Future Imperfect & Software Stream of Consciousness

Java - determine an image or file exists

One of our programmers asked me how to determine if an image or a file exists last week, so I thought that I would post this code snippet for anyone else that needs a reminder.

String thumbnail = <put the name of image or file here>
try{
File iFile = new File(config.getServletContext().getRealPath("/")
+ "albums/" + thumbnail); //we keep all of our images in a directory called albums

if (iFile.exists()) {
String thisImage = "albums/"+ thumbnail;
} else {
String thisImage = "albums/"+ "noImage.jgp";
}
}
catch (Exception e)
{
System.out.println("Can't find image.");
}

Hope this helps someone.

Musings on Machine Consciousness or Artificial Consciousness

(click on photograph to enlarge)

I was walking along a country road and I came upon this scene picture above. The picture really does no justice to the rolling hils, the lines, folds and textures as well as the light and dark areas. As you eye takes in the panorama in real life, you realize that it is a magical place that makes you feel numinous.

And right in front of me, was a guy with a huge piece of paper, trying to capture the scene with a charcoal sketch in preparation for a painting. The back of his VW stationwagon was lifted open and sketches were scattered all over the car. I peeked at his sketches, and we started talking.

As it turned out, he was from Australia, an ex-computer engineer, a mainframe guy who was now an artist and had been for over 20 years. He earns his living with his art.

We got to talking about stuff, computers and such, and the magnificent scene in front of us, and the impossibility of reproducing and how it made us both feel numinous and from there we got on to consciousness.

I brought up the topic that Ray Kurzweil had predicted a machine with a soul with his book "The Age of A Spiritual Machine". My new-friend begged to differ, citing that we really didn't know what consciousness was, so how could we emulate or even create it on doped silicon.

I wanted to beg to differ with the artist. My own neural nets tell me that consciousness is an over-developed tropism. Plants started it with phototropism for the leaves and geotropism for the roots, and after several hundred million years of evolution gone wild, the tropisms developed into senses, the brain evolved to process the sensory stimuli and it didn't stop. We developed the ability to abstract, to think, and to integrate the sensory data to knowledge and preserve and pass it on to our species.

This got me to thinking about how a primitive artificial consciousness would be formulated in a computer. We already have the prototypes with QoS circuits in servers monitored Quality of Service. We have a heartbeat, plus all sorts of monitors that read and report on processes, cycles, peripherals, services and such. Right now, these QoS circuits report to humans. They would have to report to the machine itself. And the machine would have to react to them.

How it reacts is the tricky part. In humans, we react to our sensory input by abstracting it to a higher plane. If for example, our heart skips a beat, we start worrying about a heart attack. What it means for machine consciousness, is that the data integration into information and finally stringing information into knowledge has to be developed. As a further step, knowledge must be abstracted into an ideal that can be applied to many other things. For example, any child knows the following ideal:

Using this ideal, a child can match the above to this:

And with even a bit of cogitation, a child can match the abstract with this:

So, just to recap to this point, a computer would need sensory inputs from everything about itself, hardware and software, and then it would need some powerful inference tools to sort the Big Data from its sensors into information, and from there in knowledge and from there, into an abstract ideal, or an interface if you will, in programming language.

We haven't touched the world outside the computer yet. But we are not done. Once we have the knowledge bits, we need some emotions bits if we are to match the human experience. I'm not saying that we really need that. The computer conscious could be a Spock-on-steroids who has no emotions, but that wouldn't be fun, would it?

Emotions need qualitative judgements and reactions to those qualitative judgements. In a human being, if we are worried, our performance is impaired. If we were to match this in a machine, worry would spawn threads that would impair performance based on whether the machine was bummed out or not. But how would a machine express happiness? Would it be by innocuous things like playing mp3s when it should be doing floating point co-processing?

