Presentation delivered in the Workshop on Art and Architecture. Second Annual SHARE Conference London, 11-12 May 2012. Hosted by CCW Graduate School, University of the Arts London. More information at:http://arc.housing.salle.url.edu/share_workshop_transdisciplinarity/
Presentation of the research work of the group ARC Engineering and Architecture La Salle about energy information systems for buildings and cities based on semantic technologies. The presentation was given at the Universidad de Deusto, Bilbao, on 27 April, 2016, as part of the activities of the Opencitydata thematic network.
This is a summary of the development of the BARCODE HOUSING SYSTEM, a project carried out by the research group ARC Engineering and Architecture La Salle, from 2002 to 2009. The purpose of the research has been the creation of an Internet-based environment which facilitates the interaction of the different actors (architects, builders, manufacturers, occupants, facilities managers) involved in the design, construction and use of affordable housing built with industrialized methods. This research project began in 2002, when we started to develop a rule-based system to automatically generate housing units and buildings resulting from their aggregation, by means of user-friendly interfaces. This system, which was completed in 2005, was stand-alone and limited to single users. We then proceeded to develop a new environment to overcome these limitations, facilitating the participation and interaction of different agents in the process of designing, building and using the housing generated with the support of the system. This second version of the system was carried out with a research grant of the Spanish National RDI plan, from 2005 to 2009. It is a modular environment which supports the decision-making process in an open and distributed fashion, allowing inputs from different users at any stage of the design and building process.
A poster of the first version of the system can be accessed here:

Evidence Tracking
Evidence is essential to solving any case and proving the guilt of an offender in a court of law. Once a crime has been reported the first step of the responding officer is to secure the crime scene to ensure it is properly preserved until forensic investigators can arrive on the scene. The evidence collection process begins with thoroughly documenting the crime scene. The process begins with a walk through of the crime scene in order to identify potential evidence and to develop an idea of what occurred at the crime scene. Once the evidence has been identified the evidence collection process will begin with collecting evidence that is fragile or easily damaged or destroyed.
In the rape scenario DNA evidence is crucial to proving a crime occurred and showing the guilt of the offender. Rape cases are hard to prosecute and require physical evidence to prove the act of rape even occurred. In a majority of cases it is the word of the victim against the word of the perpetrator. DNA evidence can provide conclusive evidence that a sexual assault occurred and point to the guilty offender. In the rape scenario evidence that was located and will need to be collected is the semen on the comforter and the tissue located in the trash can. This evidence can contain valuable DNA that points directly to the offender. The semen and the tissue can contain the DNA profile of the offender and the tissue.
The evidence collection process begins first by identifying the evidence in a walk through and then properly documenting the evidence. Documenting the evidence is an essential step in the collection process. This begins with photographing the evidence where it sits in order to show the court where the evidence was located and in what condition. Once the evidence has been photographed it must be collected using uniform collection standards. The comforter that was located contained a semen stain that must be collected in order to develop DNA on the criminal suspect. Most items of evidence will be collected in paper containers such as packets, envelopes, and bags and liquid items can be transported in non-breakable, leak proof containers (Schiro, 2006).
When collecting DNA from the comforter the forensic technician will mark the wet stain with a permanent marker in order to make it easier to locate during the DNA analysis. The technician will then wait for the comforter to air dry before placing it in a clean package and properly sealing and documenting for transportation. The second piece of evidence that was located at the crime scene was a tissue in a waste paper basket. The tissue will need to be collected using a pair of tweezers or using a pair of gloves and then be placed in a plastic container. The plastic container will need to be sealed and then properly documented for transportation.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.

2. CRIME SCENE: Any physical location in which a crime has occurred or is
suspected of having occurred.
Source: http://www3.sc.maricopa.edu/ajs/crime_scene_technician.htm
PRIMARY CRIME SCENE: The original location of a crime or
accident.
SECONDARY CRIME SCENE: An alternate location where
additional evidence may be found.
ALIBI: Statement of where a suspect was at the time of a crime.
ACCOMPLICE: Person associated with someone suspected of committing a crime.
SUSPECT: Person thought to be capable of committing a crime.
Crime Scene Vocabulary
3. Testimonial evidence includes oral or written statements given to police as well as
court testimony by people who witnessed an event.
Physical evidence refers to any material items that would be present at the crime
scene, on the victims, or found in a suspect’s possession.
Trace evidence refers to physical evidence that is found in small but measurable
amounts, such as strands of hair, fibers, or skin cells.
Source: http://www3.sc.maricopa.edu/ajs/crime_scene_technician.htm
What will evidence collected at a scene do for the investigation?
• May prove that a crime has been committed
• Establish key elements of a crime
• Link a suspect with a crime scene or a victim
• Establish the identity of a victim or suspect
• Corroborate verbal witness testimony
• Exonerate the innocent.
• Give detectives leads to work with in the case
Types of Evidence
4. POLICE OFFICERS are typically the first to arrive at a crime scene. They are
responsible for securing the scene so no evidence is destroyed and detaining
persons of interest in the crime.
The CSI UNIT documents the crime scene in detail and collects any physical
evidence.
The DISTRICT ATTORNEY is often present to help determine if any search
warrants are required to proceed and obtains those warrants from a judge.
The MEDICAL EXAMINER (if a homicide) may or may not be present to
determine a preliminary cause of death.
SPECIALISTS (forensic entomologists, anthropologists, or psychologists) may be
called in if the evidence requires expert analysis.
DETECTIVES interview witnesses and consult with the CSI unit. They
investigate the crime by following leads provided by witnesses and physical
evidence.

Crime Scene Personnel
5. Step 1: Interview
The first step in investigating a crime scene is to interview the first officer at the scene or the
victim to determine what allegedly happened, what crime took place, and how was the
crime committed. This information may not be factual information but it will give the
investigators a place to start.
Step 2: Examine
The second step in the investigation of a crime scene, which will help identify possible
evidence, identify the point of entry and point of exit, and outline the general layout of the
crime scene.
Step 3: Document
The third step in the protocol involves creating a pictorial record of the scene as well as a
rough sketch to demonstrate the layout of the crime scene and to identify the exact
position of the deceased victim or other evidence within the crime scene.
Step 4: Process
This is the last step in the protocol. The crime scene technician will process the crime scene
for evidence, both physical and testimonial evidence. It is the crime scene technicians
responsibility to identify, evaluate and collect physical evidence from the crime scene for
further analysis by a crime laboratory.
