used by different example HA applications, it
does not actually implement the database operations. Instead,
it provides an abstract method that must be implemented by the
HA application that uses RunTransaction
.
We begin by importing the classes that
RunTransaction
uses.
package je.rep.quote; import java.io.PrintStream; import com.sleepycat.je.EnvironmentFailureException; import com.sleepycat.je.LockConflictException; import com.sleepycat.je.OperationFailureException; import com.sleepycat.je.Transaction; import com.sleepycat.je.rep.InsufficientAcksException; import com.sleepycat.je.rep.InsufficientReplicasException; import com.sleepycat.je.rep.ReplicaConsistencyException; import com.sleepycat.je.rep.ReplicaWriteException; import com.sleepycat.je.rep.ReplicatedEnvironment;
Then we define a series of private data members that identify how our HA transactions are going to behave in the event of an error condition.
abstract class RunTransaction { /* The maximum number of times to retry the transaction. */ private static final int TRANSACTION_RETRY_MAX = 10; /* * The number of seconds to wait between retries when a sufficient * number of replicas are not available for a transaction. */ private static final int INSUFFICIENT_REPLICA_RETRY_SEC = 1; /* Amount of time to wait to let a replica catch up before * retrying. */ private static final int CONSISTENCY_RETRY_SEC = 1; /* Amount of time to wait after a lock conflict. */ private static final int LOCK_CONFLICT_RETRY_SEC = 1; private final ReplicatedEnvironment env; private final PrintStream out;
Then we implement our class constructor, which is very simple because all the heavy lifting is done by whatever application calls this utility class.
RunTransaction(ReplicatedEnvironment repEnv, PrintStream printStream) { env = repEnv; out = printStream; }
Now we implement our run()
method. This is what actually performs all the error checking and
retry work for the class.
The run()
method catches the exceptions
most likely to occur as we are reading and writing the database,
and then handles them, but it will also throw
InterruptedException and EnvironmentFailureException.
InterruptedException can be thrown if the thread calling this method is sleeping and some other thread interrupts it. The exception is possible because this method calls Thread.sleep in the retry cycle.
EnvironmentFailureException can occur both when beginning a transaction and also when committing a transaction. It means that there is something significantly wrong with the node's environment.
The readOnly
parameter for this method is
used to indicate that the transaction will only perform
database reads. When that happens, the durability guarantee for
the transaction is changed to Durability.READ_ONLY_TXN
because that policy does not call for any acknowledgements.
This eliminates the possibility of an
InsufficientReplicasException being thrown from the
Environment.beginTransaction() operation.
public void run(boolean readOnly) throws InterruptedException, EnvironmentFailureException {
Now we begin our retry loop and define our sleep cycle between retries. Initially, we do not actually sleep before retrying the transaction. However, some of the error conditions caught by this method will cause the thread to sleep before the operation is retried. After every sleep operation, the sleep time is returned to 0 because usually putting the thread to sleep is of no benefit.
OperationFailureException exception = null; boolean success = false; long sleepMillis = 0; final TransactionConfig txnConfig = readOnly ? new TransactionConfig().setDurability(Durability.READ_ONLY_TXN) : null; for (int i = 0; i < TRANSACTION_RETRY_MAX; i++) { /* Sleep before retrying. */ if (sleepMillis != 0) { Thread.sleep(sleepMillis); sleepMillis = 0; }
Now we create our transaction, perform the database operations, and
then do the work. The doTransactionWork()
method is an abstract method that must be implemented by the
application using this class. Otherwise, this is standard
transaction begin/commit code that should hold no surprises for
you.
Transaction txn = null; try { txn = env.beginTransaction(null, null); doTransactionWork(txn); /* CALL APP-SPECIFIC CODE */ txn.commit(); success = true; return;
The first error case that we check for is InsufficientReplicasException. This exception means that the Master is not in contact with enough Electable Replicas to successfully commit the transaction. It is possible that Replicas are still starting up after an application restart, so we put the thread to sleep before attempting the transaction again.
InsufficientReplicasException is thrown by Transaction.commit(), so we do have to perform the transaction all over again.
