Insulation Calculations for Geeks

Now and then I search google for an answer to a question and don’t get a  good answer, and this time I’m doing my bit for the greater good to answer these:

“Is it worth putting foam insulation lagging on hot water pipes?”

“Is it worth putting reflective foam insulation around lagged hot water pipes”

“What is the difference in insulation between no pipe-lagging, foam pipe-lagging and foam plus foil lagging?”

Yup, this isn’t about games :D

background: i have a cold old house with a  freezing cellar, and the last occupant did NO insulation. The hot water pipes for the radiators go under the floor in the cellar ceiling, exposed to the cold and damp draughty cellar. A lot of my heating costs were being wasted heating up a damp cellar we never use. So this needed fixing.

Now there is ‘reading books and believing them” and then there is “getting real data”, so I went and got one of these (an infared thermometer £20)

Then I lagged some pipes using that foam insulation stuff, tied on with cable ties. Then as an experiment I doubled up on them by also wrapping that foil stuff you get for the back of radiators around them too, and took measurements. Heres a picture showing all 3 scenarios, where I haven’t finished yet (I ran out of tape…)

With NO lagging, and the radiators on, the temperature of the exposed copper pipes was 57 degrees.

With just tied-on foam insulation, the temperature of the foam was 21 degrees. ( a reduction of 63%ish)

With tied on foam AND a layer of reflective radiator foil, the temperature of the external foil was 12 degrees. (a further reduction of 15%ish)

Obviously the lower the temperature the better, I want all that heat kept in the pipes going to my radiators, not leaking out into the cold air of the cellar.

Conclusion: it is HUGELY worth you lagging any pipes in unused unheated rooms with foam insulation. It is also very worthwhile wrapping the lagged pipes with a  layer of reflective radiator foil. I tape it up with special reflective tape and both the tape and the foil is dirt cheap. The foam tubes are about 50p each.

If you pay heating bills where you live, you would be mad not to do this :D

And if you don’t know where the heat goes, get an infared thermometer. They double up as laser pointers to entertain cats.

AI Spam

Spam is getting cleverer. I deleted some spam from the forums yesterday, and about 100 spam comments this morning form the blog. The thing is, they are becoming more and more cunning. They are contextual spams, that do a passable job of imitating genuine comments from people, albeit confused people with English as their second language.

For example, on my blog post about PC power consumption I got this:

“I don’t have concrete figures, but they should be using very little power with no load attached”

I suspect that the blogspam AI has scanned that post, then gone through a huge database of sentences that contain similar words to words which show up in my post (such as power, load, figures) and pasted in a sample sentence from what is obviously a different, but relevant conversation. All very clever. But two things strike me as not very clever:

1) If you are trying this super advanced AI-spam, try not posting 100 comments in 1 day from the same username on different topics. Thats kind of a big huge giveaway isn’t it?

2) This is a shit way to make money. Do you really think that if you spam a million blogs with pointless comments, enough idiots will follow links in the posters signature to convert to paying customers that make it worthwhile? Do you actually think google are stupid enough to push up your search engine rankings because you get 1,000,000 backlinks from totally irrelevant blogs?

The spammers seem to think that if they send enough spam, and get enough traffic, they will get rich. I think that’s an incredibly naive and scatter-gun approach. I earn enough money, but I don’t get a lot of traffic. The reason my traffic converts into enough sales to pay my bills is because I get relevant traffic. Traffic from people who play PC games, preferably strategy games, ideally (at the moment) sci-fi fans or political gaming fans.

If I look at traffic from ‘stumbleupon’ the site that semi-randomly sends visitors to something roughly in a category they enjoy, it converts at a rate of about $0.01 per visitor. If I get traffic from a PC strategy gaming website the return is up to sixty times higher. Quality not quantity. The 1,000 true fans, and all that. My tip for the people behind new AI spam is to go write some decent AI software for something useful such as natural language processing for customer service support enquiries. You will earn more money and feel better :D

Klingon Christmas Cake

She said I could decorate it “however I wanted“.

Oh rly?

