What's the difference between package managers?

1

Aptitude and apt-get are two of the popular tools which handle package management. Both are capable of handling all kinds of activities on packages including installation, removal, search etc. But still there are differences between both the tools which make users prefer one over the other. What are those differences that make these two tools to be considered separately is the scope of this article.

Difference Between APT and Aptitude

What is Apt

Apt or Advanced Packaging Tool is a free and open source software which gracefully handles software installation and removal. Initially it was designed for Debian’s .deb packages but it has been made compatible with RPM Package Manager.

Apt is whole command line with no GUI. Whenever invoked from command line along with specifying the name of package to be installed, it finds that package in configured list of sources specified in ‘/etc/apt/sources.list’ along with the list of dependencies for that package and...

Ubuntu 16.04 is out now, and it’s packed with exciting new changes. You have snap packages, BSD’s popular file system – ZFS – and other things. One thing you might not have heard about, as little things tend to get lost in the fray, is Apt.

What’s Apt? It’s a new package manager for Ubuntu that is poised to take over for “Apt-get.” It’s built to be more efficient, more secure, and more user friendly. So what is Canonical thinking by introducing Apt? Are there any real differences between Apt and Apt-get? Let’s find out!

Apt was introduced in 16.04 to simplify the package manager and to merge multiple commands into one single command. The functions from “apt-get” have been taken and have been created to function in similar ways in Apt.

Despite the fact that these new Apt commands are created to function similar to the old Apt-get commands, these new commands are not calling the old ones. They’re completely new – fresh commands to interact with...

Work Package and Activity – Definitions, Differences & Examples

You are at the right place if you want to know the difference between Work Package and Activity. But, why do you want to differentiate between Work Package and Activity?

Practically, it doesn’t matter whether you call a Work Package an Activity or vice-versa. At the end of the day, you have to complete the project. The project work will not change because of nomenclature. However, if you are preparing for the PMP Exam then it is important to differentiate between Work Package vs Activity.

It is important to understand the definition of Work Breakdown Structure (WBS) in its purest form to understand the difference between Work Package and Activity. You should read my article 7 Reasons to Create WBS before venturing ahead. Succinctly, we can say that:

A WBS is deliverable oriented. A deliverable is an outcome or a result of something. A deliverable provides some value to the project...

Chromium is the open-source project that forms the basis for Google Chrome. Because it’s completely open source, Chromium is available in many Linux distributions’ software repositories for easier installation.

The Chromium web browser is also available for other platforms. You could run it on Windows or Mac — in theory. Similarly, “Chromium OS” is the name of the open-source project that forms the basis of Google’s Chrome OS.

Getting Chromium or Chrome

On Linux, Chromium can often be installed directly from your Linux distribution’s software repositories. On Ubuntu Linux, for example, it can be installed by opening the Ubuntu Software Center, searching for Chromium, and clicking Install. It will be updated with security updates from your Linux distribution’s software repositories.

On Windows and Mac, actually using Chromium is tougher. Official Chromium builds are available, but they’re bleeding-edge-only and won’t automatically update. The...

Today I was sort of idly thinking about the difference between a manager and a team leader. I suppose these terms mean different things in different organizations, but I think it makes sense to propose general definitions that clarify a somewhat hazy topic. We’ll assume that in both cases, the members of the team report to the manager or team leader, at least for the duration of the project that they’re working on. (If you work at a place where people have a manager and a team leader and the responsibilities are divided, all bets are off.)

Both are accountable for the overall performance of the team. If the team fails to meet its goals or is dysfunctional, that’s on the person who’s running the team, regardless of their title. I strongly prefer to think about these responsibilities in terms of accountability rather than authority for the reasons I talked about in my post about judgement and influence. I think that teams function most effectively when the members buy into the...

Kali Linux is the next-generation edition of BackTrack. It is BackTrack reborn. If you’ve been using BackTrack, or you’re are thinking about using BackTrack, forget it. Kali Linux is what you want to be using. What’s the difference?

BackTrack is based on an old edition of Ubuntu, while Kali is based on the latest edition of Debian. On the installation side, Kali Linux uses Debian’s graphical installer, which means you get features like LVM, the Linux Logical Volume Manager, and disk encryption. With BackTrack and its Ubuntu installer, you get none of that.

Those are a few of the major differences. When it comes to installing applications or software on Kali Linux, there is no difference between it and BackTrack. This article shows the many methods you can use to install and manage applications on Kali Linux 1.0. Obviously, this is not intended for experienced users, but for those new to Linux.

1. From the command-line: Since Kali is based on Debian, installing...

One of the most common questions from our users is: “What is the difference between the three SolidWorks packages (Standard, Professional, Premium)?” The answer really depends on many factors…


One of the most common questions from our users is “What is the difference between the three SolidWorks packages (Standard, Professional, Premium)?” This is often followed by “When does it make sense to upgrade from Standard to Professional or Premium?” The answer really depends on many factors, and we have a complex matrix to outline every feature in each package, but the matrix is…well…complicated, so I wanted to share a brief description of the three packages, as well as two easy ways to figure out which is best for you.

Ask yourself:

What main functionality differences do I need? Will upgrading to SolidWorks Professional or Premium streamline my design process?

These two questions may be best answered in a video (below), but I wanted to take a stab at...

The Supervisory and Managerial category describes positions that exercise independent judgment in determining the distribution of work of at least 2 FTEs, and make decisions or recommendations about 3 or more of the following: hiring decisions, performance ratings, merit increases, promotional opportunities, reclassification requests, written warnings, suspensions, disciplinary actions, and/or resolution of grievances or complaints. Each individual job description is reviewed against this definition, and if the customized job content provided by the manager for custom scope, key responsibilities, problem solving and supervision (including organizational chart) does not support the definition of a supervisor or manager job standard, the position will subsequently be approved for a professional job title. Professionals may achieve and be responsible for many of the same functional responsibilities as a manager or supervisor, but achieve results through their own, personally-performed...