My Australian friend said that we would never develop Artificial Consciousness. Moi, I say that what I have brought up are mere details. There will be frameworks upon frameworks that will give the computer a good idea of what is going on, how the computer should react, and that there is a whole other world outside the binary bits and bytes of the doped Gallium Arsenide matrices and PNP and NPN junctions in its transistor neurons. It's a scary thought when a computer first comes to the realization of an outside world, but damn, it would be exciting. More to come.

E-ZPASS Malware Spam

The malware and virus injection spammers are getting more creative, and it has got me to wondering that this isn't originating from Russia. Only Western hackers, and virus scum know about E-ZPass which is the transponder system on interstate highways in North America. Some of the E-ZPass setups photograph your licence plate and send you a bill in the mail. These guy want you to download your invoice. Yeah, right. Here is the email in its comic entiretyl

E-ZPass Collection Agency <refund@sttheresedombivli.org>

Dear customer,

You have not paid for driving on a toll road. This invoice is sent repeatedly,

please service your debt in the shortest possible time.

The invoice can be downloaded here.

There are a couple of ironic and funny things about this piece of malicious spam. First, it is sent from a hacked inactive site of a Catholic girls school run by nuns in Dombivli, India. The school is call St. Therese in Dombivli. Going to the site lights up all of my antivirus protection and Chrome won't go there as well due the virus-laden site. But if you look at the footer of the email, they have an entry call Phishing Policy, and that is exactly what they are doing -- phishing for your private information.

You would think that since this is a Window virus, Microsoft would have solved the virus problem long ago, but they don't have the will to, or Windows is such a piece of crap that it cannot be done.

The "I Quit" Spam Insult Spam

I tell you, the spammers and malware guys are getting more and more entertaining. I recently got a piece of spam that had the subject:

Subject: Can you handle $365 every 100 minutes?

When I looked at the body of the message, it said this:

Hey,

I'm done taking crap from you. I've worked myself to the bone for 8 years now and you don't appreciate a thing I do for you.
You're arrogant, egotistical and you have no loyalty whatsoever. Every time I EVER did anything right, you always took credit for it…and I let you…because I was scared of losing my job.
A true leader takes the blame when things go wrong, and praises the people who did the job when things go right…YOU do it the opposite.

I found someone who takes me seriously:
http://somegoodservice.com/c.php?k=1 blah blah lots of parameters

I don't need you anymore.

Ciao.

See you tonight.
Timothy.

It's hilarious. The URL domain for the link is somegoodservice.com. I didn't bother checking it out, because of lot of sites that inject malware or viruses are legitimate sites. They have been hacked with a weak password and the hackers add a new page that injects malware or viruses. The new page is not seen unless you log in as admin and do a directory listing of all of the directories and look for a file that doesn't belong.

Note the address. They can't decide where they are in Canada or the US with fake street names that don't even make sense.

I hope that nobody falls for this, but I bet that a fair amount are tempted just by sheer curiosity.

The Twegomaniac ~ The Twitter Follower/Unfollower Egomaniacs

My goodness, call me James Audubon and fly me to the moon. I have discovered a new species of bird ~ the Twegomaniac. This was a rare big that is becoming quite common.

The bird is part of fauna that exists in the Twitterverse. There cry is "Follow Me, Follow Me" and to get you to do that, they follow you first. But they are like the cuckoo bird who fools its host. Once you abide by the Twitter netiquette and follow them, they unfollow you. It's all about them. They are the birdbrain egomaniacs who thinks that size matters. They were born with a small size, and to try and enlarge it, instead of having the personality and content to get followers (like Jesus, Ghandi or Clint Eastwood's Empty Chair), they have to resort to trickery. They just don't have the right stuff.

So how do you know if you have come across a Twegomaniac in your follow list? The biggest clue is that you have never heard of them, and they have 100,000 follows and 200,000 followers. The other identifying feature is a big asshole.

So how do you protect yourself from these odious creatures and droppings that they leave all over your home page before they leave. There are a plethora of tools out there to help detect unfollowers. I have been known to use the free aspect of manageflitter.com as a pest control method. There are many more. Beware of the Twegomaniac.

