Free Software Alternatives to Adobe CS6

May 14th, 2013

Adobe CS6 Alternatives
Adobe CS6 Alternatives

In 2012 Adobe released CS6. What set this release apart from previous versions was the licensing path that Adobe has chosen. For more information about the Adobe Creative Cloud model, see Adobe’s Creative Cloud FAQ.

While I have been using Photoshop since Photoshop 5, it wasn’t until CS4 was released that I bought my first full Adobe suite. Adobe Design Premium CS4 included:

  • Acrobat 9 Professional – for PDF creation
  • Dreamweaver CS4 – for web site creation
  • Fireworks CS4 – preproduction and mockup for web page creation (combines Dreamweaver and Photoshop features)
  • Flash CS4 Professional – Flash creation
  • Illustrator CS4 – for creating vector graphics and for graphic design
  • InDesign CS4 – for desktop publishing
  • Photoshop CS4 Extended – Photoshop with 3D capabilities

Of the programs that make up the Design Premium suite, Photoshop is where I live and is the application which I am most qualified to comment on. I must say that I have become increasingly disenchanted with Adobe’s approach to the software/graphics market. This has strongly influenced my decision as to whether or not to continue to upgrade my Adobe products. From one review of CS6 we have this summation:

"No creative professional will deny the need for Adobe Creative Suite, and 2012′s version, CS6, focuses on some of the toughest demands designers face in an interactive, digital, multimedia landscape."

From a corporate perspective, that is probably true. Once upon a time you could not get criticized if you bought IBM products. With the advent of the desktop computer, Microsoft became the safe buy. With respect to visual creative software, Adobe holds the corporate safe to buy crown. But I am not a corporation. Nor do I have the deep pockets that would allow me to continue to ride the Adobe Upgrade Train.

So this article is for those who are in search of an alternative to Adobe. For this article, I am only going to look at those alternatives that are free. However, I am not going to do this for every program that is a part of the Design Premium package – just those that I use.

Acrobat 9 Professional

When it comes to creating PDFs, I have never had to make use of the advanced features provided by Acrobat. Instead I have found the capabilities of OpenOffice/LibreOffice Writer’s Export to PDF function to be sufficient for my needs. I will note that Acrobat has come in quite handy when it comes to editing PDFs that I did not create.

If all you need is to create simple PDF versions of documents you’ve created then I suggest using Writer – which is available as a tool in either OpenOffice or LibreOffice.

Dreamweaver CS4

While I have experimented with using Dreamweaver as a web site creation tool, I’ve always had a certain disdain for WYSIWYG web site creation tools. Once upon a time I used NetObjects Fusion professionally. If Microsoft FrontPage was a nightmare, then Fusion was a dream. But I never opted to use Fusion for my personal web sites. I much preferred the hand-coded approach – and still do. As the focus of this article is on graphic software, I will comment no further on Dreamweaver.

Fireworks CS4

Fireworks I’ve used a couple times just to give its web page creation tools a try. As I am not engaged in web design as a full time professional pursuit, I was unwilling to devote time to learning how to use this software, preferring to create quick graphic mockups in Photoshop.

Flash CS4 Professional

I confess that I have never even opened the Flash application. I have never had an interest in using Flash to create digital art and as a web designer have deliberately avoided using Flash for the web sites I’ve done – a strategy that in hindsight appears to have been the right one to follow. So no recommendations here.

Illustrator CS4

I’ve never been much of an Illustrator user so am not really qualified to testify on its strengths and/or weaknesses. All I can say is that it has worked for me when I’ve needed it.

As to free alternative vector software it seems that Inkscape is the most popular option. It is worth noting that Draw, which is another of the software components of both OpenOffice and LibreOffice, is also used to produce vector-based art and diagrams. Draw is the one component of OpenOffice/LibreOffice that I have never used. (Note that my chief reason for migrating from Microsoft Office to OpenOffice was that I viewed OO Impress as a superior product to MS Powerpoint at that point in time). Inkscape is available for the Linux, Mac, and Windows platforms.

Inkscape – inkscape.org

InDesign CS4

My use of InDesign has been minimal. For the most part the documents I create are simple enough in terms of layout that they can be created in OpenOffice/LibreOffice Writer. However, for people who need the capabilities of a desktop publishing (DTP) application then Scribus is worth a look. This free software is available for the Linux, Mac, and Windows platforms. Oh – it is amazingly enough also available for those running OS/2 Warp (my favorite operating system of all time!).

