  • The Future of Mobile Applications: PWAs

    The Future of Mobile Applications: PWAs

    Today, I received an email from Google stating, “2 of your apps are affected by Google Play’s target API level requirements. We’ve detected that 2 of your apps are targeting an old version of Android.” Yes, I have created some mobile apps, and this email means that if your app was built for an older Android version, you must update it to support the latest one, or it will be removed from the Google Play Store.

    So, where is the problem, you might wonder? Well, I don’t even know where the app files are located on my hard drive. Let alone to open and search what to change, into the code, so it can support the latest API, etc. As a mobile developer, this is a common headache if you publish apps on app stores (Apple or Google).

    But there is another, less painful way to create apps that avoid these problems and run smoothly on almost any mobile phone and the web.

    The Future: Progressive Web Apps (PWAs)

    What are PWAs? They are essentially web applications (normal websites) that utilize some functionalities of mobile phones and can be used just like traditional mobile apps.

    Why are PWAs the future?

    1. Simplicity

    Traditional mobile apps need to be written separately for Android and iOS. Technically, you must write the app twice, once for each operating system (though some frameworks allow for cross-platform development, they still require tweaking for each OS). PWAs, on the other hand, are web applications written in JavaScript, HTML, and CSS—the heart and soul of every website.

    2. Cost Efficiency

    If your company needs cross-platform support plus web, you would need to hire multiple developers (or teams). With PWAs, one developer is sufficient to create the app for the web, significantly reducing costs.

    3. Maintenance

    Maintaining traditional apps is cumbersome. Each update requires submission to app stores, followed by a review process, leading to delays and additional costs. PWAs can be updated instantly without app store approvals. Changes made to the web application are reflected across all devices immediately.

    4. Independence from App Stores

    PWAs do not rely on app stores, meaning no ID checks, no cuts from in-app purchases, which means total freedom for developers. This autonomy is a significant advantage over traditional apps.

    The App Store Conundrum

    Why haven’t we heard more about PWAs?

    One word: Apple.

    Apple has a substantial influence on the market and technology decisions, especially in regions where it holds a significant market share (61% in the USA, over 45% in the UK). Apple’s App Store generates enormous revenue ($22 billion in 2022) by taking a 30% cut of transactions. Naturally, Apple has a interest in keeping users and developers within its ecosystem.

    While Safari, Apple’s web browser, does support PWAs to some extent, it lacks the full range of features and capabilities available in other browsers like Google Chrome. Apple has been slow to adopt advanced web technologies that power PWAs. Features like push notifications and background sync, crucial for a native app-like experience, are either limited or unavailable on iOS. This deliberate lag in support potentially steers developers back to traditional native app development.

    Embracing PWAs fully could undermine Apple’s revenue stream by enabling developers to bypass the App Store altogether.

    Conclusion

    Despite the obstacles posed by entities like Apple, the future of mobile applications is undeniably leaning towards PWAs. Their cross-platform compatibility, cost efficiency, simplified maintenance, and independence from app stores make PWAs an attractive option for developers and businesses alike.

    How to Install a Website as a Mobile App:

    1. Open the website you want in Safari (for iPhones) or Chrome (for Android phones).
    2. Click on the share button at the bottom of the browser.
    3. Press: Add to Home Screen.

    And that’s it. The website is now on your phone and can be used like any other mobile app. If the website supports real-time notifications, you will be able to receive them as well.

  • Stop paying for subscriptions

    Stop paying for subscriptions

    Do you remember the time when the internet was a free place? Information was there, and you just needed to use AltaVista or Yahoo to find it. There was Limewire, DC++ or Napster. There were free MP3s floating around the internet. There was MySpace!


    The programmes that we were using on the PC were “free” or almost free. At least there was no monthly subscription. Pay once, use it forever.


    But when MySpace disappeared and YouTube appeared, that’s when things started changing. Companies started charging for extra things and extra services. For example, Microsoft Excel was (and still is) a program that you can buy once. But fewer people buy it nowadays as a separate software. Most people use it as part of the Office suite that comes with Microsoft 365. AutoCAD, a very well-known CAD software, started the software-as-a-service charging model, without offering much of a service. What you would buy once and use forever, now became a quite expensive monthly subscription. And worth mentioning, “Photoshop” – the pioneering software for photo editing, the one and only go-to program that photographers use to edit their photos – went from a one-off program to a monthly subscription software. Music became the same way. Movies too.


    But things haven’t changed completely. There are still plenty and pretty good alternatives to the “I want you to pay us every month” model that the big players have adopted.


