Big Data, Data, Data Science, Knowledge

Whilst looking into some suitable questions to ask about Big Data, I can across an excellent poster titled “Do you know Big Data?” produced by Altamira.

The poster covers a set of questions that help you question Big Data and a Big Data project.

  • What is Big Data?
  • What types of Big Data are there?
  • How do we extract knowledge from Big Data?
  • What do we do with knowledge we extract?
  • What types of Visual Techniques are there?
  • What types of Statistical Algorithms are there?
  • How big is Big Data?
  • What is a Data Scientist?
  • How do we implement Big Data solutions?
  • How do we address privacy and ethics in Big Data?
  • How do we secure Big Data?
  • What are leading Big Data tools?
  • What questions should we ask about Databases?
  • What questions about Predictive Tools?

Open Source, Open Human, Open Data, Open Sesame!

30 Monday Mar 2015

Cloud, Data, IoT, Open Source, Wearable Tech

Opeopenn Source is a term that is now common place  meaning access to the inner workings of a thing to allow a wider community of people to help develop and take it forward. A good example of this is in software. The Internet is full of Open Source Software projects that people are developing and collaborating on, sharing data.

A project by the Personal Genome Project is now looking to take the idea of Open Source to the next level with Open Humans. The project is looking for volunteers to Open Source themselves and publicly share data about their health to further science and medical fields. The project does state though that you can choose what data you share.

Open Data is a term relating to data that can be shared openly and freely. An example of this are the data sets freely available by governments such as Data.gov and Data.gov.uk.

By 2020 it is predicted that with a world population of 7.6 billion, there will be 50 billion connected devices. That’s 6.58 connected devices per person. Some people have that now with phones, tablets, wrist devices, glasses etc. Each device capable of producing a lot of data on usage, actions, etc. How much of this data will be private vs open is yet to be determined and the ability to opt in and out need to be clearer for people to understand.

A report in todays BBC News claims that yet more personal data is being sold illegally. This time pensions data (Pension data ‘sales’ investigated by watchdog) . However as we take more steps towards the IoT (Internet of Things) are we able to keep track of our data and how it is used or are we heading towards an Open Sesame bonanza of data treasure being opened, taken and sold on.

Open Sesame is a magical phrase used by Ali Baba to access a secret cave of treasure. In this case the treasure is data!

Professional vs Personal Social Media

26 Thursday Mar 2015

GTD, Productivity, Social Media

Having read an article from HBR on “How to Separate the Personal and Professional on Social Media” I decided to look at the Social Media tool I often use and in what part of my Professional and Personal life they fall.

Working on from my Personal Knowledge Management System there are a couple of others shown in the diagram. This is just my quick classification of SMT (Social Media Tools) – everyone else may have a different view such as Facebook for business to reach consumers in particular markets. However it is worth looking if you class the tools as Professional or Personal. A few do sit in the middle for me as they have a place on both sides of the page.

Some of the tools are clearly for Professional use, but some do step either way across the line.

One potential way of keeping things apart is multiple accounts on a platform, one personal and one professional, but it is important to understand and set some guidelines on how you use these.

SocialPP

If you are communicating on Social Media representing an employer, always check their policy on Social Media and communications.

If you don’t have any, there are a number of good rules available.  Kevan Lee has done some research into these and had come up with a list of 29 Social Media Rules

