Vision is the special sense of sight that is based on the transduction of light stimuli received through the eyes. The eyes are located within either orbit in the skull. The bony orbits surround the eyeballs, protecting them and anchoring the soft tissues of the eye. The eyelids, with lashes at their leading edges, help to protect the eye from abrasions by blocking particles that may land on the surface of the eye.
The inner surface of each lid is a thin membrane known as the palpebral conjunctiva. The conjunctiva extends over the sclera, connecting the eyelids to the eyeball. Tears are produced by the lacrimal gland, located beneath the lateral edges of the nose. Tears produced by this gland flow through the lacrimal duct to the medial corner of the eye where the tears flow over the conjunctiva, washing away foreign particles.
Movement of the eye within the orbit is accomplished by the contraction of six extraocular muscles that originate from the bones of the orbit and insert into the surface of the eyeball. Four of the muscles are arranged at the cardinal points around the eye and are named for those locations. They are the: superior rectus, medial rectus, inferior rectus, lateral rectus.
When each of these muscles contracts, the eye moves toward the contracting muscle. For example, when the superior rectus contracts, the eye rotates to look up. The eye itself is a hollow sphere composed of three layers of tissue:
The outermost layer is the fibrous tunic, which includes the white sclera and clear cornea. The sclera accounts for five-sixths of the surface of the eye, most of which is not visible, though humans are unique compared with many other species in having so much of the “white of the eye” visible. The transparent cornea covers the anterior tip of the eye and allows light to enter the eye.
The middle layer of the eye is the vascular tunic, which is mostly composed of the choroid, ciliary body, and iris. The choroid is a layer of highly vascularized connective tissue that provides a blood supply to the eyeball. The choroid is posterior to the ciliary body, a muscular structure that is attached to the lens by zonule fibers. (tiny thread-like fibers that hold the eye's lens firmly in place) These two structures bend the lens, allowing it to focus light on the back of the eye. Overlaying the ciliary body, and visible in the anterior eye, is the iris—the colored part of the eye. The iris is a smooth muscle that opens or closes the pupil, which is the hole at the center of the eye that allows light to enter. The iris constricts the pupil in response to bright light and dilates the pupil in response to dim light.
The innermost layer of the eye is the neural tunic, or retina, which contains the nervous tissue responsible for photoreception.
The eye is also divided into two cavities: The anterior cavity and the posterior cavity. The anterior cavity is the space between the cornea and lens, including the iris and ciliary body. It is filled with a watery fluid called the aqueous humor. The posterior cavity is the space behind the lens that extends to the posterior side of the interior eyeball, where the retina is located. The posterior cavity is filled with a more viscous fluid called the vitreous humor.
The retina is composed of several layers and contains specialized cells for the initial processing of visual stimuli. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. The change in membrane potential alters the number of neurotransmitters that the photoreceptor cells release onto bipolar cells in the outer synaptic layer. It is the bipolar cell in the retina that connects a photoreceptor to a retinal ganglion cell (RGC) in the inner synaptic layer. There, amacrine cells additionally contribute to retinal processing before an action potential is produced by the RGC. The axons of RGCs, which lie at the innermost layer of the retina, collect at the optic disc and leave the eye at the optic nerve. Because these axons pass through the retina, there are no photoreceptors at the very back of the eye where the optic nerve begins. This creates a “blind spot” in the retina and a corresponding blind spot in our visual field.
Photoreceptors in the retina (rods and cones) are located behind the axons, RGCs, bipolar cells, and retinal blood vessels. A significant amount of light is absorbed by these structures before the light reaches the photoreceptor cells. At the exact center of the retina is a small area known as the fovea. At the fovea, the retina lacks the supporting cells and blood vessels, and only contains photoreceptors. Therefore, visual acuity is greatest at the fovea. This is because the fovea is where the least amount of incoming light is absorbed by other retinal structures. As one moves in either direction from this central point of the retina, visual acuity drops significantly.
