How to install memtest86+ on a USB flash drive

It comes a time when your computer starts trowing on you some errors, restarts, blue screens of death and the only thing left is to start checking what is causing the problems.

One of the first things you should check is if you have a faulty RAM module.

The best tool for testing memory modules is memtest86+.

Where you can find Memtest:

  • On HirenBootCD.
  • On almost every linux distribution LiveCD.

If you remember the previous tutorial on this site about Puppy Linux on a bootable flash disk drive, the thing is, we don’t have memtest86+, but we can install it on the good old trusty linux on a stick to use memtest on any computer that can boot from USB.

We assume you have the Puppy Linux installed on a USB flash drive and we start from there:

  1. Boot your computer on Puppy from your USB drive.
  2. Go to Menu > System > Grub4Dos bootloader config.
  3. Select your USB drive and press OK.
  4. On the next screen just press OK to install GRUB bootloader (GRUB is menu system that lets you choose the OS/drive/app you want to boot into).
  5. Open a web Browser and go to the Memtest download website.
  6. Download the 3rd link (as of Memtest86+ V5.01 (27/09/2013), the one that points to memtest86+-5.01.bin.gz
  7. On the bottom of your Puppy Linux desktop open the root of your Puppy USB drive (mine is sdf1). Leave this window open.
  8. At the top of the Puppy Linux desktop open the file app (the one with a home icon on a folder).
  9. Press the Downloads folder. Here you will find the downloaded Memtest file.
  10. Right click and Rename. Rename it to memtest.bin.
  11. Now drag the file from step 10 to the window on step 7 to move the memtest.bin file there.
  12. Now, on the location you moved the memtest.bin file (your sdfx location=the root of your USB drive) you can see menu.lst (the menu for the GRUB bootloader).
  13. Open menu.lst and after the entry for Puppy linux, paste this (without the 14.):
  14. # memtest+
    title memtest86+ v5.0.1
    kernel /memtest.bin
    boot
  15. Close the file and reboot Puppy.

 

After rebooting the Puppy Linux USB drive, you will get the GRUB bootloader with some entries:

  • Puppy
  • Memtest
  • Windows (if you have it installed)

All entries shoot boot the appropriate OS/apps but to test our installation select Memtest and wait until it checks your RAM modules. Press ESC when done.

There you have it, you can test the memory on any USB bootable computer in the world.

Have fun and if you have questions, please shoot!

 

Google Keep as an alternative to Evernote

As our busy lives unfold day by day we are bombarded with new and fast information, there is a huge amount of things to be done, to remember, to solve. Keeping all in your head is not second nature for all of us so we have two options:

  1. Keeping a physical notebook.

Pros: – It’s more natural – writing with pencil on paper feels great. Although in 10 years from now writing on an electronic device will be natural. – It’s faster and accurate – i bet that you can write and draw better than on a screen. – it can be found and read (not password protected), long after you die, when your grandkids find your notebook in the attic, in a big box covered with dust.🙂 Cons: – can’t set reminders – although using an agenda you can write new events on their specific dates and check the agenda regulary. – if you lose your notebook, all your planning is gone with the wind.

  1. Using technology.

Pros: – efficiency – use only one device to write, draw, take pictures, set reminders, record sounds etc. – syncing – your data can be kept in the cloud and can be accessed anywere, on any devices that can connect to the internet. Cons: – if you lose your password or get hacked you can lose all your data. ~~~~~ We’re in 2016, everybody have a smartphone so using one for note taking/planning it’s the most obvious way. I think the best and most complete note taking/planning service is Evernote. I will not make a review for Evernote but the bottom line is the Evernote app, the online service, the desktop app are very intuitive and very powerful. But, as i never used high end devices a hundred pound Gorilla like Evernote can run seriously slow, so i searched for an alternative. The most obvious choice was Google’s note taking app Google Keep. It’s simple, intuitive and very fast. Now, you have to move/copy the Evernote data to Keep but the bad thing is that as for this day, Google Keep can’t import any data. So if you have 2000 notes, you are pretty busy for the next 3 weeks. For a reasonable number of notes you can just copy/paste from Evernote to Keep. NOTE: One important thing is that the newly created/pasted notes in Keep will be at the top. So start to create notes from the least used/important up. With all above said, maybe you managed to end up with important and frequently updated notes at the bottom of the list. DON’T WORRY!!! Tap and hold on a note and from the menu above choose Properties (the 3 vertical dots) and Make a copy. Now you can see that a copy of the note in the depths of hell is now on top of your notes list. Now you can delete the bottom one. NOTE: You cannot select multiple notes and Make a copy! Google is such a step by step company. ^-^ This is not a VS debate, so please test both apps and see what app/service suit your needs. Have fun! ^-^

