Just Finished Reading: Moonwalking with Einstein #books

leave a comment »

I’ve had an interested in memory for as long as I can remember, so when I saw Joshua Foer on The Colbert Report I went straight to the store to get myself a copy of his book Moonwalking with Einstein. I read it over three days, and haven’t given it a chance to sink in yet.

Through out the book Foer briefly dips into techniques that he used to improve his recollection, although he calls it memory in the book. He starts with Simonides’ memory palace as his basis and continues by learning the Major System, below, and the PAO system – where every two-digit number from 00 to 99 is represented by a single image of a person performing an action on an object – which he uses for committing cards to memory three at a time.

Major System

Although the book is mostly about how Foer trained to become the US champion in one year – and it only touches on the underlying techniques used – it shows the power of not just the mind, it shows that perseverance can make the unlikely possible.

Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.

A great read.

Proof of Concept: RAM Disk for your own Protection #police #law #government

with one comment

Museum Boerhaave – 1930 Wiess electromagnet

In continuation of my article: Data Erasing for your own Protection I got into a discussion about other ways to protect you data from law enforcement.

I was told by a former law enforcement member that after the crime scene has been secured that the the computer tech checks the computer is functional and then has the equivalent of a mover ship the computer, like a box, to the computer lab. The issue with this being that a mercury switch and power source could be used to zap the computer with the needed Gauss to erase/destroy the hard disk.

Another method would be to use a RAM Disk, whether this is a physical[1] or virtual RAM Disk. The first has the advantage that in the case of a brownout the data is saved for X hours, although this could be a disadvantage too, another disadvantage is that you may have a memory limit which is imposed by the hardware. The advantage over the physical RAM disk is that a higher amount of memory can be allocated, although you don’t get the protection from brownouts.

Important to also remember is that there is also a data remanence with data in RAM[2], which also should to be mitigated. This may be possible by passing an electric charge over the memory to erase them, although I have yet to find relevant references.

A third method may be by raising the temperature of the hard disk to above the Curie Point[3], which with effect the magnetics of the disk. I will need to investigate this more too.

Embedding part of the computer in epoxy still applies to all the above.

  1. Gigabyte I-RAM DDR PCI Virtual RAM Disk Drive SATA W/ Backup Battery – backup power lasts ~16 hours and it supports 4Gb RAM.
  2. Data remanence: Data in RAM
  3. Curie Point

Non Daily Habits

with one comment

I have trouble remembering to do things, like going to the gym, and when I do I generally procrastinate, like hanging up the washing. *stops writing blog and goes to hang up the washing* For myself I set alarms, calendar items and reminders, for me it’s easier to remember things I do daily than anything I do on an irregular basis.

So imagine my joy when I read How to Maintain Not-Quite-Daily Habits. The article contains 5 pieces of advise to make it easier to keep your habits:

  1. Make it daily anyway
  2. Use placeholder habits
  3. Chain Habits
  4. Make specific commitments
  5. Turn habits into appointments

Another thing I have in the house are whiteboards, they aren’t just for developing ideas and giving presentations, but also as handy reminder pads.

I can’t remember where I got this, possibly from LifeHacker.

Free Memory with RUNDLL32

leave a comment »

I’m not sure I ever mentioned this in other blogs, but there is some fun stuff you can do with the program RUNDLL32.EXE, you can find it in other places too. It’s a tool for making function calls from windows libraries. You can basically call any command fitting the requirement:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
Obviously it is sometimes used incorrectly.
