Advanced Text Editing In Ubuntu0

Getting stuck on some heavy duty text editing…

A few months ago I finally took the plunge and downloaded and installed Notepad++ (for Windows).

There are plenty of advanced features and plugins available.

I especially like the ability to search for several occurrences of a string of text.

You can count the occurrences, without making changes… or you can mass replace each occurrence.

You can also bookmark every line containing that text.

Once the lines are bookmarked, you can copy all of them to the clipboard, at once… or delete them.

There are many more functions.

I was working on my Ubuntu laptop, and found some files that were quite large.

I almost looked into running Notepad++ on Wine.

I did a search and came up with Scite.

Scite has a similar look and feel to Notepad++.

The text search, count, replacement and bookmarking features are all there.

The only drawback is in the flexibility.

I have not yet found the ability to use plugins with Scite, but I am hoping it is there, somewhere.

You can install Scite from inside of the Ubuntu Software Center, or Synaptic Package Manager.

Playing With Lucid Lynx0

I took some time this weekend to upgrade my main laptop.

I have been running Karmic Koala (Ubuntu 9.10) since it was released.

Lucid Lynx (Ubuntu 10.04) came out on April 29th.

I ran a few system checks prior to the upgrade.

As it turns out… three years of constant pounding on the hard drive had finally taken its toll.

I had a bad sector.

So, I replaced the drive and performed a fresh install.

It boots fast.

With this install, I did notice that fewer items are installed by default.

I was going to use Gimp to edit a photo… and could not find it.

Not really an issue.  I fired up Ubuntu Software Center and installed it.

I do like the change of colors in the default install.  I did not really mind the brown and orange… but the purple is a little more pleasing.

I am getting used to the changes.

Most are minimal and don’t make too much difference, as far as user adjustment goes.

You can download Lucid Lynx here.

Finding Images0

Someone posed a question to me.

“Without becoming an expert photographer, how do I find images to use for general purposes?”

I scratched my head.

I have come across some postings of free images in the past… but all the web addresses, I have lost.

I heard someone say, not too long ago…

‘When I need an image, I just go do a search… then right-click and save the image… then use it in whatever I want.’

The only problem with that is… copyright laws.

Many, if not most, of the classic images that we come across on a regular basis are copyrighted.

That includes photos, paintings, (Adobe) Photoshopped illustrations, etc.

For example, that picture of Marilyn Monroe or Elvis that you want to include in a post or presentation, somewhere…

Chances are, it’s copyrighted.

Legally, you should not use it, without contacting the owner for rights or permissions to do so.

Image drawn by:  batux / hyoga

I came across OpenClipArt.org.

From what I have been able to gather, the images are submitted as public domain.

(Disclaimer:  You will want to read and understand the different licenses, including items in the public domain, before using any images.)

A Visual Breakdown On Viruses & Malware0

The Deal with computer-threats
Via: Online Schools

A Checksum Head-scratcher0

I have a ‘high maintenance’ friend that constantly needs help with their computer.

About every 4 months, they manage to get some sort of unknown malignancy.

It happened again.

So, for a ’small fee’ I am re-installing Windows XP on their machine.

I went through the regular gyrations, the list of things that I normally install.

Everything seemed to be going fine…

I did notice an oddity I have never experienced before.

Deep into the installation, I kept getting errors… checksum and corrupt files.

The errors occurred after downloading files from a browser.

I did a great deal of research.

Using google as my main tool, I found the problem was described…

But I never could find a descriptive solution.

I finally stumbled across a reference to a similar problem.

The solution suggested was to use the validation for Windows Genuine Advantage.

I tried it.

I was in a weird situation.

I had to update Internet Explorer to use WGA, but the errors would not let me update.

Catch 22!

An extra two hours out…

I finally decided to use a restore point, (that was just after the fresh install) and install all of the Windows Updates, and ensure that WGA was in the list.

After about another 45 minutes out of the way…

I had Windows Updates functioning.

After a reboot…

Downloads were functioning… and the file corruption and checksum errors were gone.

Looks like the culprit was a corruption with something dealing with WGA and the download process.

Got to love Windows Genuine Advantage.

