Understanding Software Migration. part 1

Enterprise software is going beyond the line in matters of size and scalability; small companies depend on custom tailored software to manage their business rules, and large enterprises with onsite engineers, deal in a daily basis with the challenge to keep their systems up to date and running with the top edge technology.

In both cases the investment made in software systems to assist a given business is elevated, regardless if it was purchased from another company or if it was built and maintained by the own, it’s never going to stop being critical to update the current systems and platforms.

            Any enterprise software owner/designer/programmer must be aware of the market tendencies of operating systems, web technologies, hardware specs, and software patterns and brands; because of the raging nature of the IT industry it takes an eye blink to get obsolete.

Let’s recap about VB6 to VB.NET era, a transition with a lot of new technology, specs and a lot of new capabilities that promise the programmers to take their applications where it seems to be previously impossible like web services and remote facilities, numerous data providers are accessible with a common interface, and more wonders were presented with the .NET framework, however all this features can get very difficult or near to impossible to get incorporated in legacy applications. At this moment it was mandatory to get that software translated to the new architecture.

Initially the idea was to redesign the entire system using those new features in a natural way but this implicates to consume large amounts of resources and human efforts to recreate every single module, class, form, etc. This process results in a completely new application running over new technology that needs to be tested in the final environment, and that will impact the production performance because it has to be tested in the real business challenges. At the end, we got a new application attempting to copycat the behavior of the old programs and huge amount of resources spent.

Since this practice is exhaustive for the technical resources and for the production metrics, the computer scientists research about the functionally equivalent automated processes were used to create software that is capable to port one application from a given source platform to a different, and possibly upgraded one. During this translation process, the main objective is to use as much inherent constructions as possible in the newly generated code to take advantages of the target technology and to avoid the usage of legacy components. In case that the objective is to include a new feature found in the target platform, the application can be migrated and then the feature can be included more naturally than building communication subprograms to make that new capability to get in touch with the old technology.

This process is widely promising because it grants the creation of a new system based on the previous one, using minimum human efforts by establishing transformation rules to take the source constructions and generate equivalent constructions in the desired technology. Nevertheless, this will require human input, especially in very abstract constructions and user defined items.

All the comparisons done before to measure the benefits between redesign and migration, points to identify the second practice as the most cost-effective and fast, but now another metric becomes crucial. The automated stage is done by computers using proprietary technology depending on the vendor of the migration software, but how extensive the manual changes will be? Or, how hard will be to translate the non-migrated constructions?

 

The quality metrics of the final product will be redefined because a properly designed application will be translated with the same design considerations. This means that a given application will be migrated keeping the main aspects of design and the only changes in the resulting source code will be minor improvements in some language constructions and patterns. This makes the new quality metrics to be: maximize the automation ratio, minimize the amount of manual work needed, generate more maintainable code and reach the testing stage faster.

Understanding Software Migration. part 2

 As mentioned previously, the migration process is now an ally of every company while attempting to get their software systems revamped. It’s imperative to determine the rules to measure the process throughput, in order to compare all the options the market offers for this purpose, but, how it comes to be described the rules to compare a process where every single vendor employs proprietary technology that contrast from one to another?

After eye-witness the whole process, the ideas impressed in the user’s mind will decide the judgment made to some specified migration tool, and how it performs; but to make sure this judgment will be fair, here are some concepts, ideas and guidelines about how the migration process should be done, and the most important, how it should be measured.

 

<!--[if !supportLists]-->·        <!--[endif]-->Time:

Human efforts are precious; computer efforts are arbitrary, disposable and reusable. An automated process can be repeated as many times as necessary, as long as their design considerations allow the algorithms to accept all the possible input values. Migration processes can be done with straight one-on-one transformation rules resulting in poorly mapped items that will need small adjustments, but regardless of the size of those efforts, those must be human, so these single reckless rules may become hundreds of human hours to fix all this small issues; remember, we are dealing with large enterprise software products, meaning that a single peaceable imperfection can replicate million times. Another possible scenario will be complex rules that searches for patterns and complex structures to generate equivalent patterns on the other side, but as many AI tasks, it may take lots of computer efforts, because of the immense and boundless set of calculations needed to analyze the original rules and synthesize new constructions. For the sake of performance, the user must identify which resources are most valuable, the time spent by people fixing what the tool’s output provided; or computers time that will be employed by more complex migration tools to generate more human-like code.