Scribus – http://www.scribus.net/canvas/Scribus

Photoshop CS4 Extended

Photoshop – the software I love to hate due to its frequent crashes and operational glitches. I must say that it seemed to me that each new version of Photoshop crashed more often than the previous version. I was able to eliminate many of the crashes with CS4 by turning off all OpenGL features – which has the unfortunate side effect of reducing Photoshop’s functionality – but I prefer losing features to losing work!

As to free alternatives to Photoshop, there are many. The oldest and most well known of the free alternatives is GIMP. My use of GIMP has been limited but fruitful. My main problem with GIMP is that I would have to learn the GIMP way of doing things. Having used Photoshop for so long, I just know how to do what I want to do without having to think about it. Migrating to new software is always painful in that time must be spent in learning both the GUI and the tools. GIMP is available for the Linux, Mac, and Windows platforms.
GIMP – www.gimp.org

It is not just photographers using Photoshop, but artists as well. Photoshop’s paint brush engine is quite powerful and allows artists to create many painterly effects – serving as a challenge to Corel Painter. One of the free, open source painting software alternatives is Krita. Krita started out as KImageShop, a component of KOffice, a free open source office suite, which was available for Linux, Mac, and Windows. Calligra has apparently stopped development on KOffice (2012) which does not impact Krita. The next version of Krita, 2.7, is expected to be released next month.

Krita is available for Linux and Windows with a beta version available for Mac OS/X. Windows users note that the "highly experimental MSI installer" installs the entire Calligra Suite which includes the applications Words, Stage and Sheets, Flow, Braindump, Karbon and Krita.
Krita – krita.org

Another free open source painting program for artists is MyPaint which is available for the Linux and Windows platforms. What I find appealing is this part of the site’s description of their software: "MyPaint supports pressure or tilt sensitive graphic tablets and comes with an easy-to-use brush collection. There is a complex interface for creating your own brushes, focusing on brush dynamics (changes with speed, pressure, randomly)" Creating my own brushes is one of the Photoshop features that I regularly use so this capability is a must for me.
MyPaint – mypaint.intilinux.com

Adobe Camera Raw

While not listed as a separate product, Adobe Camera Raw (ACR) played a big part in my decision to upgrade from CS to CS4. Adobe did a great job with ACR. In my opinion, it was the best modification made to what was a part of my core work flow as I do a lot of digital photography.

For photographers who are looking for a free alternative to Adobe Camera Raw, one product that is highly rated is RawTherapee which is available for the Linux, Mac, and Windows platforms.

RawTherapee – rawtherapee.com

In Summary

For me, the hardest part of migrating to new software is the loss of knowledge and experience I acquired using my current software. When I started with Photoshop there really were no good alternatives out there. For my money, I prefer to stick with my CS4 software vs upgrading to CS6 or migrating to alternative solutions. However I do anticipate the arrival of a day when I judge some free alternative to my Photoshop CS4 to be of superior quality.

In closing, for artists or photographers who are just starting out and do not have a history of using Adobe products to consider and are not seeking employment that requires a knowledge of Adobe products, this is a great time to investigate the many free software options that are available to you.

Happy Computing, Jim

NSS Roadmap to Space Settlement Student Art Contest

May 2nd, 2013

NASA Moon Base Art

I enjoy judging art contests. I particularly enjoy judging space art contests. I concluded my most recent space art judging experience Monday evening. In this case it was judging the student art that had been submitted to the National Space Society’s Roadmap to Space Settlement Student Art Contest.

The goal of the contest was to get students to create art that could be used to illustrate the NSS Milestones to Space Settlement: An NSS Roadmap – a document that was created for the purpose of laying out for the public the major milestones that will likely have to be passed and the major barriers that will have to be overcome in order for humanity to achieve the NSS vision of "People living and working in thriving communities beyond the Earth and the use of the vast resources of space for the dramatic betterment of humanity." The contest was organized and managed by Lynne Zielinski, the NSS Vice President of Public Affairs (and a member of the Chicago Society for Space Studies).

Unfortunately the contest was run on a very tight time line. The contest was announced on March 25 and the submissions deadline was April 22. Typically art contests provide much more time – both to provide time to promote the contest and to allow artists time to create their submission. However NSS wanted the contest completed in advance of their annual International Space Development Conference (May 23-27).