And I feel so much better, now that I know that Windows on my friend’s machine is a legitimate, legal copy.

Playing With Cron0

For kicks, lately… I have been trying to get a handle on cron.

If you need more information, check out this explanation.

In simplistic terms… if you want to automate a computer task… cron is a good way to do it.

And, there is loads of documentation on it, out there.

I came across this… the cron sandbox.

If you want to play with your schedule options in cron…

You type in the parameters for your schedule, for the job.

Click the Run button, and the sandbox creates a list, telling you when your job will execute.

Cron comes with most versions of Linux, BSD and Mac OS X.

If you want a version for Windows, check out cronw here.

A Strange Error In Ubuntu0

I was running my Update Manager in Ubuntu, Karmic Koala, over the weekend.

I was faced with:

(Reading database … 75% dpkg: unrecoverable fatal error, aborting:
failed in buffer_read(fd): files list for package `XYZ-package’: Input/output error
E: Sub-process /usr/bin/dpkg returned an error code (2)

For the past couple of days…

I have been searching forums, blogs and help sites.

I found several postings that suggested running an assortment of commands.

I tried them, but to no avail.

One post in a forum suggested that it would be necessary to re-install Ubuntu.

(That was pretty much NOT going to happen. There HAD to be an easier way.)

Then, I found a website that suggested the following commands:

sudo mv /var/lib/dpkg/status /var/lib/dpkg/status.bad
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status

I tried them… but still, no help.

The ‘Reading database… ‘ portion of the display kept freezing at 75%.

Then, I got a brainstorm.

I pulled up /var/lib/dpkg/status in gedit.

I searched for ‘XYZ-package’.

I found two references, within the status file.

I selected both blocks of text, describing ‘XYZ-package’ and deleted them both.

I ran

sudo apt-get update
sudo apt-get autoremove

I then ran Update Manager, and it ran with no problems!

I am glad that I stuck to my guns, and kept looking beyond the suggestion to re-install.

Like Windows, Ubuntu and other variants of Linux have their Total Cost of Ownership…

But I would much rather spend a little time doing research… than having to re-install my OS every few months.

Bloating and Statistics0

After perusing an article at Ars Technica, about piracy estimates and losses

Any time you hear someone quoting statistics, remember…

92 % of all statistics are completely useless!

It’s not that I am against watching trends and analyzing data.

I like to look at reports and graphs, as much as the next person.

It reminds me of some interesting stories over the years.

Without citing names…

Several hacker stories come to mind.

When you talk about damages being done… whether intentional or coincidental…

It seems that the intention of accuracy gets thrown out the window.

Is it because the dramatic gives way to leverage and planning… and helps someone state their cause?

I would imagine… or… I would guess.

I will say, that whenever I hear the term ‘estimates’ and it used with statistics…

I always question the accuracy or validity of the statement being made.

If you hear someone in a business estimating ‘losses,’ you are taking the person’s account and report on faith and trust.

Most of the time, unless you see the business owner, writing a check and handing it over to someone…

Or calling a third party to negotiate some sort of repairs…

You could question the extent of damages in any situation.

It seems inherent in human nature that we dramatize and emphasize.

In discussing losses, many times that behavior is positively reinforced.

I can remember stories of a hacker logging in to a publicly open wi-fi network… owned by a private company.

When all they do is look around.. and get off, within five minutes…

It does not seem like they have a whole lot of time to do much damage.

But… it seems that in those situations, you always hear stories of how that single event costs that company between $500,000 and $1,000,000 in damages.

Many times… the damage estimates include buying equipment and software to make sure the event does not happen again.

(In other words, “We had no clue what we were doing when we set this up. We did not know you had to secure it!“)

So… if they needed to buy the equipment, anyway… is it really considered damage?

Moving An Old Windows Install To New Hardware0

I have an old Compaq workstation, loaded with Windows XP.

It’s in the back room.

I have some software installed on it, that was a nightmare to configure.

It took me a long time, and a great deal of heartache.

Recently, the machine has begun to freeze at a black screen.

No blue screen, no error messages, just freezing.

Seeing that the machine is about 8 years old…

I dug through my resources, and found a newer P4. Not really all that new, but better than the Compaq.