    LibreOffice: The open-source (and free) alternative to Microsoft Office. With this one, you can replace MS-Word, Excel, and many more. Find it here: https://www.libreoffice.org/

    Linux (Ubuntu): Microsoft Windows comes pre-installed on each laptop. But…their price is already included in the new laptop’s price tag. There are laptops out there without a pre-installed operating system that are significantly cheaper than the ones that have an OS installed. What you have to do is install a Linux distro such as Ubuntu, which is 100% free and easy to use. Especially if the computer is going to be used for online work, then why bother spending hundreds of pounds on an OS? Find it here: https://ubuntu.com/

    Affinity Photo/Designer: Adobe Photoshop and Illustrator are two well-known programs that photographers and designers use. About 10 years ago, they jumped to the subscription boat, and they are quite expensive, especially if you are not a professional designer/photographer. Thankfully, there are a dozen alternatives out there that aren’t following the monthly subscription model, and they are as good as Adobe’s programs (or even better). I am using Affinity’s Photo and Designer to do creative work, and I can say I am impressed. They work amazingly well on almost all platforms, even on iPad. Affinity sells them as a one-off payment/use forever product, and you can either buy them separately or as a package for all platforms (Windows, macOS, and iPadOS) at around £100. Get them here: https://affinity.serif.com/en-gb/


    ProgeCAD: The best AutoCAD alternative in the whole market. That’s it. It is a 100% AutoCAD clone (but the design engine is completely different), and it can do whatever a drafter that uses AutoCAD needs. I cannot recommend it enough! I really love this program. And not only this, it can read AutoLISP scripts that you might have! Find it at: https://www.progesoft.com/


    Stremio: An alternative to Netflix. The media center allows you to watch movies, series, YouTube channels instantly. You can watch in HD, with subtitles, and easily cast any file to TV through DLNA, Chromecast, or AppleTV! CAUTION: As it allows the user to use add-ons that have access to torrents, I would use it with a VPN, as this is considered piracy, which of course I condemn.


    Cloud storage: You can also set up your own online storage server and say goodbye to the expensive cloud storage from iDrive, Google Drive, Dropbox, etc. Although you have to buy and set up your own small file server, there are so many easy-to-use solutions out there that are user-friendly and can be set up in less than half an hour. I would recommend Synology (https://www.synology.com/en-uk) or Western Digital (https://www.westerndigital.com/solutions/network-attached-storage) because of their brands.


    One software at the time! Regain your freedom from the subscription model and control of your digital life. The options are hundreds.

  • Digitalisation of the construction industry

    Digitalisation of the construction industry

    We are living in the digital age. Everything nowadays is an app and the phones we have in our pockets are multiple times faster than the processor used to get the man to the moon. And yet, thousands of small/medium businesses haven’t jumped on the digital boat. Especially in the construction sector, pen and paper is still the king, even though COVID-19 gave a boost towards digital practices.

    There are several benefits into going digital but also there are some factors that for companies, especially small, are acting as blockers to the adoption. The negative factors include: the cost, effort and the changes needed. It is also worth mentioning that there is a shortage of skilled people that are equipped with the right digital capabilities to use new technologies.

    On the other hand, the benefits are countless. Just to mention a few:

    • Efficiency improvement: project management, project scheduling and communications can become more efficient, faster and reduce the project completion time.
    • Cost reduction: using software like BIM or CAD can help to avoid potential problems in the design, save costs on paperwork, printing and record keeping.
    • Better communication: Digital tools can enable better communication and collaboration among team members, subcontractors, and clients, leading to fewer misunderstandings and improved decision making.
    • Accuracy in data: Data are easier to access using specific software. Tools like Microsoft Excel can help with data analysis and keeping data up to date.
    • Remote working: The pandemic of 2019 showed that remote collaboration is achievable and, in many cases, can lead to even greater productivity between the team members, even if they are in different locations (even countries). This also leads to employee talented employees that would be difficult or impossible to employee before.
    • Reduced waste: Going digital can contribute to a reduced carbon footprint by omitting paperwork and physical folders and be replaced with digital storage and files.

    Simple digital tools and devices to make you become fully digital:

    • Storage Server

    First and foremost, going digital means you must have somewhere to store your files. Like old time folders and drawers, a server serves the same purpose. Of course, it takes way less space and money. There are 2 different ways to store files though. One is to hire cloud space or use services like DropBox, OneDrive etc. This is a solution that doesn’t require a physical server, but it adds on your monthly budget as it requires a subscription. The other solution is to buy a server.

    Server here, doesn’t mean the big chunky rack that will occupy a whole room. It is just a small device, or a computer (or in some cases a very small rack) that is 24/7 online. All of the office computers are connected to it and the files are accessible from all the connected devices that can see it as an additional Hard Drive.

    You can also add an additional remote server (somewhere far away from the first one, in another building probably) that will have the purpose of a backup machine. In case of a disaster there will be another exact copy of all your files somewhere.

