‘A mesh network is a group of devices that act as a single Wi-Fi network; so there are multiple sources of Wi-Fi around your house, instead of just a single router. These additional Wi-Fi sources are called points or nodes’.
– definition from support.google.com

My Wi-Fi signal downstairs was too weak for my new smart TV, so I opted for a mesh network to get a better signal downstairs — instead of adding a Wi-Fi extender to my existing network. Per my limited understanding, Wi-Fi extenders repeat the signal and thereby slows down its speed. Many times extenders broadcast a new network name, which could be a hassle for a user moving around a lot in the space.

I went with Google Nest Wi-Fi. For a small apartment, one node will do, but for a bigger space two nodes or more can be used.

Once I had the issues with my old Wi-Fi-enabled modem-router resolved (aka throwing it out and replacing it altogether with just a simple cable modem!), the set-up of the Google Nest Wifi mesh network was straightforward.

Here’s a black Tesla Model Y that I found here on 17th Ave. It has a range of 315 miles, and sports a very sleek look.

‘While the introduction of the Model Y wasn’t as groundbreaking as the hoopla around Models 3, S, and X, it’s clear it is going to be big. SUV and crossover sales continue to dwarf sedan sales in the United States, and the Model X is probably a bit too radical and expensive for most potential EV* buyers, so the Model Y appears to hit the sweet spot buyers are looking for: an EV with plenty of cargo space and a high sitting position’.

‘Tis now the very witching time of night,
When churchyards yawn and hell itself breathes out
Contagion to this world: now could I drink hot blood,
And do such bitter business as the day
Would quake to look on.
-From William Shakespeare’s ‘Hamlet’ (written 1599-1601), Act 3, Scene 2.

At 2 a.m. Sunday morning local time here in the United States, it was that silly moment of the year again. Clocks were made to ‘spring forward’ by one hour (adjusted to Daylight Saving Time).

Of course, only some clocks spring forward by themselves.
The others all have to be adjusted manually.

I ran into Tally the inventory robot in the grocery store last night. I think it’s a good thing — letting a robot do the labor-intensive and repetitive process of physical inventory checking.

‘Yes, but does the store not have a count of the SKUs* on the shelf in its database, anyway? one might ask.  The store does, but human shoppers take items off the shelf and misplace it when putting it back, or – rarely, I hope – steal it. Or employees could unpack items in the wrong location, or forget to remove sale prices, and so on.  So there are always discrepancies between the SKU count in the database and the physical count on the shelf.

Two weeks ago, I discovered an entire shoe box of my old ’80s and ’90s film negatives (35 mm) and slides in my brother’s house.

We promptly went out and bought a cheap flatbed scanner (Epson perfection v370) that can scan slides and film, and I have been patiently feeding the scanner reams of 35 mm film.

The plan is to upload all the pictures to Google Photos, but only after I had date-stamped and geo-tagged them as well.

That way the Google photo engine will be able to search for, and group all the faces for me, put them on a timeline sequence, and also on a world map by location: very nice.

My iPhone (not even a year old, Xs) died all of a sudden today, even though it was about 75% charged.
I finally revived it by trying the Device Firmware Update button sequence several times:
Press & release Volume Up button;
Press & release Volume Down button;
Press and hold the Sleep/Wake button ..
.. and then the Apple logo came on and it came back to life.

Who knows what constellation of firmware, software and hardware settings was to blame for the system ‘s black-out .. but from now on, I’m going to close all open screens and turn the phone completely off & on again, at least once a week.

Wow .. that drone shot down by Islamic Revolutionary Guard Corps was not a garden-variety drone.
It was a Northrop Grumman RQ-4 Global Hawk.
Here are some of its attributes:
Wingspan: 130.9 ft / 39.9 m (wider than that of the Boeing 737)
Range: 14,000 miles / 22 500 km
Speed: 357 mph/ 574 kph
Ceiling: 60,000 ft/ 18 288 m
Endurance: 34 hrs
Cost: $200 million

So what will Trump do now?
He talks tough, but on Thursday called the incident ‘a big mistake’, meaning the Corps made a miscalculation and was not following orders from President Hassan Rouhani.

At this perilous time the United States has no Secretary of Defense (has not had one for more than 6 months, for the first time ever).
And now Trump seems to be the one that has to push back against Secretary of State Mike Pompeo and National Security Advisor John Bolton. Both seem to be itching to start a war with Iran.

Not a good situation at all.

Geotagging* a (digital) photograph is the recording of its geographical location, by assigning at least a latitude and longitude to the image. Sometimes other fields such as altitude and compass bearing could also be included.
The old film pictures I had scanned in for my iPhone and iPad photo albums have no geotag information, and so I geotagged them manually.

I have been very fortunate to be able to travel to many places in the world.
Check out some of the more unusual geotags that I had added to my pictures, below.

*Geotagging is done automatically by today’s smartphones, and by GPS-enabled digital cameras. The method I am using for scanned pictures, is to use an obsolete picture editor from Google called Picasa. Inside Picasa, one can call up a desktop version of Google Earth, that allows searches for places all over the globe, and the geotagging of their coordinates onto the picture.

I remembered another unresolved issue with my iTunes music collection: the bitrate of the .mp3 version of the songs I had originally transferred into iTunes from CD, was as low as 160 kbps. This was oh, some ten years ago.

Nowadays, there is an ‘Apple Lossless’ option which will replicate the original CD in iTunes (bit rates of 900 kbps or more). The enormous storage capacity available on smartphones these days makes it possible to transfer and carry all of one’s CDs as-is in iTunes .. but is it worth it? The files would be up to 6 times larger than the original 160 kbps ones.

So my strategy is to upgrade only my very favorite CDs, say up to 30 out of the 300, that I now have in iTunes.

I’m still doggedly maintaining my iTunes library of music, even though music purveyors like Apple and Amazon are trying hard to make me let go and subscribe to their online music. For about $10 a month, one can get access to a vast library of old and new music (50 million songs), as well as curated playlists from music buffs.

But if one has listened to recorded music for several decades (me), and have bought music CDs in places all over the world*, it’s really hard to let go of all that. Why not keep the music on CDs AND upload it into a searchable collection of 2,000 songs to carry on your smartphone? It

*I left my vinyl collection behind in South Africa in 1995; gave it all to a friend .. but have replaced some of them with CDs, since.
