Building a card robot

Today was a very relaxing day, where I tried not to involve myself in any work related stuff at all.

So I asked the kids what they wanted to do this morning. They said, build a robot.

Robots made from construction paper

So we did. Unfortunately, they (the kids) are probably still a little to small to get into Lego Mindstorms or programming and wiring my Raspberry Pi to run some servos, so we went for the next best thing. Cardboard.

robots made from paper

I made some nets (a net here being a 2d diagram for a 3d shape) for the different parts of a robot, we printed them out onto some card, cut them out and stuck them together. The kids decorated the robots with some great creative flair.

It was a great fun day that I would recommend to anyone who finds the weather not suitable for playing outside and want to do something a little different.

Just in case there is anyone else out there in a similar situation I have attached (linked below) the print-outs that we used to build the robot. Cut the solid lines and fold (in most cases) the dotted lines. I printed these onto construction paper and it worked really well. Scoring the to be folded lines using a ball point pen and a ruler is highly recommended to ease making the folds in the right places. A decent quick drying glue is a good idea too – glue sticks just don’t work for this stuff.

card robot legs net card robot head net card robot body net card robot arms net

They look like:

I’ve licensed the the plans/net/images (however you want to refer to them!) under the a very unrestrictive creative commons license so you use them and play around with the safe in knowledge that I’m cool with that.

Although the linked PDF versions are higher quality 🙂 They are designed for printing out onto A4 paper. Although you could/can fit two of the head nets onto one piece of A4 if you fiddle with it.

I hope someone, somewhere, sometime reads this and finds it of use. I know I tried searching the Internet for “robot card net”, “paper robot diagram”, “build your own paper robot” and other such in the hope that someone else had already done the hard work. Perhaps with the magic of Google someone else will search and find this… (if you do, please send me a note, I’d be most happy to find out! 🙂 )

Cheers!

Keeping it real

Anti-Social social media

As many of you who might read this know, I like social media. I spend a reasonable amount of my spare time following and trying to keep up with the information that is available about SAP, cloud and HCM topics. Many of these social media discussions (a majority I’d suggest) take place over twitter. Now recently I’ve found a few tweets that have really got me irritated. But before I explain what got my back up, it’s probably worth pointing out that there is a simple option for me, and it’s put the phone/tablet down and walk away. This really isn’t that serious! Secondly, don’t ask me to name names, I won’t and I don’t think it’s helpful anyway, and I’ll get to why not later.

What’s wrong?

I’ve seen two types of behaviour that I’ve disliked. Firstly has been where people have been using social media as a tool to strike up a conversation. But rather than continuing with the conversation, just make a couple of snide remarks and tried to spark up a fire. In some cases these have been extreme storm in the teapot scenarios, where some information misunderstood, or not at all researched or understood has been used to derive wild scenarios that are great link-bait but do not actually help drive the conversation forward. Conversations are two-sided, if you refuse to engage in a manner that engenders discussion then you don’t have a conversation, you have a battle. In battles the only people that win are the arms manufacturers.

The second type of behaviour is where people represent themselves as “individuals” but start broadcasting what can only be described as advertisements for the products that the company that they work for sells. Now this is a fine line as you’d expect people to be interested in and excited about the products that they company that they work for sells. But when it is done across a whole group of employees and sometimes with a common message/format  then it really starts to smell bad. Even worse when people start tweeting info and then add link to some sales website or their company twitter handle when the content of the tweet isn’t about that! It’s like they are branding their tweets! But when they then refuse to engage on the marketing type tweets to clarify details (possibly because some of the marketing bs is actual bs?) it gets really irritating.

The problem.

Well my real issue is that the response I want to give the tweets of the second type would just make me an asinine tweeter of the first type. Keeping it real and respecting myself involves not walking either of these two paths. And that’s tricky. Not to mention frustrating! This is why I don’t what to name, it’s just behaving like a spoilt brat and isn’t doing anyone any favours. Don’t be evil!

