Celebrating the 30th Anniversary of Delphi version 1.0's Launch

Celebrating the 30th Anniversary of Delphi version 1.0’s Launch

Posted on by davidi

By David Intersimone “David I” – Friday, February 14, 2025

Today we celebrate the 30th anniversary of the launch of Delphi version 1.0 on Valentine’s Day, February 14, 1995, at the Software Development West Conference in San Francisco California. More that 12 years of continuous IDE, language, tools and library development led up to the launch of Delphi version 1.0.

The development of Delphi can trace some of its roots and technologies across Borland product releases including Turbo Pascal 1 (DOS and CP/M), Turbo Pascal 3 (overlays), Turbo Pascal 4 (units), Turbo Pascal 5 (integrated and standalone debugger), Turbo Pascal 5.5 (objects), Turbo Pascal for the Mac, Turbo Pascal for Windows, Borland Pascal 7 for DOS and Windows, Paradox, dBase and InterBase. While Borland Pascal 7 was available, the development team had been working for about 2 years to complete the first Delphi release (see links at the end of this article for a few of the important historical documents).

The Delphi “Sneak Peak” at the Borland Conference 1994

The first public showing of Delphi took place at the Borland International Conference (BIC) 1994 Walt Disney World Dolphin and Swan Hotels, Orlando Florida. The original language track was focused on Borland C++ 4 and also Borland Pascal. Paul Gross gave the “Product Address: Languages” in the Swan Ballroom on Monday morning from 8-9:15am. Prior to the conference a last minute decision was made to add two Delphi sessions: “Sneak Peak: Rapid Application Development in Pascal” session given by Zack Urlocker (Delphi95) and Bill Dunlap’s sneak session, “Sneak Peak: Exception Handling in Pascal”. “Even Spencer the Cat hasn’t seen this,” said senior product manager Zack Urlocker. Delphi95 will “compete with Visual Basic on the low end and PowerBuilder on the high end.”

It’s funny to look back and remember that the title of the Zack and Bill sessions were titled “Sneak Peak” – instead of “Sneak Peek” – a purposeful choice of the word “Peak” to denote the state-of-the-art technologies in Rapid Application Development (Visual Basic and PowerBuilder still did not integrate native code compilers).

There was also an NDA session for leading Paradox developer partners where Delphi95 was presented. One of the questions during the session was “is this the Paradox compiler that was rumored to be in development?” The answer was no, unless you wanted to use Delphi and the BDE to access your Paradox files.

The Delphi v1 Launch – Valentine’s Day, February 14, 1995

The Delphi launch took place at the Miller Freeman Software Development Conference West in San Francisco California, on Valentine’s Day, February 14th 1995 at 7PM just after Philippe Kahn’s keynote “The Importance of Object Computing – The Algorithmic Link”. Two editions of Delphi were announced: Delphi and Delphi Client/Server. Before the launch, we were demonstrating existing Borland language products in the Borland booth. The day after the launch we demoed Delphi to overflowing crowds of enthusiastic developers.

While we annually celebrate the launch of Delphi version 1.0 on February 14, the actual RTM (release to manufacturing) date, and the date that all of the Delphi v1 files are date stamped, was February 15, 1995. Gary Whizin, R&D manager for Delphi tells the story about the RTM date in a 10 year remembrance audio interview. Gary said that the team did sign off the Delphi 1 master on February 14, 1995 before driving to the conference for the product launch. A stop ship bug was found and the product was re-mastered and the team signed off the first version again on February 15, 1995 (the date stamp on the files).

What Made Delphi version 1 So Special

While Microsoft had Visual Basic and PowerSoft had PowerBuilder, what differentiated Delphi was the combination of the power of the Object Pascal language, a visual component-based development environment and desktop and SQL database access:

  • High speed, native code compiler
  • IDE providing visual two-way tools – form designer and source code editor
  • TObject, records, component, and owner memory management
  • Property Method Event (PME)
  • Visual Component Library (VCL)
  • Runtime Library (RTL)
  • Structured exception handling
  • Data-aware components live at design time
  • Database support via BDE and SQL Links


Running Delphi v1 on Windows 3.1 in a DOSBox on a Win10 (or 11) PC

To Get Started

If you’re unfamiliar with how to install and run Delphi v1 on Windows 3.1, watch the YouTube video, “Stu’s Game Reviews – How to Play Windows 3.1 Games in Windows 11!!! New for 2024!!!”. Sure, it’s about installing Windows 3.1 and running games, but the information and steps work for any Windows 3.1 software including Delphi v1. Hint: you don’t need to install the drivers mentioned in the video unless you also want to play games. https://www.youtube.com/watch?v=P4vtHkan5xw

The Software You Need to Run Delphi v1 on Windows 3.1

The following is a list of the required software to get Windows 3.1 and Delphi running on your Windows 10 (or 11) PC.

