VTK Designer has better DICOM imaging support

Nov. 20th, 2009 | 03:11 pm
posted by: [info]prashanthudupa

We have been working on improving medical imaging support in VTK Designer for quite sometime. However, due to heavy workload in other products and projects; this one took a back seat. Up-until now users could select DICOM image set and do a surface render.



But now; over and above this we also support something called "Axial, Coronal and Sagittal plane views". When DICOM images are loaded in this view, you will get...



The DICOM data-file loader in VTK Designer automatically creates the required pipeline, script and configuration form; and embeds it into the right panel. In that form users can view details about the patient and also extract different axial, coronal and sagittal planes by dragging the sliderbars and clicking "Refresh".

We are also working on supporting volume rendering of medical images in VTK Designer.

Logo

I've been writing a stack-oriented variant on Logo that uses postfix notation, kind of a cross between Logo and PostScript:
http://www.tumuski.com/logostack/

It still needs proper documentation, but the examples cover a few basics, and if you're already familiar with Logo, the names of the commands are all very similar. It's just the form that's different.

There's a lot left to do, and I'd like to hear people's thoughts on it.

So I took the plunge. Setting out do something which I could never do in JNNCE. Padhai-likhai

I got into a dual degree consisting of MS in Innovation and Entrepreneurship (2 years) followed by a PhD in Innovation and Entrepreneurship ( 4 years)

A dual degree course there gives me the option to not pay any tuition fees for the duration of the PhD

Apparently they liked my GRE score and I was somehow able to clear the IELTS as well.


There were two questions.
1. How do I study abroad and work - you cant work on a study permit and I didnt want to lose my job ex
2. How do I finance myself?

For that I re-activated my always-standing offer with Nokia Qt (formerly Trolltech) who have agreed to hire me there with timings of my choice. I am to be in a consultative capacity.

I've done the paperwork for the university. As promised Nokia Qt will get me a work permit + residence permit and then I will study in the Norwegian School of Management as a "normal" day scholar.

Running around for the visa now. If all goes well I should be in Oslo and in college and working by Jan 15 :)

Wish me luck,
Take care ya all,
Manish

Mindmap of Cohousing Ideas, Take Two

posted by: [info]zimzat

Okay, let's try this again.

While I was in Tucson, Arizona I stayed at a cohousing community, asked questions, and observed how it all worked. I was invited to listen in on their community meeting, which included budget talks. I made a Mindmap of relevant thoughts and many things I had observed relevant to creating and maintaining a cohousing community. [info]legolastn asked that I post it on LiveJournal. If anyone wants the actual mindmap data file I can look into exporting that as well.

More OOP Woes!

Nov. 16th, 2009 | 12:47 pm
posted by: [info]julisana in [info]php

Thank you so much, [info]nickinuse!!! You solved all my issues this time around!

Hi Guys!

[info]justindustin was so helpful with my last problem and I've made progress with my project, but I'm running into another issue.

Basically, none of my data members can keep their values!

I have two files: index.php and social_media.php. index.php is going to be the data display file, while social_media.php is the class file. index.php has a require_once('social_media.php'), a new Social_Media object, and a call to one of my getter functions in Social_Media.

The object creates just fine. I have some echo statements in my __constructor that display all the data members after they've had values set to them, so I *know* they're set.

Unfortunately, when I go to call my getter function, which includes an echo statement letting me know whether or not the variable has a value, I get a "no value" response.

The getter function is also supposed to pull the value from the database if the value doesn't exists for some reason. But instead of getting the value, it gets me a "Fatal error: Call to a member function prepare() on a non-object" error!

Seriously, what am I doing wrong?

Data members, constructor, and getter code here )

Here are the results that display to my screen right now.

Client ID: 1
Network Name: facebook
Username: my_username
Password: my_password
Profile URL: http://www.facebook.com/my_account

Username doesn't have a value
Fatal error: Call to a member function prepare() on a non-object in /home/julisana/social_media/social_media.php on line 140

getUsername starts on line 123, so line 140 is inside that function.

The more TV I watch with company the more snarky I get at it. Skipping the commercials helps delay that, but it's still bound to happen over time.