There are three types of cone opsins that are sensitive to different wavelengths of light and provide us with color vision. By comparing the activity of the three different cones, the brain can extract color information from visual stimuli. For example, a bright blue light that has a wavelength of approximately 450 nm would activate the “red” cones minimally, the “green” cones marginally, and the “blue” cones predominantly. The relative activation of the three different cones is calculated by the brain, which perceives the color as blue. However, cones cannot react to low-intensity light, and rods do not sense the color of light. Therefore, our low-light vision is, in essence, in grayscale. In other words, in a dark room, everything appears as a shade of gray. If you think that you can see colors in the dark, it is most likely because your brain knows what color something is and is relying on that memory.

Aristoteles befasst sich mit der Frage nach der idealen Staatsform, deren Ziel das gute Leben sein soll. Dazu erläutert er zunächst die Zusammensetzung des Staates. Nach Aristoteles ist der Mensch ein „zoon politikon“, also ein staatenbildendes Wesen. Der Mensch ist von Natur aus Teil einer Gemeinschaft.
Die kleinste Einheit im Staat bildet das Haus, das aus Mann und Frau bzw. Herr und Diener besteht. Die über einen Tag hinausreichenden Bedürfnisse erfüllt das Dorf, das sich aus Häusern zusammensetzt. Mehrere Dörfer bilden den Staat. Außerhalb der Gemeinschaft kann nur ein schlechtes Wesen oder ein göttliches Wesen leben.
Um darzulegen, welche Regierungsform die beste ist, vergleicht Aristoteles zunächst gute und schlechte Verfassungen. Gute Verfassungen, wie die Monarchie, Aristokratie und Politie, handeln zum Wohl der Gemeinschaft, während schlechte Regierungen wie Tyrannei, Demokratie oder Oligarchie nur den eigenen Vorteil im Blick haben.
Als beste Regierungsform erkennt Aristoteles die Politie, in der die Mittleren herrschen. Diese Mittleren verfügen über ein mittleres Vermögen, wodurch sie nicht zu unterwürfig und nicht profitorientiert sind. Aristoteles ist der Auffassung, dass man am besten der Vernunft gehorcht, wenn man genug zum Leben hat und der Gemeinschaft dient.
Along with audition, the inner ear is responsible for encoding information about equilibrium. The cells that sense head position, head movement, and body motion are located within the vestibule of the inner ear. Head position is sensed by otolith organs, (the two membranous sacs of the vestibule, the utricle and the saccule) whereas head movement is sensed by the semicircular canals. The neural signals generated in the vestibular ganglion are transmitted through the vestibulocochlear nerve to the brainstem and cerebellum.
Rotational Coding by Semicircular Canals. Rotational movement of the head is encoded by the hair cells in the base of the semicircular canals. As one of the canals moves in an arc with the head, the internal fluid moves in the opposite direction, causing the cupula (a gelatinous membrane overlying the crista ampullaris of the semicircular canal) and stereocilia (miniscule hair-like protrusions on the surface of sensory cells) to bend. The movement of two canals within a plane results in information about the direction in which the head is moving, and activation of all six canals can give a very precise indication of head movement in three dimensions.
Somatosensation is considered a general sense, as opposed to the special senses discussed in this section. Somatosensation is the group of sensory modalities that are associated with touch, proprioception, (sense movement, action and location) and interoception. (the perception of internal signals from the body) These modalities include pressure, vibration, light touch, tickle, itch, temperature, pain, proprioception, and kinesthesia. This means that its receptors are not associated with a specialized organ, but are instead spread throughout the body in a variety of organs. Many of the somatosensory receptors are located in the skin, but receptors are also found in muscles, tendons, joint capsules, ligaments, and in the walls of visceral organs.