} catch (InsufficientReplicasException insufficientReplicas) { /* * Retry the transaction. Give replicas a chance to * contact this master, in case they have not had a * chance to do so following an election. */ exception = insufficientReplicas; out.printf(insufficientReplicas.toString()); sleepMillis = INSUFFICIENT_REPLICA_RETRY_SEC * 1000; continue;
Next we check for InsufficientAcksException. This exception means that the transaction has successfully committed on the Master, but not enough Electable Replicas have acknowledged the commit within the allowed period of time.
As provided here, the code considers this situation to be
an unsuccessful commit. But if you have a lot of Electable Replicas and you
have a strong durability guarantee on the Master, then you might
be able to still consider this to be a successful commit. If so,
you should set success = true;
before
returning from the method.
For more information on this error case, see Managing Acknowledgement Timeouts.
} catch (InsufficientAcksException insufficientReplicas) { /* * Transaction has been committed at this node. The * other acknowledgments may be late in arriving, * or may never arrive because the replica just * went down. */ /* * INSERT APP-SPECIFIC CODE HERE: For example, repeat * idempotent changes to ensure they went through. * * Note that 'success' is false at this point, although * some applications may consider the transaction to be * complete. */ out.println(insufficientReplicas.toString()); txn = null; return;
Next we check for ReplicaWriteException. This happens when a
write operation is attempted on a Replica. In response to this, any
number of things can be done, including reporting the problem to
the application attempting the write operation and then aborting,
to forwarding the write request to the Master. This particular
method responds to this condition based on how the
onReplicaWrite()
method is implemented.
For more information on how to handle this exception, see Managing Write Requests at a Replica.
} catch (ReplicaWriteException replicaWrite) { /* * Attempted a modification while in the Replica * state. * * CALL APP-SPECIFIC CODE HERE: Cannot accomplish * the changes on this node, redirect the write to * the new master and retry the transaction there. * This could be done by forwarding the request to * the master here, or by returning an error to the * requester and retrying the request at a higher * level. */ onReplicaWrite(replicaWrite); return;
Now we check for LockConflictException, which is thrown whenever a transaction experiences a lock conflict with another thread. Note that by catching this exception, we are also catching the LockPreemptedException, which happens whenever the underlying HA code "steals" a lock from an application transaction. The most common cause of this is when the HA replication stream is updating a Replica, and the Replica is holding a read lock that the replication stream requires.
Here, it is useful to sleep for a period of time before retrying the transaction.
} catch (LockConflictException lockConflict) { /* * Retry the transaction. Note that LockConflictException * covers the HA LockPreemptedException. */ exception = lockConflict; out.println(lockConflict.toString()); sleepMillis = LOCK_CONFLICT_RETRY_SEC * 1000; continue;
The last error we check for is ReplicaConsistencyException. This
exception can be thrown when the transaction begins. It means that
the beginTransaction()
method has waited
too long for the Replica to catch up relative to the Master. This
situation does not really represent a failed transaction because
the transaction never had a chance to proceed in the first place.
In any case, the proper thing to do is to put the thread to sleep for a period of time so that the Replica has the chance to meet its consistency requirements. Then we retry the transaction.
Note that at this point in time, the transaction handle is in
whatever state it was in when beginTransaction()
was called. If the handle was in the null state before
attempting the operation, then it will still be in the null
state. The important thing to realize here is that the
transaction does not have to be aborted, because the
transaction never began in the first place.
For more information on consistency policies, see Managing Consistency.
} catch (ReplicaConsistencyException replicaConsistency) { /* * Retry the transaction. The timeout associated with * the ReplicaConsistencyPolicy may need to be * relaxed if it's too stringent. */ exception = replicaConsistency; out.println(replicaConsistency.toString()); sleepMillis = CONSISTENCY_RETRY_SEC * 1000; continue;
Finally, we abort our transaction and loop again as needed.
onRetryFailure()
is called if the
transaction has been retried too many times (as defined by
TRANSACTION_RETRY_MAX
. It provides the option to
log the situation.
