When implemented effectively, Continuous Delivery (CD) embraces the DevOps philosophy of collaboration between traditionally separate teams: development and operations. CD is the automated implementation of the build, deploy, test, and release process. With CD, software is always in a releasable state. With every change to any part of the software system — infrastructure, application code, configuration, or data — a release candidate goes through a delivery pipeline where the software is created, environments are built, databases are constructed, tests are run, and software is deployed. Many tools make up a platform capable of moving the software system along this pipeline.

Snort is a free and open source network intrusion prevention system (NIPS) and network intrusion detection system (NIDS)
Snort's open source network-based intrusion detection system (NIDS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching. These basic services have many purposes including application-aware triggered quality of service, to de-prioritize bulk traffic when latency-sensitive applications are in use.
The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, common gateway interface, buffer overflows, server message block probes, and stealth port scans.
Snort can be configured in three main modes: sniffer, packet logger, and network intrusion detection. In sniffer mode, the program will read network packets and display them on the console. In packet logger mode, the program will log packets to the disk. In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. The program will then perform a specific action based on what has been identified.
Please contact us to learn how SNORT can help your network Management and security solutions.

If your organization uses multiple spreadsheets across organization for information storage and reporting, you need to consider a database for efficiency and productivity.
Microsoft Access is a database management system (DBMS) from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately.
Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.
Software developers, data architects and power users can use Microsoft Access to develop application software. Like other Microsoft Office applications, Access is supported by Visual Basic for Applications (VBA), an object-based programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating system operations.

Definition of Information Technology Service Management
IT service management (ITSM) refers to the entirety of activities – directed by policies, organized and structured in processes and supporting procedures – that are performed by an organization to plan, design, deliver, operate and control information technology (IT) services offered to customers. It is thus concerned with the implementation of IT services that meet customers' needs, and it is performed by the IT service provider through an appropriate mix of people, process and information technology.
Differing from more technology-oriented IT management approaches like network management and IT systems management, IT service management is characterized by adopting a process approach towards management, focusing on customer needs and IT services for customers rather than IT systems, and stressing continual improvement.
The IT Chaos and Solutions Process
Now a days, the future of a company appears to hang almost entirely on Enterprise e-commerce and mission critical ERP. The political storm brewing behind such projects, led by the marketing manager and hidden agenda, adds further tension. Faced with the conflict of E-commerce and ERP requirements against firefighting and competing projects, IT manager and his team enter a spiral of problems, mistakes, gloom and despair. Thanks to a growing insight into Lean, Agile and DevOps concepts, IT manager and his team can gradually evolve their way of working. By the time NextKillerProject arrives later in the scenario, they’re able to release and support the project reliably, efficiently, and emerge with strengthening morale out the other side. Value of central change management and Information Technology Service Management (ITSM) is proved and demonstrated to know-all skeptics. No more hardware upgrades causing software firefighting and vice versa.
A Keen Computer Observation
The problem addressed by ITSM has appeared in almost all the organization that has formal and informal IT department. The problem the ITSM addresses is not only technical like network management or software development- it encourages a culture of system level thinking and teamwork. The central change management, testing and experimentation, rollout and rollback scenario consideration is crucial for success.
ITSM stresses the fact that Systems Engineering is necessary for avoiding core IT chaos involving Software, Hardware and IT fire-fighting and finger pointing with individual inner agenda and organizational politics . It’s not the case that, DevOps and Agile approaches to working have magically evaporated all the challenges facing a normal organization. Conflict, incidents and mistakes are inevitable – what counts is how team members grow to manage and resolve them using Systems Engineering principals . In the end the organization must have structure, process, and a more open attitude to change and adaptation to stand them in good stead. An approach to System Level thinking and systems approach is necessary
At its most practical, The ITSM is an illustrative series of process and suggestions for ways to evolve IT from a function that’s viewed as a bottleneck to one that’s widely agreed to be an indispensable capability. And at both levels, The enterprise ERP and E-commerce needs DevOps that includes the wider organization, and the wider organization can learn a lot from DevOps and ITSM.