Since 2009, i am using Debian based linux distributions but the most part was on pure Debian and all my linux knowledge comes from Debian.

Debian GNU Linux is one of the first linux distribution and it is one of the most popular. If you take into account the most used linux distributions based on Debian, like Ubuntu and Linux Mint, you can say that Debian is the 3rd most used Operating System in the world!!!

The Dark Side of Photography

Just look at the detailed specifications on Nikon Rumors of the new Nikon D5:

http://nikonrumors.com/2016/01/05/nikon-d5-detailed-specifications-cf-and-xqd-versions-coinfirmed.aspx/

This in particular:

  • Highest ISO: 102,400
  • Extended sensitivity Hi5: ISO 3,280,000

ISO 3 million something!!! Keep that in mind…

 

Is this for real ?!?!

 

 

– Hey Evolution!!! You’ve got pretty lazy lately!!!

 

~~~~~

 

In 200+ years of photography we didn’t understand light completely and now we have to understand darkness?!?!

 

I just imagine a chat of a newbie photographer with a pro:
Newbie: What can i do to make great photographs?
Pro: You see maaan….you just gotta see the darkness.
Newbie: ?!?!?!

 

So we have image sensors that can see in plain darkness, but on top of that you can see a dark night light in daylight?!?! WTF?!?!
 ~~~~~
What will come next?
1. You will put 2 image sensors on your sunglasses and use the sunglasses to see at night? Once and for all, the sunglasses will benefit from their real name: sunglasses = glasses that bring the sun.
2. We will take photographs of black holes and get the real atoms of dark matter in a RAW file.
3. Adobe will switch Dodge and Burn together.
4. Kylo Ren will join the Light Side of the Force and he will dress like Snow White.
5. The Golden Hour will be at midnight.
6. Bats will be photographer’s best friends.
7. Flash units will substract light.
8. If your indoor pictures are not good enough, turn of the light.
9. Pixels will become darkxels.
10. The maximum aperture will be f/350 and the fastest shutter speed will be 2 weeks.
11. There will be only one White Balance preset: Pitch Black.
12. Lightroom will have a new module: “Black Hole Adjustment”:

May the ISO, light your Dark Side! ^-^

The fastest custom ROM for Motorola Defy Plus (MB526)

Some screenshots (yeah, you can take screenshots on Android 2.3.7.) to wet your appetite: O.O

This guide will show you my way to root and install WIUI 3.1.27 (Gingerbread) on a Motorola Defy Plus (MB526) with Bootloader 7 (version 9.1). The guide has 3 parts, determining what ROM you already have on your device, rooting the device and installing the custom ROM.

DISCLAIMER: I and all developers of those tools will not be held responsible for any damage you will do to your device and i strongly advise you to read all the internet regarding this, and decide if you will go or not this way. Rooting WILL VOID THE WARRANTY of your device. So DO IT ON YOUR OWN RISK!!!

~~~ The device (Motorola Defy+ MB526) stock stats: System version: 45.0.2310.MB526.AsiaRetail.en.03 Android version: 2.3.6 Kernel version: 2.3.32.9-ge281b6e hudsoncm@il93lnxdroid54#1 Build number: 4.5.1.134_DFP-231

~~~

Since i have bought my Motorola Defy Plus (MB526) device i’ve been testing many custom ROMs and also made some tutorials on rooting and installing new ones.