The two types of somatosensory signals that are transduced by free nerve endings are pain and temperature. Temperature receptors are stimulated when local temperatures differ from body temperature. Some thermoreceptors are sensitive to just cold and others to just heat. Nociception is the sensation of potentially damaging stimuli. Mechanical, chemical, or thermal stimuli beyond a set threshold will elicit painful sensations. Stressed or damaged tissues release chemicals that activate receptor proteins in the nociceptors.
For example, the sensation of heat associated with spicy foods involves capsaicin, the active molecule in hot peppers. Capsaicin molecules bind to a transmembrane ion channel in nociceptors that is sensitive to temperatures above 37°C (98.6°F). The dynamics of capsaicin binding with this transmembrane ion channel are unusual in that the molecule remains bound for a long time. Because of this, it will decrease the ability of other stimuli to elicit pain sensations through the activated nociceptor. For this reason, capsaicin can be used as a topical analgesic, such as in products such as Icy Hot.
Rule
Subject matter jurisdiction is the power of a court to hear a type of case. Proper subject matter jurisdiction based on federal question jurisdiction can be achieved by satisfying constitutional requirements of Article III, Section 2; and statutory requirements of sections 1331. Constitutional authority arises from Article III, Section 2, to have jurisdiction over claims “arising under this Constitution, the laws if the United States, and treaties made, or which may be made, under their authority.” The statutory requirement is provided by Section 1331, “the district courts shall have original jurisdiction over all civil actions arising under the Constitution, the laws, and the treaties of the United States.”
Application
Constitutional authority arises from Article III, Section 2, giving the courts jurisdiction over claims “arising under this Constitution, the laws if the United States, and treaties made, or which may be made, under their authority.” This has been interpreted in Osborne as simply having a part of the case related to federal law, or simply put, a “federal ingredient.” [apply]. [conclude].
The statutory requirement is provided by Section 1331, “the district courts shall have original jurisdiction over all civil actions arising under the Constitution, the laws, and the treaties of the United States.” This is interpreted much more strictly than the Constitutional requirement. Under 1331, the Holmes Creation Test was created by Justice Holmes in American Well Works, and requires that the federal issue must give rise to the right of action. [apply]. As used in Mottley, the well pleaded complaint rules requires the federal issue to be in the claim, and the federal issue being part of an anticipated defense is insufficient. [apply]. [conclude].
If a plaintiff brings a state law claim that does not satisfy the creation test, the Essential Federal Ingredient Test, which has authority from Grable, can be used to determine if the court should have subject matter jurisdiction. The elements of this test are that the state law claims raises a necessary federal issue, is disputed, is substantial, and does not upset the congressionally approved balance of responsibility. [mini IRAC/apply facts for each factor contested]. [conclude].
The first factor is whether or not the federal issue is necessarily raised. This is that the resolution of the federal issue is required to reach an outcome in the case. [apply]. The next factor is whether or not the issue is actually disputed. [apply]. The third factor is whether the issue is substantial. This is based on the importance of the resolution of the issue to the federal system as a whole, and is exemplified in Gunn, where a patent issue arising from a legal malpractice claim is not substantial. [apply]. The last factor is whether the adjudication of the issue in federal court will upset the congressionally approved balance of responsibilities between the state and federal courts. In Gunn, this factor was against the resolution of the issue in federal court because it would open opportunity for other plaintiffs to bring legal malpractice claims in the federal court system. [apply]. [conclude].
Rule
For a court to have proper personal jurisdiction over a party, the court must have appropriate authority and remain within the constitutional due process limits of the traditional bases or minimum contacts analysis. Pennoyer. A state court requires a grant of state authority, which may be from long arm statutes. The minimum contacts analysis is sufficient for constitutional personal jurisdiction when the party shows purposeful availment and the claim’s relation to the frum state creates a presumption of constitutionality, unless deemed unreasonable by the Gestalt factors. A party may be subject to personal jurisdiction when they have certain minimum contracts such that the maintenance of suit would not offend the traditional notions of fair play and substantial justice. Without personal jurisdiction, a court lacks the power to give a valid judgement on the case. Article 4, Section 1 is the full faith and credit clause, which says that the state courts must give full faith and credit to judgments of other state courts when judgement is valid. Similarly, U.S. Code Section 1738 says that the federal courts must give full faith and credit to the state courts’ valid judgements. When a court lacks proper personal jurisdiction, the judgement is invalid, like seen in Pennoyer.