    There are quite a few advantages using a server/cloud storage for your business:

    • There is a centralised file storage that can make it easier for employees to access the files they need.
    • It facilitates the collaboration between employees. Multiple employees can work on the same files from different locations.
    • It gives employees remote access to the files. Imagine being at the construction site and needing access to some drawings. You open a tablet, you go through the server, you open the drawings and voila! No need to carry any printed drawings with you.
    • It provides access to very old files that otherwise would be submerged under a pile of folders into a basement. You remember this old project back in 2018 near Exeter? You need to find your sign-off sheets from back then? No problem. Go through your server files and they will be there.
    • Microsoft Excel

    Excel is one of my favourite tools. Maybe it is my favourite, I don’t know. The one thing I know is that Excel has saved me thousands of working hours. It has helped me in calculations, in estimations, in tender preparation, in exporting hundreds of PDF files automatically. It is THE TOOL. It is a programming language wrapped around an understandable interface with understandable and easy commands.

    Excel can be helpful to construction companies in many ways. It can create and manage budgets, track expenses, create schedules, track progress, and identify potential problems, track inventory levels, order supplies and costs.

    It is used to create estimates for projects, track changes to estimates, and generate reports.

    It can be used to create and store documents, such as contracts, and invoices.

    I really don’t know why someone wouldn’t use it.

    If you are already using it check an article I have written back in 2019 regarding Excel commands that will make your life easier.

    • iPads (with a pen)

    When I bought my first iPad I wondered: “Why I haven’t bought one earlier?”. Yes, that was my reaction. I have written my review on my blog where you can read more about it. But how can it be used in the construction sector?

    As we are turning more of our processes into digital, the replacement of the physical paper is inevitable. We need something to depict the files we are using though. The mobile phone screens are too small. A laptop is too heavy. What a better replacement than an iPad? It has a large enough quality screen that can display drawings, photos and PDFs but it is not heavy and can be carried around. Add a digital pen to it and you have a killer combination for signing files, reading files and creating new ones. Give it access to your office server and you have your whole desk in a 10-inch computer machine!

    • AutoCAD

    AutoCAD is my second love (or first). I use it in combination with Excel in my everyday working tasks anyway. I could not live without it and despite that the software is around 40+ years, it is still irreplaceable.

    I use AutoCAD in all the take-offs I have to make in order to estimate budgets or quantities.

    Do you want to measure the volume of an excavation? AutoCAD is for you.

    Do you want to create a marked up drawing? AutoCAD will do this.

    Do you want to create a tender for a housing project? AutoCAD will help you with this as well.

    Do you want to draft a drawing of how your house’s front elevation will look like? AutoCAD…

    It is quite expensive though but there are lots of alternatives or clones out in the market.

    One of them is ProgeCAD. I discovered it in 2018 and I haven’t stopped using it since then.

    I wrote about my initial impressions on my personal block and you can read it here.

    • PDF Expert

    PDF Expert is a PDF editing app for iPhone, iPad, and Mac. It allows users to read, annotate, edit, and sign PDFs. PDF Expert also offers features such as OCR, form filling, and password protection. In my opinion is the best PDF tool on the app store but unfortunately it is only available for Apple devices.

    There are two reasons I like this app. First of all, it allows the user to annotate anywhere on a file. It means that you don’t have to use specific software to sign a document or to keep some notes on the PDFs. The second reason is that it has direct access to a WebDAV address. If you are using a server then it probably has the ability to provide access using various protocols (like FTP ie). One of them is WebDAV. I haven’t seen any other PDF tool using WebDAV protocol to be honest!

    • Project Managing tools (Trello etc)

    Project management tools are software applications that help project managers to plan, track, and manage projects.

    They can be used to improve the efficiency, productivity and profitability. They also help to improve the communication and the scheduling between different employees working on the same project.

    The most widely used software for Project Management are:

    • Microsoft Project: Microsoft Project is a popular project management tool that is used by businesses of all sizes. It offers a wide range of features, including scheduling, budgeting, and communication.
    • Trello: Trello is a visual project management tool that uses boards, lists, and cards to organize tasks. It is a popular choice for teams that need to collaborate on projects.
    • Monday.com: Monday.com is a flexible project management tool that can be customized to meet the specific needs of the organization. It offers a variety of features, including task management, scheduling, and reporting.
    • Wrike: Wrike is a cloud-based project management tool that is easy to use and affordable. It offers a variety of features, including task management, file sharing, and collaboration.

    I personally prefer using Trello and for smaller projects I also like KanbanFlow.

    • Communication apps

    Going digital means the meeting you would do face to face can be done online. Messages can be sent and received on various devices and files can be transmitted instantly with a press of a button.

    There are several communication apps on the market that can serve various needs.

