Big moon tonight? Not bigger than usual
I've seen several comments online saying the moon is going to be huge tonight. The most appeared in the photo sites I visit, telling photographers to go out and enjoy it.
In reality, the moon is no bigger than usual, it just stays near the horizon longer so it appears to be. It's just an illusion.
In any case, it's overcast here so I'll miss it.

Crash Course for Using LINQ
Kevin Goff [MVP] wrote a very good article for beginners in LINQ. If you have not seen LINQ examples yet, or are unclear in what it is and how does it work, Kevin makes it very easy to understand with good examples. Basing on Beta 1 of "Orcas" (the next release of MS Visual Studio), LINQ (Language Integrated Query) comes in four major flavors:
Kevin gives working, easy to follow examples of all four cases.
The article appears in the July/August 2007 issue of Code Magazine and it's available online for subscribers at the link provided above.
Highly recommended article in an excellent magazine to which I subscribe to and urge you to look at if you haven't already done so; (no I do not work for CoDe but I do think they are worth subscribing to).
Querying Microsoft SQL Server data using a strongly-typed DataContext (LINQ to SQL)LINQ puts the power of "objectifying" database access at your fingertips. Sure, you say, but in my organization I do not have access to data-queries as we are required to go through DBA-provided stored procedures only. No problem. You can still use LINQ to DataSets and manipulate the retrieved datasets in your code with ease. This will be very familiar already to developers with experience in Visual FoxPro (I wonder why?).
Querying in-memory .NET objects (LINQ to Objects)
Querying .NET DataSets (LINQ to DataSets)
Querying XML Data (LINQ to XML)

How to photograph fireworks
4th of July is fast approaching and that means Fireworks!
The Photo Guru has good tips on how to photograph fireworks and look like a pro. DPS also has a good tutorial.
Now, get your camera and tripod out there! Here's hoping for clear weather.

Do black holes really exist?
Phil Plait wrote the best explanation of a black hole yet. (Yeah I know, even the name sucks).
He comments on a paper from Case Western Reserve University (PDF), that poises an interesting theoretical question, on how do they even form?
ARS Technica weighs in on the issue too.
He comments on a paper from Case Western Reserve University (PDF), that poises an interesting theoretical question, on how do they even form?
Einstein showed that as gravity increases, your clock runs slower. Literally, if you have two people, one guy up high above a black hole, and another guy close in, the guy outside sees the close-in guy’s clock running slower. Literally, time flows more slowly near an object with gravity, and the stronger the gravity the slower time flows relative to an outside observer. For a black hole, time literally stretches to infinity at the event horizon. Clocks stop. Update: Well, I was being glib. Actually they continue to slow, ever approaching stopping but never actually reaching it. I was trying to simplify, but oversimplified — I make similar comments below in this entry, so where you read that things stop, think of it as "slowing almost to but never quite reaching zero".He explains it more detail in his article, that is a must read (and much easier to comprehend that the scientific paper indicated above.
ARS Technica weighs in on the issue too.
Resharper 3.0 is out!
I was meaning to comment that Resharper 3.0 is out this week but as I have not yet installed it (I'm still at v2.5.2) and other pressing issues, Martin beat me to it.
In any case, it is an excellent tool for Visual Studio 2005 that I wouldn't do without. I have it at home and convinced our company to buy all our development team licenses not to miss on it. If you are wondering, here's their page. Well recommended!

Trust and the USPS website
Allun Jones, Security expert and MS MVP, wrote a 3-part discourse on security (or lack thereof) on the US Postal Service website. He shows the USPS web service for signing up to have your mail held if you are taking off for vacation and will not be home for a while. He shows us how this service teaches us some lessons in privacy and security.
Can't I trust the Postal Service? Part 1 - the crypto
(note that this page shows a problem with their security certificate, since fixed).
Alun's contention is how many people, when presented with a certificate warning would still click on it and go on. Lesson: if you cannot trust the site's security certificate, you should not continue to the web site.
Part 2 - the certificate, talks about inspecting the security certificate, something you should not do unless you are a security researcher and understand what's going on.
In Part 3 - the service Alun finally talks about the service they are providing. You are requesting your mail to be held. You should be required to provide some form of ID to certify that you in fact have the right to do it. You do this when you go to the Post Office in person, right? Why is this important? Try identity theft.
Good series Alun!

