Call for Papers for the Validated AI for Pharma Summit is officially open.

Details: https://t.co/Iv4D1abU1c

If you are building, validating, or deploying AI in a regulated pharma environment, we would love to hear what you are learning.

We are organizing a free, virtual summit in September, and we are looking for practitioners with real lessons to share: what worked, what broke, and what you would do differently.

Topics we are particularly interested in:
🔹 Clinical trials and data-driven drug development
🔹 AI validation and regulatory compliance
🔹 Open source tooling in pharma
🔹 Getting AI from experimentation to production

We are especially interested in talks that get into the specifics: real decisions, real constraints, lessons other teams can actually use.

CFP closes July 31, 2026. Decisions go out by August 15.

I stand with Ukraine

Proud to live in a country (the Netherlands) that unconditionally supports Ukraine.

Europe needs to re-arm to support Ukraine, defend itself & democracy.

Ukraine is the one defending Europe from Russian aggression & should be part of EU.

This war bores everyone, doesn't it?

https://t.co/VbVH7WpJyy

I'm not bored, because I'm convinced that if we're bored with war today, we'll will have it at home in a few years' time. There are many signs of this, even President Biden says so - if Ukraine falls, the NATO countries will be next. Poland, on the other hand, is not a country on the eastern flank, as is sometimes said, Poland is a NATO front country. Therefore, I am convinced that we should support Ukraine's armed forces in our own interests too. I will continue to do so in the future as best I can.

As some of you may know, at the beginning of this year I organized a fundraiser to which you contributed more than 150 000 EUR zlotys: With this I bought 4x4 vehicles that I prepared for the conditions on the front, bought drones, including a Matrice with a thermal imaging camera for more than 20 000 EUR, bought rifle accessories, night vision devices, scopes, generators and many other things which, thanks to the indispensable Monika Andruszewska, I personally brought to the front, to the trenches and into the hands of the soldiers fighting against Russia.

I was at the front three times in Ukraine. I wrote two essays about this experience, which were published in Polish in Gazeta Wyborcza, in German in Neue Zuercher Zeitung and (one of them) in English in The Point. Links in the comments.

So everyone is bored with this war. But I think of my buddies I've met in this war and they can't be bored with the war. So I recently asked one of them, Dima from the Marine infantry, who is in the south right now, on the banks of the Dnieper, what they need.

"What do we need? Man, FPV drones and REBs. That's the most important thing right now," replied Dima.

"Look. A mortar shell costs about one thousand euros. An FPV drone costs between five hundred and one thousand euros. To hit something with a mortar, we have to fucking fire ten grenades. And an FPV drone only needs one. Do you understand what the difference is?

FPV drones are weapons that are as improvised as they are deadly. They are created mostly from Chinese components and assembled by volunteers, specialized companies or units themselves. Their sole purpose is destruction - the entire design is subordinate to this purpose. On the back of the drone are the battery and antennas of the video transmitter (which usually uses an analog rather than digital signal that is more resistant to jamming), underneath are the quadrocopter's propellers and motors, and on the belly is the payload - a bazooka warhead, a mortar shell or something else. All of this is held in place by zipties.

The pilot usually works with a navigator and a second team flying an observation drone to get a wider view. The drones have a range of about fifteen kilometers, depending on the size of the payload. Their advantage over commercial drones, which cost at least three thousands eruos and from which small shells are dropped, is the weight of the explosive charge or the effectiveness and, above all, the price. The ZSU loses thousands of drones every month - an FPV drone is six times cheaper and much more effective than a Mavik or Matrice with a grenade. Their mere presence on the front line changes the whole situation:

"With an FPV drone I can easily fuck up their tank, a IFV, cars and pick-ups, even while they are on the move, which is rather impossible with a mortar", Dima told me. "For this reason, Russians has to keep its machines at a distance, with tanks they shoot from afar, but they are afraid to drive up, because everything we notice can be destroyed. They keep everything at least ten kilometers away from the null. The topic of FPV has been around for a year or a year and a half, but now we have the problem that Rustia has more of it than we do. So you can understand it yourself. The whole machinery of the empire is working with them for this, the Chinese are helping them, you know?

Every war has its swords, it also has its shields.

Shields against drones are jammers. The Ukrainian soldiers, like the Russians, call them REBs - РЕБ, stands for "Радіоелектронна боротьба", radio-electronic warfare.

"There are many types of REBs. The Russkies have great radio-electronic warfare systems, and in this field they have an advantage over not only us, but over everybody else," Dima continued to explain to me in a signaled voice. "Their jammers are such big machines, with a big antenna that are easy to identify, and we have destroyed many of them for them. That's why they use such smaller ones now, they call them "trenchers', and they drown out everything, right? All communication channels. And the antenna is barely visible. Well, and now we need some that can be mounted on cars, and for us, in the naval infantry, also on the boats that we sail across the Dnieper. We, the pilots, are on the right bank and our infantry on the left. For them, the entire supply goes by boat, and you can't hide on the water. Without an REB, as you understand, such a boat is doomed."

But REBs can't be just any kind. In one airborne brigade I know, the guys were sitting in positions a few hundred meters from the borders of Bakhmut, of which they were among the last defenders. The whole platoon share the cost with their own, private money and bought the cheapest REB, because the Russians were attacking them from the ruins of the burnt city with whole waves of FPV. For three days after the purchase, they rejoiced at the sight of Russian drones dropping far in front of their positions, drowned out by the REBs, without harming the boys. On the fourth day, the Russkies changed their frequency and a drone flew directly into their trench.

This terrible war will end successfully if we get bored, not with us, but with the Russians. That's why I want to help my Ukrainian friends to make it a bit more unpleasant for the Russians.

That's why I'm appealing to your generosity once again: donate, please. I will use everything I can raise to buy FPV drones and REBs from trustworthy and military-proven suppliers. Then I'll put everything in a car and, together with Monika Andrushevskaya, personally take it straight to the trenches, to the units we've already helped, namely

- 72nd Mechanized Brigade, where I spent most of my time,
- the 77th Airborne Brigade, where a company is commanded by my colleague Dzhura, whom you've already met if you check my social media from time to time
- to the naval infantry in Kherson,
- to the special forces, to Omega and other SSOs of the ZSU.
