Suggested March 2024 Laptop Evolution: Snazzy And Sleek
SAN FRANCISCO (Reuters) – Say goodbye to the “black brick” laptop. The era of the plain, dowdy PC is officially over.
As computer makers roll out their new notebooks and netbooks ahead of the end-year holiday shopping season, razor-thin, sleek and colorful are most definitely in, as are arresting designs in an ever-expanding array of choices.
Hewlett-Packard Co and Dell Inc are now more likely to point to subtle etchings in the exterior shell, or a famous artist behind a new design, than to the “speeds and feeds” that PC makers used to tout when they wrestled for technological superiority.
It was only a few years ago that most laptops were some variation of a dull box that came in gray or black, with the exception of Apple Inc, which was making distinctive laptops back in the 1990s.
Now, design is permeating the PC market like never before as the increasing commoditization of machines leaves few major differentiators on performance, so a stylish case is one of the last remaining areas of competition.
Ed Boyd, vice president of design for consumer products at Dell, the world’s No. 2 PC maker, arrived at the company nearly two years ago from Nike Inc. He said the PC market is transforming in the way that athletic shoes did.
Nike “took a commoditized product — sneakers — and made it hip and cool and relevant,” he said. “What you’re witnessing is the same transformation in the PC business … this phenomenon is crossing both the enterprise and the consumer space”
As PCs have become ever more light and portable, consumers and businesses are placing a premium on the look of machines that are now more likely to travel out of the home or office.
And PC makers are using design to target different demographics, such as HP’s collaboration with fashion designer Vivienne Tam on netbooks aimed at fashion-forward women.
Stacy Wolff, director of notebook product design at HP, said the world’s largest maker of PCs took a “big gamble” when it began to focus on design in 2005 — one that he said has paid off. Prior to that, HP notebooks were essentially “technology in kind of a nondescript container,” he said.
Wolff said HP’s new focus was immediately evident in its income statement: “Once we made it a strategic element of any development, our financials have just skyrocketed.”
At the dawn of personal computing in the early 1980s, the first mobile PCs began to emerge from companies like Tandy, Osborne, NEC, Epson and others. Many of the early models resembled slabs of beige plastic, bulkier than desktops today.
The early 1990s saw the launch of Apple’s PowerBook line, which helped set the standard for design, along with IBM’s ThinkPad. Sony’s sleek Vaio notebooks followed later in the decade, along with Apple’s colorful iBook line.
But PCs 10 years ago were still largely seen as vessels for technology, rather than design or fashion statements.
Jeff Barney, general manager of Toshiba America’s digital products division, said the company introduced color in PCs earlier this decade, but they failed to catch on. “The consumer wasn’t ready for it,” he said. “We were just ahead of the trend.”
As components became cheaper and lighter, PC vendors found more room to explore their creative side, bringing in new materials and finishes, and paying closer attention to design details to catch the eye of buyers.
“We think that design is one of the key buying criteria in retail for laptops,” said Barney.
A PC buyer today can choose from a dizzying array of colors, textures and designs. “Personalization” is the order of the day. For example, Dell offers more than 200 exterior designs.
IDC analyst Richard Shim said the market began to shift around 2005 with lower PC prices. “Consumers started to become the overriding voice in the PC industry and what they were saying is: ‘Look there’s enough performance here for me to do what I need to do … but what I want is a PC that doesn’t look like everyone else’s,’” he said.
PC makers are first and foremost technology companies, he said, but they have realized that many buyers are more interested in what a notebook looks like than what’s inside. (Editing by Steve Orlofsky)

The genesis of species, as hypothesised by Darwin, sparked much debate. Darwin’s hypothesis lacks contemporary genetics and molecular biology concepts. He could not explain how characteristics emerge and persist in a population.Mendelian Genetics—Modern Evolutionary Theory
J. Gregor Mendel (1822-1884) researched the Inheritance of acquired traits, but it was not recognised until 1900. When Mendel’s work on “Inheritance of Acquired Characters” was found in 1900, the notion of evolutionary change was more grasped. Only after the rediscovery of Mendel’s ideas was the foundation of biological reproduction and heredity established. The field of genetics grew rapidly and explosively in the 1900s.Biochemical Genetics
The entire development of the chromosomal theory of inheritance unavoidably resulted in a better understanding of the role of genes as determinants of heritable features. This progress was greatly facilitated by linking genetics with another nascent discipline: biochemistry. Thus, biochemical genetics was created to understand gene functions in biochemical terms.