Application
For personal jurisdiction to be proper, the state court must have appropriate authority, which comes from state statute. [apply]. [conclude].
Personal jurisdiction is presumed constitutional when contacts with a forum show purposeful availment and relatedness, but this presumption can be overcome by other factors of unreasonableness. Purposeful availment is the quality and nature of contacts that is systematic and continuous. Such contacts means the individual has availed themself to the protection of state laws, and their activity may give rise to potential liability. International Shoe. [apply]. In addition to purposeful availment, there must be relatedness of the claim to the contacts. The claim must demonstrate affiliation with the contacts that the individual has with the state. Bristol-Myers Squibb. [apply]. [conclude].
Although purposeful availment and relatedness create a presumption of constitutionality, it can be overcome by the Gestalt factors if the exercise of personal jurisdiction would be otherwise unreasonable. These factors are the burden on the defendant, the plaintiff’s interest in convenient and effective relief, the forum’s interest in resolving the conflict, the judicial system’s interest in obtaining effective relief, and the common interests of all sovereignties in maintaining substantive justice. [apply]. [conclude]
A consent letter is a formal document that requests or grants permission for a specific action, event, or procedure. It's a legal document that indicates that the person providing the letter understands the risks and implications of the activity or procedure and has given their informed consent.
Rule
Personal jurisdiction is proper when the court is granted proper authority and the exercise of jurisdiction is within constitutional limits of the due process clause. Pennoyer. As a federal court, proper personal jurisdiction requires federal authority which comes from Rule 4(k)(1). For a court to be within the constitutional due process limits when exercising general jurisdiction over a corporation, the forum state must be the corporation’s state of incorporation, principal place of business, or where it has such contacts that it is “essentially at home.” Ford.
Application
For proper personal jurisdiction, a federal court requires a federal grant of authority, which comes from Rule 4(k)(1). Rule (4)(k)(1) states that the federal courts can have personal jurisdiction when the individual or corporation is under the personal jurisdiction of the state court of general jurisdiction where the federal court is located. This means that when a state court has proper jurisdiction, the federal court does as well. One way for a state court to have personal jurisdiction is by long arm statute. Long arm statutes can be either tailored or due process. [apply]. [conclude].
The court must also remain within the constitutional limits of the due process clause. The due process clause says that no state shall “deprive any person of life, liberty, or property without due process of law.” General jurisdiction allows personal jurisdiction over a corporation even if the claims are not related to the state or the corporation’s contacts with the state. This applies where a corporation is incorporated, where it has its principle place of business, or where it is “essentially at home.” Ford. The paradigm examples of general personal jurisdiction over corporations are where the state of incorporation is and where the principal place of business is, and these are equivalent to the domicile of an individual. Daimler. [apply]. When looking at whether a corporation is “essentially at home,” the contacts are to be measured in relation to the entirety of the corporation’s activities. BNSF. This third option, where a corporation’s activities are so systematic and continuous that it is “essentially at home” is an exceptional case. Daimler. Such activities are to be measured relative to the entirety of the corporation’s activities. BNSF. [apply]. Furthermore, a corporation may be consenting to personal jurisdiction of a state when a statute requires the corporation to register for operation. Mallory. [apply]. [conclude].
Rule:
For personal jurisdiction to be proper, a federal court must have federal authority to exercise such jurisdiction and be within constitutional limits. Pennoyer. The federal court must have federal authority, which can come from Rule 4(k)(1). Rule 4(k)(1) states that a federal court can have personal jurisdiction over someone who is served a summons or waiver of service and is under any of the categories of: (A) within the jurisdiction of the state court of general jurisdiction of the state the court is located in; (B) is joined by Rule 14 or 19 and is within 100 miles of where the court is; or (C) if permitted by statute.