} finally { if (!success) { if (txn != null) { txn.abort(); } /* * INSERT APP-SPECIFIC CODE HERE: Perform any * app-specific cleanup. */ } } } /* * CALL APP-SPECIFIC CODE HERE: * Transaction failed, despite retries. */ onRetryFailure(exception); }
Having done that, the class is almost completed. Left to do is to define a couple of methods, one of which is an abstract method that must be implemented by the application that uses this class.
doTransactionWork()
is an abstract method
where the actual database operations are performed.
onReplicaWrite()
is a method that should be
implemented by the HA application that uses this class. It is used to
define whatever action the Replica should
take if a write is attempted on it. For examples of how this is
used, see the next section.
For this implementation of the class, we simply throw the ReplicaWriteException that got us here in the first place.
abstract void doTransactionWork(Transaction txn); void onReplicaWrite(ReplicaWriteException replicaWrite) { throw replicaWrite; }
Finally, we implement onRetryFailure()
,
which is what this class does if the transaction retry loop
goes through too many iterations. Here, we simply print the error
to the console. A more robust application should probably write the
error to the application logs.
void onRetryFailure(OperationFailureException lastException) { out.println("Failed despite retries." + ((lastException == null) ? "" : " Encountered exception:" + lastException)); } }
Having implemented the RunTransaction
class, it is fairly easy to use.
Essentially, you only have to implement the
RunTransaction.doTransactionWork()
method so that it performs whatever database access you
want.
For example, the following method performs a read on an
EntityStore used by the StockQuotes example HA
application. Notice that the class is instantiated,
doTransactionWork()
is
implemented, and the RunTransaction.run()
method are all called in one place. This makes for fairly
easy maintenance of the code.
private void printStocks(final PrintStream out) throws InterruptedException { new RunTransaction(repEnv, out) { @Override void doTransactionWork(Transaction txn) { // dao is a DataAccessor class used to access // an entity store. final EntityCursor<Quote> quotes = dao.quoteById.entities(txn, null); try { out.println("\tSymbol\tPrice"); out.println("\t======\t====="); int count = 0; for (Quote quote : quotes) { out.println("\t" + quote.stockSymbol + "\t" + quote.lastTrade); count++; } out.println("\n\t" + count + " stock" + ((count == 1) ? "" : "s") + " listed.\n"); } finally { quotes.close(); } } }.run(true /*readOnly*/); /* Output local indication of processing. */ System.out.println("Processed print request"); }
In the previous example, we do not bother to override the
RunTransaction.onReplicaWrite()
method because this transaction is performing read-only
access to the database. Regardless of whether the
transaction is run on a Master or a Replica,
ReplicaWriteException can not be raised here, so we can
safely use the default implementation.
However, if we were running a transaction that performs a
database write, then we should probably do something with
onReplicaWrite()
other than merely
re-throwing the exception.
The following is an example usage of
RunTransaction
that is also used in
the StockQuotes example.
void updateStock(final String line, final PrintStream printStream) throws InterruptedException { // Quote is a utility class used to parse a line of input // obtained from the console. final Quote quote = QuoteUtil.parseQuote(line); if (quote == null) { return; } new RunTransaction(repEnv, printStream) { void doTransactionWork(Transaction txn) { // dao is a Data Accessor class used to perform access // to the entity store. dao.quoteById.put(txn, quote); /* Output local indication of processing. */ System.out.println("Processed update request: " + line); } // For this example, we simply log the error condition. // For a more robust example, so other action might be // taken; for example, log the situation and then route // the write request to the Master. void onReplicaWrite(ReplicaWriteException replicaWrite) { /* Attempted a modification while in the replica state. */ printStream.println (repEnv.getNodeName() + " is not currently the master. Perform the update" + " at the node that's currently the master."); } }.run(false /*not readOnly */); }

This tool will make delete user-specified input raster or vector data sets, including all associated files.
The following is an example of a Python script using this tool:
wd = pluginHost.getWorkingDirectory()
# You may have multiple input files but they must
# be separated by semicolons in the string.
inputFiles = wd + "input1.dep" + ";" + wd + "input2.dep" + ";" + wd + "input3.dep"
args = [inputFiles]
pluginHost.runPlugin("DeleteFiles", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
// You may have multiple input files but they must
// be separated by semicolons in the string.
def inputFiles = wd + "input1.dep" + ";" + wd + "input2.dep" + ";" + wd + "input3.dep"
String[] args = [inputFiles]
pluginHost.runPlugin("DeleteFiles", args, false)