In spite of the limited time frame the contest received over 300 submissions. Unfortunately the overwhelming majority of these submissions were rejected since they did not meet the contest’s guidelines. Eliminating these non-qualifying submissions left the judges with 14 artworks to evaluate. This was reduced to 13 when it was discovered that one of the submissions was a fraud. The artist claimed to have created his submission using Photoshop and GIMP but the artwork was actually a NASA produced image of a lunar base! I have used that NASA image to illustrate this article. You may have previously seen this image on the NASA or Space.com web sites.

Judging art can be quite challenging at times. However, a well designed set of judging criteria that includes specific elements on which to judge the art helps. For this particular art contest, judges were expected to evaluate the art based on the following elements:

  • the art features one of the milestones listed in the Roadmap to Space Settlement
  • the milestone depicted contains sufficient evidence of accuracy
  • the art is a realistic depiction
  • the art represents more factually based science than fictional science
  • the art uses accurate perspectives
  • the art provides an uplifting, positive message of our future in space
  • the art contains a high level of detail.
  • the art appears to be created in a manner that is consistent with the method described by the artist.
  • all elements of the art appear to be created by the artist

Each judge independently graded each image after which we met to confirm the grand prize winner and to ascertain how many First Prize and Honorable Mention awards would be given out. In the end it was decided to give one First Prize and one Honorable Mention award. The Grand Prize Winner was the entry Asteroid Mining Module and the First Prize Winner was INSPIRE Life – both of which topped my list point wise. An Honorable Mention was awarded to Jupiter Orbital Space Settlement.

It is likely that this contest will be held again next year and, hopefully, I will once again be asked to participate as a judge.

NewSpace Frontier and Astronomy Day

April 15th, 2013

NewSpace Frontier
The NewSpace Frontier

This Saturday is Astronomy Day and once again I will be giving a presentation as a part of the Harper College Astronomy Day activities. The principal sponsor of the event is the Northwest Suburban Astronomers and is cosponsored by the Harper College Department of Physical Sciences. I’m a regular speaker at this event and in recent years have given presentations on The Art of Astronomy, Art and the Exploration of Space, Imaging Mars, and The Universe According to Monty Python.

This year my presentation will be The NewSpace Frontier in which I look at the history of private and commercial space and rocketry activities, the key players today, and the challenges facing this emerging 21st century industry. Of particular concern to me is the possible emergence of an overbearing regulatory environment (ITAR for example). Quoting Patti Grace Smith, former Associate Administrator of the Federal Aviation Administration Office of Commercial Space Transportation: "Don’t over regulate this industry. If we regulate the industry the way certification would require – all the vehicles to be certified, with all the tests and costs – the industry will never get off the ground.". Also of concern is NASA’s willingness to support rather than stifle this new paradigm of space exploration.

Some of the space businesses I’ll be talking about include Armadillo, Bigelow, Deep Space Industries, Golden Spike, Mojave Air and Space Port, Moon Express, NASTAR, Orbital Sciences, Planetary Resources, Reaction Engines, Scaled Composites, Sierra Nevada, Space Adventures, Spaceport America, SpaceX, Virgin Galactic, and XCor.

There will of course be space art in my presentation as space art plays a crucial role in helping people visualize the rockets, spacecraft, space stations, and Moon and Mars bases that the various players envision as a part of our future in space.

As to what hat I’ll be wearing when giving this presentation: while I am a NASA JPL Solar System Ambassador, because I’ll be talking about commercial space and some of the associated politics I can not rightly wear that hat. While billed as a former director of National Space Society for the same presentation which I’m giving a week later at the Winnetka Library, I am not speaking as a representative of National Space Society nor do my views necessarily mirror those of NSS. As President and principal spokesperson for the Chicago Society for Space Studies, I can’t claim to represent the views of that organization. So I’ll be speaking simply as a private citizen who is very interested in seeing our new commercial space enterprises prosper and grow.

In case you can’t attend Astronomy Day, I’ll next be giving my The NewSpace Frontier presentation at the Winnetka Library on Sunday April 28. Details of both events follow.

