Frequently asked questions Does uMobix cell phone tracker work in real-time?Yes, uMobix tracking app logs everything users do and sends reports directly to your user account. It usually takes up to 5 minutes to synchronize all data from a monitored device. In case of iOS, data synchronization depends on the backup perfomance (in some cases can take up to 24 hours).
How does uMobix work?Our tracking app monitors and obtains information from target devices in stealth mode. All recorded data is sent to your userspace where it appears in the form of comprehensive dashboards. To start using mobile tracker, you have to purchase the app, log in to your account, install uMobix on an Android device, or provide iCloud credentials of a target iOS device.
Is it legal to use cell phone tracker?It is absolutely legal to use uMobix if:
– You own the device you’re going to monitor;
– You’ve informed the designated users that their activities are being watched.
How often will it update from the target device?By default, data is updated each 5 minutes for Android devices. You can adjust intervals depending on cell phone settings and internet connection. In case of iOS, data synchronization depends solely on the backup perfomance (in some cases can take up to 24 hours).
How can I track the location of a cell phone?With the help of our cell phone tracker, you can locate a phone on the map. The technology also allows seeing where a user has been by using the location history feature. All information is displayed on the interactive map. You only have to log in to your account and open the needed page.
Can I track a cell phone with just a number? Can you track someone’s location through their phone?Yes, you can access a person’s phone location by using a cell phone tracker. You have to install the tracking app on a target device to be able to see user location in real-time.
How many devices can I track?One subscription gives you access to one device. You can unlink and link as many devices as you wish but only one at a time.
Where can I view data from target device?All data is delivered to your personal account. You can access your dashboard from any device or computer with your login credentials.
Is the icon visible?After installation on an Android device, you can remove the icon from the menu. We know that tech-savvy kids can spot the icon right away. For iOS devices, the installation process does not include downloading the app on the device, so there won’t be any icon in the menu.

Advanced Sql For Data Science
This article was published as a part of the Data Science Blogathon.
The article focuses on techniques to deal with a wide range of data types; mastering these can be useful for the user. The article doesn’t focus on the basics of SQL, including standard syntax, functions, and applications but aims to expand the fundamental knowledge of SQL. The writing also covers the concept of subqueries.
Let’s get started!
S sSQL provides built-in functions for performing operations, categorized into two types. The types are:
1. Aggregate FunctionsThese functions are used to perform operations on values of the column, and a single value is returned. The SQL provides the following aggregate functions:
AVG(): It returns the calculated average value from values of the selected numeric column
Syntax of AVG() function:
Select AVG(column_name) From table_name;Example of AVG() function:
Select AVG(Salary) AS AverageSalary From Employees;COUNT(): This function is used to count the number of rows returned in a Select Statement.
Syntax of COUNT() function:
Select COUNT(column_name) From table_name;Example of COUNT() function:
Select COUNT(*) AS NumEmployees From Employees;FIRST(): The function returns the first value of the selected column.
Syntax of FIRST() function:
Select FIRST(column_name) From table_name;Example of FIRST() function:
Select FIRST(Employee_ID) AS FirstEmployee From Employees;LAST(): The function returns the last value of the selected column.
Syntax of LAST() function:
Select LAST(column_name) From table_name;Example of LAST() function:
Select LAST(Employee_ID) AS LastEmployee From Employees;MAX(): The function returns the maximum value of the selected column.
Syntax of MAX() function:
Select MAX(column_name) From table_name;Example of MAX() function:
Select MAX(Salary) AS MaxSalary From Employees;MIN(): The function returns the minimum value of the selected column.
Syntax of MIN() function:
Select MIN(column_name) From table_name;Example of MIN() function:
Select MIN(Salary) AS MinSalary From Employees;SUM(): The function returns the sum of the values of the selected column.
Syntax of SUM() function:
Select SUM(column_name) From table_name;Example of SUM() function:
Select SUM(Salary) AS TotalSalary From Employees; 2. Scalar FunctionsThe scalar functions are based on user input and return a single value. Let’s understand through scalar functions:
UCASE(): The function converts the value of a field to uppercase.
