There is a lot of misunderstanding about Java, partially because of the confusion with the similar sounding JavaScript. Java was developed by Sun Microsystems almost 23 years ago. Sun was acquired by Oracle Corporation. Java was intended to be a “write once – run anywhere” programming language using a virtual machine that can be run on any processing platform.

I tried to resist writing on these because they are everywhere in the media already and there have been new developments almost daily as companies frantically prepare their responses to the vulnerabilities. You can follow new security updates easily by looking at the Security Alerts and Updates on our own SenCom web site. The technical details and many helpful links and manufacturers’ responses are also contained in the following alert by Homeland Security. Continue reading →

There are two methods that most people use for handling email. The most common method these days is using a web-based email client. Examples are Hotmail, Yahoo, AOL, Gmail, or anything else that opens up in your web browser to connect to the host email servers to view or send email that is stored by the servers. The other method is an email program or app that installs and runs on your computer and connects to the host email servers to download the new mail to your computer for storage. Outlook Express and the older versions of the full Outlook program available from Microsoft as part of the Office suite (not to be confused with outlook.com which is web-based) are examples.

There could be many reasons for needing or wanting to delete old internet accounts, if for no other reason than removing personal data from inactive accounts to reduce the chances of it being hacked. Finding instructions on how to do it may be a bit of a challenge. Sometimes the instructions provided by a particular internet site are hard to find or understand and are explained more clearly by other sources that provide “how to” articles or videos.

In October we were hit with two particularly onerous public alerts about security threats known as KRACK and ROCA. KRACK is the WPA2 vulnerability, which potentially affects the security of anyone using wi-fi communications. ROCA is the encryption key vulnerability, which potentially affects anyone using devices or software that uses encryption keys generated from chips made by Infineon, which has about 30% of the market share for such security chips.

Beginning with version 57 which is planned to be released on November 14, 2017 support of legacy extensions such as LastPass will also end and they will be replaced with WebExtensions. This change has also been incorporated in Microsoft Edge and Google Chrome browsers. Continue reading →

I have encountered Windows XP and Windows Vista computers running extremely slow recently. Checking Task Manager for the highest CPU processes (with “show processes from all users” selected) showed an instance of the svchost.exe process at a constant 99% CPU usage on computers with single core processors or 50% on computers with dual core processors (one core at 100%), and the process was using by far the highest amount of memory of all processes. Searching the internet for clues on the cause led to several articles on the symptoms being related to a problem with Windows Update. Continue reading →

Windows Search has been around for several Windows versions, and frankly I never gave it much thought and rarely used it until Windows 8 came along, and then I found it was the quickest and easiest way to find where Microsoft had put all of the stuff I used to know where was in Windows 7. I was aware of the option to index your hard drive or not in the disk properties, but had never made the connection with Windows Search until recently when I came across an article suggesting to speed up old computers and free up disk space by turning off the indexing if you do not rely on Windows Search that much and don’t care if it takes longer to find something when you do use it occasionally.

I have never been a fan of loading up my internet browsers with extensions (or plugins or add-ons), mostly because they used to be offered by a third party (other than the browser developer) and they modified the browser programming code which sometimes made the browser slower or misbehave or could even introduce malware. All of the major browsers have moved to a different programming structure that does not allow extensions to modify the browser code. Instead, the code for the extension is kept in a separate secured area with strictly controlled access to the browser. This has made browser extensions much more secure and safer to use.

What is the Creators Update?
Windows 10 undergoes major updates introducing new features once or twice a year. On April 11, 2017 the next major update that will begin rolling out is called the Creators Update because of several new features planned to enhance the creative capabilities of the operating system. Unfortunately many of the planned new features are not ready to be released, so the update will not be as significant as first expected. It is still a major update in that it completely replaces your existing version of Windows 10. Continue reading →

You may be familiar with the use of PayPal for sending money from your PayPal account linked to a credit card or bank account to another person’s PayPal account for Ebay purchases or receiving payments from others when selling items on Ebay. It has been around for a number of years and since being split off from Ebay, it is being accepted by many other types of stores and for peer to peer payments. There are a number of competing services available now. TopTenReviews “The Best Mobile Wallets of 2017” lists Android Pay, Apple Pay, Capital One Wallet, eWallet, Gyft, Key Ring, LevelUp, Samsung Pay, and Walmart Pay in addition to PayPal.