    For normal messaging there are the classic apps like WhatApp, Signal, Viber etc.

    During the COVID-19 pandemic there was the boom of the online meeting apps. The usage of software like Zoom and Team skyrocketed.

    So which ones are the most popular?

    • Microsoft Teams: Microsoft Teams is a cloud-based collaboration platform that includes features for chat, video conferencing and file sharing. It is a popular choice for businesses of all sizes.
    • Zoom: Does the same as Microsoft Teams.
    • Google Workspace: Google Workspace is a suite of cloud-based productivity tools that includes Gmail, Docs, Sheets, Slides, and Calendar. It also offers features for chat, video conferencing, and file sharing. Google Workspace is a popular choice for businesses that need to collaborate on documents and spreadsheets.
    • Slack: Slack is a popular team messaging platform that allows real-time communication through channels, direct messaging, and integrations with various apps and services.

    I personally prefer Microsoft Teams. Not because is the best programme though, but because it is part of the Office365 suite.

    • Microsoft 365 Suite

    I assume that one way or another everyone uses some parts of the Microsoft 365 suite in their everyday work. Either, you login to your email account through Outlook, or you pay a monthly subscription for Excel then you are probably have access to the whole software package.

    The package includes so many programmes that can help you with productivity and digitalisation. Already mentioned, Teams and Excel are the ones that will help you a lot regarding productivity and admittedly, Outlook is a very nice email client.

    Other software included is the Microsoft Word (not much to explain here), Sharepoint, which can serve as a centralised document management and collaboration platform used for storing documents and allowing others to have access to them or create project specific sites and it also includes OneDrive which is cloud based storage.

    Overall, Microsoft 365 can improve the workflow of a business by improving collaboration, communication, file sharing and flexibility. It is definitely a must have.

    • Custom apps or specific apps for the sector

    Beside the above list, construction sector can benefit from various bespoke/sector specific apps.

    There are numerous platforms on the market that the user can build mobile/web apps with no code or low code (non or very little coding where the user uses a visual interface to build the apps by drag-n-drop).

    The most known are:

    The downside of those solutions is that the learning curve is quite steep and the monthly/yearly cost to use the platforms might be too high. The benefits of course are huge as you can build an app, that is not on the marker, as you want and make it do exactly what would help your workflow.

    On the contrary you can always hire an agency to code an application with normal code and databases that will run on a server. This is an even more costly solution but at the end you can have your own 100% bespoke app that can even scale.

    Finally, there are a handful of construction software on the market that might fit any purpose. To mention a few: COINS: an all-in-one ERP+ system that connects teams, devices, and all business processes on a single platform, On-screen Takeoff: a software that offers tools for estimating, managing bids and having project visibility, Bluebeam: a software application that allows users to markup, takeoff, organize, and collaborate with PDF files.

    Verdict

    The potential benefits in terms of efficiency, cost savings, communication, and environmental impact are undeniable. The digital era is here, and the construction sector should grab the opportunity to digitalise procedures in order to become more efficient and flexible. The benefits of going digital are numerous and compelling.

  • Things are changing. Constantly

    Things are changing. Constantly

    It has been 40 years since the first major breakthrough in construction software. It was 1982 and AutoCAD was first released. 1982 marks the beginning of construction innovation and automation.

    In the last 40 years lots of things changed.

    AutoCAD was only the beginning. Since then, we have seen the rise of the BIM software, structural calculation packages for complex construction calculations, estimating and project tracking packages and many more. And of course, the one and only Microsoft Excel that changed everything in the way we manage data. By the way, the first Excel version released in 1985.

    Even though it’s been 40 years of constant innovation, there are some sectors in the building industry that things haven’t changed much. Fieldwork has not experienced the same level of technological transformation as office-based tasks. The physical nature of the task, as well as the delayed acceptance of technology on construction sites, might explain part of the industry’s resistance to change.

    Take as an example scaffolding. In the office the workflow has changed. There are numerous software packages that can do structural calculation, can design scaffolds or manage a whole project, but on the field, the work pretty much remains the same (excluding some tools that are now working with batteries for example).

    The rise of AI

    The last decade we have seen huge steps done towards AI and automation. Especially, the last 3 years many AI products have made it to the market. Take a look at ChatGPT (the known AI chat machine) , Bard (Google’s AI chat), Stable Diffusion or Midjourney (two major tools for AI images). They didn’t even exist 5 years ago (or at least we didn’t know they existed) and now thousands of people rely their jobs on those tools.

    How this affects the construction

    Due to the complexity of the construction projects, AI is not as much of a threat to the construction (all levels) as it is to the humanity (as a whole). But, unless AI robots start designing and building other, more advanced robots (compared to them), construction is (almost) safe.

    But, there are some products that might replace some tradesmens’ work. Take a look at this robotic builder for example.

