HERE ARE THE things we learned, loved and shared today.

THINGS WE LEARNED

#GARDA DEATH: The Garda Commissioner, Martin Callinan, has issued a “cry for help” – calling on people who may have information about the murder of Detective Garda Adrian Donohoe to come forward. Taoiseach Enda Kenny has led the tributes to the late Garda, describing his killing as “an outrageous act of cold blooded violence”.

#HORSE BURGERS: Tests on additives used in beef burgers at the Silvercrest Foods plant in Co Monaghan have determined that the source of horse DNA is a meat additive imported from Poland. Silvercrest’s owner, ABP Food Group, says it will change the management at the plant and roll out new testing mechanisms following the discovery, which Simon Coveney says is a “major breakthrough”.

#PROMISSORY NOTES: The ECB has reportedly ruled out Ireland’s hopes of replacing the IBRC promissory notes with a long-term bond – believing the proposal to be in breach of EU treaties. Tánaiste Eamon Gilmore has told the Irish Times, however, that talks on the matter are ongoing and it was his understanding that no final decision had been reached.

#OPINION POLL: A new poll from Red C shows support for Sinn Féin has risen by three percentage points in a fortnight. The Sunday Business Post poll shows Fine Gael has lost one point (to 28) since an equivalent Paddy Power poll two weeks ago, while Labour’s slump continues with a two-point drop to 11.

#ARREST: Gardaí investigating the disappearance of Philip O’Toole have arrested a man in his 40s. The man was arrested in Bray this morning and is being held in the town’s Garda station. The body of a man, thought to be O’Toole, was found in a woodland in Co Wicklow yesterday.

#EGYPT: At least 30 people have died following riots after an Egyptian court handed out 21 death sentences following a disaster at a soccer stadium last year. Police officers are among the deceased following the disturbances at Port Said.

THINGS WE LOVED

• The notion that you could end up getting a cheque for $10 signed by Mark Zuckerberg. Gizmodo reports that the site agreed a settlement with US and Canadian users two months ago after some users found they had ‘Liked’ pages they hadn’t liked. The settlement is split between everyone who asks for it.
• This handy (though, we warn you, coarsely-titled; proceed with caution) handy list of useful websites where you can learn new skills, feed the poor, or just be stimulated.
• This cracking long-exposure photo from AP’s Jens Meyer, showing ski jumper Maxime Laheurte during the provisional competition round at the Nordic Combined FIS World Cup in Klingenthal, Germany:

THINGS WE SHARED

• This Reddit user's imagining of what a Ryan Gosling-Christopher Walken Steve Buscemi (sorry!) lovechild would look like.
• France trying to change the word for 'hashtag'. Okay then.
• Finally, as promised... Parallel parking: like a boss.