My solution – not “the” solution

I believe that I shouldn’t take myself too seriously, it’s one of the reasons I still keep the ridiculous twitter image that I have whilst pretty much all those that I engage with have sensible portraits. To remind myself not to think overly of my skills, abilities or influence, as I’m just a silly looking guy who’s biggest achievement was becoming a father. Remembering what is important and valuable to me then drives my behaviour. Yes I’ll post this up to vent a little, but the anti-social social media that winds me up, hopefully you won’t see that coming from this direction. 🙂

Seriously, don’t take yourself too seriously. Photo was taken at my son’s 1st birthday party.

Elasticity

 or   or 

(Hooke’s Law for expressing elasticity of an object in various degrees of complexity)

The equations above get pretty complex pretty quickly! And that’s when we deal with equations that have been known about for hundreds of years. When we start using elasticity to describe cloud computing, it gets even worse.

The topic was brought up the other day when I was looking at purchasing some space on the SAP HANA Cloud to run an application that we’re developing in-house. I was checking the price for this.

http://scn.sap.com/thread/3350483

I got quite confused.

Then the conversation moved to twitter and we started discussing not just the price of going to the cloud but also how it should be priced. And then even onto how it could be made multi-tenant (which is a bit beyond the scope of this post, but it was interesting nevertheless.

I think the conversation is worth preserving so I’ve made a copy of it with a little help from Aaron’s Twitter Viewer and a lot of cutting and pasting so I could do without the CSS (if anyone knows how to add custom CSS to a single WordPress post, I’d be interested.)

Have a read, it’s not a bad collection of thoughts, and interjections (by the one and only Dennis H) and I’ll recap on my thoughts at the end:

 My thoughts

A couple of days later and my question has be answered on SCN, but I’ve also had a few moments to think about this.

Drinking your own Champagne

Firstly, to my own need for a productive license to some very minimal use of the SAP HANA Cloud.

With the reasonably low price point that SAP is putting on Cloud Partner status, it certainly seems that they are trying to attract small companies to develop content for them. If you add to this, the “we drink our own champagne” marketing message that has been broadcast very well by the ex-CIO there is a obvious marketing proposition.

If companies that signed on as partners for SAP then submitted an application to the SAP Store for resale, they could be allowed to use it productively themselves, they would have an excellent sales pitch “we drink our own champagne”. A limit on the sizing of the used solution might be in order (but probably wouldn’t be an issue with small companies), but it would be very cool for small companies to do this. It would certainly encourage companies like the one I work for to go the extra step of putting the application into the SAP Store. A win for both the developers and SAP.

Annual fixed storage/cpu isn’t elastic, isn’t cloudy for a PaaS

Probably the clearest idea in the thread above is that PaaS shouldn’t be billed annually. Where we are talking SaaS (like Yariv Zur’s SAP HANA Cloud Portal (which is kinda SaaS and PaaS, but I’d argue definitely both)) then there is a different view, but for a PaaS, the beauty of the solution is in its ability to scale up as demand dictates.

I was talking to BCO6181 – Tony de Thomasis’ uni course this evening about the use case where you have a wonderfully capable server that has 10 CPUs running at 1-2% utilisation all year. And you have a policy that no-one gets a pay rise unless they complete their annual performance review. Guess what, on the afternoon before the cut-off, the system is running at 100% capacity and people are complaining about how slow and poor performing it is. In the cloud you shouldn’t have to deal with that. But if you have to buy your cloud compute units annually, you are going to be in exactly the same space.

On the plus side, it looks as if this might be addressed soon. I really hope so, as I see a big potential for SAP HANA Cloud to be the next big thing in enhancing SAP’s cloud SaaS solutions, but if it’s just a glorified hosting arrangement, then it starts to loose some of that PaaS shine.

Thanks to all those who posted their thoughts publicly for me to capture in this blog. I hope you don’t mind me reposting, let me know if you’d like anything redacted.