DOSBox-X: https://dosbox-x.com/ or DosBox v7.4.2 https://www.dosbox.com/download.php?main=1

Windows 3.1 (Retail) (3.5-1.44mb) Contains 1.44mb 3.5″ retail disk images https://winworldpc.com/download/41574932-18c3-9a11-c3a4-e284a2c3a570

Borland Delphi 1.00 (2-15-1995)(CD) ISO https://winworldpc.com/download/c2b3c3be-c38a-e280-b00b-c38711c3a5ef

Borland Delphi 1.00 (2-15-1995)(CD).7z contains the following folders:

Installing Windows 3.1 and Delphi v1

To install Windows 3.1 and Delphi v1 I used DOSBox-X because it has a feature to easily handle swapping the Windows 3.1 six floppy disk image files and because “Stu” told me to use it 🙂

Install DOSBox-X and choose a folder on your Windows 10 (or 11) PC hard drive. Select all of the default settings during the install.

To install Windows 3.1, start DOSBox-X and mount the floppy disk image files for Windows 3.1. (note: I put the Win31 floppy disk images on my hard disk in a folder named “c:\w31”. I installed Windows 3.1 in my c:\DOSBox folder). The commands I typed were:

  • mount c: c:\DOSBox
  • imgmount a: c:\w31\disk01.img c:\w31\disk02.img c:\w31\disk03.img c:\w31\disk04.img c:\w31\disk05.img c:\w31\disk06.img -t floppy
  • a:
  • setup

When Windows setup asks you to put disk 2 in drive A:, use the DOSBox-X menu “Drive” menu item, select drive A and in the popup menu select “Swap disk” (note: Guy said you might be able to use CTRL-F4). This will “put floppy disk 2 into drive A”. To complete the Windows 3.1 install, repeat this procedure for each of the remaining floppy disks. Note that DOSBox-X is in control of your mouse. When the Windows install asks for input (for example when it asks you to type in your name and company), hit CTRL-F10 to switch mouse control to the program your installing and then to get mouse control back to DOSBox-X hit CTRL-F10 again (you will hear an audible beep each time you hit CTRL-F10 if your PC’s sound is turned on).

When you choose to exit the Windows 3.1 setup program click the “Reboot” button to restart the DOS virtual machine to take you back to DOSBox-X.

To install Delphi v1 I put the CDROM install image, Delphi.iso, in my c:\installs folder. Using DOSBox-X, I typed the following commands:

  • imgmount d: C:\Installs\Delphi.iso -t cdrom
  • c:
  • cd windows
  • win

After Windows 3.1 starts, use the “File Manager” app to install Delphi.


and click on the “d” drive that contains the Delphi 1 CDROM.


Open the “INSTALL” folder and you’ll see folders containing the contents for each of the 15 floppy disk images (DISK1-DISK15) and the SETUP.EXE program.

Click on the SETUP.EXE program to install Delphi 1. Note: if you have the separate floppy disk image files (not recommended), follow the Windows 3.1 DOSBox-X “imgmount” command and floppy swap disk steps above for selecting and using all 15 of the floppy disk image files.

After Windows 3.1 and Delphi v1 were installed, the following is the c:\DOSBox folder contents:

With Windows 3.1 and Delphi v1 installed you’re now ready to experience the intoxication of using Delphi version 1.0 on your Windows PC 🙂

Running Delphi version 1.0

To run the Windows and Delphi you just installed, you can use either DOSBox-X or DOSBox.

Type the following commands:

  • mount c: c:\DOSBox
  • cd windows
  • win

Then from within Windows open the Delphi folder and click on the Delphi icon. Note: use Ctrl-F10 to capture and release the mouse for use on your PC desktop and in the DOSBox running Windows.

In the Delphi v1 IDE select the Help | About menu item.