The thing that make us click (and the technology manufacturers exploit) is that we will never be satisfied with what we have, it’s human nature, we want the newest, fastest and the most feature rich devices (without buying new ones🙂 ).

So we have a low specs, old device that the manufacturer stop updating the original OS since the conception, the case here the Motorola Defy Plus coming with Android 2.3.7 with no official system updates.

But we want Android 4, 4.1, 4.4 and even 5 on our little matchbox but we can’t do nothing about it. This was true until really great guys made Cyanogenmod (CM) which is a custom Android that can run on old or new devices.

I have used CM 10, CM 10.2 and CM 11 (KitKat), yes, KitKat on the Defy Plus and Quarx is working on Android 5 Lolipop for the Defy Plus. O.o

Everything was fine but let’s be honest, you can’t put a Lamborghini engine on a Fiat Panda. That’s the case with newer Android on old devices, everything started to work slow…very slow.

So when you saw people around you just tapping and tapping and i had to wait a few seconds till an app fired up, i started Googling for the lightest and fastest ROM for Motorola Defy Plus. There were several ROMs people recommended but i first tried WIUI, a custom version of MIUI + Cyanogenmod. MIUI is a custom chinese version of Android/Cyanogenmod, used on XIAOMI phones etc. Yeah, you got that right, Android -> Cyanogenmod -> MIUI -> WIUI. Round and round we go.🙂

Please don’t get me wrong, all Cyanogenmod versions are amazing and you should try them. I used the versions above for very long time but i just needed more speed and different looks.

Ok, i got you dizzy already, let’s get our hands dirty.

~~~

PROLOGUE:

You can be in one of two situations:

  1. If you are on a custom ROM, probably Cyanogenmod. In this case you should download this stock ROM and flash it with RSD Lite. NOTE: This guide is based on a device with the specs at the beginning of this tutorial and the links are for software that worked for me. If you know other stock ROMs work for your device, please use them. The guide here, the XDA thread for WIUI said to flash CEE or Nordic stock ROMs, so you can try those instead of the link i gave you for the stock ROM. I will not go into details of how to flash a stock ROM, there are tones of tutorials online. After flashing the stock ROM, continue with PART 1 below.
  2. You are on stock ROM. In this case continue with PART 1 below.

PART 1 – ROOTING:

  1. On your brand new flashed stock ROM go to Settings>Applications>Development>Enable USB Debugging;
  2. On your device go to Settings>Applications> Enable Unknown sources;
  3. Download FRAMAROOT to your phone directly and install the apk;
  4. Open FRAMAROOT and just tap Ghimli;
  5. Your Defy+ is rooted!

~~~

PART 2 – Flashing WIUI 3.1.27.:

  1. Download and install on your phone 2nd init – ver.2.3; This version has the Clockworkmod 5.x version (now you understand the NOTE 1 at the beginning of the post);
  2. Open 2ndinit and press Install bootmenu – the red text will become green after successful install;
  3. Go here and read the thread. I downloaded and put on the root of the SD card the Stable GB+ 3.1.27. version. The installation guide say that the developer started with flashing the CEE or Nordic original Defy Plus ROM but it’s not the case. We have already covered steps -1 and 0 with the PROLOGUE and PART 1 of this tutorial. The following steps are from point 3. of the XDA guide. Also there is no need to download and install Google Apps, they are embedded in the WIUI ROM.
  4. Follow the guide on XDA forums starting from point 3.;
  5. Enjoy a fresh look for your Defy Plus with lighting speed. ^-^

New device stats: Android version: 2.3.7. Yes, it’s the same Android version as the original Defy Plus but it looks awesome and it works lighting fast. ^-^

PLEASE DONATE to the makers of Framaroot, Cyanogen mod and WIUI. If you choose to DONATE TO THIS WEBSITE, I will donate myself to Framaroot, Cyanogen and WIUI! ^-^
