What are the 4 types of computer maintenance?

  1. Over time, your system builds up temp files that need to be cleared out. Specialized software exists to take care of this task.
  2. Keeping your OS up-to-date is very important. The OS is never "finished", what you get as an OS is simply the best, least buggy version of the OS at the scheduled release date. So, update and patches are regarded a normal in the life cycle of software.
  3. Rather than running the various programs manually, the OS has built in mechanisms that allow the user to schedule tasks to automatically run at predetermined times or based on action triggers, such as loggin in or shutting down.
  4. Lastly, there are some fixes that solve the problem better than 50% of the time. It's one of the simplests, most idiotic, and successful fixes that solves many problems: Cycling the power on the machine.

    Some will say that cycling the power is a noobs call to action, however, shutting down the computer, and unpluggin it for 3-4 minutes is a good first step towards solving your issue. 😏

Monthly computer maintenance

  • scan for rootkit using your anti-virus software
  • check for updates for OS and Apps
  • run system cleaner
  • verify backups are being stored correctly by recovering some data
  • blow dust out of the computer case. Dusty environments can overheat a CPU and graphics card very quicky if it's not removed on a regular basis.

Current operating system updates

  • always run OS sytem updates they become available. This will prevent opportunistic viruses from accessing your computer.

Computer maintenance schedule

  • Assign system tasks to take care of the routine tasks that need to be performed.

Regular computer maintenance

The fail safe quick fix is to "shut off" the computer and unplug it from the wall for 3 minutes. As dumb as this sounds, for the basic quick fix, try this and see if it works. Obviously, this won't work for every situation, but it's a first goto fix for most problems.

Strong Passwords that are Easy to Remember

Strong Passwords that are Easy to Remember

Passwords are the worst. They are difficult to remember, difficult to create and difficult to diffrentiate between sites.


Most current password systems will require the following:
  • Between 8-12, sometimes 16, characters
  • A number 0-9
  • A capital letter A-Z
  • A lower case letter a-z
  • A punctuation mark !@# (recommended confining to these only)

Complex Passwords

The easiest way to create passwords is to use a system to build unique passwords that are easy to remember. The easiest way is to take two characters from the domain, a year, a punctuation mark, and a key word, and combind them together into a phrase that is almost the same for every site, yet slightly different.

Different Passwords

We also want each password for each website to be unique, so that if one site is hacked then your user name and password for the hacked site can’t be used to gain access to your accounts on different sites.

Strong Passwords

The way to do this is to build a password phrase, such as below:

Domain2 char Domain KeyYearPunc.5+ char Key WordNew Combo Password
FIRSTsecondFIRSTsecond Year Punc Key-word
FIRSTlastFIRSTlast Key-word Year Punc

Probe Lens, what is it?

According the the New Oxford American Dictionary, to “probe” means to “physically explore or examine (something) with the hands or an instrument”. In the same text, a “probe” is a “blunt-ended surgical instrument used for exploring a wound or part of the body” or rather a “a small device, especially an electrode, used for measuring, testing, or obtaining information”. A probe lens may then be aptly defined as “a lens used to physically explore or examine something”. Probe lenses; therefore, have existed for centuries in the form of telescopes, or microscopes. If one were to venture further back in history, one might describe the “reading stones” invented in the 13th century used by monks to illuminate manuscripts as a form of probe lens. Perhaps too, the magnifying glasses invented in the 10th century were probe lenses, much like the reading glasses that rest on the bridge of one’s nose. Not every lens is a probe lens. Some lenses are used for decoration, for example, the lenses that are part of a chandelier. In the film and video industry, perhaps every lens is a probe lens. A lens is used to explore or examine the behavior of monkeys in the Congo in a documentary. A lens is used to explore or examine the artistic expression of our deepest ideas in a narrative motion picture. Perhaps the definition needs to be expanded. Perhaps, a manufacturer, in the film and video industry, of the 21st century, where thousands of lenses exist, must qualify a lens as a probe lens, because to probe is a very helpful concept to market the unique set of characteristics that combine to form the Venus Optics Laowa 24mm f14 EF Cine-Mod Lens.

Microsoft to ends support for Internet Explorer on June 15, 2022

Microsoft to ends support for Internet Explorer on June 15, 2022

(Reuters) - Microsoft Corp is pulling the plug on its once omnipresent browser, Internet Explorer, next year as it prepares to battle market leader Chrome with its slicker Edge browser.

Launched in 1995, Internet Explorer became the dominant browser for over a decade as it was bundled with Microsoft's Windows operating system that came pre-installed in billions of computers.

The browser, however, started losing out to Google's Chrome in the late 2000s and has become a subject of countless internet memes for its sluggishness in comparison to its rivals.

To compete better, Microsoft launched the Edge browser in 2015 that runs on the same technology as the Google browser.

As of April, Chrome has a 65% share of the global browser market, followed by Apple Inc's Safari, with an 18% share, according to web analytics firm Statcounter. Microsoft Edge has a 3% share, while Internet Explorer has a miniscule share of the market it once dominated.

The Windows software maker said on Wednesday the future of Internet Explorer on Windows 10 was in its faster and more secure Microsoft Edge.

"Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022, for certain versions of Windows 10," the company said in a blog post. (https://bit.ly/341JvuE)

The browser was at the heart of an antitrust case against Microsoft more than two decades ago, with a U.S. judge deciding that the software titan had broken the law after it combined Internet Explorer and the Windows operating system.

The most serious violations of the law were upheld on appeal, but the company continued to bundle its operating system and browser.

This software is one of the most impressive amateur projects that I have seen. The reason for this is that I was attempting to build the same software some time ago. Presenta is a much better, better coded version of my same idea. It\'s uncanny that Francisco\'s Presenta is so close to what I was envisioning.

The idea behind Presenta is a quick, easy to create slideshow/presentation player.

Based on the markdown format, as the base human readable format, the user can easily piece together text, links, images, and video within minutes, which can be easily shared across the internet.

The presentations are divided into blocks similar to the markdown file\'s "---\"

You need a monitor upgrade, now – 4K UHD

Recently, GME paid off in a bountiful way.  In celebration, I purchased an upgrade for my computer: a newer, larger, higher resolution monitor, and I have to say that it's the best purchase that I have made in a while.

Due to my current eyesight, the monitor has really enhanced my ability to effectively use my computer.

Privacy, schmivacy: 2 in 3 Americans don’t care if their smart devices are recording them


Privacy, schmivacy: 2 in 3 Americans don’t care if their smart devices are recording them

NEW YORK — Are the ads popping up in your smart device a little too spot on? Is it an eerie coincidence or are your smartphones and smart speakers listening in on everything you say in private? Privacy issues are a constant concern when it comes to digital technology, but a new survey finds many Americans are simply accepting they may not be alone in their own home. Researchers say two in three U.S. adults “don’t care” if their smart devices are always listening to what they say.

The report by Safety.com finds 66.7 percent of U.S. residents over 18 wouldn’t have a problem finding out a home gadget is listening in on what’s going on inside their home. Researchers polled nearly 1,100 people between the ages of 18 and 64 during December of 2020.

While tech companies repeatedly assure the public smart devices are not spying on their owners, not everyone is convinced of this. That feeling is particularly prevalent among older adults. The survey finds baby boomers are much more concerned about digital devices recording their conservations than Millennials or young adults in Generation Z. Adults in Generation X are split on the issue.

The poll also finds women are more unnerved about smart devices than men are, by a margin of seven percent. Unsurprisingly, residents in tech-dominant cities and regions are more accepting of potentially being recorded than Americans in communities with less high-tech development.

Not reading the fine print on smart devices


The Safety.com team says modern technology, capable of tracking every move we make, is becoming an unavoidable part of daily life. From smart speakers in the kitchen to smart cameras in the doorbell, this technology is built to record, watch, or listen to information in real time.

Although many might wonder how their interests end up in the next commercial their speakers play, researchers note few Americans really go through the terms and services agreement when downloading their various apps. They add skipping these privacy notices has actually become second nature to many tech users. Therefore, do many people really know how much data they’re agreeing to share with companies?

The poll finds the general sentiment regarding privacy and technology is “if someone isn’t guilty of anything, then what difference does it make if they’re being listened to?”

Digital amenities outweigh privacy concerns

As legal and privacy experts continue to debate how ethical that sentiment is, Safety.com finds more and more people are choosing convenience over their own privacy. This is especially true when it comes to owning smartphones.

Researchers estimate that around about 290 million smartphones in the U.S., or a staggering 80 percent of the consumer market. America ranks third among countries with the most smartphones.

The survey does find that more people are still a little wary of putting smart devices in their home. There are about 90 million smart speakers currently in American homes or vehicles, or about a third of the population.

How Cameras and Lenses Work… (interactive)

This interactive web page explaining all of the aspects of cameras and lenses is really one of the most informative resources that I have found about the subject.  Especially, the interactive sections that allow the reader to experiment with the various parameters of lenses and light make the entire understanding so much more complete.  This page is an amazing resource for photographers and videographers.

"Pictures have always been a meaningful part of the human experience. From the first cave drawings, to sketches and paintings, to modern photography, we’ve mastered the art of recording what we see.

Cameras and the lenses inside them may seem a little mystifying. In this blog post I’d like to explain not only how they work, but also how adjusting a few tunable parameters can produce fairly different results."

How to export 4k video with Premiere Pro CS 5.5

The bullet points for altering frame size need amending as the order in which you do them is wrong. You have to do it in this order or the dreaded “Invalid framesize/framerate for this Level. Please lower the Frame Dimensions, Frame Rate or increase the Profile and Level and try again.” keeps popping up.
• ignore the TV Standard (it’s a trick question), pick PAL or NTSC – it doesn’t matter
• set the Pixel Aspect Ratio to Square Pixels
• set the Profile to High
• set the Level to 5.1
• set the Frame Width to 3840
• set the Frame Height to 2160
• change the frame rate to match your footage (unless you’re doing some conversion magic)

If you’re editing 2.7k footage, the frame width and height are 2704 and 1520 respectively. The last two parameters (Profile and Level) are responsible for giving the initial error message by the way.