 

<!--[if !supportLists]-->·        <!--[endif]-->Translation equivalence:

Legacy applications were built using the code standards and conventions for the moment, the patterns and strategies used in the past have evolved ones for good other to became obsolete. During an automated software migration process there must be a way to adapt arcade techniques to newer ones; a simple one-on-one translation will generate the same input pattern and the resulting source code will not take advantage of all the new features on the target platform. A brilliant migration tool should detect legacy patterns, analyze its usage and look for a new pattern in the target platform that behaves the same way. Because of the time calculations explained previously, a faster tool will only mean non-detailed and superficial transformations that will be a poor replica of the original code or in the best scenario a code wrapper will fix all the damage done. Functional equivalence is the key to a successful migration, because the whole concept of software migration is not only about getting the software running in the target platform, it’s about adaptation to a new set of capabilities and the actual usage of those capabilities.

 

With that on mind, a comparison between different tools can be clearer now. Leaving aside the competitiveness of the market, the readers should identify the facts from the prevaricated marketing slogans, and appraise the resources to be spent during a migration process. Saving a couple of days of computer time may become hundreds of human hours, which at the end will not cure the faulty core, will just make it run.

OSCE supports workshop on irregular migration management and readmission practices in Kazakhstan

An OSCE Programme Office in Astana-supported workshop on international best practices in irregular migration management and readmission procedures for 10 Internal Affairs Ministry and National Security Committee officials started on 6 June 2016 in Astana.

The three-day event was organized by the EU-funded Border Management Programme in Central Asia (BOMCA) in co-operation with the OSCE Programme Office in Astana, the International Organization for Migration (IOM) and Latvia’s State Border Guard. It focused on national legislation and best international practices in dealing with vulnerable groups of migrants passing through borders.

An Office-supported legal analysis of readmission policies was presented along with a draft bylaw to participants who brainstormed ways to further develop the legal and institutional framework. Participants also engaged in an in-depth discussion on readmission as well as countering trafficking of human beings. As a result of the discussions, the participants developed a set of recommendations on amendments to relevant national legislation in line with international best practices.

The workshop is a part of the OSCE Programme Office’s activities related to enhancing the host country’s border security and efficient labour migration management practices.

OSCE States explore role for the Organization regarding migration and refugee flows

VIENNA, 20 July 2016 – Possible roles for the OSCE in the context of the migration and refugee flows across the OSCE area were discussed today at a special meeting of the Permanent Council in Vienna.

The meeting was a milestone in the process launched in March 2016 by Germany’s 2016 OSCE Chairmanship. In a series of seven meetings and following an inclusive approach, an Informal Working Group took stock of the migration-related activities of the OSCE and developed proposals for future engagement. The Working Groups was chaired by Swiss Ambassador to the OSCE Claude Wild and open to all participating States, Partners for-Cooperation and OSCE executive structures as well as a number of international organizations and NGOs.

Presenting results of this ambitious preparatory process Wild said in today’s Permanent Council: “While the current situation is generally referred to as ‘the refugee and migration crisis’, it is in fact a crisis of international migration governance. Comprehensive governance is needed to deal responsibly with the phenomenon of migration and refugee flows. This includes addressing issues of protection, combating crime, border management, successful integration as well as solidarity and partnerships.”

Wild highlighted that the OSCE is uniquely positioned and equipped to use its political convening power and technical expertise to create formal and informal networks. “In such networks national experts and decision makers can exchange best practices in all specific issues that have to be addressed to design and implement responsible national policies on migration and refugee flows,” he said.

Chairperson of the Permanent Council and German Ambassador to the OSCE, Eberhard Pohl, thanked the Swiss OSCE Ambassador and his team for their committed work. “There was a clear common understanding among all OSCE States today that migration and refugee flows figure high on the OSCE agenda in line with its comprehensive approach to security,” Pohl said.

“Given the scale and transnational character of this issue, it is clear that no single country can cope with the challenge of current migration and refugee flows alone. It has to be addressed in a co-operative manner, in a spirit of shared responsibility. We will continue to support OSCE activities in this field and work to further develop the contribution of the OSCE.”

The OSCE Permanent Council is one of the main regular decision-making bodies of the Organization bringing together representatives of all 57 OSCE participating States and the 11 Partners for Co-operation.