The most important contribution of the new discipline is, without a doubt, the one gene-one enzyme idea proposed by Beadle and Tatum based on their pioneering work with the bread mould Neurospora crassa. Because not all proteins are enzymes, this idea has been renamed the ‘one-gene-one-polypeptide’ theory. This topic has complexities that we cannot discuss here. However, a troubling implication is that the immediate phenotypic result of gene expression is a protein.
What should appeal to you right away, as flowing from the concept, is that just as anatomical and embryological relationships and differences have been exploited to document organic evolution and also erect phylogenetic trees, it should be possible to compare the structure of proteins – i.e. look at the ordering of their constituent amino acids-serving the same function in different organisms to seek evidence for their ‘evolution’. This has been a very active topic of study.Molecular Evolution
For one reason, studying the evolution of genes is not the same as studying the evolution of proteins. The rationale is straightforward. Proteins are the result of structural genes being expressed. Furthermore, structural genes represent a modest proportion of overall DNA content, particularly in higher species. Thus, studying the evolution of DNA sequences is a worthwhile endeavour in and of itself, and significant breakthroughs in our understanding of biological evolution have emerged from such research.The Chromosome Theory
Thomas Hunt Morgan (1866-11945) thought Darwin’s theory of natural selection was flawed because it was difficult for him to understand that extensive adaptations arose in an organism merely by accumulating minor random changes. Darwin offered no mechanism to explain the genesis or inheritance of variants. Morgan dismissed Mendel’s hypothesis as entirely speculative. He acknowledged that Mendel’s theory could explain and predict breeding outcomes, but Mendel could not explain the inheritance mechanism.
He contended that no one chromosome could be responsible for unique hereditary features. He conducted experiments on Drosophila and presented his renowned “Chromosome Theory of Heredity.” Morgan proposed the sex-limited (now termed sex-linked) theory based on his research on Drosophila. He claimed that females’ X-chromosomes carried these sex-limited characteristics, which held several separate heredity units. He referred to these units of inheritance as genes (the term gene was coined by Danish botanist Wilhelm Johannsen in 1909). He believes genes are connected in series on the chromosome and responsible for inherited features. Morgan was a pioneer in the study of genetics. Boveri-Sutton recognised chromosomes as the carriers of genetic material.Hugo De Vries’s Theory of Saltation
Hugo de Vries stated that natural selection is not required to emerge new species. He claims quick, extreme modifications can reorganise the whole genome, resulting in new phenotypes. These abrupt alterations were referred to as mutations or saltations by him. His mutation theory was based on multiple generations of studies on Evening Primrose (Oenothera lamarckiana).
He was amazed by the sudden development of seven new types of Evening Primrose in his garden, and he discovered that all of these varieties were heritable. He noticed that the unexpected appearance of new hereditary features in Evening Primrose offered no sign of their presence in earlier generations. He referred to these mutant Evening Primrose people as mutants and the rapid alterations as saltatory mutations.
Hugo de Vries defines mutations as “rapid, large heritable changes.” On the contrary, Darwin emphasised minor cumulative alterations. According to Hugo de-Vries, mutations are random and can arise in any direction. Mutations can occur in different individuals of the same species, giving rise to many new related species; they can be beneficial or destructive when exposed to natural selection, nature favours and selects favourable mutations while eliminating detrimental ones. (death of the mutants). Less damaging mutations, on the other hand, can survive in the progeny.