    4 days to build a 3-bedroom house. Not bad at all for the owner (that multiplies the profit margins) or the buyer that will buy a house cheaper. Bad news for the bricklayers though. Or the sculpturers (take a look at this  robotic sculpturer ).

    Even worse are the news for the setting out engineers. HP (Hewlett Packard) robots are already replacing their job.

    Things will just change.

    Even though automation is going to replace lots of humans there will be a huge shift in employment and new roles will be created. For example, the above “bricklaying” robot will need someone to feed it with material, check the setting out, feed it with designs etc. And, who you think will build those machines. The general idea that the west world has automated most of their production is of course false. The production has shifted to Asia, and it is coming to Europe/USA again.

    Conclusion?

    We are living in a very interesting era. The era that the new replaces the old, rapidly. Technologically, geopolitically, financially, and generally in every sector there are changes and transformations happening that will shape the future, which is unknown at the moment.

    From the perspective of the construction industry, innovation never stopped. Especially now automation at work is taking over every field and we should embrace this change. These technology innovations not only offer opportunities for cost-effectiveness and enhance efficiency, but also provide unreached levels of precision, safety, and sustainability in the construction industry.

  • Internet is dead(?)

    Internet is dead(?)

    Black mirror [1] prepared us for what would follow. And late 2022 was the beginning. Life won’t be the same from this point. Or it has changed a long time ago without us being able to realize it?

    It is November 2022 [2]. OpenAI introduces their new application called ChatGPT. The tech world, and not only, looks with eyes and mouth open without making any sound.

    Few months later, we read articles written by AI. We read about jobs that will disappear because of the AI. New applications published almost every day, that promise they will take advantage of the AI revolution and automate things to a point where people will have as little input as possible.

    Just a prompt. They are telling us that this will be the engineer of the future. Prompt Engineer. The guy with the best prompts gets the cash. And the world keeps moving.

    The dystopic future has become present. All our devices are not just for entertainment or communication. They have become advertising billboards. All our moves, thoughts and feelings are being analysed with the ultimate target: Buy more.

    Apple, decided to restrict the tracking on their devices and Facebook’s shares dropped like a rock from a cliff. What an amazing day it was [3]. But it’s just a drop of water into the ocean. An ocean of fake smiles, fake lips, and fake asses. Now, every barbie wants their lips to get infilled. At the gym training your butt to get Kardasian like results is the main target. Onlyfans promotes “women empowerment” (getting naked at the cost of a cheeseburger?). Instagram and TikTok has become the absolute space of super happy emptiness and the biggest ad-space so you will be tempted to buy stuff that you don’t want by people called “influencers”.

    When I first heard about the “Dead Internet Theory” [4] I laughed. Then I started thinking I was like: “Wtf, it might be true”. Or at least part of it. (The theory circulating around suggesting that internet is full of bots and AI is managing them since mid-2010s and a big chunk of your online interactions is not with real people but with bots, with the target to make you buy more products.)

    And then I started looking around. And I realised we are not alone on the internet. With us are our fake digital friends. Bots that keep us company. With some search there is a huge number of articles for Big Tech vs Bots. In 2018 YouTube axed millions of bots [5]. TikTok and Instagram still have a problem being full of bots and fake user [6], [7], [8], [9], [10]. Also, not to forget how Elon Musk tried to avoid buying Twitter. He brought up the bot problem [11] [12]. And then we have LinkedIn. The most gringe social network where people (or bots) are fake on almost everything, from articles written by AI to fake happiness posts, fake love and appreciation and even fake charities. [13] [14] [15] [16]

    And, like we did not have enough, we have fake music. Spotify recently removed tens of thousands AI generated songs. [17]

    All of these might seem disconnected. Everyone knows we have a bot problem. It’s going on for years. We got used to it. And on the other hand, we have AI. A fairly new addition to our digital life. But how those things connected? Well, they are. Microsoft has big stake into OpenAI (the company behind ChatGPT) and Bard is Google’s AI. Also, Microsoft owns LinkedIn and of course google is the mother of tracking user behaviour alongside with Facebook. Facebook also owns WhatsApp and Instagram. Now you can see the pieces of the puzzle. The biggest tech companies also own the best AI machines out there. And the main purpose is? Of course to create profit. Dystopian future doesn’t seme that far away anymore. Is it?

    But what will the future bring? I don’t think it will bring much, especially with inflation near 10% (or more), a war taking place and people demanding more war instead of peace, energy prices soaring while politicians blame the war for this, but they are the ones who created the energy crisis before the war started [18]. Generally, “Black Mirror” was a very good guide that should be taken into consideration when you are questioning how bright the future will be. I would suggest though, to meet more with real people, speak more and enjoy nature as much as you can. Scrap this virtual world and that rat race. Do things that you enjoy and fulfil you and don’t consume that much. You don’t need that new phone and this new pair of headphones. The old ones still work fine.

