Nach langer Zeit habe ich unser Whiteboard in der Küche mal komplett sauber gemacht, und dabei zwei Worterfindungen aus 2020 weggewischt, die ihre eigene Geschichte haben.

When do you throw your food away?
It is a challenge for all of us: we do not want to eat bad food, but neither we want to be bad for the environment or a shame to hungry people. So when do we throw our food away? When the date is expired, or when it looks or smells bad? Every person has its own way, but it makes sense to give it more thought. Therefore I made this diagram to make a fair and healthy decision.

Diagram to determine if your food is good or bad
Rule of thirds
When you buy a product, look at the 'best before' date. Count the days, weeks or months that is in the future and add one third: this is the more realistic date of expiration. So: the for milk you may have three days left, but you can probably use it four days; for a glass of vegetables for which you have 9 months will last 12, etc. Some products like flour, pasta, rice and some canned food will even last much longer. Meat that expires the next day, may last 0.3 day longer, but with such low margins you better stick to the date!
Why is it important not to throw it away on the expiration date? Because manufacturers reduce the expiration date every year silently and this seems an ongoing loop. So more and more food is wasted every year! See here (NL) and here (DE). Throwing it away on the expiration date is not very responsible.

The shelf life is actively reduced by manufacturers that set the expiration date earlier. As a result people are surprised that their food is expired earlier, but still throw it away, increasing food waste. They buy a new package instead. As a result sales go up. Now the manufacturers have an incentive to further reduce the shelf life of their products. Completely unnecessarily from the point of the food quality! Therefore it makes sense to use the diagram above to determine if you should throw your food away instead of the date!
Final notes
- It is mostly safe to follow the diagram here, but it is on your own risk. Internet resources like this one can give you advice but cannot be hold responsible
- The manufacturer can be hold responsible for food going bad when it happens before the 'best before date'. Therefore it is logical to have the date early set, but there are not any legal rules for how early.
- Because the date is set earlier year by year, the rule of thirds is very rough and may be one day rather a 'rule of halfs'.

De koffiespecht en de treinreis (NL)
De koffiespecht - ik kom er zo op.
Eerst even dit. Laatst zat ik in de trein en hoorde wat ik vaker hoor. Er werd omgeroepen 'Deze trein rijdt niet verder als...'. Wacht even, ver - verder - verst, DAN!, verder dan...
Tenzij de trein natuurlijk niet verder als stoptrein rijdt, maar als sneltrein (in de hoedanigheid van), dan is 'verder als' dus wel goed. Maar bij de vergrotende trap hoor je gewoon 'dan' te gebruiken, dat hebben we zo afgesproken. Toch wordt het misschien ooit 'verder als'. Als iedereen namelijk hetzelfde steeds fout zegt, dan is er een soort consensus dat het goed is. Afspraken, zoals bij de vergrotende trap, kun je veranderen.
Anders ligt dat bij grammaticale logica. Deze sneltrein word stoptrein, zonder t, is echt fout. Ook als iedereen het fout schrijft zal het nooit correct worden. Dit is namelijk logica afgeleid uit een algemene afspraak dat voor vele werkwoorden geldt. Als je dit zou toestaan omdat veel mensen het fout doen, dan zou dat op alle andere werkwoorden ook toegepast mogen worden. Dan krijg je gekke dingen als 'de trein stop niet bij het volgende station'.
Er zijn nog andere uitspraken die om logische reden onjuist zijn. Bijvoorbeeld 'de trein rijdt omhoog'. Dat kan niet. Een trein kan alleen maar in tekenfilms direct omhoog rijden, want 'omhoog' is een verticale beweging, net als omlaag. Zo zijn 'vooruit' en 'achteruit' de horizontale beweging. Een trein kan wel schuin omhoog rijden; mooier is echter 'de trein reed de berg op'.
Nou vooruit, nog een regeltje dan. 't Kofschip, 't fokschaap en xtc-coffeeshop hebben de medeklinkers t, x, k, f, s, c, h en p. Als de stam van een zwak werkwoord hierop eindigt dan gebruik je in de onvoltooid verleden tijd -te en -ten, en anders -de en -den. Het blijven rotwoorden. Wie onthoudt die nou? Dus kan er nog wel eentje bij; ik introduceer 'koffiespecht'.

De koffiespecht drinkt wel een kopje mee als het om de Nederlandse taal gaat! Gezelliger kunnen we niet maken ;-).

Free desktop backgrounds

A small present from Naturemoods.com, a package of backgrounds for you computer in the formats 1920x1080, 1280x800, 1366x768 and 1024x768. Download HERE.