The second requirement for personal jurisdiction to be proper for the court to be within constitutional limits. To be within constitutional limits, a court must establish the jurisdiction by one of the traditional bases of domicile, tag, service on an agent, or in rem. The traditional bases are based on the rule of territoriality, which is a rule that gives states sovereignty over the land, people, and property within its borders. The court in Pennoyer, a case between a California resident and an Oregon resident, affirmed the rule of territoriality by invalidating Neff v. Mitchell. Neff v. Mitchell was overturned because the court did not exercise proper personal jurisdiction. Lastly, he did own land in Oregon but the attachment of this land to the case was not until the end, so in rem jurisdiction was not valid.
Application:
The first step in determining if the federal court has personal jurisdiction over an individual is evaluating if exercising jurisdiction would be within the authority given by Rule 4(k)(1). Rule 4(k)(1)(A) means that a person who is within the statutory personal jurisdiction of a state court can be within the granted authority for personal jurisdiction of the federal court. States may have tailored or due process long arm statutes. [apply]. [conclude].
After the statutory requirement is met, there is also a due process requirement. The due process clause says a state cannot “deprive any person of life, liberty, or property without due process of the law.” Within this requirement, there are two types of jurisdiction, general and specific. General jurisdiction is proper over those domiciled in the state, while specific jurisdiction can include tag, service on an agent, consent, and in rem.
The first approach is general jurisdiction, which can be determined by an individual’s domicile. Federal courts can have constitutional personal jurisdiction over an individual who is domiciled in that state. The state that someone is domiciled in is the state that they intend to reside in indefinitely. [apply]. [conclude].
Under specific jurisdiction, there are more approaches, and this includes tag service. Tag is a traditional basis on which the court can have personal jurisdiction when a defendant is served a summons and complaint in the state’s border. [apply]. [conclude].
Another specific jurisdiction basis is service on an agent. The court can have personal jurisdiction over an individual when the person appoints an agent to receive process of service, and when that agent receives service in that state. [apply]. [conclude].
Personal jurisdiction can also be within constitutional limits when the defendant consents to the court’s jurisdiction. The consent basis establishes that a court can have personal jurisdiction over an individual who has contractually agreed to the court’s jurisdiction or who has voluntarily appeared in court. [apply]. [conclude].
The last basis for personal jurisdiction is in rem. In rem is different from the previously explained bases because it is the court’s exercise of power over a piece of property, not the individual themself. As applied in Pennoyer, the attachment of the property to the suit must be at the start. [apply]. [conclude].

Rule:
Federal Rules of Civil Procedure Rule 12(b)(6) allows dismissal for failure to state a claim upon which relief can be granted. This dismissal is for failure to satisfy Rule 8(a)(2), “short and plain statement showing that the pleader is entitled to relief.” As established by Conley, a pleader does not need to provide factual detail for the claim. In Conley and Leatherman, the courts establish that despite the lack of requirement to set out a claim in detail, the claim does need to provide fair notice of the claim and the grounds upon which it rests. The court in Iqbal establishes that a pleader can plead intent only generally under Rule 9(b), but this is not a reason to ignore the requirement of Rule 8(a)(2). In the pleading process, a pleader must provide sufficient factual allegations, that will be presumed to be true, to state a claim that is plausible on its face. The court in Iqbal follows a three-step process to analyze a pleader’s claim is sufficient under Rule 8(a)(2). The three steps are (1) identifying the right of action and its elements; (2) identifying allegations that are conclusory and setting them aside so the nonconclusory allegations remaining can be given the presumption of truth; (3) and then assessing whether the presumed true allegations support the right of action directly or by inference.