Syntax of UCASE() function:
Select UCASE(column_name) From table_name;Example of UCASE() function:
Select UCASE(Ename) From Employees;LCASE(): The function converts the value of a field to lowercase.
Syntax of LCASE() function:
Select LCASE(column_name) From table_name;Example of LCASE() function:
Select LCASE(Ename) From Employees;MID(): The function extracts texts from the text field.
Syntax of MID() function:
Select MID(column_name,start,length) FROM table_name;Specifying the length is not compulsory here and the start represents the start position.
Example of MID() function:
Select MID(Ename, 1, 4) From Employees;LEN(): The function returns the length of the specified value.
Syntax of LEN() function:
Select LENGTH(column_name) From table_name;Example of LEN() function:
Select LENGTH(Ename) From Employees;ROUND(): The function returns the round numeric value to the specified decimal places. This arithmetic operation is performed considering IEEE 754 standard.
Syntax of ROUND() function:
Select ROUND(column_name, decimals) From table_name;decimals in the syntax specify the number of decimals to be fetched.
Example of ROUND() function:
Select ROUND(Salary, 0) From Employees;NOW(): The function returns the current date and time of the system.
Syntax of NOW() function:
Select NOW() From table_name;Example of NOW() function:
Select Ename, NOW() From Employees;FORMAT(): The function formats how a field is to be presented.
Syntax of FORMAT() function:
Select FORMAT(column_name, format) From table_name;Example of FORMAT() function:
Select Ename, FORMAT(NOW(), 'YYYY-MM-DD') AS Date From Employees;CONCAT(): The function joins the values stored in different columns, or it can be used to join two strings simply.
Syntax of CONCAT() function:
Select CONCAT(string_1, string_2,...., string_n) AS Alias_Name; Select CONCAT(column_name1, column_name2,...., column_name_n) From table_name;Example of CONCAT() function:
Select CONCAT('Hello', ' Everyone') As Gesture; Select CONCAT(FirstName, LastName) AS EmployeeName From Employee;REPLACE(): The function replaces the occurrence of a specified value with the new one.
Syntax of REPLACE() function:
Select REPLACE(Original_Value, Value_to_Replace, New_Value) AS Alias_Name; Select REPLACE(Column_Name, Character/string_to_replace, new_String/character ) AS Alias_Name FROM Table_Name;Example of REPLACE() function:
Select REPLACE('APPSE', 'S', 'L'); Select LastName, REPLACE(LastName, 'r', 'a') AS Replace_r_a From Employees;POSITION(): The function returns the position of the first occurrence of a specified substring in a string.
Syntax of POSITION() function:
Select POSITION(substring IN string/column_name);Example of POSITION() function:
Select POSITION("A" IN "APPLE") As Position; Select POSITION("a" in FirstName) From employees; SQL JoinsAs the name suggests, JOIN means combining something, which refers to combining two or more tables. The JOIN combines the data of two or more tables in a database. The joins are used if we want to access the data of multiple tables simultaneously. The joining of tables is done based on a common field between them.
According to ANSI standards, there are five types of JOIN:
INNER Join
LEFT OUTER Join
RIGHT OUTER Join
FULL OUTER Join
CROSS Join
Firstly, let’s look at how SQL JOIN works:
Suppose we have two tables:
1. Parent Table
ID Name Age Address Salary
1 Ram 26 Mumbai 20000
2 Jack 28 Delhi 18000
3 John 25 Pune 25000
4 Amy 32 Delhi 22000
2. Student Table
Student_Id Class Class_ID Grades
101 9 1 A
102 8 3 B
103 10 4 A
So, if we use the following JOIN statement:
Select ID, Name, Student_ID, Grades From Parent p, Student s Where chúng tôi = s.Class_ID;The result would be:
ID Name Student_ID Grades
3 John 102 B
1 Ram 101 A
4 Amy 103 A
1 Ram 101 A
Now, let’s look at different types of joins:
1. SQL OUTER JOINIn the outer JOIN of SQL, the content of the specified tables is integrated whether their data matches or not.
Outer join is done in two ways:
Left outer join, or a left join, returns all the rows from the left table, combining them with the matching rows of the right table. If there is no matching data, it returns NULL values.
