Messages within Messages App on macOS Not Delivered

A couple of weeks ago I had an issue with my iPhone and decided to log out of iCloud and then log back in. That fixed whatever problem I was having (I don’t even remember what it was) but from that point on the Messages app on my MacBook Pro stopped being able to send messages. Anytime that I would try I would just get the “Not Delivered” error message. Clicking retry didn’t help either. After some frustrating searching of old forums and searching through settings to find anything that I could turn off and turn back on, I finally decided to just log out and log back in. It fixed the problem.

Ninety Percent of People Don’t Know How to Use CTRL-F

Last year I read, “Crazy: 90 Percent of People Don’t Know How to Use CTRL+F“, an article from, and I decided then to make sure that as a school teacher I was going to try and reverse that statistic. Thinking about it today, I realize I have never posted here to help get the word out, so I’m doing it now.

CTRL-F will help you find text on a web page in most modern browsers. Press and hold Ctrl and then press F, follow that by typing in the words or words you want to find. Mac users try Command + F.

There — I just saved hours, if not days of your life.

CTRL-F Why you no work on paper?

Oh, and as a bonus tip, if you want the same search functionality in your personal (paper) book library, give the My Library feature of Google Books a try — it might just blow your mind.



In addition to running very slowly, lately I’ve been getting some unexplained popups on my computer. They’re very strange, sometimes appearing with the Internet Explorer logo (which I don’t use except for updating windows).

Some of the popups have the Firefox logo but then have an Internet Explorer error message. Some other of the pop-ups are coming up as error 404 but that is likely because of my hosts file. (If you don’t have a modified hosts file, I highly recommend you get this one. (instructions)

I ran a scan using Hijackthis and found, what I think are, suspicious .dll files in the windows/system32 folder:

  • hoyolajo.dll
  • pamukuhu.dll
  • subiluje.dll

I don’t know what these files do and the limited search results aren’t helping. I’m posting this here with the hope that someone else may shed some light on the situation.

VLC: Best Media Player?

I think VLC is the best media player out there. No more worrying about codecs or corrupt files, VLC does it all—not to mention, it even plays DVDs!

VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, …) as well as DVDs, VCDs, and various streaming protocols. It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network.

iTunesHelper.ex.exe has generated errors…

I’ve got a small problem with my iTunes and ipod—they’re no longer talking to each other. It seems to be related to an error I started getting a few days ago, “iTunesHelper.ex.exe has generated errors and will be closed by windows. You will need to restart the program.”

I did a search and found one other poor soul that seems to have had the exact same error, but this was back in 2004. Unfortunately no one responded to his request:

I’ve installed the software that came with my iPod but keep getting a Program Error “iTunesHelper.ex.exe has generated errors and will be closed by windows. You will need to restart the program”. When I open iTunes I then get another error message “The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod’s software”. I’ve uninstalled and re-installed the iTunes software about 20 times and still can’t get it to work. Can anyone help me?

And since his plea went unanswered, my question is: can anybody help me? I haven’t reinstalled 20 times yet, but twice and it still hasn’t done the trick. Perhaps somebody visiting has had the same problem and knows how to fix it?