Application:
The first step of the three-part analysis from Iqbal is determining the right of action and its elements. In the present case, the right of action is _______ and the elements of _________ are ________.
The second of the three steps is separating conclusory allegations and giving the remaining allegations the presumption of truth. Iqbal gives further explanation of what this means. Allegations that are unadorned accusations, mere labels and formulaic recitations, and naked assertions devoid of facts are all insufficient. Iqbal. [apply]. [conclude].
The third and final step of the analysis is comparing the remaining allegations to the right of action and its elements, and assessing whether they move the claim from conceivable to plausible. Even when the judge is skeptical of the party’s ability to find evidence for an allegation, the allegation can still be given the presumption of truth and the party will have the chance to find evidence in discovery. Iqbal. When assessing a claim, the judge will use judicial experience and common sense to consider whether there are more common alternative explanations. Iqbal. Even if the allegations of a complaint match the elements of a right of action, more likely explanations make them insufficient. Twombly, Iqbal. [apply]. [conclude].
Lucy loved watching the butterflies flutter around her wildflower garden in the warm summer sun. She used a watering can to gently water the plants, making sure every flower had enough to drink. Suddenly, a shiny blue dragonfly landed on her watering can, and Lucy couldn’t believe how pretty it looked up close!

DevOps is een werkmethodologie die in bedrijven steeds vaker wordt toegepast om de samenwerking tussen development- en operationsteams te verbeteren. In veel organisaties worden deze twee afdelingen traditioneel gescheiden, wat kan leiden tot communicatieproblemen, inefficiënties en vertragingen in projecten. DevOps probeert deze problemen op te lossen door een cultuur te creëren waarin samenwerking, automatisering en continue verbetering centraal staan. Het uiteindelijke doel is om software sneller en betrouwbaarder te ontwikkelen, testen en implementeren.
Een belangrijk aspect van DevOps is de integratie van tools en processen. Bijvoorbeeld, continuous integration en continuous delivery (CI/CD) zijn kernprincipes binnen DevOps. Bij continuous integration wordt de code van verschillende ontwikkelaars regelmatig samengevoegd in een gedeelde repository, waar automatische tests worden uitgevoerd. Dit helpt om fouten vroegtijdig te detecteren en voorkomt dat kleine problemen later in het proces grote complicaties veroorzaken. Continuous delivery gaat nog een stap verder door ervoor te zorgen dat de software op elk moment kan worden geïmplementeerd. Dit vereist een hoge mate van automatisering in het build-, test- en implementatieproces.
Binnen een bedrijf dat DevOps omarmt, spelen ook afspraken en communicatie een cruciale rol. Het is belangrijk dat alle betrokken teams duidelijke doelstellingen hebben en op dezelfde manier werken. Dit kan bijvoorbeeld worden bereikt door regelmatige stand-up meetings te houden, waarin teamleden kort bespreken waar ze mee bezig zijn, welke problemen ze tegenkomen en welke prioriteiten er zijn. Daarnaast is het gebruik van een gedeelde projectmanagementtool, zoals Jira of Trello, vaak nuttig om taken te organiseren en voortgang te monitoren.
Naast de technische en organisatorische aspecten, benadrukt DevOps ook de menselijke kant. Een cultuur van vertrouwen en wederzijds respect is essentieel om de samenwerking te verbeteren. Teamleden moeten zich vrij voelen om ideeën te delen, vragen te stellen en fouten toe te geven zonder angst voor negatieve consequenties. Dit kan worden gestimuleerd door trainingen te organiseren, informele teambuildingactiviteiten te plannen en een open communicatiebeleid te hanteren.
Een ander belangrijk onderdeel van DevOps is monitoring en feedback. Het is essentieel dat bedrijven inzicht hebben in de prestaties van hun systemen, zowel tijdens de ontwikkeling als na de implementatie. Door gebruik te maken van monitoringtools zoals Prometheus, Grafana of Splunk, kunnen teams problemen snel identificeren en oplossen voordat ze de gebruikers beïnvloeden. Feedback van klanten en eindgebruikers speelt ook een grote rol. Deze feedback kan worden gebruikt om toekomstige releases te verbeteren en beter aan te sluiten op de behoeften van de markt.