  • Cash is King

    Cash is King

    The current state of the UK’s market is not the best. Quite the opposite. With high inflation, interest rates up by 2% or more, high house prices and rents and unemployment at the very lows, it is the perfect mix of disaster.

    Possible scenarios to unfold

    Numerous economic events may occur in an economy with high inflation, low unemployment, high housing costs, and high interest rates. The precise result depends on several factors, including the general economic climate, governmental policies, and outside influences. Stagflation, asset bubbles, wealth redistribution, demand-pull inflation, wage-price spiral, and policy responses are a few examples of potential outcomes.

    Slow growth, high unemployment, and high inflation are the three conditions that lead to stagflation. This may occur if a central bank raises interest rates in an effort to curb inflation. This might result in lower consumer spending and investment, which would slow the economy. Asset bubbles develop when high home prices drive an unsustainable increase in asset values. If the bubble collapses, it may trigger financial instability and perhaps a recession. If most of the borrowers are low-income families, high interest rates might aggravate income inequality by causing wealth transfer. Demand-pull inflation, which occurs when rising demand for goods and services exceeds the economy’s capacity to meet them, can result from low unemployment and high inflation. This intensifies inflation.

    Wage-price spiral occurs when employees demand more pay to deal with rising costs, which forces firms to hike prices further to meet increased labour costs, which drives inflation further higher. Governments and central banks may adopt measures to solve these economic problems, such as raising interest rates or employing fiscal measures to stimulate the economy. How effective they are depends on various factors, including the current economic climate.

    Assets or cash?

    The money we have doesn’t purchase as much as it used to when the cost of necessities rises. Over time, having only cash might cause you to become less valuable. Owning items that can hold their value or rise in value despite price increases is preferable.

    When costs are high, people frequently make specific decisions to protect their money. One choice is to purchase government-issued special bonds that guard against rising costs. A different choice is to purchase real estate, such as homes or buildings, as its worth and the rent they may be rented for often rise with prices.

    Being a shareholder in a business can also provide you with protection because prices are frequently raised by businesses to increase profits. However, it’s crucial to invest in a variety of businesses because not all of them perform well when prices are high and the stock market is erratic. Some people also purchase valuable commodities like gold, silver, or other metals, which can maintain their value or increase in value during periods of high prices. Another choice is to use money from a cheaper country, although this comes with additional dangers, such as fluctuations in currency value or issues in the destination nation.

    Post-inflation

    In order to reduce inflation and stabilise the economy after significant inflation, central banks frequently adopt stricter monetary policies, such as increasing interest rates. As a result, the economy may expand more slowly, which might trigger a recession or a period of economic stagnation.

    Duration of the inflation before recession

    Large price increases can go on for a long period before a country’s economy dives into recession, but how long it takes depends on many factors, such as how big the price increase is, what the governments and banks that control money flow do, and the economy’s overall outlook. In general, there is not one rule that fits all situations. For example, the United States had a time of big price increase called “stagflation” in the 1970s and early 1980s, with slow growth, high price increase, and many people without jobs. Before the Bank of America increase the cost of borrowing, which decreased the prices but also made the economy nose dive in the early 1980s, this period lasted for almost ten years. Other times, those periods do not last long and might not make the economy go into a recession or stagflation if the policy makers act quickly. So, the periods of high inflation and high price increases last and how they are connected to a recession depend on special things about the economy, how well and how fast the government acts, and how strong the economy is itself. It also depends on other exogenic reasons like cost of imported goods, transportation and energy costs etc.

    Cash or assets in recession?

    Cash can be a desirable commodity to retain during a recession or period of economic stagnation because it offers protection, liquidity, and flexibility. With cash in hand, you can take advantage of investment possibilities, fulfil financial commitments, and preserve a safety net in case of unforeseen needs during such periods when asset prices may decrease.

    Why cash is king?

    Cash is king” is a saying that shows the importance of cash.

    When there’s uncertainty or the market is not steady, it is very important to hold cash or similar products, such as money market funds or short-term government bonds that can provide fast liquidity. Cash gives many options. First of all, money does not lose value in a recession. It is very important to have access to funds in case of sudden liquidity needs like paying bills, unexpected costs or investing. Have in mind that lots of companies are and will be in trouble not because they do not have assets or they are not profitable, but because they do not have access to cash when needed. Secondly, cash is considered safe because it will not lose value in hard economy times like stocks, bonds, or real estate that might do. Thirdly, having cash it provides the ability to manage your money and things you own. Cash lets you buy goods at lower prices when the market nosedives. Recession is the period that lots of investing opportunities arise. Even though “cash is king”, it is important to remember that spreading your money in different investments and keeping a strategy regarding your long-term money goals while mitigating risk is also important.  