I leave Tucson tomorrow afternoon. I've had a relaxing and fun-filled time. I learned to play Killer Bunnies, ate at some new restaurants, and enjoyed the view.

[info]legolastn and his partner are absolutely wonderful people. They're some of the best hosts anyone could ask for. Their community accomodations were open and friendly and it was nice to meet their neighbors. I'm going to miss them. I only wish I hadn't waited so long to try to visit again after the first attempt. Kudos.

Tethering; The simple life

My co-worker would be proud; I'm tethering my phone to my netbook while out of town.

As of this moment I've used 5.87MB down and 895.7kB up. Most of that was just on checking email, facebook, and looking into a couple of pages about cohousing. I didn't even read LJ (I did that from the phone already). :-)

And then I checked all my comics for a Friday. We're now up to 13.71MB down and 1488.8kB up.

Remind me to re-enable 3G next time I do that.

Alrighty, time for me to get in the shower and ready to lounge around, see movies, maybe the zoo, or who knows what. Ahh... the simple life.

I think it's a good sign that I've gotten frazzled.

Yesterday and today I've been working with our client's transaction system since today is a bank holiday. Yet despite the time spent on that, I still attempted to go to the bank today to cash a check.

I need cash for a taxi to the airport tomorrow but unfortunately their ATM wasn't accepting withdrawals either. Oh well, I still have a small stash just for cases like this.

Return of the City State?

Nov. 11th, 2009 | 08:00 am
posted by: [info]natfriedman_rss

A city-state is a city which is also a country, having its own autonomous government.

Ancient Greece had a lot of city states. Hong Kong is a modern city state. China has benefited a lot from Hong Kong, setting up economic “free zones” in several major Chinese cities to emulate the Hong Kong model.

Today our societies are massive tapestries of interdependence. A lot of our infrastructure is naturally centralizing. Noxious coal burning power plants need to be located away from urban centers. Concentrated industrial farming precludes diverse zoning. And TV has homogenized the culture and language of large swaths of the planet.

But distributed energy, farming, and manufacturing technologies are coming. Rooftop solar, small-scale nuclear power, desktop manufacturing, recycling warehouses, high-rise urban farming.

It’s lovely to imagine a new era of independent city states, each with its own cultural and economic values. Each of these cities will be free to experiment with its own way of life, and to discover new and better ways of structuring a society. The Internet has allowed like-minded individuals to find each other and to form cliques, and modern transportation technologies make migration more inexpensive than at any time in human history.

People will assemble in the city states that best fit their own values and dreams, and cities will compete to attract the best people. This has already been happening in the US with its hyper-mobile population. People move to places with specific values like Silicon Valley or Portland or New York. Books like Who’s Your City encourage us to choose our home city based on what kind of person we are. City identity is strengthening.

Cities with different identities have different laws, economic models, and cultures. This is already true today: Gavin Newsom allows gay marriage in San Francisco and Bloomberg bans trans-fats in New York. The question is whether new technologies will make it feasible for cities in the future to have even greater autonomy and freedom to define their own rules of civilization.

Computer Frustration

Nov. 10th, 2009 | 08:53 pm
posted by: [info]natfriedman_rss

58%

That’s the portion of computer experts who report getting helpdesk calls from friends or family at least once a week, according to the survey I ran on twitter the last two weeks.

My survey was not very scientific (163 samples) and definitely has a selection bias (most people who answered use Linux in one way or another, for example, although that doesn’t mean their friends and family do).

But that doesn’t change the fact that 58% is a big chunk of pain.

And a big opportunity for people who want to make computers simpler and more reliable.

How often do family and friends call you about computer problems or to ask how to do something in a particular piece of software?

What sorts of issues prompted computer novices to call their computer-expert friends and family for help? I went through 163 free-form responses in a spreadsheet and tagged them all to find the trends.

Here are the top 15 issues, in order of frequency (percent of issues mentioned):

Skype setup came up surprisingly often; I guess a lot of people are installing it lately. I was distressed to see how common printing issues still are, and curious to note that five different people reported that their friends and family cannot attach files to emails.

