Sequels

Our math and science columnist Eef has published a series of articles on AI and Math. These articles are best read in the correct sequence for easy understanding. There are also a few articles on AI from my hand. Check out this page to get it right. Continue reading →

Development software development

Cryptic? Let me explain: As a carpenter needs a hammer and a saw to build anything, in order to develop software, a software developer (aka computer programmer), needs tools for software development. Of course, today’s carpenter uses a nail gun and a circular saw, preferably battery-driven – there is progress and development even in the tools of a trade. Similarly, tools for software developers have evolved from simple text editors to advanced dedicated programs supporting every finesse of the programming language to be used. Sometimes these tools are free, in other cases you have to subscribe to them.

However, sometimes the development of these tools stalls or grinds to a complete halt. This can present a real challenge for its users. Continue reading →

Windows 11, or rather Linux?

My computer of choice is, has been for a long time, and probably remains to be for the forseeable future, a 2008 Lenovo X220 laptop. Yes, I’m aware that it is rather oldish.  When it was new, it must have been a beast of a machine, and likely sported quite the price tag. Today, close to 20 years later, it is still a fast laptop. It boots in under a minute and shows no delays in loading files or web pages. Of course, it came with a spinning hard disk when new, but I swapped that out for a Solid State Disk (SSD) years ago. The internal memory was with 16Gb already up to spec, it came standard with a 64-bit processor, and it never was, nor is today, a slow machine. It ran Windows 7, then Windows 10, and then….Microsoft said NO!

Say what? You heard me, they said NO, you ain’t gonna run our shiny new W11 on that old thing! Continue reading →

Putin’s Christmas wishlist

Two days ago, from the time I write this, a peace plan for Ukraine was leaked, most likely from the White House or from the Pentagon. It didn’t reveal much detail, but from any of those sources, anything could be expected. Two days in and the contents all over the news, I can confirm that it must look exactly like the put’n wishlist for Christmas presents. And there’s nothing in it for Ukraine. Continue reading →

De fietsenwinkel

Mijn vader was er ‘een van de fietsenmaker‘. Daarmee werd zijn vader Herman van Doorn bedoeld, die in Beverwijk sinds begin van de vorige eeuw een fietsenwinkel dreef. Mijn opa werd opgevolgd door zijn oudste zoon Hennie, en daarna nam collega Cock het vaandel over. De zaak bestaat nog steeds, en verkoopt en repareert ook vandaag nog steeds fietsen.

Het pand bestaat ook vandaag nog op dezelfde locatie waar het meer dan 100 jaar geleden begon, maar is niet meer actief in gebruik als fietsenwinkel. Deze winkel verhuisde een paar jaar geleden naar de Beverwijkse Breestraat, en naar de nieuwe vestigingen in Heemskerk en de Velserbroek. Continue reading →

Alternatief voor een dure EV

Elektrische auto’s (EV’s) zijn de toekomst. Althans dat doet de overheid ons denken, en de autobranche speelt daarin uiteraard vlijtig mee. Maar is dat wel zo? Of is er ook een toekomst voor niet-EV auto’s?

Hier in Zweden kost de goedkoopste nieuwe EV rond de €30.000. Dat was een Citroën die er prat op ging de goedkoopste EV in de markt te hebben. Ter vergelijking ging de voordeligste EV in Nederland toen (2024) al voor ruim onder de €20.000 over de toonbank. En dan hebben we het slechts over de instapmodellen, de meest verkochte modellen hebben in Zweden prijskaartjes vanaf €45.000 tot tegen een ton! Wie kan zich dit veroorloven? En dan als tweede auto?

Zen and the Art of the Book Cover

I have good memories on reading M.Pirsig’s novel ‘Zen and the Art of Motorcycle Maintenance‘. It was the Dutch version, so I now know some nuances were lost in translation. Also, it was over 45 years ago, and with that, it is long overdue for a new read.

Covers:

If I may believe the more than a handful of accomplished bestselling writers’ groups on Facebook, I have to invest in hiring a professional to design the cover of my books. In traditional publishing, with a publisher’s house, they will take care of this as it is included in their fees. But when self-publishing as I am, the consensus seems to be to hire an accomplished artist with experience in book cover design, and let this person create an attractive cover for your book.