It’s completely different hardware.

I was not about to re-install everything.

I made up my mind.

I WOULD find a way to get the image from the old Compaq working on the newer P4.

I used clonezilla and made an image copy.

I copied the image to the hard drive from the Compaq and put it on the P4.

When I rebooted, I got INACCESSIBLE_BOOT_DEVICE (the dreaded BSOD).

After a quick Google search… I came across an article here.

I followed the instructions, carefully.

Fifteen minutes later, the P4 was up and running, with the image from the Compaq!

Things I would add to the instructions…

Boot into Safe Mode, first.

Gather your network card drivers and video drivers, ahead of time.

Once you get the machine booted into a full, regular boot, take and install the drivers.

Once you get the network card driver installed, it will be easier to get the rest of the drivers to install.

The considerations I gained from this:

The two main differences in Windows installs, on different hardware, are usually video and IDE drivers.

If you can revert those drivers to the ‘plain vanilla’ Windows native, you may be able to get the image to boot without the help of the article.

So… ultimately… it is entirely possible to copy a complete install from one machine to another and get it to work, even though the hardware is different.

Mobile Ads And Search0

Not too long ago, Steve Jobs and Eric Schmidt were seen sitting at a cafe in Palo Alto, CA.

While people are scratching their heads at what the topic of conversation was…

There is much competition going on, there.

Google bought AdMob, not too long ago.

That’s to help their continued endeavor into the mobile market.

Apple has also purchased a mobile-based ad company.

According to Steve Jobs, desktop search is very lucrative.

As for mobile search, people just are not using it the same as they would a desktop.

What’s in it for the future?

According to some reports, mobile advertising will continue to grow.

Of course, these projections will hold true, if all things are considered equal.

Adding, of course, that nothing major happens to change the mobile hardware market over the next few years.

Some projections have mobile advertising doubling, between 2013 and 2014.

It’s good to see continued competition between players.

In my opinion, right now, smart phones and internet mobility are somewhat luxuries.

Not everyone can afford an iPhone or smart phone… or the plan.

In order for the mobile markets to become really lucrative…

Mobility has to be attainable by the masses.

More people on, means more people to reach in advertising.

That could account for the massive ad revenues related to desktop search.

Taking The Printer Concept To New Levels0

Over the past 30 years, or so… computer printers have come a long way.

That’s from the old thermal and dot matrix types, as well as other antiquated types.

Recently, some innovative people have thought deeply about the printing concept.

Not too long ago, I saw a design for a prototype of a building printer.

Imagine, if you wanted a house… and you input the dimensions.

Once it is finished… you have a fully finished, and functional home.

The one I saw was only a design, and I am not sure how far the idea has progressed or matured.

There is an article on Reuters, regarding another concept, utilizing the same printer concept.

This one is designed for skin cells.

Imagine, getting a burn on your arm.

You hold your arm under the ‘printer’ and the unit sprays new skin cells over the exposed area.

The design is just that, for now.

The designers have plans to pursue the full development process.

It sounds promising, but is a little ways away from FDA approval for testing.

I liked the demonstration and the innovation of this.

Setback For Net Neutrality0

Over the past couple of years, we have heard various arguments on Net Neutrality.

On one side, it seems as if internet providers may do whatever they wish with traffic, traversing their network

One could argue, that if they offer VOIP or phone service… they could, in practice, disable free VOIP applications.

That’s in hope that you will get frustrated and buy their VOIP service.

On the other side of the argument… You have the free and open internet.

To have any government or entity step in, and start regulating it… would detract from the internet economy.

Many see any regulation as a step in the wrong direction.

The things that make the internet a great environment, might cease to function.

That’s a simple explanation.

Today, The U.S. Court of Appeals in Washington, D.C. ruled that the FCC lacks authority to regulate the internet.

Early on… I was convinced that there needed to be regulation to help ‘the little guy.’

Recently, my feelings have changed.

In an open and free internet, without regulation, economies and innovation will thrive.

Boundaries are made to be broken.

Limitations are often an exercise that makes invention thrive.

With the government becoming more and more involved in our economy…

I am relieved to hear that the internet will still be open and free.