Right outer join, or a right join, returns all the rows from the right table, combining them with the matching rows of the left table. If there is no matching data, it returns NULL values.
Syntax of LEFT JOIN:
Select table1.column1, table2.column2,.... From table1 LEFT JOIN table2 ON table1.coulmn_field = table2.column_field;Example of LEFT JOIN:
Select ID, Name, Student_Id, Grades From Parent LEFT JOIN Student ON chúng tôi = Student.Class_ID;Syntax of RIGHT JOIN:
Select table1.column1, table2.column2,.... From table1 RIGHT JOIN table2 ON table1.coulmn_field = table2.column_field;Example of RIGHT JOIN:
Select ID, Name, Student_Id, Grades From Parent RIGHT JOIN Student ON chúng tôi = Student.Class_ID; 2. SQL FULL JOINThe full join or full outer join of SQL returns the combination of both right and left outer join, and the resulting table has all the records from both tables. If no matches are found, then the NULL value is returned.
Syntax of FULL OUTER JOIN:
Select * From table1 FULL OUTER JOIN table2 ON table1.column_name = table2.column_name;Example of FULL OUTER JOIN:
Select * From Parent FULL OUTER JOIN Student ON chúng tôi = Student.Class_ID; 3. SQL CROSS JOINThe SQL cross join used to combine the data gives the cartesian product of the sets of rows from the joined table. When each row of the first table is combined with every single row of the second table, it is called Cartesian join or Cross join.
The resulting number of rows equals the product of the number of rows in the first table to the number of rows in the second table.
Syntax of CROSS JOIN:
Select table1.column1, table2.column2,.... From table1 CROSS JOIN table2 ON table1.coulmn_field = table2.column_field;Example of CROSS JOIN:
Select * From Parent CROSS JOIN Student ON chúng tôi = Student.Class_ID; Grouping DataIn SQL, the GROUP BY statement is used for organizing data into groups based on similarity in the data. Further data is organized with the help of the equivalent functions. In simple words, if different rows of a specified column have the same values, they are placed together in a group. The following criteria are taken into consideration while using Group By statement:
In SQL, the Select statement is used with the GROUP BY clause.
Where clause is used before GROUP BY clause.
ORDER BY clause is placed after this clause.
Syntax of GROUP BY clause:
Select column1, function_name(column2) From table_name Where condition GROUP BY column1, column2 ORDER BY column1, column2;Example of GROUP BY clause:
Select Name, SUM(Salary), Age From Employee GROUP BY Age;One important point to remember here is that the Where clause is used for deciding purposes. It is used to place conditions on columns to decide the part of the result table. Here, we cannot use aggregate functions like COUNT(), SUM(), etc. with the Where clause. So, we use the Having clause.
Syntax of Having Clause:
Select column1, function_name(column2) From table_name Where condition GROUP BY column1, column2 Having condition ORDER BY column1, column2;Example of Having Clause:
Select Name, SUM(Salary), ID From Employee GROUP BY Name ORDER BY ID;The Select statement can use constants, aggregate functions, expressions, and column names in the GROUP BY clause.
SQL CASEThe CASE statement operates like if-then-else logical queries. When the specified condition is true, the statement returns the specified value. If the condition turns out to be false, it executes the ELSE part. When there is no specified ELSE condition, it returns a NULL value.
The CASE statement is used in Select, Delete, and Insert statements with Where, ORDER BY, and GROUP BY clauses.
Syntax of CASE statement:
CASE WHEN condition_1 THEN statement_1 WHEN condition_2 THEN statement_2 . . . WHEN condition_N THEN statement_N ELSE result END;The above query will go through each condition one by one. If the expression matches the query, it will print the result accordingly and skip all the condition statements afterward. If no condition matches the term, the control would go to the ELSE part and return its result. Here, the ELSE part is optional; in that case, it returns a NULL value if no condition satisfies the expression.
Example of CASE Statement:
Select Student_ID, Name, Subject, Marks, CASE ELSE 'FAIL' END AS Student_Result From Student; SQL ViewTo hide the complexity of the data and prevent unnecessary access to the database, SQL introduces the concept of VIEW. It allows the user to pick a particular column rather than the complete table. The view or virtual table as it is considered depends on the result-set of the predefined SQL query.
