16.04 – How to edit a .odt file from the terminal?

The closest thing to what you’re looking for is wordgrinder, a terminal-based word processor.

You can install it executing:

sudo apt install wordgrinder

Here is the official website of the project: https://cowlark.com/wordgrinder/

This is the Github repo: https://github.com/davidgiven/wordgrinder

And a quick Survival Guide: https://gist.github.com/davidgiven/1aba97e96a9b8f9b573b

If you check the Importing and Exporting sections you will find:

Importing

Imports basic content from ODT files. OpenDocument is complicated and hard to parse but WordGrinder will do its best to apply appropriate styles. Unsupported features are ignored.

Exporting

This produces an ODT file which can be read by LibreOffice and a variety of other major word processors. Character and paragraph styles are exported and are mapped to OpenDocument styles called P, H1, H2 etc.

Roche limit

In celestial mechanics, the Roche limit, also called Roche radius, is the distance within which a celestial body, held together only by its own force of gravity, will disintegrate due to a second celestial body’s tidal forces exceeding the first body’s gravitational self-attraction. Inside the Roche limit, orbiting material disperses and forms rings, whereas outside the limit material tends to coalesce. The term is named after Édouard Roche (pronounced ɔʃ] (French), /rɔːʃ/ rawsh (English)), who was the French astronomer who first calculated this theoretical limit in 1848.

Bicycle chain

Width

Chains come in 332 in (2.4 mm), 18 in (3.2 mm), 532 in (4.0 mm), or 316 in (4.8 mm) roller widths, the internal width between the inner plates. 18 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes. Chains with 332 in (2.4 mm) wide rollers are generally used on bikes with derailleurs such as racing, touring, and mountain bikes.[17] Fixed sprockets and freewheels are also available in 332 in (2.4 mm) widths so fixed-gear and single-speed bikes can be set up to use the narrower and lighter 332 in (2.4 mm) chains. Finally, chains with 532 in (4.0 mm) wide rollers are used on freight bicycles and tricycles.

With derailleur equipped bicycles, the external width of the chain (measured at the connecting rivet) also matters, because chains must not be too wide for the cogset or they will rub on the next larger sprocket, or too narrow that they might fall between two sprockets. Chains can also be identified by the number of rear sprockets they can support, anywhere from 3 to 12, and the list below enables measuring a chain of unknown origin to determine its suitability.

  • 6 speed – 7.3 mm (932 in) (Shimano HG), 7.1 mm (932 in) (SRAM, Shimano IG)
  • 7 speed – 7.3 mm (932 in) (Shimano HG), 7.1 mm (932 in) (SRAM, Shimano IG)
  • 8 speed – 7.3 mm (932 in) (Shimano HG), 7.1 mm (932 in) (SRAM, Shimano IG)
  • 9 speed – 6.5 to 7.0 mm (14 to 932 in) (all brands)
  • 10 speed – 6.0 to 7.0 mm (14 to 932 in) (Shimano, Campagnolo)
  • 10 speed (Narrow) – 5.88 mm (732 in) (Campagnolo, KMC)
  • 10 speed (Narrow, Direction) – 5.88 mm (732 in) (Shimano CN-5700, CN-6700, CN-7900)
  • 11 speed – 5.5 to 5.62 mm (732 to 732 in) (Campagnolo, KMC, Shimano CN-9000)
  • 12 speed – 5.3 mm (1364 in) (SRAM)

The Wikibook, “Bicycle Maintenance and Repair”, has more details on this topic. Shimano uses the same chain types on 6, 7,and 8 speed designs.

Problemi s perilicama posuđa

Znači, preostane jedino ono školsko razmatranje:

– svaka perilica prvo ispumpa vodu, smatra se da postoji preostali sadržaj šalica i sl. i to traje 20-30 sek (akustički: laaaaaah laaaaaaah laaaaaah)

– onda utoči svježu vodu otvaranjem niza elektroventila, to je tih zvuk bzzzzzzzzzzzzz i žubor

– nakon što utoči, trebalo bi otvoriti vrata da provjerite da li je vodostaj dostatan, obično je to 1-2 cm od donjeg ruba vrata

Ako ima radni vodostaj, kreće “prava akcija”:

– uključuje glavnu pumpu i to se čuje kako “bičuje” lim energično, dakle akustično žljaaam žljaaam žljaaam

– istodobno uklj. grijač i kad je voda mlačna, dakle nakon par minuta, čuje se udarac kad se oslobodi spremnik i pada tableta

Općenito, ako krene u “akciju” i zbrejka – tada rade samo gl. pumpa i grijač.

Ako gl. pumpa ima neki meh. problem, dakle zastoj ili teško okretanje rotora uslijed prodora iz smjera turbine (ispred motora), onda prekida jer troši previše struje takav motor i optočna pumpa je krivac. Imate novu, ne znam da li za taj tip, u Batis.hr i cijena je između 500 i 1000 kn, zapišite model pa nazovite
http://batis.hr/perilice.php?id=36&vrsta=22&id2=11

to je velik posao za zamijeniti odnosno 2 h minimalno će vam računati servis.

Ako grijač ima neki problem, onda nema očekivane krivulje rasta temp i zbrejka ciklus.

Grijač – da li uklj. ili ne – najlakše izmjeriti nekom spravom

https://www.chipoteka.hr/artikl/8627…821-6071050011

stavite u utičnicu i pratite potrošnju – odvodna pumpa 30 W cca, elektroventili nekoliko puta 2-3 W, ovisno o broju, glavna pumpa 150 W cca i grijač 1500-2000 W.

Ne znam da li to imate u domu – ali to je najviše pristupačna metoda.

I to bi bilo to – onako školski izrečeno…
