NPR recently had a report on a computer that cost U.S. $9 for a CPU from Next.Thing.Co.
and the possibilities it opens up for new innovation is very exciting.
It will allow access to an open-source platform of hardware and
software in education and creative individuals that were once held back
by high costs and rigid frameworks.
I once joked about a future
where computers would be so inexpensive that we would purchase them as
we would incandescent light bulbs. Now, that future is fast
approaching as the C.H.I.P. will ship out in June of 2016.
Let’s us all wish Wikipedia a
happy birthday as it turns 15 years old this week. It has come a long

for free information supported by the community. Thank you!

Do you have a website that you would like to know when it is down? Do
you have more than one website? Or, are you looking for a thrift
solution to monitor your websites? I located many commercial services
that offer free versions of website monitoring services, but I wanted
something that was simple to use and open source. One such method was
developed by Amit Agarwal
lagnol.org which uses Google Scripts on your Google Spreadsheets
account. It checks a website every five minutes and alerts you when its
down via e-mail.
Here are the steps I used to install it to track my websites :
- Sign-in to your Google account using your Gmail or Google Apps login.
- Click here to copy this Google sheet into your Google Drive.
your website URL's in cell B2, separate each URL with a comma if you
are entering more than one site (I added "-test" to one domain name to
test it out), and your email address in cell B3.
- I did not wish to receive alerts by text message, so I left cell B4 as "No".
- Click on Website Monitor menu in your Google Sheets toolbar.
- Click Initialize and you’ll get a pop-up asking for authorization.
- Grant the necessary access.
- Go to the Website Monitor menu again and choose “Start Website Monitor” to begin the monitoring process.
- Close the Google Sheet.
will receive an email when the site is "down" every 5 minutes until it
is restored. Each "down" result will be logged in your spreadsheet with
Google notified me of the of following error after a few days of running the script:
|Service using too much computer time for one day|
solution was to increase the amount of time between checks to my
websites from 5 to 30 minutes. You can access the script by clicking on
the link (Copy of Website Monitor v4.0) in the email you received from
Google, or simple clicking on Tools>Script Editor if you have it opened in your Google Drive account:
I opened the script labnol.gs and updated the following code by changing the 5 to 30:
// Setup trigger that runs every 5 minutes
.everyMinutes(30) // Updated from 5 to 30 minutes to reduce computer time
sheet.toast("Google Docs will now monitor your website(s). "
+ "You can exit this sheet!", "Initialized", -1);
This is the maximum number of time for it to run. Then, saved the update and restarted the script.
I'll keep you all posted if any new messages are received.
Do you search the web and visit a page only to find it is either
loading slowly because it has too many adds? Or, do you find it has more
adds than content? App helpful app or browser plugin I use and
recommend is, Adblock Plus.
It is an open source project which has improved my experience on the
web by removing the adds that are too abundant on some websites.
Furthermore, it blocks tracking, banners, pop-ups and video ads making
your online experience more pleasant.
Most of all it's free and very reliable!
Have a great day!