For all social networks

1. Share several times a day, but space out your posts every few hours.

2. Respond to all comments as quickly as you can.

3. Know the art of the hashtag. 1 hashtag is fine. 10 hashtags are not.

4. Always keep the 80/20 rule! Entertain and inform your audience first, sell to them second.

5. Use first person plural when talking about your company brand (We, Us).

For Twitter

6. Don’t automatically direct message people that follow you.

7. Don’t use all 140 characters. Give people room to retweet with a reply.

8. Don’t hijack another company’s hashtag.

9. Don’t buy followers.

10. Don’t stuff your tweets with keywords.

For Facebook

11. Don’t Like your own post.

12. Don’t post or tag photos of fans, customers, or employees without permission.

13. Don’t tag people or pages that aren’t relevant to your post.

14. Don’t ask for Likes, Comments, or Shares.

LinkedIn

15. Personalize your connection requests. Tell them WHY you’re connecting.

16. Once connected, send a “welcome” message.

17. Don’t join groups and immediately start selling yourself.

18. Don’t ignore the more professional tone of the network.

Google+

19. Always +mention users when commenting on their posts.

20. When sharing a post, always add your own commentary to it first.

21. Share to Circles to target your content.

22. Use Google+ formatting for your text—bold, italics, and strikethrough.

Pinterest

23. Don’t neglect to provide good descriptions for your pins.

24. Always link back to the original source and give credit.

25. Don’t use images that have nothing to do with your clickthrough content to get more pins or clicks.

26. Don’t pin just your own material.

Instagram

27. Don’t ask people to follow you or use hashtags like #tagsforlikes – it’s unprofessional.

28. Don’t overgram. No one likes their feed filled up with one user.

29. Use hashtags for your brand appropriately. The golden number of hashtags is 11.

– Kevan Lee (https://blog.bufferapp.com/social-media-rules-etiquette)

Social Media seems to have taken the theory of Six Degrees of Separation and in some cases turned it into One or Two Degrees of Separation!

Lunch? No I’ve got a meeting!

19 Thursday Mar 2015

GTD, Productivity

A recent study from the University of Toronto looked at Restorative Lunch Breaks and the effect of having a good relaxing lunch break on employees.

The study found that relaxing activities during lunch, freely-chosen by workers, led to the least amount of reported fatigue at the end of the day.  Getting work done resulted in employees appearing more tired, but that effect was reduced when employees felt it was their decision.Socializing, however, also led to higher levels of fatigue; something the paper says has to do with whether workers feel free to decide if they want to socialize and who they’re socializing with.

Bupa state that “UK companies are losing close to £50 million a day in lost productivity as workers fail to take a lunch break”.

Bupa also point out that the levels of productivity plummet in the afternoon if no lunch break is taken. A similar finding to the University of Toronto.

The UK Government state that “Workers have the right to one uninterrupted 20 minute rest break during their working day (this could be a tea or lunch break), if they work more than 6 hours a day.” But how many workers are actually doing this?

To get around this I have block booked a whole year of Lunch Breaks in my diary to try and reclaim sometime around Lunch to disengage and get away from the keyboard. An ambitious move! time will tell if it works. The challenge to this approach though is that people booking slots into your diary do not often use the booking tools to identify a free/busy time and book it because they are free at that time.

Race to the largest Raspberry Pi Cluster

Architecture, Cloud, IoT, Programming

The humble Raspberry Pi has been around for some time and its popularity is growing again with the latest release of the Pi and is a great development platform for the Internet of Things both cost wise and its sheer versatility from basic programming and running Minecraft, to hosting a Docker server.

GCHQ have recently announced the clustering of a 66 node Pi cluster called bramble. They have just pipped the University of Southampton who built a 64 node Pi cluster out of the Pi and Lego.

Some other earlier attempts have seen a 32 Node Cluster Beowulf from the Boise State University.

However it would appear that a 120 node Cluster is currently being developed.

With the 32 node cluster costing roughly the same as a PC, this technology has certainly brought high powered computing into the reach of most people today and the applications going forward are huge for development of solutions.

Lists – Are we addicted to them?

11 Wednesday Mar 2015

Posted by Max Hemingway in Social Media

Social Media

Maybe its me but there seems to be an increase in the use of Lists in both inside and outside of the work place. Social Media is full of them such as:

  • 14 Reasons to like….
  • 6 things you didn’t know about…..
  • 50 ways to…..

Businesses are also using this format internally to publish key information to their employees.

Lists (known as Listicles) are everywhere and ever popular as a way of getting information across to an audience. Listicles have been used for a long time in Magazines and now very common in all forms of media.

In journalism and blogging, a listicle is a short-form of writing that uses a list as its thematic structure, but is fleshed out with sufficient copy to be published as an article.

– Wikipedia

Why are they so popular?

  • They get a message across in the title
  • Quickly distil information
  • Popular form of getting the message across
  • Quick to read
  • Easy to write (no additional context needed)
  • Attract readers

So are there any dangers to lists? Readers are drawn into lists on Social Media which have been published with the sole reason of filling your screen with adverts. Known as Clickbait. We are so use to seeing lists and utilising them that we often click to read with no thought about where the link is taking us to.

There is some good advice on list writing that is often in the form of another list. The main key to a good list is the topic and the content.

Like them or hate them, lists have been around for a long time and will still be here for around for the foreseeable future.