Though rare, mutations are widespread; mutations may accumulate in natural populations and contain enough genetic variety to develop fast when environmental conditions change. The mathematical theory of population genetics, established by Ronald A. Fisher and John B. S. Haldane in England and Sewall Wright in the United States, demonstrates that natural selection and mutation work together to promote adaptive evolution.Conclusion
Mendelian Genetics and Molecular Evolution are two important contributions to the field of genetics in the 1900s, with the one gene-one enzyme idea proposed by Beadle and Tatum being the most important. Morgan proposed the Chromosome Theory of Heredity, Boveri-Sutton recognised chromosomes as the carriers of genetic material, and Hugo de Vries proposed the Theory of Saltation. Mutations are rapid, large heritable changes that can be beneficial or destructive, and natural selection and mutation work together to promote adaptive evolution.
Various researches have revealed that whenever we hear an object, we retrieve it using an image from our brain. For instance, if I ask you “Do you like apples?” . You won’t think of the alphabets “a”, “p”, “p”,”l”,”e”, rather you will recall all relevant information regarding apple using the image of an apple. This is how possibly our data processing in our brain work. Of course it is complicated and highly efficient. Now if ask you “What is a database?”, you will mostly think of a collection of tables related to each other. If the same question was posed to a person in 1990s, possibly he would have only thought of a single big table from which they retrieve all the chúng tôi today we have really moved on from this simplistic definition of databases.
This article will help you understand what type of database exist in this industry currently. I also did an interesting exercise of plotting these database types in a tree structure with a time axis. This will help you visualize how database definition and application changed with time.Evolution of Database Management System
We are too used to timelines on Facebook. I thought it will be a good idea to start this article on a similar line. Following is a tree which will help you map all types of popular database management system in a timeline:
The timeline varies from 1980s to current date and is not exhaustive of all forms of data management systems. However, we will be able to cover most of the popular data management system.Flat File Database
This is probably the easiest to understand but at present rarely used. You can think of this as a single huge table. Such type of datasets were used long back in 1990s, when data was only used to retrieve information in case of concerns. Very primitive analytics were possible on these database.Relational Database
Hierarchical Database is very similar to your folder structure on the laptop. Every folder can contain sub-folder and each sub-folder can still hold more sub-folders. Finally in some folders we will store files. However, every child node (sub-folder) will have a single parent (folder or sub-folder). Finally, we can create a hierarchy of the dataset :
Hierarchical databases, however can solve many purposes, its applications are restricted to one-to-one mapping data structures. For example, it will work well if you are using this data structure to show job profile hierarchy in a corporate. But the structure will fail if the reporting becomes slightly more complicated and a single employee reports to many managers. Hence, people thought of database structures which can have different kinds of relations. This type of structure should allow one-to-many mapping. Such table came to be known as Relational database management system (RDBMS).
Following is an example RDBMS data structure :
As you see from the above diagram, there are multiple keys which can help us merge different data sets in this data base. This kind of data storage optimizes disc space occupied without compromising on data details. This is the data base which is generally used by the analytics industry. However, when the data looses a structure, such data base will be of no help.NoSQL Database
NoSQL is often known as “Not Only SQL”. When people realized that unstructured text carry tonnes of information which they are unable to mine using RDBMS, they started exploring ways to store such datasets. Anything which is not RDBMS today is loosely known as NoSQL. After social networks gained importance in the market, such database became common in the industry. Following is an example where it will become very difficult to store the data on RDBMS :
Facebook stores terabytes of additional data every day. Let’s try to imagine the structure in which this data can be structured :End Notes
Databases form the foundation of analytics industry. Even if we don’t know each one of them in detail, we should have an overview of the entire spectrum of databases. In this article we discussed the popular types of datasets and how the need of databases evolved with time. In the next article we will continue the same discussion and take it a step further by understanding types of NoSQL databases.

Ekster wasn’t on my radar until just about a month ago when I got to test out the company’s smart wallets and I’ve found myself very impressed with the design, build quality, and functionality of the offerings. Read on for our full review of Ekster’s smart wallets and what sets them apart from the rest of the market. And, yep, the company is also doing a Black Friday promotion with a 40% off deal.Materials and build quality
Ekster uses full-grain premium bull leather for all of its wallets. The company also uses a two-toned finish on its leathers “giving them a distinctive look and color that will endure as the wallet softens, bends and forms to the way it is used, whether in pocket, purse or hand.”