That’s free from regulation, free from tax and free from red tape.

According to some reports, the next move for the FCC, if they really want to pursue regulation…

Is to re-classify cable providers as communications companies.

It will be interesting to watch how all that unfolds.

Protecting Your Information On Facebook0

In the past few months, we have begun to realize the downside of social media.

Sharing information is a great and wonderful thing…

But many people ignore the most important aspect.

That aspect is, you are sharing information!

That in itself is not necessarily a bad thing…

But the audience composition can not be ignored.

It’s been revealed that many government agencies, local and national level scan Facebook.

Potential employers scan Facebook and MySpace for prospective candidates, to get a picture of their personality, and profile.

The downside to that is… the more information you reveal, the more chances you have to reveal something subjectively undesirable, from an employer’s standpoint.

I would doubt that the list of entities using the social media data is limited to those.

So… it might be pretty easy to get an idea of your habits, from a subjective standpoint.

The other thing that everyone potentially could forget…

There are also undesirable types searching social media for information.

They might use it to steal your identity, stalk you or burglarize your home.

What can you do?

PCWorld has a great article on steps you may take to help protect your privacy.

Create Diagrams With Free Software0

I had someone ask me about software for creating a flowchart.

Dia is a great, free software package for different types of charts.

There are shapes available for regular flowcharts, for engineering, electical, chemical and several other categories.

Dia is free and open source. It is available for Windows and Linux.

You can download it here.

The Evolution Of The Consumer0

I came across a great article at PC World.

For the computer literate, as well as the illiterate.

There are plenty of things that we take for granted, when it comes to our computers, and technology.

If you think about it, in detail… it’s probably enough to drive you insane.

The fact is… any time you have interaction with technology…

When you introduce the convenience of the advantages… you inherently also introduce disadvantages.

We have our computers, printers, cell phones, mp3 players and we have an assortment of service and utility providers.

In most cases, we have the providers we easily realize and acknowledge.

We know we have cable, cell and internet providers.

As we continue to evolve as consumers, we also gain new advantages and disadvantages.

How much information does your online music or book store keep about you?

As we continue to do more business online, we continue to engage new challenges in privacy and electronic rights.

The article above is a great read… and I hope it gives you a new perspective and awareness, as an individual and consumer.

Enhance Your Presentations With Zoomit0

I had someone ask about something to use for presentations.

Zoomit is a great tool from SysInternals.

Zoomit allows you to zoom in on parts of the screen and annotate it.

It’s good for presentations, but has some other uses.

The keys can be customized… by default, CTRL-1 turns the zoom feature on.

CTRL-2 allows you to draw or annotate.

You can also type on the screen, as well as set timer features to temporarily disable the screensaver.

You can download Zoomit here.

Updating Your Resumé0

Recently, I helped a couple of friends with their resumé.

It’s a good idea for all of us to keep ours updated.

When you look over your resumé, look for talents that you may have left off.

Many times, I have seen a resumé  get overlooked, simply because of things left out.

The goal is to describe your qualifications and experience, and initiate interest.

All too often, a poorly written resumé can cause a candidate to become overlooked.

A resume that ‘overdoes it,’ can also create bias.

“Strong management skills,” is a better phrase to use, than, “a good manager.”

Describing competence is a good quality, but be careful about going too far.

If you are looking for a particular IT job, you can list that particular position in your objective.

I have found it is much better to use a description of your experience and give yourself a more flexible title.

“Self-motivated, problem solver seeking challenges,” could give you more notice than “System Administrator with five years of experience.”

When it comes to listing your experiences, don’t short yourself.

Try to look at the big picture, and make observances about your job history, accordingly.

I have seen people use phrases, like “running reports” and, “reading reports.”

When I spoke with them in greater detail, I found that they had more experience in trending and analysis than those simple phrases implied.

There are a few myths, too.

No one wants to read a bloated novel, but it is a myth that a resumé has to be limited to one page.

You should include enough detail to cover your job history and experience, and whet the appetite of the viewer.

I have seen people attempt to squeeze all of their information and experience into one page, and the result was too hard to read.

One page is probably too short… but two pages as a limit is a good rule of thumb.