MySQL - Getting a List of Users by who logged in last

I have a list of users. I collect their activity. I want to get a list of users, but I want to order it by who logged in last. Some users haven't logged in in months and don't appear in the login table. There are two tables. One is a users table and the other is a loginTable. The login time is recorded by a timestamp. Here is one way of getting the list and ordering by the last login.

SELECT users.id, MAX(loginTable.timeIn), loginTable.userId FROM loginTable
right join users on loginTable.userId = users.id
ORDER BY MAX(loginTable.timeIn) DESC ;

The right join insures that we get all of the users, even those who don't appear in the loginTable. This is a slow query for a large user table, but since we are collecting metrics it doesn't matter.

Hopes this help someone.

Smart Road JSON or XML Template For Messaging and Data Transmission and Receiving

With the Internet of Everything here among us, and GPS is ubiquitous in vehicles, and cars will have full internet capability, it will not be long before we have Smart Roads. Each road will have an IP address.

I began wondering what the data package would look like for Smart Roads, and then I was struck with the axiom that the best way to predict the future is to invent it.

So without further ado, I cracked together and XML file of what the Smart Road dataset would look like. Here is my first crack at creating a Smart Road Data Standard:

<?xml version="1.0" encoding="UTF-8"?>


<smart_road>

This is just a first iteration. It needs to be tested and validated in real time. It is anticipated that the vehicle will send its GPS coordinates to the database defined by the IP address, and the location specific data will be returned.

Java - How to calculate and find out how many seconds to an event in the future

Java lesson. Let's suppose that you have an event happening in the future. The date and time of that event is stored in a database and you want to calculate how many seconds there are to that event. Once you get seconds, you can divide by 60 to get minutes, and again by 60 to get hours and then by 24 to get days etc.

Here is a code snippet that lets you do that:

Date now = new Date();
Timestamp eventStart = rs.getTimestamp("eventStart");
GregorianCalendar gc = new GregorianCalendar();
gc.setTime(eventStart);
Date endInterval = gc.getTime();
long difference = Math.abs(endInterval.getTime() - now.getTime());
long secondsToEvent = difference / (1000);

Date is java.util.Date. Timestamp is java.sql.Timestamp.

How to find and show line numbers in Wordpad

I had an exception, an error that was being thrown from a compiled .jsp file. Strangely, the console would not give me the line number of the uncompiled jsp, but rather it gave me the line that was causing the exception in the compiled jsp file that was in the work directory.

I didn't feel like opening the file in text editor in Eclipse to locate the line, so I opened the jsp_java file with Wordpad. The trouble is that Wordpad doesn't show line numbers. I found the line numbers in Wordpad with this hack:

1) Select the entire text with Select All (CRTL +A will do it).

2) Expand the bullets menu item and click on the numbered list eg 1. 2. 3. etc

3) Every single new line will now be numbered and you scroll down to the offending line.

Code Snippet for Creating Secure Token in Java

Tokens can be used for many things. Among them are Single Sign On, or saving an identification number without exposing it to the web. Here is a quick code snippet to create a 16 character token

First you need an import:

import java.security.SecureRandom;

here is the code snippet:

String token1 = null;
SecureRandom secureRandom = new SecureRandom();
String secString = new BigInteger(130, secureRandom).toString(32);
token1 = secString.substring(0, 15); //creates a 16 character token

Alter the substring end value to change the size of the token.

Diffusion Without Photoshop Filters

(click on picture for panorama view)

I photographed this bucolic scene in the country, and I knew that because of the dramatic clouds and fields that I was going to make it look like a painting. My normal way of doing this, as an uber geek, is to feed it into Photoshop, and use an array of software filters.

However, it was raining that day, and I had my camera in a ziplock bag. I decided to shoot through the ziplock bag for a diffusion screen. It turned out fantastic. The result is above. It is a great way to get diffusion without Photoshop software image manipulation filters.