As to why I care about such things, I offer you the following excerpt from the close of the short story The Sentinel written by Arthur C. Clarke in 1948 and upon which the movie 2001: A Space Odyssey was based:

Perhaps you understand now why that crystal pyramid was set upon the Moon instead of on the Earth. Its builders were not concerned with races still struggling up from savagery. They would be interested in our civilization only if we proved our fitness to survive – by crossing space and so escaping from the Earth, our cradle. That is the challenge that all intelligent races must meet, sooner or later.

Comet Spotting: Pan-STARRS

March 14th, 2013

Comet Pan-STARRS from Schaumburg IL
Comet Pan-STARRS as viewed from Schaumburg IL, 3/13/13

Last night I headed to an artificial hill constructed by the Schaumburg Park District that is probably the highest ground location relative to the surroundings within a 20 minute drive of my home. From that outdoor perch I had hopes of seeing Comet Pan-STARRS.

I was in place observing at about 20 minutes after sunset – about 7:20pm. Pan-STARRS would be setting at 8:18pm so I had one hour to hunt. I had not brought binoculars with me – only my camera. Almost as annoying as the bright sky was the cold. Standing in an exposed position on the top of a hill in 20 degree weather is not my cup of tea.

I looked to the horizon with some trepidation. The combination of haze and horizon glow made for a very bright sky. And street lights in the foreground didn’t help. The only celestial object I could see on the western horizon was the Moon. Below the Moon, nothing. No stars, no Mars – just glow. With a magnitude of 0.9 (the magnitude of Mars is a slightly dimmer 1.2) I has serious doubts as to whether or not I would see Pan-STARRS.

A couple times I thought I detected it using averted vision but in hindsight I think it was unlikely. Over the course of my observing I would periodically take a slightly overexposed photograph to see if I could find Pan-STARRS with my camera. I saw nothing.

Hands numb, I packed up my camera and tripod at 8:15pm and headed home. Popping my camera’s SD card into the computer I was elated to see Comet Pan-STARRS. Once I had the RAW file opened in Photoshop, I duplicated the background layer and set the duplicate layer’s blend mode to multiply. This darkened the sky significantly while leaving the comet’s brightness unchanged – thus greatly increasing the degree of contrast between the comet and the background sky.

A cropped full resolution section of the processed source photograph is used to illustrate this story. You can view the entire photograph here:
Full resolution processed source photograph of Comet Pan-STARRS
In the photo, taken at 7:58pm, you can see just how close Pan-STARRS was to the horizon. The fact that it was almost directly above a street light certainly made it more difficult for my eyes to see it. In the linked photograph, Pan-STARRS as well as a few of the brighter stars are identified with their name appearing slightly above and to the right of the associated object. Here is a link to the star chart I used for identifying the stars in the photograph:
Star chart showing Pan-STARRS on March 13 from Schaumburg IL

Hopefully there will be clear skies this Saturday at Yerkes Observatory and hopefully I’ll be able to find the time to observe Pan-STARRS from that location. The timing will be difficult as I am slated to give a presentation from 7:15 to 7:45pm – prime time for observing Pan-STARRS. Wish me luck.

Ad Astra, Jim

A Day at Yerkes Observatory: Mars and Astronomical Art

March 11th, 2013

Yerkes Observatory
Yerkes Observatory,Williams Bay, WI

This Saturday March 16 I will be participating in both a teacher workshop and a public star party at Yerkes Observatory in Williams Bay WI. This will be my first time visiting Yerkes in a long time. Aside from my duties that day, I hope that I have sufficient time to explore and photograph this landmark observatory.

Packing for Mars Teacher Workshop

Packing for Mars
Packing for Mars

The theme for the teacher workshop I’m taking part in is "Packing for Mars" and uses as its focus the book Packing for Mars: The Curious Science of Life in the Void by Mary Roach (W. W. Norton & Company; 2010). If you are a teacher it is not too late to register. Registration includes CPDUs and lunch. A fee of $25 for the workshop will be collected on the day of the workshop.

The segment that I will be leading, What Would You Bring?, actually deals with planning a human mission to Mars. Identifying the resources a mission would need to bring along is a subset of the overall mission planning. Other aspects of mission planning include mission objectives, mission duration, infrastructure, and strategic and tactical implementation issues.