A little while ago I wrote a very loose account of my experiments to evaluate my own use of Solid State replacements for spinning hard drives. The result was I acquired two devices and now have them in use. This is about the final installation and actual use for the first sixty days. I hope this will encourage others to try similar upgrades.
In another article I have expounded my relatively easy transition to an all laptop “portable” network. IT has changed position in my life and become more hobby than calling. I am retired so I work more with cameras than computers. I now live in an apartment rather than a home of my own. The need for easier dismantle and setup of the network became an issue and I successfully (my viewpoint) made the transition.
There is one disadvantage to being all laptop, it can become very expensive to have the fastest equipment. In my somewhat constrained retirement I must watch that I do not overspend! So I tend to buy equipment from the most economically priced sources. I cannot afford much brand loyalty. My choices are therefore not based on such preferences, unless I can get my preferred choice on sale. That process is what controlled my SSHD experiments in 2016.
Installing the SSHDs actually became an exercise in drive swapping because I had both my acquisitions in three different laptops over a period of six weeks. I have two 17” HP pavilion laptops (the older one fading) and an Acer Aspire. That older HP is now almost nine years old and is being gradually retired but served as one test bed. Both drives were tested in all three and performed beautifully. The final choice was the newer HP which is now my main workstation, and the Aspire which is my transportable photo lab (yeah! think darkroom!). The older HP (I lovingly call the “beast”) has become my lab rat for other projects and now only has one spinning drive.
So I have made my choice and lets look at the short term results.
The newest of my two HP Pavilions. This laptop is no spring chicken. I purchased in new in 2011 and it ran Windows 7 Pro for almost five years. I had always intended it as a replacement for the “beast” (my older HP 17”) and to be a Linux system. However the beast soldiered on and being lazy I did not make the switch. Finally, a major change in my photo equipment forced my hand. My Linux systems running Slackware became less desirable because I needed constantly up-to-date software and wanted an easier update process. Maintaining the latest possible version of digiKam became by itself a very time consuming issue. After considerable testing (basically trial and error) I elected to move to Mint 18.0.
The 17” HP laptop can install two hard drives so I set it up as a hybrid. First I installed a second spinning drive (750Gb) and tested that with already installed Slackware Linux, to ensure no problems. Then I replaced the first hard drive with the smaller of my acquired SSHDs (500 Gb). This drive was then freshly loaded with Mint 18.0.
The result was really gratifying. The boot time went from almost 90 seconds, with all spinning drives, to about 20 seconds with Linux on the SSHD. This performance has been steady now for about two months and I am very pleased.
I use this laptop for email, accounting, writing (this for example) and occasional photo work. Most of my photo editing is done on the portable lab Acer Aspire so I only edit images occasionally on this machine.
The total drive space is over 1.2 Tb of which 750 Gb is spinning and assigned entirely to data. All the OS and software is on the SSHD which speeds up loading. The surprise for me is that working with images on this system is not significantly slower than the Acer Aspire.
This is the Acer Aspire. The second SSHD I acquired is almost 1 Tb. Since the Acer can only accommodate a single drive this was the one choice possible, that it should be the large SSHD.
One of the reasons I looked for SSHDs in the first place arose from massive increases in image data. Recent digital photography advances have cameras using sensors with very large image files. Close to 25 mega pixels for smaller cameras, approaching 50 mega pixels for “full frame” cameras, so called “medium format” camera up to 100 mega pixels. I have not yet gone that far. The images I store currently are about 6-8 Mb for an APS-C sensor and 15-23 Mb for a full frame camera. That is for JPEG images. Both sizes of camera also can take simultaneous RAW images using total storage up to over 40 Mb for a single image. Moving all this image data can be a network killer too! Yes, good cameras are expensive in storage costs. My older camera at 10 mega pixels was not quite so expensive in storage. Greater image color quality, dynamic range and detail does have a cost.
In case the thought has not occurred, you cell phone and tablet shooters are getting up there too!
Once the Acer Aspire was setup with Mint 18.0 I loaded the image viewing and processing software which revels in the faster access. Image loading time are not significant faster so I suspect display is taking more that I realize. For photo aficionados I actually do use all I have loaded! The software includes digiKam, Darktable, GIMP, Gthumb, Gwenview, Krita and various other useful packages.
DigiKam and Darktable are image collection managers. DigiKam also includes excellent editing capability and I tend to use that most.
Gimp and Krita are image editors requiring some education and benefit from user experience. The rest are for viewing.
I was skeptical about the advantages of SSHDs for a basic user like me. When you are used to the performance of spinning drives there does not seem to be a over riding need to change. I now feel differently and am really glad I made the move. Black Friday sales made is possible from a cost point of view. I did spend about sixty hours playing, and installing Linux to select my upgrade, a week (about) of testing time and appropriate stress. Looking back it was time well spent. I am a happy user.
One deduction from this brief experience: if you have multiple drives, upgrade the operating system drive first then put all program files on that drive if possible. In my setup it appears that that is the biggest bang for the buck. If you have sufficient coin left over for another SSHD the choice is less marked but you will gain in faster access and data transfer, it will not be quite so obvious. Bear in mind that most laptops are single drive, fortuitously both the HP 17” Pavilions I have allow two.
I should add that in both final configurations I also placed the Linux “swap area” on the SSHD. I have not yet determined that this actually the route to go, it just seemed a good choice, since I deal with large image files it seemed to me to be the best idea.
The final performance picture is very nice and makes more powerful laptops less a requirement. When you are retired that time is enjoyable and compared to other costs relatively cheap. The whole process was fun. My experience was part of that fun and suggests to me that with SSHDs and Linux almost anyone can easily upgrade a laptop. I was lucky with the sales, what somebody else may pay is likely to be a bit more. It is probably well worth it. I will now consider an SSHD as a logical and highly desirable upgrade, especially when breathing life into an older laptop with Linux. One small caveat: if the laptop is more than 10 years old be very careful as usb and other ports may not be suitable and (as far as I know) there is no IDE SSHD available, there is such a thing in laptops as TOO old!
If I have made this laptop upgrade seem too easy I apologize. Once the decision was made, really it was not a very difficult process. Simple maintenance in any computer usually involves simply changing a component. I encourage people to do that if they have the time and interest. Opening up most laptops is a bit more of a challenge than a desk top unit, good Internet advice is out there for most brands.
To get started look up your laptop on the Internet. You will probably find a You-Tube video or something similar to show how to do what you need. I have seen Acer, HP and others. Unfortunately some are not shown or some are very difficult to dismantle. You can still select the part you need and ask for help to install it. Many forums provide this aid.
Hard drives, memory and batteries are the commonest items needing replacement. Make sure you are getting the correct part, after that
skill with small hand tools is useful. You can get help or at least ask for hints. I have changed screens and keyboards too but that can be a real challenge.
Telling this story has found a number of people like minded. Please do more for yourself, it is fun and success is at least as good as a tonic. If you need help there is an amazing amount on the “net” and you will find a huge amount of support for Linux too. Enjoy!