In veel bedrijven wordt DevOps niet van de ene op de andere dag ingevoerd. Het is een proces dat tijd en toewijding vereist. Het kan beginnen met kleine stappen, zoals het automatiseren van een enkel proces of het organiseren van workshops om de samenwerking tussen teams te verbeteren. Naarmate de voordelen van deze aanpak duidelijker worden, kan de DevOps-mentaliteit zich door het hele bedrijf verspreiden.
Samenvattend biedt DevOps een waardevolle aanpak voor bedrijven die hun softwareontwikkeling willen versnellen, hun systemen betrouwbaarder willen maken en een betere samenwerking tussen teams willen bevorderen. Het succes van DevOps hangt echter niet alleen af van de tools en processen, maar ook van de bereidheid van mensen om samen te werken, te leren en zich aan te passen aan veranderingen.
DevOps en software-installatie zijn belangrijke onderdelen van moderne softwareontwikkeling en IT-beheer. Laten we deze onderwerpen wat dieper bekijken.
Wat is DevOps?
DevOps (Development and Operations) is een methode en cultuur die samenwerking tussen ontwikkelaars en IT-operationele teams bevordert om software sneller, efficiënter en betrouwbaarder te leveren. Het integreert processen, tools en praktijken die teams in staat stellen om:
1. Sneller te ontwikkelen en implementeren: Door middel van continue integratie (CI) en continue levering (CD).
2. Hoge kwaliteit te waarborgen: Met behulp van geautomatiseerd testen en monitoring.
3. Samenwerking te verbeteren: Door het afbreken van silo’s tussen ontwikkelings- en operationele teams.
4. Feedbackcycli te versnellen: Om problemen snel te detecteren en op te lossen.
Belangrijke tools in DevOps zijn bijvoorbeeld:
• Git voor versiebeheer
• Jenkins of GitLab CI/CD voor automatisering
• Docker en Kubernetes voor containerisatie en orkestratie
• Ansible, Puppet, of Terraform voor configuratiebeheer
Wat houdt software-installatie in?
Software-installatie verwijst naar het proces van het implementeren en configureren van een softwaretoepassing op een computer of server. Het kan handmatig of geautomatiseerd worden gedaan, afhankelijk van de schaal en vereisten.
Handmatige installatie
• Downloaden: Het verkrijgen van de software van een bron, zoals een officiële website of repository.
• Installeren: Het uitvoeren van installatieprogramma’s, zoals .exe op Windows of pakketmanagers zoals apt of yum op Linux.
• Configureren: Het instellen van parameters om de software naar wens te laten werken.
Geautomatiseerde installatie
• Gebruik maken van scripts, zoals Bash, Python, of tools zoals Ansible om meerdere systemen snel en consistent te configureren.
• Containerisatie: Met tools zoals Docker kan software worden verpakt in containers met alle afhankelijkheden, zodat ze overal draaien waar Docker beschikbaar is.
• Orkestratie: Kubernetes wordt vaak gebruikt om containers op schaal te beheren.
Overlap tussen DevOps en software-installatie
DevOps-methodologieën maken vaak gebruik van geautomatiseerde software-installatie. Bijvoorbeeld:
• Het installeren en configureren van applicaties in containers via CI/CD-pipelines.
• Het automatisch schalen en updaten van applicaties met orkestratietools.
• Het implementeren van software met Infrastructure as Code (IaC), waarmee servers en omgevingen geconfigureerd kunnen worden als herhaalbare scripts.

APA Citation Basics
When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998). One complete reference for each source should appear in the reference list at the end of the paper.
If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference.
