Comment Re:Color blindness is useful though (Score 1) 137

As someone who has been dumbfounded by this since he first went to Japan as an exchange student over 20 years ago, I have a theory why this may have happened. It is hypothesized that the color Blue was one of the last colors for people to discover/appreciate enough to assign it a name (Radiolab has a great show on this). Accordingly, "Ao" was assigned "green" first but as the concept of "Blue" started to materialize, "Midori" became the new "Green" so that "Ao" could start covering things that were "Blue." That would explain why phrased implying youth ("He is still Green", etc. . .) use the character for "Ao," as they are old phrases that would have been invented before the concept of "Blue" came along.

Of course, since the characters for these words came from China, there probably is a significant Chinese factor to this story (I remember speaking to a Chinese lady who thought that Chinese language influence had been responsible for this nuance in Japanese). Perhaps someone with more experience with Chinese can try to fill in this part.

Right. . . over the period 1999 to 2009 the return was ~ -34% (I suppose we do not need to annualize that to show that it is definitely below +7%/year). . .

Besides, the idea that investment horizon is the only relevant factor when making investment comparisons is financial homeopathy.

Stocks and corporate bonds are some of the most volatile, high risk asset classes you can invest in. Only magical thinking would make one conclude that would be anything close to investing in a project to reduce one's electricity bill over a long period of time. A closer comparison would be to purchase a US Treasury bond and hold it to maturity (go look up those returns instead).

It is your choice to be ignorant about finance. However, Slashdot appears to have an epidemic level of financial ignorance going on over here. Think carefully before posting. When a Geek hands over his hard earned cash to the banksters, nobody wins. . .

When you want to submit codepatches, always look for existing patches that are sitting there. Are the maintainers communicative and do they accept patches? Then it is worthwhile to submit something. If they aren't, it becomes quite hard to expect them to do accept your patch.
Not saying you are to blame, you aren't, but there are healthy projects with responsible maintainers and unhealthy projects.
Some people seem to be made to make something and throw it over the fence, while others are apparently good at maintainership.
Not every person and every project is the same. Take your picks and be carefull where to invest your time.

Ah, Slashdot. . . News for Nerds and the financially challenged. . . There are some very basic problems with your comparison, like:
-WHICH years does the S&P "mostly" do better than 8%? For instance, an investment lasting from 2000 ~ 2007 would have net you NEGATIVE return in terms of real dollars. . . You are comparing investments that have completely different levels of risk (Finance 101 fail).
-Again, corporate bonds? Most batteries have an extensive warranty period, so this investment could be structured as something similar to a risk free investment (~0% right now). . . .
-Large used batteries usually have a significant salvage value.

Not trying to be harsh on you, but the modding certainly shows the deficiencies of the Slashdot community when it comes to finance related discussions. . . What is the point of being a smart Geek if you throw your money away due to lack of finance basics?

Comment Pragmatism versus Idealism (Score 2) 146

Seeing cororate interest in Open Source / Free Software grow bigger, I am slowly moving towards the camp of the Idealists, like RMS.

Just looking at Linux, the kernel. It's great that it is being used in Android, and that it has a billion users there. But Android is not free in the practical sense for the enduser. They can never update their device to a newer version, because the hardwaredrivers are tied to the kernelversion. "Just buy a new device", Google and the manufacturers say. Just what GNU was all about in the beginning, "just buy a new printer".

Similar corporate interests are happening at Red Hat, which is pulling all the sheets in their direction. Their ideal is to have every Linux distro be similar, like RH. And we are "happy" to just take their software and use it, because it is so pragmatic.

The good thing about Free Software is, you can always fork it. But the barrier to do so is quite high, so there needs to be a lot of frustration for that to happen.
We will see what will happen to GNOME3, Mate and Cinnamon. I wish the later 2 projects the best.

Comment Re:And why not? (Score 1) 227

Wait. . . we are trying to limit global warming by 2 Celsius over the next 85 years. 50 Celsius over 400 years is over 10 Celsius over that same period. Something seems amiss. . .

Worse, your link points to energy PRODUCTION reaching that level in 400 years. TWICE the energy amount produced by nuclear power is lost as heat, so we would reach that point much earlier than 400 years (not to forget that only a portion of solar energy falling on Earth is absorbed).

There has got to be a better answer out there somewhere . . .

And why is it that the woman is the one to take care of children?

I don't know if you have noticed that men and women are different. Women happen to be more suitable for taking care of babies because they can do one thing men can't: breastfeed.

At least, that is one of the reasons why my wife took 6 months maternity leave, and luckily in those 6 months our situation changed so that we could manage without her working. And we have had more children since, so she is still at home.

Of course, we do realise that she will have fewer years of work experience when/if she returns to work, and this also not earn what she would have if she had continued working. However, the investment in our kids/family life is worth it.

Comment Most problems or biggest problems (Score 1) 307

The question is about the most problems, and dying storage would be the right answer for me then.

The biggest problem I had however was with a cheap power supply. For some days I had a peculiar smell in the house. Then suddenly there was smoke coming from the back of the pc, and the start of flames.
I will only buy power supplies from main brand names now anymore, it scared me quite a bit.

Comment Re:Life Imitating Art (Score 1) 282

Correct. However, Orwell did not anticipate that the general public would be the ones to have the majority of networked cameras that they could use to keep tabs on the government. I have cameras installed at my home, but I am not just going to share with anyone unconditionally. A string of events would have to occur first before I would even consider sharing specific footage with the local police. I believe anyone else (including in the UK) shelling out their own money would be inclined to do the same (else risk their own footage being used against themselves).

So, in short, yes, everything will be recorded just like Orwell's predicted. However, the economic tendency is for everyone to have a piece of the footage pie and be able to choose when and with whom they share it with.
