Regulate Your Finances
Know your household’s monthly income, the amount spent on bills and the average spent on entertainment and miscellaneous purchases. Knowing the exact amounts that are added and extracted from your bank account each month helps you save on overdraft fees and unexpected payments. For example, say your family’s monthly income is $3,100. Let’s say your bills amount to $2,200; leaving you with $900 extra to play with each month. Budget approximately $300 for activities and entertainment and you’re left with $600. Sure, you can buy a pair of shoes and a set of golf clubs every now and then, but your money is put to better use earning interest in a savings account.

SQUID CONFIGURATION

First I changed log format of squid access logs file by editing squid’s configuration file usually located at /etc/squid/squid.conf

vi /etc/squid/squid.conf

Then search for “logformat” I configured my squid server’s log format to something  looks like this:

logformat custom %{%Y-%m-%d %H:%M:%S}tl,%tr,%>a,%>A,%rm,%ru,%{Content-Length}h,%{User-Agent}>h

Where, custom is a name for this format. This format will provide me following information (separated by comma):

date,response time(millisec),user ip,user host,request method,request url,file size,downloaded size,squid status,referer,user-agent

Note:You can change log format to whatever you want. After changing log format, now search for “access_log” and modify logformat name to what you have given above. In my case, its “custom” so:

access_log /var/log/squid/access.log custom

Where,

access_log is a syntax to configure squid access logs.

/var/log/squid/access.log is the path for squid access logs file.

custom is the name for logformat we’ve just created. Squid configuration is now complete.

SYSLOG-NG CONFIGURATION

I am not covering how to install syslog-ng, so, we are moving now to syslog-ng configuration.

NOTE: Install libdbi-mysql package along with syslog-ng, or else, syslog-ng wont send logs to mysql server.

Open sysnlog-ng configuration file, usually located at /etc/syslog-ng/syslog-ng.conf

Syslog-ng configuration is divided into three parts, i.e. SOURCE, DESTINATION, and PARSER.

First, we will create data source for syslog-ng, which is squid.

Write this (syslog-ng.conf):

source all { file("/var/log/squid/access.log"); };

Where,

source is the syntax to define a data source.

all is the name for this data source we are creating. You can name it anything.

file(“/var/log/squid/access.log”) is the source file where access logs are located. Now we will configure destination.

NOTE:Before configuring destination, what we need to understand is how syslog-ng interpret data and assign them into variables? Syslog-ng have its own default variables it assigned by automatically inspecting data source, but we are going to define our own variables. Write this (in syslog-ng.conf):

destination d_mysql {  
sql(type(mysql) 
host("db.example.org") 
username("db_username") 
password("db_password") 
database("syslog") 
table("squid") 
columns("date", "responsetime", "userip", "userhost", "requestmethod", 
"requesturl",  "filesize", "downloaded", "squidstatus", "referer", "useragent") 
values("$YEAR-$MONTH-$DAY $SQDATE", "$SQRESPONSETIME", "$SQUSERIP", "$SQUSERHOST", 
"$SQREQUESTMETHOD",  "$SQREQUESTURL", "$SQFILESIZE", "$SQDOWNLOAD") };

Where,

destination is a syntax to define data destination.

d_mysql is the name for this destination

sql type is a type of database

columns are table’s fields

values are the variables syslog-ng will assign data in.

Now we are going to define parser so that syslog-ng can understand squid log format and assigned them in respective variables.

Note:This is where we will create our own variables.

Write this (in syslog-ng.conf):

parser p_squid {  
csv-parser(columns( "SQDATE", "SQRESPONSETIME", "SQUSERIP", "SQUSERHOST", 
"SQREQUESTMETHOD",  "SQREQUESTURL", "SQFILESIZE", "SQDOWNLOADED", 
"SQSQUIDSTATUS", "SQREFERER", "SQUSERAGENT") 
flags(escape-none) 
delimiters(",") 
quote-pairs('""[]') 
); };

Where,

parser is the syntax for defining parser.

p_squid is the name for parser.

csv-parser(columns( are the variables we want syslog-ng to grab data in.

delimitersare simply column delimiter, which is in our case comma.

Finally, we will join these 3 to make this thing work. Write this (in syslog-ng.conf):

log { source(all); parser(p_squid); destination(d_mysql); };

where,

all is the name of our data source

p_squid is the name of parser

d_mysql is the name of destination

MYSQL DATABASE CONFIGURATION

Now, as our final step, we will create database for syslog-ng with a table.

Login to mysql and run these commands in this sequence:

create database syslog;
CREATE TABLE IF NOT EXISTS `squid` (
 `serial` int(11) NOT NULL AUTO_INCREMENT,
 `date` text NOT NULL,
 `responsetime` text NOT NULL,
 `userip` text NOT NULL,
 `userhost` text NOT NULL,
 `requestmethod` text NOT NULL,
 `requesturl` text NOT NULL,
 `filesize` text NOT NULL,
 `downloaded` text NOT NULL,
 `squidstatus` text NOT NULL,
 `referer` text NOT NULL,
 `useragent` text NOT NULL,
 PRIMARY KEY (`serial`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=36 ;

This is it. Now restart squid, and then syslog-ng service, and check syslog-ng logs for possible errors by typing this command:

tail -f /var/log/syslog

That’s all :) Please give your feed back in comments, Thank you.

Optical Image Stabilization

• Optical image stabilization refers to any stabilization method, whether lens-based or sensor-based, that uses the optics of the camera to compensate for small vibrations, which can become amplified when shooting in low light or with a telephoto lens. Digital image stabilization refers to stabilization methods using software to detect and compensate for shaky motion between images. This means that while optical stabilization is available in still and video cameras, digital stabilization is only useful for digital video.

Lens-Based Stabilization

• Often considered synonymous with optical image stabilization, lens-based image stabilization applies minute adjustments to the camera’s lens when gyroscopic sensors detect vibration. This form of stabilization is built into the lens itself, and can vary depending on the lens type and manufacturer. This also means that you can upgrade to a lens with better image stabilization capability. Lens-based stabilization is the only form of image stabilization currently available in film cameras.

Sensor-Shift Stabilization

• Instead of adjusting the lens, a camera using sensor-shift stabilization adjusts the digital image sensor to compensate for shake. Like lens-based stabilization, this method uses gyroscopic sensors to detect vibration. This method is built into the body of the camera and is independent of the lens. Corrections using sensor-shift stabilization are not visible in the viewfinder of most cameras and can only be viewed after taking the photo, while lens-based stabilization is visible through the viewfinder.

Comparison

• Tests have shown that lens-based image stabilization is generally superior to the sensor-shift method, making possible slower shutter speeds and better low-light photography. Popular Photography magazine found that one image-stabilized lens offered up to four f-stops of shutter speed less than a lens without stabilization. While these optical stabilization methods compensate independently for motion and can’t be used simultaneously, a camera using switchable sensor-shift technology would ensure at least a degree of image stabilization when a stabilized lens isn’t in use.

• Eleven case studies provide insightful, empirical data from real-world organizations
• Provides a broad view across organizational settings and factors, such as personnel, and technical environments, including cloud, Agile, and open source options
• Illuminates the hard-won lessons, tradeoffs, and impacts—with advice on how to engineer successful, sustainable changes yourself
