Intel i5-7xxx are quad core, but then they probably use too much power to be run fanless, so this is likely something new.
There are plenty of Intel boards with quad core on them, and if you open it up to all AliExpress, there must be thousands.
Anyway, quad core isn't THAT important until you want to run VirtualBox, then the cores and the RAM have to be shared out.

As far as those prebuilt Micros are concerned, what do you think would be adequate configuration? 

For doing what?

the i5/4010U.  How does that processor stack up overall IYHO?

No idea.

8 Gigs RAM/128 Gigs SSD.

If you've got that much data to store I'd be surprised.

Do these things come with Linux pre-installed?  What Linux?  If not, then you are going to have to learn how to install stuff.  That's not "pro" stuff.  Diagnosing problems and fixing software is pro stuff.

Forget I ever asked.  Your expertiese is not proving very helpful here.

RE


Yup.  :coffee:

RE, Palloy's instructions for the Virtualbox running of Linux inside windows are okay but they lack something important. I researched all this a couple of years back and got reliable instructions from Ask Leo on how to do this. The problem is that defending Linux from hacking in general and malware in particular can be tricky. Norton does that, of course, but, at least according to Ask Leo, retail security software is NOT rock solid on Linux but is extremely reliable on Windows. Since I have (reluctantly) been forced into windows10 with my i3 new Dell Inspiron machine, I received the unexpected pleasant surprise of not being a target of the NSA malware recently being used to hack windows versions  :emthup: :icon_sunny:  (Palloy posted here on it recently - It's an article in the Intercept).

At any rate, security is NUMERO UNO for me. And I don't want to even try to keep up with the hackers out there. So, I pay Norton about $84 a year to do the heavy lifting while I continue to use CFS in dealing with e-mails and suspicious web sites. Norton has been good to me. They have saved my arse on several occasions over the last DECADE.  :emthup:

Linux has a lot of attraction for me but I never got around to that Virtualbox testing of it. Maybe someday.

When I had a total disk failure two computers ago, I was able to run Ubuntu from a CD to shop for a new computer with a dial up backup I still had. I no longer have dial up (I save $19.95 a month by not having it  :icon_mrgreen:) so that is no longer an option.

The last time my hard disk failed, I was STUCK without a computer to shop for a computer so I had to do it by phone (UGH!).  :P

Yeah, I should have a backup hard disk with an image of my operating system to avoid that, but I haven't gotten around to that yet. Hopefully, I'll get one this summer.


Hope this helps you, RE.  :icon_sunny: I'm certain Palloy will, of course, not be impressed AT ALL.  ::)

Well, I'm impressed with your commitment to security.   :emthup:

Norton (now Symantec) AntiVirus does run on Linux, but since they charge for it and it's not open source, Ubuntu doesn't make it available, and nobody would use it.  ClamAV is the recommended free and open source solution.  Symantec SAV has to be a complete re-write of the Windows version, because the arrangement of the file system on Linux is completely different from Windows (no C:\  at the top of the hierarchy of directories, no Registry, etc).  99% of all viruses are written to target Windows machines, and won't run at all on Linux. 

Even if someone were to write a virus specifically for Linux, and sneak the file into the file system somehow, it could only run under your user's account, and so would only have access to that part of the file system that you own - /home/palloy/  (being equivalent to C:\Users\palloy\ ).  So it could trash your files, but it couldn't trash other users' files, or the OS itself, which belongs to "root". 

And you DO have a backup of your files, don't you? - yes, of course I do, every day at 01:00 am.

Suffice to say that in 5 years of Linux, on what is now 5 machines, I have never even been warned about a virus, let alone been infected by one.   :icon_sunny:

6 machines if you count my Android smartphone, but I rarely switch it on, and NEVER let it talk to the other computers on the home network, because I don't trust Android and because the Android version is no longer supported.  :(

Ubuntu is owned by Canonical, who I suppose make their money by providing paid technical support.  However the Linux community experts provide free support at places like AskUbuntu, StackExchange, etc.


