I'll be buying a new computer...

I solved a mystery.
On Windows 7, I noticed task manager showing 8 cores, even though I have only 4.
I thought this apparent misnomer was due to my shoddy first installation of Windows 7.

Now that both OS's are running fine, I find that even Windows 10 shows 8 cores.
I did a google search, for anyone interested:

Apparently my CPU has "Hyper Threading" enabled, the linked article gives 'some' further details .... but doesn't really explain why....

Okay. So I took out the wifi card from one of the old computers. Doesn't seem to be anywhere on the optiplex 7050 sff motherboard to plug it in to. 
But that's okay. I might just use Windows 7 primarily for working offline - meaning more coding and no distractions from the internet, no worries about Windows defender (on Windows 10) deciding that my programs are malware, and all that follows - I.e., quarantine, deletion of executable, etc.

Of course will be a pita when I have to/want to post the code here.

I'll be looking for a suitable/compatible wifi card some time soon, even if it is a different USB wifi 'ding-dongle'. 

Have made a couple more tweaks to Windows 7, and Windows 10 on the i7 box.    And updated both backups accordingly. All is well in zeddville. With the obvious exception to the no wifi scenario on win 7, and inability to activate it.

Why Windows 7 at all?

Run Windows 7 in a VM. That will use the host machine's network.

Why Windows 7 at all?

Because I likeee.     (Almost as much as xp)

Why another layer between me and bare metal?     (If that was the ONLY option, MAYBE)

I need another gift to myself for Christmas. 

I am considering a new tablet to replace my old, ancient, (prehistoric even) iPad.
There is a sweet deal on an android 14 tablet at amazon. And I have an itchy finger. Lol. I had thought (very briefly) of getting a Windows tablet, but at 4 or 5 times the price, maybe not. (I have the laptop for Windows portability, when I have a hankering to code outside and away from my computer) A newer iPad also is out of the question, as they are also pricey.

I only need it to surf the internet really (maybe playing some games, too) so the less expensive option is very appealing.... 

^ add to that, watching YouTube videos.

Good with new tablet, you can install many apps, but don't forget security on newer android prevent you from install apps on external sd card,so cheapest = least internal memory,so might need buy tablet more internal memory
Wondering how much GB ram on PC and want to see your 64 bit sieve code again, because it should be possible improve it to use 16+ GB on mine

The new tablet arrived and is much faster than my oldest iPad. My other iPad runs fine, is the one I use for watching documentaries while I fall asleep. 
My new tablet, I mainly use on the back porch. I don't use many apps on it, just what I need for browsing the internet, watch YouTube videos and for a couple of sudoku games that I like to play sometimes. Looking for a good chess app.

Everything loads much faster than either of my two older iPads.
As far as ram, my new desktop pc as well as the laptop both have 32 GB in them, not sure really about the tablet - how much ram it has - the documentation is poorly written and probably a little misleading. It says I have 4 GB + 6 GB ram. Why not just say 10 GB ram???

In testing, the new pc is just under twice as fast as the old pc(s) for everything I have run tests for. The laptop is also much faster, maybe 1.5 times or so than the old pc's.

I am a very happy camper all around with my new electronic toys.

well with development in WIFI made it faster than when your old Ipads was ,can it have something todo with loading faster? recent router had both old WIFI and the new 5G WIFI which is faster,but shorter range
if your newest tablet has SIM card, it probably support the latest 5G network
also lot faster RAM and cpu in your new tablet

Quite possible.

btw I attached 'primes64' in the above post... happy coding. 

On the subject of primes, I found some C code to test whether a given number is prime or not (actually several variants that do the same thing). I have had that code for a while, I want to convert it to assembly.... Coming to a new post near you, soon.    I'll be using 32 bit for the conversion, though.
Prime number fun fact:
Remember 867-5309? (Jennies phone number)
8675309 is prime.

Thanks for the code
Different or same primes Algos running on several threads,different using strength and weaknesses
Also div on several cores or
sieve
mul eax
Mov [eax],false
Algos Better suited for SIMT than SIMD
That's part of what my SIMT thread is about

Android tablet WiFi can have speed like 300 Mbps used with 5G mobile connection.
Wifi specs 2,5 / 5 GHz gives 400 / 867 Mbps

Android 5G phone in test gave near 600 Mbps, as testing was near SIM card limit.

wifi 6 or 7?
it has diff bandwidth

[TimoVJL]

Honor Pad X8 have only WiFi 5 and LTE
