My Bleeding Heart – Secure Blogging & WordPress

April 18, 2014

Summary – By now everyone’s heard about Heartbleed (or should have). As blog writers (& readers), do you understand how that may affect you? Read on…. For photography, follow the link below the image.

 

This is the logo for the Heartbleed bug
Roll your mouse over the image for
Bleeding Hearts (flowers from my garden, that is)

Read here for how I made the out-of-frame flowers


Just a short note about

URL’s (the content of your browser’s address bar)

And – what they have to do with site security

WordPress related sites or otherwise


HTTP vs. HTTPS

Everything I have to say is about the above acronyms

Which, in form or the other, we’ve all seen countless times

Do you know the difference?

HTTP = Hypertext Transfer Protocol

HTTPS = Hypertext Transfer Protocol Secure

The Heartbleed security issue mainly involves the secure version

An error left secure sites not so secure

++++++++++

What does this have to do with me? (or you?)

Did you know that any site can be accessed via

Two separate addresses, for example

http://edkvisions.wordpress.com/

https://edkvisions.wordpress.com/

Identical except for that S for Secure

Click on those both of them

(they’re safe; an old WP blog of mine)

I’ll wait here for you until you return

++++++++++

Did you see any difference?

I hope not! You shouldn’t have

Even though the addresses were different

They’re both accessed & hosted via wordpress.com

as shown at the end of the address

WordPress is certified to be secure (read here)

So – your browser takes you to the https site

With no complaint or cautions

You are at the same site with either address

The sole difference is

Your communication with the site is

Secure (in theory) if accessed via HTTPS

Heartbleed exploits a flaw

In the secure version’s security software

(no problem now with WP’s software by the way)

Not a problem with HTTP (no S)

Since that was never secure to start with

++++++++++

Do you want to see the difference? (safely)

Sure you do (live dangerously; just kidding) ;)

Let’s use my Gallery Blog as an example

http://edknepleygallery.com/

https://edknepleygallery.com/

Once again, I’ll wait until you get back….

OK – A big difference this time, but why

It comes down to something called

A security certificate

My gallery doesn’t have one

The site’s not wordpress.com (that has one as seen above)

It’s edknepleygallery.com

Even though it’s secure there’s no certificate

You only have my word for it

Not an official security authenticating body

The absence of the certificate (sent, or not, from site to browser)

Causes your browser to show you an alert

The alert’s appearance depends on the browser you use

.

Chrome 1st (note what it shows in the address bar)

HTTPS sites often show a locked lock to tell you they’re secure

You’ve seen this with financial transactions most likely

Chrome emphasizes that my site is NOT secure even with HTTPS

and then Firefox (that doesn’t do the URL thingies)

++++++++++

Why did I write this?

A few days ago

I included a link in this blog

To a post in my gallery blog

Something I do often

Somehow (don’t know how)

I linked to the s-version

Which, of course, produced an alert

For any readers who clicked on that link

The same as if you clicked on

https://edknepleygallery.com/ above

Coupled with the current Heartbleed fuss

I spent a few minutes investigating

Decided to share with you

Here’s a great WP-support post on HTTPS

Landscape Themed Exhibit – Any Interest?

April 17, 2014

Summary – The abstract exhibit is over. An entrant suggested a follow-up exhibit: landscapes. How many are interested?


_DSC1461_nx

Smoke Gets In Your Eyes

A Landscape? Yes.  An Intimate Landscape

From a 2007 trip to California – Sequoia National Park


It has been suggested that I host a Landscapes Exhibit

I believe that would draw more entries than

The recently completed Abstracts Exhibit

Possibly more than I’m able to handle

I’m willing to consider it, but with entry limits; maybe as follows

One per person

Deadline in 60 days or

Until 100 entries are received

Whichever comes first

To add to the challenge, the landscapes

Must not include the hand of man (HOM)

Read here if HOM is new to you

Today’s post’s feature image follows this rule

Based on the Abstract Exhibit (where some voting bias was seen)

Entries will be identified initially by a number only

This assumes that after entries close

There will be Equal Merit & Viewers’ Choice selections

 The images should be judged on their own merit

Not who made them or

What clever image title was given


Interest?

Let me know what the interest level is

No’s as well as Yes’s are invited

They tell me something about this blog’s readership


Critique?

If  you chose Yes in the Interest Poll,

Would you like your image “scored” (critiqued)?

Scoring would be based on 0 through 4 in four areas

1. Craftsmanship

2. Composition

3. Creativity

4. Communication

For a perfect score of 16

An image that’s average in all four areas gets an 8

And so on

Each image would be shown with

Four scores (one per area) and a total

And maybe optional comments

 


If there’s enough interest,

I’ll post entry information in a few days

HDR – How it Works & How to Use it Properly

April 16, 2014

Summary – The clearest explanation of how HDR works I’ve seen. Also uses that explanation to demonstrate why many HDR images look so, well HDR-ish (as opposed to natural).

Another great post

by Ming Thein – a good photographer who is

An even better writer

To be expected if you attended Oxford at 16 ;)


I won’t dwell on my feelings about HDR (not all positive)

Ming pretty much says it all

(BUT – if you really want more – here are my 60 HDR posts)

.

Read his excellent article by clicking on this image

(and learn about dynamic range & zone system at the same time

Image Opinions – Judges vs. Viewer Comparisons

April 15, 2014

Summary – Two recent posts showed three judges’ selections for awards as well as the choices of 50 viewers. See how they compare.


Not surprisingly,  judges and “ordinary” viewers

Don’t necessarily have the same tastes when choosing images

Heck – even judges disagree with one another (ditto viewers)

I noted some favoritism in the viewers’ votes – expected I guess

.

Below are examples from the two sets of selections

Eleven selections each by judges and by viewers

1st: Images chosen by both judges & viewers

(These represent 10% of the total entries)

2nd: Chosen only by judges

3rd: Chosen only by viewers

.

There was even one image chosen

Only by a single judge (the most experienced) and zero viewers

 


 xx

The 1st eight hold universal appeal – judges and viewers both

Not so much the following two groups of three

What do you think separates the universal from the others?

Draw your own conclusions and share if you like

In case I didn’t explain things well -

Top 8 + Middle 3 = Equal Merit Selectees

Top 8 + Bottom 3 = Viewers’ Choice Selectees

(Notice how I avoided using the word winner

Everyone is a winner who bothered to enter ;) )

You’ve Gotta’ Hear! – and See!! – This!!!

April 14, 2014

Summary – (Good) Music played in a way that I guarantee you’ve never seen – nor would you believe. 3+ minutes that will make your day.

Don’t be put off by the video’s screen shot below

Trust me, you’ll love the video

What does this have to do with photography?

Nothing.

Take a break ;)