Describing awards and honors can be a toss-up.

In my opinion, a person is better off describing the circumstances that led to the award or honor.

If you received an award for leadership, describe your leadership abilities, or project management skills.

I usually try to avoid egocentric references.  Be careful of sounding like a brag.

I find that many times, those can be dismissed by a subjective judge.

“I am the best leader,” is probably not quite as effective as, “Managing multiple projects, simultaneously.”

As with anything we do, we have to bring balance into the picture.

The best balance on a resumé, is to recognize and highlight talents, while maintaining a humble quality.

A Different Kind of Electronic Box0


Printing Directories0

Seems like a regular basis, that I have to print a directory for some reason.

Usually, I pull up a command line.

In Windows…

c:\Documents and Settings\joe m\> dir >listing.txt

That usually does the job.

You can open listing.txt in notepad or a word processor.

I came across Karen’s Directory Printer.

It’s a fantastic little tool.

Helps avoid the extra steps I mentioned before.

The program is free to use.

(Make sure you read the full license agreement.)

The Safest Search Engine0

Mcafee has named AOL Search as the safest search engine.

(I was surprised to hear that.)

The study by Mcafee also found that searches for digital music is also risky.

The number of search results returned when a user searches for digital music indicate that about 20 % of the results may be infected with some sort of malware or virus.

That’s even more risky that searching for porn.

The study found that a porn search returns about 10 % of unwanted results.

Also found questionable… searches for screensavers and wallpaper.

The most dangerous searches, found in the study are searching on celebrity names.

In some instances, such searches return 35 and 40 % of infectious sites.

With regular search engine activity, you should always keep your scanners for virus and malware up to date.

If you can, set up the scans and updates to happen, automatically.

If not… make it a regular practice to scan your machine on a regular basis.

After you finish on your machine, for the day… take the time to start a virus scan, and walk away.

Check back, periodically, until it finishes.

For malware and adware, repeat the practice.

Every time you surf and search, is a good frequency to use for your scans.

A Simple Explanation of Binary0


I came across this video at csunplugged.com.

This is a fantastic site.

It offers teachings in a format, aimed at kids.

But…

There is plenty of information that will benefit adults.

More Nasty Stuff Via Email0

Facebook users beware…

Another virus is out to steal your FB credentials… and who knows what else?

An email that is being sent to FB users, via regular internet email accounts, prompts users to change their password.

A link is being attached and passed through the email.

When the user clicks the link, viruses and / or malware are being downloaded and installed on the users’ machines.

An estimated 400 million people across the world use Facebook.

10 % of those are expected to be subject to the infection.

That’s roughly 40 million user accounts.

It’s a reminder, that you should run your scans frequently.

That includes viruses, malware and rootkit scans.

If you can, set the scans to run when you are away from your computer.

Once a day is a good frequency.

Also… change your Facebook password, if you haven’t already.

Make sure that you go to a browser to change it… and do not click the link through email.

Remember, when you are running Windows, clicking a simple unknown link through email can unleash all sorts of nastiness on your machine.

A New Kind Of Hack0

Police in Austin, Texas, have arrested a 20 year-old in connection with several car ‘mishaps.’

As it turns out…

About a hundred car problems were reported, simultaneosly.

Problems ranged from horns honking, reported to be at night, to the ignition being deactivated.

The High Tech Crime Unit was activated.

The common factor in all of the cases?

The cars were all purchased from the same dealer.

As it turns out, the dealership had a vendor that had remote access to the cars.

The system was designed to be used in the event of deliquent payments by the consumer.

Since the reported perpetrator had access to the website password…

Authorities say that he used the password to disable cars, honk horns and annoy buyers from the dealership.

The interesting part… this was done, remotely!

The vendor offers the service as an alternative to repossession.

The person arrested was a former employee of the dealership.

From a personal point of view… I think this raises several questions.

The buyers / owners that were affected… how has this inconvenienced them?

Is this a sign of things to come?

Imagine an appliance in your home that ceases to function, because of a missed payment… or a mistake.

I am not sure that this will be a welcomed or embraced tactic.