A smaller fit can be elegant, supply a better overview of your icons and save energy with a black background.
How to use (Windows 10):
- Open the downloaded zip
- Copy the folder Backgrounds1 to "Pictures" (This PC)
- Go to your desktop and right-click on an empty spot, and choose "Personalize"
- Here you can set Background to "Picture".
- Important: Set "Choose a fit" to "Center" first! (Backgrounds are not made to stretch, span, etc.!)
- Click on "Browse" to choose you picture. Navigate to the folder Backgrounds1 in Pictures where you have put it.
- Now you can try different backgrounds to find out what your favorite is, in the size of your desktop. You can choose one that fits your background, but you can also choose a smaller one (as above in the example) when you wish.
- If you are done and still in the settings window, you see a list on the left. "Background" first and "Lock screen" as third. Go there, and select a picture here as well. You can also set "Show lock screen background picture on the sign-in screen" to ON.

Microsoft gegen Muslime, oder die Macht über unsere Gedanken?
Ach ja, dann nochmal: "wer aus Angst geflüchtet ist, auch ein Muslim, verdient Hilfe, weil wir Menschen untereinander sind, auch wenn der Andere eine Religion hat die wir nicht verstehen." Nur mal um alternative Gedanken im Gehirn zu aktivieren.

Obstfliegen loswerden - Das beste Rezept

Jedes Jahr kommen sie wieder in große Zahlen und versauen die schöne Zeit in der Küche: Obstfliegen. Mit dieses Rezept, basierend auf viele andere Rezepte aus dem Netz und einige eigene Experimente, werden sie angelockt und ertrinken. Die Mischung am besten auf einem flachen
Teller(chen) zusammen-mischen und irgendwo in der Küche hinstellen.
Hier kommt die Basis:
1 Tl Zucker
2 Tl Balsamico-Essig
1 Tl Zitronensaft
ein Schuss Wasser
ein Tropfen Spülmittel
Gut rühren bis der Zucker gelöst ist. Das Spülmittel bricht die Oberflächenspannung, wodurch die Fliegen direkt ertrinken.Viele Varianten sind möglich. Zucker kann man austauschen gegen Fruchtsirup, Zitronensaft gegen ein zweiter Tropfen Spülmittel wenn dieses stark nach Zitrone riecht, usw. Auch Weißweinessig und Gurkenwasser sind beliebt.
Historical image restoration - Reparatur von alte Bilder
Ich habe meine Seite mit der digitale Restaurierung alter Bilder erneuert und eine Liste mit Reparatur-Dienstleistungen hinzugefügt.

Mein Interesse für historische Fotos und deren Restaurierung hat mit dieses Bild von meinem Großvater auf dem Motor angefangen. Seitdem habe ich einiges dazu gelernt, und probiere ich regelmäßig neue Techniken aus, aus dem Buch "DIGITAL RESTORATION From Start to Finish".

Dieses Bild zeigt mein anderer Großvater als Kind (Mitte), seine Eltern (links und rechts) und seine Geschwister (oben). Auf 100% ist gut zu sehen wie gut Kratzer und Flecken zu entfernen sind ohne das Detail verloren geht.
Aus der gleiche Familie ein Bild, welches zeigt das auch Risse gut repariert werden können.

Zum Schluss noch ein Bild vom Vater des Motorfahrers aus dem ersten Bild. Extreme Verblassungen können meistens restauriert werden.

Two math questions for bikers: with interesting solutions!
1. When you are biking and you stop for 1 minute to put on a coat and your bike partner goes on, how long will it take before you keep up, by going 2 km/h faster? After what distance do you meet again?
Solution (simplified, ignoring the acceleration phase):
Between begin of stop and re-unite person 1 and person 2 have traveled the same distance (D). During the stop phase (Tstop) person 2 has continued to cycle with velocity 2 (V2). After the stop phase, person 1 has to gain with velocity 1 (V1) the distance that person 2 has cycled during the stop phase. The time required (T) to keep up is hence given by:
T = Tstop*V2 / V2-V1
and the distance:
D = V1*T
So say that the velocity of person 2 is 20 km/h and that of person 2 is 22 km/h to keep up. Tstop is one minute, 1/60 hour. If you use the formula you find that the time needed to keep up is 10 minutes and the distance 3.7 km.
Of course, numbers increase when the base velocity of the trip (and hence person 2) is higher or the time stopped is longer. Every second counts! Better you stop both :-)
2. When you are bicycling in the rain, would it help to go faster?
You are earlier at your endpoint by reducing the total time in the rain, but you also get wetter because you get more raindrops per time unit. By biking faster, do you get wetter, are you getting less wet, or doesn't it matter at all? Does the same apply for walking and motorcycling?
Rain is usually measured as rate in mm/h. After making some calculations on a sketch paper I found out that this problem is independent of surface and distance! The rain rate is normally applied to a non-moving object. The rain "receive rate" depends on the velocity of the object, not on it's surface. An object that moves twice as fast as another, receives twice as much rain per time unit. The rain rate can just be multiplied by the velocity to get the rain receive rate. If you then multiply the rain receive rate with the time required for a fixed distance, you will find that two objects moving with different speeds have received the same amount of rain at the end of the track. So when you are going faster, you are only faster to get dry clothes in a warm house! But if you know the rain is going to stop before you get home, slow down!
Feel free to comment if you have any addition or correction!