About a third of these issues could be addressed by webbook efforts like ChromeOS and litl, although the webbook model will probably raise new issues as well.

It will be interesting to see where Internet/WiFi setup, currently #1 with a bullet, ranks five years from now as the wireless infrastructure matures.

I also asked whether computer frustration has waxed or waned among family and friends over the last five years. There was some disagreement on this.

Based on your personal experience with family and friends, in the last 5 years, would you say the amount of computer frustration people experience has</p>

The top theories for a decline in computer frustration were: increasing skill and comfort with computers (25%), and “they switched to a Mac” (23%). Some people also noted that software quality has improved (13%).

But on the other hand, people are doing much more with their computers, and there are many more computer users.

So your parent who five years ago struggled to do email is now comfortable with email and struggling with online banking or video editing.

Some people also cited an increase in the complexity of computer software.

Computer frustration is not limited to our less-skilled friends and family. Even though 90% of the survey-takers consider themselves either 4/5 or 5/5 on the expertise scale, 32% of them report getting frustrated by their computer at least once a week.

Rate your computer expertise.

Novice                             Expert

How often do you get frustrated trying to do something on your computer?

The list of issues which frustrate experts was more varied and detailed. A few key things came up again and again, however: bugs, bad docs, poor user interfaces, and interoperability/compatibility issues. Not the same as the novice list.

I was hoping to find a strong correlation between operating system use and personal frustration, so I asked people which operating systems they use. They could select multiple operating systems, and 61% of respondents did.

The sample sizes were small, but there was a trend. Here’s the percentage of experts who claim to be frustrated with their computers at least once a week (sample size in parentheses):

I also asked people for their age, and we can make the groundbreaking observation that younger people don’t get frustrated with computers as much as older people, or at least they don’t admit to it. Here’s the percentage of experts who claim to be frustrated with their computers at least once a week:


So what does all this mean?

Mostly I see a huge opportunity. People are so frustrated with computers that products and services that make things simpler and more reliable have a huge market.

Best Buy has figured this out. They don’t break out Geek Squad revenues anymore, but it’s safe to say that they’re pulling in well over a billion dollars a year helping people with their computers (at a healthy 10-20% margin – very decent in Best Buy’s universe).

But that’s just a small piece of the pie. Most people still lean on the nerd in the family. As one commenter on my survey wrote,

Not only am I contacted daily, everybody expects the help that I provide to be free.  Why is it that most people feel that computer people love to work on computers, therefore, they do not mind helping me just this one time for free?  If they experience an electrical issue, or clog their toilet, do they expect the electrician or plumber to fix their problem for free? No they gladly pay them and move on.

That probably won’t last.

Motorcycle Run to Furnace Creek

Nov. 9th, 2009 | 01:51 pm
mood: busy busy
posted by: [info]zimzat

On Saturday several co-workers and other friends went on a motorcycle run to Furnace Creek. The original plan was to Scotty's Castle but at the last minute they decided on a shorter destination. We met up at work then headed out. On the way back we went through Artists Drive up that way; really windy mountain road. Once we got back to Pahrump we decided to split up from there. Some of us still road together until we finally got close to Las Vegas and finally headed separate ways. The route reflects an indication toward my final destination on the north west end of town.

Overall it was a lot of fun. I got to really open up the motorcycle for once. In some cases it was really fun, and others very frightening.

Trying to get the hang of PDO

posted by: [info]julisana in [info]php

Hi Guys!

Lisa's back with her super dumb question time!

I'm trying to get the hang of PDO, and I understand that it'll be easier for my DB Connections in the future, but there are just some (probably basic) things that I'm getting stuck on.

Let's say I have this in my class Click for code snippit )

The goal is to 1) pull the customer's login information for $network out of our database and display it for them on the page (we really try and dumb things down for them), and 2) set $username, $password, and $profile_url, which are data members for my class, with their initial values.

Would the values bound $username, $password, and $profile_url persist after the while loop has ended? Or because of the use of bindColumn, would the values be trashed? Or do I even need the while loop at all? Some of the things I'm reading seem to conflict as to whether or not I need it.

Thanks again!
