In Binary Net Masking each Octet contains exponential bits from right to left:

1     1   1   1   1 1 1 1
128 64 32 16 8 4 2 1 (128+64+32+16+8+4+2+1=255)

So..

255.255.248.0 in binary is
11111111. 11111111. 11111000. 00000000 = /21 (we’ll get to the identifier in a minute)

255-248 = 7
Therefore 255.255.248.0 – supports 7 networks per subnet
255 – 248 = 7 networks

Or

192.168.1.0/21 supports
192.168.1.0-255
through
192.168.7.0-255

The next subnet supports another 7 networks.

192.168.8.0/21
192.168.8.0-255
through
192.168.15.0-255

So where does the /21 identifier come from?

All net mask identifiers start at /32 and go down.
32-21 = 11 mask bits
Count the zeroes in the Binary Mask!

11111111. 11111111. 11111000. 00000000 = /21
11111111. 11111111. 11110000. 00000000 = /20 (32-20 = 12 mask bits)

What’s the full net mask for the /20 identifier above?

1     1   1   1   1 1 1 1
128 64 32 16 8 4 2 1 (8+4+2+1=15)

/20 = 255.255.240.0 because 255–15 = 240

When considering the deletion or deactivation of a Facebook account you will ask yourself, what do I need here? What do I expect? Well here’s what you won’t get from Facebook anymore:

• Genuine interaction with people you actually know.  In fact many you know in your day to day life don’t follow you on Facebook.  Instead you are posting to a group of relatives or those who’ve found commonality in your political opinions, drama in personal life or shared interests.
• Advertising that is relevant to you.  Facebook is now saturated with ads that are straight scams.  It’s more dangerous to buy from an ad on Facebook than almost any other website including eBay and others saturated with Chinese knock-offs.
• Interaction with your children or grandchildren.  Almost anyone under 20 is not on Facebook.  They hate it.  This is good.  Don’t encourage them.

What Facebook has become is a haven for drama.  Old ladies and single moms pouring their desperation into heart felt memes and re-posted articles for attention.  At least a lot of the pout lip selfies from single women who mostly deserve to be single have subsided.  They’re learning, desperation and scorn pity is not attractive.

Now I admit on a rare occasion someone posts something on Facebook that is of interest.  It’s usually as simple as an event notice or sports highlight.  It’s certainly not worth 2 hours a day to any guy.  But women can’t put it away.  They enjoy what has become a platform for prying into the drama of each others lives.  Seeking sympathy and calls for “prayers” with vague bullshit posts like “Call for prayers, not sure how I’m going to make it through the latest” followed by a bunch of comments with little prayer hands clapped together and 40+ “Likes”.

Meanwhile a friend wins a half marathon and barely gets 10 “Likes”.  Why?  Because people genuinely don’t like to see others succeed.  Unless it’s some vague fem movement or cause or success then the “Likes” roll in.  But a genuine accomplishment, hell no.  That makes people feel pathetic about themselves because truth is, hate it or not, most people are indeed lazy, predictable and boring with a false sense of being entitled or deserving.  Don’t tread on this illusion.  Prop the lies they tell themselves for self-relevance and be “Liked”.

This, without any sugar on top is what facebook has become: A perpetuating platform of delusion and self-pity.

Anyone who pre-ordered a titanium Red Hydrogen One will get a free Aluminum model since the Ti have proven difficult to manufacturer.  They will also receive the Ti model they ordered once they start shipping.  Personally I’ve got to wait for the aluminum model to be available through Verizon and AT&T on Nov. 9th.  I haven’t been this curious about a phone in a while.  Especially interested in the camera.