Stage one:

You will need

  • Marzipan
  • Christmas cake
  • Icing
  • Klingon d’k tahg

Stage 2:  Imperial klingon emblem cut out into marzipan and smaller icing using klingon weapon

stage 3: Add some edible gold stars to represent the many star systems of the klingon empire! and tada: A feast fit for a warrior! Qa Plagh!

” batlh Daq joH’a’ Daq the highest, Daq tera’ roj, QaQ DichDaq toward Hoch.”

You might remember me from such festive treats as my klingon pumpkin

Users self-help forums

I have had recent (bad) experiences with this phenomena, but it’s not the first time.

How many times have you gone to a website for a game, a service, an ISP, some software, whatever, and found an ‘official’ self-help forum for users? I seem to recall Dell used to do it, and now almost everyone does it.

“Welcome to the community help forums where fellow member of the ABC community help solve each other’s technical problems”

What this translates (to me) as is this…

“Fuck customer service. We will let you dumb schmucks who bought our stuff fix each others problems. Meanwhile, we are on the beach! Good luck losers…”

I check my forums daily. I don’t post in every thread, and I don’t fix every problem, but I at least flipping TRY to do so. I read every support email I get, and I won’t make you jump through hoops to email a real person. The person is ME. here is my email address: cliff@positech.co.uk.  Here is a clickable one:

cliff@positech.co.uk

Here it is bigger;

cliff@positech.co.uk

I get quite a pile of spam because I am so free with my email address. You know whose problem that is? MINE. Whose problem is it not? My customers.

Fuck email forms, fuck ‘self-help community forums. Fuck “your call is important to us” and definitely fuck “We are experiencing higher than normal traffic“. If you bought a game from me, and it doesn’t run email me. email me now, and I’ll do my best to fix it.

And the next time you encounter a software provider or other company that expects you to not only make do with ‘community’ tech support, but to act as their unpaid helpdesk staff, make a mental note to avoid them in future. Only by hurting the business of people like that will things improve…

And just to add some positivity, who can I name with the same attitude?

Seth Godin, the marketing guy.

BMTMicro, my payment provider,

Cater Allen, the UK bank.

errr….. feel free to add to the list.

Lets talk about patch 28

Ok, so patch 28 for gratuitous space battles is out, bringing the game to version 1.28. Hurrah. Lets take a looky at the two big new things (in addition to the major crash bug that was somehow still in the game, and is hopefully now hunted down and killed).

CUSTOM CHALLENGES

This is a big deal. If you go to the challenges screen, there is a new ‘custom challenge’ map, which opens up a whole new screen showing stuff to fiddle with to basically create your own map, from existing backdrops, plus settings for pilot limits, budget, and the supply limits or spatial anomalies present. You want a battle with a 10,00CR budget, 4 pilots, no shields and no missile modules? You got it kiddo!

You can save out these custom scenarios or load them in, (if you save them out, that lets you name them, otherwise they default to ‘custom map’. Clicking the deploy button takes you to the normal setup screen for arranging your own fleet, and from there you issue a challenge as before. I hope people really investigate this as an option for the game, because it gives a lot more creative control to the player. If you thing fighter rockets are overpowered, you can issue a challenge where there aren’t any, and see what other methods people use to beat you. if you like a certain map but wished it had a ‘must have engines’ requirement, you can do that too. And if I add in extra anomalies or scenario options, they will all end up in this editor too.

MESSAGING

The game now maintains an on-line ‘inbox’ for everyone, and auto-sends you a message when your challenges are beaten or played, or when someone sends you a challenge. It also gives you the option of sending post-challenge feedback to the issuer. This means less wondering how the hell they beat you invincible fleet, and more reading the gloating from your nemesis, which is of course, all in the spirit of GSB.

1.28 took a lot of under-the-hood fiddling, but I think these two things were missing from the game, and needed putting in. I wasn’t sure the challenge stuff would be as popular as I wanted it to be, but it has proved to be very popular, so it’s been l33t to go back and add this stuff to an existing game. The game will auto-update if you have registered it on-line, but I’ll be getting updated patches to the distributors like steam and impulse and the others right away.