Hold down the Alt-key and type (all caps) DEVELOPERS

Hold down the Alt-key and type (all caps) AND

You’ll see a picture of Anders Hejlsberg floating in one of the lakes on the Borland campus in Scotts Valley, California. I shot a video of Anders (in Denmark Donald Duck is called “ANDERS AND”), during an all day party to celebrate his engagement, and grabbed a video frame to put in the About Box for Delphi.

Hold down the Alt-key and type (all caps) TEAM

You’ll see multiple pages of the names of the extended Delphi team that were a part of the development, launch and support of Delphi 1.0 (in alphabetical order by first name).

Here is a group photo of the extended Delphi team taken in the outdoor amphitheater on the campus.


Three Delphi adds that appeared in developer magazines during the launch year

Happy 30th Anniversary Delphi Launch Day!!!

I send big hugs and love to all of the employees who ever worked on Delphi. I send my thanks to all of the technology partners and MVPs who support Delphi. And, I send my deepest thanks to all of the customers who have ever used Delphi (many still do), attend Delphi conferences and seminars, participate in Delphi user groups, participate in online webinars, and share knowledge, source code and suggestions to help everyone (including me) become better Delphi software engineers.

Check out my YouTube video: Windows 3.1 and Delphi version 1.0 running on my Windows 10 PC

I can’t finish this Delphi anniversary story without including a special developer, author and educator in my life, my brother separated at birth, and my technology travelling companion. That very special someone is Charlie Calvert. Charlie started at Borland working in technical support. Charlie is the author of “Turbo Pascal Programming 101”. After getting to know Charlie, I knew he was a one-of-a-kind developer, author and human being. I asked Charlie to join me in Borland Developer Relations. During the development of Delphi we knew that we would need great documentation, example programs, and to rev up our global Turbo Pascal community to be ready for the launch of Delphi. Charlie used his unique talents as a developer and an author to create his “Delphi Unleashed” book and also helped the team with the documentation. Charlie and I traveled the world together to present Delphi to customers, at conferences and meet with partners. While we were both children of the 60’s wearing comfy clothes (I wear Tie-dye t-shirts almost every day), on a trip to Madrid Spain we met with the government technology team working to create Spain’s early eBanking infrastructure. Nestor Miranda, head of the Borland office in Madrid, asked us to wear suits for the meeting because we were going to meet the head of the Bank of Spain. Along with two of Charlie’s programming books here is, probably the only time, a picture of Charlie and me at our hotel before we left for the meeting.

While I don’t travel, write, present and program nearly as much as I did during my 30+ years at Borland International, Inprise, Borland Software, CodeGear and Embarcadero, I have the code, pictures, videos and great memories that keep me smiling. I still program using Delphi as a semi-retired software engineer. Programming keeps me young, happy and alive!

How to Convert a PDF to PNG or JPG in Java

This article reviews three Conversion APIs that will allow you to convert any PDF document into an image. This includes conversion to a PNG or JPG array with one image created per page in your document. The article also discusses how you can merge and stack your PDF pages for conversion into a single PNG, or “tall” image. The goal for this tutorial is to simplify and improve your versatility for document display and sharing. Furthermore, as most documents can be converted to PDF, you can apply these APIs to any file, post-PDF-conversion. Read the DZone article.

Popular JavaScript Frameworks to Build API and Microservices

This Dzone post discusses the most popular JavaScript frameworks used to build APIs and Microservices. Microservices and APIs are often being confused for each other. In reality, they are 2 separate concepts altogether, where API is a communication pattern and microservices are an architectural pattern. Read the DZone article.

How to Build Real-Time Notification Service Using Server-Sent Events (SSE)

Most of the communication on the Internet comes directly from the clients to the servers. The client usually sends a request, and the server responds to that request. There are some scenarios in which the server needs to send a message to the client without the preceding request. In such cases, developers have a couple of options: use short and long polling, webhooks, websockets, or event streaming platforms like Kafka. However, there is another technology, not popularized enough, which in many cases, is just perfect for the job. This technology is the Server-Sent Events (SSE) standard. Read the DZone article.

Facebook Announces Beta Messenger API Support for Instagram

Building a C++ VCL Customer/Sales Master/Detail/Charting Application with 1 Line of Code

These days low-code development is en vogue. Various research groups, such as Gartner, put the low-code application development platform market at ~$10M billion in 2019 and project CAGR to be greater than 20% from 2020 to 2027. This post shows how you can build a Windows C++ Customer/Sales, Master/Detail/Charting application that only needs 1 line of code.