I tested out the Vachetta Parliament in Brescia Bronze and the Secretary Cardholder in Nappa Black. From the first time picking up the wallets, the attention to detail and premium construction and craftsmanship is immediately apparent.
As for the quick access mechanism in the Parliament wallets and Senate cardholders, it uses a clever mechanical trigger to pop the cards up (no batteries). As for how it keeps up to 6 cards secure without falling out, there is a rubber strip on the inside edge that with little nubs that creates a snug fit for your cards.
Ekster offers a one-year warranty on its products along with a 14-day return policy for a full refund or 60-days refund period for store credit.Chipolo solar-powered tracker card
A really thoughtful touch to make its wallets smart is integration with Chipolo tracker cards. But taking things a step further, the Ekster/Chipolo tracking cards recharge via solar. It’s roughly the thickness of two cards and can slide into any card slot.
Three hours of solar charging offers up to 2 months of use.
Ekster/Chipolo tracker card in the back slot of the Vachetta Parliament wallet
The Chipolo tracker card is the secret sauce that brings Siri/Siri Shortcuts functionality for keeping track of your wallet. The Chipolo iOS app is well done and you can even use the button on the tracker card to ping your iPhone or snap pictures as a remote shutter button.In use
The Parliament wallets pack so much storage and functionality into a wallet that’s just about 0.5-inch thick. So that paired with the soft, high-quality leather makes them a joy to use day in and day out.
So you’ve got the cardholder portion with room for 6 cards and the fantastic quick access mechanism, then on the inside, there are two more slots on the left-hand side. Also on the inside on top of the cardholder on the right, there’s a handy elastic strap to keep cash and other small items like coupons, etc. Finally, the back of the Parliament has another card slot/pocket.
Other aspects I really appreciate include the slim design but there always being room for a random receipt, cash, or other small items. And all of that can be stored without a bulky wallet.
For times when you’d like to keep things even slimmer, the Secretary Cardholder is a perfect choice, it offers four card slots and a center pocket/card slot for cash or other items. You can also keep the Chipolo tracker card in any of the slots.
Vachetta Parliament in Brescia Bronze on the left, Secretary Cardholder in Nappa Black on the right
Ekster also offers iPhone wallet cases and a few other related accessories like money clips.Conclusion
I honestly can’t think of any constructive criticism or ideas for how Ekster could make these products better. They’re really fantastic wallets and I highly recommend them.
I think for what you’re getting, they’re competitively priced but at the time of writing, Ekster is doing 40% off its wallets with the code “BF-40” at checkout making them an even more compelling value.
The Secretary Cardholder normally goes for $39, with the Parliament wallet starts from $79. The Chipolo solar-powered tracker card typically sells for $49.

The traditional content management system (CMS) is now frequently compared to headless CMS systems, as it gives enterprise marketers more freedom to deliver content faster through any digital channel or device.
A headless CMS is a content management system that decouples the backend infrastructure from the frontend presentation layer.
This allows developers to create digital experiences that are not limited by the capabilities of the CMS.
The headless CMS has picked up steam in the last year; many Fortune 500 companies have already adopted the technology.
Choosing the right system can be based on many factors, such as budget, type of business, needs, and deployment cases.
First, let’s take a step back and explore the core reasons why a CMS is so important.Content Management Systems (CMS)
In its most binary form, a CMS is software used to manage the creation and modification of digital content.
A CMS is often used for enterprise content management (ECM) and web content management (WCM). It usually has three main components: a content repository, a presentation layer, and a publishing workflow.
Content management systems are vital to the functioning of any website. They provide a clear structure for all your content, making it easy on visitors who might be looking for content via logical categories.
Put even more simply, a CMS typically provides two key features: a user interface for creating and editing content, and a set of tools for managing the content.
