Predictability

I love models. Yes, metoo ... But I'm talking about algorithms here. Those who are a bit into mathematics know that with a little curve fitting you can go all the way. Lets aside Fourier. If you do not understand this, then I advise you to look at this Homer (Simpson) orbit example:
Maybe now you understand that a climate model can be made for any outcome. And then you also understand that it is wise to let the value of a model depend on any proof of the correctness of a model by testing it against measurements. The models of the club of Rome, for example, have not (yet) come true while they already beat the already known dates.

Is this bad? Not at all. We do not learn much without modeling and testing. I do have a problem with the way the press deals with modeling. They publish a scientific research as fact or almost fact at the moment that it offers sensational outcomes. Again something like that today!

'Coming four years will be unusually warm'

Fortunately, the text does add nuance "Drijfhout and his colleague concluded that the probability that the earth is warmer than normal until 2022 is according to them a consequence of a kind of break in global warming between 2000 and 2014. In that period the oceans have absorbed more heat, which is now coming back, but that expectation is dependent on other factors, for example volcanic eruptions and a changing amount of CO2 emissions can affect the global temperature. "

For the time being, meteorologists can not produce a reasonable weather forecast much further than a week ahead. Everything else is fun, interesting, valuable science, but nothing more. Whatever the press dakes from it.

Annoying stupid smart functions in Google WorkSpace

Annoying stupid smart functions in Google Workspace. For the context. I had enough of Bill Gates, his marketing and pushy sales force a long time ago. And have abandoned Microsoft completely in 2014. I never ever will buy anything from them again. Certainly, not ChatGTP (Babylon 2.0 in the making). And when Zuckerberg showed up, I rapidly saw he was a second Bill Gates and I never installed any app of him, and never will. So from US big tech, I only use Apple and Google stuff. Google and Apple are king in “thinking for you” in the wrong way . Consequently, making your live less efficient rather than more efficient. This writing is about that, based on example cases. The first disaster I experienced in this regard has been the day that Apple decided to organize my photo's for me. With as a consequence, my organization of my history was completely messed up. After a year, I decided to take all my images away from the iCloud and put them on Dropbox. Now I organize my history myself. W...

Information technology has become research all

Large Language models have changed the research landscape. We (Clocked Subjects and Objects) always have been more than an IT and software company.  The emerging of DeepSeek, changes the research landscape. And this is only the beginning. We Clocked S O are a HumanSys engineering company. We use a wide range of knowledge to develop new ways for humanity to exist more efficient. And IT has always been a key tool for us to do so. This (after the emerging of DeepSeek) will go faster and faster. This blog will keep on focusing on the IT side of things. Next to this blog, we have the blog related to the Free world people initiative, where we cover global free humanity development observations. We use human assisted AI to follow developments (news) in the main areas of human science development, as we have identified them: EnergoSphere; BioSphere and KnowSphere. If we have comments on the developments, you can find them there every day.

Issuing phone numbers, a failing public service.

The unreliable ID? In many articles, the IT industry complains about the fussy nature of the phone number as a reliable ID. For example, in this article . What wend wrong? The ITU It was original set up by governments to resolve international issues on standards for telecommunication. One of their standards is the Telephone numbering plan . This telephone numbering plan was set up in a time of fixed landlines, never considering mobile personal use. Who has ownership? Let's have a look at the international public telecommunication numbering plan E.164 . The first 3 digits are the country code or country calling code . Counties control the subscribers assignment in the networks of the member countries. So countries have jurisdiction over the subscriber assignment in the country networks. In that regard, the county calling code is the jurisdiction code ! National governments have ownership! To me, it looks like governments fail to provide the public service we (the people) could expe...