    When the economy’s outlook is not good, having cash is helpful. One plan is to make sure you have emergency fund with enough money for 3-6 months living costs. This money should be accessible and used for unexpected expenses, job loss, or other bumps that may occur. Another plan is to use cash to pay debts with high interest, like credit card balances. This can put you in a better financial position and give more space for saving or investing.

    During hard economic times, you can use cash to invest in things that might be more valuable in the future. In those periods, prices of assets like stocks and real estate might go down, giving you a chance to buy at lower price. It also good idea to focus on safer investments, like high-quality bonds, stocks that give dividends, or stocks from industries that are not much affected by economic ups and downs.

    In general, be patient, keep your money and increase the savings, and when recession hits, be sure that lots of opportunities will appear.

  • Transforming the Economy and Shaping Our Future

    Transforming the Economy and Shaping Our Future

    Artificial Intelligence (AI) and tools like ChatGPT are shaking up the economy, bringing loads of potential to boost productivity and efficiency. But this revolution also raises questions about job losses, a growing social divide, and what work will look like in the future.

    AI is changing the game across industries, with tools like ChatGPT automating tasks like content creation, customer support, and data analysis. These advancements help workers build new skills, streamline their work, and increase their earnings. But this shift also brings challenges and concerns.

    Many people worry about job losses as AI takes over tasks once done by humans. While some jobs may disappear, AI can also open the door to new opportunities, like AI developers and data scientists. Plus, tools like ChatGPT can help workers focus on more meaningful tasks like problem-solving and strategic planning, which are harder to automate. This could lead to happier and more productive workers.

    But there’s another issue: a growing social gap between those who can use advanced tech and those who can’t. To tackle this problem, governments and organizations need to focus on digital literacy and make AI tech accessible to everyone. By encouraging ongoing learning and upskilling, we can help people adapt to a fast-changing tech landscape and ensure everyone benefits from the AI revolution.

    There’s a myth that technology has already automated most jobs, causing a decline in labor opportunities. But the truth is, many labor-intensive jobs have just moved to other continents, like Asia, due to lower labor costs. This highlights the complex relationship between technology, globalization, and economic forces. As tech continues to reshape the economy, it’s important to understand these dynamics and work towards a fair future for all workers.

    As AI and tools like ChatGPT change the way we work and live, we need to address concerns about job displacement and social divisions while recognizing their potential to create new opportunities, boost productivity, and enhance our quality of life. By promoting inclusivity, lifelong learning, and equal access to AI resources, we can make sure everyone shares in the benefits of this tech revolution.

    In today’s fast-paced world, it’s more important than ever for people to keep learning and adapting. Governments and organizations need to work together to support continuous learning and create a more inclusive, socially-focused economy. This means making education affordable and accessible, developing targeted skill programs, offering financial incentives, and promoting flexible work arrangements. Social policies that focus on reducing inequality and promoting social well-being can help bridge the gap between the rich and the poor, redistributing wealth more fairly, and providing universal social safety nets.

    In conclusion, promoting lifelong learning and adopting more social policies are critical for building an inclusive and sustainable economy in the face of rapid technological and economic changes. By focusing on everyone’s well-being and supporting accessible education, skill development, and work-life balance, we can ensure a brighter future for all.

    Lastly, making training data and models public is crucial for building trust and promoting innovation in AI. Open access to these resources lets researchers, developers, and the public better understand how AI systems work and hold them accountable. Collaboration leads to more innovative solutions and faster AI advancements. Plus, it helps the wider community identify and address potential biases and ethical concerns, ensuring AI systems are developed responsibly and fairly. In the end, it’s our data that AI systems are trained on, so transparency and collaboration are essential for creating systems that benefit everyone.

  • The eternal battle: iPhone vs Android

    The eternal battle: iPhone vs Android

    Over the last 4-5 years, I switched from Android to iOS. In the beginning, I had mixed feelings and, to be honest, I used to like Android so much that the iPhone didn’t feel that good. However, as I got used to it over the months and years, I recently got my second iPhone device and my feelings have reversed.

    That’s right, I got a second device in a span of almost 5 years. Would you do this with an Android phone? Probably not. You see, the problems with Android cannot be seen at first glance.

    The Android “ecosystem” has hundreds of devices to choose from, catering to all kinds of budgets and offering a feature variety that you won’t find anywhere else in tech. But there’s a big “but.” There are several reasons not to choose an Android phone if you’re concerned about quality and security.

    iPhones offer a consistent user experience as Apple designs both the hardware and software, which leads to a seamless and consistent interface across different models. iPhones receive regular software updates, including the latest features, performance improvements, and security patches. Apple supports its devices for several years, ensuring that even older models can benefit from new updates.