In the views, the rows don’t have any physical existence in the database, and just like SQL tables, views store data in rows and columns using the Where clause.
Syntax to create View from Single Table
Create VIEW View_name AS Select column_name1, column_name2,....., column_nameN From table_name Where condition;Syntax to create View from Multiple Tables
Create VIEW View_name AS Select table_name1.column_name1, table_name2.column_name1,..... From table_name1, table_name2,....., table_nameN Where condition;We can also modify the current view and insert new data, but it can only be done if the following conditions are followed:
Views based on one table can only be updated, not the one formed from multiple tables.
The view fields should not contain any NULL values.
The view doesn’t contain any subquery and DISTINCT keyword in its definition.
The view cannot be modified if the Select statement used to create a view contains JOIN, HAVING, or GROUP BY clause.
The view cannot be updated if any field contains an aggregate function.
Syntax to Update a View:
CREATE OR REPLACE VIEW View_name AS Select column_name1, column_name2,...., column_nameN From table_name Where condition;To delete the current view from the database DROP statement is used:
DROP VIEW View_name; SQL UNION, UNION ALL, and EXCEPTThe UNION operator combines the result of two or more Select queries and results in a single output.
Syntax of UNION operator:
Select column_name1, column_name2,...., column_nameN From table_name1 UNION Select column_name1, column_name2,...., column_nameN From table_name2 UNION Select column_name1, column_name2,...., column_nameN From table_name3;The UNION ALL operator has the same functionality as the UNION operator, the only difference is that UNION ALL operator shows the common rows in the result, whereas the UNION operator does not.
Syntax of UNION ALL operator:
Select column_name1, column_name2,...., column_nameN From table_name1 UNION ALL Select column_name1, column_name2,...., column_nameN From table_name2;The EXCEPT operator is used to filter out data. The statement combines the two select statements and returns the records that are present in the first Select query and not in the second Select query. It works in the same way as the minus operator does in mathematics.
Syntax of EXCEPT operator:
Select column_name1, column_name2,...., column_nameN From table_name1 EXCEPT Select column_name1, column_name2,...., column_nameN From table_name2; SQL SubqueriesSyntax to write an inner query:
Select column_name1, column_name2, ...., column_nameN From table_name Where operator (Select column_name1, ..., column_nameN From table_name);The subquery is executed before the outer or main query, and the main query uses its result.
There are some conditions required to be followed for writing a subquery:
Subqueries are enclosed within parentheses.
A subquery has only one column in the SELECT clause unless there are multiple columns in the main query for comparing the selected columns of the subquery.
The subquery cannot contain an ORDER BY command, but the GROUP BY clause can be used to perform the same function, the main query can use an ORDER BY clause.
Subqueries that return multiple rows can only be used with multiple value operators like IN operator.
The BETWEEN operator cannot be used with a subquery but within it.
Example of a subquery:
Select * From Employees Where ID IN(Select ID From Employees_AnotherThe above statement selects the data of employees in the Employees table whose given salary is more than 4500 in the Employees_Another table.
Update Employees SET Salary = Salary * 0.25 Where Age IN(Select Age From Employees_AnotherThe above query updates the employees’ salary value in the Employees table if their age is greater than or equal to 27 in the Employees_Another table.
In a nutshell, we learned about:
How can aggregated functions be used to get the required data, and how can we compute various functions
Creating and working on virtual tables
Some additional clauses like CASE, UNION, UNION ALL, and EXCEPT
The concept and working of SQL subqueries
SQL is all about constant practicing. Keep on practicing, and you will master it in no time!

3 Different Approaches To Secrets Management For Modern Enterprises
Given the increasing adoption of CI/CD methodologies and container orchestration approaches, today’s enterprises face several challenges associated with cloud infrastructure sprawl.
For processes to run smoothly, CISOs and DevOps engineers need to ensure that machine identities can be verified on the fly, while credentials like keys, certificates and passwords are secure, with access privileges granted only as needed.
Indeed, safeguarding secrets has become more complex than ever.
Let’s unpack the issues at hand by taking a closer look at three approaches to enterprise secrets management. Note that the best approach for your organization depends on its unique circumstances and the nature of your infrastructure.