Assembly’s work on migration presented to OSCE ambassadors by Ad Hoc Committee Chair Lombardi at special Permanent Council

VIENNA, 20 July 2016 – Presenting the OSCE Parliamentary Assembly’s work concerning the refugee and migrant crisis at a special meeting of the OSCE Permanent Council in Vienna today, Swiss parliamentarian Filippo Lombardi laid out the Assembly’s plan of action going forward, which includes monitoring the situation on the ground and developing policy recommendations for the OSCE and its participating States.

The meeting was convened by the OSCE German Chairmanship to present and discuss the report by Amb. Claude Wild, Chair of the OSCE Informal Working Group Focusing on the Issue of Migration and Refugee Flows. The participants discussed in particular the importance of improving global migration governance and how the OSCE can lend its contribution to promoting regional implementation of a global migration governance architecture.

Lombardi noted that the OSCE PA’s Ad Hoc Committee on Migration, which he chairs, has been active in three main areas, including by organizing field visits, strengthening co-operation with the OSCE and other international actors, and promoting discussions on the migration crisis within the OSCE PA.

“The migration and refugee crisis remains high on the agenda of the OSCE Parliamentary Assembly as highlighted by the importance accorded to this issue in the Tbilisi Declaration adopted at the OSCE PA Annual Session on 5 July,” Lombardi said. “Indeed, the various aspects of this complex issue are addressed in the resolutions of all three general committees as well as in a number of supplementary resolutions” adopted in Tbilisi, he added.

Stressing the need for better communication strategies between governments and the public, Lombardi said that while media plays a fundamental role in shaping public opinion on migration, “political forces bear an equally important responsibility.

“Governments, diplomats and parliamentarians must join forces to tackle the root causes of migration,” he said.

Lombardi further highlighted a recent field visit to camps in Calais and Dunkirk, the Parliamentary Assembly’s contribution to the 27 June meeting of the Informal Working Group, which was addressed by five OSCE parliamentarians, and noted that the PA’s Ad Hoc Committee on Migration met officially for the first timeduring the OSCE PA Annual Session in Tbilisi on 3 July.

In June, the OSCE PA’s then-human rights and humanitarian committee chair, Portuguese parliamentarian Isabel Santos, joined a delegation of the OSCE’s Special Representative and Co-ordinator for Combating Trafficking in Human Beings, Ambassador Madina Jarbussynova, for a visit to Lampedusa, Italy, to an aircraft carrier in the Mediterranean Sea, and to a refugee reception centre in Catania.

Migration will also occupy a prominent position in the discussions of the OSCE PA Autumn Meeting to be held in Skopje from 29 September to 2 October, Lombardi pointed out.

Other than Lombardi’s presentation, today’s special meeting of the Permanent Council included a comprehensive report by Amb. Wild, who noted that addressing the migration crisis requires a multidimensional response based on protection, combating crime, border management, successful integration, and solidarity and partnerships. The OSCE has a number of comparative advantages when addressing migration and refugee flows and is thus uniquely positioned to address this crisis, he emphasized.

Lombardi welcomed the priorities of the OSCE’s Informal Working Group and stressed that members of the PA’s Ad Hoc Committee have agreed to keep in mind the principles identified by this body in carrying out its work.

The Permanent Council and the Ministerial Council are the primary decision-making bodies of the OSCE.

OSCE Presence helps Albanian police better respond to irregular migration

The OSCE Presence in Albania on 24 March 2016 launched a series of workshops for the Albanian border and migration police with the aim of raising their capacity to respond to the challenges of irregular migration, particularly in light of the increased migrant flows through the Western Balkans.

The first of the workshops, which are being organized in close partnership with the Directorate of the Albanian State Police and the General Directorate of Border and Migration, took place in Korça, where 20 border and migration police were trained on measures to be taken to cope with the situation.

The subjects were based on trends as identified by Frontex and EUROPOL, and included migrant routes, the pre-screening of migrants, profiling of possible terrorist fighters, and the detection of criminal offences. The workshop was conducted by experts from the Albanian Europol National Unit and the Albanian Border and Migration Police.

The OSCE Presence, together with its Albanian partners, will organize similar workshops in the coming days with the border and migration police in Gjirokastra and in Shkodra.

From Proxmox to FreeBSD: story of a migration

It’s the start of the work week, so for the IT administrators among us, I have another great article by friend of the website, Stefano Marinelli. This article covers migrating a Proxmox-based setup to FreeBSD with bhyve. The load is not particularly high, and the machines have good performance. Suddenly, however, I received a notification: one of the NVMe drives died abruptly, and the server rebooted. ZFS did its job, and everything remained sufficiently secure, but since it’s a leased server and already several years old, I spoke with the client and proposed getting more recent hardware and redoing the setup based on a FreeBSD host. ↫ Stefano Marinelli If you’re interested in moving one of your own setups, or one of your clients’ setups, from Linux to FreeBSD, this is a great place to start and get some ideas, tips, and tricks. Like I said, it’s Monday, and you need to get to work.