    With Android phones, you’ll be lucky if you get 2 years of security updates. The App Store also has a rigorous review process, which often results in a higher standard of quality for apps compared to the more open Google Play Store.

    In terms of connectivity and ecosystem, iPhones work well with other Apple devices, such as Macs, iPads, and Apple Watches, making for a more seamless ecosystem if you own multiple Apple products. On the other hand, despite some progress made by Android devices with Windows PCs and laptops, they still lag behind in making users’ lives easier.

    Consider how easy it is to change an iPhone device and move to a different one. You simply follow some steps on your phone’s screen, and within 20-30 minutes, all your data and apps are migrated to the new device. This will not happen with an Android phone unless it’s a Xiaomi and you’re migrating to a new Xiaomi or a Samsung, but I’m not sure this process is as smooth as iOS, and I’m pretty sure you cannot do this between different branded phones.

    Considering selling your iPhone? iPhones typically maintain a higher resale value compared to Android devices, which can be an advantage if you plan to upgrade your phone in the future. Apple is known for its focus on user privacy and security, implementing measures to protect user data, including encryption and strict app permissions.

    When it comes to personal data security, iPhones tend to offer better overall security for personal data, mainly due to Apple’s closed ecosystem and tight control over hardware and software. This makes it more challenging for hackers to find and exploit vulnerabilities. Apple provides timely software updates, including security patches, and the App Store has a more stringent app review process than the Google Play Store. Apple uses encryption to protect user data both at rest and in transit, and iPhones come with various built-in security features, such as Face ID, Touch ID, and Secure Enclave.

    Moreover, let’s not forget Google. Google is primarily an ad company, which means it collects your data for profit. The experience comes second or third. Sandboxing works well on both operating systems, but Google apps, especially Google Play Services, monitor every interaction you have on or near your phone and sell that data.

    Imagine this scenario: You are considering renewing your car’s insurance for another year, but it comes 20% more expensive than last year’s insurance. You wonder why. Meanwhile, you had been searching on your phone, through the Google search bar, for a pair of prescription glasses because you developed a bit of nearsightedness. While you normally wouldn’t even think about it, somehow the insurance company got “notified” about it and voilà! While Apple collects personal data, they confirm that they will never sell it. But, it’s up to the user if they trust them or not. Personally, after the “throttling-gate” was exposed, I tend not to trust them so much, but for now, I believe them as I’m pretty sure they don’t want to lose more money in the courts. Another alternative would be GrapheneOS, which is based on Android. I tried it for a month. Good luck with that.

    As for the devices’ costs, a mid-range Android device costs more than £200. Those devices tend to last for 2 years on average, so it’s £100/year for a phone. iPhone prices start from £600, but a device can last for 5-6 years with constant updates. It comes slightly more expensive than the £200 mid-range Android, but the quality is not comparable.

    That said, in the end, it’s up to the user’s priorities and preferences. Android is offered in a wide range of devices for every budget and need, while iPhones are more premium. Androids are more customizable, and the user can experiment with custom ROMs, while iPhones are locked. If someone is concerned about privacy and security, I would recommend iOS more. If those are not a concern and the budget is the priority, then Androids are very good devices. Also, Samsung and some Chinese brands like Oppo have made huge strides to offer state-of-the-art devices and designs like flip phones that cannot be found in Apple’s device family. Those devices might cost more than Apple’s Pro models, but they offer an experience that the user hasn’t had before. At the very end, it’s all about personal preference.

    What is Atob()

    atob is a JavaScript function that stands for “ASCII to binary”. It’s used to convert a base64-encoded string into its original binary data.

    Base64 is a way of encoding binary data (such as images, audio, or PDFs) into ASCII characters, so that it can be easily transported over a network or stored as text. This is useful because some systems can’t handle binary data directly, and text can be stored and transmitted much more easily. When the data needs to be used again, the reverse process of converting the base64 text back into binary data is performed.

    Tell me a bit about the AI history.

    The history of AI can be traced back to the 1950s, when computer scientists and mathematicians first began to explore the idea of creating machines that could simulate human intelligence. One of the earliest pioneers in the field was Isaac Asimov, a science fiction author who wrote extensively about the potential of AI in his books. He introduced the concept of the “Three Laws of Robotics” which were designed to ensure the safe and responsible use of AI.

    Print PDFs (multiple) from Excel with a press of a button

    On a previous article, dated 2 years ago, I explained how to automatically print to pdf a sheet, with a press of a button.

    This one is the part 2. It is a tutorial of “how to print multiple pdf files from populated tables” in excel, with the help of VBA.

    I wrote the code in 2018 and since then it has saved me (or the company I work for) a massive number of working hours (or weeks to be more precise).