Probably the most popular package managers are apt-get, aptitude, synaptic, and Software Center. There are others (Linux Mint has its own, and there are some designed for KDE), but these are the ones you'll run into most often.

apt-get is a simple command-line tool. It's handy if you know the exact package name of what you want to install and don't want to spend time clicking through a GUI to get it.

aptitude is very similar to apt-get, and I've heard that it deals better with crazy dependency situations. Which one is really better is debatable.

synaptic is a low-level GUI. This is a good choice if you are a fairly advanced user but are not comfortable with command-line utilities.

Software Center is a very high-level, new-user-friendly GUI. Software is nicely categorized so that, if you're not exactly sure what app you want, you can find what you need quickly. The Software Center also stands out in that it is the only package manager in this list that...

Specific differences are described by the generic scope of each supervisory and managerial level. Another way to look at it is that a manager is responsible for making significant decisions on what the unit does: its purpose, functions and role, and for making commitments and decisions that require the expenditure of significant unit resources. Managers have a significant, external focus (to the world outside the unit), whereas a supervisor has a more internal focused responsibility for implementing the manager’s decisions through the work of subordinate employees. Once a decision is made on what to do, supervisors have a significant role in deciding how to do it; how to achieve the objective established by the manager. Supervisors often perform the same kind of work that the subordinates do; managers do not do the daily work of the unit as a regular part of their work, they may do it more on an exception basis or in resolving the most difficult problems facing the...

These two buzzwords cause confusion among business professionals as they are used synonymously. From the first look one might have an impression that “dashboard” and “scorecard” are interchangeable, but there are some important distinctions that I’d like to analyze in this article.

I’m presenting the results of the comparative analysis in the form of a table. I compare “dashboard” and “scorecard.” As long as the most used form of the “scorecard” today is a Balanced Scorecard, in my analysis I’ll focus on this very framework.

The differences between a Dashboard and a Balanced Scorecard

Contrast the process of design

The Balanced Scorecard design process is up to down (with some exceptions). It starts with global business objectives and then moves down to KPIs level. The dashboard is more oriented on an operational level; as a result the process starts with the identification of relevant metrics and monitoring of their values. If something...

I think the previous posters have covered well some of the basic distinctions. (npm's use of nested dependencies is hugely helpful in managing large, complex applications.)

I'm surprised, however, that nobody has explicitly explained one of the most fundamental distinctions between Bower and npm. If you read the answers above, you'll see the word 'modules' used often in the context of npm. But it's mentioned casually, as if it might even just be a syntax difference.

But this distinction of modules vs. globals (or modules vs. 'scripts') is possibly the most important difference between Bower and npm. The npm approach of putting everything in modules requires you to change the way you write Javascript for the browser, almost certainly for the better.

The Bower Approach: Global Resources, Like Tags

At root, Bower is about loading plain-old script files. Whatever those script files contain, Bower will load them. Which basically means that Bower is just...

You’ve just deployed an ecommerce site for your small business or developed the next hot iPhone MMORGP. Now what?

Don’t get hacked!

An often overlooked, but very important process in the development of any Internet-facing service is testing it for vulnerabilities, knowing if those vulnerabilities are actually exploitable in your particular environment and, lastly, knowing what the risks of those vulnerabilities are to your firm or product launch. These three different processes are known as a vulnerability assessment, penetration test and a risk analysis. Knowing the difference is critical when hiring an outside firm to test the security of your infrastructure or a particular component of your network.

Let’s examine the differences in depth and see how they complement each other.

Vulnerability assessment

Vulnerability assessments are most often confused with penetration tests and often used interchangeably, but they are worlds...

Red Hat Enterprise Linux is not free, and its also used for business.Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system. Red Hat Linux 1.0 was released on November 3, 1994. It was originally called “Red Hat Commercial Linux” It is the first Linux distribution to use the packaging system, the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.

Red Hat’s Features:

Red Hat Linux introduced a graphical installer called Anaconda, intended to be easy to use for novices, and which has since been
adopted by some other Linux distributions. It also introduced a built-in tool called Lokkit for configuring the firewall capabilities. It uses .rpm package called Red Hat Package Manager.

RPM Package Manager (RPM) is a powerful command line driven package management system capable of installing, uninstalling,...

Ubuntu provides four different software repositories, all of them official — Main, Restricted, Universe, and Multiverse. Main and Restricted are fully supported by Canonical, while Universe and Multiverse don’t receive the support you might expect.

On older versions of Ubuntu, only the Main and Restricted repositories were enabled by default. Ubuntu desktop systems now come with all four repositories enabled by default.

Main – Officially Supported, Open-Source Software

Main is described as “Canonical-supported free and open-source software.” Canonical is Ubuntu’s parent company, and they provide official support for all the software packages in Main. Every open-source software package included in Ubuntu’s default installation is included here. Other important packages — server software, for example — are also part of Main.

Canonical supports packages in the Main repository with security updates and other critical fixes for the lifetime of the...

Many people might consider a program to be just one really large project. A project is a singular effort of defined duration, whereas a program is comprised of a collection of projects. Problem solved, right?

Actually, it’s a bit more complex than that. While programs and projects actually have several different characteristics and different functions within an organization, they also have many commonalities. Likewise project managers and program manager are two different roles within an organization, as well, yet they share similar duties.

While the state of the industry is always changing, it behooves you and your organization to know when your projects should become programs. Let’s look at how they’re different – and how they’re the same – so you can apply the concepts to your own programs and projects.

Projects and Programs: How They’re Different
