Teach this to your manager: At the beginning of a task, uncertainty is highest. Under no circumstances should you give an estimate in ‘man-hours’. Even days is too precise. The first estimate should be in months or years (of course depending on the size of the project). Then, as your insight into the project grows, you refine that to months, then weeks, later days. A vague estimate with a lower and a higher bound is way more useful to your manager than a ridiculously ‘precise’ but highly speculative number.

This lesson was brought to you by either “Code Complete 2” or “Rapid Development” by Steve McConnel, and by my former manager who wanted projects estimated in minutes.

duh? One is a completely passive ‘experience’, while the other is more akin to a hobby: You perform an action, gain a skill and overcome obstacles that become more and more difficult.

Editierung: dabei fällt mir auf dass die Pläne in meiner Stadt sogar noch weitaus schlechter sind mit (je nach Linie) nur 4-7 Fahrten pro Tag pro Richtung.

Das hier ist der Plan für die Fahrt von der Kleinstadt in die nächste Großstadt. Deshalb fährt hier ungefähr stündlich ein Bus. Frag nicht nach den Linien, die die Dörfer an die Kleinstadt anbinden.

Kontext: Die Buslizenzen bei mir wurden neu vergeben. Jetzt fährt mein wichtigster Bus stündlich immer zur selben Uhrzeit. Vorher waren die Zeiten zufällig.

Selbst Schuld, wenn man für jede triviale Erkältung 50€ in die Apotheke trägt.

Is this where the word ‘dressing’ comes from?

This is my googled understanding, take with a grain of salt:

Batteries contain of lots of individual cells. If you short-circuit one cell, you generate lots of energy (from the short-circuit), and start a chemical reaction (fire) that does produce its own oxygen. Once that cell has lost all its charge, the reaction would stop, but until then the fire has compromised neighboring cells, which start the process all over again.

Water won’t stop the first broken cell from discharging, but it can bring the battery down to a temperature where the fire is too cold to sustain itself. It contains the damage to the cells that are affected already and prevents more cells from igniting. This is how you stop a battery fire.

The car gets put into a tank for several days to allow the broken battery cells to discharge safely, without overheating and causing another fire.

Ich kann’s verstehen. Eine Mitgliedschaft ist billiger, als sich so ein (mäßig wertiges) Teil selbst zu kaufen. Abgesehen davon, dass ich mir das echt nervig vorstelle, unter jemandem zu wohnen, der sich regelmäßig auf ein Laufband stellt.

Warum nicht an der frischen Luft laufen? Gerade am Anfang ist man so schnell an seiner körperlichen Leistungsfähigkeit, dass man sich den anderen nicht als Verkehrsteilnehmer zumuten will. In besserem Trainingszustand mag das gehen, aber auch da hat man das Problem der fehlenden Vergleichbarkeit. Man will ja ungefähr überwachen, wie sich die Leistungsfähigkeit steigert. Es ist aber sauschwer nach Daumenmaß eine konsistente Geschwindigkeit hinzukriegen.

It is common practice to submerge EVs in water for several days in Germany, too. Remember that there is no elemental lithium (which would react with water) in batteries. As with every fire, the goal is to cool down the battery, so the fire doesn’t have enough energy to burn further. Unfortunately I only found German sources to back this up.
