That was fast.
Oren wins a beer correctly answering the quiz.
Not exactly what I had in mind, but the rules didn't say anything about googling it.

Solution:
MySQL thinks that in my time zone (Jerusalem) daylight savings time starts on March 30th every year (which is not exactly true) and on that day the clock goes from 01:59:59AM straight to 03:00:00AM. So all the datetime values between 30/3 02:00:00 and 30/3 02:59:59 are considered invalid.

Also funny how another person who ran into this thought it was quiz material.

First correct answer to win 1 free beer!(List of beers available upon request)
Post your answer in the comments.

The question:
I am trying to enter the value "30/03/2007 02:15:00" into a datetime column in MySQL and get the error "incorrect datetime".
What's wrong?

*update* Hint #1: format is okay, MySQL knows that 30 is day, 3 is month, 2 is hour and so on.
*update*: Solved! Answer here.

Fine print:
1. The free beer prize is available only within 25 miles of Ramat Gan. No beer-by-mail.
2. Shlomo may not participate.

Zoominfo is a website that exposes a database of companies and people. Zoominfo builds this database automatically by software that crawls the web and extracts structured data from unstructured web pages (for example, "about" pages in company websites and press releases) using natural language processing algorithms.
A while ago, I posted a little satirical "press release" about me, the CTO of pashabitz.com, purchasing a burekas from "sammy burekas".
A couple of weeks ago zoominfo's crawler reached that "press release" and now I am listed as the "chief technology officer of pashabitz.com".

Just a reminder of how hard it is to code anything related to AI.
Computers just can't get a joke.

As I've mentioned, I left Clarizen a couple of months ago.
Now about the new thing:
I joined a new startup company - Semingo.
During the past year I got certain that what I want to do right now is develop ideas "from scratch" in a startup environment. So when Sagie, who is one of the founders of Semingo and my friend from the army days invited me to join - it was a perfect fit.
The idea we're working on is very exciting and the people on the team are very bright.
Oren and Tomer are also blogging from a few feet away (and more bloggers coming soon!!).
We've only just started but it's been a lot of fun already.
About the product: all I can say right now is that it's related to social networks (just because that's what the press release says) and it's as cool as ice (before global warming). Don't worry, we're planning to release soon, so you'll be able to use it in no time (touch wood) - stay tuned!

ASP.NET provides an easy way to write custom http handlers. You simply implement the IHttpHandler interface and register your handler in the "web.config" section under system.web like this:

<httpHandlers>
  <add verb="*" path="*.my_extension" type="MyHanlders.Handler, MyHandlers" />
</httpHandlers>

This registers a class named Handler to handle requests to URLs with extension ".my_extension".
You still need to let the web server know about this extension, and configure it to pass processing of files with this extension to ASP.NET.

To do it in IIS7, add the following to your web.config, under the "configuration" section:

<system.webServer>
  <handlers>
    <add name="handler_name" path="*.my_extension" verb="*" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" />
  </handlers>
</system.webServer>

I couldn't find this all in one place, so, here's how you enable developing and debugging an asp.net app under IIS7 on Vista:

1 Install windows features in "turn windows features on or off". You need these things (which are not installed by default):
Under "web management tools":
a. IIS metabase and IIS 6 configuration compatibility
b. IIS management console
Under "Application Development Features":
a. ASP.NET
Under "Common Http Features" - check everything.



2 Open the web application project in VS, go to proprties, under "Web":
 2.1 Select "Use IIS Web Server".
 2.2 Click "Create Virtual Dir" (this actualy creates an application, not virtual directory on IIS 7).
3 Open IIS manager:
 3.1 Make sure the default web site is started.
 3.2 Select your application:
  3.2.1 Click "basic settings...", choose under "Application Pool" the option "classic .Net AppPool"
  3.2.2 Under "authentication" enable "anonymous authentication"
  3.2.3 If you use windows/forms/passport authentication in your asp.net app. - you need additional configuration.
4 In VS set your startup page (right click on desired page in solution explorer)
5. Run

Note: debugging still shouldn't work at this point, only "start without debug".
Note 2: many places say that you must run VS as administrator (not the default way under Vista), but for me it seems to work when running not as admin as well.

To enable debugging:
1. Install this hotfix. Download here.
Now debugging should work also.

I should've posted on this a while ago, but it's been crazy lately. Better late than never.
A month ago I left my place of work at Clarizen. It's not been long, but it was definitely a great time for me.
I learned a lot and had so much fun.
Most importantly, I had a chance to work with some very talented and wonderful people - Eyal, Eli, Dudu, Sasha, Asher and many many more.
I participated in the development since a relatively early stage in the product's life and seen the release of the public beta.
Do take a look at what came out in the end - www.clarizen.com.

p.s. Clarizen-friends: don't forget to buy me a beer when the IPO comes!!!

Well, that's just the exception to the rule, that only proves the rule. (My Father, when wrong)

A while ago, I complained about how measuring the wrong thing will just make things worse, in particular, how measuring things in software almost never works.
Recently, I read the earth-shattering news that "Transformers" beat the all-time record for first-week revenue by a non-sequel.
"Transformers" beat the all-time record for first-week revenue by a non-sequel.
"Transformers" beat the all-time record for first-week revenue by a non-sequel.
Hmm. Is it, like, good?
Does it mean Transformers is the best thing since (user-generated) sliced bread?
Is it just a sucky flick?
I don't know.
Now, the interesting thing is: how did this ever become the news? Why don't they say "Transformers is the best movie ever", or "John Torturo as a 'section 7' agent is as brilliant as cold fusion"?
And another puzzle, for the advanced reader - why don't you hear about top grossing movies over a year or ten years' period? It's always "first weekend" or "first week".
Here's why:
Movie makers are in it for the money, just like the rest of us. And over the last decade or so, there's this one major obstacle in their little money making business. It's called piracy. It's easier to get an illegal copy of a movie than to get some water from the fridge.
In fact, I'm kind of thirsty now. But I'm not going to get that water. I'm too busy downloading Spiderman 4.
Oh, it's not out yet? No problem. They got it on bittorrent already.
So basically, most money you're going to make on a movie is in the first week or so. After that, everyone has already downloaded it from the internet for free.
Of course, the money people run the movie, not the...hmm...movie people. That's because the money people give the movie people money to buy food, and the movie people, well, they don't give the money people any money.
Now we have money people who run the movie and they want to make some money and they have to do it all in the first week. So they're going to measure, you guessed it, first week revenue.

Why do we care?
Here's the problem - to increase that measurement, which is first week revenue, it is not necessary to make a better movie. You just do better marketing, and more hype, and whatever. Because people who see the movie in the theater during the week don't really get a chance to hear from their friends if it's good or bad. They go because the trailer is really cool, and the ads are everywhere. And so, the quality may or may not suffer. We don't know. Because that's not what we measure.
Here you have an external force (illegal movie copying) creating a random measurement (first week revenue) and potentially driving final product quality down.

And please, don't measure bugs-per-developer either.

I've seen Transformers, by the way. It rocks. Hence my father's quote.

Some things I learned about software while watching Die Hard 4.0 and Transformers:

1. A hacker is most of the times a hot chick.
2. A hacker never uses normal operating systems. They have a bizzare OS, that is specifically optimized for their single need - displaying a map of USA with red dots on it.
3. When a computer is hacked into, the screen flickers.
4. Evil hackers, even if hot chicks, will always be proficient at martial arts as well.
5. You can hack a computer system by directing weird sounds at it.
6. Visualization is king - code breaking and pattern recognition are achieved using quick manipulations of 3D images.
