@zbigi, I see where you are coming from, assume that colder air can hold less water. That being said, just now it is 8 C outside and 11 inside so not much of a difference! Still, might try opening windows wide open first thing in the morning when it is cooler outside.

@chenda, where I live the building is over 100 yo, but not sure about the material but it definitely isnt 'modern . Problem is, the building opposite within the enclosure is a derelict industrial revolution warehouse and that space there is generally really damp, and I think this contributes to the issue as the road facing room is perfectly fine. What is the matter with double glazing? Windows here are double glazed.

If they are already insitu there is probably nothing wrong with them, although thinking about it they may be contributing to the damp problem if the trickle vents are not sufficient. The environmental issues arises with endless retrofitting and replacement of perfectly good single glazing. The UPVC units contain massive amounts of embodied energy and frequently fail before the end of the energy payback period, and end up in landfill. Timber is framing can last for centuries if well maintain. Secondary glazing is usually much more cost effective and achieves similar results, and also provides the acoustic and additional security benefits.

Yeah, double glazing may cause damp issues to arise in older properties because they prevent the breathing that chenda described; you're sealing a unit that wasn't meant to be sealed. Closing off chimneys and other such efficiency measures can do similar.

Wow that was a lot of exchange in my journal the past few days, need to be mindful of this as I have a cunning plan to reverse engineer my FI journey to the 500th post.

2023 update 4/52

Job

017/156 weeks in (ca. 10.9%).

I got enrolled in a one day workshop about building dashboards with a programming language called DAX in Power BI, this is a MS software. It falls in mid February.

Otherwise, I have been reinventing the wheel building extensive macros in SAS which effectively are functions. Writing a script with many of them in one SAS program is equivalent of building a package, like an R or Python package. Lots of work can be quickly done with a proper setup of macros I feel, and I am aiming to optimise this area. I have a lot of fun doing it.

Otherwise I wrote the first part of a publication that goes live next month.

I am working on another piece that is going live in April, but the datasets are messy. so this actually serves as my playground for developing the macros I have been writing about.

Maths and Stats / Studies

I am working on queues, epidemics and lifetime modelling. So operational research, epidemiology and actuarial science 101 for statisticians, someone could say. Later this weekend I will be working on genetics, renewal models and diffusion processes. I am a bit behind in my plan of one assignment a week until my trip to South America in March. The good news is that I have all but one assignments that fall in the period I am away out of the way. Only one left, and only because the material for it is not available so far.

Also, I heard back regarding the research bursary to do with graphs and networks I applied for last week. Again I did not get it. This time however I got a more encouraging response, where the coordinator had written a personal message saying how he regretted there not being enough funding for me and that I was the first candidate under the funding bar. A couple hours later the post doc whom I wanted to do the project with reached out offering an informal internship project. I wrote him saying I am keen. I like this stuff and can hardly see how it could be possible to be canned as a glorified technician in this field. Anyway, this would be no strings attached I presume so let's spin the serendipity wheel. Pretty happy about the opportunity, let's see where it goes!

So many brainy people here, chip in if you have a comment about the above!

The flat reclaimed

After lots of excellent advice, our flat is reclaimed. A combination of many good tips above, plus yesterday the dehumidifier arrived. 200W and can be set to start running when energy is cheap. After last night when we had it in sleep mode in our bedroom, the humidity levels were considerably lower throughout the day in that space. Across the flat, readings were in their 60%s (also due to open windows it was a nice day). I have also noticed that the reading on those cheap readers DW got are a few percent higher than the reader on the dehumidifier, to err on the side of caution probably believe the higher ones.

I plan to gradually be knocking down humidity across the flat and tonight will run it in the kitchen for the night, then living room, then corridor, bathroom etc and see how it goes. Nice that things are under control again.

A bonus: nice that we now have a dehumidifier for drying laundry (an issue I have been writing about in the past).

No-heating in the winter experiment to continue. I think we are past the peak actually. I did run the heater a few times but not for its conventional purpose, so I will write it off and say that the experiment is fine and well.

