Java Collection is a pretty favorite subject in Java articles. But here, I’ll share my personal thoughts and ideas that you might not know.
From the first look, Java Collection is a set of structures that fit different problems, like quick data search. But in practice, Java Collection interfaces are representing notions from discrete math.

This week Google announced further details of its plan to remove cookies from ad tracking. The strategy, which the ad giant expects to be fully implemented by 2022, has come about due to increasingly stringent privacy laws in a growing number of territories around the globe.
Google’s first step was the announcement in January of FLoC (Federated Learning of Cohorts). Google itself is still testing and fine-tuning the system, but in essence, Google will replace 3rd-party cookies in Chrome with groups of anonymized users.
Critics of the plan have questioned whether users will be genuinely anonymous or whether Google will be tracking individuals to group them properly. The answer came earlier this week in a low-key announcement of KaST.
KaST (Key and Surface Tracking) is the first iteration of Google’s new tracking technology. It works entirely without cookies and is fully device-agnostic.
The technology behind KaST is surprisingly old. It was first trialed in 1987 as a simple process for auditing the input of stenographers. Although the latest version of the technology draws heavily on voice recognition software algorithms, the original version of KaST — software named TAAA (Typist Account Accuracy Audit) — predates modern voice recognition by at least two years.
KaST uses…biomechanical and cognitive patterns, identifying individual users based on their keystrokes.
Just as your voice has a unique, identifiable modulation — anyone who uses telephone banking will be familiar with speaking their password — so too does your biomechanical input.
When you type on a keyboard or a touchscreen, the force, speed, and accuracy with which you hit characters are dependent on two things: your cognitive process and the unique biomechanics of your hands (the bones, ligaments, and muscles).
For example, when I type WordPress, I almost always type it as WordPRess (with a capitalized R). That is one facet of my combined biomechanical and cognitive process.
KaST uses keyboards and touch screens to track combined biomechanical and cognitive patterns, identifying individual users based on their keystrokes.
KaST is heavily reliant on BMaC (Bio-Mechanical and Cognitive) input. Although Google hasn’t released any data to support the accuracy of KaST, BMaC is known to be surprisingly accurate.
Reports suggest that the KaST algorithm is 89.7% effective for character strings of 12 characters or more, leaping to 97.6% for 19 characters or more on a single device. That makes it too inaccurate for high-end processes like security but well within the necessary margin of error for a non-critical process like serving ads.
Google will be able to identify you on any machine, on any device, in any context, as soon as you type 19 characters or more
When switching to a touch-screen device, the accuracy plummets to just 87.8%. This may be one reason Google has been low-key in its trumpeting of the new technology so far.
According to TechBeat, initial trials of the tri-axis position of a device (X, Y, and Z rotation) were abandoned as inaccurate. Still, even without those additional tracking signals, Google claims KaST on mobile will achieve ~94% accuracy by the 1st quarter of 2022.
Much like many of the algorithms that govern our daily lives, KaST will be largely invisible to most of us. Unlike cookies that can be legislated for and removed from a local machine, your BMaC is as inescapable as your DNA.
Where privacy concerns really grow is that your BMaC follows you from device to device. How you type at home is identical to how you type at work. Your personal and professional profiles are now instantly connectable; Google will be able to identify you on any machine, on any device, in any context, as soon as you type 19 characters or more.
Within 24 hours of KaST’s announcement, Apple stores were reporting rush orders of pre-M1 MacBook Pros. With some stores reportedly selling out late on Wednesday.
The rush came in the wake of a Reddit post — that has since been removed — that claimed that the notoriously bad butterfly keyboard on pre-M1 MacBook Pros circumvented KaST because the inaccuracy of the keystrokes, and the tendency of the keys to stick introduced a random element that disguised the end-user from the KaST algorithm.
Although the Reddit post is unsubstantiated, it transpires that M1 Mac owners may not be the lucky ones after all.