For example, a CMS might allow users to add new pages to a website or edit existing pages. Additionally, a CMS might provide features such as search engine optimization (SEO) tools to help improve the visibility of website content.
Many types of CMS software are available, ranging from simple systems installed on a single server to complex enterprise-level systems that support multiple users and sites.
When creating a website, many businesses find themselves in a catch-22 situation.
On the one hand, they want to make a sophisticated, feature-rich site that will wow potential customers and help them stand out from the competition.
But, on the other hand, they may not have the development resources on staff to build such a site from scratch.The Traditional CMS: Ease Of Use But Lack Of Flexibility
When it comes to choosing a CMS, ease of use is often a top priority for companies that don’t have dedicated development resources.
Traditional CMS platforms like Drupal offer a simple, website-based experience that is perfect for creating basic websites. WordPress offers a similar experience, though it goes beyond a traditional CMS; it is possible to go headless with WordPress.
A traditional CMS can create a simple, user-friendly website for many organizations without investing in costly development resources.
In addition, traditional CMS platforms are often quite intuitive and easy to use, even for those with limited technical expertise. As a result, they provide an ideal solution for businesses that want to create a basic website without breaking the bank.
Traditional CMS is a choice for many deployment types, such as:
If you’re looking to build your own personal website.
Setting up a small business.
You don’t need any kind of partnership beyond basic maintenance services from time to time.
A traditional CMS will set everything up quickly and allow you to manage sites through a single source interface. It can provide all necessary info about what goes where on each page while also offering essential SEO plugins.
Being monolithic for ease of use.
A vast array of templates and plugins, and content management tools.
A large community of users.Read More On SEJ Digital Evolution And Content Velocity
Modern-day enterprises have surpassed digital transformation – a word of old.
That transformation has happened across all industries.
Now digital and content marketers are in a race to evolve and stay ahead of the competition. To do that, they need to find efficiencies to help them utilize resources to work faster and smarter.
In today’s fast-paced business world, scalability is essential for success. Organizations must adapt quickly to agile workflows and processes as they digitally evolve.
They need to do this to meet the demands of their customers and stay ahead of their competition.
However, if you rely on developers to make changes to your system, this growth will be significantly hindered. In addition, as your company expands, you’ll also be at increased risk of security breaches and data loss.
This is where a traditional CMS can lack the infrastructure to keep pace with the ever-changing digital landscape and the velocity of content that needs to be produced almost instantaneously.
Pre-built templates may offer little room for creativity. For SEO pros and content producers alike, this can hinder your ability to rank content in search engines and drive traffic to your website.
However, a CMS is not a ranking factor.
In many ways, the monolithic nature of a traditional CMS compromises ease of use with a lack of flexibility.
For these and all the above reasons, many large enterprise organizations are shifting to modern content management systems that offer better scalability, security, and speed.Read More On SEJ The Headless CMS: Managing Multiple Content Channels
A headless CMS provides the same ease of use as a traditional CMS but with the added flexibility of modern API-based architecture.
This type of architecture makes it easy to integrate your CMS with other software applications and services, giving you the power to deliver better-structured content and create complex digital experiences.
Headless CMS decouples the backend infrastructure from the frontend presentation layer. This allows developers to create digital experiences that are not limited by the capabilities of the CMS.
One of the key benefits of a headless CMS is that it enables organizations to deliver content to any channel or device. For example, a headless CMS can be used to power a website, a mobile app, and even a smartwatch app.
That gives organizations the flexibility to meet the needs of their customers across a wide range of channels.
Another benefit of a headless CMS is that it makes it easier to manage and update content. With a traditional CMS, each time something is changed on the backend, it must also be updated on the front end.
That can be time-consuming and frustrating for users. With a headless CMS, however, updates can be made directly on the backend without affecting the frontend experience.
For example, your front end is your website, and the back end is your content repository.
If you are creating an article in your content stack with a traditional CMS, you must wait for developers to update the front-end website look before publishing.