Confusing the Czech flag with the "Checkered" flag
Would you confuse the Czech flag with the "Checkered" flag used in car racing?
The city of Islamabad in Pakistan did, posting banners to welcome the Prime Minister of the Czech Republic, but showing the Check flag instead of Czech.

Strobist: Parking Lot Ambush
Strobist shows a clever technique on lighting. Shot on a parking lot, a random-looking photojournalism-type shoot, it was in-fact marvelously choreographed to produce the effect (see photo in the link above). The idea is to use one camera amid a sea of cameras and flashes, but the other cameras act just as props - and light stands - for the wirelessly synchronized flashes.
If you are looking for a setup shot, you already have it. The photo is the setup shot. We used everyone's flash, synchronized to produce a photo that looks random but was in fact very choreographed.Very clever.
We used six flashes for the shot - 3 SB-26's and 3-SB-800s. They were mounted on voice-activate[d] light stands, also known as photographers. There are several tricks to pulling this off. But once you have a roadmap, it is quite easy.
Monterey Pop Festival: 40th Anniversary
This week (June 16-18) is the 40th Anniversary of the Monterey Pop Festival, the outdoor concert in 1967 that started the flower revolution and was part of the Summer of Love.
It was planned by producer Lou Adler and by John and Michelle Phillips of the The Mamas and The Papas.
It featured well known acts as The Byrds, Jefferson Airplane and The Who and introduced unknowns like Janis Joplin and Jimi Hendrix.
The list of performers was awesome:
I was too young and too far away to have attended but it was an amazing concert. (Available on DVD).

The 47 Most Miserable Airports (USA)
U.S. News & World Report has compiled a list of the worst US airports on mayor cities on a variety of issues, including delayed flights and crowded planes.
Chicago's O'Hare (KORD) does not top the list, coming in second. The worst offender is Detroit Metro-Wayne County (KTDW).
My local two airports Miami (KMIA) and Ft. Lauderdale (KFLL) come in too high on the undesirable list too. Miami especially is always crowded, airplanes are full and it is one of the ugliest, most inhospitable of the major airports I've been to. I am pleased to see that my two favorites (and I have traveled quite a bit), Seattle (KSEA) and Washington National (KDCA) are fairly low, which is good.
I guess Detroit must be bad (never been to it) but if the list was made international, London's Heathrow (EGLL) would take the cake.

Are patents stifling innovation?
Timothy Lee has written a very good op-ed piece on software patents in the New York Times. He makes a case against how patents are granted in the USA, saying that companies need copyright protection more than software patent protection.
Witness the case of Verizon vs. Vonage where Vonage used a basic, common sense approach for something obvious, but it was patented by Verizon. This could put them out of business.
(Via ars technica)
"In fact, companies, especially those that are focused on innovation, don’t: software is already protected by copyright law, and there’s no reason any industry needs both types of protection. The rules of copyright are simpler, and protection is available to everyone at very low cost. In contrast, the patent system is cumbersome and expensive."He mentions a memo from Bill Gates to his management team in 1991 warning that the patent race will be detrimental to the software industry but that they should get on board, which they did to protect their legal interests.
Witness the case of Verizon vs. Vonage where Vonage used a basic, common sense approach for something obvious, but it was patented by Verizon. This could put them out of business.
"large companies now hold so many patents that it is almost impossible to create useful software without infringing some of them."What do you think?

