Anti-virus and Nirsoft woes.
My Toshiba laptop came with the TrendMicro OfficeScan anti-virus installed by default under the NUS network admin rights. I have always regretted not opting out of that shit.
Recently, TrendMicro has been giving tons of false alerts on many freeware programs that were already on the device for years. Couldn't uninstall it without the password set by NUS Computer Centre. Was about to bring my computer down to IT Care in school to get it removed, luckily a ex-coursemate from CS1010E told me that the passwords are usually one of the below:
- password
- trend
- trendmicro
- nusadmin
- nus
I don't know how many of the above were actually passwords that they used on computers sold in NUS, but the one that did the trick for me was "trend".
Also, recently Nirsoft has had to remove the command line functionality from his programs, I believe there are none left which have not been replaced by the non-command line versions. This was apparently prompted by Google which is now the self-proclaimed police of the internet.
The command line version was infinitely more useful, and is still available to those who know where to look (for now). I won't post the link as it may cause it to be taken down that much quicker, but here are some hints:
- Look for the last compiled Nirsoft package before 17.09.2014. As of now it is still available for download.
- Have you ever played Zahada? If so, the link can be found somewhere on this page. You know what to do. It is literally right here.
- It is technically freeware, so older versions can be redistributed.
- Ask people from forums like HWZ, PortableFreeware or gHacks to pass you the old versions.
- Ask me to pass you the older versions.

Ni No Kuni - Kokoro no Kakera, Harmonica Tabs
Gonna start tabbing songs in my free time. Tabs are cool, because the same melody can be played for any key diatonic, no need to get a brain cramp transposing notes from the score.
Diatonic harmonica tabs:
{-6}6: -6 means to do a very quick accent with -6 before the 6
4 6 -6 6 5
-5 {6}-5 5 -4 -3
4
1 3 3
1 3 -3'' 3 2
-2'' -2'' 2 -1 3
2 -1 1 -1
1 3 3
1 3 -3'' 3 2
-2'' -2'' 2 -1 2 -2'' 3
1 1'' 1
1'': Getting B3 is impossible.
I don't like the 2 hole draw bends because I can't do it, and there's no 1'' too. So... Shift up one octave!
Diatonic harmonica tabs:
{-10}9: -6 means to do a very quick accent with -6 before the 6
7 9 -10 9 8
-9 {9}-9 8 -8 -7
7
First 4 bars can be kept in original octave too.
4 6 6
4 6 -6 6 5
-5 -5 5 -4 6
5 -4 4 -4
4 6 6
4 6 -6 6 5
-5 -5 5 -4 5 -5 6
4 -3 4
-Work In Progress-

PC3193: Kerr Effect
The Kerr effect experiment is relatively simple, there is really only one set of data to be collected and each data run only takes up to an hour.
The huge issue with this experiment is the alignment of the optical elements, as with any optics experiment. Even when you align the setup as best as you can, there will be a couple of discrepancies with your obtained data and what is expected.
Here are my report and data:

Kerr Effect Report
Apparently, attributing the temperature dependence of PLZT birefringence in absence of an electric field is not enough to explain the discrepancy in half-wave voltage measured.

PC3193: Scanning Tunneling Microscope - Manipulating HOPG scans with Gwyddion for lattice dimensions.
If you have had the misfortune of using the Nanosurf STM, you would no doubt be struggling to achieve a clean atomic resolution scan with your terrible self cut Pt/Ir tips.
Fret not. A shitty scan is all you need.
Look at this ugly beast, blegh. Open it in Gwyddion and select the topology channel.
Choose a funkalicious colour gradient that gets your jive
on. Here’s a personal favourite.
But since this doesn’t fly with THE MAN, choose Gwyddion.net.
1 - Median Line Correction
2 - Remove Scars
3 - Remove polynomial background
4 - Shift min. data value to zero
5 - Correct affine distortion
Choose 2D ACF & HOPG preset (NOTE: your integrity is tested here, more on this later)
Adjust the grid to fit as well as you can, then hit Refine
to get it spot on. If refine fails to get it perfect, retry and do a better job
fitting it.
Spank the OK button
6 – 2D auto correlate function
Colour it. Take a moment to notice that it is ugly as heck.
I’m sure you are thinking this:
“Wow, so ugly, why didn’t I just 2D ACF’ed the picture
before doing that Affine distortion crap, YOU LYING FIEND!”
Fret not, see, without Affine Distortion, the 2D ACF would
give a nice picture with bad results. Observe.
Gross... What about the corrected one?
Nice results, BUT the affine correction overwrites the original image's scale info if you have chosen the "Exactly as specified option" which was used in the example shown. Thus giving you perfect results, at the cost of your integrity.
So either get your scanning angle adjustment right when taking the scan, or just use the "Preserve X scale" option.
K bye.
- Exactly as specified
- Lattice vectors in the corrected image will have the specified lengths and angle between them. Scale information of the original image is discarded completely.
- Preserve area
- Lattice vectors in the corrected image will have the specified ratio of lengths and angle between them. However, the overall scale is calculated as to make the affine transformation area-preserving.
- Preserve X scale
- Lattice vectors in the corrected image will have the specified ratio of lengths and angle between them. However, the overall scale is calculated as to make the affine transformation preserve the original x-axis scale. This is somewhat analogous to the scale treatment in Drift compensation.

Bowling revisited!
We recently decided to start bowling again. Since no other couple activity manages to strike a chord with both of us; thanks to someone's over aggressive competitiveness.
However, there are a couple of issues with this:
- Bowling is mildly expensive
- Bowling bag is heavy as heck and there are no available lockers for rent
- We lack the strength and stamina now
- The bowling equipment is in bad shape, the balls stink for some reason and my shoes are disintegrating. Although to be fair, my shoes have been disintegrating for about 10 years already...

Light meter alternative - DIY printable exposure calculator card!
In anticipation of the Zorki 4K that I have ordered from the 'bay, I started hunting around for an affordable light meter but quickly found out that even the cheaper light meters were already going to cost more than the Zorki. Bummer...
So I set out to learn the Sunny 16 rule, and found a really good article:
But then I needed a form of reference that I could bring around, at least until I internalise everything.
So I started crafting an excel table, the idea was to print and cut out various slips with columns of shutter speeds corresponding to common ISOs and sliding them up and down against another column containing apertures. It turned out okay, but was unwieldy.
Then I found the printable exposure calculator by Andrew Lawn:
http://www.squit.co.uk/photo/exposurecalc.html
It's basically my excel table except 10 times more refined.

Left to right: Crap, non-Crap |
I first printed one out on some 70gsm paper and used tape for the window and to reinforce it, but it was too flimsy for my liking. Used white card paper for the next one and it turned out nicely.
Slide the ISO to the exposure value and Done. |
The sliding bit did not slide well due to friction, so I added clear tape to the edges, problem solved.
Leftover plastic for window |
The window should be covered with something rigid otherwise the paper tends to bend outwards. I used leftover plastic from those pesky blister/clamshell packagings.
I can't wait for the Zorki, my sis has loads of unused 35mm film in the freezer from her Lomography days, it seems like such a waste so I shall strive to use them all up!

I really like this view, not just because it's right outside of my house, but because the buildings form a nice U shape to frame the sky. As long as I don't angle my head down to look at the sewage canal, it's a great view and it's mine to look at everyday.
