Надія Воловодівська про необхідність запровадження електронного голосування

Tut, v L'vovi dijut'sja jakis' paskudni reczi. Na smitnykah, tak, pid derevom (в районі вул. Перфецького. - О.П.),  ljudy poznahodyly zapovmneni b'juletni, des', v inszych miscjach, - pusti. Poky szczo ne czuty ni pojasnen' vid vlady, ni vid tyh, hto jszov na vybory. Des' i naszi zapovneni b'juletni moz'ut' valjatys'. Jak by te pytannja postavyty ruba - pro elektronne holosuvannja? Poky ne bude tak, szczo jak ljudy holosujut', tak i budut' vybrani deputaty, v suspil'stvi ne bude ni doviry do vlady, ni spokoju.

Перевиборчі польові маневри львівської влади

Чув, що на хутір Збиранку відважна маршрутка 1003 почала ходити щопівгодини. Це щось у лісі здохло. Досі возили пасажирів, як до Майданка, всупереч всім правилам гідного поводження з людьми. Вибори, вибори... Що ж це буде після них?...Та все ж, не зважаючи навіть на необхідність сякого-такого підлещування до мешканців Львова та його збиранських околиць, дорога в районі Голосківського цвинтаря і дач з незапам'ятних часів в страшенній руїні, автомобільний транспорт губить у яругах-вибоях всі діючі і запасні частини.
Чув також, що напередодні виборів тепло почали прикручувати лише наполовину. Як в тій пісні: половину місяця, половину сонця. Ніби так можна вирішити проблему, якої насправді ніхто вирішувати і не збирається.

Про енергетичний безлад у Львові та околицях

"Укр. правда" написала, що з 1.09.2015 р. Україна розпочала експорт електрики до Польщі (буцім-то раніше того не було). Нічого не маю проти. Але одночасно у Львові почали ввечері вимикати світло, а вдень тепло (одне з другим тісно пов'язані). Як в тій пісні про Ріо-де-Жанейро. Питається, а ми що не люди? Щодо тепла, то його можна регулювати не таким варварським способом, а поставивши регулюючі крани безпосередньо перед входом на батареї, зробивши не послідовне, а паралельне під'єднання батарей. Так, як це є в усіх цивілізований країнах, напр. Естонії і Польщі. Дрібниця, але вдарила б по совковій корупції. Але на жаль, геноцид проти власного народу (в даному випадку проти львів'ян) продовжується...

Репліка на заголовок допису в "Укр. правді""

Сумнівно, чи українська, "Укр. правда" іронічно пише, що "Турчинов хоче захистити Україну від агресора ракетним щитом". На мою думку, пан Турчинов висловив прагнення всіх Українців.

Відгук на допис в "Укр. правді" "Чи був сепаратизм в журналі "Соціологія"? Коментарі соціологів"

 То не тільки редакція цього журналу, а вся верхівка НАНУ скурвлена. А також дирекції багатьох академічних установ і вузів. Серед них маса прихованих комуністів і антиукраїнців, які жалкують за старими часами. Всіх їх давно треба пустити з торбами по світу, провести очищення української науки і освіти. Інакше міситимемо совкове, постімперіальне болото ще не один десяток літ.