Create Advanced Web Applications With Object-Oriented Techniques
Ray Djajadinata has written an excellent article on MSDN Magazine - May 2007 issue, explaining that with the coming of AJAX we learn that the seemingly simple and easy-to-learn JavaScript is not so. AJAX has shown that most of our JavaScript knowledge is incomplete and inadequate. It is not the same world where you could get by with writing simple JS functions for your client-side (browser) code. With the advent of AJAX applications we get very complex JavaScript code.
Ray gives a primer on JavaScrip Object Orientation and how it is OOP, yet it differs from other OOP implementations we may be familiar with (C++, C#, VB.Net, VFP), where you instance objects based on classes. In JavaScript, there are no classes. JavaScript objects are dictionaries.
In our more familiar languages, objects have different properties and methods, based on the classes they are instantiated from. In JavaScript, objects are just collections of name/value pairs, that is a dictionary with string keys.
See for yourself. Excellent article.

Craig S. Boyd on VFP & Vista
Craig S. Boyd [MVP] is back. He posted a blog entry showing off the new stuff he's working on under contract to Microsoft on the "Vista Toolkit" portion of Sedna (the next release of Visual FoxPro).
I have not had much of an opportunity to play with Vista as my home hardware is not up to it and at work we are slow to adopt as all big corporations are.
One thing I liked is his showing off the new Vista dialog windows and how you can leverage them to give your VFP app a more modern look. Even the old Windows MessageBOx() has been deprecated and replaced with an OOP COM object that you can fully control (see Craig's samples).
Good stuff.

eWeek: Gaping Holes Found in IE, Firefox
eWeek reports:
Now we have to wait until Mozilla and Microsoft issue a fix (yet again).
Link
(Via UT)
The researcher, Michal Zalewski, on June 4 reported a JavaScript flaw in fully patched IE 6 and 7 that can allow an attacker to fiddle with a document's Document Object Model—a model for representing HTML or XML and related formats.Mozilla said that this flaw is a duplicate of a previously reported flaw, Bug 381300 "Frame spoofing is possible within a short time frame while the window is loading."
The result can be cookie stealing or cookie resetting, browser crash, page hijacking, code injection or memory corruption.
The vulnerability occurs when JavaScript code instructs the IE application to navigate away from a page that meets same-domain origin policy, Zalewski said...

Not true: you don't use only 10% of your brain
Another urban myth debunked. Massimo Pigliuci points to an article at Snopes.com.
I have heard this crap before. I always understood it to mean that the "unused" 90% was for paranormal development that some people allegedly have. What a bunch of unsubstantiated hooey!
It is of course perpetuated by uncritical media (as mentioned int he article by the likes of Bryant Gumbel and other gullible characters).
The origins of this myth are not clear, but it seems to come from the self-described "psychics" and other con-artists to explain their "gift".

Photo of the Day
I found a woodpecker condo in a dead palm tree not far from my house. There's a couple with one apartment for living quarters, and two more wholes for food storage. They come and go filling it with berries, nuts and occasionally bringing grubs (I suppose there may be chicks inside which I have not seen). This is the male.

40 years ago today, the best album ever, was released
40 years ago, on June 1st, 1967 in the UK (June 2nd in the USA) the Beatles' Sgt. Pepper Lonely Hearts Club Band was released. Arguably the best album ever, it lives on, and I find I like it just as much today as I did at the time.
Do you know who all the people on the cover are?
Hurricane Season starts today
Today, June 1st marks the start of the 2007 Hurricane Season. This is the official start date, although typically the powerful storms don't get here until late July or early August (Andrew, the first named storm in '92 that destroyed Homestead, Florida, came on August 24th).
The State of Florida instituted a 12-day, tax-free holiday on storm items as they do every year.
Here's the NOAA page to track the storms.
Let's hope that whatever comes this way does not reach land or does not do much damage. As always, if you are near the coast or anywhere in Florida, Louisiana or the Carolinas, typical targets, be prepared.
