Connecting PC and monitor via HDMI: “no signal”

Problem
At my workplace I got a new monitor (27″) that came with an HDMI cable. I connected the monitor and the PC but the monitor displayed a “No signal” error. I tried it with a VGA cable and it worked fine but the screen was not sharp enough. I had the impression that the lower quality was caused by the VGA cable. Hmm, how to make that HDMI connection work?

Solution
The solution is trivial. You need to select HDMI connection in the settings of your monitor, in the menu :) Really, that’s all. And the difference is clearly visible. Now my screen is sharp, much better than the VGA. So if you have HDMI connection, use it.

playing with Facebook’s graph search

June 19, 2014 Leave a comment

Here is a nice post on Facebook’s graph search with several examples: link.

Some commands:

  • People from [Your Town] who work at [Company Name]
  • Restaurants nearby liked by my friends
  • Local events this weekend
  • etc.

Automate with IFTTT

IFTTT is a great service that enables users to connect different web applications (e.g., Facebook, Evernote, Weather, Dropbox, etc.) together through simple conditional statements known as “Recipes”.” (via wikipedia)

IFTTT stands for “if this then that”. That is, if a condition is met, then an action is triggered.

Here is a nice introductory video. It shows how to get an SMS if it’s going to rain tomorrow:

 

Let’s see another example. Say you have a favourite TV show that you want to watch as soon as possible. When the new episode is out, you want to get an email notification.

As reddit user ACreatureVoidOfForm pointed out, we need Showrss.info and ifttt.com. “Create a page on showrss for all the shows you watch and generate an RSS feed. Create a rule on ifttt to email you when a new entry is added to the feed.” (tip from here)

send an email at a specific date and time

Update (20140512): There is a better way. Check out this post.

Problem
I have a favorite TV show whose new episodes I want to watch as soon as possible. However, I don’t want to keep in my mind the release dates. When a new episode is out, I want to get an email notification.

Solution
At http://next-episode.net you can check out the release dates of the episodes (example). LetterMeLater provides a service to send emails at a specific date and time (it’s free up to 30 emails/month). To the release dates I added one day and set LetterMeLater to send emails at that day.

It may not be the best way to do it. If you have a better method, let me know.