With a headless CMS, content is separated from your tech stack, allowing editors to collaborate on publishing more quickly and faster.
A great use case for a headless CMS is for ecommerce and Omnichannel marketers who need to quickly create in-the-moment (relevant) experiences and produce content for multiple consumer touch-points – making it much easier for organizations to keep their content up-to-date.
A headless CMS is suitable for deployments where:
Speed is of importance, and bottlenecks are happening in development with marketing.
A large content depository is needed.
Omni-channel content is needed to be created and served with many CMS types.
Website experiences need to be fast, real-time, and responsive.
Enterprise security is a key priority.
Large sites (ecommerce) with lots of content need to be managed.Conclusion
Large enterprise organizations have many teams that they need to keep happy. In addition, they have many tools already working well in their tech stack.
Often, a traditional CMS can bundle together features that don’t need each other but add bloat to an application which can be difficult for developers. That’s especially true when creating or updating CMS.
In contrast, headless content management systems offer more speed and flexibility to deliver content across all the digital channels and new devices of today.
Choosing a CMS is a business decision that needs marketing, development, and IT input.
The solution you select depends on your type of business, the customers, and the audiences you want to serve content to.

You can’t focus on anything you’re working on with a noisy laptop fan. The culprit for a noisy laptop fan can be one of the two usually – dust and overheating. If you’ve been using your laptop fan for years now, you would probably wonder why there’s a humming sound that is a far cry from white noise. It isn’t helping you concentrate – you’re getting distracted, and that has to stop.
To get to the bottom of things, you must determine why your laptop fan is noisier than usual. The cooling fan running at a fast and non-stop rate could be blamed for this. It’s firing up or working harder than usual – churning like a wildcat – when it needs to get rid of heat or under an extreme workload. Even though your laptop is compact, it still is prone to the accumulation of dust. The clogged dust can wreak havoc on your laptop’s system, which causes it to run hot and noisy. The challenge here is how to cool down your laptop and zap the irritating noise.Fix Computer Overheating and Noisy Laptop Fan issues
If your Windows laptop fan makes weird grinding, buzzing or rattling noise when switched on, here are some ways to fix the noise and overheating Laptop fan issues.
Check the running processes
Close the processes
Use a laptop cooler
Clean your laptop fan
Repair or Replace the damaged laptop fan1] Check the running processes
When your laptop is noisy, it could mean only one thing – it’s overworked. Check on your processes and see if there are running applications or programs that are CPU-intensive or require your CPU to grind harder than usual. Check if there are processes that are close to running at 100% because it could be the culprit. If everything looks good, then it could be the CPU fan itself that needs further checking.2] Close the processes
Open your Task Manager and kill unwanted running processes to stop your CPU fan from buzzing or whirring up in an effort to keep up with the demands of running programs like when you’re playing games or watching videos online.

If all else fails, go right at the root of the problem. You can hire a professional to do the cleanup for you, or you can do this yourself. Dust and even hair could pile up and get clogged into your laptop fan which could reduce airflow. Cleaning it up would most likely solve your problem.
You need an air compressor and a small screwdriver to do this. Make sure that you take out the battery before you start cleaning to avoid static electricity. You should unplug the AC adapter as well. Unscrew the access panel to see the laptop fan. Blow out the dust using the air compressor. Make sure to do this outside of your home to avoid asthma or allergic reactions to dust.
Once you’re done, put everything back together and power up the system – you should have a quieter laptop now.5] Repair or Replace the damaged laptop fan
If your laptop fan is making strange rattling or buzzing noises, then that’s a problem, and the only fix is to repair or replace the fan altogether. This is caused by a broken bearing, and while the bearing can be fixed, it’s just a temporary fix that requires too much work in the first place. Your best bet is to acquire a replacement fan.
The laptop is considered to be the most popularly used device either or both for work and leisure. Many global businesses now operate with the use of the internet and with a laptop to keep things revved up. Cleaning up your laptop fan and making sure that it doesn’t overheat and will help you extend the lifespan and health of your laptop plus bringing down the noise to null.