The planned agenda for the day is:

8:30am Coffee and Registration
9:00am Book Discussion: Packing for Mars
10:00am What Would You Bring?
11:00am Discussion with Mary Roach, author of Packing for Mars
12:00pm Lunch provided by Stars at Yerkes
1:00pm Packing the Portable Life Support System (PLSS)
2:00pm Building Project
4:15pm Wrap up: final thoughts, additional resources, evaluations and CPDUs

To register, complete the Packing for Mars Teacher Workshop Registration Form.

Yerkes Observatory Public Star Party

In the evening there will be a public star party with, hopefully, clear skies. If you do not know what a star party is, it provides people with the opportunity to observe various astronomical wonders using a telescope. For more information, check out the Wikipedia entry for Star Party. As a part of the star party, I will be giving a highly condensed version of my presentation The Art of Astronomy which looks at the evolution of astronomical art over the years.

The star party begins at 7:00pm and ends at 9:00pm. My presentation is about 30 minutes long and will start at 7:15pm. If you plan on attending the Yerkes Observatory Public Star Party, there is a fee of $5 per person or $15 per family. To help the astronomers get an idea of how many people will be attending, please fill out the
Yerkes Observatory Public Star Party Registration Form.

New Art and the Artsnova Web Site Redesign

March 2nd, 2013

Web Site Redesign Before After
Artsnova Web Site Redesign Before (left) and After (right)

Finally after a couple months of somewhat intermittent work I have deployed the redesigned version of my Artsnova Digital Art Gallery web site. One big consequence of the redesign is that I now have a much larger portion of my art online. Prior to the redesign I had 79 artworks on the site. As a part of the redesign I added 117 additional works of art (creating the additional 117 web pages for the art involved more work than the actual redesign!). The art I’ve added spans a number of years – going all the way back to 2002. Much of this is art that I have not previously made available for sale.

I also took this opportunity to remove all the photography from my web site. My plan is to, at some time in the future, create a separate web site for my photography. One site dedicated to art and another site dedicated to photography is a much more appropriate approach from both a business perspective and a search engine optimization perspective. So now I have total of 188 works of art on my site – with yet more to add as I find the time.

Back on the subject of the redesign, my five objectives in redesigning my site were:

  1. to widen the content area to support larger images for the art gallery
  2. to simplify and streamline site navigation
  3. to reduce the number of art gallery subject categories
  4. to give the design a cleaner look primarily by eliminating the sidebar
  5. to prepare the site to be upgraded to a responsive design for mobile browsers.

Widening the Content Area

For me the most important part of the redesign was to widen the content area so that I could use larger images to display my art. In the figure below, you can see a before and after image of one of my artworks – Beyond the Mountains

Beyond the Mountains Gallery Art Before and After

The darkened, desaturated component shows the area of the original image and the larger, colored background image shows the new size. It may not look like much but going from 600 to 670 pixels wide makes for a large difference on smaller screens.

Streamline Site Navigation

The second most conceptually difficult part of the redesign was to simplify site navigation so that I could eliminate an entire category of links. This required a rethinking of how I would organize content – while keeping in mind that the critical factor was making it as easy as possible for visitors to find what they were looking for.

Reduce the Number of Art Galleries

The most difficult part of the redesign was figuring out how to reduce and organize the number of art galleries I had on my site. With the old design, art was organized into the following eight different categories:

  • Abstract Art
  • Astronomical Art
  • Computer Art
  • Moon Art
  • Nature Art
  • Portrait Art
  • Space Art
  • Technology Art

Combining the Moon and Astronomical galleries into a Space gallery was easy. How to handle the abstract, nature, and technology categories proved to be much more difficult. For information about the new galleries and an explanation as to the contents of each, see the Art Gallery Index

A Cleaner Look

Giving the site a cleaner look was easy. Shrink the masthead, eliminate the sidebar, reduce the number of top level site navigation categories from five to four, and reduce the overall page width. The serendipitous aspect of this was that by eliminating a navigation category and the sidebar, I was able to decrease my overall page width while simultaneously expanding the content area.

Responsive Design Preparation

One of my many objectives for the coming year is to create a mobile-friendly version of my web site using what is known as responsive web design. The redesign accomplished this by simplifying the html page structure. This should make it easier for me to code up a responsive design. Stay tuned.

Now for the Bad News

The bad news is that I have not yet modified the template files for this blog so my blog is now not one but two generations of redesign out of sync with my web site. One of these days hopefully I will find the time to go in and redesign my blog so that it matches my web site.