Things to consider when running visual tests in CI/CD pipelines

This blog post contains a summary of the author’s recent webinar and focuses on demos that show how to handle visual testing in CI/CD. The demos focused on 3 different CI/CD scenarios: Azure DevOps, GitHub Actions and Container Based Pipelines.

An Open Source Sorting Algorithms Visualizer

This GitHub project is a tool, made with python and pygame, for visualizing sorting algorithms in an educational way. The project’s purpose is to portray several sorting algorithms so the user can understand how a computer “move some pieces” to achieve the goal of having sorted data at the end!

A faster way to prototype your APIs using OpenAPI 3 and Swagger UI

The goal of this GitHub project is to create a generator that conveniently creates API definitions in the OpenAPI 3 format using marshmallow classes and saves them into a YAML file. You can think this project as programmable API definitions/documentation for your API (your API can be written in any language, not only in Python). Python is used here just for convenience of describing classes and has less code yet strong typing. Then you can inject the generated YAML file with Swagger UI to any project (just a page that renders Swagger UI HTML code which requests the generated YAML file).

Fun With SQL Using Postgres and Azure Data Studio

Azure Data Studio is a cross-platform database tool for data professionals using the Microsoft family of on-premises and cloud data platforms on Windows, macOS, and Linux. It is very easy to install and offers a modern editor experience with IntelliSense, code snippets, source control integration, and an integrated terminal. It’s engineered with the data platform user in mind, with the built-in charting of query result sets and customizable dashboards. You can learn more about it from the official website on this link. ADS also has notebooks that are similar to Jupiter notebooks for python and other languages and are great for combining formatted text with code. You can execute queries via a query window or via a notebook window. This post discusses some of the basics and at the same time shares the author’s experience using Azure Data Studio.

AppSec vs. DevSecOps, and what that means for developers

Traditional application security is different in two key ways from what has come to be known as DevSecOps. First, modern software companies are integrating application security into their DevOps pipelines, so security becomes part of the flow. Second, it’s also about DevOps being built into application security. In this SD Times article, Patrick Carey, who leads product strategy in the Software Integrity Group at security solutions provider Synopsys, explains these differences. By building application security into your automated development environment, he said, security “is initiated through events, rather than necessarily a phase where somebody at the end of the line, whose job it is to make sure that you didn’t screw up and code a vulnerability,” does the testing. On the other side of that coin, building DevOps into AppSec, eliminates the gates created by traditional DAST or pen-testing tools, creating instead guardrails that allow the team to move forward with relatively low friction but to stay on track. In the traditional gated pass-fail system, “if you fail you got your vulnerability report that just said you know there were a bunch of vulnerabilities, but oh, by the way we can’t tell you exactly where those are in your code; your developer’s going to have to go figure that out.”

5 edge computing predictions for 2021

The new business models that will push edge computing “from science project to real value” in 2021 are largely based around two factors, Forrester said: Cloud platforms having to compete with artificial intelligence, and the widespread proliferation of 5G will make edge use cases more practical. With those two drivers in mind, Forrester made five predictions about how the tech world will evolve in 2021 that will directly impact edge computing.

Looking for the Next Step in Cloud Performance? Look to Data Center Design

In the near future, data centers will need specialized storage and compute areas that are segregated from each other. For example, when designing a floor plan, it’s likely we’ll see data center operators walling off Compute-as-a-Service from Storage-as-a-Service. This can help solve issues around cooling, which is paramount to eliminating waste and improving performance. However, it doesn’t fully solve the issue of accessibility and latency speeds.

Product Demo Sucks Because It’s Focused on Your Product

In this exclusive interview, Falcone shares the structure of a winning product demo and the tactics he’s discovered to convince people that they need your product in just one conversation. one of the easiest and biggest mistakes he sees is that companies don’t effectively craft their demo to fit their specific audience — i.e. they don’t distill their dozens of features and selling points into the few that will really resonate with this particular investor, prospect, or even prospective employee.

PostMan’s 2020 State of the API Report

Every year, Postman surveys industry members to get a picture of the API industry—to understand who is working with APIs, how they are getting their work done, and where they see the industry going. More than 13,500 developers, testers, executives, and others took our 2020 survey and provided insights on everything from how they spend their time to what they see as the biggest issues and opportunities for APIs. Three key findings: API investments stay strong, The pandemic has changed the world, but it didn’t stop APIs, and APIs are the nucleus of digital transformation.