1. Open source vaultsOpen source secrets vaults like the one offered by HashiCorp are generally seen as the industry’s go-to solution. HashiCorp Vault integrates with your existing infrastructure, and when configured properly across cloud environments, it’s extremely useful as a centralized dashboard for managing your secrets. It can also scale as your enterprise grows, connecting and centralizing secrets from multi-cloud environments.
Linking infrastructure is, obviously, only one part of the picture. A robust security tool must back this up with the right functionalities. Solutions such as HashiCorp Vault incorporate zero trust or ZT security principles. At its core, ZT requires every entity to validate its identity before accessing information. This principle limits unauthorized usage and protects data from expired credentials, a critical issue in the enterprise.
Open source vaults help you design and monitor time-based access to secrets, a critical functionality given the machine-dominated environment at most enterprises. Modern infrastructure is dominated by microservices and containers, all operating in a fast-paced DevOps environment.
First, open source vaults are time-consuming and complex to deploy and maintain. Upgrading to Hashicorp Vault’s enterprise version is an option, but it can get extremely expensive. While the final cost depends on the degree of support an organization needs, costs frequently run higher than five figures per cluster. Add management complexity, and an open source vault might not suit smaller teams on a tight budget.
However, if you have the resources, they’re a great way to secure secrets and upgrade to market best practices.
2. SaaS solutionsIn response to the shortcomings of open source vaults, providers such as Akeyless offer subscription-based solutions for secrets management. These platforms work via a SaaS model, so they can offer secrets management tools across increasingly sprawling cloud environments, with limited friction when it comes to configuration and deployment.
Akeyless’s SaaS vault operates in similar ways to its open source cousins – with a few critical differences. First, you do not have to spend resources installing and maintaining it across your infrastructure, saving time and money. Akeyless offers multi-tenancy, availability, and out-of-the-box backup as standard.
SaaS vaults also support both static and dynamic secrets storage and retrieval. While HashiCorp’s solution is an exception, most open source vaults offer just static secrets, putting them at odds with the current state of cybersecurity. SaaS vaults go above and beyond in this regard, also supporting credential rotation, automatic renewal, and remote access management.
Akeyless integrates with dozens of other platforms, such as container orchestration solutions, browser extensions, and API-based runtime secret injection into code. The platform offers plenty of tools for identity and access management (IAM) as well, including just-in-time (JIT) credential generation.
And with its encryption model, which stores encrypted segments of each secret across several cloud servers, Akeyless eliminates the “secret zero” problem – a situation referring to one primary secret that guards all other secrets, which is problematic because once a hacker gets through the main gate, they can access the entire trove freely. Akeyless negates this critical flaw by storing all keys in encrypted fragments, distributed across its own cloud infrastructure, with some segments remaining on-prem on the user’s side.
Add intuitive UI, full support, and cost-effectiveness to this mix, and SaaS vaults are perhaps the most accessible option for most enterprises. While they might not suit some companies with heavy customization demands, a SaaS secret management tool is often the best choice.
3. Cloud service provider vaultsCloud service providers (CSPs) like Azure, Google Cloud and AWS offer secret vaults and managers out-of-the-box. These tools adhere to best practices and offer much of the same functionality you will find in the previous approaches. However, there are two key differences. Firstly, you do not have the same level of control over your secrets when using a CSP’s solution, and there are fewer integrations with coding and DevOps platforms. And secondly, because they’re cloud vendor-specific, they can’t be used for multicloud infrastructure.
When setting up your CSP vault, you must share your master keys with the CSP to enable full integration, leaving yourself vulnerable to the CSP’s security protocols. In case of a breach, your secrets are at risk for no fault of yours. In some cases, government entities may seize your data, since CSPs are obligated to hand them over to the authorities.
In contrast, SaaS vaults support cryptographic key generation that safeguards your master keys even from them. In short, no one has access to your complete keys except you.
These shortcomings make CSPs a poor option for most enterprises. However, they’re easy to set up and get up and running. If this convenience is the most important aspect of your secrets management program, CSP vaults are the right choice for you.