If You Find An Error

If you find an error or mistake on one of the Artsnova pages, please consider dropping me a line. You can use the Artsnova Blog Contact Form to reach me.

Thanks and happy surfing, Jim

Capricon Science Fiction Convention – Artificial Intelligence

February 1st, 2013

Capricon Science Fiction Convention
The Capricon Science Fiction Convention: Artificial Intelligence

I am quite looking forward to next week’s Capricon Science Fiction Convention. The theme for this year’s convention is artificial intelligence, which is an area of computer science that I find fascinating. One aspect of artificial intelligence that interests me is the thought of AIs as the creators of art and music. This would represent a significant advance over today’s generative art approach.

Before getting into a discussion of the panels I hope to attend, I’d like to call attention to the panels I will be on.

Riverworlds: The Latest on Mars and Titan
A panel that I’ll be moderating on the finding of features on Mars and Titan that appear to have been produced by fluvial processes. My copanelists will be a pair of friend of mine: Bill Higgins and Jeffrey Liss.
I Shouldn’t Have Blogged That
Sometimes we speak without thinking – which is bad enough but then your only audience is those folks who are within earshot. But with blogging and social media – we all have the opportunity to look like fools to a huge number of family, friends, and strangers alike. Along with Tracy Lunquist, the panel’s moderator, Kathryn Sullivan and I will talk about how to minimize your risks and how to do damage control.

In addition to participating on two panels, the folks at Capricon graciously offered me the opportunity to do a presentation on my digital art.
The title they picked for my presentation is The Art of Jim Plaxco and has the following description:

Explore the visual possibilities of digital art which uses a variety of techniques using computer graphics software, hardware, and both film and digital photography.

I do like that description because my intent is to focus on what it means to work digitally. I’ll cover hardware, software, work flow, and methodologies and will use some of my own art as examples.

As to the panels I hope to attend, those would be:

AI and the CDC
How the Center for Disease Control is using artificial intelligence.
AI Vision: Early AI vs. Current Technology
A historical overview of human imaginings about AI.
AI’s Impact on Religion and Religion’s Impact on AI
The impact of artificial intelligence on religion and the impact of religion on artificial intelligence.
Boundaries Between Science and Pseudoscience
As a skeptic and proponent of fact-based decision making, this could be quite interesting.
Curiosity on Mars Slideshow
A presentation by my friend and fellow JPL Solar System Ambassador Bill Higgins on the Curiosity rover and what it has uncovered on Mars. Note that Curiosity won the 2012 Crunchie For Best Technology Achievement.
Cylons, Cyberman, and Borg, OH MY! AI Destroys!
Ah yes, the dark side of hi tech.
Do AIs Have Rights?
Perhaps a more interesting question is should all AIs be treated equally?
Dystopias and Why We Love Them
I’ve been on a couple of dystopia panels before and wish I had gotten on this one. It’s a topic that has always fascinated me.
Is Google Making Us Stupid? To the Internet! [Is Google Making Us Stupid?]
I guess I better Google this before providing an answer.
It’s All in the Presentation
A panel for artists that discusses various aspects of the art biz.
NASA/JPL Saturn Mission Lecture
A very cool presentation (I’ve seen earlier versions of it) by friend and fellow JPL Solar System Ambassador John Vittallo about the Cassini mission to Saturn.
Non-Traditional Publishing Options
A look at publishing Ebooks, self-publishing, Amazon, etc.
When Does a Computer Become a Robot?
I would think the answer to this is obvious: when it sprouts arms and legs and is able to fetch.
Writing Nonfiction
A panel for folks who are interested in writing nonfiction.

I’ve listed a lot of panels here but have not checked the program schedule for time conflicts and given my luck I’ll probably actually make less than half of them. I also hope to attend at least some of the convention’s art auction on Saturday night. I still have to decide on whether or not I am going to participate in the convention’s art show.

Reference Links

If you’re attending Capricon, I hope that you are able to find the time to catch my presentation The Art of Jim Plaxco.

