New scam by sharing posts on Facebook / Πώς να αντιμετωπίσετε τη νέα απάτη στο Facebook


[Ακολουθεί και στην ελληνική γλώσσα]

In case you are the owner/manager of a Facebook page, you may already had a notification about one of your posts being shared by another page, which asks from you to confirm your account or get blocked!

This page claims to be “The Facebook Team” and asks you to visit a web-page in order to confirm your account.

DON’T click this URL!

Instead, report this page to Facebook 😉

  1. Visit the profile of this page by clicking on the name
  2. Click on the ellipsis button (the three dots) and select “Report page”
  3. Select “It’s harassing me or someone I know” (see side picture)
  4. When you are on the “What You Can Do” box, click all “Submit to Facebook for Review“, “Block [Page name]“, “Hide all From [Page name]” options.

Today (Thu 9 Mar 2017), I had two notifications for two of the pages I own/manage, so I thought it would be useful to inform any other owners/managers who may be notified also.  🍀


Πώς να αντιμετωπίσετε τη νέα απάτη στο Facebook

Αν διαχειρίζεστε κάποια σελίδα στο Facebook, σήμερα μπορεί να σας ήρθε κάποια ειδοποίηση ότι κάποια σελίδα κοινοποίησε κάποια δημοσίευση της σελίδας σας με το μήνυμα ότι πρέπει να επιβεβαιώσετε το λογαριασμό σας, αλλιώς κινδυνεύετε με μπλοκάρισμα! (Δείτε την πρώτη εικόνα στην αρχή του άρθρου)

Επειδή αυτές οι σελίδες το πιο πιθανό είναι να θέλουν να κλέψουν κωδικούς (λυπάμαι αλλά δεν επισκέφτηκα το σύνδεσμο που λέει να πατήσω), ΜΗΝ ΠΑΤΗΣΕΤΕ στο σύνδεσμο που σας εμφανίζει.

Αντίθετα, κάνετε τα εξής:

  1. Πατήστε πρώτα επάνω στο όνομα της σελίδας που κοινοποίησε τη δημοσίευσή σας.
  2. Πατήστε στο κουμπί με τα αποσιωπητικά (τις τρεις τελείες) και επιλέξτε «Αναφορά σελίδας»
  3. Στο παραθυράκι που θα εμφανιστεί επιλέξτε «Παρενοχλεί εμένα ή κάποιον που γνωρίζω»
  4. Στο νέο παραθυράκι με τίτλο «Τι μπορείτε να κάνετε» πατήστε με τη σειρά και στις 3 πρώτες επιλογές, ώστε (α) να υποβάλλετε στο Facebook τη σελίδα για εξέταση (ώστε να επιληφθούν της υπόθεσης), (β) να μπλοκάρετε τη σελίδα και (γ) να μη βλέπετε τυχόν άλλες δημοσιεύσεις της.


Σήμερα (Πέμπτη) είχα δύο παρόμοια περιστατικά σε δύο από τις σελίδες που διαχειρίζομαι (από δύο διαφορετικές σελίδες με πολύ γενικές επωνυμίες — φαίνονται στις εικόνες) κι έτσι θεώρησα καλό να καταγράψω τον τρόπο αντιμετώπισης. 🍀

Variety wallpaper changer on Ubuntu 14.04

After upgrading to Ubuntu 14.04, I noticed that Variety, the desktop wallpaper changer I’m using, stopped updating the desktop wallpaper (xfce here), although it continued to change the photos (by updating the application’s indicator icon).

So, I started looking into the details and I found that I had to change two lines in ~/.config/variety/scripts/set_wallpaper script.


xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s “” 2> /dev/null
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s “$WP” 2> /dev/null


xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorLVDS/workspace0/last-image -s “” 2> /dev/null
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorLVDS/workspace0/last-image -s “$WP” 2> /dev/null

Duplicity fails on 3GB /tmp

Backup application Duplicity has just filled up my /tmp, located on / partition with 3GB free space, during verification of a full backup and, finally, reported ‘failure’!
After quitting Duplicity, I have 1GB less free space on my / partition.

