By Special Correspondent Jessica Yee, originally published at CITIZENShift

Editor’s note: Yesterday, December 6th, was the National Day of Remembrance and Action on Violence Against Women in Canada, in commemoration of the Montréal Massacre.  Jessica Yee wrote the following article to draw attention to the racialized nature of violence against women, among other things.

It’s December 6th 2009, and many people have been asking me what I’m thinking today. What do I think about this day where 20 years ago, a man walked into a Montreal engineering college and shot 14 women, specifically because they were women. Interestingly enough, I had to fight to have a female Aboriginal Elder open and be present at the event I’m speaking at today because the organizers “didn’t want to detract from the meaning of the day” by me asking her to say some words. It’s the 20th anniversary of the École Polytechnique shooting, and people keep asking me, so what do I think about that?

I’m thinking a lot of things in fact. Yes, I’m from the next generation of women who were too young to remember when the murders actually took place, but I suppose I belong to the current generation of women who identify themselves with feminist politics and have heard from the foremothers of this movement in Canada about the significance of remembering the day, and to never forget it. They say, “Women Won’t Forget” on December 6th. But as a young, sex working, multiracial, bisexual, two-spirited, Aboriginal woman, I think that sometimes, especially at these December 6th type events, women DO forget a few things:

Sometimes women forget that as Aboriginal women, we are five times more likely to die of violence than any other race of women in Canada, and that women have been going missing and being murdered in our communities by the thousands, for hundreds of years.

Women forget that while we show up to vigils and talk up a nice speech about some “poor prostitute” who died on the streets, we simultaneously judge, shun, and degrade current sex workers and speak against decriminalization – something that might actually help protect us.

Sometimes, women forget that same-sex violence should be taken as seriously as man to woman violence and that we really don’t talk about violence in the queer community as often as we could.

Women forget that Elder violence is very real and is happening, but also that a lot of it is committed against young women, who deserve the opportunity to speak for ourselves as youth, not be spoken for by yet another generation of first or second wave feminists that don’t want to give up their power yet.

And if you are reading this and thinking to yourself “well, I don’t forget that on December 6th” please, don’t expend your energy to get mad at me. Direct that passion towards reminding another woman now that you’ve read this, or someone else for that matter who is forgetting, or who just doesn’t know.

For the record, I refuse to have another argument with someone about what this day is “only” supposed to commemorate.

What about you?

Sanyo gives rechargeable batteries a design makeover. The snoopy look alike battery checker has a nose that changes color depending on the status of the battery to be charged. Unfortunately, this is only going to be produced in limited numbers and only in Japan. But on the plus it's great to see a product like the battery getting a little bit of design lovin. On another level, since the explosion in use of the ipod and other itoys when was the last time you actually used a pair of AA batteries?

The PowerSafe jumper cables look like your standard jumpers, with a pair of terminal clamps on each end. However, midway through the cables' length is a small electronic brain that monitors the state of the connections and only lets power flow when everything is hooked up just right. So, if you accidentally connect your cable backward on either end, the system will display a red warning light and the power stays off. If you accidentally touch the loose ends of a live cable, the red light glows and there are no sparks. If there's a short of any kind, even within the dead battery, the red light glows and everyone remains safe.

I'd bought my DS Lite on the UK release day back in June 2006. Despite the complaints regarding the hinge cracking on the left side of some early units, I never had any such problem. I was lucky... or so I thought. 

Yes - my DS Lite has lasted more than 3 years, and now the hinge has decided it could take no more. I'm now part of the club. Thankfully, the crack doesn't prevent my DS from opening and closing - so my quest to finally finish The Legend of Zelda: Phantom Hourglass can continue. Update: Oh no it can't - I've just realised that I've left the charger at home. Damn.

I keep seeing and hearing lots of jabs at Apple for not having a removable battery in the iPhone, and I understand why some people might want that. It's pretty well known that battery life when using apps and data services can be very short, and it would be nice to pop off the spent battery and pop on a fresh one and continue on.

But honestly, even if you did get an extra battery included with the phone (which isn't going to happen) you would still have to power down your phone, swap batteries, and restart the phone. I would much rather have something like a Mophi JuicePack or some other external battery life extender that would not interrupt usage. These battery extender options also probably cost about the same as what apple would likely charge for an additional replaceable battery. Some even act as a case, which is an added bonus. Have you seen how much some of the cases cost. Add that together with the at least $50 a replaceable battery might cost, and you probably would have less money in the battery pack/case. But that isn't why I don't want a removeable battery.

The reason I DO NOT want a replacable battery is because of the Find My iPhone feature. As it is now, if you have a a Mobileme account and have the Find My iPhone feature enabled, and if you are responsible enough to keep your phone locked when not in use and it gets stolen or lost, it cannot be easily powered down without the pass code. If there were a removable battery, it would be very easy for someone to steal an iphone and immediately remove the battery until they could get it to a computer to do a restore or something that would enable them to turn off the tracking feature. Without the removable battery you at least have a bigger window of time to be able to track the phone down. Especially if the person who took the phone is not familiar with the features.

I do wish the battery life was better, but I love that I have a chance of tracking it down should I loose it or it gets stolen. Therefore, I really hope Apple does not give the iPhone a removable battery.

Paul says...

(Finally.  I've always wanted to write a blog post with N ways to do something.)

To begin with, I reject two obvious steps: run a different, lighter distro; and don't use KDE.

 I use Ubuntu on my laptop for one overriding reason: hardware compatibility. Slackware was my first distro, and I loved it. I love it still. On my desktop it worked fine. On my laptop—it didn't. I spent insane amounts of time—months—trying to make X work on that laptop. I learned a lot about Linux. I learned so much about Linux that my next distro was… Cygwin.