Around this time of year I like to start looking at seed and nursery catalogs for some new plants to try out. I ordered some plants from a couple of places in the past and since then I have been inundated with catalogs from numerous places. Looking through them I began to notice that many of the items in different catalogs seemed to be identical and then I noticed that most of them had addresses in Bloomington, Illinois. Two were on one street with numbers very close together and two were on another street with numbers very close together. Could there really be that many different companies operating nurseries next to each other in one city the size of Bloomington? Continue reading →

Most of us rely on passwords for secure access to accounts on various websites. Besides the possibility that weak passwords can eventually be broken, there are more and more elaborate phishing schemes to trick you into entering your password in a fake login screen that looks legitimate but is there to steal your password. Many major companies are now joining an alliance to support a standard 2-factor authentication process that is easy and economical to greatly improve login security. Continue reading →

Tips for what I look for in a laptop:
I look for at least a 6th generation i3 processor. i5 is better but will cost a little more. I7 will be the most powerful, most expensive, and will run the battery down faster. It is essential for running the latest video games that the youngsters play.
AMD, Atom, Celeron, Pentium processors are too slow in most cases and I would avoid them unless maximizing battery life is your primary concern and you can live with a sluggish computer. Continue reading →

The 7th generation of Intel processors (also known as Kaby Lake or Kabylake) are showing up in the newest computers, right now in tablets, notebooks, and laptops, and by the first quarter of 2017 in desktops. This should mean there will be some good bargains for existing 6th generation (Skylake) processor-based computers for those who do not feel the need to have the latest technology available. So what do the newest processors offer? For most users, probably not a whole lot. Continue reading →

We are in the last few days of the free Windows 10 upgrade from Windows 7, 8, or 8.1 which will end on July 29. If you have Windows 8 or 8.1, there is no reason I can think of to pass up the free upgrade to Windows 10. If you have Windows 7, especially on an older computer, I can understand your reluctance. I have two older computers that have not been upgraded and I keep wondering if I might regret not doing it later even though I really prefer to keep them at Windows 7 for the foreseeable future.

It is still not known if waiting until the last days of the free update will include the next yet-to-be-released major Windows 10 updates or not.

A modem converts the signal from your internet service provider, whether it comes from telephone, cable TV, or fiber services, to an Ethernet signal that provides the internet service to your computer or other internet-connected devices. It could be called a dial-up modem, DSL modem, cable modem, or fiber modem depending on the type of internet service you have. At a minimum, the modem will have an AC power adapter, an Ethernet output port that provides your internet signal, and an input port and/or cable from one of the following: Continue reading →

We also may have accumulated a lot of bookmarks (Firefox, Chrome) or favorites (Internet Explorer) in one browser and wish to copy them to another browser on the same computer or to a browser on another computer. These are the topics on what will generally be referred to as bookmarks for simplicity, for all three of the mentioned browsers. Continue reading →

In the last month, I have talked with 4 people who have had encounters with fraudulent computer “technicians” after getting a popup on their computer looking like a blue screen of death (BSOD) that claims to be from Microsoft informing them of viruses or malware on their computer and providing a telephone number from a “Certified Microsoft Partner”. Fortunately, all of them got suspicious and ended the call before providing their credit card number, but just letting a fraud have remote access to your computer for a moment can put you at risk of having your files encrypted or deleted by them if you refuse to pay for their service.

Here are a few recent news items I have run across while browsing on cold winter days.
End of Google Chrome Support for Windows XP and Vista and Older Mac OS
Starting April 2016, Chrome will continue to function on Windows XP, Windows Vista, Mac OS 10.6, 10.7 and 10.8, but will no longer receive updates and security fixes. Since most malware is introduced to your computer through either browsing or email, this could increase your security risk if you continue to use Chrome after April on these older operating systems.

As the number of people migrating to Windows 10 increases, either intentionally or accidentally, I have been hearing some common questions.
How do I revert back to the operating system I had?
If your system was updated to Windows 10 unintentionally or you are having problems with it and want to revert back to your previous operating system, remember that you only have 30 days to do so from the day it was updated.