H.323: IPv4 to IPv6 migration

Many networks are migrating from IPv4 to IPv6. What can you do if still have H.323 endpoints that only support IPv4 ?

The GNU Gatekeeper can translate IPv4 into IPv6 calls and vice versa.
You can use one GnuGk to IPv6 enable all of your existing IPv4 endpoints.


 


 

All you have to do is enable IPv6 in your configuration and GnuGk will automatically
detect the connection type of your endpoints and convert the call.

All it takes is one switch in your config:

But today, we examine an alternate history of jazz — one that starts in Africa, then crisscrosses the planet, following the movements of people and empires -- from colonial powers to grassroots revolutionaries to contemporary artists throughout the diaspora.

This history of jazz is like the music itself: fluid and improvisatory.  

In this hour, produced in partnership with the Consortium of Humanities Centers and Institutes (CHCI) — a global consortium of 270 humanities centers and institutes — we hear how both African and African-American music have shaped the sound of the world today.

Mysteries of Migration

If you had to travel 500 miles across country, on foot, with no map, no GPS, without talking to anyone — to a destination you've never seen, could you do it? It sounds impossible, but millions of creatures spend their lives on the move, migrating from one part of the Earth to another with navigation skills we can only dream of. How do they do it — and what can we learn from them?

The curious case of proton migration under pressure in the malonic acid and 4,4'-bi­pyridine cocrystal

In the search for new active pharmaceutical ingredients, the precise control of the chemistry of cocrystals becomes essential. One crucial step within this chemistry is proton migration between cocrystal coformers to form a salt, usually anticipated by the empirical ΔpKa rule. Due to the effective role it plays in modifying intermolecular distances and interactions, pressure adds a new dimension to the ΔpKa rule. Still, this variable has been scarcely applied to induce proton-transfer reactions within these systems. In our study, high-pressure X-ray diffraction and Raman spectroscopy experiments, supported by DFT calculations, reveal modifications to the protonation states of the 4,4'-bi­pyridine (BIPY) and malonic acid (MA) cocrystal (BIPYMA) that allow the conversion of the cocrystal phase into ionic salt polymorphs. On compression, neutral BIPYMA and monoprotonated (BIPYH+MA−) species coexist up to 3.1 GPa, where a phase transition to a structure of P21/c symmetry occurs, induced by a double proton-transfer reaction forming BIPYH22+MA2−. The low-pressure C2/c phase is recovered at 2.4 GPa on decompression, leading to a 0.7 GPa hysteresis pressure range. This is one of a few studies on proton transfer in multicomponent crystals that shows how susceptible the interconversion between differently charged species is to even slight pressure changes, and how the proton transfer can be a triggering factor leading to changes in the crystal symmetry. These new data, coupled with information from previous reports on proton-transfer reactions between coformers, extend the applicability of the ΔpKa rule incorporating the pressure required to induce salt formation.

Crystal structure of N-terminally hexahistidine-tagged Onchocerca volvulus macrophage migration inhibitory factor-1

Onchocerca volvulus causes blindness, onchocerciasis, skin infections and devastating neurological diseases such as nodding syndrome. New treatments are needed because the currently used drug, ivermectin, is contraindicated in pregnant women and those co-infected with Loa loa. The Seattle Structural Genomics Center for Infectious Disease (SSGCID) produced, crystallized and determined the apo structure of N-terminally hexahistidine-tagged O. volvulus macrophage migration inhibitory factor-1 (His-OvMIF-1). OvMIF-1 is a possible drug target. His-OvMIF-1 has a unique jellyfish-like structure with a prototypical macrophage migration inhibitory factor (MIF) trimer as the `head' and a unique C-terminal `tail'. Deleting the N-terminal tag reveals an OvMIF-1 structure with a larger cavity than that observed in human MIF that can be targeted for drug repurposing and discovery. Removal of the tag will be necessary to determine the actual biological oligomer of OvMIF-1 because size-exclusion chomatographic analysis of His-OvMIF-1 suggests a monomer, while PISA analysis suggests a hexamer stabilized by the unique C-terminal tails.