Ukraine – Book sales donated

Summary:

Today, the money collected from the book sales for my book ‘Ukraine – Infrastructure victory’ was transferred to the organization Help99. Exactly 20 books exchanged hands; some were sold, others donated. For the donated books, I footed the money it would have made in sales. Two buyers chose to pay more for the book than I was asking; I thanked them and added the full donation to the account. Those who bought a copy off me: thank you!

Two copies landed in different libraries, one in a private community library in Spain, the other in the communal library in Knivsta, Sweden, where we live. Of course, for these books I also footed the assumed sales profit.

Some books have been promised as a donation but have not yet been delivered. I preemptively added the assumed profit to the list. Continue reading →

Felkodens magi

Moderna bilar fick utan undantag en ny varningslampa för sådär 25 år sedan, motorlampan:

Lampan är fruktad och samtidigt älskad av många. Den lyser när bilens ‘dator’ har upptäckt något som avviker från det som den förväntar sig. Efter det börjar lysa bör man enligt instruktionsboken besöka verkstaden som kan läsa ut felkoden och berätta för dig som kund vad som är trasig och hur många tusenlappar det kommer att kosta för att lampan släcks. Medan det låter enkel, oftast är det mycket mer komplicerat än så. Continue reading →

The art of the sale

Anyone who knows me can vouch that I’m not much of a salesman. Au contraire, I can easily state that I have got to be the worst salesperson in the history of sales! In my latest project, I decided to write a book about a covert espionage operation in russia, with the goal to undermine russia’s infrastructure to the point where it would be more than noticeable in society, government, and military. The book was written and then published earlier this year.

The idea of this project was to sell as many copies as I could, deduct the (very low) printing cost from each sale, and send the remainder – the total profit – to an organisation that helps civilians and military in Ukraine. Due to my poor sales skills (it cannot be the book, ’cause that’s great!), hardly any sales were made. Continue reading →

De Tour de France 2025 – Impressies

Tour de France, etappe 9, 13 juli 2025

Na alle opwinding van de voorgaande dagen zou dit een rustige, zelfs saaie etappe worden. Een volkomen vlakke rit over 174 kilometer eindigend in een massasprint. Het liep anders.

Mathieu van der Poel’s ploeggenoot, de Belg Jonas Rickaert had geroepen dat hij ook wel eens op het podium wil staan en hij vroeg of Mathieu hem hierbij wilde helpen. “Natuurlijk,” had deze gezegd. “Gaan we voor zorgen.”

Direct na de start reden de twee weg. Niemand in het peloton nam dit serieus, niemand volgde. Gestaag werd de voorsprong uitgebouwd en na 80 kilometer was dit opgelopen tot iets meer dan 5 minuten.

Nu werd er toch wat onrust zichtbaar bij de ploegen, normaal is er niets aan de hand maar het ging hier wel om Mathieu van der Poel. Continue reading →

Writing – How to secure your manuscripts

As you hopefully are aware, I’ve done a fair bit of writing and publishing. Currently, this activity is now waiting for new inspiration to arrive, but the days of a new book certainly will come again.

When I’m not writing, I’m active on several Facebook groups on various subjects, and have also joined and am active on several writing groups. A frequently recurring question in several of these groups is from folks tragically having lost parts of or complete manuscripts. In close to one hundred percent of these cases, no copies of the work in progress (WOP) were saved elsewhere. Continue reading →

How about Iran?

Yesterday, as I am writing this, the US decided to bomb Iran’s nuclear facilities deeply buried under tens of meters of concrete. Whilst this may seem like a good idea any day of the week, it certainly escalates the already high tensions in the Middle East. It also may bring the US something the current regime said it would avoid at all cost: WAR. Continue reading →

New book – Ukraine (all sales profit will be donated to Ukraine)

Again, a new book is close to publishing published and available for sale:

Ukraine – Infrastructure victory

The total profits of this book go to help99.co, an Estonian nonprofit that collects funds to help Ukraine. The help is not only Ukraine’s citizens with everything from medicines and fully equipped ambulances to solar panels and generators. But also for the front lines eg. by supplying ambulances that can work in combat circumstances.

So, buy the book and you contribute to the freedom of Ukraine, it’s as simple as that. And as an added bonus, you get to keep the book! Continue reading →