Food

We continue to get lots of food for free, eating heaps and heaps of greens, brasicas, other veg, fruit, berries, sometimes we spoil ourselves with a dark rye sourdough bread if we spot one, too. Otherwise we are running out of legumes, black beans are slowly coming to an end. Next 25kg bag of legumes will be lentils I think.

I estimate we spend less than $50 a month for our excellent varied diet.

Suprisingly to me, my experiences of years of running air purifier during winters (for polluted air) has shown that the location of the purifier doesn't matter - the PM2.5 content in the air falls almost evenly across my 38 m^2 apartment (I haven't checked the bathroom, and I have no other doors inside, so the air flows freely between rooms). So, it may not be necessary to move the dehumidifier around?

Thanks both, that's the sort of middle world physics I like. I also have a good book on mechanics of different sport disciplines.

I screwed up the setting of the dehumidifier last night so cannot judge, but I will move it around across the coming week to see anyway.

Heard back from the postdoc, he is suggesting a laid back no pressure project to look at the general position problem and its variations. Why not, I might take a book on graphs on my trip in March to have something to read.

2023 update 5/52

Job

018/156 weeks in (ca. 11.5%).

Having good fun dissecting and gluing together cryptic datasets to get to know their ins and outs.

This past week I have learned that there is still a pot of money left for trainings in my team so I am trying to think what training to do with data science I could suggest to take part in and have funded. If anyone has good ideas, let me know. I think I could realistically ask for a training with a price tag up to $1000 or £1000 (though that would be a stretch I think but possible).

DW job

Good news! DW is now doing a one year placement at a company to do with energy, to finish in late summer. A couple of days back, she had been offered and accepted a position in the company's IT department from late summer onwards. DW is happy and I am happy for her, too. She wanted to work in IT so there you go. Also, this means a 60% pay rise for her. It's a sort of graduate program, she said she might be heading to the US, continental Europe or somewhere else for placements up to several months.

I think we will be back to the savings levels from our previous life where our salaries were relatively low but expenses were through the floor. Now expenses are just mainstream low, and salaries will be both above median so savings rate will oscillate around 65-85%. Still, this is not the US or Switzerland, there savings rate with our lifestyle would probably be in the 90%'s.

But the way life is heading now, it is becoming increasingly possible to make our way many places with ease.

In fact, I would be rather keen to follow DW somewhere as the last few times I was more of the driving force of our relocations and life rearrangements.

Maths and Stats / Studies

Reading on the theory behind linear regression models.

Food

Ordered 25kg of organic brown lentils, it was about $75. 25kg bag of black beans lasted us about 9-10 weeks.

Thanks for reading!

I classic text if you have not seen it already is- Plane Answers to Complex Questions : The Theory of Linear Models. It may be what you are referring to.

1.3 kg of legumes per person per week! That's amazing, are half your calories coming from lentils alone? 0.5 kg a week is about all I can handle.

@mF, thanks! I am using tailor written books for the BSc I am doing (this is handy as they come in the whole BSc package so I just get the paper copies delivered home) but get referenced to other sources. Never have time to look up the references. Will try to make time to look at this one!

@basuragomi, I wouldn't be surprised. One bulk is legumes and the other whole grains (currently have barley and rye). I normally cook 600g of each overnight and with this cycle it comes to not needing to cook roughly every fourth night (for two people). Otherwise we eat a lot of fruit and veg which are bulk rich but not calorie rich, and something like 2-5 table spoons of nuts and seeds. Then we occasionally have treats like peanut butter, tahini, jam, honey, bread, last month we scavenged 1.5 kg mango chutney through the food scavenging app so will add a bit of that. And herbs and spices, a wall full of them.

My reasoning is that the savannah version of myself would probably not fuss about the food in front of them. The modernist version of myself gets in touch with the savannah one and tells them what science deems to be good stuff. The result follows. But other than that I am also fortunate in that I (and DW) like the diet.

With the legumes, we soak for 12-24h with 1/8 teaspoon of soda bicarbonate, change water 1-3 times, makes a difference in that the legumes are much less heavy.