Spam Spam Spam Spam Comments

January 8th, 2013

spam spam spam
Spam spam spam spam

A week ago I upgraded my blog’s version of WordPress. A big downside of that upgrade was that a couple of "tricks" I had put in place to defeat the spambots were undone. As a consequence my inbox for moderating comments found itself filled with around a thousand comments. Unwilling to dig through a mountain of garbage I simply deleted everything. If I deleted your comment, my apologies. Earlier today I completed the modifications to my blog that will hopefully make me once more invisible to the spambots. Of course this doesn’t stop those humans low enough to stoop to spamming but that’s a volume I can deal with.

Now one of the goals of a blog is to attract comments but not all comments are created equal. All too many blogs allow spam comments advertising all kinds of garbage to be published. Keeping spammers at bay has led me to pursue several tactics. One that is invisible to the visitor are the WordPress "tricks" I mentioned previously. Another layer of defense is to use a captcha to keep robots out. I use a very simple captcha. While some captchas seem to have as their top priority keeping robots out – at the expense of also keeping people out as well, I’ve gone with a simple captcha that anyone should be able to read – even some bots. Another line of defense is to have moderation turned on. That means that no comment appears on my blog until I approve it (which can unfortunately sometimes lead to significant delays between the time that someone makes a comment and the time I actually approve the comment.) And of course there are always the anti-spam WordPress plugins.

Having had to deal with many comments over the years, based on my experience I have found that comments fall into four broad categories.

Category 1: The Blatant Spam Comment

These comments have nothing to do with the blog post and are simply a commercial directing readers to some web site to buy some product. I’m amazed that this class of comment is so popular because that popularity means that they work often enough to make it worth the spammers time and energy. These spam comments take three forms. First is the url the spammer enters into the address field; second is the link they include in the text of their comment; third is the sales pitch they make in the body of their comment.

Category 2: The Sneaky Spam Comment

These are comments that are little more than a line saying "great post" or "I love your blog" In other words the spammer forgoes the posting of a link and sales pitch in the body of the comment. The spam component is in the url they provide, like loweryourmortgage.dummy (I put in the .dummy part because only a dummy would follow a link like that). The publishing of such comments provides two benefits to the spammer. First there is the chance that someone will be dumb enough to click the link and visit the site. The second benefit is that the link becomes indexed by the search engines and potentially improves the spammer’s search engine ranking.

Category 3: The Generic Comment

The only difference between this comment and the Category 2 Sneaky Spam Comment is the absence of a spam link. I take these short congratulatory comments as directed to me personally rather than as comments that others are meant to read. So while I smile and appreciate receiving these complimentary comments, I do not publish them on my blog because they do not provide original information that benefits the next reader.

Category 4: The Golden Comment

These are the rarest of comments. They are comments that add value to the post. They can be as simple as the asking of a relevant question, or an expansion on what I have written, or a reference to a source of relevant information on another web site. In short these are comments that leave the reader more enlightened.

Conclusion

So if you’re visiting my blog and leave a simple compliment like "nice article", please don’t be surprised if it is never published. While I do appreciate the feedback, I only publish those comments that leave the readers that follow more enlightened about the subject at hand.

Ad Astra, Jim

Goodbye Facebook Fan Page Widget

December 12th, 2012

Artsnova Facebook Fan Page
The Artsnova Facebook Fan Page

As a consequence of a change in Facebook policy I’ve decided to drop the Facebook widget promoting my Facebook Artsnova fan page from my blog’s sidebar. I also plan on changing how I use my Facebook fan page. The policy change that has led me to this course of action was Facebook’s decision to limit how many of a page’s fans actually see the posts in their news feed. This was done so that Facebook can monetize posts. You see you can still reach all your fans – if you are willing to pay for it. This is implemented via the relatively new Facebook Promote option.

With this policy change, unless you pay to promote your posts the reach of your posts is decreased by approximately 85 percent on average. Quoting from the article Paying For Promotion (referenced below):

Dave Seligman, founder of popular geeks culture blog Geeks of Doom told me recently that "Of the 18,000 fans of our Facebook page, only about 900 (5%) of them ever have the opportunity to view one of our posts at a given time."

My Solution

My solution going forward will be to use my Facebook fan page only to post announcements of new posts on my blog. Also, instead of creating short original content posts on Facebook, I will move those posts to my blog. Who knows – perhaps Facebook’s policy change is a good thing for me since it will mean more new content on my own blog rather than on Facebook.

Reference Links

Goodbye Facebook widget. Note that I never liked the way you munged my posts to fit your widget anyway.