Hybrid cloud is where the action is

Multicloud is definitely a thing. However, it’s not exactly clear what that “thing” is. According to new survey data from database vendor MariaDB, 71% of survey respondents report running databases on at least two different cloud providers today. Yet when asked what would keep them from going all in on a cloud database, a vendor’s “lack of a multicloud offering” ranked dead last. In other words, everyone is doing multicloud, but no one knows why. Read Matt Assay’s InfoWorld article.

Nvidia claims Cambridge-1 is the U.K.’s fastest supercomputer

Cambridge-1, which Nvidia expects to come online by year-end 2020, is a joint project between GSK, AstraZeneca, Guy’s and St Thomas’ NHS Foundation Trust, King’s College London, and Oxford Nanopore. Built on Nvidia’s DGX SuperPOD architecture, it’s anticipated to deliver over 400 petaflops of AI performance and 8 petaflops of Linpack performance. That would rank it 29th on the TOP500 list of the world’s most powerful supercomputers and among the top three most-energy-efficient machines in the Green500. Read Kyle Wiggers’ VentureBeat article.

Survey finds cloud complexity increases challenges

Aptum’s Global Cloud Impact Study reveals this with 62 percent of respondents citing complexity and abundance of choice as a hindrance when planning a cloud transformation. One of the biggest sources of complexity that crops up in more advanced cloud projects are legacy systems. The “abundance of choice” or the need to select the best of breed is a prime culprit. This usually results in a technological smorgasbord, where hundreds of decoupled cloud dev and migration teams make their own calls around what technology to use. Complexity naturally arises when it’s time to join and coordinate those apples and oranges. Read David Linthicum’s InfoWorld article.

The art of code reviews

According to Phil Hughes, front-end engineer at GitLab, it’s about how you provide and convey that feedback — and that’s an art form and a skill that is learned over time. “Reviewing code efficiently is a skill that gets learned the more you do it. Spending time coming up with a workflow that works for yourself is just as important”. Read the SD Times article by Christina Cardoza.

An AI can simulate an economy millions of times to create fairer tax policy

Scientists at the US business technology company Salesforce think AI can help. Led by Richard Socher, the team has developed a system called the AI Economist that uses reinforcement learning—the same sort of technique behind DeepMind’s AlphaGo and AlpahZero—to identify optimal tax policies for a simulated economy. The tool is still relatively simple (there’s no way it could include all the complexities of the real world or human behavior), but it is a promising first step toward evaluating policies in an entirely new way. “It would be amazing to make tax policy less political and more data driven,” says team member Alex Trott.

At the end of an hour and a half of arguments, Justice Stephen Breyer, who at one point read aloud some code, seemed to be the only sure vote. Several of the other justices, including Chief Justice John Roberts, suggested they were sympathetic to Oracle’s copyright claims. Several of the court’s conservatives, including Justices Brett Kavanaugh and Samuel Alito, noted that Google’s allies had warned that the “sky will fall” if Oracle won. But those comments were also peppered with skepticism. “I’m not aware that the sky has fallen in the last five or six years,” Kavanaugh said, noting that Google had lost its first appeals court battle in the case in 2014.

Section 230 will be on the Chopping Block at the Next Big US Congressional Hearing

Will Section 230 be on the chopping block at the next US congressional tech hearing. Hearing will focus on Section 230 of the Communications Decency Act, the key law that shields online platforms from legal liability for the content their users create. What is clear: Tinkering with such a foundational law could have a huge cascade of effects for the internet as we know it and isn’t something to be undertaken lightly — if at all.

To the moon and beyond: How HoloLens 2 is helping build NASA’s Orion spacecraft

When workers for Lockheed Martin began assembling the crew seats for a spacecraft designed to return astronauts to the moon and pave the way for human exploration to Mars, they had no need for paper instructions or tablet screens to work from. Everything they needed to see, including animations of how pieces fit together, engineering drawings and torque values for tightening bolts, was visible in HoloLens 2 devices that they wore.