I wonder how much bigger the /tmp space need to be…


Update [2013/11/19]:

I’ve found the ‘lost’ GB into ~/.cache/deja-dup directory [naturally] (or /root/.cache/deja-dup if it runs under gksudo), but I still don’t know why 3 GB of temporary space are not enough.

Yet another list of RSS feed readers

So, Google Reader is closing down its services tomorrow and the vast majority of its users have already chosen their next reader for their RSS feeds, since many bloggers and news sites have written about the alternatives.

“Hidden” gems of VLC

Today I found out the power of the “Devices” items in the VLC application.
With that I mean the option to record:

  • a videocast with the computer’s camera [Video capture]
    Video effects, although can be seen on screen, are not recorded.
  • the usage of some application through its window (or the whole desktop, if you like) [Screen capture]

Audio capture didn’t worked for me; maybe it’s a configuration thing or a conflict, since video recordings had also no audio at all.

“Bad request Error 400” for GMail on Firefox

For the last 2-3 days I had an unusual situation to deal with. Whenever I tried to visit my GMail account using Firefox, the response was:

Bad request
Error 400

 At first I checked with the other browsers (Chrome, Opera and Midori) I have installed on my system. All connected without reporting anything.
Then, my next guess was misbehaving addons, but as I tweeted:

So, what is wrong with #GMail on #Firefox today? “Bad request Error 400” (even with all addons disabled)
— A. P. Tsompanopoulos (@aptlogs) March 22, 2012

Since that approach didn’t helped either, I decided to remove the GMail-related cookies. I used the “Remove cookie(s) for Site” addon and it deleted 78 cookies I had for GMail.

Unfortunately, I don’t know which cookie was the “bad” one, but after deleting them I was again able to reconnect without problem.

No editor toolbar on WordPress

Just a quick note for me and anyone else with a similar problem:

If the rich-text editor on a WordPress blog is not displayed correctly (i.e. no visible toolbar or no access to writing area — I recently had both symptoms) then the problem might be an incompatible library used in a plugin.

For my case, the solution of the problem was to deactivate the “Spelling & grammar” box of the JetPack plugin by selecting “Learn more” at first and then “De-activate”.

Think like a virus!

Not related to L.A.M.P. technologies, but a useful quote to remember if you are a net admin:

As a network administrator, you have to think like a virus.
How can I get into a network?
Which points are the most vulnerable?
Once in, what’s the easiest path to destruction?

From the “Windows sources” magazine, July 1997 issue, page 158, “NT admin> Stop network attacks” by David Chernicoff

How to hide “Mark all as read” in new Google Reader

With the new redesign of Google Reader (the Google+ look-alike), I’ve noticed a new annoying behavior today.
The “Mark all as read” in now a button that takes and keeps focus. This means that if you press it once with your mouse and, then, go to another group of posts and press space to view the next page, you ‘ll end to mark all posts in that group as read!!! [because the “Mark all as read” button has got the focus]
The easier work-around solution I’ve found is to hide that button and use Ctrl-A Shift-A [edited] whenever I want to use the [main] functionality. I know that by hiding all options I miss the option to mark all older than a date as read, but I can live with this instead of marking as read all posts by mistake.

Since I work with Firefox and use Stylish, this hiding is easy. Just add a new recipe, name it something like “hide mark all in GReader” and insert the following in it:

@-moz-document url-prefix(, url-prefix(, url-prefix(, url-prefix( {
    span#mark-all-as-read-split-button { display: none !important; }

and enable the Stylish recipe when you want to feel safe.

How to hide the new Facebook news feed

In case you are using Firefox and you want to hide the new Facebook right-column news feed, here is a quick hack.

  • At first, you need to install Stylish, if you don’t have it already.
  • Add a new blank style with the following lines in it and give it whatever name you want.
  • Energize! 😉

 The code:

@namespace url(;

@-moz-document domain("") {
  .fbFeedTickerStory { display: none !important; }