Tried-and-tested approachesThe approaches highlighted in this article offer both positives and negatives for most enterprises. The right choice depends on the unique set of circumstances your company is experiencing. Whatever your choice, there is no doubt that secrets management solutions are critical to combating infrastructure sprawl that afflicts most organizations.
7 Advanced Link Building Strategies For A Competitive Edge
We all know it’s not worth our time to build sub-par links anymore. It’s time to get innovative with our link building tactics. We previously shared a few lesser-known link building techniques and post panda/penguin era link acquisition strategies here, but we are of the opinion that you can’t have too many.
So, here are a few more techniques that will help you push the envelope and approach link building with the mindset of a serious marketer:
1. Coin a Phrase and Set Up AlertsThe idea behind this strategy is to invent a new buzzword, try and get it to catch on, and then capture links as a result. Since not everybody who uses the phrase is going to send a link your way, you can set up Google Alerts to capture mentions of the phrase. If it’s clear front context that they’re talking about the buzzword you coined, this can be a great opportunity to build a link.
Now, if your site doesn’t quite have the exposure to get a buzzword out there, this might seem like a pointless exercise in futility. However, all it takes is $50 to get your article in front of 1,000 people on StumbleUpon.
If your campaign is targeted toward the right people, and the phrase is catchy enough, this could well be enough to start getting the phrase in use by many in the online community.
2. Produce a Resource and Set Up AlertsSimilarly, you can put together a video, white paper, or infographic, set up Google Alerts on the topic, and start contacting people. Any time a question about the topic comes up online, this is an opportunity to answer their question with a link to your resource. This is a great option because the answer is completely on-topic.
3. Update Somebody Else’s ContentYou know those pieces of content that seem to just keep on giving? This is the content that you want to keep investing in with updates, corrections, etc. to keep it relevant. It’s common practice to revisit your best content, keep promoting it, and keep improving it.
But fixing up your old content can be also be a chore, and that’s where you come in. Instead of submitting a guest post, why not contact a blogger with an interesting fact or update that will help keep one of their top posts fresh and interesting?
Try doing a search for some of the more broad terms related to your keywords, and visiting some of the blog posts you come across. Focus on the ones that already seem to have massive appeal. Read through, and catch yourself if you start thinking this reminds me of…
As soon as that happens, get in touch and let them in a surprising piece of information that’s relevant to the article. This can be a great opportunity to earn a link.
4. Customize a WidgetYou might not be a coding master with the ability to put together a master widget that everybody’s going to want to download. However, odds are pretty good you have the coding or design skills necessary to customize a widget so that it fits a site’s branding and appearance.
Try seeking out blogs in your niche, or peripheral niches, that use widgets you recognize. Give the widget a tweak so that it fits the site better, place a link, and offer the new take on the widget to the blogger. This is especially powerful for popular blogging topics that aren’t centered around the tech industry.
That said, be ethical, and make sure the blogger is aware of the link back to your site. There’s no reason to hide this. As long as you understand how to work with people amicably it shouldn’t be a problem.
5. Buy Display Ads 6. Work with ExpertsThere’s no reason to produce content in a vacuum. In fact, most of the best content is the result of collaboration. Involve experts in the creation, fact-checking, and refinement of your content before it goes live. The more experts you work with, the more opportunities you have for additional links.
Don’t try to scale this too much. The more people you try to involve, the less commitment you can get from each of them, especially if you are automating your outreach. Instead, customize your outreach emails and be clear about why you are contacting them. Don’t ask for too much from them, and make it clear that they will be getting something out of the exchange as well.
7. Get In Business DirectoriesMost “link” directories are useless (though exceptions like DMOZ and AllTop are worth your time). However, getting added to relevant business directories is certainly a worthwhile effort, since these links are from reputable organizations and are a good sign of trust. These kinds of links can come from:
The Better Business Bureau
The Chamber of Commerce
Your local library
Other relevant city and state government resources
Accrediting organizations
Business memberships
Focus on links from reputable business lists that people actually use and care about. Avoid directories that exist simply to provide links for search engine authority, since these are the least likely to offer any real search engine authority.
Can you think of additional alternatives? If you can, pass them along, and if you liked this, be sure to pass it along as well.
