Sorry, the first 36.8% of candidates, you’re out

It’s great that life can be expressed in hard and fast numbers, isn’t it? Whatever would we do if the world were a damn sight more difficult to fathom?

But recently we learnt that the best number of people to have in a meeting is seven. Specifically, that for contestant number 8 and each person thereafter, the group’s effectiveness is reduced by something like 10%. I am as wary of bandying numbers about as you are, so let me just point you at that story: Sorry, Snow White, You’re Out

Now there’s more. Specifically this: don’t hire anybody from the first 36.8% of candidates you interview. Seriously.

America’s National Public Radio (via Lifehacker) describes what’s reportedly known as either the Marriage Problem or the Secretary Problem. It’s a thing. It’s been a thing from sometime in the Stone Age where these two issues were considered to boil down to the same thing: how a man (always a man) should choose the perfect woman (always a girl) for him and nuts to whether she’s got her own sliderule equation about him.

NPR’s story is based on a tale told by author Alex Bellos in The Grapes of Math (UK edition, US edition) – his new and so-gorgeously-titled book that I’m going to buy it right after we’re done.

Alex writes: “Imagine that you are interviewing 20 people to be your secretary [or your spouse or your garage mechanic] with the rule that you must decide at the end of each interview whether or not to give that applicant the job.” If you offer the job to somebody, game’s up. You can’t go on and meet the others. “If you haven’t chosen anyone by the time you see the last candidate, you must offer the job to her,” Alex writes (not assuming that all secretaries are female — he’s just adapting the attitudes of the early ’60s).

So remember: At the end of each interview, you either make an offer or you move on.

If you don’t make an offer, no going back. Once you make an offer, the game stops.

According to Martin Gardner, who in 1960 described the formula (partly worked out earlier by others), the best way to proceed is to interview (or date) the first 36.8 percent of the candidates. Don’t hire (or marry) any of them, but as soon as you meet a candidate who’s better than the best of that first group — that’s the one you choose! Yes, the Very Best Candidate might show up in that first 36.8 percent — in which case you’ll be stuck with second best, but still, if you like favorable odds, this is the best way to go.

It’s easy to mock the way men think there’s logic to dating, so let’s.

But the 36.8% figure has some solid reasoning and also an interesting mathematical history. So do read NPR’s article for more and then do buy Bellos’s book (UK edition, US edition).

How to Learn – by Lewis Carroll

Begin at the beginning, and do not allow yourself to gratify a mere idle curiosity by dipping into the book, here and there. This would very likely lead to your throwing it aside, with the remark “This is much too hard for me!, and thus losing the chance of adding a very large item to your stock of mental delights.

Dial 6 for Murder (and other phone tips)

The downside of having our phones with us all the time is that we have our phones with us all the time. We end up getting calls we don’t want and there are times when we either have to make calls we’d prefer not to – or we are obliged to give out our number. You can’t stop all that but you can make it less of a problem.

Next time you get Unknown Caller and it is another sales call, do whatever you normally do and after you’ve got that out of you system, put their number into your system. Take that moment to add it under the name Spam. And the next one who calls, also Spam.

After a while you will build up this contact called Spam with an awful lot of phone numbers. But it’s surprising how often the same spam numbers call you so while this won’t cure all such calls, you will regularly see the name Spam as Caller ID and can just tap the decline button.

As for making calls, get a burner phone. You’ve seen this in movies: the baddies and/or the goodies who are falsely accused of being baddies and are on the run, they all get burner phones. They’re just another mobile phone that you buy anonymously and you only use for a specific job before throwing them away or planting them on your enemy.

Cheaper and handier than buying new phones all the time, you can just buy an app. Burner is a free iPhone app that gives your phone a new, temporary number. You only get a very limited-use number for free but you can buy new temp ones and delete the old ‘uns at any time.

If you’re thinking that you simply can’t remember the last time you were on the lamb, pursued by the police forces of Illinois and needing to run some interference for the mob, you can also use Burner for eBay. Craigslist, eBay, anything where you need to give out your number to someone but, seriously, you don’t want them phoning you for the next ten years trying to be your buddy.

I don’t get that a lot. But most every woman I know does. For them – or at least for women in the US – here’s my favourite phone trick that will surely, hopefully come to the UK too:

The experience is all-too familiar for many women. An overly aggressive suitor asks for your number. You feel uncomfortable or unsafe, manipulated or just want to end the interaction. Sometimes, it feels easier to hand over your digits than to reject the person outright; but you don’t want to field unwanted text messages or phone calls.