Advocates maintain that KaST — and Google’s wider FLoC strategy — are beneficial to users and the web as a whole. They claim that identifying users without 3rd party cookies does more to protect privacy than hinder it.
Opponents argue that in a digital world rife with user tracking, privacy compromises of this magnitude cannot be contemplated simply to enable more sophisticated ad-serving.
Despite KaST’s early stages of development, privacy concerns are mounting, and a campaign has been launched to regulate Google’s use of the technology.

While APIs make it simple to share data back and forth between applications, the process of managing APIs can be anything but simple. A developer working with hundreds of different APIs over the course of their work can get bogged down trying to test, implement, and manage it all, turning what is supposed to be something straightforward into another layer of complexity.
Building API integrations is complex, but Postman makes it easy to create an API service. With Postman, developers can simplify every step of building and managing APIs — from development and testing to collaboration and support — so that more people can design APIs with simplicity, usability, and consistency.
So, really, you’re in the business of designing websites for your clients’ audiences.
But how do you ensure you get it right? You could take what your client tells you at face value, but that’s only going to scrape the surface of who their audience is.
What you need to do is figure out how consumers think and why they respond to websites the way they do. A lot of this is already explained to us by psychology principles.
Once you memorize them, you’ll be able to design user journeys that get visitors to respond exactly as you and your client want them to.
We as humans think certain ways, and your design should cater to those underlying thought processes and natural responses.
Below are 15 psychology principles that’ll help you design better, more intuitive digital experiences for your end-users:
The Aesthetics-Usability Effect suggests that people equate more attractive interfaces with more usable ones. In other words, a good, modern, responsive design should always be your starting point.
Color psychology tells us about color’s influence over how something is perceived. With color so strongly tied to emotion, you can do a lot to affect how visitors perceive a website and the brand behind it.
Just as a color has the ability to affect someone’s perception of a brand or the content they’re looking at, so too do individual shapes used within an interface. Each shape — circles, squares, triangles, hexagons, and polygons — has a unique psychological association.
Gestalt Principles are a way for humans to make sense of chaotic data presented to them. So, rather than see a bunch of text, images, and space, the human brain recognizes patterns to simplify complexity.
About half a dozen principles are associated with this theory, and they’re related to factors like symmetry, similarity, and proximity.
The Mere-Exposure Effect, or Familiarity Principle, suggests that people are more likely to prefer things that seem familiar.
Jakob’s Law applies this psychology specifically to the internet user experience. It suggests that users expect your website to work the same way as the other sites they spend their time on.
The Von Restorff Effect, or Isolation Effect, describes what happens when someone is exposed to identical stimuli, and then a unique element is introduced to the fold. It’s the outlier that will most effectively grab their attention.
Selective disregard is a type of “blindness” users develop to anything seemingly irrelevant to their main goal. This often occurs when a design or marketing trend grows stale — like websites that use the exact same cookie consent banner.
Hick’s Law states that the number of choices a person has to make will increase the amount of time it takes to make a decision.
This is a fundamental principle to pay attention to on ecommerce sites as you want to speed up the decision-making process, not slow it down.
Loss Aversion states that decision-making is more commonly driven by avoiding losses than acquiring gains.
If your website or the content within it gives visitors any reason not to trust it or feel confident in taking action, you’re more likely to see high abandonment rates than conversions.
The Paradox of Choice is a response to the problem posited by Hick’s Law. It suggests that the reduction of choices makes consumers feel less anxious, which, in turn, increases confidence and satisfaction with purchases.
If your site suffers from high cart abandonment or product returns, the paradox of choice would be a useful principle to leverage.
Miller’s Law, also referred to as Cognitive Load Theory, has to do with memory capacity. On average, people can only have about seven items stored in their working memory at any given time.
This psychology principle encourages the reduction of options and the general reduction of content to improve focus and decision-making capabilities.
Feedback is one of the principles of learning and plays a big part in interaction design.