Well, I haven't gotten around to total image backups although I think that would be ideal. What I do, since I'm too cheap to get another hard disk or even a solid state USB disk on a stick to put a recovery thing on, I take my CDs and copy my NEW document and picture files, current screenshot of desktop with programs list, favorites list, names of latest program additions and new sketchup graphic files I've doodled in my spare time to it in compressed form once a month.

If the hard disk dies before I make my recovery thing, I'll just have to wing it.  :P

Having a tiny forum also provides me with a second backup to my pictures and screeds that won't perish with my hard disk. I do not trust the cloud and will never store zip on it. Yes, I know the gooberment, microsofty, my server and the NSA knows every keystroke I have ever made and has stored all my activity since I was born (on the internets), but they don't like to admit that.  :evil4:

So, I do what I can.   8)

Make a Powerful Generator From a Dead BLDC Motor

by omars2   in electronics


Hi!

In this instructable, I'm going to teach you how to convert a dead Brushless DC motor into a powerful 3-phase energy generator.

The process is really simple and after going through this instructable, i am sure you will be able to do it for yourself.

The absence of brushes in them makes it unique when compared to other generators because its efficiency is much greater than the brushed ones that undergo losses because of the friction.

When a bldc Motor motor stops working.It is usually it's driving circuit that dies.

Why Are Ice Cubes Often Cloudy?
 

Tap water typically contains benign impurities such as lime, calcium, fluoride, nitrates, magnesium, and other organic elements. When water freezes, it hardens from the outside in, and those impurities are pushed into the center of the cube, causing the ice to have a cloudy appearance. However, boiling the water first will remove most of the impurities and provide clearer ice.

Ice, ice, baby:

Using bottled water that has been purified using a reverse osmosis process, or another type of distillation, will also improve ice cube clarity.

Cloudy ice is also related to how quickly the water is chilled. Most home freezers cool very rapidly, and tiny air bubbles (actually, dissolved air) get trapped before they can dissipate.

High-end restaurants use systems that freeze pure water slowly, in layers, so that air bubbles have plenty of time to escape.

Making a Powerful Generator From a Blender Motor DIY


Quote
Hi!

In this instructable, i will teach you how to transform a 220 volts Blender motor into a powerful generator without any additional circuit.

Blender Motors are actually the universal Motors which are capable of operating at both AC or DC inputs.

High power DC Motors are really difficult to find at home but the Blender motors are easily available almost everywhere and from that point of view, this project is of great importance.

Since they operate at high voltage therefore they also generate high voltage of 200V to 300V.

Step 1: Requirements:

mobile charger/laptop charger
48 volts to 220 volts inverter
bulbs
1-Universal motor
jumper wires
bulb connectors
thread

Step 2: Connections:

The above Universal motor has four wires.Two wires both black in colour are for the armature while the other two wires black and red are for the field.

Now take a laptop charger and measure its output voltage with a multimeter. I have used a 19 volts laptop charger though you can use any voltage range from 5 volts which is for a mobile charger to 20 volts which is usually for the laptop chargers.

Connect the two output wires from the laptop charger to the field wires of the universal motor irrespective of the polarity.

Once you do that, the field winding gets activated.Now take an inverter and connect it to the armature terminals of the Universal motor.

To the output 220 volts or 110 volts side of the inverter, connect the load bulb.

Now take the plastic thread and wound it around the shaft of the Blender(universal) motor.

Step 3: Testing:

After your completed the previous steps, all you have to do is hold the Universal motor with one hand and pull the plastic thread as fast as you can with your other hand.

You should see your bulb glowing brightly.

The maximum voltage that i could achieve with the hand generation test was 122.8V DC as can be seen in the picture.

The maximum power that it can generate should be 200W though it depends a lot upon the mechanical rotation and the power fed to the field.

To understand it better please watch the video here. *