On the other hand, if you are directly quoting or borrowing from another work, you should include the page number at the end of the parenthetical citation. Use the abbreviation “p.” (for one page) or “pp.” (for multiple pages) before listing the page number(s). Use an en dash for page ranges. For example, you might write (Jones, 1998, p. 199) or (Jones, 1998, pp. 199–201). This information is reiterated below.
Regardless of how they are referenced, all sources that are cited in the text must appear in the reference list at the end of the paper.
De root server, TLD server, en authoritative server zijn essentiële componenten van het Domain Name System (DNS). Ze werken samen om domeinnamen zoals www.example.com te vertalen naar IP-adressen die door computers worden gebruikt. Hier volgt een gedetailleerde uitleg van hun rollen:
1. Root Server
De root servers vormen het beginpunt van elke DNS-oplossing. Ze zijn de bovenste laag in de DNS-hiërarchie en bevatten informatie over welke Top-Level Domain (TLD) servers verantwoordelijk zijn voor specifieke domeinen.
• Functie:
Wanneer je een domein invoert, zoals www.example.com, en je apparaat het bijbehorende IP-adres niet weet, stuurt het een verzoek naar een root server. De root server verwijst je naar de juiste TLD server (bijvoorbeeld voor .com, .org, of .nl).
• Kenmerken:
• Er zijn 13 hoofdgroepen van root servers wereldwijd, beheerd door verschillende organisaties (zoals ICANN en Verisign).
• Deze servers zijn niet fysiek beperkt tot 13 locaties. Dankzij Anycast worden ze wereldwijd op honderden locaties gedupliceerd voor snelheid en betrouwbaarheid.
• Belangrijkheid:
Root servers slaan zelf geen IP-adressen van domeinen op. Ze zorgen alleen voor het doorverwijzen naar de juiste TLD servers.
2. TLD Server
De TLD servers beheren informatie over specifieke Top-Level Domains, zoals .com, .org, .net, of landenspecifieke TLD’s zoals .nl (Nederland).
• Functie:
Wanneer de root server je doorverwijst, stuurt je apparaat een verzoek naar de juiste TLD server. Voor www.example.com zou dat bijvoorbeeld de .com TLD server zijn. Deze server geeft vervolgens informatie over de authoritative server die de specifieke domeinnaam beheert.
• Kenmerken:
• Elke TLD heeft zijn eigen reeks servers, vaak beheerd door registries zoals Verisign voor .com en SIDN voor .nl.
• TLD servers bevatten geen gedetailleerde records, maar alleen verwijzingen naar authoritative servers.
3. Authoritative Server
De authoritative servers zijn de laatste en meest specifieke stap in het DNS-proces. Ze bevatten de exacte gegevens over een domeinnaam, inclusief het bijbehorende IP-adres.
• Functie:
Zodra je apparaat de authoritative server heeft bereikt, vraagt het deze server om het IP-adres van de gevraagde domeinnaam (www.example.com). De authoritative server geeft dit IP-adres terug aan je apparaat.
• Kenmerken:
• Elke domeinnaam wordt beheerd door een specifieke authoritative server, vaak eigendom van een hostingprovider of het bedrijf dat de domeinnaam heeft geregistreerd.
• Deze servers bevatten resource records (RR’s), zoals:
• A-records: Voor IPv4-adressen.
• AAAA-records: Voor IPv6-adressen.
• MX-records: Voor e-mailservers.
• CNAME-records: Voor aliassen van domeinen.
• Belangrijkheid:
De authoritative server is de bron van waarheid voor een domein. Alle andere DNS-servers (bijvoorbeeld caching resolvers) vertrouwen op de gegevens van deze server.
Samenvatting van de samenwerking
1. Root Server: Geeft informatie over welke TLD server verantwoordelijk is voor de gevraagde domeinextensie.
2. TLD Server: Verwijst naar de juiste authoritative server voor het specifieke domein.
3. Authoritative Server: Geeft het daadwerkelijke IP-adres van het gevraagde domein terug.