Affordable AI: Nvidia Launches $59, 2GB Jetson Nano Computer

While Raspberry Pi boards are great for doing all kinds of tasks and they’re capable of doing object recognition, they can be a little slow when it comes to real-time image recognition. In 2019, Nvidia came out with an A.I.-focused Pi competitor in the $99 Jetson Nano. Fast forward to 2020 and Nvidia is back with a 2GB version of the Jetson Nano that sells for a more reasonable $59 and, for consumers in some markets (including America), comes with a compatible USB Wi-Fi dongle in the box. Due out later this month, the new Nvidia Jetson Nano 2GB is designed to make A.I. more accessible to hobbyists, kids and aspiring developers. Read the Toms Harware article by Avram Piltch.

Why Apple needed the FDA to sign off on its EKG but not its blood oxygen monitor

The features on the Apple Watch that track heart rate and heart rhythm, though, have a key difference from the blood oxygen monitor: the heart-tracking features are cleared by the Food and Drug Administration (FDA), and the oxygen monitor is not. Apple went through a long, extensive process to develop and validate an EKG feature so that the watch could detect a condition called atrial fibrillation. It didn’t need to do the same thing for the pulse oximeter. Blood oxygen monitors, or pulse oximeters, are considered Class II medical devices by the FDA. Read TheVerge article by Nicole Wetsman.

JDK 16: What’s coming in Java 16 (due March 2021)

Java Development Kit (JDK) 16 has begun to take shape, with proposed features including concurrent thread-stack processing for garbage collection, support for C++ 14 language features, and an “elastic metaspace” capability to more quickly return unused class metadata memory to the OS.

Microsoft launches Playwright for Python for automating testing

Microsoft is trying to make it easier for developers to automate their end-to-end tests. The company has announced a preview of Playwright for Python, which allows developers and testers to write such tests in Python. According to Microsoft, automated end-to-end tests have become more important than ever as teams build apps that run on a number of different kinds of devices. The increase in the number of targets coupled with increased delivery speed has put more pressure on the testing process, and automation is crucial to enable testing at the speed it needs to be done. Playwright for Python provides timeout-free automation, which makes it more reliable. Read the SD Times article by Jenna Sargent.

Definitely not Windows 95: What operating systems keep things running in space?

To deal with unforgiving deadlines, spacecraft like Solar Orbiter are almost always run by real-time operating systems that work in an entirely different way than the ones you and I know from the average laptop. Operating systems used in space add at least one more central criterion: a computation needs to be done correctly within a strictly specified deadline. When a deadline is not met, the task is considered failed and terminated. And in spaceflight, a missed deadline quite often means your spacecraft has already turned into a fireball or strayed into an incorrect orbit. There’s no point in processing such tasks any further; things must adhere to a very precise clock. Read the ArsTechnica article by Jacek Krywko.

GitHub Code scanning is now available!

One year ago, GitHub welcomed Semmle. We’ve since worked to bring the revolutionary code analysis capabilities of its CodeQL technology to GitHub users as a native capability. At GitHub Satellite in May, we released the first beta of our native integration: code scanning. Now, thanks to the thousands of developers in the community who tested and gave feedback, we’re proud to announce that code scanning is generally available.

Technology News Worth Reading

Posted on by davidi

Here are a few technology news stories that I’ve read in the past week or so.

News Headlines

Reading Code Is a Skill

The problem is not that we shouldn’t write readable code. Of course we should aim to write readable code, if only for our own poor selves further down the line (there is no one less capable of reading my code the following week than me). The problem is that these two issues are not mutually exclusive. It’s not “write readable code” or “learn to read code”. Read the DZone article by Trisha Gee.

When a digital twin becomes the evil twin

A digital twin is a digital replica of some physical entity, such as a person, a device, manufacturing equipment, or even planes and cars. The idea is to provide a real-time simulation of a physical asset or human to determine when problems are likely to occur and to proactively fix them before they actually arise.

The NVIDIA-Arm merger could change how we work

If the merger between Arm and NVIDIA is approved (I expect Great Britain, the EU, and China will have reservations), the result could be a massive change in AI capability. And, given that Arm is dominant in mobile devices and IoT, and NVIDIA is dominant in both graphics and AI training, it’s a merger that could have a dramatic impact on how we work as well.

Don’t write off government algorithms: Responsible AI can produce real benefits

There are many cases in which government bodies can deploy AI technology in lower risk, high-impact scenarios that can improve lives, particularly if they don’t directly use personal data. So before we leap full pelt into AI cynicism we should consider benefits as well as risks it offers, and demand a more responsible approach to AI development and deployment.