Feedback is what designers use to tell people when they’ve made progress towards a goal or achieved it. You can also use it to teach visitors how a website will respond to their actions, which encourages faster and more confident engagements with your website.
There are two types of motivation. Intrinsic motivation is an internal one, whereas extrinsic is external.
It’s Extrinsic Motivation that plays a role in getting users to complete more tasks online. As a designer, you have to make sure these kinds of “rewards” are obvious.
Not so much a psychological principle as it is a psychological phenomenon, Social Proof or Influence, suggests that people will copy the actions of the masses. It also refers to the assumption that the truth lies with the majority.
This is why customer reviews, client testimonials, and user-generated content have become so useful on websites.
The Peak-End Rule states that people will judge an experience based on their very first and last impressions of it. This is somewhat related to the Serial Position Effect, whereby people will remember the first and last items in a group.
So, this is something to remember when you build out the top and bottom of each page as well as the start and expected end to the user journey.
Want to build better websites? Then, you need to design from the end users’ perspective.
The best place to start is with psychology principles, as they’ll tell you how most consumers think and what motivates them to respond. If you understand this inherent cause-and-effect relationship, you can design websites that elicit the right kind of response from your visitors.

We tend not to think about it, but the Internet has a physical dimension. It’s a complex network of wires, cables, servers, and technical odds and ends — if you really want to, you can track it down; doing so is particularly easy on small islands because there tends to be a single cable tethering the region to the wider world.
Those physical cables run all the way to your building, and although an ISP manages them, they are normally rented from public bodies as part of your national infrastructure.
Beyond the physical, international bodies govern protocols like ARP, IEEE, HTTP, NTP, FTP, and others, which control how data is transmitted through the network and keep everything playing nice.
Then, at the other end of the equation, there’s your device. It may be a phone, a tablet, a notebook, a desktop. It’s probably several of these. And because it’s your device, everything on it feels like yours. We tend to think of it as our method of accessing the Internet instead of being part of the Internet — in reality, it’s both.
On your device, the software you use to access the Internet is your browser. For 65% of people, that’s Chrome. Even if you’re reading this on Edge, it’s created with the Blink engine, an extension of Chromium, which is the basis for Chrome. In fact, almost every browser is built using a variation of Chromium, except those on Apple devices that require Apple’s own WebKit to be used instead.
Chromium is ostensibly open-source. WebKit is not, but both are geared towards their primary contributors’ business goals; neither Chromium nor WebKit will make a change that negatively impacts Alphabet or Apple.
Your browser is just a copy of a pre-compiled set of source files sat in a Git repo somewhere. You may have installed a few plugins in your browser. You may have bookmarked a few pages. You’ve probably moved it to your dock or your home screen. Those features are just nice add-ons for the GUI; what really matters is what decisions are made about how to render web technologies.
Imagine a world in which every single car used the same mid-range Ford engine. Add in a stereo, and paint it any color you like, you can even pick your own tires, but under the hood, it has to be that mid-range Ford engine. And the only justification is that it’s too much work to create an alternative.
The 2020s are going to be a time of enormous change. You can smell the panic in traditional banking sectors every time Cryptocurrency is mentioned. Real estate billionaires are desperately trying to get us back into offices we don’t want to return to. And yes, I’m sorry, but the climate crisis is looming, and it will force our hand. The values of a whole generation have been rapidly reassessed. Innovation and the potential for innovation are rife, except, ironically, on the Internet, where we’re still chugging away with the mid-range Ford engine under the hood.
The web has reached the point at which the browser engines we choose define real-world infrastructure. There’s a fork in the road: either browser engines are part of an infrastructure that should be rationalized into a single browser protocol, or alternative browser engines need to be nurtured, encouraged, and accessible by choice.

This tutorial shows how you can recover data from either a fat finger or malicious data attack. This tutorial can be utilized if the data issue is found within the Cockroach GC window for a particular zone configuration which by default is 25 hours. An additional tutorial will show how to recover using a backup.
