Great device that iPad

The iPad is a GREAT device! That statement is not going to make this blog among the most controversial you're going to read today.
I've got an iPod touch, and it's as dear to me as my mobile phone. I'd rather not leave home without it. It supplies me with time service (clock), email and feeds, the weather, stocks, my calendar, my contacts, picture album, radio, tv-guide, buzz, twitter and my music. And the games! I browse the App Store, I search, check maps and I Skype. What a device!!!
Then comes the iPad. Automatically I get all the above capabilities and then some. I can now read my paper (a misnomer from now on) in full-size pdf, books, and everything becomes huge and impressive. Even most games written for the iPod touch become larger and easier to play. I'm lost for words. I know for sure it's going to change personal computing fundamentally. You pick it up as if it was a magazine. Then you sit down with it, just about anywhere, the kitchen, tv-room. You can hold it any way you like. Landscape is as natural to it as portrait. You read your mail, you answer some. You check Facebook and Twitter. You update the blog and you put on music and you read the feeds, the paper, etc. Compare this with the way you use or handle your laptop. They really are very different!
It seems only Apple knows how to make these devices. Bill Gates loved tablets for years, but his company failed to make them. He was also unable to get a PC producer to make a decent tablet. Microsoft must be rather upset about how someone else fulfilled their dream, but I don't think they can be blamed. They are a software company. Apple's tablet devices come from a company that has it all. Having just software expertise doesn't mean you have 50% of what it takes to make an iPad, no, you have much, much less. And Microsoft never had what it takes. 

The new app has arrived. It's about Pi, that 3.14 number

It's here now! The Pi-app, not apple Pie, but the numerical Pi.

Extract from the sales-pitch in the App Store:

Are you in Pi? The question is actually: is your birthday in Pi? Is your friend in Pi? Well, let's say you were born June 21 '82. Then enter 62182, or maybe 062182, or 210682 and find out if you're in Pi. You'll know in a second.

π (pronounced pi) is the ratio of a circle's circumference to its diameter. Simple, sure, but π is a mystery!

With this app you can find out if any of the numbers that occur in your life are among the first 1 million (one million) decimal places of Pi, and if so, on what decimal place. Find out if your birthday is there, or your phone number, or postal code, lottery number, salary, etc. Or search for your friends' numbers. Look, look and look up any numbers at any time.

You can also just browse through all the decimals in order to see if you can spot any patterns. Press a button and you get served a page with over 26 000 lines and 38 digits in each. You can copy a few lines and paste into an email.

The new app is late

The new app, which I expected to arrive yesterday or today, is late. I will desist from making another prediction as to the day of arrival. It is however bound to be soon, certainly no more than a few days from now.

NumberWizFP: Solution for the difficult octal sum

The question was: how do you add, subtract, multiply and divide 1, 1, 2, 3, 4, 6 to get 322 octal?


A solution:

322 = (4 + 1) x 3 x (6 + 1) x 2 = 

5 x 3 x 7 x 2 = 17 x 7 x 2 = (10 + 7) x 7 x 2 = (70 + 61) x 2 = 151 x 2

NumberWiz for Diehard Programmers generated this sum and gave the answer in under one second. Why not buy it?

Can't wait for the new app

Seems a long time since we sent the new app to the App Store, but it was only last Monday, Pi-day. The waiting should be about to end soon though. I expect to see it in the store on Monday 21st, surely no later than Tuesday 22nd. In the meantime it's just a matter of preparing the arrival.
Next week will also see an update of NumberWiz for Programmers. It's only a bug-fix.
Don't forget to visit our homepage @ http://proctele.se. There's a Facebook page now too. Guess what: it's called Proctele.

Next app to arrive in a week!

The next app is ready now. We've been testing it in the last few days and it looks like it's free of bugs. We have great hopes for this app. The idea is simple, hence easy to explain. Contrary to the previous app, which was meant for Programmers, this one is for absolutely anyone to enjoy :-) 
The price of the new App will be $0.99.

Happy π-day!

I wish all readers of this blog a Happy and Prosperous π day!

A Great App is soon ready

Proctele's app factory just goes on and on, pumping out one Great App after another:


A new app will be released in the near future. It will be in the App Store in two-three weeks. It is a numerical app and I'm sure it's going to catch on. I hope it will also contribute to increasing the interest in numbers and math.

NumberWizFP hexadecimal example: a solution

The question was:

How do you add, subtract, multiply and divide 2, 3, 4, c, 40, 80 to get f8f ?

One answer is:

f8f = (40 / 2) x (80 - 4) + c + 3 = 20 x 7c + c + 3 = f80 + c + 3

Bored with decimal numbers? Try hexadecimal :-)

Here's one hexadecimal example for NumberWizFp (NumberWiz for Diehard Programmers). It's available on the App Store and easily worth its price.


Add, subtract, multiply and divide 2, 3, 4, c, 40, 80 to make f8f.

Great skiing today

Went skiing with my 5-year old son this morning. Nice conditions, which means loads of snow and not very cold. Felt like skiing in Austria. Conditions have been even better this winter than they were last winter. The site is in for a record length of the season on Wednesday 16 March, which is 100 days, and that's not going to be their last day of the season. Aaah, life is good!

Update for NumberWiz

NumberWiz - the normal version - will be updated soon. 
It solves a bug related to switching from another app back to NumberWiz, a problem I've only observed in iPad.

Show you're a Programmer!

Go to a party, pick up your iPhone and play the iPhone app "NumberWiz for Diehard Programmers". It shows you're a Programmer and proud of it. No further proof is needed!

Update for Elephant Super Memory Challenge is available

The updated "Elephant Super Memory Challenge: Recall This!" has arrived in App Store. The new version is v1.1.
It is now possible to try memorizing the binary digits 0 and 1. This was added to the first screen, the one with letters and digits. 
The button on the lower right now has an additional mode, which is binary digits. The labeling of the button has been made clearer, we hope.

It's official now: Chuck Norris likes our new App

Chuck Norris put the "I Like" stamp on our new app! This is the endorsement I hoped for. 
Chuck Norris looked at the game and said: "YESSS". The iPod melted in awe. 
Chuck commented: If only Steve's company would make as good hardware as those guys at Proctele AB make their software, my carpet wouldn't be filled with molten trash now. Dammit!

The New App is for PROGRAMMERS.

The new app is here and it's for PROGRAMMERS. 
It's called "NumberWiz for Diehard Programmers: Countdown in Octal Hexadecimal and Decimal numberbases". 
In the App Store the name has been shortened to "NumberWiz for Diehard Programmers: Countdown in ...". Hope you Programmers will find it anyway. 
It's only available in English and it's only for iPhone and iPod touch. It's a must-have!
