Keep your camera in manual mode to take great pictures


One can master the art of photography only when they have a complete understanding of the camera settings. Different cameras offer different functions. You cannot use a single setting for every type of photography. Many times you are required to change settings according to the situation. You can click great pictures when you have control over the settings of your camera.

Key elements in camera settings

  • Aperture: Aperture is the iris of the lens through which the light passes. More light passes with a wider aperture and vice versa. It is the first setting that determines how much is in focus.
  • Shutter speed: The light reaches the shutter once it passes through the lens. Shutter speed allows you to decide the amount of light that you allow in the camera. Different shutter speed is required for different situations.
  • ISO: The light reaches the sensor after passing through aperture and shutter speed. The photographer has to decide the ISO setting. The higher the ISO number, the more the exposure. If overexposed it may deteriorate the quality of the image.

Photography tips for beginners

  • Try different composition: Composition is one of the things that you can experiment with. It helps you to take different and engaging photos. Try using different composition to make your picture look more appealing.
  • Take your time: Photography is one genre that requires your complete attention. Even the slightest mistake can cost you a good capture. Hence, it is advisable that you slow down and take your time to prepare yourself for the capture.
  • Move around: While photographing picture people generally, concentrate on the subject and the camera. However, they forget their body movement which plays an important role — moving your feet while ensuring that you get to capture your subject through different angles.

The Time When to Consider SSD Data Recovery Service

ssd (1)

It is important to remember that SSDs have a limited use cycle, measured by the amount of write actions and readings. As you use it, natural wear and tear causes loss of performance. These situations are much more evident on older drives. Current models have better performance regarding wear and tear, thanks to new technologies and support via drivers, as well as higher quality operating systems.

Whenever you find an error classified as a physical source, keep in mind that your drive is doomed, as this type of error is unrecoverable. If you encounter the issues discussed below that are recurring and have difficulty copying your files for backups, it’s time to seek expert SSD recovery service.

  1. Corrupted data

If you encounter corrupted data it is by far the most common defect in SSDs. More than a problem, you may face the appearance of corrupted data as indicating that there are flaws in the SSD structure, a situation in which you will probably have to retire it, or a signal that the file system is corrupted.

In general, corrupted data on a recent drive, which has an extended service life, may be tied from drive shortcuts to software problems such as improper computer shutdown, unsuccessful firmware upgrade, and other operating system errors.

  1. Boot issues

Blocks on the blue screen may be linked to defects with the SSD. In this type of defect, the drive has frequent problems in the boot process (boot is the system boot, from the time you turn the computer on until it becomes available for you to use it). This bug usually presents a series of errors and crashes in the boot that pass after you persist and restart several times. The problem with this error is that it can be indicative of a serious SSD fault.

  1. Trouble file system

Windows may display the message “Your computer needs to be repaired” which itself is a diagnostic of corrupted data inside your drive. Other operating systems also have similar error messages, which are displayed when the file system appears to be corrupted. This usually occurs when you lose your temper and turn off the computer without waiting for the system to finish correctly. It is time to look for a data recovery SSD service.

  1. Drive changes to read-only

This error is of the type and consists of the following: Your SSD stops accepting write, allows read-only data, as if it had turned into a locked drive for read-only.

Validating MySQL to PostgreSQL Migration



Verification of the resulting database is the most significant phase of the entire migration process. The first step of the verification procedure isidentifyingthe range of objects that must be checked. Here is list of the most important database entries that have to be migrated properly:

  1. Table structures with all necessary attributes
  2. Data
  3. Indexes and foreignkeys


There are two ways to expose table definitions inMySQL:

  • run SQL query DESC table_namein MySQL command line prompt


  • highlight the table in the left pane and click’Structure’ link in phpMyAdmin

PostgreSQL allows to browse table definitionsvia \d table_name query.

Table definition is considered as properly converted when every column in resulting PostgreSQL table has the same type, size and default value as in the original MySQLtable.

The Data

Conversion of thedata is validatedby comparison of random fragmentsof source MySQL and destination PostgreSQL tables. MySQL allows to extractfragments of data as follows:

  • run SQL query: SELECT * FROM table_name LIMIT start_record, number_of_recordsin MySQL command line prompt


  • highlight the table in the left pane and select ‘Browse’ tab in phpMyAdmin

PostgreSQL also provides SELECT-query to extract the fragment of data. It has similar syntaxwith MySQL one specified above:

SELECT * FROM table_name LIMIT number_of_records OFFSET start_record

Besides data comparison, it is also importantto check that source and destination tables have equalnumber of rows. Both MySQL and PostgreSQL allow to get number of rows using thequery:

SELECT COUNT(*) FROM table_name

The Indexes

There are two ways to get information about indexes in MySQL:

  • run SQL query SHOW INDEXES FROM table_namein MySQL console


  • highlight the corresponding table in left pane of phpMyAdmin, click ‘Structure’ link and allindexes will appear right after the table definition

PostgreSQL listsindexes at the bottom of table DDL generated through the following statement: \d table_name

The Foreign Keys

MySQL offers two options to expose information about foreign keys:

  • run SQL-query: SHOW CREATE TABLE `table name`from MySQL command prompt


  • highlight the corresponding table in left pane of phpMyAdmin,select ‘Structure’ and click the ‘Relations view’ linkbelow table definition

PostgreSQL stores information about foreign keys inthe service table “information_schema”. It can be extracted via the following query:

SELECTtc.constraint_name, tc.table_name, kcu.column_name, ccu.table_name AS fk_table_name,ccu.column_name AS fk_column_nameFROM information_schema.table_constraints AS tc    JOIN information_schema.key_column_usage AS kcu      ON tc.constraint_name = kcu.constraint_name    JOIN information_schema.constraint_column_usage AS ccu      ON ccu.constraint_name = tc.constraint_nameWHERE constraint_type = ‘FOREIGN KEY’ AND tc.table_name=’table_name’;

The Views

Theonlyway to validate conversion of viewsis to compare SELECT-statements of every view in source MySQL and destination PostgreSQL databases with respect to differences between SQL dialects of these two DBMS. Thistaskrequires extensive skills of database programming.

At the sametime, the views from source and the destination databases can be easily listed.MySQL lists all views through the following query:


PostgreSQL allows to list all views in the database using this query:

SELECT table_name FROM INFORMATION_SCHEMA.views; More articles about PostgreSQL can be found here:

Headphones will only need to send the sound waves a few millimetres so your eardrums Therefore the headphone components are much smaller and often more precise than the speaker components. Modern-day headphones can be both wired or wireless. The output is much lower when compared to the standalone speakers; the close proximity of headphones to your ears can make the volume sound very loud. You should pick out the audio interface from the best audio interfaces of 2018.

Standalone speakers:

The digital headphones will also include a digital-to-analog converter, or DAC, to produce the analogue output. The headphones function in the same way like the standalone speakers but the output is significantly different. The speakers must generate enough amplitude for the sound to be audible from a far distance. The biggest difference between loudspeakers and headphones is only the size. A loudspeaker needs to set all the air moving in a room so that you can hear the sound it is making. But the speaker in a headphone will only move the volume of air inside your ear canal.
