Lame journalism. If they're struggling with spelling of basic surnames like Paczyński, Brzęczyszczykiewicz or Gżegżółka then what will they do if they come across harder ones like Stółzpowyłamywanyminogami or Chrząszczbrzmiwtrzciniewszczebrzeszynie.
It would be nice if the site had an explanation why the decimal 0.1 has no finite representation in base-2 system. In short it's about factorization of the base of the system - base-2 lacks 5 that is present in base-10. It is analogous to 1/3 or 1/7 not having a finite representation in base-10 dot notation of a fraction.