For this example, we’ll create a MOVR workload and show how to recover from a malicious attack from a user called devil. On the MOVR rides table, let’s activate an audit log so we can see all of the SQL transactions that incur on the table. While the workload is running, we’ll inject the rogue user called devil and have that user create a malicious transaction that updates all of Tyler Dalton’s transactions to be $1000.

Levallois – 8 mars 2021 – SAP annonce son intention de parvenir à la neutralité carbone de ses activités d’ici la fin 2023, soit deux ans plus tôt que prévu. Cette annonce coïncide avec la publication du rapport intégré 2020 de SAP. L’année dernière, l’entreprise a plus qu’atteint son objectif de réduction d’émissions de gaz à effet de serre (GES) avec la mise en place de nouvelles façons de travailler et de voyager des 100 000 collaborateurs SAP, engendrées par la pandémie de la COVID-19.
La forte diminution des vols d’affaires a contribué de manière significative à la réduction de l’empreinte carbone de SAP en 2020. Les employés travaillant principalement à domicile, les émissions de carbone causées par les trajets quotidiens et l’exploitation des immeubles de bureaux ont diminué. En conséquence, SAP a pu dépasser de 43% son objectif de réduction des émissions nettes de carbone sur l’année 2020, en générant 135 kilotonnes (kt) au lieu des 238 kt prévues. À titre de comparaison, les émissions de SAP en 2019 étaient de 300 kt. En accélérant la mise en place d’opérations neutres en carbone, SAP anticipe l’évolution actuelle et confirme son rôle de pionnier dans la protection du climat.
En s’efforçant de devenir neutre en carbone, SAP prend en compte toutes ses émissions directes et indirectes, ainsi que certaines émissions provenant de la chaîne d’approvisionnement, notamment celles liées aux vols d’affaires, aux voyages d’affaires en voiture de location et aux datacenters de sociétés partenaires. L’entreprise utilise l’approche consistant à éviter, réduire et compenser les émissions. Dans la mesure du possible, SAP cherche à éviter la création de GES par diverses pratiques commerciales, telles que l’utilisation des technologies de télécommunication plutôt que les déplacements. Si les émissions ne peuvent être évitées, SAP exploite des innovations, telles que l’éclairage à faible consommation d’énergie dans les bureaux, les systèmes de refroidissement efficaces dans les datacenters et les solutions de mobilité alternatives. Enfin, SAP compense les émissions inévitables en soutenant des projets climatiques et en travaillant avec des partenaires qui respectent la norme de qualité avancée par la Fondation Gold Standard ou des normes de qualité équivalentes. En outre, SAP mène continuellement de nouvelles initiatives d’entreprise, comme l’application d’un tarif interne carbone sur les vols d’affaires.
Depuis 2017, SAP poursuit également un objectif climatique certifié par l’initiative Science Based Targets (SBTi) pour apporter sa propre contribution à la limitation du réchauffement climatique à 1,5°C au-dessus des niveaux préindustriels. Si son objectif « zéro carbone » s’applique principalement à ses propres activités, l’objectif climatique de SAP englobe également la chaîne de valeur en amont et en aval. Depuis 2014, SAP utilise 100% d’énergie renouvelable pour alimenter tous ses data centers. Grâce à son cloud vert, SAP peut proposer à ses clients des solutions de cloud computing neutres en carbone.
SAP apporte son soutien aux objectifs de développement durable fixés en 2015 par les Etats membres des Nations unies, en se concentrant particulièrement sur l’objectif 13, Action pour le climat. Ici, la plus grande force de SAP réside dans sa capacité à aider ses plus de 400 000 clients dans le monde à mettre en œuvre des mesures de protection du climat grâce à des offres telles que le programme Climate 21. Avec ses clients et partenaires, SAP fournira plus d’informations sur les solutions dans ce contexte ainsi que sur l’économie circulaire, le pilotage holistique et le reporting lors du SAP Sustainability Summit qui se tiendra virtuellement les 28 et 29 avril 2021.
