Purple Clover at Sunrise
I took another walk at sunrise recently and took my backup camera, a Canon Rebel XTi and my 70-300 f4.5. I stepped out of the car, took three steps, crouched down and shot this. The clover was still covered in morning dew fog drifted over the ground and the sun was warm and golden.
The early morning and evening hours around sunrise and sunset are best for taking warm, gold-tinted pictures. The sun is less direct and softer, being diffused by the atmosphere, giving a warm honeyed glow to your subject. That’s why experienced photographers refer to the hour after sunrise and before sunset the ‘honeylight’. When shooting pictures like this, it helps to have the sun shining not quite directly behind you.
The sharp foreground and blurry background are created by shooting with the camera lens set to its largest F-stop (in this case 4.5) and a longer exposure which lets in more light and results in what you see here. The clumps of clover in the foreground and background aren’t really as close as they appear in this image. Using a longer lens in this case resulted in creating an image that this was a large field of clover, when in fact it was just a patch of tall grass and weeds.
I got a few more that morning and I’ll post those images when they are ready.
Apple released ProtectMac AntiVirus this month. <sarcasm> Curious, I thought Macintosh computers were immune to malware?</sarcasm>
Apple has been running ads with a guy in a suit representing the PC and another actor in jeans and a t-shirt as a Macintosh. Various commercials show the PC character being paranoid about viruses, Apple even goes so far as to dress the PC actor in a white clean room suit (it’s supposed to look like a biohazard suit). This is supposed to imply that a Macintosh computer is immune to security threats like viruses and malicious websites. It’s not.
Since the dawn of Macintosh Time, the original Macintosh computers used Motorola and later IBM processors, neither of which was compatible with Intel processors. Thus, viruses that ran on a PC with an Intel processor would not run on a Macintosh which used the Motorola or IBM processor. Modern Macintosh computers now use Intel processors, (yes, you can still buy a Macintosh with a non Intel chip) so that myth bit the dust five years ago when Macintosh made the switch to Intel. Further complicating things is Java, which is a virtual environment that renders the actual processor used as meaningless. Java code runs anywhere there is a java engine to run it, which is all current Macintosh computers and PC’s.
Which brings us to the latest Java vulnerability in the Macintosh browser that lets sites hijack the Macintosh and run any command on it they wish, remotely. A security professional, frustrated by Apple not patching this bug even after knowing about it for six months and knowing there was code in the wild to exploit this Macintosh Java vulnerability, released a proof-of-concept piece of Java software to prove the Macintosh could be hacked via Apple’s Java engine. See Computerworld’s article: Angered by Apple delay, hacker posts Mac Java attack code.
CIO magazine’s Ira Winkler felt the hacker releasing the code was a ineffective at best and argued that it’s time for the FTC to investigate Mac Security.
My personal opinion?
I don’t have as big a problem with companies making insecure products, consumers just shouldn’t buy them if they know they are insecure and have a choice. I have a problem with companies misrepresenting products as being secure when they’re not, knowing full well that their consumers are not educated enough to know the difference.
Time Warner announced that AOL will Get the Boot From Time Warner by Year-End. Its about time this merger ended.
Time Warner was built on the broadcast television model: passive viewers force-fed advertising and content of TW’s choice. AOL was built on chat, instant messaging and multi-player games: interactive participants in creating a shared social ‘media experience’ online in real time–that’s what Steve Case used to call “building a community”. AOL and Time Warner had nothing in common, save the prospect of generating ‘shareholder value’ from the merger of the century.
The American Recovery and Reinvestment act has the potential to hammer another nail in the coffin of dial-up ISP’s like AOL. More than $4 billion will be spent to subsidize extension of the communications networks into rural America.
