Every day we read stories concerning the prowess of Russian hackers. But why are they so good? A clue may lie in the fact that Russia has long excelled in maths outreach, which has been instrumental in creating a supply of people with the right skills. More of this later. Meanwhile, here are three puzzles with Russian origins. where x, y, and z are positive whole numbers. 2. Place five stones on an 8x8 grid in such a way that every square consisting of 9 cells has only one stone in it. 3.
Earlier today on my puzzle blog I set you the following puzzles:where x, y, and z are positive whole numbers. Solution Oh my days! Whenever you see 365 in a puzzle, the question is going to be about days of the year. In this question, the equation is asking how many months are there of 28, 30 and 31 days? So, x = 1, y = 4 and z = 7. Extra marks if you worked out that x = 2, y = 1, and z = 9 is the only other solution. In this case there are also 12 months in a year! 2.
Entrepreneurship is challenging in any context. But for Sami Ismail, it’s challenging in a way few others can understand: His company, Intellect Events, which puts on cultural, business, and networking events for entrepreneurs, is based in Damascus, Syria. “We’re living in a war zone,” Ismail says. Ismail, 27, is a veteran of the region’s startup scene, having launched his first company, Findbook, in 2010.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