Postman’s New Schema Validation Feature Helps Encourage API Spec Literacy

Postman, an API development platform provider, has announced that its API Builder is gaining the ability to validate API schemas in real-time via a new UI pane that is accessible in the tool’s define tab. The addition of this functionality helps to provide developers with real-time feedback and encourage API specification literacy. Read the ProgrammableWeb article by Kevin Sundstrom.

Microsoft open-sources fuzzing test framework

Microsoft is looking to help developers continuously fuzz-test code prior to release, via the open source OneFuzz framework. Described as a self-hosted fuzzing-as-a-service platform, OneFuzz enables developer-driven fuzzing to identify software vulnerabilites during the development process. Read the InfoWorld article by Paul Krill. Access the OneFuzz framework on GitHub.

IoT Platform – Binding the IoT Ecosystem Together

The word IoT has meant many different things to different people, none of it is wrong in any sense. It has been just a matter of perspective. Device and sensor manufacturers think of it as the sensors at the center of the IoT ecosystem with some connectivity and software around the sensors to capture and transmit data. Network services providers think of IoT as a secure network that connects a bunch of commodity sensors to a backend data store. BI and Big Data platform providers think of their role in IoT as the most important; after all if you cannot process a large amount of data coming through and extract intelligence from it, what’s the point in putting all these sensors and networks in place.

Tourists on Tech’s Toll Roads

The recent trend is toward systems that are increasingly more closed. Unfortunately it’s only the latest in an ongoing cycle throughout the history of computing between open highways and private roads. Each swing in the pendulum moves from public, open, shared innovation that lays the open roads to private companies who use those public roads to build their for-profit toll roads. Those companies fight to ensure that no matter what signs you follow, you end up on their private road. Read the blog post by Kyle Rankin.

4 Python type checkers to keep your code clean

Over the last few years, though, Python has added support for type annotations, inspiring a whole culture of software devoted to type checking Python during development. Python doesn’t check types at runtime — at least, not yet. But by taking advantage of a good type checker, riding shotgun with you in your IDE of choice, you can use Python’s type annotations to screen out many common mistakes before they hit production.

Interview with Homage’s Gillian Tee on how technology can serve the world’s aging population

According to the United Nations, the fastest-growing age bracket worldwide is aged 65-years-old and older. At the same time, there is also an acute shortage of caregivers in many countries, complicated by high rates of burnout in the profession.

Refactoring from single to multi purpose

For the second time this year I’m refactoring a program from a single purpose to have two or more modes of operation. Both times the start and end result is similar, just the processing is different. A classic case of using polymorphism. The first program was a tool to process videos from speakers, find a face and export the subframe around it into a new video. The first mode was a good approach to test it, and gave results for some speakers. The second mode did a complete scan first, and then gave a smoother video for some videos.

New in C++Builder/Delphi 10.4.1 IDE: Package LibSuffix Auto Choice

Posted on by davidi

The C++Builder and Delphi Project | Options | Description page allows developers to

  • Choose and Set build target configurations
  • Write a description for the package
  • Set strings for the package library filename’s prefix, suffix and version
  • Define the use of the package (designtime, runtime or both)
  • Specify how the package is built (rebuild as needed or explicit rebuild)

In previous versions (version 10.3 and earlier) of C++Builder and Delphi developers building packages needed to manually set their package’s library suffix setting. The DocWiki “What’s new in version 10.4.1” mentions a new IDE projects option for setting the library suffix:

“Package AUTO libsuffix: packages can now have an automatic version suffix, instead of manually updating and specifying the right version suffix with each new release. (The compiler quietly supported this in 10.4, but full support for the feature in the IDE and package project settings is introduced in 10.4.1.)”

While you can still set a string for the library filename suffix, selecting the new ComboBox choice, “$(Auto)”, allows the compiler to set the suffix to match the package build version used by the compiler. For each target build (debug and release) and OS platform the resulting package filename follows a pattern:

Win32 and Win64: <prefix>Package1<suffix>.<version>.bpl
Android: <prefix>Package1<suffix>.so.<version>
macOS and iOS: <prefix>Package1<suffix>.<version>.dylib

Creating and building a package with Delphi and C++Builder version 10.4.1, choosing the $Auto option for the suffix and setting other Description page settings results in a filename like the test package project images shown below.

C++Builder and Delphi also support package-specific compiler directives to include in a package project’s source code.