The article describes the cars as “bricked,” which implies to me that many were completely disabled.

I am also not sure if there is any hope of them becoming functional, again.

Send Free Faxes With FaxZero1

If you have found yourself having to send a fax… you know it can be a pain.

Who wants to have a fax machine in their home, these days?

Sure…  you can get an all-in-one device.

But… if you are not so fortunate… there are other options.

I came across FaxZero.

The service is free, but there are limitations. You are allowed two faxes per day, and there is a 3 page limit.

There is also an ad that is printed on the destination cover page.

There is a paid service, available through the site, with less limitations.

Not bad, for the user who has light fax needs.

Test Your Connection Speed With Help From Uncle Sam0

The government wants users to have a clear picture of their broadband connection.

The FCC has released a tool / site to help consumers realize their connection speed.

www.broadband.gov

I am not sure where this might go, from here.

Many consumers have been complaining of speeds lagging behind what the ISPs have been advertising.

Some even reported lagging by as much as 50%, during high usage hours.

The government is also collecting information on areas that have no broadband connection.

Google Gets More Social In News0

I love Digg.

Now, Google is getting into the social news game.

The format is somewhat different from Digg.

Will it steal any traffic from Digg?

It’s hard to say.

I can tell you… that even though I like Digg… it’s not my only source of newsfeeds.

It’s a complement to all of the feeds I use.

I am guessing that everyone will use Reader Play in the same way that I would.

I do like the format, of one item at a time, with the selection bar at the bottom.

Nerves & Presentations0

I came across an article on Psychology Today, How to give a presentation Part I.

Some good stuff in the post.

At one point in my life…

I had to give presentations… and teach others.

While preparation is the biggest part of teaching or presenting…

The truth is… the best presentations you will ever give, are on topics that are within your grasp, or your expertise.

I have been thrown into the position of having to give a presentation on subject matter with which I had no idea.

I always tried to avoid those scenarios.

That often involved scenarios in which I had no access to anyone with any expertise on the subject.

So… I had to develop my research skills.

Now, I understand enough about my own preparation needs, that I have a better procedure in place, should I present anything.

After clearing the hurdle of knowledge and understanding…

There is still the one last piece.

All of us experience butterflies or nerves.

For many of us… it becomes a matter of a few seconds in which we find our groove and the session begins to flow.

For some of us… the process takes a little longer.

There is a trick to it.

After spending a great deal of time, doing presentations…

I walked away with the best understanding of ‘the trick.’

When you speak to a group, large or small, you are trying to process all of the images of the people looking back at you.

Trying to ’speak to the whole group,’ you may overload your senses.

(By unknown practice, we let our eyes dart, all over the place.)

Many times, this overload will stumble your expressions and your vocal output.

‘The trick’ is to meet the eyes of the individuals in your audience… SLOWLY.

Pick individuals throughout the audience, and look at them, for a few seconds.

Don’t let your eyes jump around, randomly.

The best way to do this, is, as you speak; pick a person on the front row and complete a sentence to them.

Gradually let your eyes drift over and back a few feet, to another person in the audience.

Meet their eyes, and complete the next sentence directly to them.

Continue the process, but avoid the tendency to let your eyes just jump around.

Make and maintain eye contact, complete a sentence, then move to the next listener.

Many times, this will take practice… which you can do in meetings, or face to face with others.

I also may raise my voice, at times, to overcome nerves.

What I found is… through preparation, controlled eye contact and voice control…

My preparations improved quite a bit… and I was finally able to ward off and minimize the effect of nerves.

(And that is according to feedback from others.)

Buck Rogers Comes Back From The Future0

This is part of a series of web released episodes of Buck Rogers.

See if you recognize the actors playing the parents.

A Graphical Display For Google Suggest0

I was surfing around this evening… and came across whatdoyousuggest.net.

It uses Google Suggest, but puts it in a graphical format.

Google Suggest… Remember it?

When you type in the text box on the main page for Google Search…

You see the listing from Google Suggest, pop up under the text box.


whatdoyousuggest offers an easy-to-use interace.

As you click on the nodes, on the right, sub branches expand with more selections.

When you click on a selection on the right, the URL listing is displayed on the left.