Been there? Over it? Go ahead and memorize this number: (669) 221-6251.

That’s the hotline for the new Feminist Phone Intervention, which automatically replies to calls or text messages from unwelcome admirers with an automatically-generated quote by renowned feminist writer, theorist and professor, bell hooks.

As the anonymous saviors behind the hotline write on Tumblr, “Why give any old fake number, when you can have bell hooks screen your calls?”

This Feminist Hotline Replies To Your ‘Unwanted Suitors’ With A bell hooks Quote – Huffington Post (13 June 2014)

I’m afraid I hadn’t heard of bell hooks. In following that link through to Feminist Phone Intervention, I didn’t learn a lot more but it was a lot more sobering. This is that site’s explanation for why its makers set up the service:

because we’re raised to know it’s safer to give a fake phone number than to directly reject an aggressive guy.
because we’re raised to know that evasion or rejection can be met with violence.
because women are still threatened and punished for rejecting advances.
because (669) UGH-ASIF, WTF-DUDE, and MAJR-SHADE were taken.
because why give any old fake number, when you can have bell hooks screen your calls?
so next time, just give out this number: (669) 221-6251

Sorry, Snow White, you’re out

We’ve had a meeting, us seven dwarves and, I’m sorry, we don’t need you.

Once you’ve got 7 people in a decision-making group, each additional member reduces decision effectiveness by 10%, according to Marcia W. Blenko, Michael C. Mankins, and Paul Rogers, authors of Decide & Deliver: 5 Steps to Breakthrough Performance in Your Organization. Thus, a group of 17 or more rarely makes any decisions.

Find the best online course in anything

I’ve long had a soft spot for Lynda.com and more recently have enjoyed watching some of Screencasts Online’s work. Plus if you’re a member of the Writers’ Guild, the NUJ, Equity or the Musicians’ Guild then you can get free online courses in a huge number of things from the FEU, The Federation of Entertainment Unions and its training site.

But there are more online courses in the world than you can shake your head at and Lifehacker has found a site that helps you find the best one for you.

Online classes are a great way to learn new skills. SlideRule makes your search easier by letting you browse and search through over 17,000 online courses.P

SlideRule’s reach is extensive and covers many popular education providers, like Codecademy, Khan Academy, Udemy, and MIT Open Courseware. You can browse by provider or through subjects like Computers & Technology, Business & Economics, and Law. SlideRule also has a review system so users can rate courses and help you avoid the ones that aren’t worth your time.

In my poking about it, I don’t think the reach is that great: there is a clear bias toward technology subjects. But then Screencasts Online has that too and Lynda.com includes a lot.

But I am keeping an eye on SlideRule; have a look yourself and see what you think.

This is why I buy Macs

You can tell me that PCs are more customisable and I’ll nod but think you a geek. You can tell me that PCs are more powerful and I will take you at your word because you’ve got that kind of face. You can most definitely certainly tell me that PCs are cheaper, there’s no question about that.

But my question is why you’d put yourself through this:

And so I proceeded to install the updates that were available, all 97 of them! I thought I would click to download and install and just leave it running. It stayed on 0% and would not budge. After some digging around I found out that there is a setting turned off by default that can cause this problem so I swiped from the right of the screen, tapped Settings, chose Change PC Settings, tapped Devices and then turned on ‘Download over metered connections’. How did I not spot that immediately? It’s just so obvious…

Anyway, I started to download the updates again and nothing happened until I was greeted with an error code that meant nothing to me. I went to help and support and found out that it meant that other updates were being installed. Well, they were not and I still have not installed one single update.

UPDATE: some new updates appeared which I managed to download, but I now have to provide administrator access to install them. I am logged in as an administrator, but it won’t let me install them because I need to give administrator access despite the fact I am an administrator and that it will not tell me how to do that. For f*cks sake!!!

Swedish government trying six-hour workday

Shudder.

Some government workers in the city of Gothenburg, Sweden, are about to embark on an interesting experiment this summer–a six-hour workday, with full pay.

The year-long project, set to officially begin July 1st, will divide some workers into two groups. One enviable test group will work shorter days, while their colleagues will work eight hours each day. It is unclear how this will be decided exactly, but it is an experiment designed to test growing assumptions that fewer, more-focused hours could be a boon for employee productivity. “We’ll compare the two afterwards and see how they differ,” Mat Pilhem, the Left Party deputy mayor of Gothenburg, told The Local. “We hope to get the staff members taking fewer sick days and feeling better mentally and physically after they’ve worked shorter days.”