 I never ever want to go through that again. I never ever even want to be reminded of that experience again. On a desktop, I am willing to try other distros. Never on a laptop.

 As for KDE: this is my caprice. I just like KDE better than GNOME or Xfce. It just seems better thought out. Take a simple example: shutdown scripts. It's easy enough in any desktop environment to create scripts to run on startup.  Only KDE provides a straightforward facility to run scripts on shutdown. (This saves me having to explicitly kill the Emacs daemon every time I shut down.)

 (To be honest, KDE4 has been severely testing my patience, but they seem to have their act together now. I rarely have to switch to a virtual console and pkill -9 kscreenlocker anymore.)

 (I know there's a whole world of tiling window manager's out there, but they strike me as gimmicky, like most efforts to Emacsify things that aren't Emacs. I love Emacs. I'm writing this in Emacs.  But anything beyond readline compatibility just crosses my wires—frustrates me with false expectations.  I want all of Emacs or nothing.)

 Anyway, there were supposed to be instructions.

 I assume you know the basics: turn your modem off when you're not using it, lower the screen brightness, leave the sound off, etc.

 The first way to save power: turn off the Flash plugin. This isn't Ubuntu-specific, but it's the best place to start. Just having the flash plugin on—without having any Flash video playing—accounts for half the processor activity on the machine.

 (In Opera you can toggle plugins on & off with two keystrokes: <f12> u. I assume there are ways to do this in Firefox. Google it.)

 The second way to save power: lower the swappiness. Swappiness weights how likely the kernel is to use swap. The default for Ubuntu is 60—absurdly high. On a laptop you never, ever want to use swap. The performance penalty of not using swap is always preferable to the battery drain of requiring the hard disk to mimic RAM. You can try this out:

 sudo bash 
echo 10 > /proc/sys/vm/swappiness

 (You could set it to 0 but this might screw things up if you run something very demanding, which you shouldn't do, but you might do without meaning to. I keep it at 10 and the machine never uses swap.)

 (sudo bash in the above is a gutless root shell. You could sudo su root or sudo -i too but this won't work with your usual sudo make -blt sandwich approach.)

 To make this permanent put vm.swappiness = 20 in sysctl.conf

 The third way: mount /tmp as a ramdisk. This is as simple as adding a line to the end of your /etc/fstab:

  
tmpfs /tmp tmpfs defaults,nosuid,size=1g,mode=1777 0 0

 N.B. Whenever you are watching Flash video, the video is being written to /tmp. If you must use Flash on battery power, this makes it a lot easier on the battery.

 (You could also write a autostart script to create a series of folders in /tmp & symlink all your browser cache folders to them. Exercise for the reader.)

 The fourth and fifth ways: powertop and laptop-mode. Powertop is a neato program that analyzes processor activity and show you what's hogging cycles (like Flash). Laptop-mode (included but deactivated in Ubuntu) is a neato kernel feature that spools and spaces out writes to the disk. They come together in this list because although Powertop will suggest and execute changes to your system, it can't make any of these changes permanent. Laptop-mode lets you do that. First run powertop. Write down all of its suggestions. Then go to /etc/laptop-mode/conf.d/ and start poking around. All of the changes laptop-mode suggests can made permanent by altering the appropriate configuration files here.

 (And turn laptop-mode on: in /etc/laptop-mode/laptop-mode.conf set ENABLE_LAPTOP_MODE_ON_BATTERY=1.)

And that's five. With just these five changes I actually get the battery life (under normal use) that the ad said I would.

Nuclear batteries have been safely powering devices such as satellites, Soviet lighthouses and underwater systems for years - but they are evolving to become even more useful. Let's face it - most of us don't own satellites or lighthouses.

The batteries already had an extremely long life and high energy density compared to chemical batteries. But they cost a few quid and are very large and heavy. 

Now researchers at the University of Missouri are developing a nuclear battery that is lighter, more efficient and smaller - conveniently small. And of course they are capable of powering things for ... well, longer than you are going to live.

Don't get the wrong idea about the "nuclear battery". It isn't hazardous. Though it does generate electricity from atomic energy like nuclear reactors, it doesn't use a chain reaction. It uses emissions from a radioactive isotope to generate electricity. So there’s no risk of the battery in your pace-maker giving you a coronary chernobyl.

How small? It is currently the size and thickness of a single penny, and is intended to power various micro and nanoelectromechanical systems. But the really cool bit it is that the innovation uses a liquid rather than solid semi-conductor.

Radioactive batteries, apart from giving out useful energy, also tend to damage the lattice structure of the solid semiconductor. By using a liquid semiconductor, the team thinks it has minimized the problem.

In the future, these egg-heads hope to increase the battery’s power, shrink its size - even to the width of a human hair - and try various other materials.

俚電池的市場規模
這種成長是非常的可怕的,是絕對不可忽視的................

根據日本研究機構富士經濟的預估,明年全球市場規模才3000台的電動汽車,到2020年(這是我們活得到、看得到的)市場規模將暴增到130500台,而關鍵零組件鋰電池產值,將從明年的4億日圓成長到2020年的3132億日圓,成長度達782倍。

約合台幣1122億。但更重要的事,電池這個產業更可以在以手機的預付方式,這種產業也並不多見,因為所有的消費者都不願意在消費前拿出錢來,所以這個電動車等市場,是非常值得切入思考的市場與運營模式。

電動車的話題也隨著最近的油價標漲之時,最近這個話題非常的明確。所以,這個話題需要不斷的去研究。以及去定位我們應該要所處的。
